Polyether modified silicone defoamer, polyether defoamer and silicone defoamer three are how?
Polyether Modified Silicone Defoamer
Polyether modified silicone defoamer is to introduce polyether chain on polysiloxane chain through condensation technology, so that it has the advantages of both polyether defoamer and silicone defoamer antifoam, and become a kind of antifoam agent with excellent antifoaming performance and prospects for a wide range of applications. The polyether chain segment of the polyether modified silicone can provide hydrophilicity and foaming, while the polypropylene oxide chain can provide strong hydrophobicity and high permeability, which has a strong effect on lowering the surface tension of the defoamer.
The difference between polyether modified silicone defoamer and polyether defoamer and silicone defoamer is that polyether modified silicon combines the advantages of polyether defoamer and organosilicon defoamer and is non-toxic and harmless. Polyether modified silicone defoamer is harmless to strains of bacteria and the amount added is very small. It is a cost-effective product. Polyether-modified silicone is a polyether-siloxane copolymer (referred to as silicone ether polymer) prepared from the polyether chain segment in the siloxane molecule.
Polyether Defoamer
Polyether defoamer contains special modified polyether and fluorine-containing raw materials compounded by special technology. According to these different additives, polyether defoamer can be divided into polyalcohol, fatty acid lipid and amine ether. These three different types of polyether defoamer have their own characteristics, colorless and transparent, fast defoaming and long foam suppression.
Polyether defoamer is a nonionic surfactant with excellent defoaming and foam inhibition functions, odorless, non-irritating and easily dispersed in water, etc. It is one of the most important varieties of defoamer products. Widely used in fermentation manufacturing antibiotics, vitamins and food processing, papermaking, chemical industry, paint, building materials, detergents and other areas of defoaming treatment.
Silicone Defoamer
Silicone defoamer and its main component is called silicone oil silicone components, silicone oil at room temperature is not volatile oily liquid, insoluble in water, animal and vegetable oils and mineral oils, or solubility is very small, can withstand both high and low temperatures. Chemical properties inert, stable physical properties, no biological activity.
Silicone defoamer is a white viscous emulsion. It has been used in various industrial fields since the 1960s, but the large-scale and comprehensive rapid development began in the 1980s. As a silicone antifoam agent, its application field is also very wide, more and more attention from all walks of life. In the chemical industry, paper, paint, food, textiles, pharmaceuticals and other industrial sectors organosilicon antifoam agent is an indispensable auxiliary in the production process, organosilicon antifoam agent is not only able to remove the foam on the liquid surface of the process medium of the production process, so as to improve the filtration, washing, extraction, distillation, evaporation, dehydration, drying, and other processes of the process of separation, gasification, discharge and other effects, to ensure that all types of materials, the handling of the capacity of the container. The capacity of various materials holding and processing containers is ensured.
