The Steel Pickling and Treatment process in steelmaking and Steel Pre-treatment before coating uses thousands of litres of water for rinsing and washing after treatment with hydrochloric acid, chromate and phosphate solutions and other alkaline or acidic chemicals.
The Rass-O’-Nil One-step Steel Pickling, Passivation and Treatment technology does not need the steel to be rinsed with water after pickling and eliminates hazardous chemicals like strong acid in steel treatment.
The Rass-O’-Nil one-step steel pickling and passivation technology eliminates the hazardous acids and rinse water from the steelmaking and steel pre-treatment industry.This eliminates hydrogen embrittlement caused by strong acid like hydrochloric or sulphuric acid.
The conventional steel pickling and treatment processes in steelmaking and steel pre-treatment before painting use a hazardous chemicals like strong acids (hydrochloric and sulphuric acid, which produce a lot of waste) and other chemicals like alkaline degreasers and phosphates.
Steel surface preparation and treatment plays a major role in the steel finish quality:
If the steel surface is not cleaned properly or if the surface has oil, rust or dirt, or scale the adhesion between the steel and the finish coat becomes weak and causes the finish coating to fail.
The steel treatment is needed to provide a protective deposit on the metal surface to resist corrosion under the finish coating.
During these three treatment processes the steel is dipped in water to rinse any excess acid, alkali, or phosphate depending on the process. The rinse water is polluted with the chemicals that are washed off from the steel.
Rass-O’-Nil® is the one-step steel treatment, pickling and passivation nano-technology. Rass-O’-Nil treats and pickles the steel and deposits an ultra-fine conductive polymerised metallic phosphate deposit and prevents corrosion on steel.
The treated steel does not require a protective oil coat to keep it from corrosion unlike the strong acid pickling or shot blasting process. So there is no need to degrease the steel before powder coating, galvanizing or painting.
Five reasons to use Rass-O’-Nil One-step Steel Pickling, Passivation and Treatment:
- Rass-O’-Nil® Steel Treatment does not produce any waste and does not need water.
- The Rass-O’-Nil steel treatment and pickling process saves water because rinsing is eliminated.
- Rass-O’-Nil Steel Treatment reduces carbon emission because the conventional seven tank steel treatment process is replaced with a clean one-step process.
- The Rass-O’-Nil steel pickling process eliminates all the hazardous/toxic chemicals, such as strong acid.
- Rass-O’-Nil makes the steel pickling and passivation process simple, economical, and prevents corrosion on steel.
Rass-O’-Nil Water-saving Steel Pickling and Treatment Technology was tried at Tata Steel:
“For several years — Tata Steel’s R&D and Roy Research and Technology made a joint effort towards the optimization of the chemical’s uses and physical testing for plant implementation for the development of the metal surface preparation and pre-treatment technology through lab and plant trial. This metal surface preparation and pre-treatment technology polymerised with a polymorphous character.
For several years — Tata Steel’s R&D invested considerable amounts towards adapting the new technologies and Roy Research and Technology has also invested certain amounts and time in developing these technologies.
After thorough testing at the lab and plant level, these new technologies were well accepted by Tata Steel and Roy Research and Technology. The following are those technologies are the new developments of poly-phosphating and poly-metallic phosphate – Flexo and Galvo Technologies for HR, CR, Galvanneal, and tubes (hereinafter referred to as New Technologies.)” – Excerpt from text of Agreement
We want to introduce a clean steel pickling and treatment technology to the steelmaking and steel using industry that produces no waste and uses no water.
