Caustic soda
Caustic soda (sodium hydroxide) is a versatile alkali. Its main uses are in the manufacture of
pulp and paper, alumina, soap and detergents, petroleum products and chemical production.
Other applications include water treatment, food, textiles, metal processing,
mining, glass making and others.
Application of Caustic Soda in Textile Industry
In the textile industry, caustic soda is used for dyeing synthetic fibers such as polyester and
nylon, as well as flax processing.
Application of Caustic Soda in Food Production
Peach soda is used to produce a type of salt wood to make crumbs, to process and process olives,
to peel tomatoes and other fruits, to make canned food, and to peel potatoes. Other benefits of
baking soda include preventing the growth of food mold and bacteria and thus helping to prevent
them from spoiling.
Other Applications of Caustic Soda in the Food Industry Include the Followings:
Milk industry
Chocolate production
Production of packaging
Noodle production
Beverage production
Sugar production
Caramel production
Washing fruits and vegetables
Canning industry
Oil refining
Application of Caustic Soda in Pharmacy and Medicine
It is interesting to know that caustic soda is used to produce many drugs such as aspirin,
painkillers, anticoagulants, arterial anticoagulants, and more.
Application of Caustic Soda in Aluminum Extraction
Caustic soda is used as an alkaline compound for plating aluminum parts as well as for
dissolving Bauxite ore and thus precipitating aluminum oxide or alumina.
Application of Caustic Soda in Paper Industry
The most common use and application of caustic soda is in the cellulose or paper industries. It is
used in processes such as pulp making, pulp bleaching, water treatment and ink removal from
recycled paper.
Other uses of caustic soda in the paper industry are include the followings:
Increasing the pH of the paper fiber fermentation process
Separation of cellulose fibers from lignin
Production of pulp
Decomposition of wood
Smooth, swell and polish paper fibers
Improve the quality of milled paper fibers
Bleaching of brown fibers in the cooking process
Application of caustic soda in the production of cellophane and rayon or rayon
Caustic soda lye is used to increase the gloss, luster and strength of cellulose. This processed
cellulose is used to produce viscose, which is used in the production of cellophane and silk
synthetic fibers. The production of these fibers in two stages of the viscous process requires the
use of caustic soda.
Application of Flake Soda in the Production of Soap and Detergent
Production of detergents is another industry which caustic soda flake is very important in it. In
this industry, sodium hydroxide is used in a process in which fats, vegetable oils and foundations
are converted into soap. On the other hand, flaxseed is a very important compound for the
production of essential substances called anionic surfactants in the preparation of detergents.
Application of Caustic Soda in the Production of Bleach
Bleaching agents, which are made from caustic soda, are mostly used in industry and are used to
control mold and fungus and to remove grease.
Application of Caustic Soda in Glass Industry
Soda ash can be used as a substitute for soda ash in many industries, including glassmaking,
phosphate production and silicate.
Application of Caustic Soda in Chemical Processes
Caustic soda is used as a raw material in the production of many chemical products, including
the following:
Production of plastic materials
Adhesive production
Solvent production
Production of herbicides
Production of paints and inks
Production of coating materials
Application of Caustic Soda in the Leather Industry
Sodium hydroxide and sodium sulfide are used on the inner surface of sheep and lambs in leather
factories. This compound penetrates the skin and attacks the roots or hair follicles. In this way,
wool and hair are easily separated from the skin.
Application of Caustic Soda in Petrochemical and Refinery
Caustic soda or sodium hydroxide is used in oil exploration, production and processing of natural
gas and oil.
Application of Caustic Soda in the Production of Renewable Fuels and Energy
Caustic soda is used in the production of fuel cells as well as in the production of epoxy resins
used in the production of wind turbines. On the other hand, caustic soda is used to adjust the pH
to produce sodium methyl and finally to produce biodiesel and bioethanol.
Application of Caustic Soda in Water and Wastewater Treatment
As you know, bleach or sodium hypochlorite is a kind of disinfectant and the benefit of flaxseed
is used in its production. On the other hand, caustic soda is also used to help remove heavy
metals and control the acidity of water in the treatment plant and water and sewage system.
Other industries in which caustic soda is used include the followings:
Ceramic industry
Alcohol industry
The automotive industry
Neutralize the battery industry acid
Washing fuel and oil tankers
Rubber recycling industry
metal plating
Washing tanks and pipes
Drilling industry
Starch production
Cartoning industry
Degreasing and degreasing industry
In the laboratory and to determine the concentration of various acids
Cosmetics industry
Applications of caustic soda for home washing
Caustic soda is also used in home and industry for washing. Before starting work, wear safety
equipment such as masks, gloves and goggles to avoid endangering your health. The method of
washing with sodium hydroxide is as follows:
.
Application of Flake Soda in the Production of Soap and Detergent
Production of detergents is another industry which caustic soda flake is very important in it. In
this industry, sodium hydroxide is used in a process in which fats, vegetable oils and foundations
are converted into soap. On the other hand, flaxseed is a very important compound for the
production of essential substances called anionic surfactants in the preparation of detergents.
Washing the sink pipes:
Pour 1 kg of flake soda in the sink and then open the faucet.
Caustic soda reacts quickly with water and rinses pipes well as they pass through.
• Washing the kitchen hood filter:
To remove the grease from the kitchen hood filter,
you can pour some caustic soda in a bowl of water and then put the hood filter in this
mixture. caustic soda is a strong
