Metal Pretreatment Chemicals Application
Metal Pretreatment Chemicals is suitable for degreasing for alluminium&alluminium alloymagnesium& magnesium alloy in dipping and spray.
Metal Pretreatment Chemicals Introduction
Metal Pretreatment Chemicals consist of week acid, load form surface active agent and zwitterion to avoid corrosion and acid fog, specially suitable for alluminium products degreasing. Be suitable for degreasing for alluminium&alluminium alloymagnesium& magnesium alloy in dipping and spray. If it is not used in the process of casting aluminum
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.
Metal Pretreatment Chemicals Details
Control parameter: compound concentration: 40-60kg/1000l
Outlook: colorless to yellowish liquid
Free acid: 30-50
Specific gravity: 1.1-1.2
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 add1kg/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.
