Metal Passivation using Rodine 85 for Sulfuric Acid Pickling - ChemEqual

Derusting and descaling operations on industrial metal components require the use of strong mineral acids like sulfuric acid to maintain surface quality. It employs the use of acid baths for oxidative removal of alkali scales and mineral oxide deposits. But mineral acids have a tendency to corrode metal surfaces as well rendering them distorted by formation of pits and loss of base metal.

To retard the corrosive nature of acids, the pickling liquor used in acid vats is primarily composed of a pickling acid such as sulfuric acid mixed with an acid corrosion inhibitor. These inhibitors do not reduce the efficiency of the liquor but tend to passivates the base metal surface preventing pitting and corrosion. These passivating chemicals greatly reduce maintenance costs and extend equipment life while optimizing acid utilization and quick operations.

Rodine 85 is a low foaming soluble liquid corrosion inhibitor specifically designed for acid baths that use sulfuric acid as the pickling reagent. It is a synergistic organic blend of 1,3-Diethyl Thiourea, Formaldehyde, substituted Triazine & O-Toluidine, Propargyl Alcohol and detergent that is effective on a wide range of metal surfaces and can be ideally dozed over a wide range of acid concentrations. . Rodine 85 serves as an effective inhibitor for phosphoric and acetic acids, as well as sulfamic, citric, oxalic, and sodium bisulfate solutions in pickling and industrial cleaning operations.

It is recommended that dosage of Rodine 85 to be used for pickling should always be in percent by volume of the concentrated acid, regardless of the degree of acid dilution used. Ideal concentration ranges from 0.05 to 0.30 percent by volume of the diluted acid. In addition, it is also recommended that Rodine 85 inhibitor be used at a concentration not less that 0.5% by volume of the concentrated liquid acid or not less that 0.5% by weight of the concentrated solid acid, regardless of the temperature of the industrial cleaning operation.

WHAT MAKES RODINE 213 THE BEST ACID INHIBITOR FOR OVER TWO DECADES

Rodine 213 has remained the most popular choice till date for Hydrochloric Acid pickling and plant cleaning.

Hydrochloric acid replaced Sulfuric acid as the pickling liquor since it pickles substantially faster with minimal base metal loss. The highly reactive chloride ion in the acid is the reason for high efficacy in the cleaning procedure. It is utilized for cleaning metals with alloy content of 6% or less. An acid inhibitor must be added to the pickling solution to keep the metal surface from dissolving or getting pitted. Such pickling acid inhibited liquor is called "Inhibited HCL" and is a mix of Hydrochloric acid solution in water (3% to 10%) and an acid corrosion inhibitor which in itself is a mix of natural and synthetic chemicals that adsorb on the metal surface during pickling.

Rodine 213 is a superior synthetic blend of keto-amine complex substitutes with non-ionic surfactants, alcohols and solvents particularly intended to restrain hydrochloric acid corrosion on metal surfaces during modern operations like surface cleaning and pickling. It is effective over an extensive variety of metal surfaces like Iron and Steel, copper and metal. Rodine 213 is a high foaming anti-corrosion additive with a high viability at dispersing oil and grease and is perfect for HCL based pickling liquor systems particularly before plating.

It guarantees metal surface protection during procedures including lime scale removal from kettle and pipework and from evaporating plants, removal of oxide residue from iron, steel, metal and copper. Rodine 213 is free from chlorinated hydrocarbons and heavy metals like arsenic and lead. It can be synergized with Hydrochloric acid pickling in stipulated dozes both by circulation method and by drench and flush operations. Rodine 213's exceptional quality and thermal stability makes it a perfect acid corrosion inhibitor for improvement of the pickling procedure by pre-warming the liquor bath with the inhibited acid system. It additionally works as an excellent acid fume suppressant.

Its key components can be summarized as follows:

Rodine 2010 - Corrosion Inhibitor for Boiler Chemical Cleaning

Boiler systems and pipelines associated with power plants and heating systems often face the problem of mineral scaling on the inner linings and transmission bends. This is mainly due to the residual hardness of the coolant water used. While treated water is essential, minute traces of partially soluble salts of calcium, magnesium, strontium, as well as due to silica and ferrous oxides. While scaling may lead to choking and rupture of transmission pipes, oxidation due to unregulated pH of boiler feed water can result in corrosion and pitting of metal. Thus various boiler scale removal chemicals are employed to clean and maintain optimum operation efficacy of boiler systems.

