Whether it is a car, a bicycle, an electric car, etc., there will be wheels, and there are inner tubes on the wheels. This kind of inner tube material requires special testing instruments for testing, and the rubber inner tube tensile testing machine is one of them.

Rubber inner tube tensile testing machine JM-101PT detection range: 0.05KN~10KN, 5KG~1000KG

Among the rubber inner tube materials, the butyl rubber inner tube has a wide range of uses, with good air tightness, heat resistance, elasticity, aging resistance and small deformation. After the inner tube is loaded, the air pressure is above 8MPA, and the air tightness is high. The carcass reduces the natural leakage of gas, and is less inflated than the natural rubber inner tube in use, and it is also more fuel-efficient in driving.

The high temperature resistance of the butyl rubber inner tube is superior to that of the natural rubber inner tube. When the car is running at a high speed for a long time, the temperature of the tire cavity is very high, which makes the inner tube rubber self-vulcanize quickly and affects the service life. The butyl rubber inner tube is more resistant to aging and use time Longer.

Rubber tensile test steps:

1. Install the rubber sample on the clamp first, and set the tensile speed to 500mm/min.

2. Click to start the test, and use the ruler to track the working marking line of the sample when doing the tensile test.

3. According to the test requirements, record the load when stretched to the specified elongation, the large load when the rubber is broken and the elongation at break, the time required for breaking, and record the elongation curve.

4. Measure the permanent deformation value after the test piece is broken, with an accuracy of 0.5mm.

5. The test results can be saved in the computer or printed out using a printer.

6. After the test, remove the sample from the clamp and turn off the main power supply of the tensile testing machine.
