Rubber seal strips can be classified according to several methods such as section shape, vulcanization method, use place and purpose, use material, etc.

One, according to the vulcanization method

1: non-continuous vulcanization method (after cutting the extruded rubber strip according to a certain length, put it into the vulcanization tank for vulcanization, and put the extruded semi-finished rubber strip into the model for vulcanization);

2: continuous vulcanization method (microwave continuous vulcanization method, salt bath continuous vulcanization method, hot air continuous vulcanization method). A. Microwave continuous vulcanization compound seal strips: microwave vulcanization skills were used and widely promoted in the 1970s after the foreign energy crisis. The choice of microwave continuous vulcanization technology not only can produce by metal core, solid core rubber and sponge rubber a variety of materials composite rubber strip, and, in energy saving, progress in efficiency and other aspects than other continuous vulcanization method equipment superior. This skill is internationally recognized as a good technique for producing extruded products. The characteristic of microwave heating is that the heat is generated directly in the heated object, rather than from the external input as usual, which not only generates heat quickly, but also distributes evenly, which is conducive to the improvement of product quality and greatly reduces the heating time. B. Salt-bath vulcanization seal strip: salt-bath vulcanization USES salt-bath system containing nitrite, which causes great pollution to the environment and has been gradually eliminated.

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

Two, according to the rubber seal material classification

The rubber material of car sealing strip has compacted glue, sponge glue and hard rubber 3 kinds.

Hardness of hard rubber up to shaw A95. The rubber material of seal strip is used to resist aging, low temperature, water and gas, chemical corrosion, especially the ethylene propylene diene diene rubber (EPDM) which is resistant to ozone aging. EPDM can be combined with steel belt, steel wire braid belt, TPE, flintcloth, flocking, PU coating, organosilicate coating, etc., to ensure the waterproof, dustproof, sound insulation, heat insulation, vibration, anti-wear and decoration effect of the car and the outside. Generally, EPDM seal strip can be safely used for more than ten years. Also can choose has the outstanding ozone resistance function and the outstanding aging resistance function neoprene rubber (CR).

Considering the process function of commonly used rubber, sometimes also need to choose and use rubber, such as natural rubber (NR) and CR and SBR rubber (SBR) three kinds of rubber with or polyethylene (PE), EPDM and NR rubber with type to improve ozone resistance.

Iii. Use part classification

Rubber seal strip, car seal strip, door and window seal strip, ship seal strip, mechanical seal strip, etc. The mechanical seal strip includes cabinet seal strip, container seal strip, etc.

The principle of

It consists of two parts: the seal and the device. This kind of product primarily USES the flexibility of the lip, cavity, flange and other parts in the body structure and the contact pressure of the coincidence parts (glass, metal parts, etc.) appearance to seal and decorate the effect. Generally used in the range of -50 ~ 70℃.
