9 Facts You Need To Know About Bleach
Bleach is a generic name for chemical products that are domestically or industrially used for the removal of color from a fiber or fabric or to remove or clean stains through the process known as bleaching. It is most times referred to as sodium hypochlorite solution, also known as liquid bleach.
Some bleaches have bactericidal properties, which makes them useful for sterilizing and disinfecting. They are used in the sanitation of swimming pools to control viruses, bacteria, and algae, and also in places that need sterilization. They are also applied for use in industries, majorly for bleaching wood pulp. There are also several minor uses like killing weeds, removing mildew, and increasing cut flowers' longevity.
Chemical Formula Of Bleach
The main component of bleach is Sodium Hypochlorite, which is also referred to as bleach. The chemical formula of bleach is NaCIO. It consists of one chlorine atom, one sodium atom, and one oxygen atom.
Chemicals in Bleach
Bleach is usually made up of several chemicals. The main component of bleach is sodium hypochlorite. It is mixed with small amounts of hydrogen peroxide, calcium Hypochlorite, and sodium hydroxide.
Acidic or Alkaline?
Bleach is a chemical used mainly for whitening fabrics and other materials. Bleach can be either alkali or acidic. The most common type of bleach used is alkaline sodium hypochlorite.
Manufacturing Of Bleach
The raw materials used in manufacturing bleach are caustic soda, chlorine, and water. Caustic soda and chlorine are manufactured by putting direct current electricity through a solution of sodium chloride salt in electrolysis. Sodium chloride is found in underground wells or mines. The salt is then dissolved in hot water to form a solution of salt, which is treated for any form of impurities, then reacted in the electrolytic cell. Herein are the process used in the manufacturing of bleach;
● Manufacturing Process
Several steps are involved in the manufacture of bleach. All of these steps are carried out at a manufacturing factory.
● Preparing the Needed Components
The caustic soda used in making bleach is normally at a concentration of 50%. This concentration is then diluted with water to reduce the concentration to 25% solution. When the caustic soda has been diluted, heat is created, and the caustic soda has to be cooled before proceeding.
The chlorine gas is also made available and kept in a properly sealed environment to avoid release into the environment which can be hazardous.
● Chemical Reaction
The caustic soda and chlorine are then mixed to make sodium hypochlorite bleach. To make bleach, chlorine gas is passed through the caustic soda solution. The action of caustic soda and chlorine is immediate.
● Cooling and Purification
The bleach solution then needs to be cooled to prevent decomposition. The cooled bleach is then filtered to remove any form of impurities that cause discoloration or decomposition.
Daily Uses To Clean
Bleach is also well known for its destaining capabilities. They can be used in the removal of mold stains, crockery stains, and dental stains. It can also be used as a surface cleaner and for the removal of hard stains from clothes.
Bleach due to hydrolysis and oxidation has caustic, cleaning, deodorizing, and bleaching effects. Bleach makes dirt non-volatile and water soluble which also aids in the reduction and removal of foul smell and odor.
Textile Industry Uses
Bleach is used in the textile industry for the removal of natural dyes and pigments that are present in the fibers and to give them a type of coloration. Its high reactivity makes its operating conditions softer than that of hydrogen peroxide. Otherwise, cellulose fiber damage is probable.
After bleaching, an anti-chlorine treatment is carried out to remove the hypochlorite completely and to decompose the chloramines that were produced during the bleaching process. The bleaching process can be carried out in batches, continuous or semi-continuous mode. Sodium Hypochlorite bleach and hydrogen peroxide can also be combined in bleaching textiles.
Sodium Hypochlorite bleach is usually used for knitted fabrics and yarns when a high level of whiteness is needed for materials that'll remain white, or when a white background is needed.
Bleach In Hair
Hair bleaching is the process of lightening the color of the hair, mainly for cosmetics through the use of bleach. Hair bleaching can be carried out alone, combined with a toner, or as a means of hair coloring. Bleach removes hair pigment from the hair shafts through the oxidation process. Basically, the process of hair bleaching always involves bleach.
Bleach Storage And Packaging
Bleach was originally first packaged in steel containers, then later on in glass containers. In 1960, they started the use of plastic jugs, which were lighter, non-breakable, and cheaper alternatives. The plastic jugs also didn't allow the penetration of ultraviolet rays,thereby increasing the bleach's effectiveness and stability. However, plastic containers are now an environmental concern due to the decomposition time.
Several companies are now reducing the amount of plastic used in packaging or they've started the use of recyclable plastic. Bleach should be stored in a cool place and away from reach because it can be harmful to both children and animals.
