Temperature 75 - 85°C

Product Operating Procedure

Fill the tank with TejaDegreaser-HD with 2/3 of desired quanity of water and heat it about 75-85°C. Add 5 kgs. Of TejaDegreaser-HD powder per 100 ltrs. bath with continuous agitation till the chemicals are completely dissolved. Fill the tank to the operating level and raise the temperature to 85°C.   Stir the bath and draw the sample for the determination of pointage. 

Strength of TejaDegreaser-HD bath can be increased if the components are heavily contaminated with heavy oil or grease. Maintenance of the temperature is a very important factor. If the temperature of the bath is low, the efficiency of the degreasing chemical will be affected even if the concentration and the treatment time are increased. The components should be thoroughly rinsed with over flowing water system until unless Teja Degreaser-HD      is completely removed till the PH of Water becomes Neutral.

Product Application Equipment.

Teja Degreaser-HD tank should be fabricated with 4 to 5 mm thick M. S. plates (Preferably  SS 316 tank) with continuous agitation arrangement by convection current from a heating unit.

Testing and Control Procedure

Pipette out 10 ml. of the bath solution into a conical flask. Add 90 ml. of distilled water and    add 2 to 3 drops of indicator methyl orange indicator. Titrate against N/10 sulfuric acid till the colour changes from yellow to red. The burette reading is the pointage.  The pointage of   the degreasing should always be maintained at the recommended level

Chemical Replenishment

The efficiency of the degreasing bath falls due to the carry over of oils coming from the work is emulsified in the bath solution and presence of the sludge at the bottom. At this stage, Teja Degreaser-HD bath should be discarded and sent to ETP.

Safety Measures

Teja Degreaser-HD contact with skin, eyes, and clothing should be avoided and proper safety  precautions should be taken by the operators by using gloves, goggles, face shield and safety clothing. In case of accident, the affected portions should be continuously flushed with water and a   physician should be immediately consulted.

Product description

Tejalube 2000 is a drawing lubricant with very high film strength and is used on cold extrusion and cold operation. It is applied by dip process on the metallic surface which has been properly bonderized. It reacts with Tejalube 2000 coating, forming a lubricant layer, which helps in cold forming of metal and retards the formation of rust.

Product Operating Data

Concentration 3 - 5%
Dip Time 2 – 3 minutes
Temperature 60 - 80°c
Pointage: TAFa -1 ml (min)

Product Operating Procedure

Concentration of Tejalube 2000 solution may range from 3 -15% depending upon the end operation. Extrusion operation generally requires more concentration than tube-drawing, wire drawing or deep drawing but the optimum concentration is best determined experimentally.

Before using the lubricant determine the free acidity according to method given below. If this is outside th range adjust it by adding required amount of caustic soda or sulphuric acid.

The treatment consists of dipping the job which have been bonderized and properly rinsed in Tejalube 2000 at 60-80° C 4 – 5 mts to permit the lubricant to penetrate and react with coating. The temperature at which Tejalube 2000 is operating should not be allowed to vary more than ±20°C. The temperature is established for each project and generally is in the range of 60 – 70°c. It drainage is a problem because of the shape of components the upper range is advisable.

Product Application Equipment

Tejalube 2000 tank should be fabricated with 3 to 4 mm thick M.S. Plates with continuous current heating system.

Testing and Control Procedure

Sample taken from the hot lubricatly bath may be analyzed immediately. If it is allowed to cool it will become thick and must be repeated for analysis.

Free Acidity

Take 100 ml of Tejalube 2000 from bath. Transfer 10 ml to conical flask. Add 200 ml of (ISOPROPANOL with 2 – 3 drop of phenolphthalein ). Heat to boiling when still hot titrate against N/10 sodium Hydroxide to a permanent pink colour N/10 NaoH used will give free acidity. It should be 0 – 1.00 mls.

Chemical Replenishment

If free acidity is more than 1.00. Add 200 gms of caustic soda (Dissolved in water) in 1000 litres of solution. This will lower the F.A. By 0.5 m.

Safety Measures

Tejalube 2000 is a highly alkaline material. Direct contact can cause burns to eyes and skin, therefore use adequate ventilation. Avoid breathing vapour or mist, do not take internally.

In case of contact, immediately wash eyes or skin with plenty of water for at lease 15 minutes. Get medical attention remove contaminated clothing and shoes, wash them before re-use. If swallowed, wash out mouth with water. Give several gears of water to drink followed by milk of magnesia. Incas of severe exposure get medical attention.
