Description
Technical field
The present invention relates to that a kind of industrial circulating cooling water uses, but the preparation of scale inhibitor.
Background technology
Because saltiness height in the industrial circulating water, have corrodibility and fouling tendency ion, so system exists heavy corrosion and fouling at operational process medium carbon steel, there is the deficiency of following three aspects in the anti-incrustation corrosion inhibitor of each industrial carbon steel system use at present: the one, and it is big to add dose, minimum dosage is not less than 80mg/l, general using dosage is at 120mg/l, thereby makes running cost high; The 2nd, scale inhibition ability and corrosion inhibiting ability can not consider simultaneously that the corrosion inhibiting ability that the scale inhibition ability is good is poor, the scale inhibition ability that corrosion inhibiting ability is good.The 3rd, at present commercially available carbon steel anti-incrustation corrosion inhibitor all contains a large amount of inorganic phosphorus, and water surrounding is caused the harm of eutrophication, accomplish that scale inhibition and corrosion mitigating effect all reach the medicament that adds that requirement must heavy dose.
Now Shen Qing anti-incrustation corrosion inhibitor has " a kind of composite scale-inhibiting corrosion inhibitor " (Chinese patent 0113709.5), constitute by phosphine carboxylic acid, 1-Hydroxy Ethylidene-1,1-Diphosphonic Acid, multipolymer, zinc salt, water etc., be used for recirculating cooling water system, prevent carbon steel, stainless steel, the copper equipment corrosion of recirculated cooling water fouling and recirculating cooling water system." a kind of composite scale-inhibiting corrosion inhibitor " (Chinese patent application 03126495.6) includes machine phosphonic acid, contains the phosphonate group poly aspartic acid, contains carboxylic acid-based copolymer and zinc salt, and looks particular case and the copper material corrosion inhibitor that exists." a kind of low-phosphorous composite scale-inhibiting corrosion inhibitor " (Chinese patent 200410073665.1), comprise 2-phosphonic acid butane-1,2,4-tricarboxylic acid (PBTCA) and/or 2-hydroxyethylidene diphosphonic acid guanidine-acetic acid (HPAA), zinc salt, molybdate or tungstate and contain the carboxylic acid-based copolymer.
Summary of the invention
The objective of the invention is at above-mentioned present situation, aim to provide a kind of inhibition and scale inhibition effect of having concurrently, do not contain the superloy system high efficiency anti-incrustation corrosion inhibitor of inorganic phosphorus simultaneously again.
The implementation of the object of the invention is, superloy system high efficiency anti-incrustation corrosion inhibitor is made up of following component in percentage by weight:
Organic phospho acid salt material 5%-15% polycarboxylic acid material 30%-40%
