An environmentally friendly water scale inhibitor

Abstract

The invention relates to the field of water treatment agents and particularly relates to an environment-friendly water scale inhibitor. The environment-friendly water scale inhibitor is prepared from the following substances in parts by weight: 20-30 parts of phytic acid, 10-15 parts of ferrous oxide, 5-10 parts of glucose, 10-20 parts of maleic anhydride, 20-30 parts of sodium pyrosulfite, 25-32 parts of sodium gluconate, 15-27 parts of sodium tungstate, 30-40 parts of hydrogen peroxide, 15-30 parts of epoxysuccinic acid, 15-20 parts of calcium hydroxide, 10-15 parts of allyl polyethylene glycol monoether, 12-18 parts of beta-propiolactone, 5-12 parts of gamma-butyrolactone, 15-25 parts of vinyl-containing unsaturated double-bond carboxylic acid monomer and 45-55 parts of water. According to the environment-friendly water scale inhibitor provided by the invention, environment-friendly raw materials are adopted, the operation is simple, and the environment-friendly water scale inhibitor has a good scale inhibiting action; the used glucose and sodium gluconate are biodegradable, have an excellent scale inhibiting action and meanwhile also have a very good corrosion inhibiting action; and a polyether scale inhibitor structure contains a polyether group with high hydrophilicity and carboxylate radical ions capable of being chelated with calcium ions, so that the environment-friendly water scale inhibitor plays a role in efficiently inhibiting calcium phosphate and calcium carbonate scales of an industrial circulating cooling water system.

Description

technical field [0001] The invention relates to the field of water treatment chemicals, in particular to an environment-friendly water scale inhibitor. Background technique [0002] With the increasing attention of human beings to the living environment and the increasingly stringent environmental protection regulations, people pay more and more attention to green water treatment agents. However, the widespread use of a large number of phosphorus and nitrogen-containing scale inhibitors has caused a large number of bacteria Breeding, eutrophication of water bodies and other environmental pollution problems, therefore, it is imperative to develop green water treatment agents without phosphorus and nitrogen. [0003] For water scaling, many companies are researching source control, using resin scale inhibition, alkali scale inhibition, etc., but there are problems, such as difficult operation, labor-intensive, water quality and resin saturation at any time, and environmental p...
