Silicone Defoamers Use And Widely Used In Erythromycin

Jun 15, 2017

  Silicone defoamers use and widely used in erythromycin, lincomycin, avermectin, gentamicin, penicillin, oxytetracycline, tetracycline, tylosin, glutamate, Amino acid, citric acid, xanthan gum and other fermentation industry used as defoamer. Also used in textile, printing and dyeing, coatings, dyes, paper, ink, oil, sewage treatment and other fields. When used in printing and dyeing, and dye bath additives have a good compatibility, and does not affect the color and color fastness.

  Silicone used as a spray defoamer, has been reported in many literature. The old dyeing process, the general application of dimethyl polysiloxane defoamer, can achieve a satisfactory defoamer effect, and to ensure uniform dyeing. But the new dyeing process, the use of high temperature and high pressure machinery,Silicone defoamer in this machine, the dye was sprayed by the dyeing liquid movement, while being stained. Although the resulting foam can be defoamed by ordinary silicone defoamers, but at high temperature and pressure, the general silicone antifoam will produce a film-like precipitation and the stains generated spots. The use of block copolymers can overcome these shortcomings, because these defoamer components can be dissolved in cold water, and insoluble in hot water, it can play a defoaming effect.Silicone defoamer But only with this copolymer defoamer defoaming effect is not satisfactory, if the copolymer by adding a certain amount of mist SiO2, you can achieve a satisfactory defoaming effect,Silicone defoamer and produce a uniform dyeing fabric The For polyester fabric high temperature dyeing process, fermentation process in the defoaming. In addition, it can also be used for defoaming of diethanolamine desulfurization system and defoaming of various oil, cutting fluid, antifreeze, water-based ink and so on. It is also applicable to the printing industry. Bubble, is a very representative, excellent performance, widely used silicone defoamer.
