Technical background
Corrosion and corrosion protection is related to Economic development and people's life safety, and surface engineering technology is to solve component of machine and material corrosion and most economical effective means of protection and method.
Zinc-plated and zinc-iron alloy is the effective way that improves the steel-iron components resistance to corrosion, is widely used at present in many fields such as shipbuilding industry, mechanical industry, aviation, building.But in a humid environment, especially in hygrothermal environment, zinc-plated and zinc-iron alloy layer easily corrodes, and makes coating surface form corrosion product---the white rust of lead or white loose; Time has been grown and red rust can occur, thereby loses preservative effect.In order to improve the solidity to corrosion of coating, must carry out Passivation Treatment to coating and form surface passivated membrane.
Nearly all steel plate galvanized aftertreatment technology has all adopted the chromating processing at present, but owing to sexavalent chrome toxicity in the chromic salt is high and easily carcinogenic, government's strictness limits using and discharging of chromic salt; And emphasize in the Eleventh Five-Year Plan that a development environment resist technology gives priority to.Therefore the chromating technology is faced with severe challenge, and seeks and adopt the chromium-free deactivation technology of compliance with environmental protection requirements just becoming the inexorable trend of present development.Chromium-free deactivation on the at present both at home and abroad zinc-plated and alloy layer mainly contains molybdate passivation, rare earth metal passivation, silicate passivation, phytic acid passivation and organism passivation etc., but the solidity to corrosion that the passivation effect of these chromium-free deactivation technology does not also reach chromating to be had, or expense is too high, to such an extent as to also there is not a kind of non-chromium inactivating technique to replace chromating technology fully at present, clean accordingly, passivating solution technology low-cost, good passivation effect do not have yet.
Summary of the invention
The objective of the invention is to overcome the deficiency that has passivating technique in zinc-plated and the zinc-iron alloy now, provide a kind of do not contain Toxic matter, electro-galvanizing that the product performance of handling are good, production cost is low and zinc-iron alloy clean purification liquid of silicate, be used for the component of electro-galvanizing and zinc-iron alloy are carried out aftertreatment, to improve the solidity to corrosion of component.
