Description

Technical Field

[0001] The invention relates to the technical field of ceramics, and in particular to a method for testing the long-term effectiveness of anti-skid ceramic tiles. Background Art

[0002] Architectural ceramic tiles are mainly used for walls and floors of home spaces, playing a decorative role of easy cleaning and beautiful appearance. However, with the improvement of people's living standards, consumers have put forward higher requirements for the functions of ceramic tiles, and some decorative spaces require that the ceramic tiles on the floor must have higher anti-slip properties.

[0003] There are many types of anti-slip tiles in the market. According to the process, they can be divided into mold anti-slip tiles, glaze anti-slip tiles, dry granule anti-slip tiles and post-processed anti-slip tiles. In order to improve the anti-slip performance of the product, manufacturers often combine a variety of technologies to improve the anti-slip performance of ceramic tiles, and improve the anti-slip performance of ceramic tiles from multiple angles and aspects. For example, the uneven mold effect is combined with anti-slip glaze and anti-slip dry particles. Some also use anti-slip glaze combined with post-processing anti-slip liquid, concave and convex molds combined with anti-slip liquid, and mold surface combined with post-processing grooves.

[0004] No matter what kind of technology is used to improve the anti-slip function of ceramic tiles or improve the comfort of the body, once they are used, they will face a practical problem, that is, after a period of use, the surface of the anti-slip ceramic tiles will have a certain degree of wear, especially when used in areas such as entrances and exits of public places, the wear phenomenon is more serious. These anti-slip ceramic tile products that have been used for a period of time will have a certain impact on their anti-slip function. Even some ceramic tiles with anti-slip technology have high original anti-slip safety performance, but after a short period of application and wear, the anti-slip function disappears completely, which seriously affects consumers' trust in anti-slip ceramic tiles and also causes physical or mental harm to consumers. This has affected the promotion and use of anti-slip ceramic tiles to a certain extent, and also caused confusion for consumers in choosing what kind of anti-slip ceramic tiles.

[0005] At present, in the ceramic industry, the performance indicators of anti-slip ceramic tiles are all obtained after anti-slip tests on unworn anti-slip ceramic tiles, and the performance of anti-slip ceramic tiles after wear has not been tested, and thus the performance of anti-slip ceramic tiles after wear cannot be explained, which is not conducive to the improvement and rational use of anti-slip ceramic tiles.

DETAILED DESCRIPTION

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0049] After anti-skid ceramic tiles have been used in actual spaces for a period of time, it is very important to evaluate and test whether they can continue to maintain their anti-skid performance, or how to determine their anti-skid safety. At present, the building ceramics industry does not have the technology and method to quickly evaluate the long-term anti-skid performance of ceramic tiles after use. The wear resistance grade and wear volume currently used by ceramic tiles cannot simulate the actual application phenomenon well. The grade determination is closely related to the color of the product. The wear material used in the wear volume does not conform to the actual life, and the surface part of the ceramic tile after wear detection cannot be accurately tested by the existing anti-skid detection method to determine the changes before and after.

[0050] In view of the above-mentioned deficiencies in the existing technology, there is an urgent need for an evaluation method for quickly testing the long-term effectiveness of anti-slip ceramic tiles after use, so as to facilitate manufacturers to determine the long-term effectiveness of the anti-slip process, so as to produce the most suitable products to guide the applicable places and serve consumers. It can also guide the industry and standardize the classification of the process effects of anti-slip ceramic tiles, so as to distinguish which processes of anti-slip ceramic tiles have long-term effectiveness and the long-term effectiveness level evaluation.

[0051] The present invention provides a method for testing the long-term performance of anti-skid ceramic tiles. Figure 1 As shown, the long-term testing method of anti-slip ceramic tiles includes:

[0052] Step S100: performing a wear test on the test surface of the anti-slip ceramic tile to be tested.

