What are the characteristics of silicone defoamer
The function of defoamer is to eliminate foam in production. Silicone defoamer is a white viscous emulsion, which is widely used in many industries. Do you know what are the characteristics of silicone defoamer? The following manufacturer introduces:
The composition of silicone defoamer determines that it has the following characteristics:
(1) Different from other silicone defoamers in terms of chemical structure, the specific group is similar to non-optical, and does not associate with water, substances with hydrocarbon or optically active groups.
(2) It has stronger demulsification ability than other silicone defoamers. Generally, only 1×10-6 to 75×10-6 mass fraction of the system needs to be added to obtain good demulsification effect.
(3) In terms of physical properties, it is flexible to ordinary substances and is not easy to react with foaming substances.
(4) Silicone defoamer has good temperature resistance and high and low temperature resistance. The viscosity of methyl silicone oil increases slowly at around 200°C, but its silicon oxygen bond does not dissolve.
(5) Methyl silicone oil has excellent rigidity and wettability, so silicone defoamer is beneficial to improve the quality of coated paper.
(6) Silicone defoamer is non-toxic, environmentally friendly, and has physiological plasticity. It is a green manufacturing chemical material in this trend.
(7) Silicone defoamer is resistant to aging, has outstanding performance and anti-aging properties, and can fully exert its effectiveness under all environmental conditions.
