Discussion and Research on the Process of Steam Cleaner
Steam Cleaner process is generally in order to improve the wear resistance and corrosion resistance of stainless steel to make it brighter and improve the corrosion resistance of stainless steel products.
(A) the use of acid solution to remove iron and steel on the surface of the scale and corrosion of the method known as the Steam Cleaner. (Fe3O4, Fe2O3, FeO, etc.) reacts with the acid solution to form a salt, which is dissolved in the acid solution and is removed. Steam Cleaners are made of sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, chromic acid, hydrofluoric acid and mixed acid. *** commonly used is sulfuric acid and hydrochloric acid. Steam Cleaner technology is mainly impregnated Steam Cleaner method, spray Steam Cleaner and acid paste rust method. General use of impregnated Steam Cleaner method, mass production can be used spray method. Steel parts are typically in a 10% to 20% by volume sulfuric acid solution with a Steam Cleaner at a temperature of 40 ° C. When the iron content in the solution exceeds 80g / L, ferrous sulfate exceeds 215g / L, the Steam Cleaner liquid should be replaced.
At room temperature, with 20% to 80% (volume) of hydrochloric acid solution for steel Steam Cleaner, less prone to corrosion and hydrogen embrittlement phenomenon. Since the corrosion of the metal on the metal is very large, the need to add corrosion inhibitor. After cleaning the metal surface into a silver white, while passivation of the surface, improve the corrosion resistance of stainless steel. (2) In order to eliminate the surface adsorption of diatomaceous earth carrier, reduce the peak tail, the carrier before use to be Steam Cleaner or alkaline washing treatment. Steam Cleaner is the carrier with 6mol / L hydrochloric acid for 2h or concentrated hydrochloric acid heating for 30min, filter, washed with water to neutral, drying. Steam Cleaners can remove impurities such as iron, aluminum, calcium, magnesium and the like on the surface, but can not remove the silanol groups. The Steam Cleaner carrier is suitable for the analysis of acidic samples. (C) steam cleaning agent commonly used acid: hydrochloric acid, sulfuric acid, nitric acid, phosphoric acid, hydrofluoric acid. Be sure to add Steam Cleaner to the Steam Cleaner to prevent corrosion of the metal. Wire Steam Cleaner after the neutralization and lubrication, so its process includes rust, Steam Cleaner, washing, coating, drying and other 5 to 8 processes. Due to the different production processes of various wire, the Steam Cleaner process is also different.
As a stainless steel surface treatment technology experts, stainless steel Steam Cleaner in the continuous innovation and development, new technology, new technology and new equipment for the stainless steel surface treatment progress is made no small contribution.
Steam cleaning agent for a variety of models of stainless steel cold rolling after the Steam Cleaner bright treatment, play degreasing, rust, light, passivation rust, fog and other effects, especially for stainless steel cold rolling line operation, greatly Shorten the cleaning time, while suppressing the generation of smoke, greatly improving the production environment, greatly reducing the corrosion rate of metal, *** the final surface of the product clean and clean, to achieve the effect of chemical polishing. Applicable to various types of stainless steel. Stainless steel bright Steam Cleaner from the degreasing agent, brightener, high efficiency corrosion inhibitor, antifogging agent and other complex, degreasing, light, passivation step by step, fast, high efficiency, large capacity, long service life , Almost no corrosion of the metal matrix, the cleaning process is basically no acid mist. Multi-functional steel surface treatment solution rust speed, good effect, and the construction process is simple, saving time.Use this product to deal with the steel surface, the metal surface of the protective film has a good anti-corrosion, stored in the air more than ten Day does not rust; and does not damage the metal material, no hydrogen embrittlement and other defects; can significantly improve the adhesion of various paint film. Because it does not contain strong acid, alkali, zinc, manganese, chromium and other harmful ions and nitrite and other harmful substances, in line with industrial supplies emission standards. The product is non-toxic, non-burning, the use of safety, environmental pollution.
