The use of dimethyl silicone oil is often encountered in the distress of foaming, foaming leads to ugly appearance of the product, and even odor.Not only increases the production cost, but also affects the quality of the product.Let's take a look at how to deal with the problem of dimethyl silicone oil foaming?

    What is dimethyl silicone oil?

    Dimethylsilicone oil, also known as polydimethylsiloxane, is a kind of hydrophobic silicone material.It has the characteristics of heat resistance, cold resistance, small viscosity change with temperature, water-proof, small surface tension and good thermal conductivity. 

    The cause of physical foaming:

    1. Stirring during operation

    2. Equipment speed is too fast

    3, the surrounding environment

    Chemical foaming causes:

    1, the addition of other additives to produce chemical prescriptions

    2. Raw materials of products contain foaming substances

    3, the water quality is soft

    Foaming solution:

    It has high activity due to its low solubility in water and oil in general.The chemical structure of dimethyl silicone oil has a special structure, the main chain is inorganic grade structure, non-polar molecules, so it is not soluble with water or contains polar groups of substances, so dimethyl silicone oil in water and oil solubility is low, can use a small amount of dimethyl silicone oil to obtain high activity.And the surface tension is lower than the surface tension of water, surfactant and general foaming liquid, and it is easy to spread on the surface of foaming liquid, so the ability of antifoaming is relatively strong.It has chemical stability and physiological inertness.Dimethylsilicone oil defoaming agent is chemically stable, chemically inert, difficult to react with other substances;And good thermal stability, strong defoaming ability, less dosage, but also does not affect the quality of products.So deeply customers like.
