New environmental protection passivating agent, aluminum passivation solution

1, the product uses: The strains replace chromium and phosphate environmental pretreatment liquid applied to aluminum aluminum die-casting aluminum, zinc alloy, iron, non-toxic and environmentally hazardous substances before treatment products, at room temperature workpiece spraying or soaking in a dense surface to form a uniform film for coating the bottom. 2, the shape of the product: Colorless transparent liquid weakly acidic. 3, the product composition: mainly composed of silicon compound, an organic acid, acetic acid and trace zirconium material composition, does not contain any toxic substances. 4, the use of technology parameters: concentration: 1.0 - 2.0% Processing temperature: room temperature Processing time: 2 minutes to 4 minutes, PH value control: 2.0-2.8 Conductivity: 1200--3000us / cm 5, process: the workpiece → degreasing → washing → washing → passivation (2-4 min) → washing → washing drying (80-160 ℃) → spraying 6, wide applicability of the product: no water quality requirements, covering almost all of the various properties of the powder. Wide process management, less consumption. 7, the horizontal line passivation gas tank should be added and stirred. 8, after the bath used for a period of time, will produce turbidity, stationary bath surface layer of jelly-like substance, is a normal phenomenon, does not affect the results. 9, profiles treated surface pitting-like spots, is a normal phenomenon.
