Phosphating solution for steel wire pulling
detail
This product is zinc series drawing phosphating solution. After treatment, a uniform and dense phosphate crystal film can be formed on the surface of steel. The film plays the role of lubrication and reducing friction during wire drawing. The product has the advantages of simple operation and technology. It has the advantages of large capacity and less sediment.

2、 Main features
1. The operation is simple and the management is convenient.
2. This product has good stability, less sediment and long service life.
3. The phosphating film has dense crystal, gray black and no ash. It can enhance the lubricity of wire rod and has low comprehensive cost.
3、 Application method and process parameters
1. Treatment process: rust removal → neutralization → water washing → phosphating → water washing → wetting agent
2. Prepare the product into 10-20% working solution, add appropriate amount of accelerator per ton, and stir evenly.
3. Process parameters:
Acid ratio: 5 ～ 7, treatment temperature: 75 ～ 90 ℃
TA: 40 ～ 55pt, treatment time: 3 ～ 10min
4. As the concentration changes continuously in the continuous treatment process, it is necessary to measure the concentration of each index regularly to keep each index within the specified process concentration range.
4、 Packaging, storage and transportation
30kg plastic barrel packaging, storage and transportation temperature not less than 0 ℃.
