Acid Corrosion Inhibitor is designed specifically to inhibit the acidic attack on various metals such as Brass, Copper, Tin, Nickel, Zinc, Lead, Galvanized surface and all other type of steel.

1. Rodine range of Acid Inhibitors

2. ACID CORROSION INHIBITOR - INTRODUCTION
Acid Corrosion Inhibitor stands
out to be an effective and most
usedproduct for providing
complete protection to base
metals against the corrosiveattack
of most acids.

3. Before discussing more about acid corrosion inhibitors,first
let us get an insightinto whatcorrosion is allabout and why
acidiccorrosion occurs

4. • Most industries allover the world involve the usage ofmetals and their
alloys in any form–be it forraw material purpose orfor using them in the
constructionoftheir machine parts.
• Different kinds of metals, till date, remain an indispensible part of any
industryirrespective of their natureofoperation.
• Thesemetals or metal structuresrequireproper maintenance or else they
undergoslow deterioration by the action of atmospheric gases, moisture or
other chemicals.
• Thischemical phenomenon ofa metal undergoing destructiondue to
environmental factors is referredto as Corrosion.
CORROSION

5. CORROSION
• Corrosion may be regarded as the gradual abrasion or
deterioration of a metal by electrochemical orchemical reactions
with its environment.
• On account of corrosion, the useful characteristics of a metal such
as malleability, ductility and electrical conductivity are gradually
lost.
• Rusting of iron can be referredto as a common example of
corrosion.
• The rate and extent of corrosionmainly dependson the nature of

6. ACIDIC TREATMENT
• To prevent metals from corroding, protective coatings ofdifferent types are
added. Theoutermost surfaceofthe base metal usually consistsof impurities
like scale, rustand grease.
• Thesesubstances,ifpresent at the time ofcoating, will give porousand
discontinuous coatings.
• Inorder to get a uniform, smooth and coherentprotective coating, these
substancesare to be removed by certainmethods which include the
application of acidic treatment.

7. • Thisprocessof the removal ofthe oxide scales and corrosionproducts (rust)
from the surfaceis called descaling. In this process, the base metal is dipped
inside the acid solution at highertemperatures.
• Theacid penetrates throughcracksand poresof the scales and then their
dissolution takes place.
• Acids like sulphuricacid, hydrochloric acid and nitric acid are used under
dilute conditions.

8. NEEDFOR ACID CORROSION INHIBITOR

9. ACID CORROSION INHIBITOR
• Prolonged exposure ofthese metals into the acidic solution may cause
gradualwearing ofthe metal surfaces.In orderto prevent this type of
corrosion,inhibitors areadded.
• Acid Corrosion Inhibitorgenerally helps to impede corrosionby adhering
to the metal surfacesand forms protective films which servesto prevent
both cathodic and anodic reactions.
• Acid CorrosionInhibitor is designed specifically to inhibit the acidic attack
on various metals suchas Brass,Copper, Tin, Nickel, Zinc, Lead, Galvanized
surfaceand allother type ofsteel.
• It can be used for blending orformulating pre-inhibited descalant or acidic
cleaners.

10. RODINE ACID INHIBITORS
• Rodine range of acid inhibitor products serve as the worldwide standard for
acid inhibitors.
• Rodine inhibitors have been formulated to provide effective protection to
basemetals fromacidic corrosion
• Helps in reducingiron build-up
• Helps in improved protection of equipments
• Accountsforbetter finish and appearance

11. RODINEACID INHIBITORS
• Aids in eliminating chancesof over pickling
• Rodine range of products include inhibitors that are designed for use in most
acid cleaning operations without affectingtheproductivity
• Finds application in thefollowing industries:
Iron & Steel, Power Station, Petrochemical & Refineries, Heavy Engineering
Industries, Cement, Glass & Ceramic Industries, Sugar Processing Industry,
MiscelleneousManufacturingIndustry,etc.