[0053] Specifically, Figure 2 As shown, clean the anti-skid tile sample with known initial pendulum value and wait for the surface to dry; place the dried anti-skid tile sample with the wear surface facing up in the sample placement area of ​​the accelerated wear device; set the number of wear times of reciprocating linear wear motion according to the counterweight pressure standard of the accelerated wear device; start the accelerated wear device until the number of wear times reaches the set number, and the device automatically stops moving. The accelerated wear device is equipped with a counterweight, the purpose of which is to increase the positive pressure between the wear material and the surface of the ceramic tile to be tested, so as to improve and accelerate the wear effect.

[0054] In one embodiment, when performing the wear test, the wear material is selected as a Scottish Bright ultra-fine wiping pad, the wear weight is 1 kg, the number of reciprocating times is 5000 times, the wear area is 100 mm × 300 mm, the grinding block size is 50 mm × 100 mm, and the anti-slip performance test area after wear is the 72.6 mm × 126 mm area in the middle of the wear area. Figure 3 As shown. Reciprocating linear wear motion means that the slider with wear material installed makes a reciprocating motion on the test surface, which is counted as 1 time; the counter can be set to the number of reciprocating times required for reciprocating wear, and the counter counts each time the reciprocating motion is reached until the set value is reached, and the reciprocating wear motion stops.

[0055] The existing method for determining the wear resistance of anti-slip floor tiles is to use two standard tests for glazed and unglazed tiles, whose wear mechanisms and the criteria used to evaluate the results are significantly different. This is not conducive to comparing the performance of glazed and unglazed products, even though the anti-slip floor tiles of these two processes may be used in the same areas. In addition, the current test methods used to evaluate the wear resistance of ceramic floor tiles are not suitable for evaluating the long-term use of products. There are several main reasons for this:

[0056] First, the mechanisms and materials for producing wear are different. Glazed tiles use metal balls of 4 different sizes, 1mm, 2mm, 3mm, and 5mm in diameter, and corundum abrasives with a particle size of F80, while unglazed tiles use steel wheels. This has nothing to do with the actual use conditions. The impact of different experimental test methods on the wear resistance of ceramic floor tiles is significantly greater than the impact of pedestrians on ceramic floor tiles.

[0057] Second, the type of abrasive used is corundum, which is much harder than the abrasive particles that ceramic floor tiles are likely to come into contact with in actual use scenarios.

[0058] Third, the evaluation criteria of the results include: glazed tiles are evaluated by changes in wear, color, and gloss, while unglazed tiles are evaluated by volume loss, which is unrelated to the surface changes caused by wear. In most cases, surface changes are manifested as changes in surface roughness and surface gloss. However, for ceramic tiles used in building spaces with large flow of people or heavy traffic, it is not enough to judge whether the selected ceramic tiles are suitable for anti-skid and wear resistance based solely on the changes in surface roughness and surface gloss caused by wear. At present, there is a lack of standards and methods that can test and prove that they are consistent with the required anti-skid and wear resistance levels. Therefore, the embodiments of the present application have formulated a long-term standard equivalent to the wear resistance of anti-skid floor tiles. By reproducing the actual wear mechanism, the long-term wear resistance of anti-skid ceramic floor tiles is evaluated, thereby ensuring the compatibility and service requirements of the product, and at the same time preventing unnecessary accidents caused by the selection of unsuitable anti-skid ceramic floor tiles for the use space.

[0059] The wear material selected in the embodiment of the present application is a Scottish Bright ultra-fine wiping pad, which is a material similar to the material of rubber shoes in daily life, facilitates long-term wear testing, and improves the authenticity of the wear test.

[0060] In one embodiment of the present application, before performing a wear test on the test surface of the anti-slip ceramic tile to be tested, it also includes: placing the test surface of the anti-slip ceramic tile to be tested facing upward and horizontally on a test bench; performing an anti-slip performance test on the test surface using a pendulum method to obtain an initial pendulum value, or performing an anti-slip performance test on the test surface using a sliding friction method to obtain an initial sliding friction value.

