[0032] To further illustrate the technical means and effectiveness of the present invention in achieving its intended objectives, the following, in conjunction with the accompanying drawings and preferred embodiments, describes in detail a polyetherester sponge performance testing method and system according to the present invention, including its specific implementation, structure, features, and effectiveness. In the following description, references to "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics of one or more embodiments may be combined in any suitable manner.

[0033] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0034] The following describes in detail a method and system for detecting the performance of a polyetherester sponge provided by the present invention with reference to the accompanying drawings.

[0035] See also Figure 1 , which shows a flow chart of a method for detecting the performance of a polyetherester sponge provided by one embodiment of the present invention, the method comprising the following steps:

[0036] Step S001: Obtain the pressure exerted on the bottom and top surfaces of the polyetherester sponge at each moment during the process of compressing the polyetherester sponge, and record the pressing speed at each moment.

[0037] It should be noted that polyetherester sponge is a new type of sponge composed of synthetic polyetherester molecules. It combines the physical properties of polyester sponge with the advantages of polyetherester sponge, such as hydrolysis resistance. It is primarily used as a flame composite sponge for automotive interiors. To ensure a good riding experience for both the owner and passengers, polyetherester sponge must exhibit good indentation hardness. Therefore, this example proposes a method for testing the indentation hardness of polyetherester sponges.

[0038] Specifically, place the polyetherester sponge on the test chassis in the compression tester, obtain the thickness of the polyetherester sponge when it is not compressed, and preset an initial pressing speed. , so that the top plate in the compression test machine is pressed down to Press the polyetherester sponge at a speed of The specific value of can be set according to the actual situation. This embodiment does not make a hard requirement. The data are described in millimeters per minute, and the pressure data on the bottom and top surfaces of the polyetherester sponge are collected in real time.

[0039] The compression testing machine includes: a detection chassis and a lower pressure top plate, and pressure sensors are installed in both the detection chassis and the lower pressure top plate; the pressure sensor in the detection chassis collects the pressure on the bottom surface of the polyetherester sponge, and the lower pressure top plate collects the pressure on the top surface of the polyetherester sponge.

[0040] Step S002: According to the difference in pressure on the bottom and top surfaces of the polyetherester sponge at each moment, combined with the pressing speed at each moment, the adjustment speed at each moment is obtained; according to the pressing speed at each moment, combined with the adjustment speed at each moment, the pending pressing speed at the next moment of each moment is obtained; according to the pending pressing speed at each moment, the pressing speed at each moment is obtained and the segmented moments are screened out; according to the segmented moments, the process of compressing the polyetherester sponge is divided into several stages; according to the thickness of the polyetherester sponge at the last moment of each stage and the thickness of the polyetherester sponge when it is not compressed, combined with the preset initial pressing speed, the pressing speed at the first moment of the next stage is obtained, and the pressing speed at each moment in each stage is obtained; according to the pressing speed at each moment in each stage, the polyetherester sponge is compressed, and according to the difference in pressure on the bottom and top surfaces of the polyetherester sponge at each moment of the compression process, the ultimate pressure and ultimate thickness of the polyetherester sponge are obtained.

[0041] It should be noted that when testing the indentation hardness of the polyetherester sponge by a compression testing machine, if the pressing speed is too fast, the polyetherester sponge may not stop pressing the top plate in time during the testing process, causing plastic deformation of the polyetherester sponge, resulting in inaccurate detected indentation hardness; but slowing down the pressing speed will seriously affect the detection efficiency of the polyetherester sponge. Therefore, this embodiment gives the pressing top plate a large initial pressing speed, and adjusts the pressing speed in real time according to the pressure on the bottom and top surfaces of the polyetherester sponge during the pressing process, and finally puts the polyetherester sponge in the limit state of elastic deformation, thereby realizing accurate detection of the performance of the polyetherester sponge.

