Description
Technical field
The invention belongs to field of fine chemical, and in particular to a kind of outdoor machine of air-conditioner cleaning anti-rust agent.
Background technique
In the modern life, air-conditioning almost has become daily necessities.And the outer machine equipment of air-conditioning is chronically at exposure
Wind and rain environment in, as time goes by inevitably generate rusty stain, miscellaneous dust and dirt.And the accumulation of rusty stain and miscellaneous dust and dirt will
The heat dissipation effect of the outer machine of serious influence, reduces air-conditioner efficiency.Miscellaneous dirt will be removed in time at this time, equipment is maintained to operate normally.
It is existing to there are mainly two types of outdoor machine of air-conditioner dedusting methods, Mechanical Method and chemical method.Mechanical Method is to rub and wind-force
Based on cleaning, but outdoor machine of air-conditioner is essentially hung upon high building exterior wall, and artificial friction can not touch the groove, side of its pipeline and cooling fin
Angle place, and the safety of construction personnel can not ensure；Chemical method be rinsed using the external machine of detergent solution, and it is existing often
The cleaning agent of rule is generally all containing the acid based on hydrochloric acid, organic acid, also usually when removing miscellaneous dirt using cleaning agent
The metal structure of outer machine can be corroded.Contain citric acid in patent CN201710510819.6 as cleaning agent, although to environment friend
It is good, but removal of impurities dirt effect is unobvious, especially thicker miscellaneous knoisphere can not be removed effectively；Patent CN201310112660.4 is related to
And cleaning agent contain salt sour component, removal of impurities dirt is high-efficient, but the damage of the metal surface of the external machine of hydrochloric acid is big, and hydrochloric acid is easily waved
Hair, influences operator's health and is unfavorable for air environment.
Of the invention focuses on high-efficient rust-removing scale removal, and clean surface surface forms protective layer, prevents clean surface reoxidized.
Summary of the invention
Outdoor machine of air-conditioner cleaning anti-rust agent in the present invention is in terms of weight fraction.To realize derusting effect, moderate strength is selected
Tartaric acid and citric acid, be used alone or the two be used in mixed way so that rusty stain remove.Rusty scale is invaded in order to improve simultaneously
Erosion ability is wherein adding a small amount of sodium chloride, and the chloride ion content appropriate that improves can effectively enhance the dissolubility of rusty stain.For
The dust and dirt of appearance, sulfamic acid and sodium pyrophosphate are scale remover of good performance, and the two, which can be used alone or mix, to be made
With.It is properly added fatty alcohol polyoxyethylene ether (AEO-14) or organic acid can be improved to rusty scale in isopropanol wetability, AEO-14
Belong to nonionic surfactant, there is good wettability to metal oxide, and do not influenced by pH value, effectively will
Rusty stain package, brings into solution, accelerates the infiltration of cleaning agent, and isopropanol can accelerate organic acid to metal rusty stain contacting permeation,
Shorten the derusting time；In order to improve the compatibility of the rusty stain to fall off and dust and dirt in cleaning agent, even phase agent appropriate is must can not
Few, one of cetyl benzenesulfonic acid sodium and dodecyldimethylamine oxide or mixed liquor can be selected, is conducive to solid
The stabilization of body particle in water.
Outdoor machine of air-conditioner after rigid rust removing and contaminant releasing is easy to return rust with remaining organic acid agent in the case where ingress of air,
In order to reduce clean surface re-oxidation, antirust component is added in cleaning anti-rust agent: three nitrogen of hexa or benzo
Azoles, individually or the two is used in mixed way, and the lone electron pair on distinctive nitrogen can be complexed with the d track of metal, in metal watch
Face forms hydrophobic molecule organic layer, and anti-rust action is played in the infiltration of starvation；Sodium nitrite has powerful reproducibility,
It can prevent metal from aoxidizing the hydrogen reduction of infiltration.Dextrin can form monolayer high polymer, the infiltration of isolating oxygen in metal surface
Thoroughly.
Outdoor machine of air-conditioner cleaning anti-rust agent in the present invention, the beneficial effect is that acid solution is not waved under the premise of high-efficiency washing
Safety and environmental protection is sent out, avoids outdoor machine of air-conditioner clean surface from being reoxidized in addition, being quickly generated protective film；And in surfactant
Under effect, cleaned dirt is uniformly dispersed, and can easily clean removing.
