[0002] Prefabricated walls are increasingly used. Some prefabricated walls used for decoration have concave patterns, which result in uneven thickness of the finished wall and discontinuous internal structure of the wall. However, the existing manufacturing methods for decorative prefabricated walls often fail to take into account the impact of uneven thickness or discontinuous internal structure of the finished wall on the accuracy of quality inspection results. Therefore, how to make targeted adjustments to the quality inspection process based on the distribution of the concave patterns of the actual finished wall is an urgent problem to be solved by technical personnel in this field.

Clamps are sleeved on both outer ends of the tension screw rods, and the two clamps press the integrated template from the outside to the inside. The above scheme has the following problems: It fails to determine a targeted regional analysis method according to the actual distribution of the concave pattern of the target molded component, so as to adopt targeted quality inspection methods for different regions, resulting in low accuracy of the quality inspection results of the target molded component, and thus making it impossible to make timely and effective adjustments to the preparation process. Summary of the invention

[0005] To achieve the above object, the present invention provides a method for producing decorative materials from construction waste, comprising:

[0006] Using a preset production process to prepare a target material including recycled micropowder, and using the target material to manufacture a target molded component;

[0007] Acquire a preset component image of a target molded component;

[0008] Determine a regional analysis method according to the proportion of the concave area of ​​the preset component image, the regional analysis method is to determine a set of similar areas according to the overlap of the concave patterns between the sub-image areas and the molding difficulty coefficient, or determine a regional division method of the concave area according to the proportion of a type of concave pattern to obtain a key detection area;

[0009] Determine a quality inspection method according to whether a preset component image of a target molded component has an intaglio pattern, wherein the quality inspection method is to perform ultrasonic inspection or X-ray inspection on the target molded component;

[0010] The preparation adjustment strategy of the target molded component is selected according to the overlap coefficient between the quality abnormal area and the concave area of ​​the target molded component. The preparation adjustment strategy is to adjust the preparation grinding time or the activator dosage during the preparation of the target material.

[0011] Furthermore, the preset production process includes:

[0012] Grind the screened construction waste to obtain recycled micro powder;

[0013] Aggregate, recycled micro powder, fly ash, cement, water and activator are mixed and stirred according to the preset material ratio to obtain the target material.

[0014] Further, if the concave engraving area ratio of the preset component image is greater than the preset concave engraving area ratio, the preset component image is divided into regions to obtain a plurality of sub-image regions;

[0015] The concave pattern coincidence and the molding difficulty coefficient corresponding to each sub-image area are detected, and a similar area set is determined according to the concave pattern coincidence and the molding difficulty coefficient corresponding to each sub-image area.

[0016] Furthermore, if the concave area ratio of the preset component image is less than or equal to the preset concave area ratio, the ratio of a type of concave pattern of the preset component image is detected, and the area division method of the concave area is determined according to the ratio of a type of concave pattern, wherein:

[0017] If the proportion of one type of intaglio pattern is greater than the proportion of a preset type of intaglio pattern, a number of key detection areas are determined according to the difference in intaglio depth;

[0018] If the proportion of one type of intaglio patterns is less than or equal to the proportion of a preset type of intaglio patterns, the preset component image is divided according to the interval distance corresponding to the intaglio patterns to obtain the key detection area;

[0019] The first type of intaglio pattern is an intaglio area pattern with an intaglio depth greater than a preset intaglio depth.

[0020] Furthermore, the quality inspection method is determined according to whether the preset component image of the target molded component has a sub-image area.

[0021] If a sub-image area exists in the preset component image of the target molded component, it is determined that a radiographic inspection is performed on the target molded component, and a quality analysis strategy is determined according to the proportion of the concave engraved area;

[0022] If the sub-image area does not exist in the preset component image of the target molded component, it is determined that ultrasonic testing is performed on the target molded component.

