Feature

Non corrosion effect on the metal surface

One-time processing complete to degrease and remove rust

No acid mist, no pollution, low foaming and acid liquid products

Can effectively remove cold rolled steel, cast iron and precision parts surface grease, rust, dust and dirt. 

Application process

Appearance: Colorless or yellowish liquid

Applied temperature: Normal temperature~70℃

MC-DE6810B applied concentration: 100%

Treatment time: 5~20min

pH: ≤1.5

Treatment way: Dip or spray

Add the MC-DE6810B 1000L into a tank. Then using treat the metal by dipping or spraying. Please remove rust, dust oil and other pollution by overflow or other way in time. It need to supplement the MC-DE6810B, when the effect can not meet your request.

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

Total acidity test method: Firstly, add 10ml aqueous into an Erlenmeyer flask. Then add 0.1~0.5ml phenolphthalein indicator. Using 0.1mol/L NaOH standard solution to titrate it. While the solution changes from colorless to light red. The consumption volume of 0.1mol/L NaOH standard solution is the total acidity value.

Application

-Cold rolled steel, cast iron

-Metal precision part etc.

Note

Please wear the protective gloves when using it.

MC-DE6810B is acid liquid and wear the protective equipment while using it.

It contains the phosphate and please treat the waste liquid before discharge.

Wash immediately with water when skin encounter the cleaning agent.
