Overview
The paint film abrasion instrument (model: JM-IV dual-use) is suitable for testing the paint film resistance performance and wood veneer wear resistance performance. The instrument complies with GB/T15036.2, GB/T18102, GB/T4893.8, ISO7784.2 and other standards, and can choose "paint film configuration", "wood configuration" or "dual-use configuration" according to the test requirements. Rotation speed of the turntable can be specially set according to user requirements within the range of 50-100r.P.m.
Features
1. The double abrasion wheel design is adopted. The abrasion wheel rotates with the turntable and generates relative movement and slippage. The sample surface is abraded at all angles to form a complete ring.
2. It is an advanced accelerated Abrasion testing instrument that can change the test function by replacing Accessories.
3. The repeability test can be carried out at the same point until the material is damaged or worn off (thickness of about 0.5 inches).
4. By selecting different abrasion wheels and Accessories, a variety of real abrasion situations can be simulated.
5. Use carefully selected high-mass abrasion wheel abrasive to ensure test Reliability.
6. The pressure applied by the abrasion wheel is precisely controlled in grams.
7. Stability of abrasion wheels is strictly quality controlled.
8. Electronic measurement of turntable rotation.
9. Equipped with a vacuum cleaner to remove wear debris.
Principle
The instrument consists of two abrasion abrasive wheels arranged on the turntable. When the turntable swirls/spins, the left abrasion abrasive wheels rub the surface of the template from the outside to the inside, and the right abrasion abrasive wheels rub from the inside to the outside. After the turntable swirls/spins for one week, the abrasion marks formed on the surface of the template consist of two rings that overlap and intersect in an X shape. This design makes the surface of the template subject to friction in all directions, overcoming the shortcomings of one-way reciprocating Wear resistance instruments.
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 the instrument should be covered.
• When not in use for a long time, the abrasive wheels should be removed and stored properly.
• The instrument needs to be overhauled and refueled every one to two years.