[0042] It should be further explained that when the polyetherester sponge is compressed by pressing down on the top surface, the polyetherester sponge will deform. Due to the influence of the internal structure of the polyetherester sponge, the pressures on the top and bottom surfaces of the polyetherester sponge are different, that is, there is a pressure difference between the top and bottom surfaces of the polyetherester sponge. The greater the pressure difference, the more severe the deformation of the polyetherester sponge. Therefore, in order to prevent the downward pressure from being too fast, which causes plastic deformation of the polyetherester sponge, it is necessary to adjust the downward pressure in real time. At the same time, in order to improve the detection efficiency of the polyetherester sponge, this embodiment also divides the process of compressing the polyetherester sponge into multiple stages. By adjusting the downward pressure at all times in each stage, the performance detection efficiency of the polyetherester sponge can be improved while avoiding plastic deformation of the polyetherester sponge.

[0043] Specifically, at any moment, the adjustment speed at that moment is obtained according to the difference between the pressures exerted on the top and bottom surfaces of the polyetherester sponge at that moment and the downward pressure speed at that moment;

[0044] In one embodiment of the present invention, at any moment, the difference between the pressures on the top and bottom surfaces of the polyetherester sponge at that moment is normalized, and the product of the normalized result and the downward pressure speed at that moment is used as the adjustment speed at that moment; the specific calculation formula is:

[0045]

[0046] Where, Indicates the Adjust the speed at each moment; Indicates the The pressure on the top surface of the polyetherester sponge at each moment; Indicates the The pressure on the bottom surface of the polyetherester sponge at this moment; Indicates the The pressing speed at each moment; Indicates absolute value operation; Represents the normalization function; the normalization object is the All moments before .

[0047] It should be noted that the adjustment speed indicates the degree to which the pressing speed needs to be adjusted; The larger the value is, the more severe the deformation of the polyetherester sponge is, and the more the pressing speed should be reduced; the adjustment speed at each moment is obtained; therefore, the pressing speed at the next moment can be obtained according to the adjustment speed at each moment.

[0048] In one embodiment of the present invention, at any moment, the difference between the pressing speed at that moment and the adjusted speed at that moment is used as the pending pressing speed at the next moment. The specific calculation formula is:

[0049]

[0050] Where, Indicates the The undetermined pressing speed at a moment; Indicates the The pressing speed at each moment; Indicates the Adjust the speed at each moment.

[0051] Furthermore, a speed division threshold is preset , The specific value of can be set according to the actual situation. This embodiment does not make a hard requirement. Millimeters per minute is described. For any moment, when the pressing speed at the moment is greater than When the pressing speed at the moment is less than or equal to When the time is recorded as the segmented time, all the segmented times in the process of compressing the polyetherester sponge are obtained, and the time period between adjacent segmented times is used as each stage of compressing the polyetherester sponge;

[0052] For any stage, the pressing speed at the first moment of the next stage is obtained according to the thickness of the polyetherester sponge at the last moment of the stage, combined with the preset initial pressing speed and the thickness of the polyetherester sponge when it is not compressed;

[0053] In one embodiment of the present invention, for any stage, the degree of compression of the polyetherester sponge is calculated by subtracting the ratio of the thickness of the polyetherester sponge at the last moment of the stage to the thickness of the polyetherester sponge when it is not compressed from 1; and the product of the degree of compression of the polyetherester sponge and the preset initial pressing speed is calculated as the pressing speed at the first moment of the next stage of the stage. The specific calculation formula is:

[0054]

[0055] Where, Indicates the The downward pressure speed at the first moment of each stage; Indicates the preset initial pressing speed; Indicates the The thickness of the polyetherester sponge at the last moment of each stage; Indicates the thickness of the polyetherester sponge when it is not compressed.

[0056] Further, the pressing speed at the first moment of the next stage is obtained to obtain the pressing speed at each moment in each stage; and the polyetherester sponge is compressed according to the pressing speed at each moment in each stage;

[0057] Preset a pressure difference termination threshold , The specific value of can be set according to the actual situation. This embodiment does not make a hard requirement. Newton, when the difference between the pressure on the top and bottom surfaces of the polyetherester sponge is less than When the pressure on the top plate stops, the reading of the pressure sensor in the top plate and the thickness of the polyetherester sponge are recorded, which are respectively recorded as the ultimate pressure and ultimate thickness of the polyetherester sponge.

