Corrosion Decorative blackening table transfers

1. Application: for ferrous metal surface is not coated corrosion resistant surface decoration before adjustment phosphate coating process. 2. Key Features: 2.1-activated parts of the surface to accelerate the formation of phosphate coating black nuclei, extend the life of phosphating solution. 2.2 improve the quality of phosphate, reducing the surface composition of alkali degreasing or acidic rust and other defects caused by uneven. 2.3 to improve the phosphate film appearance, the parts formed on the surface of black, fine, uniform phosphate crystals. 3. Main Technical Specifications: Item Index Appearance colorless transparent liquid free acidity (point) from 20 to 30 treatment temperature (℃) normal processing time (min) 2 ~ 3 4. Use dipping process: degreasing → washing → rust → cleaning → conditioning → phosphating → washing → saponification → washing → drying → oiled → Inventory 5. Preparation and Maintenance: preparation 1000L 5.1 bath add 1/2 volume of water to the tank. 5.2 added 200kg blackening table transfers to tank. 5.3 add water to the mark, stir, confirm acidity. 6. Adjustment and maintenance methods: 6.1 after a period of time will reduce the free acidity of the bath can be supplemented with this table swap, each additional 6.7kg free acidity could increase to about a "point." 6.2 table swap acidic and should be used in strict accordance with the specified time for processing, Where it is not allowed table-adjusted parts collide, touch or wash with water. 6.3 Where with copper, aluminum, zinc and other metals steel assembly, not allowed to enter this table transfer slots. 6.4 bath after a period of time can be continuously added over 34 times, and then turn the tank handle, remove part of the old solution, in proportion to additional blackening table swap. 7. Packaging storage 25kg plastic drum, stored in a cool ventilated place, shelf life of six months.
