Background technology
Metal passivation process instigates metallic surface due to the effect of medium, and be converted into not easily oxidized state, makes the method that corrosion of metal speed delays.The passivation of metal also may be spontaneous process (as generated the insoluble compound of one deck at metallic surface, i.e. oxide film).Be industrially, with passivator (mainly oxygenant), Passivation Treatment is carried out to metal, form layer protecting film.
Steel plate galvanized is one of important preventive means of cold-rolled steel sheet, and it is widely used in the industries such as aviation, electric power, traffic, building, machinery.Zincincation is mainly divided into electro-galvanizing and pot galvanize, wherein especially relatively simple with the manufacturing process of hot-dip galvanizing sheet steel, easily produces, therefore hot-dip galvanizing sheet steel in industry and daily application also widely.Hot-dip galvanizing sheet steel is used for the history of anticorrosion existing more than 200 year, still occupies an important position so far.In recent years, along with developing rapidly of construction industry, car industry and household electrical appliances industry, steel plate galvanized obtains to be applied more widely, also has higher requirement to the solidity to corrosion of hot-dip galvanizing sheet steel simultaneously.Steel plate galvanized easily corrodes, and makes Several Thiourea Derivatives on Zinc Plate Surface easily form ash dark-coloured, forms white rust or black change, generally need to carry out Passivation Treatment to improve corrosion resisting property in storage process.
Although steel plate galvanized has had stronger anti-corrosion capability, steel plate galvanized has still easily corroded in a humid environment, forms the corrosion product of white or becomes ash dead color, have impact on visual appearance and the coating corrosion stability of steel plate galvanized on its surface.Therefore, must process in the back segment operation of zincincation, improve the solidity to corrosion of steel plate, general aftertreatment comprises: phosphatization, passivation or organic coating process.Traditional hot-dip galvanizing sheet steel, general employing passivation aftertreatment improves its corrosion resistance nature, its common medicament all contains a large amount of sexavalent chromes, and from September, 2000, the European Parliament of ELV and cabinet member board of management instruction (EU instruction) specify Pd, Hg, Cd, Cr of auto production line
6+usage quantity limited, and enforcement: WEEE (waste electrical and electronicequipment) and RoHS (restriction of hazardous substances) instruction will be received in January, 2003 Bian about the EU instruction of electric appliance and electronic product, require that the household appliances after in July, 2006 use substitute materials to replace Cr
6+.Therefore, the Passivation Treatment being used in the hot-dip galvanizing sheet steel on automobile and household appliances cannot re-use containing Cr
6+medicament, or usage quantity will be limited, and this just needs exploitation chromium-free deactivation medicament to meet the needs in market and production.
