HYDROCHLORIC ACID PICKLING INHIBITOR

INTIAL BATH MAKE UP:

Add 3 – 5 Litre Inhibitor Solution for 1000 litre Bath volume

OPERATING PARAMETERS:

• Concentration: 3 – 5 Litre / per 1000 Litre
• Temperature: 60oC-80oC
• Acid Concentration : 12% -18% (W/V)

BATH MAINTENANCE:

This inhibitor is a reaction product of suitable formulation, which has no actual Analysis method to determine the concentration. However, after every interval, one may check the inhibitor efficiency.

INHIBITOR EFFICIENCY DETERMINATION METHOD:

• Weight accurately a cleaned metal sheet ( W 1 gm)
• Dip the metal sheet to the acid bath without using inhibitor. Concentration of acid bath and temperature, contact time should be same as the pickling bath.
• Lift the metal sheet after the contact time is over, rinse and dry quickly to avoid Rust formation. Weigh Accurately ( W2)
• Weigh accurately another similar type cleaned metal sheet (W3)
• Dip the metal sheet (W3) in the pickling bath containing INHIBITOR, Maintaining same concentration, temperature and time of contact.
• Lift the metal sheet, rinse and dry quickly, weigh accurately (W4)

CALCULATION:

Metal Loss in % = (W1-W2) x 100% = A &(W3-W4) x 100% = B W1 W3

INHIBITOR EFFICIENCY = (A – B) x 100% A

DISPOSAL

This inhibitor is non hazardous in nature and is bio-degradable. The acid used in the pickling line should be neutralized with lime and discharged maintaining Local regulation. Our Product is compliant with ARP’s.

SAFETY

Wear safely goggles, hand gloves, during handling inhibitor. Splashes on the skin should be washed –off with plenty of water.

SHELF LIFE:

Minimum 6 months from the month of manufacturing.

PACKAGING:

50/200 Litre HDPE Container

USE OF INHIBITORS IN PICKLING BATH HAS FOLLOWING BENEFITS:

• Metal Savings (0.1-1.0%)
• Brighter Metal Surface
• Smooth Surface Finish
• Less Quantity of Effluent.
• Increases Pickling Bath Line Efficiency (Less Acid Consumption)
• Cut Down of HCL Fumes
• Metal Surface without pitting
