Passivating agents
One component passivator
ZY-301-IIB passivating agent instructions
一、 Product Introduction:
推出New single-component passivation solution为High strength adhesive,It is not precipitated, always contained in the liquid, hung on the surface of the galvanized parts during passivation, the thickness of the passivation film is increased, the anti-corrosion effect is good, and the slag is significantly less than the old passivation liquid。Effectively ensure the passivation liquid quality stability
After passivation of the product, the passivation film is colorless, bright and strong corrosion resistance。With tank liquid stability, easy maintenance, reduce emissions, conducive toEnvironmental protection。
用途:Suitable for post-treatment passivation of various galvanized products, effectively prevent white embroidery and black spots on the surface of galvanized products, and increase the corrosion resistance of metal。
2. Operation guidance and process parameters:
1.Liquid dispensing ratio: galvanized sheet 1:9, plating other components 1:30;That is, one kilogram of passivation liquid is added to 9 kilograms or 30 kilograms of pure water;After passivation不漂洗。
2.Consumption: Galvanized sheet 0.35g/㎡, spray pipe 1.2g/㎡。
3.Operating temperature: 10-50℃。
4.比重:1.10-1.18
5.Chromic acid point: 14-20。
6.Passivation time: 1-25 seconds
Seven.Preparation water: conductivity should be less than 200µs/cm of deionized water。
Iii. Precautions:
1. The passivation effect of galvanized pipe is best by spraying。
2. 热The effect of roller coating is the best, followed by spray extrusion and finally immersion。
3. 热Wire passivation of galvanized sheet must be dried before winding, so as to ensure that the sheet has good corrosion resistance, it is recommended to use80-130℃The hot air blows dry to reach50-80℃The metal surface temperature。
4. Impregnation of structural parts: plus30-35Double water does not rinseAdd adjustment solution and use repeatedly。
5. Passivating product warpAfter 24 hours of reaction, a reliable and stable corrosion resistant skin film is formed, and then the corrosion resistance is the strongest。
