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.
