2020-01-07Wide application: due to the special chemical structure of silicone oil, it is neither soluble with water or substances containing polar groups, nor with hydrocarbons or organic substances containing ......
2020-01-07Polyether defoamer is a kind of defoamer widely used in recent years, and its defoaming property is good. The advantages of polyether defoamers are that they are nontoxic and convenient to use. The mo......
2020-01-07When solid and liquid contact, the original solid-liquid interface disappears, forming a new solid-liquid interface. This phenomenon is called wetting. When the pigment filler is wetted with liquid an......
2020-01-07The foam is produced by external forces, and when the air enters the liquid containing surfactant, the surfactant will be aligned at the gas-liquid interface. The hydrophobic group is toward the air o......
2020-01-07In the process of industrial production, a lot of harmful bubbles will be generated, and defoamer should be added. There are many kinds of defoamers, such as organosiloxane, polyether, grafting of sil......
2020-01-06When solid and liquid contact, the original solid-liquid interface disappears, forming a new solid-liquid interface. This phenomenon is called wetting. When the pigment filler is wetted with liquid an......
2020-01-06When the air enters the liquid containing surfactant, under the action of external force, the surfactant will be aligned at the gas-liquid interface. The hydrophobic group is toward the air of bubble,......
2020-01-06There are many factors that affect the foaming and foam stabilization in the formulation of antifoam. 1: The surface tension of the ......
