Abstract

The present invention provides a kind of environmentally friendly corrosion inhibiting and descaling agent, it is characterised in that according to the mass fraction, including following components：Zinc oxide 2~12%；Sodium hydrate aqueous solution 15~25%；BTA 1~3%；The acryamidopropanesulfonic acid analog copolymer 20~40% of 2 methyl of acrylic acid 2；Acid antisludging agent 1~3%；Distilled water 10~25%.Product of the present invention is without phosphorus product, with the good feature of environmental protection, it is avoided that the eutrophication problem of the water quality caused by the discharge of phosphorus, alleviate environmental pollution, the breeding of microorganism is substantially reduce the number, the processing cost of Biocidal algae-killing agent can be reduced, is particularly suitable for producing the high water quality of content of organics such as methanol, ethanol, not only can corrosion-mitigation scale-inhibition, also reduce the burden of bactericide.

Description

A kind of environmentally friendly corrosion inhibiting and descaling agent
Technical field
The present invention relates to the preparing technical field of corrosion inhibiting and descaling agent, more particularly to a kind of environmentally friendly corrosion inhibiting and descaling agent.
Background technology
Anti-incrustation corrosion inhibitor is made up of organic phosphine, excellent copolymer and copper inhibitor etc., is all had to carbon steel, copper and copper alloy There is excellent corrosion inhibition, the scale inhibition and dispersion performance for having brilliance to calcium carbonate, calcium phosphate.This product is mainly used in open type circulating cooling Water treatment system, the system of cupric equipment is particularly suitable for.This product can be used for high pH, high alkalinity, the water quality of high rigidity, be current One of water treatment agent of comparatively ideal uncomfortable pH alkaline operations.
According to ten, water and the regulation of new environmental law, it is desirable to which recirculated water uses phosphate-free corrosion inhibition antisludging agent, to phosphorus in sewer Emission request reaches one-level drainage requirement, due to not containing phosphorus in sewer, reduces the amount reproduction of microorganism in recirculated water, So as to reduce the processing cost of recirculated water, sewage treatment expense can be so greatly reduced.
The content of the invention
It is an object of the present invention to overcome the above-mentioned technical problems, and to provide a kind of environmentally friendly corrosion inhibiting and descaling agent, can solve State technical problem.
The technical scheme for solving above-mentioned technical problem is as follows：
The present invention adopts the following technical scheme that to solve the above problems：
A kind of environmentally friendly corrosion inhibiting and descaling agent, according to the mass fraction, including following components：
Zinc oxide 2~12%；
Sodium hydrate aqueous solution 15~25%；
BTA 1~3%；