[0061] In the embodiment of the present application, the test surface of the anti-slip tile is first cleaned, and the test surface of the anti-slip ceramic tile to be tested is placed horizontally on the test bench with the test surface facing upward, and the pendulum method or sliding friction method is selected, and the initial pendulum value or initial sliding friction value of the anti-slip ceramic tile sample is tested according to its test standard. Figure 4 As shown, Figure 4 This is a standard table for determining the anti-slip grade using the pendulum method (wet state).

[0062] Specifically, the surface of anti-skid ceramic tiles is usually rough and prone to dust, foreign particles and other pollutants. Therefore, the test surface of the anti-skid tiles needs to be cleaned. In addition, the surface of the ceramic tiles to be tested must be in a horizontal state. If the test surface is tilted at a certain angle during the test, its actual anti-skid performance will be affected. Therefore, testing in a horizontal state is convenient for reducing test errors.

[0063] There are many methods and principles for anti-slip testing, such as the maximum static friction method, sliding friction method, pendulum method, slope critical angle method, etc. The maximum static friction method cannot properly reflect the state of relative motion between the human body and the ground during movement. The sliding friction method is that the slider slides at a uniform speed on the test surface, which is also inconsistent with the actual walking state in life. The slope critical angle method can reflect the state of a person's toes touching the ground during rapid movement, but there are many influencing factors and the error is large.

[0064] The pendulum method can be preferably used in the example of the present application to test the anti-slip performance of the surface of anti-slip ceramic tiles, because the 4S rubber material used in the pendulum method is close to the material of the sole, has a certain hardness and elasticity, and the pendulum method well simulates the movement state of a person's actual slow walking, in which the heel touches the ground first, and can better simulate and reflect the actual situation.

[0065] Specifically, the anti-skid bricks tested by the pendulum method mainly adopt the principle of energy conversion. From the initial zero speed, after the pendulum makes a circular motion, the potential energy is converted into kinetic energy with a certain speed. When the rubber sheet on the pendulum just contacts the surface of the anti-skid brick, it will continue to slide over a distance on the surface of the ceramic brick due to inertia, and energy loss will occur at this time. If other negligible factors such as air resistance are excluded, this energy loss is the work done by the rubber after sliding over the surface of the anti-skid brick for a distance, that is, the work done by friction resistance. The pendulum method is relatively more scientific in characterizing the anti-friction ability of the surface of an object, and it must be noted that the surface tested by the pendulum method must be a plane. The flatter the surface, the more accurate the data detected. The uneven surface means that the data is not accurate enough. For example, the mold surface with large undulations uses the same anti-skid process and glaze, and the data measured is different from that of a flat surface. Anti-skid products with large undulations are not suitable for testing by the pendulum method. The state of the pendulum rubber of the pendulum method when it just contacts the surface to be tested well simulates the state of a person's heel landing first when walking slowly and relaxing in life. When people walk slowly, if the surface they touch is not anti-slip enough, they are prone to slipping and falling accidents. Most of these slow walkers are elderly people.

