Sodium Hypochlorite and its Many Uses



Sodium hypochlorite comes handy in many different ways, which is why it is used so often as a common ingredient in different kinds of chemical products. Sodium hypochlorite is particularly useful as a disinfectant and is hence present in a wide array of disinfectants, sanitizers and chlorinated cleaners. Some of these are used as no rinse sanitizers, as sanitizing concentrates and virus destroyers. One of the uses of sodium hypochlorite is as a part of graffiti removal products. Liquid bleach for example, comprises of 4% sodium hypochlorite and is extremely effective amongst graffiti removal products. Stain removers with sodium hypochlorite can come really handy when you want to clean up exterior faces of walls, whether it is houses or large institutions.

It isn’t always possible to prevent people from making graffiti on the walls, especially when you love them clean. However, you can use a variety of graffiti removal products to bring them back to the original. Sodium hypochlorite because of its bleaching properties proves to be an extremely effective solution to such problems. It can be used for stain removal just as effectively as it is used for deodorizing or as a disinfectant. The de-staining properties of sodium hypochlorite work against crockery and silverware stains and stains that are caused by tea tannins and fluorosis. Mold stains and dental stains can also be effectively removed by using it.

One of the biggest advantages offered by sodium hypochlorite is that it doesn’t have too many side effects. In other words, it is not one of those chemicals that offers solution to one problem and creates four new problems for you. It has been popular for a while as a disinfecting agent for drinking water and is used for water systems too. Moreover, this is a great alternative to using chlorine gas for disinfecting water, considering that there has been a huge outcry over the harmful byproducts created such as chloroform. Moreover, it is also easy to handle and transport this compound making it easily accessible and quite cheap.

One of the important properties of bleaching agents is their strong oxidizing quality. That is why sodium hypochlorite is actually effective when used in graffiti removal products. It has been certified that solutions that have more than 40% of the compound are dangerous and can cause lasting damage in the form of eye problems and burnt skin. However, it is used in minimal quantities in bleaching solutions and bleaching products. Pollution abatement systems also use it in small quantities. There are degreaser sanitizers and mild natural acid cleaners anddisinfectants which use the compound as well. There are acid sterilizers and toilet cleaners that make use of it as well. Graffiti removal products before being purchased should be checked for certification for safe usage. There are specialist agencies with trained staff, which have the right protection equipment before using graffiti removal products on walls, pillars and glass. There are entire industries dedicated to producing a comprehensive range of safe graffiti eliminators.

Aluminum Cleaner and sodium Hypochlorite

An Aluminum cleaner is generally used to remove oxidation from aluminum surfaces. There are several different varieties of aluminum cleaner. The most popular and common varieties of are either silicated or non silicated cleaners. Both cleaners offer different advantages, and both varieties offer non-etch cleaning, which is essential when trying to avoid destroying the surface of material.

One common aluminum cleaner is silicated, non-etch, soak-cleaning varieties. This silicated aluminum cleaner is a granulated blend of surface active agents and alkaline materials that, after being dissolved in water, create highly buffered cleaning surfaces that do not wear away or etch at aluminum surfaces. Non-silicated aluminum cleaners are also commonly used. These cleaners are non-dusting and off white in color, and are powdered products that operate mainly to alkaline soak-clean aluminum before it gets etched, plated or anodized. This is a quickly dissolving aluminum cleaner that is a free-rinsing solution.

One of the main benefits of non-silicated Aluminum Cleaner is that they do not dull or harm the surface of aluminum varieties that are brighter in appearance. This is because they do not contain either silicates or chromates. Aluminum surfaces are safe with the use of these non-silicated cleaners. Silicated aluminum cleaners are beneficial because they clean dirt away more rapidly than other types of aluminum cleaner. Both silicated and non-silicated aluminum cleaners have excellent water-softening properties, which enable the distinct blend of surfectants inside of the cleaner to give off good detergency and emulsification when in the presence of hard water. These qualities are vital for complete soil elimination and fast cleaning of aluminum.

With silicated and non-silicated aluminum cleaners, the necessary cleaning time varies and depends on the variety and degree of the dirt and soil that is present on the surface of the material. The temperature and the concentration of the silicated aluminum cleaner also factors into the time that will be necessary in order to properly clean the surface.

Sodium Hypochlorite (NaOCl) is a compound that can be effectively used for water purification. It is used on a large scale for surface purification, bleaching, odor removal and water disinfection. Sodium hypochlorite is used on a large scale. For example in agriculture, chemical industries, paint- and lime industries, food industries, glass industries, paper industries, pharmaceutical industries, synthetics industries and waste disposal industries. In the textile industry sodium hypochlorite is used to bleach textile. It is sometimes added to industrial waste water. This is done to reduce odors. Hypochlorite neutralizes sulphur hydrogen gas (SH) and ammonia (NH3). It is also used to detoxify cyanide baths in metal industries. Hypochlorite can be used to prevent algae and shellfish growth in cooling towers. In water treatment, hypochlorite is used to disinfect water. In households, hypochlorite is used frequently for the purification and disinfection of the house.

There is no threshold value for to sodium hypochlorite exposure. Various health effects occur after exposure to sodium hypochlorite. People are exposed to sodium hypochlorite by inhalation of aerosols. This causes coughing and a sore throat. After swallowing it, the effects are stomach ache, a burning sensation, coughing, diarrhea, a sore throat and vomiting. Sodium hypochlorite on skin or eyes causes redness and pain. After prolonged exposure, the skin can become sensitive. Sodium hypochlorite is poisonous for water organisms. It is mutagenic and very toxic when it comes in contact with ammonium salts.
