The blue smoke emitted by silicone rubber products during vulcanization has a unique and unbearable odor, with complex components. Its composition and quantity largely depend on the formula and specific conditions during vulcanization. The volatile substances released from rubber during vulcanization mainly include the following:

1. Remaining monomers in polymers: generally less than 1% of the polymer addition amount, which can basically evaporate during the processing before vulcanization.

2. Antioxidant: The general loss amount is 0% of the added amount. 1-5, among which phenolic antioxidants are more volatile than amine antioxidants.

3. Vulcanization accelerator: Some of it is consumed during vulcanization.

4. Promoters and softeners, etc.: Heat at 167 ° C for 3 hours with a loss of 0.05 to 1.0.

5. The loss of other mixtures is 0.1.

Treatment measures: Firstly, the hot air that has been used for heating is introduced into the absorption device, where it passes through three studios. The spray cooling water passes through the air in reverse direction, the air is cooled to the dew point by insulation, and the condensed steam forms an unstable Emulsion with the spray water. The air flows through the collector and enters the heat exchanger. After heating, the relative humidity of the air decreases by below 60%, and then undergoes a layer of active substances for final treatment. After that, the content of harmful gases can be reduced from i00~800 mg/m to 20 mg/m., Spray water is recycled in closed pipelines.
