PV3952 Hundred Grid Cross Scratch Tester

One,Scope of application of Baige Ten Finger Scratch Resistance Tester

PV3952Hundred grid cross scratch testerThis instrument is suitable for testing the scratch resistance of various automotive interior materials, such as plastics, rubber, leather, fabrics, coated materials, uncoated materials, and other composite materials. Scratch resistance tester is suitable for testing the scratch performance of various automotive interior materials, integrating three domestic testing standards(Five finger scraping method, hundred grid method, plastic finger scraping method). Hundred grid tenpointScratch tester This testing method is used to test the ability of surface materials to resist damage caused by scratching fingers. According to the nails or other hard objects that may come into contact with the material during use, different materials of scraping fingers are used to apply a certain pressure to the surface of the sample in the specified direction, stroke, and speed. The scraping head and the sample move relative to each other, producing a unidirectional, non reciprocating straight scraping trajectory, with parallel scratches between them.zuiThe final evaluation of the scratch sensory level of the material, the color difference between the scratched and non scratched areas, or the damage to the sample surfacezuiSmall scratching force

Three,Instrument features:

　　1. The instrument consists of a motor driven mechanism, a scraping component, a sample clamping and fixing device, etc.

　　2. The scraping component includes a scraping bracket, a scraping finger, a scraping finger positioning sleeve, and a pressure device(Weights and weight support rods)Wait.

　　3. The instrument can be freely installed, replaced, and disassembled with different specifications of scraping fingers, and can perform uniform unidirectional linear scraping motion under different loads.

　　4. The use of embedded systems and human-machine interface operation for automated control of the testing process, coupled with precision servo motors and ball screw transmission, plays a decisive role in controlling the scraping speed under relevant standards.

　　5. Using tungsten carbide material for scraping fingers to increase the service life of the instrument.

　　6. Made of aluminum alloy and stainless steel materials, the appearance is simple, lightweight, and corrosion-resistant.
