TYPE of CLEANER (Liquid VS Powder Cleaner)

Cleaners :

- Solid Product (Powder)

- Liquid Product (Water based)

LIQUID VS POWDER CLEANER 

a.   Liquid products

    •    Advantages :

       - Easy to handle

       - No mixing vessel necessary

       - Automatical dosing out of delivery package possible (conductivity, constant amount per body)

       -  No formation of dust

       -  Multi-way-package/tanker 

    •    Disadvantages :

          -  Contains water as a solvent

          -  Higher cost for raw material, so the price of liquid cleaner more expensive than powder cleaner

         Liquid cleaner are :  
         - Acid Cleaner (for pickling and rust remover) : Diaclean AC-200, Diaclean AC-300, Diaclean              AC-500, Diaclean AC-600
         - Neutral Cleaner : Diaclean NC-330, Diaclean NC-333, Diaclean NC-310
         - Alkaline cleaner : Diaclean M-160 L, Diaclean M-220L

       b.   Powder products

     •  Advantages :

      - 100 % active material, no solvent

      -  Lower costs for raw materials

     •   Disadvantages :

          - Mixing vessel necessary

          - Formation of dust
          - High package effort

         Powder Cleaner usually as Alkaline Cleaner
        

Diaclean H-280, packaging :25Kg/Bag

ZINC PHOSPHATING (Spray Application)

Zinc phosphate (Zn₃(PO₄)₂) is an inorganic chemical compound used as a corrosion resistant coating on metal surfaces.

Phosphate salts is applied via spraying or immersion and chemically reacts with the surface of the part being coated to form a layer of insoluble, crystalline phosphates. Normal operation pH : 2.6 - 3.0

The operation should be controlled, to make best result :

- Temperature (if use Hot Temperature)

- Time

- pH

- Product concentration

- Free and Total Acid

  --Total acid is measure of total bath concentration/ Zn Content
  --Free Acid is maintain Zn solubility

The other chemicals should be add  in Zinc Phosphating are :
- Accelerator  (Dia Toner 20)
- Neutralizer (Dia Starter 40 - maintain pH, Free acid)

Advantage :

- Coating thickness 2.000 - 10.000 nm (usually 1.5 -  2.5 g/m2)

- High corrosion protection

Quality requirements on phosphate coating prior to painting :

- Uniform, small crystal

I. Zinc Phosphate, 3 kation (Spray application):

Our Product : Diafos 1000 Prep (Make Up), Diafos 1000 Alim (Replenishing)

Packaging : DF 1000 Prep (25 Kg/can), DF 1000 Alim (28 Kg/can)

DIAFOS 1000 is a nitrite accelerated tricationic phosphating process for steel, galvanized and alloy coated (Zn/Ni) steel. It generates a fine crystalline coating of manganese containing zinc phosphate. The crystalline layer has very good rust protecting properties and is an excellent support for subsequent painting or organic coating. DIAFOS 1000 gives particularly good results for steel in combination with galvanized or hot dip galvanized steel.
