Silicone defoaming agent is widely used and applied in the fermentation industry of erythromycin, lincomycin, avermectin, gentamicin, penicillin, oxytetracycline, tetracycline, tylosin, glutamic acid, lysine, citric acid, xanthan gum and so on.It is also used in textile, printing and dyeing, coating, dye, paper making, printing ink, oil field, sewage treatment and other fields.When used in dyeing and dyeing, it has good compatibility with additives in dyeing bath, and does not affect color light and dyeing fastness.

    It has been reported that organosilicon is used as a dye defoamer.The old dyeing process, generally using dimethylpolysiloxane defoaming agent, can achieve satisfactory effect of defoaming agent, and ensure the uniformity of dyeing.But the new dyeing process, the use of high temperature and high pressure machinery, in this kind of machinery, dyed by the dye liquid jet and movement, at the same time dyeing.Although the foam can be defoamed by ordinary silicone defoaming agent, but under high temperature and high pressure, the general siloxane defoaming agent will produce thin film precipitate and stain the matter.The use of block copolymers can overcome the above shortcomings, because these antifoaming agent components are soluble in cold water, but not in hot water, so they can play an antifoaming role.However, the defoaming effect of the copolymer defoaming agent alone is not satisfactory. If a certain amount of fog-like SiO2 is added to the copolymer, satisfactory defoaming effect can be achieved and evenly dyed fabrics can be produced.Used for defoaming polyester fabric in high temperature dyeing process and fermentation process.In addition, can also be used for diethanolamine desulfurization system of defoaming and a variety of oil, cutting fluid, non-freezing liquid, water-based ink system of defoaming, also suitable for printing industry photosensitive resin plate making, washing off the uncured resin defoaming, is a very representative, excellent performance, a wide range of uses of silicone defoaming agent.
