Rubber is characterized by both high elasticity and high viscosity. The elasticity of rubber is produced by changes in the conformation of its crimped molecule. The interaction of rubber molecules can impede the movement of molecular chains and show the characteristics of viscosity, so that the stress and strain are often in an unbalanced state.
The principle of rubber shock pad
The long curved molecular structure of rubber and the weak secondary forces between the molecules make the rubber materials exhibit unique viscoelastic energy, thus having good shock absorption, sound insulation and buffering properties. Rubber components are widely used to isolate vibration and absorb shock, because they have the characteristics of hysteresis, damping and large reversible deformation.
The hysteresis and internal friction characteristics of rubber are usually expressed by loss factor. The larger the loss factor, the more significant the damping of rubber, the more obvious the shock absorption effect.
Application of rubber shock pad
Rubber shock absorber products mainly include rubber shock absorber, rubber air spring, rubber fender, sponge and cork rubber shock absorber, elastic connecting shaft joint and flexible pipe, etc.
1. Rubber cushions are mostly rubber and metal composite products, with double-plate, cylindrical, sheet and other forms. It is used for damping and sound insulation of various machines, meters, axles and pipelines.
2. Rubber air spring. It is better than metal spring in shock absorption and impact resistance, and is mainly used for vehicles. Its structure is similar to that of the tire without inner tube, with the curtain layer as the pressure-resistant layer, the inner rubber layer and the outer protective rubber layer of oil and aging resistance.
3. Rubber support is made of rubber sheet and rigid material. The latter can improve the compressive strength of the support, while the impact of shear strength is very small. The rubber bridge bearing can transfer the bridge load to the pier and at the same time adapt to the bridge deformation and reduce vibration. Rubber building supports can reduce subway and surrounding vehicles as well as the impact of earthquakes on buildings.
4. Rubber non-slip mat. It is made of latex from rubber tree and is a polymer of isoprene. It has good wear resistance, high elasticity, breaking strength and elongation. It is prone to ageing in the air, becoming viscous when exposed to heat, expanding and dissolving easily in mineral oil or gasoline, alkali-resistant but not strong acid-resistant. Advantages: good elasticity, acid and alkali resistance.
Nowadays, domestic rubber non-slip mat can be said to be full of beautiful things in eyes, but how much does it really have anti-slip function? Rubber anti-skid mat is a combination of various functions, not only with the basic function of hydrophobic anti-skid, but also with the basic function of wear resistance and pressure resistance. The range that it suits is very wide also, besides general household can be used, industrial manufacturing also can use its achieve prevent slippery effect, let working environment have safe safeguard.
