Rubber Seal Strip Basic Classification

Edit:Rizhao Tongrui Rubber Products Co.,Ltd  Date:Oct 09, 2017

Rubber seal can be based on cross-sectional shape, curing method, the use of parts and uses, the use of materials and other methods for classification.

Basic classification

Rubber seal can be based on cross-sectional shape, curing method, the use of parts and uses, the use of materials and other methods for classification.

According to vulcanization method

(1) non-continuous vulcanization method (the extruded strip according to a certain length of the cut, into the vulcanization tank curing, the extruded strip of semi-finished products into the model vulcanization);

(2) continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method and several other methods). A. Microwave continuous vulcanization composite seal: microwave curing technology is the 20th century, 70 years after the application of foreign energy crisis and widely promoted production technology. The use of microwave continuous vulcanization technology can not only produce a variety of materials, such as metal core, solid core and sponge rubber composite tape, and, in terms of energy saving, improve work efficiency and other advantages of other continuous vulcanization device. This technology is recognized by the world as the best method of producing extruded products. Microwave heating is characterized by heat generated directly in the heated object, rather than as usual from the external input, so not only heat fast, and uniform distribution, is conducive to improving product quality and greatly shorten the time spent heating. B. salt bath continuous vulcanization seal: salt bath with nitrite salt bath system, the larger environmental pollution, has been gradually eliminated.

Vulcanization (Tmax: 450 ° C and Vmax: 60 m / s) can also achieve the effect of flame pretreatment, and safety greatly improved.

Second, according to the rubber seal material classification

Car seal rubber material with dense plastic, sponge rubber and hard rubber three. Hard rubber hardness up to Shore A95. Seal of the rubber used more anti-aging, low temperature, water resistance, chemical resistance, especially ozone-resistant EPDM (EPDM). EPDM can be combined with steel strip, steel wire braid, TPE, flannel, flocking, PU coating, silicone coating, etc., to ensure that the car interior and outside and their own waterproof, dust, noise, heat insulation, vibration Grinding and decoration.

Under normal circumstances EPDM seal can be stable for more than ten years. You can also choose chloroprene rubber (CR) with good ozone resistance and good anti-aging properties.

Taking into account the process properties of commonly used compounds, and sometimes need to use and use rubber, such as natural rubber (NR) and CR and styrene butadiene rubber (SBR) three kinds of rubber and polyethylene (PE), EPDM and NR rubber and Improved resistance to ozone.

Use points

Car seal,

Doors and windows seals, ship seals, mechanical seals, and other three categories; mechanical seals, including the cabinet seal, container seals, and so on.

principle

By the seal and install the two parts. Such products mainly use the body structure of the lip, cavity, flange and other parts of the flexibility and assembly of coupling parts (glass, metal parts, etc.) surface contact pressure and sealing and decorative role. Generally in the range of -50 ~ 70 ℃. By the seal and install the two parts.
