Yellowish Outlook Metal Cleaning Agent for aluminium alloy degreasing

Be used for degreasing for various aluminium &alluminium alloymagnesium& magnesium alloy in dipping and spray.

Brief:  JH1350 is consist of weak acids with corrosion inhibition without phosphor and acid fog, thus, we could improve our efficiency and save cost with good performance. Be used for degreasing for various aluminium &alluminium alloymagnesium& magnesium alloy in dipping and spray.

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: 30-50kg/1000l

                  Outlook: yellowish

                  Free acid: 30-50

                  Specific gravity: 1.15-1.25

                  Temperature: rt-40degree

                  Dipping time: 5-15minutes

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 add1.3kg/1000l if free acid increase 1 point.

   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.
