Chengdu Branch-brand LH-60-type steel General Drawing phosphate solution

1. Application: The phosphating agent for a variety of high, drawing, fine bar and other processes, carbon steel, alloy tube, also applies to the short shelf life of the process sometimes rust phosphating parts. Its phosphate film structure has good lubricating properties and drawing performance, low unit cost, processing time savings of more than half of the other advantages. 2. Main features: 2.1 Good stability, less sediment, after not contain sodium nitrite (NaNO2), sodium fluoride (NaF) and other harmful substances, used for a period of time just add this bonderite adjust to. 2.2 process is simple, easy to manage, using one-component addenda. 2.3 phosphate coating is gray dense, continuous, uniform and no ash hanging crystals, can improve the quality of life of the mold drawing and parts. 2.4 easy to use, the optimum temperature lubricant poured into water, and natural dissolution can be used. 3. Technical Specifications: Item Index Appearance light blue, green liquid dosage (%) 3-6 total acidity (point) 8 to 20 free acidity (point) 0.5-3 treatment temperature (℃) 80 treatment time (min) 2 ~ 10 4. Phosphate way dipping process: degreasing → washing → acid → washing → phosphate → washing → drying or drying saponification → → post-processing 5. Processing: 5.1 phosphate should be washed with water, and then immersed in lubricant saponification , usually 1 ~ 5min. 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 before adding 1/2 volume of the water tank, then add 50kgLH-60-type drawing phosphating agent, add a little water to wash the residue was poured into the tank empty barrels, and finally to the mark with water, stir, determination of total acidity and free acidity, can be put into if within the process. 7. Packing and storage: 25kg, 30kg, 60kg plastic drum, stored in a cool ventilated place, shelf life of one year.
