Industry knowledge of external thread type shock-absorbing briquette

Rubber pads are divided into two types according to their structures. One is made by bonding, pressing, and vulcanizing multilayer rubber sheets. The other is made by bonding, pressing, and vulcanizing multiple layers of rubber sheets and stiffening steel plates (rubber bearings). It has satisfactory vertical rigidity for bearing straight loads, and can reliably transmit the reaction force of the superstructure to the pier. Outstanding elasticity to adapt to the rolling of the beam end; and large shear deformation to satisfy the horizontal displacement of the superstructure. This product has been widely used in bridge construction, hydropower engineering, and house anti-seismic facilities. Compared with the original steel support, it has the advantages of simple structure, convenient installation, saving steel, low price, simple maintenance, easy replacement, etc. The product has a low building height, which is beneficial to engineering design and cost reduction; it has an outstanding seismic isolation effect, which can reduce the impact of loads and seismic forces on the building. Plastic coated anti-rush screw

Improve the force between rubber molecules, that is, increase the viscous component in the rubber viscoelastic system, and then affect the movability of Oita's chain branches. When the rubber oscillates and deforms, 80% of it cannot adapt to external force changes, resulting in hysteresis and loss of results. The elastic energy of a part of deformation.

The natural damping effect of rubber is the result of applying rubber hysteresis loss, using it to absorb oscillating mechanical energy, convert it into heat energy, accumulate in the rubber, and gradually emit it. Therefore, rubber molecules should have greater intermolecular forces, compactness, and superior heat resistance and thermal conductivity.

Under normal temperature conditions, the loss coefficient values of natural rubber and butadiene rubber are small, while the loss coefficient values of styrene butadiene, neoprene, ethylene-propylene, polyurethane and silicone rubber are medium, and the loss coefficient values of butyl rubber are relatively large. Generally, the rubber with a larger loss coefficient should be selected for the vibration damping rubber material, so it is appropriate to choose these two types of rubber.