[0023] Further, under the first detection condition, radiation detection is performed on the corresponding component parts of each similar area set respectively, wherein the image quality coefficient of the radiation detection image of the corresponding component part of a single similar area set is detected, and if the image quality coefficient is less than or equal to a preset image quality coefficient, the detection tube current for detecting the similar area set is increased and adjusted according to the image quality coefficient;

[0024] The increase value of the detection tube current is negatively correlated with the image quality coefficient;

[0025] The image quality coefficient is determined according to a contrast reference value and a clarity reference value of the radiographic detection image;

[0026] The first detection condition is that the proportion of the concave engraved area of ​​the preset component image is greater than the preset concave engraved area proportion.

[0027] Further, under the second detection condition, the corresponding component parts of each key detection area are respectively subjected to ray detection, and the richness of the imaging angles for detecting the corresponding component parts is set according to the division parameters of each key detection area, wherein:

[0028] If the division parameter of the key detection area is the concave engraving depth difference value, the imaging angle richness is determined according to the average concave engraving depth reference value of the key detection area;

[0029] If the division parameter of the key detection area is the interval distance, the imaging angle richness is determined according to the average interval distance of the key detection area;

[0030] The second detection condition is that the proportion of the concave engraved area of ​​the preset component image is greater than the preset concave engraved area proportion.

[0031] Furthermore, the overlap coefficient between the abnormal quality area and the concave area of ​​the target molded component is detected, and the preparation adjustment strategy of the target molded component is determined according to the overlap coefficient. The preparation adjustment strategy is to increase the preparation grinding time or the activator dosage.

[0032] Furthermore, if the overlap coefficient between the quality abnormal area and the concave engraved area is greater than the preset overlap coefficient, the preparation grinding time of the regenerated micro powder is increased and adjusted according to the proportion of the quality abnormal area;

[0033] The increase in the preparation grinding time is positively correlated with the proportion of quality abnormality areas.

[0034] Furthermore, if the overlap coefficient between the mass abnormal area and the concave engraved area is less than or equal to the preset overlap coefficient, the amount of the activator is increased and adjusted according to the proportion of the mass abnormal area;

[0035] The increase in the amount of the stimulant is positively correlated with the proportion of the quality abnormality area.

[0036] Compared with the prior art, the beneficial effect of the present invention lies in that the technical solution of the present invention analyzes the preset component image of the target molded component to obtain a set of similar areas or key inspection areas, and determines a targeted quality inspection method based on this. The present invention improves the accuracy of the quality inspection results of the target molded component, thereby improving the effectiveness of the adjustment method of the preparation process of the target molded component.

[0037] Furthermore, in the present invention, a regional analysis method of a preset component image is determined according to the proportion of the concave area of ​​the preset component image of the target molded component. If the proportion of the concave area is greater than the preset concave area proportion, a similar area set is determined by the concave pattern overlap and the molding difficulty coefficient. Subsequently, the same quality inspection method and inspection parameters are adopted for a single similar area set, thereby improving the quality inspection efficiency for the target molded component while ensuring the accuracy of the quality inspection results.

[0038] Furthermore, in the present invention, when the proportion of the concave area is less than or equal to the preset proportion of the concave area, the area division method is determined according to the proportion of a type of concave pattern; if the proportion of a type of concave pattern is greater than the preset proportion of a type of concave pattern, the key detection area is obtained by dividing according to the concave depth difference value to avoid the large difference in thickness of the target molded component in a single key detection area affecting the accuracy of the quality inspection result of this part of the target molded component; if the proportion of a type of concave pattern is less than or equal to the preset proportion of a type of concave pattern, the concave patterns are divided according to the spacing distance between each other to ensure the targeted quality inspection method of different subsequent areas.

