Description

Emulsifying reactor of organosilicon water-based emulsion

Technical Field

The organosilicon water-based emulsion can be used as a defoaming agent to be widely applied to the industrial fields of papermaking, spinning, sizing agent, coating, building, leather, medicine, cosmetics and the like, and the application field is continuously expanded, so that the application potential is very high. Active substances such as organosilicon which is difficult to dissolve in water are emulsified into oil-in-water emulsion by an emulsifier, water and the like, and after a foaming system is added, the organosilicon with defoaming activity can be effectively dispersed in a water phase to fully play a defoaming role.

The organic silicon emulsion needs to consider the dilution stability, storage stability, shear resistance, compatibility, temperature resistance stability and the like of the product. If the stability of the organic silicon emulsion for specific application is not good, floating oil can be separated out, the normal operation of industrial production is seriously influenced, and great economic loss is caused. Therefore, the stability of the silicone emulsion is of considerable importance. However, the existing silicone emulsion has poor dilution stability and defoaming durability. The additive amount of the traditional organosilicon emulsion is increased when the traditional organosilicon emulsion is used, and the defoaming efficiency is reduced.

One of the reasons for this is that: the existing emulsification reactor can not sufficiently emulsify the emulsion raw material. When the stirring paddle in the existing emulsification reactor rotates for stirring, the viscosity of the material of a silicone oil emulsification system is high, so that the whole kettle liquid moves along with the stirring paddle easily, and a relatively stable stirring environment is formed, thereby reducing the shearing action of the stirring paddle. This results in the formation of individual large oil-in-water "oil bubbles" in the emulsified system, with large size differences between the oil bubbles and an unstable emulsified system.
