Manufacturer of denture resin material wear and tear testing machine, dental restoration, artificial tooth wear resistance testerIt is a specialized equipment used to evaluate the wear resistance of composite resin materials in the oral environment, mainly simulating the friction and pressure during tooth chewing, and measuring the wear amount, surface morphology and other parameters of the material through standardized testing methods. ‌

Manufacturer of denture resin material wear and tear testing machine, dental restoration, artificial tooth wear resistance testerMain functions

This device can simulate chewing friction in the oral environment and evaluate the wear resistance of composite resin materials by controlling parameters such as friction cycle, pressure, and temperature. The test results can be applied to fields such as dental material research and development, product quality control, and oral restoration treatment.‌

The structural construction mainly consists of the following parts:

1. Test chamber: Simulate the human oral environment and control the pressure and other conditions required for wear testing. 2. Grinding wheel device: a device used for abrasion testing of composite resin materials, which can adjust the position and pressure of the grinding wheel.

2. 3. Control system: used to control the entire process of wear testing, including setting wear conditions and collecting data.

3. 4. Measurement system: used to measure parameters such as wear, surface morphology, and hardness of composite resin materials.

   
   

Technical parameter 1: Wear frequency setting: can be input according to user needs; 2. After the sample falls, under the action of wear load, the abrasive is squeezed and comes into contact with the opposite pair, and friction is achieved in a relative circular motion mode, with a friction period of 30 ° angle; After each friction cycle is completed, the sample rises by (10 ± 0.5) mm, rotates by 90 °, and completes a non-contact circular motion of 30 ° relative to the grinding pair. The circular motion radius of the sample is 27.5mm; during friction, the linear velocity at the center of the sample is 75mm/s. 3. During the wear process, whenever the sample falls, the abrasive can be collected and laid between the sample and the grinding pair, with a thickness of not less than 5mm; 4. The grinding pair is a specially made rubber plate with a diameter of (100 ± 1) mm and a thickness of 6 ± 0.2 mm. Shore hardness: 75 ± 5 °; 5. The abrasive is made by mixing fluorite concentrate with distilled water in accordance with YB/T5217-2005, grade FC-98, particle size 110 mesh to 120 mesh, with a water to powder mass ratio of 1:4; 6. A hair dryer with a power of approximately 50W; 7. High precision electronic balance: division value of 0.0001g; 8. Ultrasonic wave cleaning machine with a power of 400W; 9. The sample mold is made of stainless steel material
