Overview
JM-V type paint film Wear meter is manufactured with reference to GB/T1768-2006 paint film wear resistance performance test parameters, and takes into account the test parameters of GB/T17657 on wood wear resistance performance, providing a multi-purpose wear resistance performance test means. It is suitable for laboratory testing the wear resistance performance of various coatings, and can also be used for paper, plastic, Spinning & weaving products, decorative boards, etc. The instrument is driven by a stepper motor, programmable control, and the working parameters and 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. Made with reference to GB/T1768-2006 and other standards, taking into account the wood wear resistance test parameters, it is widely used.
2. Stepper motor drive is used to avoid the influence of grid voltage fluctuations, Rotation speed is stable, and the test results are more comparable.
3. Programmable control, users can modify parameters such as abrasive wheels Rotation speed according to special requirements.
4. The LCD screen displays the working parameters and status, and the operation is simple and intuitive.
5. Abrasive wheels of different materials can be used according to different test sample requirements.
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 swirls/spins, 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, thereby forming a series of mesh-like intersecting circular friction marks on the sample surface. This arrangement causes friction in all directions of the sample surface, avoiding the directional defect of reciprocating Wear meters in a single direction, and making the abrasion evaluation more objective.
Applications
The laboratory tests the wear resistance performance of various coatings (such as deck paint, floor paint, road paint, etc.), paper, plastic, Spinning & weaving products, decorative panels, etc
Standards
GB/T1768-2006、GB/T15036.2、GB/T15102、GB/T18102、GB/T4893.8、ISO7784.2
Steps
1. Install the specimen on the horizontal turntable.
2. Select the appropriate abrasive wheels according to the test requirements and install them.
3. Select and load the corresponding load weight according to the test standard (such as paint film or wood).
4. Rotation speed and other parameters of abrasive wheels are set through the programmable controller.
5. Start the instrument and monitor the working status and parameters through the LCD screen.
6. After the test is completed, remove the sample for abrasion evaluation.
Notice
* If the user has special requirements for abrasive wheels Rotation speed when ordering, it can be satisfied by modifying the programming parameters.
* For different test samples, abrasive wheels of the corresponding material should be selected.
Before operation, please ensure that the instrument is placed smoothly and familiar with relevant safety operating procedures.
Check abrasive wheels abrasion regularly and replace or equilibrate if necessary.
* The instrument does not contain abrasive wheels and needs to be configured separately according to test requirements.
