Embodiment 1
[0046] Embodiment 1 A kind of bolt surface blackening treatment liquid
[0047] Contains the following components:
[0048] A component:
[0049]
[0050] B component:
[0051]
[0052] The bolt surface blackening treatment process includes the following steps:
[0053] The bolts are cleaned, degreased, washed with water once, derusted, cleaned twice, phosphating / blackened, washed three times, and dried, and the bolts after the blackened treatment are dehydrated and rust-proofed, and the blackened film on the surface is completely dried That is, the blackening process is completed.
[0054] Described degreasing, derusting steps are routine operations in this field;
[0055] Phosphating / blackening treatment: transfer the bolts after secondary cleaning into the blackening tank, now add component A to the blackening tank for phosphating, then add component B for blackening treatment, monitor pH The value is 2.5-3.5, the temperature is 30°C, and the blackening treatment...
