This kind of hose is used for a long time in the occasion of contact with chemicals. Chemicals are mainly a variety of acids, alkalis, salt solutions, due to their oxidation of rubber products, often caused by the decomposition of rubber and compatibility with the agent, resulting in corrosion of the vulcanised rubber or caused by the swelling of the rubber.
Acid, alkali requirements of the hose is not high, you can use natural rubber or with nitrile rubber, chloroprene rubber and use; for contact with more corrosive media hose, you can choose butyl rubber, chlorosulphonated polyethylene rubber, fluoroelastomer and other special rubbers. The vulcanisation system used in the spirit of increasing cross-linking density, improve the modulus of elasticity of the vulcanised rubber, is to improve the vulcanised rubber chemical corrosion resistant media important measures. Chemical corrosive medium resistant rubber formula selected filler should be chemically inert, not easy to react with chemical corrosive media, not be eroded, does not contain water-soluble electrolytes and other principles. Carbon black is generally more stable to chemical corrosive media, filler carbon black also increases the crosslinking density of the rubber, improve the modulus of elasticity of vulcanised rubber, to improve the corrosion resistance of the rubber is beneficial. According to the requirements of the mechanical properties of the rubber material to select the variety of carbon black and filling amount (such as hardness requirements to determine the carbon black filling fraction). Hose formulations are generally used in high wear-resistant carbon black or semi-reinforced carbon black, or both with better results. Other fillers can be selected barium sulphate, clay, etc..