The two primary choices include Ammoniated EDTA and Ammoniated Citric acid for cleaning. They are both weak organic acids and remove mineral scales and oxides by oxidation and metal ion chelating. But as the case with all metal-acid processes, acids often corrode and cause damage to metal surfaces. And damaged/abraded inner linings of boiler pipes have a risk of exploding at high water temperature and pressure. Thus appropriate acid inhibitors are needed to limit the acid attack on base metal, therefore helping check economic loss and ensure safety.

Rodine 2010 is by far the most popular choice as corrosion inhibitor for chemicals used in boiler cleaning. It is a low toxicity, non-flammable, highly soluble low viscosity liquid metal loss inhibitor for use in tetra ammoniated EDTA and tetra ammoniated Citric acid cleaning solutions. Rodine 2010 not only minimizes ferrous metal loss during chemical cleaning of power plant boilers but also effectively prevents pitting and crevice corrosion of metal surface. Rodine 2010 has a maximum operating temperature of 350°F when used with EDTA and 200°F when used with Citric acid cleaning solution with an operational life of 24hours. Laboratory testing has confirmed that it is more soluble than other commercial inhibitors at elevated pH and advantageously permits post-oxidation and dissolution of metallic copper deposits at significantly higher rates than other commercial corrosion inhibitor chemicals.

It imparts excellent pickling and modifies the metal surface to help in the prevention of corrosion.

Acidic treatment is important in providing protection to the metals used in the industries against scaling and rusting. This acid treatment is mostly carried out variously to assist in the eradication of scale and rust but instead & often triggers abrasion of metals as they exhibit corrosive properties. This process not only influences the metal properties but also causes loss of base metals after acid solution pickling. Acidic Corrosion often causes gradual wearing off of material by acidic compounds.

This acidic corrosion is an electrochemical process which is directed by the diffusion of moisture, oxygen and availability of acidic pollutant on the metal surfaces. This brings about the requirement of acid inhibitors to aid in limiting the acid corrosion on base metal, therefore helping reduce the economical loss in several industrial sectors. The type and concentration of the corrosion inhibitor used is generally derived based on the type and properties of the metal to be protected and the conditions under which the metal is to be treated.

NALCOOL 2000 - Automobile Coolant Corrosion Inhibitor

Corrosion and scaling in automobile cooling systems is primarily by chemical reaction of oxidizing agents in the coolant on the metal components. The type and nature of materials present at heat exchanging surfaces, the temperature of the system, pH and type of corrosive elements present in the coolant determine the type of inhibitor package needed.

Conventional water based coolants constantly need additives in the form of mineral inhibitors such as phosphates, nitrites and borates for poplar heat exchange surface metals like aluminium, copper etc along with other parts made from cast iron & mild steel. Absence of suitable inhibitors can cause corrosion, metal cavitation, scaling and cause leaks by destruction on rubber gaskets and head caps. Liquid coolant additives serve ideally as easy to use blends that can be directly mixed with coolant water for easy and quick anti-corrosive action on coils, coolant pump and radiator fins.

Corrosion inhibitors are generally blends of chemicals added to the coolant water to reduce material loss and system damage due to oxidation. The prerequisite is a passivation agent to coat the metal surfaces preventing further corrosion followed by neutralization of oxidizing ions in the coolant thus reducing cavitation. Best corrosion inhibitors need to be fast acting and thermally stable so as to operate at high temperatures and high coolant flow rate. Nitrite, Borate, Silicate and Polyacrylate formulations seem to be the most popular as corrosion and rust inhibitors. This is due to the fact that they are able to remove most oxidizing agents in common coolants while passivating metal surfaces for a long lasting corrosion control. The only requirement is to keep a steady inhibitor concentration in the system.

NALCOOL 2000 manufactured by Nalco Company is a synergized inhibitor blend for metal passivation and sale suppression as a water soluble corrosion inhibitor. It has been designed for all common engine cooling systems and is ideal to protect ferrous metals, copper & its alloys, aluminium etc. as well as rubber gaskets and non-metallic components within the cooling system.

Corrosion
Generally, inhibitors show a great acknowledgment as the best way to battle against corrosion issue in the commercial enterprises attributable to its unrivaled anticorrosive properties. The inhibitor is chemically adsorbed on the metal surfaces and builds up a protective slender layer or film as a consequence of interaction between the inhibitor particles and the metallic surface. This corrosion film is only the oxide which is created because of a chemical reaction between the metallic surface and the oxygen present in the environment. The inhibitor prompts an arrangement of a shield layer by oxide protection of the base metal. Corrosion Inhibitors can be divided according to their chemical properties as organic or inorganic and the component of activity as anodic, cathodic or mixed.
