Colorless to light yellow transparent liquid. It has a certain
irritating, and water soluble.
Be used for degreasing for various aluminium &alluminium
alloymagnesium& magnesium alloy in dipping and spray.
Brief: JH1351 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.If it is not used in the process of casting
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: Colorless to yellowish liquid
Free acid: 30-50
Specific gravity: 1.1-1.2
Dipping time: 2-10minutes
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
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 in dry shady and cool place to avoid sunshine
Effluent disposal: Should observe chemical products disposal rules.
bath solution is acid which should be neutralized or disposed
