One-Step Steel Treatment

Rassonil


Roy Research and Technology
has been promoting energy conserving, renewable technology that produces no wastes and saves money for users since the early 1980s. 

Rass-O’-Nil®  treats the steel and deposits an ultra-fine conductive polymerised metallic phosphate deposit. Powder-coating, e-coatings, electroplating, and paint adhere better and stronger to the Rass-O’-Nil treated steel surface. Extra anchor points on the Rass-O’-Nil treated metal surface improve the finish coating’s bonding and adhesion with the Rass-O’-Nil treated steel.Rass-O’-Nil’s conductive deposit enhances the electrostatic bonding for stronger coating adhesion. Rass-O’-Nil pre-treatment reduces the process time and running cost considerably, along with quality surface preparation. The finishing has longer-term corrosion protection than before.

We believe in using low cost renewable resources eschewing waste producing resources and recycling wastes wherever possible. There is profit in using fewer resources and producing less waste.

  • Rass-O’-Nil makes the steel pre-treatment process simple, economical, and enhances the finish quality.
  • Rass-O’-Nil® Steel Treatment does not produce any waste.
  • The Rass-O’-Nil steel treatment and pickling process saves water because rinsing is eliminated.
  • Rass-O’-Nil Steel Treatment reduces carbon emissions because the seven tank 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.

It is not just a matter of spending less on input resources for manufacturing but also consuming lesser resources and  producing less waste to produce a quality durable product built to last.

Rass-O’-Nil stringently satisfies ASTM B117 (USA) and IS: 13515-1992 (Indian Standard). The Rass-O’-Nil deposit does not come off from the steel even when the metal is bent up to 180°, punched, drilled or heated up to 400° C.

The Rass-O’-Nil treated metal surface sealed with a finish coat withstood more than 900 hours of salt spray test, passed the 1.5 kg scratch test, and adhesion test.

Rass-O’-Nil treated steel surfaces sealed with a finish coat, left in the open atmospheric conditions for years, do not allow corrosion beneath powder coating, e-coating, paint, and galvanizing.

One kilogram Rass-O’-Nil covers up to 750 square feet on fresh hot rolled steel sheet and up to 960 square feet on fresh cold rolled steel sheet. Rass-O’-Nil’s cost per square feet is extremely economical.

One-Step Steel Pickling and Passivation

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:
  1. Rass-O’-Nil® Steel Treatment does not produce any waste and does not need water.
  2. The Rass-O’-Nil steel treatment and pickling process saves water because rinsing is eliminated.
  3. Rass-O’-Nil Steel Treatment reduces carbon emission because the conventional seven tank steel treatment process is replaced with a clean one-step process.
  4. The Rass-O’-Nil steel pickling process eliminates all the hazardous/toxic chemicals, such as strong acid.
  5. Rass-O’-Nil makes the steel pickling and passivation process simple, economical, and prevents corrosion on steel.

Save food from Climate Change

Climate change will pose sharp risks to the world’s food supply in coming decades, potentially undermining crop production and driving up prices at a time when the demand for food is expected to soar, scientists have found”,  – The New York Times: “Climate Change Seen Posing Risk to Food Supplies”

Renewable Nitrogen Fertilizer Plantee replaces chemical fertilizers and protects agriculture from global warming:

The manufacture of chemical fertilizer is an energy-intensive process, consuming non-renewable natural gas and releasing greenhouse gases like Carbon Dioxide, Nitrous Oxide and Methane. Nitrogen-based fertilizers are made from ammonia, which consumes five per cent of the natural gas produced globally. This quantity of natural gas amounts to two per cent of the total energy consumed globally.

Plantee biomass fertilizer replaces chemical fertilizers and stops the emission of greenhouse gases emitted during the production of chemical fertilizers.  Plantee biomass fertilizer is a renewable resource and helps reduce global warming.

It may surprise many people but agriculture today, is one of the major causes of pollution. The indiscriminate use of chemical fertilizers has not only resulted in reduced agricultural productivity, but also in pollution of groundwater resources and marine eutrophication.  Urea and DAP fertilizers make soil acidic.

Plantee aids soil pigmentation and restores the soil’s natural appearance discoloured by chemical fertilizer over use. The chemical fertilizer run-off from the fields increases the nutrient levels in lakes and rivers and results in a spurt in algal blooms. These algae may take up all of the oxygen from the water and thus ruin other marine life. Also, leaching of the residual nitrate in groundwater has resulted in nitrate concentrations above the permissible level.

Plantee increases crop durability and yield and can be the answer to world hunger: 

Roy Research and Technology has successfully grown Swarna rice using solely Plantee in Birbhum district of West Bengal, India. This rice was tested and found to have higher starch, carbohydrate and protein content. It also withstood stress situations like flooding and drought.

Plantee protects the plant from bacteria and fungus that cause stem and root rot by building immunity. Warm and wetter weather and flooding increases the spread of fungus and bacteria on plants and crops destroying crop yield.

Plantee produces flowers that stay fresh after cutting much longer and increases the vase life of flowers. Plantee helps the flowering plant bear warmer weather because of climate change.
