Performance Technical Index:
TA: 20-25 FA: 0.5-0.7 Density: 1.02Ī0.02 PH: 3.0-3.5
Appearance: Colorless, black Using temperature: 0-30 centigrade
Blackening Area: 5-10m2/kg Color of flim: Black Blackening time: 3-5min.
Weight of the film: 0.5-1.5g/m2 Thickness of the film: 2um
20g/L saline soak: 1.5h min Copper sulfate solution guttate: 1min
25 centigrade hanging piece: No rust occurr within 12 months
Mix the AIR-T7A and AIR-T7B in the proportion of 1:1, and immerge the parts, which after the processes of degreasing-water-washing-acid pickling-water-washing, into the blackening tank for 3-5 min., then the black film can be formed.
In consecutive utilization, if the formation of blackening film exceeds ten min., then itís necessary to remix the blackening solution again. If the degreasing process is not complete, blackening film wonít be firm, and tends to counter yellow and rusting. If the oxide scale canít be cleaned completely, then blackening film and substract wonít be connected tightly and tends to blister and exfoliated. The blackened parts should be dried as soon as possible and dip coating antirust oil as well.