[0039] Furthermore, the present invention determines the preparation adjustment strategy of the target molded component according to the overlap coefficient between the quality abnormality area and the concave engraving area, and determines the targeted adjustment strategy in combination with the previous concave engraving area analysis and quality inspection results, so that the adjustment strategy for the target molded component is more in line with the actual situation. The present invention improves the effectiveness of the adjustment method for the preparation process of the target molded component. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] See also Figures 1 to 4 As shown, an embodiment of the present invention provides a method for producing decorative materials from construction waste, comprising:

[0049] Using a preset production process to prepare a target material including recycled micropowder, and using the target material to manufacture a target molded component;

[0050] Acquire a preset component image of a target molded component;

[0051] Determine a regional analysis method according to the proportion of the concave area of ​​the preset component image, the regional analysis method is to determine a set of similar areas according to the overlap of the concave patterns between the sub-image areas and the molding difficulty coefficient, or determine a regional division method of the concave area according to the proportion of a type of concave pattern to obtain a key detection area;

[0053] The preparation adjustment strategy of the target molded component is selected according to the overlap coefficient between the quality abnormal area and the concave area of ​​the target molded component. The preparation adjustment strategy is to adjust the preparation grinding time or the activator dosage during the preparation of the target material.

[0054] Among them, the application scenario of the present invention is to prepare an assembled wall with an intaglio pattern based on construction waste. The assembled wall is only provided with one intaglio surface, which is a side surface of the assembled wall with an intaglio pattern. The intaglio pattern is an area of ​​arbitrary shape and smaller in area than any sub-image area. The thickness of the target molding component corresponding to the intaglio pattern is less than the wall thickness of the target molding component. The intaglio surface is divided into several rectangular areas of the same area. If a rectangular area includes at least one complete intaglio image, the rectangular area is a sub-image area. If there is no complete intaglio image in a rectangular area, the rectangular area is an invalid area. The intaglio area is a collection of sub-image areas. The target molding component in the present invention is a prepared assembled wall. The depth of each intaglio pattern in the present invention is less than the thickness of the target molding component, and the thickness is the wall thickness of the target molding component, which will not be elaborated here.

[0055] In the present invention, several preparation history records are correspondingly provided, and any one of the preparation history records the concave engraving pattern coincidence, concave engraving area proportion, difficulty coefficient difference value, one type of concave engraving pattern proportion, concave engraving depth difference value, spacing distance, concave engraving depth, image quality coefficient and coincidence coefficient in at least one historical manufacturing process of producing decorative and finishing materials from construction waste, and each preparation history record corresponds to a qualified mark, which records whether the accuracy of the quality inspection results of the target molded component meets user requirements.

[0056] Specifically, the preset production process includes:

[0057] Grind the screened construction waste to obtain recycled micro powder;

[0058] Aggregate, recycled micro powder, fly ash, cement, water and activator are mixed and stirred according to the preset material ratio to obtain the target material.

[0059] The preparation process of the regenerated micro-powder includes crushing and grinding the selected construction waste according to the preparation and grinding time, and heat-treating the crushed and ground construction waste to obtain the regenerated micro-powder. The construction waste used to prepare the regenerated micro-powder includes brick waste and concrete waste. The heat treatment is to dry the target raw material that has been crushed and ground. The heat treatment process uses a dryer to heat the crushed and ground construction waste using a heat source to evaporate the water therein, and provide a preset material ratio of a target material. The preset material ratio is: aggregate 1000-1200kg / m 3 , Regenerated micro powder 50-100kg / m 3 , fly ash 50-150kg / m 3 , cement 300-400kg / m 3 , water 150-200kg / m3 , the amount of activator added is 2% of the mass of the target material, the obtained target material is poured into the prefabricated mold of the target molded component, and the target molded component is obtained by adopting the preset curing process. The preset curing process includes: after the concrete is poured, the surface is smoothed and covered with a wet cloth or plastic film to keep it moist, and the prefabricated parts are sent to the steam curing room. The hydration reaction of the concrete is accelerated by controlling the temperature and humidity to achieve the designed strength. After the steam curing is completed, the prefabricated parts are placed in a well-ventilated environment for natural hardening. Users can set the preset material ratio, prefabricated mold and preset curing process according to actual preparation needs. This is easy for technicians in this field to understand and will not be repeated here.

