During work: above-mentioned Phosphating Solution stoste and water are mixed with working fluid with the proportioning of 1:15,
First in Phosphating Slot, Phosphating Slot useful volume 60% is filled to, the present embodiment Phosphating Solution taking requirement is poured in Phosphating Slot fully to stir and is made into working fluid, and adjustment working fluid processing range is to total acidity: 25-35 point, free acidity: 0.8-1.2 point, pH:3-4, use temperature 80-95 DEG C.
Be that the cold-reduced sheet of 120*3*4 drops in Phosphating Slot and soaks 6 minutes by specification, pull out immediately and define one deck phosphatize phosphate coat on surface, as follows to its service check:
Phosphatize phosphate coat outward appearance: perform by GB2828-88, meet the requirements.
Phosphorization film quality: measuring by GB6807-97, is 1.90-2.20g/m
2, reach phosphatization requirement completely.
Phosphatize phosphate coat solidity to corrosion: measure by GB6807-91 Appendix D, spot corrosion 3 minutes.
Shock-resistance: spray polyurethane paint by the steel plate with the process of this Phosphating Solution.Shock-resistance 550Ncm is measured by GB1732.
Snappiness: measure snappiness by GB1731 and pass through A=1mm.
Adhesion test: measure adhesion 1 grade by GB1720, and during non-phosphatization, sticking power is 2-3 level, illustrates that this phosphatize phosphate coat and paint film have good matching capacity.
