I. Industrial Rubber Waste Gas
II. Main Components of Industrial Rubber Waste Gas
Sources of VOCs
Organic waste gases produced in the process of rubber refining;
Organic waste gases in the process of dipping and drying of fibre fabrics;
Organic waste gas produced during calendering process;
Organic waste gas produced in vulcanization process;
Organic waste gases produced by resins, solvents and other volatile organic compounds when they are proportioned and stored.
There are three main sources of rubber exhaust gas:
1) Release of residual organic monomers. Raw rubber, such as natural, butyl benzene, cis-butyl, butyl, ethylene propylene, chloroprene rubber, etc., has great toxicity. Under the conditions of high temperature thermal oxidation, high temperature plasticization and combustion, these raw rubber dissociates trace monomers and harmful decomposition products, mainly alkanes and olefin derivatives.
2) Volatilization of organic solvents. Gasoline is widely used as organic diluent in rubber industry.
3) Thermal reaction products. When rubber products are produced at high temperature, it is easy to cause thermal reactions between various chemicals and form new compounds.
