What is Adhesive Tape?Adhesive tape is composed of two parts, a substrate and an adhesive, which connect two or more disconnected objects together. Its surface is coated with a layer of adhesive. In this article, let's learn about the method of tearing test for tape and the maintenance of testing machine. Details are as follows:
1.The test methods are mainly manifested in the following points:
1) When doing tape tear measurement, the thickness of the tear area of the measured sample shall not be less than 3 points, and the median shall be taken, and the thickness value shall not deviate from 2% of the median;
2) For comparison of multiple groups of samples, the median thickness of each group of samples must be 7 of the median of each group of samplesWithin the range of 5%, when the right-angle or crescent specimen test is carried out, the specimen is clamped into the upper and lower grippers to a certain depth along the axial alignment and tensile direction to ensure that it is fully and uniformly tightened in parallel positions
3) The trouser specimen is clamped into the gripper to a certain depth according to the regulations, and the specimen is placed on the gripper of the machine, and the tensile test is carried out at the specified speed until the specimen is broken
4) The right-angled and crescent-shaped specimens record their large values, and the trouser specimens record all the force values in the test process with an automatic drawing device
2.In order to ensure the normal operation of the equipment, its maintenance methods need to be done
1) Pay attention to the level of environment and location, whether the power supply voltage is rusty, etc.
2) Whether the buttons on the operation panel can work normally, whether the data is messed up, etc.
3) Whether the speed of the beam can operate normally, whether there is no trace of fracture on the motor belt, and whether the tightness is appropriate.
4) The attachment is replaced with different test contents, and the machine part is regularly lubricated with lubricating oil.
PullTesting machinesThe garbage after the test is taken away at any time, and wiped every day to keep it tidy.
