Chengdu Branch-brand LH-7 anti-theft doors and other steel workpiece-specific phosphate solution

1. Main features: This product at room temperature, low temperature can generate dense phosphate film with good corrosion resistance, long time anti-rust powder adhesion characteristics, especially for long time anti-theft doors and other technology, high corrosion resistance of phosphate coating workpieces using 2. Scope: suitable for coating Phosphatization security doors, electrical cabinets, safes, automotive, instrumentation, home appliances and other steel workpiece with paint, spray and other Coating technology support. 3. Technical Specifications: Item Index Appearance light green liquid concentrate total acidity (point) 25 to 38 free acidity (point) 0.8 to 2 accelerator concentration (point) 1.5 to 3 treatment temperature (℃) at room temperature (0 to 45) Processing Time (min) dipping: Spray 8 to 15: 2-3 4. Process: Oil rust workpiece → conditioning → phosphating → washing → drying 5. detected and added: 5.1 for the first time with the groove. Add 1/2 tank of water, add this concentrate 100kg, add water to 1000 liters Stir for 1 to 2 hours of free sample testing to determine the acidity, total acidity Technical indicators can be added if free acidity is high neutralizer tune to the process range. 5.2 additional accelerator. Decided before each shift or per day of additional work to make accelerator index control within the process according to the working capacity. 5.3 With the increase in the work process, the bath will increase the amount of sediment should be regularly turned groove processing bath. 6. Packing and storage: 25kg plastic drum, stored in a cool ventilated place, shelf life of one year.