[0066] The water method test of the critical angle of the slope is to test the tendency of people to slide as the inclination angle increases. The tester will use the toes to force as the angle continues to increase. This method better simulates the state of people walking fast in life, with the toes touching the ground first. However, when people walk or run fast, if the ground they touch is not anti-slip, they are also prone to fall. Most of these people who walk fast are children, young people or people in motion. In addition, there is an oil method test for the critical angle of the slope. During the oil method test, a large area of ​​rubber safety shoes similar to tire surface and high-viscosity engine oil medium are in contact with the ceramic tile surface. There is a certain error in the test of the critical angle of the slope, and the test results are somewhat subjective. The repeatability of the test results is not as high as the pendulum method. For example, there will be a certain difference between the uphill state and the downhill state. The pendulum method is more suitable for relatively flat surfaces. This type of product with a relatively flat surface is more suitable for most external walkways and entrances and exits of the hallway where the most likely pollutant is water. Many people will wear shoes with hard-soled rubber and worn rubber surface patterns, which are more in line with real life scenarios. The critical angle ramp method is more suitable for testing surfaces with large fluctuations. Whether it is the water method under bare feet or the oil method wearing safety rubber shoes, under a certain positive pressure, the sole of the foot has a certain elasticity, which will mesh with the surface with large fluctuations and high roughness, thereby increasing friction and preventing the tendency of relative sliding. Products tested by the slope critical angle oil method are more suitable for commercial kitchens and industrial areas, where people use special rubber shoes and may encounter sticky contaminants. The tooth surface of the safety shoe forms an interlocking mesh with the surface with large fluctuations and high roughness, which can prevent sliding, which is not available in many types of footwear. Therefore, the test results of the slope critical angle oil method may overestimate the resistance obtained by ordinary footwear on certain ceramic tiles or material surfaces. For ceramic tiles or material surfaces with flat surfaces and low roughness, the slope critical angle test method is not suitable.

[0067] The maximum static friction method tests sliding friction. This detection method does not occur in real life. When the human body is moving, the soles of the feet are not in constant contact with the ground. Instead, the risk of slipping may occur when the heels or toes just touch the ground.

[0068] Once the product is laid and used, the pendulum method and the ramp method are used to test the long-term anti-skid effect of the anti-skid ceramic tiles, but none of them are more convenient than the dynamic friction coefficient method. The dynamic sliding friction method can bring the equipment to the site without destroying the tiles, while the pendulum method and the ramp method are not as convenient as the dynamic sliding friction method in principle. Therefore, it is necessary to find an equivalent wear test method to simulate so that the pendulum method can perform equivalent testing. After using a gray abrasive pad with a total weight of 1000g to perform equivalent rapid wear on the tiles, the pendulum method and the dynamic sliding friction method are tested simultaneously. Combined with the previous experiments, the data of the two anti-skid test methods after the wear treatment is 5000 times are obtained.

[0069] The equivalent number of wear times is used to simulate the anti-skid timeliness of ceramic tiles after wear in actual life application scenarios. The data obtained through the equivalent wear of the DCOF value of sliding friction and the PTV value of the pendulum method are matched with the correlation between the two, so as to obtain the anti-skid timeliness of ceramic tiles used in actual scenarios. In this way, the anti-skid property of ceramic tiles in actual application scenarios can be tracked, and the sliding friction coefficient (DCOF) value of sliding friction is collected on site. The pendulum value (PTV) value corresponding to the pendulum method can be obtained by using the laboratory equivalent number of wear times method, which is convenient for subsequent anti-skid long-term detection and judgment of various types of ceramic tiles or materials in actual application scenarios.

[0070] Therefore, based on the actual living conditions and test accuracy, combined with the actual anti-slip effect required by the ceramic tile surface, the PTV value of the pendulum method is preferred to characterize the long-term anti-slip performance of the ceramic tile surface after rapid wear. The accelerated wear equipment includes a reciprocating motion record and a counterweight pressure record on the surface of the wear sample. This type of test method can eliminate the influence of potential subjective human factors.

[0071] In addition, the initial pendulum value refers to the pendulum value tested by the pendulum method when the ceramic tile sample is not worn, which represents the most original anti-slip performance index of the ceramic tile when it leaves the factory.

[0072] The embodiment of the present application can obtain the most original anti-slip performance index of the ceramic tile when it leaves the factory by testing the initial pendulum value.

[0073] In one embodiment of the present application, the anti-slip ceramic tile long-term effectiveness test method further includes: pre-establishing a wear long-term effectiveness grading table; the wear long-term effectiveness grading table includes: a number of long-term effectiveness grade codes, and a wear test threshold range and abrasion times corresponding to the long-term effectiveness grade codes. As shown in Table 1 and Table 2, Table 1 is a wear long-term effectiveness grading table corresponding to the pendulum method test, and Table 2 is a wear long-term effectiveness grading table corresponding to the sliding friction method test. Among them, the MPTV value is the wear pendulum value, and the MCOF value is the sliding friction value.

