Experimental operation of Taber Abrasion Tester  Taber Abrasion Tester is also called Taber Abrasion Tester. Currently, this instrument is mainly used to test the abrasion resistance of leather and plastic, fabric, floor tiles, plywood and other mat... 1. This step can be cut the standard test piece, and then to be attached to the back of the test piece with double-sided tape (the other side should also be attached to Oh), double-sided tape to remove the paper, weigh the test piece and record the weight, bear paw record to four decimal places. 2. Before opening the test need to confirm the power supply voltage of AC220V, frequency of 50HZ. 3. Before the test lift the test arm of the equipment, and then start the power supply to try to run, we can check from here whether the machine is running properly, and then lift the test arm and vacuum arm, remove the test piece fixing nut and spacer (ring), and then use a wrench to loosen the fixing screw of the fixing ring and pick up the fix...

What are the tests that must be done on the interior parts of the car?   1、Flame retardant performance   Combustion safety performance is an important indicator of automotive interior materials. Automotive interior materials, especially textiles, must have good flame retardancy and fire retardancy. So that once the car fire danger can ensure that passengers have enough time to leave, or reduce the risk of fire.   Ordinary automotive textile materials may be used to a variety of fibers, because their composition and chemical structure are different, so their thermal and combustion properties are not the same. The current standard used for flame retardant performance testing is GB 8410-2006 "Combustion Characteristics of Automotive Interior Materials", which is applicable to all automotive interior materials. Common evaluation methods are: vertical combustion test, horizontal combustion test, 45° angle combustion test. 2、Atomization performance   Before the use of auto...

3 methods commonly used to test the wear resistance of automotive interior materials 1.Taber Abrasion Method-  Taber Abrasion Tester The American standard ASTM D3884 "Standard test method for abrasion resistance of textile fabrics (TABER apparatus)" provides for the Taber abrasion method, the test principle of the TABER abrasion method is: the test specimen is placed on a rotating platform, through The test principle of the TABER abrasion method is as follows: The specimen is placed on a rotating platform, and the specimen is worn by two rolling friction wheels on top of it under a certain load, with one friction wheel facing outward and the other friction wheel facing inward, forming a circular wear mark. After a specified number of rubbing cycles, the degree of wear of the specimen is evaluated by appearance. Test method: fix the specimen face up on the rotating platform and mount the selected grinding wheel on the supporting lever, after selecting the suitable load, lower ...

 from the yarn category: the wear resistance of yarn is closely related to the structure of yarn. Different spinning methods, different ways of winding fibers in the yarn, and different sizes of holding force between fibers also have different wear resistance. Traditional ring spinning yarn has poor wear resistance because most of the fibers are in the form of spiral threads, and when repeatedly rubbed, the spiral thread fibers gradually become axial fibers, and the yarn is easy to lose twist and disintegrate and wear off quickly. Non-traditional spinning yarn has obvious advantages in abrasion resistance, rotor yarn, jet yarn and vortex yarn are composed of two parts: yarn core and outer fiber, the surface of the yarn wrapped with irregular twisted fiber, the yarn is not easy to disintegrate, while the surface friction coefficient of the yarn is large, in the fabric between the yarn and yarn hold well, not easy to produce relative slip, so the abrasion resistance improved. Compare...

Detection principle.   When testing, the cylinder specimen is set on the rotating cylinder, and the nail hammer suspended by a chain is placed on the surface of the specimen. When the cylinder rotates at a constant speed, the nail hammer will randomly flip and jump on the surface of the specimen and hook the specimen to produce a hook on the surface of the specimen. After a specified number of revolutions, the specimen is rated against the standard sample for the degree of hooking. Two stations and four stations are available. Caution.   1, the average value of the experiment, if not a whole number, revised to zui nearest half level.   2、 The difference between the rating results of each piece of specimen should not exceed half a grade, otherwise the level of each specimen is reported separately.   3、 If the new cork liner is installed in the rolling box, it should be put into the empty tube for 200 hours before use.   4, the cork liner can be wiped with a small...

Qinsun Martindale Abrasion Tester Technical Advantage Analysis martindale abrasion tester working principle : Martindale Abrasion Tester refers to the test of textile products based on the standard system of Martindale method and its relationship, and through this test to test the abrasion resistance of the fabric, and abrasion resistance is an important index of textile product quality, which directly affects the durability of the product and the use of the effect, abrasion resistance refers to the fabric or with other substances in the process of repeated friction, resistance to Abrasion resistance refers to the resistance of the fabric to wear and tear during repeated friction with other materials. martindale abrasion tester diagram: There are various methods to test the abrasion resistance of textile products, such as flat grinding method, curved grinding method, folded edge grinding method and compound grinding method.
