Product Operating Procedure

The articles to be processed in the Teja phos -300 solution should be free from oils, greases, dirts, rust and scales etc.

Derusting

Remove rust and scales present on the articles to be processed by immersion in Teja Derusting chemical. If scales are heavy the article should be immersed in Teja Deruster- MA. After pickling rinsing should be carried out thoroughly. If possible in two stages.

Phosphating

Immerse the components in Teja phos -300 bath for 5 to 40 minutes at 60-70 dg.             
temperature. Immersion time depends on the type of coating weight required. Medium weight coating can be produced by immersion for 5 – 10 minutes which serves a good base for under gloss pains heavier coatings with Teja phos -300 can be obtained by Immersion for 20 -40 minutes which increase corrosion resistance. Rinse the phosphated articles in cold running water followed by hot water rinse to accelerate drying.

Passivation

Articles should be passivated by immersion in Hot Tejapassivation solution at 70°C for 30 seconds to 1 minute.

Drying

After passivation the articles should be dried immediately. Drying can be done inside a hot air circulating oven or by means of compressed air.

Fill the tank 2/3 with water and add 2.5 to 5 liters of Teja phos -300 per 100 litres. Fill the bath upto its operating level and stir the solution thoroughly. Heat the bath to 70°C and add few kgs. Of degreased iron scrap or steel wool. After 15-20 minutes when the gassing has been ceased, remove the metal and check iron percentage. Ferrous Iron concentration should be 0.05% minimum. Otherwise repeat the operation.

Adjust the pointage of bath to working condition by adding (Teja phos -300). Heat the bath to the operating temperature Teja phos -300 bath can be easily controlled within the operating temperature. Teja phos -300 bath can be easily controlled within the operating limits by simple titration and maintained by periodic additions of Teja phos -300.

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.

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.
