Drawing cold heading phosphate solution

1. Application: The phosphating agent suitable for drawing, cold heading other processes ferrous metals, but also for short storage period between steps or parts of rust phosphating. 2. Main features: 2.1 Good stability, less sediment, after a period of time just add this bonderite adjust to. 2.2 process is simple, easy to manage. 2.3 phosphate coating to a dark gray compact, continuous, uniform and no ash hanging crystals, can improve the quality of life of the mold drawing and parts. 3. Technical Specifications: Item Index Appearance light green liquid dosage (%) 7 to 15 total acidity (point) from 30 to 60 free acidity (point) 5-10 treatment temperature (℃) 65 ~ 85 treatment time (min) 6 ~ 15 Phosphate way accelerant gas dipping 0.5 point to 1.5 4. The process: After degreasing → washing → acid → washing → phosphate → washing → drying or drying saponification → → processing 5. Processing: 5.1 for wire drawing process When the Baptist saponification lubricants, temperature 60 ~ 85 ℃, time is 1 ~ 2min, after saponification treatment is not washed after drying turn the drawing process. Or short shelf life of between 5.2 parts rust phosphating process rust oil immersion only, without saponification process. 6. Configure Maintenance: 6.1 to formulate 1000L bath for example. 6.2 added first volume of the water in the tank 1/2, then add 100kgLH-62 type phosphating agent, and finally to the mark with water, stir, detection of total acidity and free acidity, if you can put into production within the process. 7. Packing and storage: 25kg, 30kg, 60kg plastic drum, stored in a cool ventilated place, shelf life of one year.
