The curled long chain molecular structure of rubber and the weak secondary force between the molecules make the rubber material present unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties. Rubber components are widely used to isolate vibration and absorb shock because of their hysteresis, damping and reversible large deformation characteristics.
The hysteresis and internal friction characteristics of rubber are usually expressed by loss factor. The greater the loss factor is, the more significant the damping and heating of rubber are, and the more obvious the shock absorption effect is.
Rubber shock absorber products mainly include rubber shock absorber pad, rubber air spring, rubber fender , sponge and cork rubber shock absorber pad, elastic coupling and flexible nozzle, etc.
1. Rubber cushion. Most of them are rubber and metal composite products, including double-plate, cylindrical, sheet and other forms, which are used for shock absorption and sound insulation of various machinery, instruments, axles and pipelines.
2. Rubber air spring. It has better shock absorption and shock resistance than metal springs and is mainly used in vehicles. The structure of the tire is similar to that of tubeless tire. The cord layer is used as a pressure layer, with an air-tight rubber layer inside and an oil-resistant and aging-resistant protective rubber layer outside.
3. Rubber bearings. It is made of rubber sheet and rigid material (steel plate, wire mesh, canvas). The latter can improve the compressive strength of the bearing, but has little effect on the shear strength. Rubber bridge supports can transfer bridge loads to piers and abutments, and can adapt to bridge deformation and reduce vibration. Rubber building bearings can reduce the impact of subway and surrounding vehicles and earthquakes on buildings.
4. Rubber anti-skid pad. It is made of latex collected from rubber tree and is a polymer of isoprene. It has good wear resistance, high elasticity, breaking strength and elongation. It is easy to aging in air, viscous in heat, easy to expand and dissolve in mineral oil or gasoline, alkali-resistant but not strong acid-resistant. Advantages: good elasticity, acid-alkali resistance.
Nowadays, many rubber anti-skid pads in our country can be said to be dazzling and dazzling. But how many anti-skid pads really have anti-skid function? Rubber anti-skid pad is a combination of many functions. It not only has the basic function of hydrophobic and anti-skid, but also has the basic super-strong wear resistance and pressure resistance. The suitable range is very wide. In addition to ordinary household use, industrial manufacturing can also use it to achieve anti-skid effect, so that the working environment is more secure and necessary to prevent. One of the cushion products.
