Enforce the standard.
It meets the requirements of the test method in the standard YY T 0113-2015 "Test Method for Abrasion Performance of Dental Composite Resin".
Technical parameters. Control system: PLC;
Operation interface: color 7-inch touch screen, Chinese and English switching, at least 2 languages;
Abrasion times setting: can be set arbitrarily on the touch screen;
During the abrasion process, the specimen moves in a circular motion with a constant velocity and constant radius relative to the abrasive couple, and then moves in the vertical direction in an intermittent manner and moves in free fall. After the specimen is dropped, the abrasive is extruded under the abrasion load and the opposite part is in contact, and the friction of the relative circular motion mode is realized, and the friction cycle is 30 degrees. After each friction cycle is completed, the specimen is raised by 10mm 05mm, rotation 90°, and 30° of non-contact circular motion relative to the grinding piece. The circumferential radius of the specimen is 275mm, the linear velocity of the center of the specimen is 75mm s.;
During the abrasion process, whenever the specimen falls, the abrasive can be collected and padded between the specimen and the pair of wearers, with a thickness of not less than 5mm.
The abrasion load is 22N and 172N;

The dental composite resin abrasion performance tester is a device used to test the abrasion resistance of dental composite resin. Dental composite resin is a material widely used in the field of dental restoration and cosmetology, and its wear resistance is one of the important indicators to evaluate its quality and service life.
Dental composite resin abrasion performance testers typically use specific abrasion test methods to simulate the wear process of composite resins in the oral environment to evaluate their wear resistance. During the test, the specimen is placed in the abrasion device of the tester, and the abrasion resistance of the composite resin is evaluated by simulating the actions of chewing and brushing, and the mass loss or surface morphology change before and after wear is measured.
The test results of the dental composite resin abrasion performance tester can provide important reference information for dentists and materials researchers, and help to select the right dental composite resin material to improve the effectiveness and service life of dental restoration and cosmetic. At the same time, the equipment can also be used for the research and development and optimization of dental composite resin materials, and promote technological progress in the field of dental restoration and cosmetology.
