Description
Technical field
Field is made the invention belongs to defoamer, and in particular to a kind of efficient rubber defoamer.
Background technology
In necks such as oil-gas mining, pulping and paper-making, textile printing and dyeing, biofermentation, sewage disposal, coating processing and building industry
Domain, the problems such as foam that stirring is produced can cause production capacity decline, extension reaction time and wastage of material.Adding defoamer can be short
Foam is eliminated in time.Defoamer can be divided into mineral oil antifoam agent, polyethers defoamer and organic silicon defoamer etc..Mineral oil
Defoamer can only, contained surfactant foaming capacity smaller in fluid shear it is relatively mild under the conditions of use, to dense form
The elimination ability of foam is poor.Polyethers defoamer competence exertion froth breaking only when the temperature of foaming system exceedes cloud point temperature
Effect.In recent years, organic silicon defoamer is received significant attention because defoaming effectiveness is high, consumption is few, physiological-toxicity-free, but organic
Silicon bad dispersibility, it is difficult to emulsify, is easily condensed into no defoaming activity, the oil droplet that granularity is excessive, and pure silicon oil is to the aqueous solution
Foam is acted on without froth breaking.
In the production technology of rubber, in latex polymerization and last handling process, because having foaming capacity stronger in system
Organic substance, a large amount of foams of generation can make troubles production, especially in post-processing step, a large amount of foam meetings of generation
The normal operation of the processes such as degassing recovery and wastewater treatment is hindered, therefore is badly in need of adding defoamer in this step causing production
Can normally it go on.Because defoamer has stronger selectivity, it is standby that commercially available common defoamer can not meet rubber system
Froth breaking requirement in technique, therefore it is badly in need of a kind of defoamer being specifically applied in various material rubber production technologies.
