Product Operating Procedure

Completely degreased, derusted components should be dipped or immersed in Teja phos 101-M solution and keep the temperature at 92 – 98°C for 15 minutes till gassing stops. Excessive etching of the metal surface is likely to take place, which is caused by excessive free acid and which should be controlled.

The most important factor before Teja phos 101-M operation is that the components should be cleaned well, which will affect the grain size of the Tejaphos-101M manganese phosphating coating. It should be absolutely free from oils, soils and rust.

Product Application Equipment's

Teja phos 101-M tank should be fabricated with 4 to 5 mm thick M. S. (preferably SS 316) plates with continuous convection current heating system.

Iron Contents

Pipette out 10 ml of the bath solution sample of (Teja phos 101-M) into 150 ml beaker, add 2 ml of 50% H2SO4. 
Then titrate it with N/10 KmnO4 solution to a permanent pink colour. The ml of KmnO4 solution will indicate the percentage of the Iron in the bath. The normal range is 0.15 to 0.23% Iron.

Generally, Iron contents increase gradually in the running bath and it has to be reduced    to a required range. In order to obtain a good and smooth coatings. To reduce the iron contents by 0.5% add 50 gm. Of 35% H2O2 (Hydrogen Peroxide) per 100 liters of solution.

When Iron Content Increases

Add required amount of 35% H2O2 Dilute with water prior to addition to the bath.
Let it react for 15 minutes.
Add required amounts of neutralizer in a slurry form.
Let it react for 15 minutes.
Again check up the iron content and repeat the procedure. The very important thing is to maintain the temperature between 92 to 98oC. Prior to, commencing any production. Let the sludge settle at the bottom to follow this method. Discard the bath when Iron concentration reaches beyond 7 to 8%.

Chemical Replenishment

Since there is a continuous sludge generation in phosphating bath due to phosphating of ferrous metal surface the bath should desludged periodically and chemical concentration should be replenished by adding chemical to achieve specified bath pointage.

Safety Measures

Teja phos 101-M is an acidic liquid material, and while handling proper care should be taken, protect eye, skin by means of goggles, aprons, gloves and face shield  etc. When it comes in contact with skin and eyes wash thoroughly with flush off water and get medical advice.For further Information please refer our Material Handling and Personal safety Data Sheet No.2.

Product Operating Procedure

Pickling

Pickling should be carried out either in sulphuric or Hydrochloric Acid, in combination with suitable acid Inhibitors in sufficient strength to remove rust and scale present on the work.

Rinsing

The stage rinsing should be followed after the pickling process, first rinse with cold water and finally rinse with jet pressure. The rinsing tank should be cleaned regularly.

Phosphating

Fill the tank 2/3 with clean water and add recommended amounts of Tejaphos-202. Fill the tank to the operating level with water and mix thoroughly and for total acid and if necessary add enough Tejaphos-202 to bring total acid to operating level and mix thoroughly. Add 30-35 gm of Tejaactivator NP accelerator in the bath by dissolved in cold water. After phosphating with Tejaphos-202, the work should be rinsed with continuous flowing water and subsequently once again rinsed in hot neutralizing solution. The neutralizing solution is made up with 0.1 kg of soda ash per 100 litres of bath.

Operating Recommendation

Proper rinsing is very much essential after pickling in mineral acids, in order to remove the acid residues from the surface of the work. Any carry over of the acid to the phosphating tank will lead to excessive sludge formation leading to deterioration of phosphate coating and high chemical cost.

Proper control of temperature, pointage and time to minimise the chemical consumption.
Thin  coating may result from a low bath temperature of insufficient treating  time.

Product Application Equipment
