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:

  • Modifies metal surface to prevent corrosion

Sanosil – Hydrogen Peroxide with Silver as an all purpose disinfectant at ChemEqual

Hydrogen Peroxide has long been known for its oxidizing capabilities. But, its unstable nature made it highly unsafe and short lasting. Use of Silver as stabilizer and activator is the ideal solution to this problem. Silver stabilized hydrogen peroxide is efficiently used for soil fumigation, air sanitation, water disinfection, even surface disinfection. Silver with antimicrobial properties and the intense oxidizing effect of H2O2 can be used as an eco-friendly and powerful disinfectant with an assortment of utilizations.

Sanosil-Silver H2O2 is the only EU Biocide Article 95 compliant Hydrogen Peroxide/Silver based disinfectant approved for use in the UK by the HSE and NHS and used widely by the water treatment sectors, decontamination sectors as well as home care, hospitality and pharmaceutical sectors worldwide. The product is specified by the NHS to combat MRSA. The unique disinfection properties of silver stabilized hydrogen peroxide are intrinsically and environmentally safe to use in medical, clinical and most other built environments.

Sanosil disinfectant works in a combined 2-phase effect of the main ingredients. The nascent oxygen from hydrogen peroxide attacks cell walls of microorganisms upon direct contact. Nascent oxygen denaturizes the cell wall and disrupts cytoplasm stability. This effect is boosted by silver ions that disrupt protein activities associated with reproductive and metabolic systems and deactivates them resulting in rapid cellular degradation and microbial death.

Silver H2O2 disrupts the cellular membrane of microorganisms and attacks internal cell structure and processes. H2O2 decomposes into water and oxygen (2H2O2 –> 2H2O+O2) and traces of nano silver form residue on the disinfected surface. These silver traces are invisible and non-toxic but actively and effectively counteract re-germination and re-growth.

Common disinfectants in the market focus their effect on one single point of attack which may be sufficient to kill germs in the short term however; monovalent biocides result in evolution of resistant germ strains and become increasingly ineffective over time. Sanosil is regarded as “smart” technology and less problematic as it does not allow development of resistance.

To date and based on ongoing worldwide studies, there is no human pathogen that has managed to develop a resistance to Sanosil.

Sanosil range of formulations for professional use is predominantly preferred as:

  • surface cleaner
  • low level water system continuous dosing agent
  • water distribution system treatment for bio-film removal
  • dental chair unit (DCU) waterline additive

The available formulations are:

Sanosil S003 (1.5% H2O2): Fogging aerosol disinfectant for low level germ loads

Sanosil S006 (3% H2O2):  Fogging aerosol disinfectant for moderate level germ loads

Sanosil S010 (5% H2O2): Fogging aerosol disinfectant for high level germ loads and particularly effective in combating bacteria, viruses, yeasts, mildew, fungi, molds spores and malodorous smell.

As per the EEC, WHO, and the USEPA, Sanosil silver hydrogen peroxide represents no health threats to people. Even Switzerland, France, Australia and Germany have approved silver hydrogen peroxide for drinking water sanitation.

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 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 92B Acid Inhibitor for Food Processing equipment cleaners

Effective cleaning of equipment in the food processing industry is required to reduce chances for contamination of during preparation, processing, storage & serving. Cleaning prevents attraction of lower life forms like food pathogens, increases equipment life, boosts employee morale and efficiency and accounts for aesthetic considerations of consumers. The primary cleaning agent is water; free from disease producing organisms, toxic metal ions and objectionable taste & odor. But such quality of cleaning water is hard to achieve and chemicals are tailored to meet cleaner specifications based on water composition and operation type.

Acid Type Cleaners & Corrosion:

Acid cleaners are used in the food processing industry for milkstone removal and cleaning equipment like broth tanks, ingrediators etc. A wide choice of acid type cleaners for mineral scale removal exist today but organic acids and blends of organic acid type cleaners and chelating agents have found much popularity in recent times. This is because they are much less corrosive than mineral acids and alkaline cleaners. Citric acid and EDTA are frequently used for this purpose owing to a better pH regulation and less aggressive surface action.

Nevertheless, acid cleaning chemicals are corrosive to the base metal and are responsible for corrosion & pitting of surface. Inhibitors for Citric Acid descaling solution are usually applied at very low concentrations (1000-3000 ppm) to provide upto 99.8% corrosion inhibition during acid cleaning processes. Depending on the acid type used, specific corrosion inhibitors are designed to remove scales and deposits from equipment while minimizing base metal loss. They are of mostly polymeric origin and act by forming chelating structures, proving high efficiency as inhibitors in acid chemical cleaning operations.

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.