[0058] It should be noted that, in this embodiment, the process of compressing the polyetherester sponge is divided into several stages to avoid blindly reducing the pressing speed, thereby improving the efficiency of the polyetherester sponge performance test; It indicates the degree to which the polyetherester sponge is compressed. The larger the value of is, the closer the polyetherester sponge is to the elastic deformation limit state. The larger the value, the slower the The downward pressure speed at the first moment of each stage.

[0059] It should be further explained that before the top plate is pressed down to press the polyetherester sponge to the limit state of elastic deformation, the pressure on the top and bottom surfaces of the polyetherester sponge will be inconsistent due to the influence of the internal results of the sponge. Therefore, the more consistent the pressure on the top and bottom surfaces of the polyetherester sponge, the closer the state of the polyetherester sponge is to the limit state of elastic deformation. Therefore, when the difference between the pressure on the top and bottom surfaces of the polyetherester sponge is less than a certain level, it means that the state of the polyetherester sponge is the limit state of elastic deformation. Record the pressure data of the top plate and the thickness of the polyetherester sponge in this state to prepare data for the subsequent calculation of the indentation hardness of the polyetherester sponge.

[0060] At this point, the ultimate pressure and ultimate thickness of the polyetherester sponge were obtained.

[0061] Step S003: Obtaining the indentation hardness of the polyetherester sponge according to the limit pressure and limit thickness at different positions in the polyetherester sponge.

[0062] It should be noted that after obtaining the ultimate pressure and ultimate thickness of the polyetherester sponge through step S002, the indentation hardness of the polyetherester sponge can be obtained based on the ultimate pressure and ultimate thickness of the polyetherester sponge; at the same time, in order to be able to obtain the indentation hardness of the polyetherester sponge more accurately, this embodiment further obtains the indentation hardness of multiple positions of the polyetherester sponge to obtain the overall indentation hardness of the polyetherester sponge.

[0063] Specifically, preset a detection quantity , The specific value of can be set according to the actual situation. This embodiment does not make a hard requirement. Randomly select from polyetherester sponges The position is recorded as the position to be tested, and the indentation hardness of each position to be tested is obtained according to the limit pressure and limit thickness of each position to be tested and the thickness of each position to be tested when not compressed;

[0064] The ultimate pressure of each position to be tested is negatively correlated with the indentation hardness of each position to be tested; the ultimate thickness of each position to be tested is negatively correlated with the indentation hardness of each position to be tested; the thickness of each position to be tested when not compressed is positively correlated with the indentation hardness of each position to be tested;

[0065] In one embodiment of the present invention, the specific calculation formula is:

[0066]

[0067] Where, Indicates the The indentation hardness of the position to be tested; Indicates the The thickness of the measured position when it is not compressed; Indicates the The limit thickness of the position to be measured; Indicates the The ultimate pressure at the position to be tested.

[0068] Furthermore, the average of the indentation hardnesses at all positions of the polyetherester sponge is taken as the indentation hardness of the polyetherester sponge.

[0069] It should be noted that, in this embodiment, the process of compressing the polyetherester sponge is divided into several stages. By adjusting the pressing speed in each stage, the performance detection efficiency of the polyetherester sponge is improved while avoiding plastic deformation of the polyetherester sponge. Furthermore, by calculating the indentation hardness at multiple positions on the polyetherester sponge, the influence of accidental factors is avoided, and the obtained indentation hardness of the polyetherester sponge is made more accurate, ultimately achieving the goal of avoiding plastic deformation of the polyetherester sponge while ensuring the performance detection efficiency of the polyetherester sponge.

When the processor executes the computer program, a polyetherester sponge performance detection method in steps S001 to S003 is implemented.

Any modifications, equivalent substitutions, improvements, etc. made within the principles of the present invention should be included in the scope of protection of the present invention.
