How the use of acid inhibitors prevents flash rusting during acid cleaning?

One of the crucial aspects of metal infrastructure maintenance is the regular cleaning process. Within this domain, Acid Cleaning emerges as a pivotal method renowned for its efficacy in eradicating rust, scale, and contaminants from metal surfaces across diverse industrial sectors. However, amidst its utility, a notable challenge looms: the occurrence of flash rusting. This phenomenon entails the rapid onset of rust, swiftly spreading across metal surfaces upon exposure to oxygen and moisture. It serves as a significant indicator, suggesting potential salt contamination, heightened humidity levels, or a combination of both factors. In the perpetual endeavour to combat corrosion, the emergence of flash rusting introduces a compelling element to the narrative of metal preservation.

Let us first try to understand what’s and whys of flash rusting. It is a rapid corrosion process that occurs when metal surfaces, stripped of rust and contaminants through acid cleaning, react with oxygen and moisture from the atmosphere. The freshly exposed metal becomes highly susceptible to oxidation, leading to the formation of iron oxide or rust. This type of rusting typically occurs within minutes after cleaning operations are completed. The rate of flash corrosion depends upon the amount of dissolved oxygen in the water, impurities present in the water, the amount of ionic compound on the metal surfaces, and the total drying time.

As we all know corrosion creates various effect that weakens the integrity of the entire infrastructure. It’s not just about the visible damage – it’s the ripple effect. It leads to losses worth over 900 thousand crores in India Annually. “As India moves towards a USD 5 trillion economy goal, dealing with a challenge like corrosion in projects should be a key focus area, said Rajamani Krishna Murti, president of Indian Stainless-Steel Development”
Role of Acid Inhibitors
Acid inhibitors are chemicals added to acidic solutions during the cleaning process to prevent flash rusting. These inhibitors also prevent corrosive reactions of acids with metal surfaces, extending longevity and reducing operational costs. By forming a protective layer, they shield the metal from direct contact with acids, inhibiting corrosion and enhancing durability. They combat corrosion, control its impact, improve resistance, prevent rust, and provide essential surface treatment.

Working Mechanism
Passivation: These inhibitors create a passivation layer, which act as a barrier, reducing the reactivity of the metal with free acid ions.
Chemical Reaction Inhibition: These complexes effectively block active sites on the metal, reducing the rate of oxidation.
Film Formation: Some form a thin film over the metal surface, creating a physical barrier that shields the metal from acid elements. This film helps prevent the initiation of corrosion reactions, thus minimizing the risk of flash rusting.
Variants

Different types of acids require specialized inhibitors for effective metal protection during cleaning processes:

Inhibitor for hydrochloric acid: Forms protective films to shield metal from corrosion during acid cleaning, ensuring durability in corrosive environments.
Inhibitor for sulfuric acid: Reduces corrosion rates and extends equipment lifespan in corrosive environments by forming protective films on metals during acid etching.
Organic Inhibitors: Compounds like amines, phosphates, and organic acids adsorb onto metal surfaces, forming protective films that inhibit corrosion during acid cleaning.
Inhibitors for sulfamic acid: Comprising diethyl thiourea, stabilizers, and surfactants, these inhibitors act as semi-foaming acidic corrosion inhibitors, ideal for pre-formulated descaling. Effective on various metal surfaces including Copper, Brass, Nickel, Tin, Lead, Zinc, galvanized surfaces, and all steel types.
In essence, specialized formulations tailored to each acid type are essential for effective corrosion prevention during cleaning processes. With Chemtex Speciality Limited’s expertise and innovative solutions, the battle against corrosion takes a significant step forward, ensuring a brighter and more durable future for metal-dependent industries.

The Evolution Of A Full Service Ad Agency

Let us first try and understand, what is a full service advertising agency all about? It is an agency that consists of various departments, which plan media, buy media, design the ad, write copy text, etc., under a single roof. Quite a few decades ago, the work of ad agencies was minimal, because there were not many brands and there were only few manufacturers, at that time. However, over the last few years, the need for advertising has increased as many new brands have emerged in the market. To differentiate their brands from others, marketers then sought the help of advertisers. These advertisers developed new and attractive ways to promote an existing brand to their target audience. This is how advertising evolved and the work of an ad agency grew. A Full service advertising agency now consists of multiple departments working together, which has become more of a necessity, in these current modern times of advertising.

There are four traditional ways of advertising – newspaper, magazine, radio and television. To keep up with the pace of the competitive markets, the art of advertising has also evolved in terms of media. Now, there are various new and emerging advertising mediums like billboards, online, covert, press ads, in-store advertising, etc. Full service advertising agencies have now grown in size. Various departments like social media advertising, outdoor advertising, transit, standees, etc. are designed and featured by various departments. A full service agency now thinks like a creative ad agency, to give the best output. They are now hiring experts in their respective fields, to give the best outcome to the brand owners.

One of the major steps of evolution seen in many full service ad agencies, was adding a specialized social media department. Social media is the new trend of advertising. Smart individuals with quick and witty brains are in high demand. This department advertises brands online, and creates a buzz on social networking websites. Another trendy way of advertising undertaken by full service ad agencies, are designing billboards and hoardings. Delivering messages instantly, and creating awareness about the product within seconds, is a task that only an efficient advertising agency can successfully carry out. In-store advertising is another popular style of advertising. It acts as a reminder to the customers, or pushes them for last minute shopping. Full service ad agencies hire skilled designers for this type of advertising, as the layout and design should be catchy and attractive to cross-sell to customers.

Brand advertising on trains, buses, taxis, etc. are in fashion. This contemporary medium of advertising is known as transit media. Full service ad agencies are coming up with innovative ways for transit media to serve the very best to its clientele, within the given budget. With the growing mediums, changing fashions and innovative styles of advertising, the evolution of these full service advertising agencies can be seen in day-to-day life. Every single day, a new and creative style of advertising is discovered, and added to the various departments of full service advertising agencies.
