Description

A kind of Compounded Antifoamer that can improve toughness

Technical field

The present invention relates to chemical material technical field, more particularly, to a kind of Compounded Antifoamer that can improve toughness.

Background technology

During commercial production, if with the presence of substantial amounts of foam, many troubles can be brought, such as in production process Production capacity can greatly be restricted；Cause the waste of raw material and product；Impact product quality；Pollution environment etc., therefore, How to efficiently control foam in production process, become researcher emphasis of interest.Typically now eliminated with defoamer The foam producing in commercial production.

Industrial conventional defoamer generally can be divided into organic defoamer, organic silicon defoamer and polyether-type defoamer etc. three Class.

Polyether antifoam agent belongs to nonionic surfactant, has excellent froth breaking, suds function, nontoxic, is insoluble in water, easily It is dissolved in organic solvent, can be used alone, also can be made into emulsion and use, wherein gpe type is particularly suitable for fermentation industry use, ppe Suitable applied at elevated temperature.This product has polyethers, the advantage of silicone defoamer concurrently, can be to different medium froth breaking, suds, and its froth breaking is imitated Fruit is stronger 2～3 times than conventional antifoam, and has that toxicity is low, surface activity is high, ph wide accommodation, surface tension are low, sprawls The features such as speed is fast.This product can be dissolved in water with arbitrary proportion, and is amenable to high temperature sterilize process, be widely used in fermentation and manufacture The field defoaming treatment such as antibiotic, vitamin and food processing, papermaking, chemical industry, coating, building materials, detergent.

Polyethet surfactant is existed with molecularity in water, and stability is high, does not have toxicity, with other kinds of surface Activating agent intermiscibility is good, and has good suds effect, emulsifying capacity and cleaning function, has been widely used in many industry The every field such as department and civilian washing.With the development of petroleum industry, polyether surfactant yield and kind are always Rising.Polyether surfactant molecular weight generally change ratio is larger, and its composition and structure are all more complicated, and these differences The physico-chemical property of polymer will significantly be changed.

In current polyether antifoam agent, such as Chinese patent database, cn 101638868 a discloses. a kind of polyethers froth breaking Agent, more complicated etc., its technological process, can not froth breaking, suds simultaneously, performance is single, is unfavorable for being promoted the use of.