[0060] Specifically, if the concave engraving area ratio of the preset component image is greater than the preset concave engraving area ratio, the preset component image is divided into regions to obtain a plurality of sub-image regions;

[0061] The concave pattern coincidence and the molding difficulty coefficient corresponding to each sub-image area are detected, and a similar area set is determined according to the concave pattern coincidence and the molding difficulty coefficient corresponding to each sub-image area.

[0062] Among them, the concave area ratio = (the sum of the horizontal areas of each concave pattern / the area of ​​the side surface of the target molded component with the concave pattern) × 100%. The value of the preset concave area ratio can be determined by the user according to the actual working scenario. For example, the user can set it according to the preparation history record. The higher the user's requirement for the accuracy of the quality inspection result, the smaller the value of the preset concave area ratio. A method for determining the value of the preset concave area ratio is provided, and the preparation history record of a set of similar areas determined according to the overlap of the concave patterns is recorded as a regional reference record. The minimum value of the concave area ratio in the regional reference record that meets the user's requirement for the accuracy of the quality inspection result is recorded as the preset concave area ratio. A value of the preset concave area ratio is provided, and the value of the preset concave area ratio is 40%.

[0063] The concave pattern overlap degree = the number of overlapping concave patterns / the maximum value of the number of regional patterns of the two sub-image areas. For a single concave pattern, if there is a concave pattern in the other sub-image area that is consistent with the shape, size and depth of the concave pattern, then the concave pattern is determined to be the overlapping concave pattern of the two sub-image areas, and the number of concave patterns in each sub-image area is recorded as the number of regional patterns of the corresponding sub-image area. The user can determine the value of the preset pattern overlap degree according to the actual working scene. For example, the user can set it according to the preparation history record. The user has a certain control over the quality inspection results. The higher the accuracy requirement, the greater the value of the preset pattern coincidence. A value of the preset pattern coincidence is provided. The minimum value of the concave pattern coincidence between each sub-image area in each similar area set in the area reference record that meets the user's accuracy requirement for the quality inspection result is recorded as the preset pattern coincidence. When the similar area set is determined only based on the concave pattern coincidence, the concave pattern coincidence between any two sub-image areas in any similar area set is greater than the preset pattern coincidence, and for any sub-image area, it and the sub-image area corresponding to the maximum concave pattern coincidence are in the same similar area set;

[0064] If it is not possible to determine that each sub-image area in the preset component image has a similar area set based on the concave pattern overlap, that is, there is at least one sub-image area whose concave pattern overlap with other sub-image areas is less than or equal to the preset pattern overlap, then the similar area set is determined based on the molding difficulty coefficient of each sub-image area, and the difficulty coefficient difference value of any similar area set obtained is less than the preset coefficient difference value. For a single sub-image area, the molding difficulty coefficient is the sum of the product of the number of key features of each category contained in the sub-image area and the key coefficient of the key feature of the corresponding category. The categories of abnormal features include but are not limited to fillets with a radius of less than 5 cm and corners with an angle of less than 30°. Users can set key features and key coefficients of key features of each category according to actual working scenarios, which will not be elaborated here. For a single similar area set, the difficulty coefficient difference value is the difference between the maximum value of the molding difficulty coefficient of each sub-image area in the similar area set and the minimum value of the molding difficulty coefficient. The user can determine the value of the preset coefficient difference value according to the actual working scenario. For example, the user can set it according to the preparation history record, and record the preparation history record of the similar area set determined according to the molding difficulty coefficient as the coefficient reference record, and record the average value of the difficulty coefficient difference values ​​of each similar area set in the coefficient reference record that meets the user's requirements for the accuracy of the quality inspection results as the preset coefficient difference value; there are several similar area sets in the preset component image, and the number of similar area sets is set according to the actual working scenario. There are at least two sub-image areas in any similar area set, and any sub-image area corresponds to a similar area set.

