Technical Field
The invention belongs to the technical field of chemical industry, and particularly relates to a defoaming agent.
Background
Defoamers, also known as defoamers or foam breakers, generate a number of foams during industrial production that affect production and require the addition of defoamers. The method is widely applied to removing harmful foams generated in the production processes of industries such as latex, textile sizing, food fermentation, biomedicine, coating, petrochemical industry, papermaking, industrial cleaning, sewage treatment and the like.
However, many of the conventional commercially available defoaming agents have problems of low defoaming speed and poor defoaming effect.

Further, the composition comprises the following components in parts by weight: 30 parts of sodium polysilicate, 70 parts of water glass, 8 parts of polyvalent metal salt, 40 parts of water, 24 parts of dimethyl silicone oil, 7 parts of polyether, 3 parts of paraffin, 10 parts of emulsifier, 8 parts of fatty alcohol, 10 parts of polydimethylsiloxane, 2 parts of potassium iodide, 15 parts of boric acid, 15 parts of isopentenol, 12 parts of tertiary pentane chloride, 4 parts of mineral oil and 10 parts of fatty acid.
Further, the composition comprises the following components in parts by weight: 40 parts of sodium polysilicate, 90 parts of water glass, 12 parts of polyvalent metal salt, 50 parts of water, 28 parts of simethicone, 8 parts of polyether, 4 parts of paraffin, 13 parts of emulsifier, 10 parts of fatty alcohol, 13 parts of polydimethylsiloxane, 4 parts of potassium iodide, 20 parts of boric acid, 25 parts of isopentenol, 16 parts of tertiary pentane chloride, 5 parts of mineral oil and 16 parts of fatty acid.
By adopting the technical scheme, the invention has the following beneficial effects:
(1) the invention has strong defoaming capability, and can effectively eliminate foam when used in a very small amount; has lower surface tension than a system to be defoamed and has good surface tension balance; the basic performance of a defoamed system is not influenced after the defoamer is added; is insoluble in a defoaming system and is not easily solubilized by a surfactant in the system; the defoaming agent does not react with a defoamed medium, is not decomposed and degraded by the defoamed medium, and has good chemical stability; the foam has good diffusivity and permeability, positive diffusion coefficient in a foam medium and quick spreading capacity on the surface of the foam; the heat resistance is good, and the efficacy can not be lost at high temperature; the gas solubility and permeability are good; the defoaming agent has high physiological activity and safety in a defoamed system, and the defoaming agent is a non-toxic or low-toxicity substance; has good storage stability; has long-term defoaming effect.
