An environmentally friendly water scale inhibitor

Abstract

The invention relates to the field of water treatment chemicals, in particular to an environment-friendly water scale inhibitor. It is composed of the following 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 metabisulfite, 25 parts of sodium gluconate -32 parts, 15-27 parts of sodium tungstate, 30-40 parts of hydrogen peroxide, 15-30 parts of epoxy succinic acid, 15-20 parts of calcium hydroxide, 10-15 parts of allyl polyethylene glycol monoether, 12-18 parts of β-propiolactone, 5-12 parts of γ-butyrolactone, 15-25 parts of carboxylic acid monomer containing ethylenically unsaturated double bonds, and 45-55 parts of water. The environment-friendly water scale inhibitor provided by the invention adopts environment-friendly raw materials, is simple to operate, and has good scale inhibition effect. Good corrosion inhibition effect, polyether antiscalant structure contains highly hydrophilic polyether groups, and carboxylate ions that can chelate with calcium ions, and is highly effective against calcium phosphate and calcium carbonate scales in industrial circulating cooling water systems inhibitory effect.

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...
