Various phosphating chemicals offered by us are mentioned details:

Meprophos 2614 Z:

• It is used to produce crystalline zinc phosphate coating obtained as per class A of IS 3618
• It is widely used in seven-tank process.

Step One (Degreasing):

If the items to be phosphated have oily layer of grease then its degreasing should be done prior to any process

Various types of degreasing include following Alkaline Degreasing:

Following are the steps for alkaline degreasing:

• Dissolve Meproche 245 at a ratio of 5% in water
• Heat upto 80-85°C and dip the parts for 5 to 10 minutes
• It removes industrial soil age, oil and grease and provides dirt free parts

Test & Replenishment:

• Take 10 ml of bath material and titrate against 0.1 N Sulfuric acid, using phenolphthalein as indicator
• The pink end point should be between 60-65 ml and if found less add more Meproche 245 @ 0.8 kg per 1000 liters of bath material
• It gives rise in pointage (No. of ml of 0.1 N sulfuric acid) and thus maintain the pointage between 60 and 65
• Remove the oil and grease from the top of the bath by skimming, as and when generated

Solution Degreasing:

• Use of Trichloro Ethylene or 1: 1: 1 Trichloro Ethane or Meproche Chlorosol
• Ultrasonic Vibration is used if the parts are small then to accelerate the degreasing greatly
• Meproche Chlorosol is very effective and cheaper than Tricholoro ethylene and 1:1:1 Trichloro Ethane.

Specifications:

• Dip time = 10 to 15 seconds
• Temperature = RT (or 5 to 10 minutes for DIP type degreasing at room temperature or 5 to 20 minutes at 85° c for vapor degreasing

Step Two (Rinsing):

Rinse the components in hot/cold running water

Step Three (Pickling):

• Following are the steps to be followed in the pickling stage
• Acid pickling bath should contain 14 to 18% concentration of Hydrochloric acid 18% Conc. from April to September
• Add l litres of Meprolene per 1000 kgs of the bath material
