Overview
JM-VI abrasion instrument is manufactured with reference to GB/T1768 paint 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, and can also be used to test the wear resistance performance of paper, plastic, Spinning & weaving products, decorative boards, etc. The instrument adopts stepper motor drive, programmable control, and the working parameters and running status of the instrument are displayed by the LCD screen. The operation is simple, the performance is reliable, and the use is flexible and convenient.
Features
1. Manufactured according to GB/T1768 and GB/T17657 standard parameters, providing multi-purpose wear resistance performance test
2. Use stepper motor drive to avoid changes in Rotation speed caused by grid voltage fluctuations
3. Programmable control, LCD display working parameters and operating status
4. Rotation speed of abrasive wheels can be adjusted by modifying the programming parameters according to the special requirements of users
5. Different materials abrasive wheels can be used to adapt to different test sample requirements
6. Provide choice of paint film configuration, wood configuration or dual-use configuration
Principle
The abrasion instrument contacts two abrasion abrasive wheels at a predetermined distance 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 causes friction in all directions of the sample surface, avoiding obvious directional defects and making the abrasion evaluation more objective.
Applications
Coating wear performance test, deck paint, floor paint, road paint, paper wear performance test, plastic wear performance test, Spinning & weaving wear performance test, decorative plate wear performance test
Standards
GB/T1768、GB/T17657
Steps
1. Select the corresponding turntable assembly and abrasive wheels configuration according to the test requirements
2. Install the specimen sample on the horizontal turntable
3. Adjust the contact distance between abrasion abrasive wheels and the test piece
4. Set working parameters through Touchscreen
5. Start the instrument for testing
6. Observe the running status of the LCD display
7. Evaluate abrasion results after test completion
Notice
• For the test of paint film wear performance and wood wear performance, different specifications of turntable components and abrasive wheels are required
• Users need to specify the configuration requirements when ordering (paint film configuration, wood configuration or dual-use configuration)
• Rotation speed of abrasive wheels Special requirements can be made at the time of order, which can be met by modifying the programming parameters
• Select abrasive wheels of suitable materials according to different test sample requirements
• Pay attention to the difference between the actual weight of the load weight and the marked weight