[0065] Specifically, if the concave area ratio of the preset component image is less than or equal to the preset concave area ratio, the ratio of a type of concave pattern of the preset component image is detected, and the area division method of the concave area is determined according to the ratio of the type of concave pattern, wherein:

[0066] If the proportion of one type of intaglio pattern is greater than the proportion of a preset type of intaglio pattern, the key detection area is determined according to the difference value of the intaglio depth;

[0067] If the proportion of one type of intaglio patterns is less than or equal to the proportion of a preset type of intaglio patterns, the preset component image is divided according to the interval distance corresponding to the intaglio patterns to obtain the key detection area;

[0068] The first type of intaglio pattern is an intaglio area pattern with an intaglio depth greater than a preset intaglio depth.

[0069] Among them, the proportion of a type of intaglio pattern = the number of a type of intaglio patterns in a preset component image / the number of intaglio patterns in a preset component image. The user can determine the value of the proportion of a type of intaglio pattern according to the actual working scenario. The higher the accuracy requirement of the quality inspection result by the user, the smaller the value of the proportion of a type of intaglio pattern is. A value of the proportion of a type of intaglio pattern is provided, and the value of the proportion of a type of intaglio pattern is 0.5;

[0070] If the proportion of one type of concave patterns is greater than the preset proportion of one type of concave patterns, the concave depth difference values ​​between the concave patterns are detected, and a number of key detection areas are determined according to the concave depth difference values. For a single key detection area, the concave depth difference value of each concave pattern in the key detection area is less than the preset concave depth difference value, and the concave depth difference value = the sum of the absolute values ​​of the differences between the concave depths of each concave pattern in the key detection area and the average concave depth / the number of concave patterns in the key detection area, and the average concave depth is the average value of the concave depths of each concave pattern in the key detection area. The value of the preset concave depth difference value can be determined by the user according to the actual working scene. The higher the user's requirements for the accuracy of the quality inspection result, the smaller the value of the preset concave depth difference value is. A value of the preset concave depth difference value is provided, and the value of the preset concave depth difference value is 5% of the thickness of the target molded component.

[0071] If the proportion of one type of intaglio patterns is less than or equal to the proportion of a preset type of intaglio patterns, the interval distance between each intaglio pattern is detected, and the preset component image is divided according to the interval distance between each intaglio pattern to obtain a number of key detection areas. For a single key detection area, the interval distance between any two adjacent intaglio patterns in the key detection area is less than the preset interval distance. If the line connecting the associated points of the two intaglio patterns does not pass through the area of ​​other intaglio patterns, the two intaglio patterns are determined to be adjacent intaglio patterns. The interval distance between the two adjacent intaglio patterns is the length of the line segment obtained by connecting the corresponding two associated points. The associated points of the two intaglio patterns are the two points on the edges of the two intaglio patterns that are closest to each other. The user can set the value of the preset interval distance according to actual needs and historical records. The higher the user's requirements for the accuracy of the quality inspection result, the smaller the value of the preset interval distance. A value of the preset interval distance is provided, and the value of the preset interval distance is 5% of the length of the short side of the intaglio surface. The number of key detection areas in the present invention is determined according to the actual working scene, and not all areas in the preset component image correspond to key detection areas.

[0072] For a single concave engraving pattern, its concave engraving depth is the distance between the deepest point of the concave engraving pattern and the surface of the concave engraving surface. The value of the preset concave engraving depth can be determined by the user according to the actual working scenario. The higher the user's requirements for the accuracy of the quality inspection results, the smaller the value of the preset concave engraving depth. A preset concave engraving depth value is provided, and the preset concave engraving depth value is 50% of the target molded component.

[0073] Specifically, the quality inspection method is determined according to whether the preset component image of the target molded component has a sub-image area.

[0074] If a sub-image area exists in the preset component image of the target molded component, it is determined that a radiographic inspection is performed on the target molded component, and a quality analysis strategy is determined according to the proportion of the concave engraved area;

[0075] If the sub-image area does not exist in the preset component image of the target molded component, it is determined that ultrasonic testing is performed on the target molded component.

