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.

Effective Sulfuric Acid Pickling with Rodine 85

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

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.

RODINE ACID INHIBITOR

Rodine Acid Inhibitor can be viewed as a range of acid corrosion inhibitors that are alluded to as the overall standard for acid inhibitors. These bunches of inhibitors have been uniquely designed to provide protection to base metals from acidic corrosion viably.

But prior to that we should know about process of acidic corrosion and its consequences for metals.

Acidic treatment is important in giving protection to the base metals used in the commercial industries against rusting and scaling. This acidic treatment is by and large continued with to destroy scale and rust but in its place causes the abrasion of metals as they possess destructive properties. 

This procedure changes the metal attributes as well as responsible in bringing about the loss of base metals after acid pickling. Acidic Corrosion cause steady wearing away of material by acidic mixes.

This acidic corrosion is thought to be an electrochemical procedure coordinated by the dispersion of moisture, accessibility of acidic toxin on the metal surfaces and oxygen. This requires the prerequisite of acid inhibitors to help in hindering the acidic attack on base metal, in this manner supporting to alleviate the economic loss in different industrial division. The type and concentration of the acid inhibitor utilized is for the most part inferred by the sort and properties of the metal to be protected and the conditions under which the metal is to be dealt with.
