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, such as deck paint, floor paint, road paint, etc.; it can also be used to test the wear resistance of paper, plastic, Spinning & weaving products, decorative panels, etc. The instrument adopts stepper motor drive, programmable control, and the working parameters and running 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 Rotation speed changes caused by grid voltage fluctuations and improve Rotation speed Stability
2. Programmable control, LCD display working parameters and operating status
3. Simple operation, reliable performance, flexible and convenient use
4. Rotation speed parameters of abrasive wheels can be modified according to user special requirements
5. Choose abrasive wheels of different materials to adapt to different testing needs
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 abrasion arrangement makes the sample surface subject to friction in all directions, avoiding obvious directional defects and making the abrasion evaluation more objective.
Applications
Coating wear performance test, wood wear performance test, paper wear performance test, plastic wear performance test, Spinning & weaving wear performance test, decorative board wear performance test
Standards
GB/T1768、GB/T17657
Steps
1. Select the appropriate 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 abrasion test
6. Observe the running status of the LCD display
7. Evaluate abrasion results after test completion
Notice
• Different specifications of turntable components and abrasive wheels are required for paint film wear performance testing and wood wear performance testing
• Rotation speed requirements for abrasive wheels should be explained in advance when ordering
• When ordering, you need to clearly select "paint film configuration", "wood configuration" or "dual-use configuration".
• Make sure that all parts of the instrument are installed correctly before use
• Pay attention to observe the running status of the instrument during the test
