standard classification
Rubber securing strips can be identified according to a number of approaches such as cross-sectional form, vulcanization approach, location as well as purpose of use, and products utilized.
According to vulcanization technique
( 1) Discontinuous vulcanization approach (reduce the extruded rubber strip according to a specific length, placed it into the vulcanization tank for vulcanization, as well as make the extruded rubber strip semi-finished item
put into the version to vulcanize);.
( 2) Continuous vulcanization technique (microwave continuous vulcanization technique, salt bathroom continuous vulcanization approach, hot air continual vulcanization technique.
chemical method, and so on). A. Microwave continual vulcanization of composite sealing strips: Microwave vulcanization modern technology is just one of the essential elements of the foreign power dilemma in the 1970s.
It is a manufacturing innovation that has actually been applied and also widely promoted. Utilizing microwave continual vulcanization technology can not only create metal core, strong core rubber and sponge.
Glue a selection of material composite rubber strips, and also it transcends to various other continual vulcanization devices in regards to energy saving as well as work efficiency. This innovation is.
It is recognized worldwide as the very best procedure for creating extruded items. The quality of microwave home heating is that warm is produced directly in the warmed things rather than.
It is input from the outside as usual, to make sure that not only the warm is created rapidly, however likewise the circulation is uniform, which contributes to enhancing product high quality and also greatly shortening the home heating time.
time invested. B. Continuous vulcanization of securing strips in salt bathroom: Salt bathroom vulcanization embraces a salt bath system having nitrite, which has a huge environmental pollution and has actually been progressively.
progressively gotten rid of.
Vulcanization (Tmax: 450 ° C as well as Vmax: 60m/s) can additionally accomplish the result of fire pretreatment, as well as the safety and security is considerably enhanced.
Second, according to the rubber securing strip product category.
There are three type of rubber products for auto securing strips: portable rubber, sponge rubber and also difficult rubber.
The hardness of hard rubber can reach Shore A95. The rubber of the sealing strip is mainly used for aging resistance, reduced temperature resistance, water vapor resistance, chemical rust resistance, particularly.
It is ethylene propylene diene monomer (EPDM) immune to ozone aging. EPDM can be integrated with steel belt, steel cord braided belt, TPE, fleece, gathering, PU covering,.
Silicone coating as well as various other substances can ensure the water-proof, dustproof, audio insulation, warm insulation, resonance reduction, anti-wear and ornamental features of the auto inside as well as the outdoors as well as itself.
In general, EPDM sealing strips can be made use of stably for greater than ten years. Neoprene (CR) with good ozone resistance and also excellent waterproof rubber seal strip aging resistance can likewise be selected.
Thinking about the process performance of commonly utilized rubber materials, sometimes it is necessary to select and also use rubber, such as all-natural rubber (NR) and also Styrene-butadiene and cr rubber (SBR).
Rubber or polyethylene (PE), EPDM as well as NR rubber as well as plastic are made use of to improve ozone resistance.
Part of use.
cars and truck seal,.
Door and window securing strips, ship securing strips, mechanical securing strips as well as various other 3 categories; mechanical securing strips include cabinet sealing strips, container securing strips, and so on principle.
It contains two components: sealing and also installation. This type of item mainly makes use of the flexibility of the lips, cavities, flanges as well as other parts in the body framework and also the assembly.
The contact stress produced externally of the combining (glass, steel, etc) serves as a seal and also design. Generally used in the variety of -50 ~ 70 ℃.
It includes 2 parts: sealing and installation.
This type of product mostly utilizes the elasticity of the lips, cavities, flanges and also various other components in the body framework and the get in touch with stress created externally of the put together coupling parts (glass, steel components, etc) to play the duty of sealing and design.
Usually utilized in the variety of -50 ~ 70 ℃.
