Be suitable for degreasing aluminum aluminum alloymagnesiummagnesium alloy work pieces in dipping and spray.

Brief: JH-1356 consist of weak acid, low foam surface active agent and zwitterion to avoid corrosion and acid fog.

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: 40-80kg/1000l

                  Outlook: colorless to yellowish

                  Free acid: 20-40

                  Specific gravity: 1.08-1.18

                  Temperature: rt-40degree

                  Dipping time: 5-10minutes

                  Spray time: 90-120s

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 add6kg/1000l if free acid increase 1 point.

                       Could be drained in regular time

Reserve requirement:

Reserve in dry shady and cool place to avoid sunshine.

Packing:25kg/barrel.

Effluent disposal: Should observe chemical products disposal rules.

bath solution is acid which should be neutralized or disposed before drain.
