Overview
JM-V type film Wear meter is manufactured with reference to GB/T1768-2006 film wear resistance performance test parameters, and at the same time takes into account the test parameters of GB/T17657 on wood wear resistance performance, providing a multi-purpose wear resistance performance test method. It is suitable for laboratory testing the wear resistance performance of various coatings, such as nail paint, floor paint, road paint, etc.; it can also be used for paper, plastic, Spinning & weaving products, decorative panels, etc. The instrument adopts stepper motor drive, programmable control, and the working parameters and progress status of the instrument are displayed on the LCD screen. The operation is simple, the performance is reliable, and the use is flexible and convenient.
Features
1. Adopt stepper motor drive to avoid speed changes caused by grid voltage fluctuations and improve working speed stability
2. Programmable control, LCD display working parameters and status
3. Simple operation, reliable performance, flexible and convenient use
4. The speed programming parameters of abrasive wheels can be modified according to the special requirements of users
5. Abrasive wheels of different materials can be used for different test samples
Principle
The wear meter brings two abrasion abrasive wheels at a predetermined distance into contact with the specimen template mounted on the horizontal turntable, and makes the central axis of the two abrasive wheels not in the same plane as the central axis of the turntable. When the turntable swirl/spin, the left abrasive wheels generate friction from the outside to the center of the sample surface, and the right abrasive wheels generate friction from the center of the sample surface to the outside, forming a series of mesh-shaped intersecting circular friction marks on the sample surface. This arrangement makes the sample surface subject to friction in all directions, avoiding the directional defect of one-way wear meter friction, and making the abrasion evaluation more objective.
Applications
Coating wear performance test, paper wear performance test, plastic wear performance test, Spinning & weaving wear performance test, decorative plate wear performance test
