Compression test of cff filter<\/a>.<\/p>\n

2.24 Compressive strength testing The testing instrument is CMT series computer-controlled electronic universal material testing machine.<\/p>\n

The sample size is a cylinder with a diameter of 20\u00b10.5mm and a height of 20\u00b11mm. Five samples per group. The test specimens are produced by the same process as the product production. The pressing surface of the sample is ground flat, and the two pressing surfaces are kept parallel to each other.<\/p>\n

(1) Measure the diameter of the upper and lower pressure surfaces of the sample, accurate to 0.01cm.<\/p>\n

(2) Place the sample in the center of the lower platen of the testing machine, and apply pressure evenly at a speed of 20 \u00b1 5 kg\/cm2 per second, until the pressure gauge pointer is reversed and the test is stopped immediately.<\/p>\n

22.5 Testing of Flexural Strength<\/p>\n

The testing instrument is CMT series microcomputer-controlled electronic universal material testing machine. Specimen specifications are 10\u00b11mm high, 20\u00b11mm wide and 120\u00b12mm long. 5 samples per group. Manufactured using the same process as the production of the finished product. The surface of the sample is ground flat.<\/p>\n

(1) Before the test, remove the impurity particles on the surface of the sample<\/p>\n

(2) Put the sample in an oven, dry it at 110\u00b15\u2103 for 2 hours, and then put it in a desiccator to cool it to room temperature.<\/p>\n

(3) Adjust the distance between the supports to 50mm, put the sample on the support, apply a load at a speed of 2\u00b10.5N\/S until the sample is damaged, and read the load number at the time of failure<\/p>\n

(4) Measure the thickness and width of the broken part of the sample, accurate to 0.01mm, and the calculation formula is as follows<\/p>\n
