Product code: MC-01

Origin: NBT Chemical

MC – 01 degreasing chemical is a mixture of acid and surfactant and aluminum corrosion inhibitor, used specifically for aluminum chromate process, pre-treatment of powder coating.

• Solution, soluble in water, mildly acidic
• Compatible with non-ferrous metals such as aluminum, copper, zinc, iron and alloys.
• High surface additive properties, suspends and dissolves grease. Fast working time, high economic efficiency, wide working range, high chemical life.
• Does not cause aluminum to become moldy or black.

Physical and chemical properties:
– Appearance: solution, light yellow
– Solubility, (water, 250C, g/l): completely soluble
– Specific gravity, (250C, g/ml): 1.12 ± 0.05
– pH, (5%, w/v): mild acid
Bartending:
Add water to 1/3 of the tank volume, then slowly dissolve (stir) MC-04 chemical according to the ratio below, fill with water to the specified line.
New phase:
– Mixing ratio MC – 04, (g/l): 50 (30 ÷ 80)
– Temperature, (0C): normal
Tank material, Composite (FRP), PVC, PP, stainless steel 316.

Working standards
– TA (ml): 25 (18 ÷ 50)
– Time, (minutes): 5 (3 ÷ 30)
– pH, (250C): mild acid
– Temperature, (0C): normal
– Light aeration.
– Color clear to light yellow.

Check, analyze and supplement.
– Color: uniform, clear to light yellow, no oil film.
– Check the acid point Kt:
Prepare 5% sample solution (v/v): Take 50 ml of sample solution into a 1 liter volumetric flask, add distilled water to the mark.
Take 10 ml of 5% sample solution into a 250 ml conical flask, add 100 ml of distilled water.
Add 3 ÷ 5 drops of PP color indicator.
Titrate with 0.1N NaOH solution until the solution changes from colorless to pink, then stop.
The number of ml of 0.1N NaOH solution used is the number of acid points Kt.
– Supplement : add chemical MC – 04 according to the formula: M(MC – 04) = 2.5 x (K0 – Kt) x Vlv
In which: K0 is the required point for example (K0 = 30), Vlv is the Working Volume, (m3)
– Additional notes:
Check (times/day): 1 ÷ 2
Change tank (day/time): 5 ÷ 10
Change tank (month/time): 1 ÷ 6
Skim the oil regularly.
However, depending on the actual product, appropriate supplementary and replacement options should be proposed.

Notes when using MC-01 oil removing chemical:
MC-04 degreasing chemical is acidic, when using it, you must comply with labor safety, wear protective clothing, rubber gloves, glasses, gas mask, and work in a well-ventilated area.

Handling of accidents:
