Feature
Can remove the oil, grease, metal filling and dust
The consumption is 60~80% of similar liquid degreaser
Effective component is 1.2~1.5 times of liquid degreaser
Scarcely any impure ion and very weak corrosion on the equipment
Apply to the degrease and cleaning of metal chemical conversion treatment
Steel plate cleaning effect: (1) residual oil value <10mg/m2; (2) residual iron value <15mg/m2; (3) reflectivity >90%; (4) Rust inhibition preserve period (before annealing) >7 days.
Application process
Appearance: Solid
pH: 12~14
Treatment Temperature: 60~85℃
Free alkalinity: 12-30 pt
Solution concentration: 2.0~4.0%
Free alkalinity test method: Firstly, add 10ml aqueous into an Erlenmeyer flask. Then add 0.1~0.5ml phenolphthalein indicator. Using 0.1mol/L HCl standard solution to titrate it. While the solution changes from red to colorless. The consumption volume of 0.1mol/L HCl standard solution is the free alkalinity value.
Application
-Cast iron, hot rolled steel, cold rolled steel and aluminum alloy
-Other iron and steel products
Note
MC-DE5412B is strong alkali and wear the protective equipment while using it.
The solution tank and the pump must be steel (304L or 316L)
After the products are processed, don’t make the products encounter the water
