Description
Technical field
The present invention relates to a kind of metalwork composite anti-corrosive processing technology field, especially a kind of alloy permeation and Dacroment are multiple
Close corrosion-inhibiting coating preparation method.
Background technique
Annual world steel corrosion loss accounts for 10% or more of steel total output, economy caused by industrially developed country corrodes
Loss accounts for 2%~4% of total value of production in national economy or more；Advanced anticorrosion technique is researched and developed, is passed through caused by corrosion with reducing
Ji loss, the service life for extending steel and other metal materials and equipment, to promotion advanced technology, the most advanced branches of science and national defence work
The sustainable and harmonious development of the development of industry and national economy and social environment has particularly important meaning.
Multi-component alloy co-cementation is novel anti-corrosion of metal technology, mainly passes through and carries out complicated physics under vacuum conditions
Chemical reaction, and then a corrosion protective layer in homogeneous thickness, surface hardness is high is formed in metal surface；Multicomponent alloy is total
It seeps insufficient for the resistance to corrosion of salt fog gas.
Dacroment also known as reaches a gram rust, high gram rust, Zinc-Chromium film etc., refers to use and contains zinc metal sheet, aluminium flake, chromic anhybride, ethylene glycol
The liquid treatment fluid of equal ingredients coats metallic matrix, after high-temperature baking, has at one layer of metal base surface formation splendid
Corrosion proof non-decoration film, existing deficiency are surface hardness deficiency.Further, since chromium is anti-in Dacromet/steel metal
Key effect is played in rotten technology, the content in slurries is at 20~26 milligrams every liter or more, the solidification of Dacromet/steel
Journey is exactly the process that sexavalence chromic acid is restored by organic matters such as ethylene glycol at high temperature, to generate not soluble in water, unbodied
Trivalent chromium is as bonding agent, and with metal surface, tens of layers of lamination zinc metal sheet combines to form 5~12 microns finer and close of Da Ke
Sieve zinc-chromium coating；Therefore chromium all exists all the time in the processing and application of Dacroment, preparing from raw material storage and transportation to slurries,
To the coating and solidification of Dacroment, use is finally arrived, all there is the possibility of pollution of chromium.
