The main function of rubber waterproof plate is to prevent the leakage of liquid and the volatilizing of gas. In rock engineering, waterproof plate is mainly used to prevent seepage and isolate , but it also plays the role of strengthening and protection at the same time. The general width of the waterproof plate 4-6m, weighting from 200 to 1500 grams per square meter. These characteristics ...
Bellows are tubular elastic sensing components connected with foldable wrinkles along the direction of folding and stretching. Bellows are widely used in instruments to convert pressure into displacement or force. It is mainly used as a measuring component of pressure measuring instrument to convert pressure into displacement or force. The bellows have thinner wall and higher sensitivity, and the ...
Because of its excellent thermal conductivity, insulation, shockproof and convenient assembly, silicone caps have been applied in various fields, such as: heating transistors, diodes, audions, switching power supply, uninterruptable power supply equipment, heat dissipation of power amplifiers, heat dissipation of automobile electronic equipment, cooling fins and heat dissipation fins, and other ap...
In the process of storage and use of rubber, affect by the environment and human forces, the performance and appearance of rubber changes with time, which is the phenomenon of aging. So what causes rubber to age? There are mainly 7 factors as followed: 1.Oxygen: free radical chain reaction will occur between oxygen and molecules of rubber when molecular chains fracture or over cross linked, which ...
Raw rubber is elastic and lacks the plasticity necessary for processing, so it is not easy to process. In order to improve its plasticity, it is necessary to plasticize the raw rubber, so that the coordination agent can be easily dispersed in the raw rubber in mixing process. Meanwhile, in the rolling and forming process, it is also helpful to improve the permeability of the rubber into the fabric...
The process of converting plastic rubber to elastic rubber is called vulcanization. It is to add a certain curing agent such as sulfur, curing accelerator and so on into the semi-finished products made of raw rubber. In the vulcanization tank in the specified temperature heating, heat preservation of the raw glue between the linear molecules linked to each other into a three-dimensional network st...
