1.Plate rubber bearing: except under special conditions (cold areas), it has basically replaced the commonly used bearings like linoleum cushion, curved steel plate, reinforced concrete pendulum and other forms. The allowable compressive stress of rectangular and circular bearings is 10MPa, which is suitable for Bridges with small spans. It is not suitable to use spherical crown rubber bearings or...
O-ring seals are suitable for installation in a variety of mechanical equipment, which seals in specified temperature, pressure, as well as different liquid and gas medium, in the static or movement state. A large number of various types of sealing components are applied in machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, c...
The working life of O-ring under dynamic pressure is 5-10 times higher than that of conventional rubber sealing products. Compared with other types of sealing rings, The O-ring has the following advantages: 1.Suitable for both dynamic and static sealing conditions; 2.Suitable for a variety of motion modes: rotary motion, axial reciprocating motion or combined motion (such as rotary reciprocating m...
Perfluorinated rubber has three characteristics: First, high temperature resistance; Second, strong corrosion resistance. It has a strong dielectric performance in the acid and alkali environment; And the third is super cleanliness. Those characteristics make it widely used in the following fields: first, chemical processes and petroleum refining. In this field, perfluorinated rubber seals a...
There are many kinds of rubber products, but the production process is basically the same. The basic technological process of rubber products with general solid rubber as raw material includes six basic processes: plasticizing, mixing, calendering, pressing, forming and vulcanizing. Of course, raw material preparation, finishing, inspection and packaging and other basic processes are also necessar...
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...
