Metal degreaser cleaner MC-DE5100B

Feature

Contain biodegradable surfactant

Can remove the oil, grease, metal filling and dust

Scarcely any impure ion and very weak corrosion on the equipment

Apply to the degrease and cleaning of metal chemical conversion treatment

Application process

• Appearance: Liquid
• pH: 12~14
• Treatment Temperature: 60~80℃
• Free alkalinity: 12-30 pt
• Solution concentration: 2.5~6.0%

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.

Total alkalinity test method: Firstly, add 10ml aqueous into an Erlenmeyer flask. Then add 0.1~0.5ml bromophenol blue indicator. Using 0.1mol/L HCl standard solution to titrate it. While the solution changes from blue to bright yellow. The consumption volume of 0.1mol/L HCl standard solution is the total alkalinity value.

Note:

1. Add 0.19kg MC-DE5100B into 1000L water and the free alkalinity increases by 1.0 pt.

2. Please replace the solution while (total alkalinity value/free alkalinity value)>2.

Application

-Cast iron, hot rolled steel, cold rolled steel and aluminum alloy

-Other iron and steel products

Note

MC-DE5100B is strong alkali liquid 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
