Be suitable for degreasing zinc stearate remained on aluminium work pieces’ surface.
Brief : JH1355 consist of organic acid, non-ion surface active agent and zwitterion free from phosphor and nitrogen.
Bath solution compound: Put cold water into the tank till three-quarter with appropriate degreasing agent, then stirring, after, add sufficient water till working level, after, heat bath solution till operating temperature.
Control parameter: compound concentration: 40-60kg/1000l
Outlook: yellow
Free acid: 80-120
Specific gravity: 1.0-1.1
Temperature: 50-70degree
Dipping time: 5-10minutes(dipping)
2-5minutes(ultrasonic)
Test method: free acid:1.pipet 10ml sample to conical beaker,
2. drip 3-4driping bromphenol indicator,
3. drip 0.1n NAOH into the solution, stop when yellow change to blue.
4. the consumption of NAOH is the free acid.
Density: test sample with gravimeter in 25 degree
Bath solution control: need to add2kg/1000l if free acid increase 0.5point.
We could drain the bath solution regularly in continuous flow or automatic flow to maintain the TFR lower than MAX TFR.
Reserve requirement:
Reserve in dry shady and cool place to avoid sunshine.
Packing:25kg/barrel,200kg/barrel
Effluent disposal: Should observe chemical products disposal rules.
bath solution is acid which should be neutralized or disposed before drain.
