Weld Scale Remover - High Purity Acidic Blend For Effective Oxide Film Removal, Corrosion Resistance, Adaptable For Various Industrial Applications

We have wide experience in coating chemicals and this make
us one of the preferred manufacturers and exporters of Weld Scale Remover. After welding, the joints of stainless
steels produce a heavy tightly adherent oxide film that is commonly known as welding
scale. To remove that scale, our offered
Weld Scale Removeris used in
industries. This chemical also forms a passive layer on the metal surface thereby
reducing the level of corrosion. High in purity and longer in shelf life, all
these chemicals are available in different air tight packaging.

Product Operating Data

Product Operating Procedure
Kemklin-106 is simply diluted in 1:3 parts with water. Prior to immersion in Kemklin-106 bath, excess oil, grease and loose rust should be removed manually or by alkaline degreasing in Trichlor ethylene degreasing. The dipping time period required for cleaning depends upon the amount of contamination, concentration, temperature and ferrous iron contents built up in the bath.

After the immersion in Kemklin-106 bath, the work should be rinsed thoroughly in clean running water and subjected to phosphating process.

Kemklin-106 bath can be maintained by simple titration and does not require any skill labour or chemical knowledge. Bath should be maintained at operating level with recommended concentration freshly prepared bath acts rapidly but the action gradually degreases due to the accumulation of ferrous iron concentration in the bath. Increase the temperature at this stage accelerates the derusting action, but the temperature should be controlled as specified. The ferrous ion in the bath should be not exceed 7%.

Product Application Equipment
Kemklin-106 tanks should be lead lined, rubber lined, glass fibre, rigid polythene, stainless steel tanks made out of 18 guage sheets preferred. Steam coil or electric heaters.

Testing and Control Procedure
Pipette out 10 ml. Of bath solution and further dilute it to 100 ml. With distilled water. Pipette out 10 ml. Diluted solution into the conical flask and add 5 -6 drops of methyl orange indicator. Titrate it N/10 sodium hydroxide solution till yellow end point is observed. The volume of N/10 sodium hydroxide use is the bath pointage.

Iron Concentration
Pipette out 10 ml. bath solution in conical flask and add 10ml. of 50% concentration H2SO4. Mix it thoroughly add titrate this against N/10. Kmno4 solution till the colour change to light pink stable for 15 seconds. % of Iron in the bath is calculated as 0.056 x Titre reading maximum permissible limit of iron concentration in Kemklin-106 bath is 7%.

Chemical Replenishment
The bath should be discarded when the concentrated solution and increase in the temperature do not show faster derusting action and powder deposits appear on the surface of the metal. Add 1.1 ltr in the bath for increasing pointage by one unit.

Safety Measures
Kemklin-106 is an acidic liquid material, and while handling it proper care should be taken. Protect eyes and skin by means of goggles, gloves, etc. If it comes in contact with skin and eyes thoroughly flush it off with water and get medical advice.

General Information
Rust removal: Excellent.
