The silicone pad is a relatively common type of silica gel products, odor, vulcanized smoke blue smoke emitted during the vulcanization process when the state has a special intolerable complex component, specific conditions of its components, the amount depends largely on the formulation and curing time. Vulcanization is still the most important operation procedure for producing silica gel products. All kinds of composite components will only change the performance. Of course, using accelerator can make mass production possible. Interestingly, even if the vulcanization has been known and used for more than 150 years, the basic process has hardly changed.

When the rubber vulcanization release of volatiles are the following, the residual monomer in the polymer: General dosage polymer L, in the process before vulcanization can basically evaporate; antioxidant: general loss is the amount of O.1 ~ O.5, the phenolic antioxidant is amine antioxidant volatile; accelerator: in vulcanization part consumed; accelerant and softeners etc. in the heating: 167 "C 3 hours under the loss of 0.05 to 1; the loss of other complexing agent was 0.1.

The recommended operation measures for experienced operators: the first is the heated air inlet and absorption device which has been worked before, and there have been past three workshops. The cooling water and air through the air by reverse spraying, adiabatic cooling and condensing the steam to the dew point, with the formation of unstable emulsion spray water. The air flow through the collector into the heat exchanger, air after heating, the relative humidity decreased sapidissima below 60, then through a layer of active material of Sheng final treatment, content of harmful gases after the beginning of the i00~800 by Sheng mg / m to 20 mg / m.

Silicone pad products can be through the different curing technology, the four most commonly used methods of natural heat vulcanization briefly summarized as follows: in the mold under steam or electric heating plate in hydraulic 'daylight' news; in the press, in autoclave was completely surrounded by steam; wrapped in a cloth, or embedded in an inert such as powder, talcum powder, live steam under pressure; the so-called "open steam therapy"; in the hot air, at atmospheric pressure or under elevated pressure, "dry" curing method.
