[0002] Soft coated abrasives generally need to test the softness of coated abrasives, especially all kinds of soft abrasive cloths produced by coating with textiles as the substrate. The so-called soft abrasive cloth is based on textiles. Coated abrasives made of adhesives and abrasives have a certain degree of softness, but the current test method for the softness of coated abrasives is not perfect, there are many testing steps, the testing process is quite complicated, and the softness test The result is not accurate enough

Embodiment Construction
[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0021] see figure 1 and figure 2 , the test method for the softness of soft coated abrasives, including the following steps:
[0022] A. Adjust the levelness of the tester a, make the pointer 8 of the pendulum 5 point to the zero position of the dial 6, adjust the position of the sample holder 4 according to the test needs, and fix the sample holder 4;
[0023] B. Clamp the upper end of the sample 3 in the sample holder 4, clamp the sample 3 in the middle of the movable sample holder 4 as far as possible, then adjust the load of the pointer 8, and place the weight 7 in the weight groove on the upper part of the pointer 8 Inside, select the appropriate weight 7 and the added position, so that the pointer 8 is deflected between 2 and 8 on the dial 6; if the selected weight 7 and the added position make the pointer 8 deflect outside the range of 2 to 8,...

The invention relates to a method for testing the softness of a soft coated abrasive tool, which comprises the following steps of: A, adjusting the levelness of a tester, adjusting the position of a sample clamp, and fixing the sample clamp; B, clamping the upper end of the test sample in a test sample clamp, then adjusting the load of a pointer, placing a weight in a weight groove at the upper part of the pointer, selecting a proper weight and an adding position, and enabling the pointer to deflect between 2 and 8 of a dial; B, putting the lower end of the sample to a blade, pressing a startbutton so that the sample rod starts to rotate, and separating a dial reading R1 pointed by a pointer when the sample from the blade is read; D, after the pointer is reset, pressing the start button again, so that the sample moves in the other direction, and separating a dial reading R2 pointed by the pointer when the sample from the blade is read; E, averaging the data measured in the step D andthe step E; F, measuring readings R of other samples; and G, calculating the softness S of each sample. The method provided by the invention can be used for accurately testing the softness of the softcoated abrasive tool.
Description
technical field [0001] The invention relates to a coated abrasive, in particular to a method for testing the softness of a soft coated abrasive. Background technique [0002] Soft coated abrasives generally need to test the softness of coated abrasives, especially all kinds of soft abrasive cloths produced by coating with textiles as the substrate. The so-called soft abrasive cloth is based on textiles. Coated abrasives made of adhesives and abrasives have a certain degree of softness, but the current test method for the softness of coated abrasives is not perfect, there are many testing steps, the testing process is quite complicated, and the softness test The results were not accurate enough either. [0003] Therefore, it is necessary to make further improvements. Contents of the invention [0004] The object of the present invention is to provide a simple, convenient, accurate and practical method for testing the softness of soft coated abrasives, so as to overcome th...