[0076] Among them, the ray detection is X-ray imaging detection, and the X-rays penetrate the target molded components. Due to the differences in the internal structures of the target molded components, the X-rays will be absorbed and scattered to varying degrees during the penetration process. These absorbed and scattered X-rays are received by a digital flat-panel detector and converted into electrical signals, which are then processed by a computer to ultimately form a digital image. The present invention does not make specific restrictions on the equipment used for ultrasonic detection and ray detection. Users can make adaptive settings based on actual scenarios. How to perform ultrasonic detection and X-ray imaging detection on the target molded components is easy for those skilled in the art to understand and will not be elaborated here.

[0077] Specifically, under the first detection condition, radiation detection is performed on the corresponding component parts of each similar area set respectively, wherein the image quality coefficient of the radiation detection image of the corresponding component part of a single similar area set is detected, and if the image quality coefficient is less than or equal to the preset image quality coefficient, the detection tube current for detecting the similar area set is increased and adjusted according to the image quality coefficient;

[0078] The increase value of the detection tube current is negatively correlated with the image quality coefficient;

[0079] The image quality coefficient is determined according to a contrast reference value and a clarity reference value of the radiographic detection image;

[0080] The first detection condition is that the proportion of the concave engraved area of ​​the preset component image is greater than the preset concave engraved area proportion.

[0081] Among them, the corresponding component part of each similar area set is the target formed component of the corresponding part of the sub-image area of ​​each similar area set, and the image quality coefficient is the natural logarithm of the product of the contrast reference value and the clarity reference value. The contrast reference value is the absolute value of the difference between the grayscale values ​​of the defect area and the background area obtained by detection, and the background area is the radiation detection image excluding the defect area. The clarity reference value is the slope of the image grayscale change curve within the penumbra width; the user can determine the value of the preset image quality coefficient according to the actual working scene. For example, the user can set it according to the preparation history record. The higher the user's accuracy requirement for the quality detection result, the larger the value of the preset image quality coefficient. A method for determining the value of the preset image quality is provided, and the average value of the image quality coefficient of each radiation detection image in the preparation history record that meets the user's accuracy requirement for the corresponding quality detection result is recorded as the preset image quality coefficient. If the image quality coefficient is greater than the preset image quality coefficient, no adjustment is made for the current detection tube current. The detection tube current is the number of electrons transferred from the cathode to the anode per unit time. The detection tube current determines the luminous flux of the X-ray. How to adjust the detection tube current is easy to understand for those skilled in the art and will not be repeated here.

[0082] Specifically, under the second detection condition, the corresponding component parts of each key detection area are respectively subjected to ray detection, and the richness of the imaging angles for detecting the corresponding component parts is set according to the division parameters of each key detection area, wherein:

[0083] If the division parameter of the key detection area is the concave engraving depth difference value, the imaging angle richness is determined according to the average concave engraving depth reference value of the key detection area;

[0084] If the division parameter of the key detection area is the interval distance, the imaging angle richness is determined according to the average interval distance of the key detection area;

[0085] The second detection condition is that the proportion of the concave engraved area of ​​the preset component image is greater than the preset concave engraved area proportion.

[0086] The imaging angle richness is positively correlated with the average concave engraving depth reference value, and the imaging angle richness is negatively correlated with the average spacing distance; the corresponding component part of each key detection area is the target molding component of the corresponding part of the sub-image area of ​​each key detection area, and the division parameter includes the concave engraving depth difference value and the spacing distance between each concave engraving pattern. If the key detection area is determined according to the concave engraving depth difference value, the division parameter of the key detection area is determined to be the concave engraving depth difference value; if the key detection area is determined according to the spacing distance between each concave engraving pattern, the division parameter of the key detection area is determined to be the spacing distance between each concave engraving pattern;

[0087] The imaging angle richness is the number of different ray projection angles on the surface of the target molded component when performing ray detection on the key detection area, the average concave engraving depth reference value is the average value of the concave engraving depths of each concave engraving pattern in the key detection area, and the average spacing distance is the average value of the spacing distances between adjacent concave engraving patterns in the key detection area. By projecting X-rays from different angles and performing multiple detections and superpositions, the information loss or ambiguity of the detection results caused by uneven thickness can be compensated, thereby improving the comprehensiveness and reliability of the detection; ultrasonic detection is used for the target molded component outside the corresponding part of the key detection area.

