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.

Effective Sulfuric Acid Pickling with Rodine 85 – ChemEqual

Long term use of metal components in industries often makes them susceptible to formation of rust and surface distortion by scaling. In order to maintain surface quality and remove rust, acid treatment is employed. The metal parts are dipped in acid baths to oxidize and remove hard scales and rust layers. But since all acids have a corroding tendency with metals, acid treatment forms a root cause for concern particularly due to abrasive and corrosive loss of precious base metal leading to surface pitting and distortion.

Acid inhibitors are administered in acid pickling baths to prevent loss of base metal after proper pickling. It also helps to extend the life of acid baths. Using of inhibitor in acid solution limits the acid attack on base metal, therefore minimizing base metal loss. A potent acid inhibitor helps to alleviate acid attack on the base metal once the scale has been removed, lending protection to the surface and optimizing acid utilization.

Rodine 85 serves as a soluble, low foaming, liquid corrosion inhibitor formulated for use in conventional sulfuric acid pickling operations. It is an amalgamation of 1,3-Diethyl Thiourea, Formaldehyde, substituted Triazine & O-Toluidine, Propargyl Alcohol and detergent. Rodine 85 is effective on any type of steel, and can be used at any acid concentration. Rodine 85 is an effective inhibitor for phosphoric and acetic acids, as well as sulfamic, citric, oxalic, and sodium bisulfate solutions in pickling and industrial cleaning operations.

Rodine 85 dosage greatly depends on the type of metal, the temperature of operation and the sequence of cleaning operation. The recommended amount of Rodine 85 to be used for pickling is always given in percent by volume of the concentrated acid, regardless of the degree of acid dilution used. RODINE 85 should be used at a concentration ranging from 0.05 to 0.30 percent by volume of the diluted acid regardless of the degree of acid dilution used. In addition, it is 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.

Rodine Acid Inhibitor

Rodine Acid Inhibitor can be regarded as a range of acid corrosion inhibitors that are referred to as the worldwide standard for acid inhibitors. These series of inhibitors have been specially formulated to bring about protection of base metals from acidic corrosion effectively.

Let us first be enlightened about acidic corrosion and its effects on metals.

Acidic treatment is critical in providing protection to the base metals utilized in the industries against rusting and scaling. This acidic treatment is generally proceeded with to eradicate scale and rust but instead it brings about the abrasion of metals as they exhibit corrosive properties. This process not only changes the metal characteristics but is also responsible in causing the loss of base metals after acid pickling. Acidic Corrosion cause gradual wearing away of material by acidic compounds.

This acidic corrosion is considered to be an electrochemical process directed by the diffusion of moisture, availability of acidic pollutant on the metal surfaces and oxygen. This necessitates the requirement of acid inhibitors to help in hindering the acid attack on base metal, thereby aiding in to reduce the economic loss in various industrial sectors. The type and concentration of the acid inhibitor used is generally derived by the type and properties of the metal to be protected and the conditions under which the metal is to be treated.

Rodine Acid Inhibitor helps in reducing iron build-up along with aiding in eliminating chances of over pickling. These inhibitors account for better finish and appearance. These ranges of inhibitors include products that have been formulated to be used in most acid cleaning operations without hindering the productivity.
