Embodiment 1
[0014] Based on the total weight of the antirust agent as 100%, according to the following proportions: 1.5% sodium molybdate, 4% sodium silicate, 0.5% hexamethylenetetramine, 0.05% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:5 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 3 minutes and then take it out. The workpiece has not been rusted after being stored on site for 6 months.
Embodiment 2
[0016] Based on the total weight of the antirust agent as 100%, according to the following proportions: 0.5% sodium molybdate, 2% sodium silicate, 3% hexamethylenetetramine, 0.3% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:8 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 15 minutes and take it out. The workpiece has not been rusted after being stored on site for 6 months.
Embodiment 3
[0018] Based on the total weight of the antirust agent as 100%, according to the following proportions: 1.0% sodium molybdate, 0.2% sodium silicate, 1.5% hexamethylenetetramine, 0.5% non-ionic surface active agent, prepare 100kg antirust agent Rust agent. The prepared antirust agent is mixed with water at a ratio of 1:10 to make an antirust solution. After phosphating and washing the workpiece, immerse it in the antirust solution for 30 minutes and then take it out. The workpiece has not been rusted after being stored on site for 6 months.
