What are the characteristics of silicone defoamer
Generally speaking, polyether silicone defoamer is converted into a variety of different initiators, silicone defoamer, and this kind of initial agent can be used as a polyether silicone defoamer. According to the basis of classification, polyether silicone defoamer can be divided into polyol type and fatty acid ester type, which are also amine ether type. These types have different characteristics. Only polyol type and fatty acid type are the most commonly used by everyone now, and they have played an important role in many industries.
The composition management of silicone defoamer determines that it has the following characteristics:
(1) The chemical structure is different from other silicone defoaming agents. The non-specific groups are similar to non-optically active and do not form associations with water or compounds containing hydrocarbon groups or optically active groups.
(2) The demulsification work is harder than that of other silicone defoamers. Generally, only the molar mass of the system is added to 1×10-6 ~ 75×10-6, and only high-quality demulsification effects can be obtained.
(3) In terms of physical properties, it is ductile to general compounds and is not likely to cause exothermic reactions with foaming compounds.
(4) Silicone defoamer has good heat resistance and high and low temperature resistance test characteristics. The viscosity of silicone oil gradually rises around 200°C, and the silicon-oxygen bond does not dissolve.
(5) Methyl silicone oil has excellent flexibility and wettability, so silicone defoamer is beneficial to improving the quality of coated paper.
(6) Silicone defoamer is safe, green and physiologically malleable, and is a trendy and fashionable smart manufacturing compound.
(7) Silicone defoamer has outstanding anti-aging, process performance and anti-aging characteristics, and its efficiency can be fully utilized under any geographical and environmental conditions.
