Description
Technical field
The present invention relates to chemical industry preparation technique fields more particularly to a kind of high efficiency defoaming agent and preparation method thereof.
Background technique
Foam may be defined as the gas being stabilized in liquid medium.In latex, textile sizing, food fermentation, biology doctor
Many unwanted bubbles can be generated in the commercial process of the industries such as medicine, pesticide, coating, petrochemical industry, papermaking, and then are influenced
Plant capacity causes the waste of raw material, extends reaction time, influences product quality etc., therefore often needs that defoaming is added
Agent is generated with achieving the purpose that be reduced or avoided bubble.
Defoaming agent can be divided into two kinds of approach of foam inhibition and brokenly bubble from intreractive theory, and foam inhibition refers to inhibition bubble as its name suggests
The generation of foam, that is to say, that the favorable factor that foam generates is eliminated from source, and brokenly bubble refers to that the foam that will have been generated is abolished,
To have the function that reduce foam.Two kinds of defoaming modes of defoaming agent can all play the role of effectively controlling bubble amt, therefore
Important function is all had in actual production.
