A little anylysis on Defoaming agent

Defoaming agent is widely used in daily chemical textile and paper industry, we introduce therelated knowledge of silicone defoamer agent:

1 hydrophobic silicon nothing: This is a very important point, because the framework of very hydrophobic, and the existence of silicon is conflict, that they don't exist any harm, but when thebypass and silicone can make a methyl group had obvious contact on the surface level also because of this, so they just miss the hydrophobic methyl group, of course, different length ofsiloxane also directly determines the hydrophobic properties of different.

2 hydrophilic surfactants and similar: of course, the most commonly used surfactant defoaming agent with hydrophilic defoaming agent has a great relationship directly, of course is similar, but the overall value of silicone defoamer agent surfactant can be directly replaced by two methyl siloxanegroup directly regulation in the past, these will directly reflect the development of the new silicone defoamer products have begun to slowly try to use the auxiliary pigment.

3 silicone defoamer exhibition strong: focus on this point before being mistaken for a wetting agent,actually this superwetting is not only dependent on surface tension decreased, of course, more important is the defoamer superwetting far more than the organic fluorine surfactant, and vice versa,organic fluorine defoaming agent than silicone defoamer is lower, its main advantages and disadvantages are occupied, so in the paint industry, the use of the additive effect will be very significant.
