Application of Universal Testing Machine: This types of tensile testing machines is designed for conducting tensile, compression, bending, shearing, bonding strength, peeling, tearing and other tests for shoes, rubber, plastic, leather, metal, nylon line, fabric, paper, aviation, packaging, construction, petrifaction, electrician, vehicle and other materials. It is a basic equipment of quality control, receiving inspection, physical test, mechanics research, material development.
Correct use of computerized universal testing machine: When the electronic stepless speed regulation adjusts the lifting speed, it cannot be operated too fast. Before using the 50KN power machine, pay attention to check the tightening of the clamp tightening screws. When lifting the lower clamp, the movement should be stable, avoid collision, and often check the tightness of the clamp screw. When replacing the test fixture, pay attention to cooperate to prevent bruises.
Testing to ASTM D4060 involves mounting a flat specimen to a turntable that rotates horizontally at a fixed speed. Two arms, each supporting an abrading wheel, are then lowered so that each wheel touches the surface. Before starting the test, a “suction arm” is lowered between the wheels to remove the abraded material from the sample’s surface. The turntable then starts rotating forcing rub-wear action of the wheels against the sample’s surface for the specified number of cycles or until a given mass of coating has been lost or until the wheels start exposing the substrate.
Reagent Preparation: Prepare corresponding reagents according to different test standards and keep them as standby. If sodium perborate is required in the test, the preheating temperature shall not exceed 60℃ when preparing the solution, and it shall be used within 30 minutes at most to prevent the loss of oxidant. Solution Warm-up: Put the specified volume of solution and a specified number of steel balls into the stainless steel cup, put the stainless steel cup into the launderometer for a few minutes, preheat to the specified temperature. Then put in the prepared sample for test. Discover more information on https://www.gesterinstruments.com/.
