1. NALCOOL 200
Corrosion Inhibitor

2. NALCOOL 2000

3. Here, we will get to learn about Nalcool 2000 and its applications
But before that, first, we need to understand how and why corrosion
occurs and the role of corrosion inhibitors

4. What is Corrosion?
• Corrosion may be regarded as the deterioration of materials, specifically
metals, by chemical interaction with their environment
• It is the electrochemical oxidation of metal in reaction with an oxidant such
as oxygen
• Corrosion can be locally concentrated to form a pit or crack, or it can extend
across a wide area corroding the surface more or less uniformly
• It brings about the degradation of the useful characteristics of materials and
structures including strength, appearance and permeability to liquids and
gases

5. What is Corrosion?
• The consequences of corrosion are innumerable and diverse and the
effects of these on the efficient operation of equipment or structures are
often more critical than the simple loss of a mass of metal
• Few of the consequences are noted below:
– Reduction of metal thickness leading to loss of mechanical strength
– Hazards or injuries to people arising from structural failure or breakdown
– Reduced value of goods due to deterioration of appearance
– Loss of time in availability of profile-making industrial equipment
– Perforation of vessels and pipes allowing escape of their contents and possible harm to
the surroundings
– Contamination of fluids in vessels and pipes
– Loss of technically important surface properties of a metallic component
– Mechanical damage to valves, pumps, etc, or blockage of pipes

6. How to prevent corrosion?
• Prevention of corrosion can be controlled in different ways, of which few are
noted below:-
– Conditioning the metal: This can be carried out in two ways:
• Coating the metal for the sake of interposing a corrosion resistant coating between
metal and environment
• Alloying the metal to produce a more corrosion resistant alloy
– Conditioning the corrosive environment: This can be carried out in two ways:
• By removal of oxygen – Eliminating oxygen can reduce the chances of occurrence of
corrosion
• Applying Corrosion Inhibitors - A chemical additive, which, when added to a
corrosive aqueous environment, decreases the rate of metal wastage
– Electrochemical control : The rate of corrosion reactions may be controlled by
passing anodic or cathodic currents into the metal

7. Corrosion Inhibitors
• Historically, inhibitors manifest a great acceptance as the only way to fight
against corrosion problem in the industries owing to its superior
anticorrosive properties.
• Corrosion Inhibitors can be categorized with respect to their chemical nature
as organic or inorganic and the mechanism of action as anodic, cathodic or
mixed.
• Anodic inhibitors play its role by forming an oxide film on the metal
surface resulting in a large anodic shift of the corrosion potential.
• This shift force the metallic surface into region of passivation and hence
they are referred to as passivator, whereas cathodic inhibitors slow down
the cathodic reactions to limit the diffusion of reducing ions to the surface of
the metals.
• On the other hand, mixed inhibitors work by reducing both anodic and
cathodic reactions.

8. NALCOOL 2000
• Classified as a mixed inhibitor as it exhibits the properties of both anodic
and cathodic inhibitors
• Nalcool 2000 serves to be a multipurpose nitrite based corrosion inhibitor
designed specially for inhibiting rusting or corrosion of metal by the
formation of a passive coating of protective film on the metal surface
• Nalcool 2000 consists of a combination of ferrous and non-ferrous corrosion
inhibitor, scale inhibitor, non-carbonate buffer, dispersant and leak detection
dye
• Nalcool 2000 has a varied range of applications. It is used as -
– Cooling Water Corrosion Inhibitor
– Coolant Corrosion Inhibitor

9. NALCOOL 2000
• Nalcool 2000 underlines many key benefits and features which are as
follows:-
– Multi-metal corrosion protection
– Scale prevention
– Leakage and burst protection
– Saves power more than 30%
– Temperature resistance – 29 deg C to 215 deg C
– Extends system life
– Enhances system efficiency

10. Applications of Nalcool 2000

11. COOLING TOWERS
 Corrosion and scale are significant
problems in Cooling Towers.
 Requires yearly acidic treatment to
remove scale.
 Industrial cooling tower water
traditionally is treated with chemical
corrosion and scale inhibitors
 Nalcool 2000 serves as an
effective corrosion inhibitor that is
used as a Cooling Water Treatment
chemical.

12. AUTOMOBILES
 Corrosion through electrolysis is a
common problem faced while using
normal coolant.
 Corrosion is identified by leaking
coolant, appearance of black holes on
the heater, etc.
 It can be usually tackled by using
some sort of inhibitor along with the
coolant.
 Nalcool 2000 serves as an
effective corrosion inhibitor that is
used as a Coolant corrosion inhibitor.

13. Nalcool 2000 – Corrosion Inhibitor is formulated to inhibit
different types of corrosion and is available in various compositions
and pack sizes to suit different industrial applications
