How to deal with foaming of dimethyl silicone oil?
The common problem encountered when using dimethyl silicone oil is foaming, which can lead to unsightly appearance of the product and even produce an unpleasant odor. Not only does it increase production costs, but it also affects product quality. Let's take a look at how to deal with the problem of foaming of dimethyl silicone oil together?
What is dimethyl silicone oil?
Dimethyl silicone oil, also known as polydimethylsiloxane, is a hydrophobic organic silicon material. It has the characteristics of heat resistance, cold resistance, low viscosity change with temperature, waterproofing, low surface tension, and good thermal conductivity.
Reasons for physical foaming:
1. Mixing during operation
2. The device speed is too fast
3. Surrounding environmental impact
Reasons for chemical foaming:
1. Other additives added generate chemical reactions
2. The raw materials of the product contain substances that are prone to foaming
3. Soft water quality
Bubble solution:
Due to its low solubility in water and general oil, it has high activity. Dimethyl silicone oil has a special chemical structure, with an inorganic main chain and non-polar molecules. Therefore, it is insoluble in water or substances containing polar atomic groups. As a result, dimethyl silicone oil has low solubility in water and oil, and can achieve high activity with a small amount of dimethyl silicone oil. Moreover, the surface tension is lower than that of water, surfactants, and general foaming liquids, making it easier to spread on the foaming surface, resulting in stronger anti foaming ability. Has chemical stability and physiological inertness. Dimethyl silicone oil defoamer has stable chemical properties, is chemically inert, and difficult to react with other substances; And it has good thermal stability, strong defoaming ability, low dosage, and does not affect product quality. So it is deeply loved by customers.