[0088] Specifically, the overlap coefficient between the abnormal quality area and the concave area of ​​the target molded component is detected, and the preparation adjustment strategy of the target molded component is determined according to the overlap coefficient. The preparation adjustment strategy is to increase the preparation grinding time or the activator dosage.

[0089] Among them, the overlap coefficient between the abnormal quality area and the concave area of ​​the target molded component = the area of ​​the abnormal overlapping area / the area of ​​the abnormal quality area, the abnormal overlapping area is the overlapping area between the abnormal quality area and the concave area of ​​the target molded component, the abnormal quality area is the area with quality defects after the quality inspection, that is, after the ultrasonic inspection or the X-ray inspection, the quality defects of the target molded component in the present invention include but are not limited to the existence of cracks and the component strength does not meet the user requirements. How to judge whether the quality of the corresponding part of the component in each image area meets the user requirements based on the ultrasonic inspection results and the X-ray inspection results is easy for technical personnel in this field to understand and will not be elaborated here.

[0090] Specifically, if the overlap coefficient between the quality abnormal area and the concave engraved area is greater than the preset overlap coefficient, the preparation and grinding time of the regenerated micro powder is increased and adjusted according to the proportion of the quality abnormal area;

[0091] The increase in the preparation grinding time is positively correlated with the proportion of quality abnormality areas.

[0092] The user can determine the value of the preset coincidence coefficient according to the actual working scenario. For example, the user can set it according to the preparation history record, and provide a method for determining the value of the preset coincidence coefficient. The preparation history record in which the quality of the target molded component meets the user's needs by adjusting the activator dosage is recorded as a reference record, and the maximum value of the coincidence coefficient between the quality abnormal area and the concave engraving area in the reference record is recorded as the preset coincidence coefficient.

[0093] The preparation grinding time is the grinding time for construction waste in the process of preparing recycled micropowder. Since the quality abnormality areas are mainly concentrated in the concave areas, it is necessary to adjust the fluidity of concrete in the preparation process. By increasing the preparation grinding time of the recycled micropowder, the fluidity can be effectively improved and the quality of the target molded components can be improved.

[0094] Specifically, if the overlap coefficient between the mass abnormal area and the concave engraving area is less than or equal to the preset overlap coefficient, the amount of the activator is increased and adjusted according to the proportion of the mass abnormal area;

[0095] The increase in the amount of the stimulant is positively correlated with the proportion of the quality abnormality area.

[0096] Among them, the activator dosage is the amount of activator added during the preparation of the target material. The activator used in the present invention is quicklime. It can be seen from the fact that the overlap coefficient between the quality abnormality area and the concave area is less than or equal to the preset overlap coefficient that the cause of the defects in the target molded component is not related to the fluidity of the concrete, so it is necessary to increase the dosage of quicklime to improve the compressive strength of the target molded component.

[0100] Note: The defective rate A in Table 1 is the defective rate of a single batch prepared using the above-mentioned manufacturing method, and the defective rate B is the defective rate of a single batch prepared without using the above-mentioned manufacturing method. The initial manufacturing parameters and the curing process of the two preparation processes in the same embodiment are consistent. The initial manufacturing parameters are the preset material ratio and the preparation grinding time. The number of target molded components prepared in each batch is 500.

[0101] According to Examples 1 to 4 in Table 1, when there is an abnormal quality area and the overlap coefficient is large, after adjusting the preparation grinding time according to the preparation adjustment strategy in the present invention, the defective rate of the prepared target molded component is effectively improved. According to Examples 5 to 8 in Table 1, when there is an abnormal quality area and the overlap coefficient is small, after adjusting the stimulator dosage according to the preparation adjustment strategy in the present invention, the defective rate of the prepared target molded component is effectively improved, which proves that the above preparation method improves the accuracy of the quality inspection results of the target molded component and the effectiveness of the adjustment of the preparation process.
