Description
Technical field
The present invention relates to chemical technology field, particularly relate to a kind of circulation metal surface supermolecule and clean prefilming agent
And using method.
Background technology
The water resource of per capita of China is only the 1/4 of world average level, is the whole world country that water resource is the poorest per capita
One of, and distribution is the most unbalanced.Along with socio-economic development, the demand of water resource is got more and more by we, and is available for utilizing
Freshwater resources amount but reduce year by year due to water pollution, excessive exploitation etc., therefore, water price lattice constantly raise, country to sewage arrange
The supervision put is stricter, and advocates water for industrial use recycling.Water for industrial use recycling not only takes full advantage of
Water resource, minimizing sewage directly discharge pollution on the environment, and for freshwater resources shortage, the city of water supply wretched insufficiency
For city, it is to alleviate water resource pollution of harnessing the river not enough, anti-, the important channel of protection environment.At present, permissible after Industrial Wastewater Treatment
It is industrial cooling water as cooling water, most universality and representational purposes, in water for industrial use, the ratio of recirculated cooling water
Example has accounted for 70 % ~ 80 %, and the moisturizing using water as recirculated cooling water can actually saving water resource, minimizing sewage discharge.
But along with cooling water cycles of concentration raising, water degradation, often meeting fouling in heat transmission equipment and pipeline, affects heat exchange efficiency, with
Time, if the fouling in heat transmission equipment is serious, it is desired nonetheless to carry out replacing blowdown, occur that the phenomenon of sewage discharge occurs.How
Design a kind of reduce quantity of wastewater effluent and improve cooling water heat exchange efficiency scheme be the technical problem to be solved.
Summary of the invention
The technical problem to be solved is: provide a kind of circulation metal surface supermolecule to clean prefilming agent
And using method, clean prefilming agent by adding circulation metal surface supermolecule in circulation, it is achieved improve
The cooling water heat exchange efficiency of circulation, reaches zero burn into zero fouling, the effect of zero blowdown.
The technical scheme that the present invention provides is, a kind of circulation metal surface supermolecule cleans prefilming agent, including with
The component of lower percentage by weight: sodium alkyl benzene sulfonate 10%-15%, cyanoacetic acid 11%-15%, tetrapotassium pyrophosphate 2%-2.5%, fat
Polyoxyethylenated alcohol 4.5%-7%, disecoctylmaleate sodium sulfonate 2%-3%, phenylpropyl alcohol triazole 2%-3%, tertiary sodium phosphate 2%-
3%, ethylenediamine triacetic acid 1.5%-2.5%, silicon potassium acid 2%-3%, polyacrylic acid 2%-3%, surplus is water.
Further, also include: many polyethylene glycol oxides nonyl 2, 2-Oxydiphenol 4%～6%, para-totuidine 4%～5%, ethylenediamine triacetic acid
1%-1.5%。
Further, also include: tetrasodium salt of EDTA 3%-6%, aminotriacetic acid trisodium salt 4.5%-7%, two contractings
Propylene glycol monomethyl ether 2%-3%.
The present invention also provides for a kind of circulation metal surface supermolecule and cleans the using method of prefilming agent, and its feature exists
In, supermolecule cleans prefilming agent and uses the circulation metal surface supermolecule as described in claim 1-3 is arbitrary to clean in advance
Membrane；Described using method is: according to the adding amount L of recirculated water in circulation, fills 0.08-in circulation
The supermolecule of 0.1L cleans prefilming agent, and supermolecule cleans prefilming agent and follows the gold in circulation during recirculated water flows
Metal conduit surface forms supermolecule protecting film, meanwhile, during supermolecule protecting film is formed, metallic conduit surface
Fouling is cleaned to be separated from metallic conduit and is distributed in recirculated water, and the undissolved fouling being distributed in recirculated water also acts as biography
The effect of hot working fluid.
Compared with prior art, advantages of the present invention and good effect are: the circulation metal watch that the present invention provides
Face supermolecule cleans prefilming agent and using method, by adding Jiao in cleaning prefilming agent at circulation metal surface supermolecule
Phosphoric acid four potassium can with softening of water, improve cleansing power, take out stains, and coordinate sodium alkyl benzene sulfonate, cyanoacetic acid and fat
Polyoxyethylenated alcohol can effectively improve cleaning performance and the efficiency of metal surface fouling, and during cleaning fouling,
Phenylpropyl alcohol triazole carries out corrosion inhibition and ensures that medicament will not produce corrosion to metal surface, improves corrosion inhibition, to clean out gold
Established fouling on metal surface；After by dirt removals such as the various rust deposites of metal surface, grease, dirts, maleic acid
Di-sec-octyl sodium sulfonate, tertiary sodium phosphate, ethylenediamine triacetic acid, polyacrylic acid can be according to the feature of self microstructure at metals
Surface selectivity assembles and forms one layer of form compact and stable Supermolecular film, and many polyethylene glycol oxides nonyl 2, 2-Oxydiphenol makes supermolecule selectivity assemble
During will not destroy metal surface, owing to Supermolecular film is in the dimensional effect of microstructure, it is possible to effectively stop dirt attachment,
This effect is referred to as " according to dirty effect, " and can remove in the lump together with old dirt, it addition, the close microstructure of supermolecule protecting film,
Effectively metal surface can be modified, strengthen the corrosion resistance of metal itself.In an assembling process, the vibrations of medicament and cloth
Bright motion will make the original dirt in metal surface be removed so that it is is distributed in solution.The Supermolecular film ratio formed wears system
Passivating film, deposition film and adsorbed film will be uniform, fine and close, it is ensured that metal surface has the same anticorrosion of lotus leaf surface, according to dirty energy
Power, makes to be that metal surface is in safe and stable state.
