Q:How can the frictional properties of rubber improve?

Because of its high elasticity and low modulus, the friction and wear properties of rubber are greatly affected by their physical and mechanical properties. The hardness of rubber is smaller, contacting with a rigid object, the real contact area is large, and the real size of the contact area is an important factor, so the friction rubber hardness, have more effect on the friction performance.

Q:Why is natural rubber a strategic material?

Rubber is an important strategic material, in the national defence application is very extensive, for example, a tank with more than 800 kg of general rubber; thirty thousand ton warship with sixty-eight tons of rubber, military equipment, air force facilities, almost all defense engineering rubber footprint. The use of rubber made ship, tent, warehouse and protective equipment, clothing etc. there are many varieties of bath water. As for the anti - tip technology needs high temperature, low temperature, oil resistance, high vacuum resistance and other special properties of the rubber, the constitution of 0 products is indispensable. With the development of national defense modernization, rubber, which is capable of resisting the temperature range of minus 100-400 DEG C and capable of resisting various acids, bases and oxidants with special properties, is being developed and manufactured.