[0079] The embodiments of the present application can obtain the long-term anti-skid performance of the anti-skid brick after a certain number of wear times through the wear long-term grading table through rapid wear, so that it can be used to determine the places where the anti-skid bricks of this process can be used, and guide enterprises to quickly obtain an equivalent method for the long-term effectiveness of anti-skid ceramic tiles, avoiding safety accidents caused by the weakening or disappearance of the anti-skid effect after the product is used. The method of the embodiments of the present application can be used to predict the anti-skid performance of the anti-skid brick after use in advance, thereby guiding technical and production personnel to make technical adjustments in advance, so as to better guide the technical application and production of anti-skid ceramic tiles and stabilize the quality of the products.

[0080] In one embodiment of the present application, the step S100 specifically includes: under a preset wear pressure, performing a wear test on the test surface of the anti-slip ceramic tile to be tested in the order of the number of wears in the wear long-term grading table from small to large; wherein the long-term grade codes are sorted in the order of the number of wears from small to large.

[0081] like Figure 1 As shown, the anti-slip ceramic tile long-term testing method also includes:

[0082] Step S200: performing an anti-slip performance test on the worn test surface to obtain a wear test value.

[0083] In one embodiment of the present application, the step S200 specifically includes: performing an anti-skid performance test on the worn test surface using a pendulum method to obtain a wear pendulum value; or, performing an anti-skid performance test on the worn test surface using a sliding friction method to obtain a wear sliding friction value.

[0084] The embodiment of the present application cleans the surface of an anti-slip ceramic tile that has been worn a certain number of times, and again uses the pendulum method to measure the pendulum value of the worn surface area to obtain the pendulum value after wear, or, again uses the sliding friction method to test the anti-slip performance of the worn test surface to obtain the wear sliding friction value, and determines the long-term level of the anti-slip performance of the rapid wear anti-slip tiles of this process technology.

[0085] Specifically, the surface after reciprocating wear has been worn to a certain extent. At this time, the middle position of the rapid wear zone can be selected, and the pendulum method can be used to measure the pendulum value after wear. According to the pendulum value standard, if the pendulum value of the ceramic tile surface after 5000 times of rapid reciprocating wear with a weight of 1kg can reach PTV≥35, it means that it still has medium anti-slip performance, and the ceramic tile of this process is judged to have long-term wear and slip resistance. The wear long-term classification table is based on Figure 4 Set it using the standard table.

[0086] like Figure 1 As shown, the anti-slip ceramic tile long-term testing method also includes:

[0087] Step S300: determining the long-term effectiveness level of the anti-slip ceramic tile to be tested according to the wear test value.

[0088] In one embodiment, the pendulum method is used to measure the equivalent wear and anti-skid timeliness of the anti-skid tiles. The anti-skid tiles are made of anti-skid glaze technology, the initial pendulum value is 71, the wear area is 100mm×300mm, the counterweight pressure is 1kg, and the Scottish Bright ultra-fine wiping pad is used as the wear material. After 5000 times of wear, the pendulum value (PTV) of the middle wear area is measured by the pendulum method and is 45. According to the pendulum test standard, it is determined that the anti-skid ceramic tiles of this process have equivalent wear and anti-skid long-term effectiveness.

[0089] In another embodiment, the sliding friction method is used to measure the equivalent wear and slip resistance of anti-skid tiles. The anti-skid tiles are made of anti-skid glaze technology, with an initial sliding friction coefficient of 0.82, a wear area of ​​100mm×300mm, and a counterweight pressure of 1kg; a Scottish Bright ultra-fine wiping pad is used as the wear material. After 5000 wears, the sliding friction coefficient (DCOF) of the middle wear area is tested by the sliding friction method to be 0.63. According to the sliding friction detection and judgment standard, anti-skid tiles with DCOF≥0.42 have higher safety, and it is determined that the anti-skid tiles of this process have equivalent wear and slip resistance. According to the anti-skid detection and anti-skid grade judgment standard of the friction coefficient method, for all business places facing the public, the static friction coefficient of the floor and corridor should be above 0.60, and the slope should be above 0.80. A friction coefficient of <0.4 is a high risk, 0.4≤friction coefficient<0.6 is a medium risk, and a friction coefficient of ≥0.6 is a low risk.

