Application in air cooler metal wet curtain.
Background technology
The development of human culture is exactly the development course of material, and the appearance of metal material has significantly promoted human material civilized
Progress, but the etching problem for the metal material surface widely applied in human lives also causes huge damage to human society
Lose.Corrosion can make part performance depreciation, precise decreasing, surface irregularity, the lost of life, or even scrap.According to statistics, in industry
Change country, every year because corrosion and caused by maintenance or change product expense account for the 5% of national income.Therefore, the anti-corrosion of metal
Handle significant.
Research wherein to anti-corrosion of metal processing has continued many years.Traditional chromium base anticorrosive paint includes water-based resin
And chromate etc..Because there is chromate high toxicity and carcinogenicity sternly to have been prohibitted the use of.
In addition, various chromium-less corrosion-inhibiting coatings also emerge in an endless stream, chromium-less corrosion-inhibiting coating generally comprises the amine key of carbon two, organic
Silicon or inorganic silicon etc., general such a coating, in coating than in the case of relatively thin, its antiseptic property is poor, cohesive force deficiency.
Take appropriate method to prevent metal erosion for the reason for metal erosion, the inside group for changing metal can be used
Structure is knitted, manufactures various corrosion resistant alloys；In metal surface protective mulch, make metallic article and surrounding corrosive medium every
From so as to prevent from corroding and using electrochemical protection method, metal oxide layer is covered in metal surface.But these traditional metals
