What is the self emulsification defoaming agent and silicone defoaming agent?

A new self emulsification defoaming agent

Polysiloxane containing special modification. Has excellent heat resistance and corrosion resistance and chemical stability, can be widely used in harsh system of bubble elimination in a wide temperature range and inhibition.

Silicone defoaming agent

Polysiloxane defoamer usually consists of two methyl siloxane and poly silicon dioxide two maincomponents of proper fit, with two polydimethylsiloxane as substrate of defoaming agent is the elimination of defoaming agent is a kind of ideal of the global system, because it is not difficult todissolve in water, emulsion, poly two methyl siloxane surface the performance of low carbonhydrocarbons, so the surface activity is usually used in the textile industry in the agent with lower surface tension. A simple two polydimethylsiloxane defoaming performance is poor and slow, the defoaming action needs to strengthen the silica particles, silica particles were brought to the airfoam silicone oil / water interface and enter the bubble film due to its hydrophobicity, and surfactant foaming droplet contact angle greater than 90 degrees, thereby forcing the foaming liquid line from the surface of the solid particles caused by the hydrophobic, foam drainage and local rapid rupture,so, due to the synergistic effect, two kinds of material has good defoaming effect. Silicone defoaming agent because of global performance and other advantages of high, has been widely used in many fields, especially in the dyeing and finishing of textile fabrics, particularly the rapid development, the study found, the copolymer of poly two methyl siloxane and polyethylene glycol as the substrate of the silicone defoamer, due to special solubility, in jet dyeing and other textile processing, has gooddefoaming effect.
