Dental Composite Resin Wear Resistance Tester
YKT-MH01
YKT-MH01 Dental Composite Resin Wear Resistance Tester is designed in accordance with YY/T 0113-2015 "Dentistry - Test method for wear resistance of dental composite resin." The tester primarily performs preliminary wear and wear loss testing of specimens. After preliminary wear, the specimens are cleaned and dried, and their initial weight is measured using an analytical balance with an accuracy of 0.0001g. The specimens are then placed back to the fixture for wear testing. The wear process is performed automatically by the machine.
Product Features
After the specimen falls, the abrasive is squeezed into contact with the antagonist under the action of an wear load, achieving relative circular motion with a 30° friction cycle. After each friction cycle, the specimen is raised by (10±0.5) mm, rotated 90°, and then undergoes a 30°non-contact circular motion relative to the antagonist. The circular motion radius of specimen is 27.5 mm. During the wear process, the linear velocity at the specimen center is 75 mm/s.
During the wear process, each time the specimen falls, the abrasive is collected and placed between the specimen and the antagonist, with a thickness of at least 5 mm.
The abrasive is a mixture of fluorite concentrate (grade FC-98) with a grit size of 110-120 mesh and distilled water, conforming to YB/T5217-2005, and a water-to-powder mass ratio of 1:4.
