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.

Rodine 2010 Corrosion Inhibitor for Boiler Chemical Cleaning – ChemEqual

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.

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.