[0090] In one embodiment of the present application, step S300 specifically includes:

[0091] Step S310, searching the wear long-term effectiveness classification table, and determining the target long-term effectiveness grade code and the target wear test threshold range corresponding to the current wear times in the wear long-term effectiveness classification table;

[0092] Step S320a: If the wear test value is within the target wear test threshold range, the target long-term effectiveness grade code and the current wear times are recorded as the long-term effectiveness grade of the anti-slip ceramic tile to be tested.

[0093] For example, as shown in Tables 1 and 2, the number of wear times is 100, 500, 1000, 2000, and 5000, respectively. When performing a wear test, first perform 100 reciprocating wear times, then perform an anti-slip performance test, obtain the test results, and look up the wear long-term grading table to obtain the test threshold range corresponding to the wear number of 100. If the test result is within the test threshold range, stop the wear test, and record the long-term grade code corresponding to the wear number together with the wear number as the long-term level.

[0094] In one embodiment of the present application, after step S310, the following steps are further included:

[0135] In one embodiment of the present application, the accelerated wear device further comprises a linear mechanism fixing frame 600, and a linear mechanism back plate 610 disposed on the linear mechanism fixing frame 600; the X-axis driving mechanism 100 is disposed on the linear mechanism back plate 610.

The X-axis drive mechanism 100 provided in the embodiment of the present application has high transmission efficiency, can reduce energy loss, and improve the overall efficiency of the mechanical equipment.

[0137] In one embodiment of the present application, the Z-axis driving mechanism 200 includes: a motor base 210, a stepper motor 220, a ball screw 230, a screw nut bracket 240 and a rotating mechanism back plate 250.

[0138] Specifically, the stepper motor 220 provides a rotational motion, which is transmitted to the ball screw 230. When the ball screw 230 rotates, the rotational motion of the ball screw 230 is converted into the linear motion of the nut. Therefore, the ball screw 230 realizes the conversion from rotational motion to linear motion, can smoothly perform high-speed forward and reverse transmission, and improves the stability of the accelerated wear device in the Z-axis direction.

[0141] The coupling is a component that connects the motor output shaft and the ball screw 230. Its main function is to transmit the rotational motion of the motor to the ball screw 230, thereby realizing the rotation of the ball screw 230.

The embodiment of the present application combines the two to further improve the overall positioning accuracy of the device. In addition, the linear guide 290 provides a stable support for the ball screw 230, which helps to reduce the vibration and deflection of the screw during the transmission process. Under high speed or high load conditions, the linear guide 290 can maintain good dynamic response and rigidity, ensuring that the movement of the ball screw 230 is smooth and without fluctuations. The linear guide 290 can also withstand part of the axial and radial loads generated by the ball screw 230 during the transmission process, thereby reducing the burden on the screw and extending its service life.

A rotating shaft bearing fixing seat 350 is also provided on the rotating mechanism back plate 250, and a rotating shaft bearing 360 is fixed on the rotating shaft bearing fixing seat 350. The main function of the bearing is to reduce the friction between the rotating parts so that the rotating shaft can rotate more smoothly, thereby reducing energy consumption and improving the operating efficiency of the mechanical equipment. A precision locking nut 370 is also sleeved on the rotating shaft, and the precision locking nut 370 can effectively fix the rotating shaft and bearings and other components to ensure that they will not loosen or fall off during the rotation process, thereby improving the operating safety and reliability of the mechanical equipment.
