Description
Technical field
More particularly to it is a kind of for the without phosphorus multiple of industrial circulating water the present invention relates to the water technology in chemical field
Close anti-incrustation corrosion inhibitor and preparation method thereof.
Background technology
The situation is tense for China's water shortage, and the huge industrial water of consumption, is faced with serious challenge with necessarily standing in the breach.And
In industrial water consumption, cooling water account for very big ratio.Industrial colling accounts for the 80-90% of industrial water, and industry repeats to use
The utilization rate of water only accounts for 20-30%, is the 1/3 of developed country.Therefore, the operation and management gesture for strengthening industrial circulating cooling water exist
It must go.
Measures of Saving Water relatively conventional at present is that recycling, industrial water circulation is made by cooling water after certain processing
It is real reliable Industrial Water Saving measure with instead of original direct current water.
Whole circulation operationally, often produces various problems, such as circulatory mediator to various metallic conduits
And the corrosion of heat exchanger, water are constantly evaporated, concentrated in the process of running, water intermediate ion concentration improves, in heat exchanger surface fouling,
Mattress algae growth etc. in system.These problems influence system operation, can trigger all kinds of security incidents when serious.
General solution is exactly to add chemical agent, such as anti-incrustation corrosion inhibitor, Biocidal algae-killing agent, adhesive mud remover.
Most commonly seen anti-incrustation corrosion inhibitor is phosphorous medicament, has certain effect to preventing incrustation scale and metal erosion, but phosphorus system medicine
Agent long-time service generates the problem of new again, and total phosphorus have received a fixed limit in sewage discharge
System, while a large amount of uses of phosphorous medicament, have aggravated body eutrophication.
The content of the invention
In order to solve the fouling of prior art recirculating cooling water system, etching problem, first technical solution of the invention is to carry
For a kind of non-phosphorus scale and corrosion inhibitor, second technical solution is to provide a kind of preparation method of non-phosphorus scale and corrosion inhibitor.
Realize that above-mentioned purpose uses following technical scheme：
A kind of non-phosphorus scale and corrosion inhibitor, is made of the raw material of following mass parts：10-20 parts of polycarboxylate, polymer-amino-acid
15-30 parts, 10-15 parts of zinc salt, 10-15 parts of sodium salt, 1-2 parts of copper inhibitor, 10-20 parts of sulphonic acids polymer, surplus is water.

Step 5：
Blowing after sampling, detection are qualified, labelling, storage.
It is compared with prior art, efficient present invention is mainly used in recirculated cooling water, having using above-mentioned technical proposal
Scale inhibition effect, usage amount is few, environmentally safe, and the adsorbed film and precipitation membrane that can be formed in metal surface play corrosion inhibition,
At the same time have to the calcium carbonate in water, calcium phosphate, calcium sulfate etc. good chelating disperse and distortion of lattice effect, prevent all kinds of dirts
Formation, ensure that system normal operation.In addition the manufacture of the without phosphorus medicament of environment-friendly type and using process, to health and
Environmental security influence is smaller, will not cause body eutrophication, meet the requirement of sustainable development and advocating for Green Chemistry,
New Environmentally-friephosphorus-free phosphorus-free water treatment agent is researched and developed to have important practical significance.
