Defoamer.The invention still further relates to the preparation method of the stable fatty alcohol emulsion defoamer of this water-soluble homopolymer.
Background technology
In many commercial production, it is necessary to process its component and there is aqueous solution and the aqueous suspension of formation of foam tendency,
Reason is that the formation of foam can make production be difficult to most probably.According to analysis, foam is many merged by bubble after be permanently formed,
Introduce the air in these systems with the stable form of fine dispersion to be proved to be also problematic in that.Therefore, these systems are reduced
In air content the most particularly significant.
At present, froth breaking operation is many to be completed by defoamer, and conventional defoamer is chyle fat alcohol defoamer.
It is thermodynamically non-stability system due to emulsion, when the most above-mentioned fatty alcohol emulsion defoamer stores after the production
And user is when keeping, it is easy to phase separation of emulsions occurs, generates the phenomenon such as gel cake mass and thickening.These are existing
As making defoaming effect reduce, producing harmful effect, and the faults such as defoamer pump can be caused, thus reduce use value, impact surely
Fixed produce, even result in the results such as product quality reduction produced in concerned process steps, bring the biggest loss.
To this end, industry has had taken up various measure, to obtaining a stable emulsion that can store for a long time.Example
As, emulsion aqueous phase is allocated into the water soluble polymers of acrylic acid, methacrylic acid, acrylamide or Methacrylamide or is total to
Polymer, polyacrylic slaine and/or ammonium salt, microbial polysaccharide class, poly(ethylene oxide), xanthan gum, methylcellulose etc..
But, the aforementioned method adding stabilizer in emulsion still cannot obtain being separated of gratifying emulsion
Less, thickening and gel is few, stability is high effect.
