Rinse Tank Additive for Cold Rolling Mills: Rust Control and High Gloss Finish
A rinse tank additive, effectively acting as a rinse tank additive for metal finishing, is a specialized chemical agent dosed into the rinse water of cold rolling mills immediately after the pickling stage. It neutralizes residual acid carryover, prevents the rapid formation of flash rust, and imparts a high gloss finish to the freshly pickled steel strip before further processing.
What is SURINSE by Sudha Speciality Chemicals?
SURINSE is a highly alkaline, biodegradable liquid antacid formulation designed specifically for continuous rinse tanks. As a premium rinse water treatment chemical, it acts rapidly to combat hydrochloric or sulfuric acid carryover from pickling lines, ensuring the rinse water quality remains high while protecting the structural integrity and visual appearance of the cold rolled coil.
What are the Benefits of Using Rinse Tank Additives?
Adding a highly compatible treatment chemical like SURINSE to your rinse water system delivers immediate operational and quality improvements for cold rolling mills.
- ● Neutralizes Acid Carryover: Instantly balances pH drops caused by acid dragged into the rinse tank from the pickling line.
- ● Stops Flash Rust: Creates a protective barrier that retards rust formation on the exposed coil surface during transit or staging, making it a highly reliable anti-stain rinse tank additive.
- ● Imparts High Gloss: Functioning as a top-tier metal surface rinsing chemical, it leaves a bright, shining finish on the freshly cleaned steel strip.
- ● Enhances Paint Adhesion: Much like a specialized post-plating rinse additive, it produces an exceptionally smooth surface that significantly improves the bonding strength of subsequent color coating chemicals.
- ● Eco-Friendly Profile: The formulation is completely biodegradable and highly compatible with existing water treatment protocols.
Technical Specifications and Application Dosages of Rinse Tank Additives
Plant engineers should maintain the following physical parameters and dosing guidelines to achieve the best surface finish and rust retardation.
Parameter | Recommended Specification |
Appearance and Odour | Colorless to pale yellow liquid with a faint amine odour |
pH Level | 13.5 to 14.0 |
Specific Gravity | 1.01 to 1.03 at 30 degrees Celsius |
Water Solubility | Completely soluble in water |
Recommended Dosage | 300 to 500 ppm |
Note: The exact required dosage between 300 and 500 ppm will depend heavily on the specific feed water quality and the target pH requirement of the plant.
Safe Handling and Storage Guidelines
SURINSE is a strongly alkaline liquid and requires proper industrial safety protocols. Workers must wear splash goggles, a chemical-resistant coat, rubber gloves, boots, and a vapor respirator during chemical handling and application. Any splashes on the skin or in the eyes must be flushed immediately with plenty of fresh water, followed by medical attention if required.
For maximum stability, keep the containers tightly closed and store them in a cool, dry place. Under proper storage conditions, the product maintains a guaranteed six-month shelf life.
