Abstract
The invention relates to an environment-friendly non-phosphorus pretreatment filming agent which comprises a starch graft copolymer, a terpolymer, zinc sulfate and concentrated sulfuric acid. The pretreatment filming agent disclosed by the invention has the characteristics of environmental protection and no phosphorus, cannot cause eutrophic hazard to the natural water; the used polymeric monomer is selected from the natural product starch and easy to degrade. The pretreatment filming agent disclosed by the invention is suitable for cleaning and pre-filming of a circulating cooling water system and an air conditioning condensing system. In the application process, the green non-phosphorus pretreatment filming agent has the advantages of high cleaning speed, good cleaning effect, high film forming speed, compact and uniform film forming, low corrosion rate, and the like.
Description
Technical field
The invention belongs to the auxiliary agent for water treatment field, be specifically related to the without phosphorus prefilming agent of a kind of green.
Background technology
In the preprocessing process of water treatment, prefilming agent can be pre-formed in metallic surface a class pharmaceutical chemicals of protective membrane.The purpose of pre-film is to use chemical to suppress the initial stage of corrosion; to carrying out after matting the fresh metal surface in active state after especially pickling; or its protective membrane once was subject on the metallic surface of great damage, generated in advance the corrosion-resisting protective film of the Bao Ermi of intact before the normal operation of equipment investment.
Water treatment formulating work both at home and abroad at present mainly lays particular emphasis on normal water and surely fills a prescription, and to the report of water treatment basic components seldom, the pre-film formulation of most cleaning adopt poly-phosphate as Sodium hexametaphosphate 99 etc. as prefilming agent, phosphorus content is high, easily resolve into environment water is caused to eutrophic ortho-phosphoric acid, although occurred afterwards that the application stability of polyphosphoric acid (salt) prefilming agent improves relatively, still existed the harm of eutrophication.In recent years, the body eutrophication problem is day by day serious, and phosphorus is as the nutrition source of microorganism, and its negative impact to environment also is familiar with by people gradually, low-phosphorous or also more and more higher without the cry of phosphatization to water treatment agent.Various countries launch respectively phosphorus content in policy limiting emission water.
Summary of the invention
Comply with development, the invention provides the without phosphorus prefilming agent product of a kind of green, this product is without phosphorus can not cause the eutrophic harm of phosphine to natural water, and polymerization single polymerization monomer used is easily degraded for being selected from natural product starch.Water treatment prefilming agent of the present invention is applicable to the industrial cycle cooling system that pH value is 6 ~ 7, the pre-film of cleaning of air conditioner condensation water system etc., and the few 300 ~ 500mg/L of usage quantity, effect is remarkable.
Fine or not audient's multifactor impact of the pre-film effect of prefilming agent, topmost calcium ion concn, pH value, turbidity, other metal ion are as Al
3+, Cu
2+deng.The present invention has added terpolymer in the prefilming agent component, and by it, good copolymerization coordinates calcium carbonate in can well scale inhibition dispersion system water body, calcium phosphate, calcium sulfate etc., forms the more stable adsorption film of skim in metallic surface simultaneously; Contain a large amount of oh groups in starch structure and can be good at being attached to small suspended substance surface with the olefin-copolymerization with carboxylic acid structure it is adsorbed to dispersion, reduced the impact of turbidity on pre-film effect.Starch graft copolymer, terpolymer, three kinds of main ingredients of zinc sulfate have good synergistic effect, make metal surface protection film even compact more.
