Overview
RONGJIDA JM-IV paint film abrasion instrument is suitable for testing the wear resistance performance of paint film and wood veneer, and complies with GB/T15036.2, GB/T4893.8 and ISO7784.2 standards. Users can choose "paint film configuration", "wood configuration" or "dual-use configuration" according to the test requirements, and the turntable Rotation speed can be customized on demand within the range of 50-100r.P.m.
Features
1. Adopt double abrasion wheel design, the abrasion wheel rotates with the turntable and generates relative sliding motion, forming full-angle abrasion, and the simulation effect is more comprehensive.
2. Excellent abrasion process, can be carried out at the same point, repeability test, until the material is damaged.
3. By replacing different abrasion wheels and Accessories, a variety of real abrasion scenarios can be simulated with various functions.
4. The key parameters are strictly controlled, the abrasion wheel has a high abrasive mass, and the pressure is precisely applied in grams.
5. Equipped with an electronic counter to measure the number of revolutions, and a built-in vacuum cleaner to remove wear debris to ensure a clean test environment.
Principle
The instrument works together on the turntable through two abrasion abrasive wheels. When the turntable swirl/spin, the left abrasive wheels are rubbed from the outside to the inside, and the right abrasive wheels are rubbed from the inside to the outside. After one week of swirl/spin, two ring abrasion marks that overlap each other and intersect in an X shape are formed on the surface of the sample, ensuring that the surface of the sample is rubbed in all directions, overcoming the limitations of one-way abrasion.
Applications
Lacquer film performance test, wood veneer wear performance test
Standards
GB/T15036.2、GB/T15102、GB/T18102、GB/T4893.8、ISO7784.2
Steps
The information does not provide specific operation steps.
Notice
• After the test, the power should be cut off, the instrument should be cleaned and covered.
• When not in use for a long time, the abrasive wheels should be removed and stored properly.
• It is recommended to overhaul and refuel once every one to two years.
