Caustic soda flakes is an important chemical with wide applications in many industries which known as some other names like sodium hydroxide, lye, caustic and etc in different markets and with have various purities and types in two different shapes liquid and solid is supplying by BASEKIM company to all over the world.
Caustic with general chemical formula NaOH is an alkaline chemical and according to its high PH uses in many fields as PH controller or in drilling mud that it is just a part of this chemical usages. Sodium hydroxide up to 99% purity is supporting by our company in different types and specs and exporting to every spot on the world with the best quality and competitive price.
Sodium hydroxide is a highly caustic substance that is used to neutralize acids and make sodium salts. Sodium hydroxide physically is a white crystalline like snow, odorless and solid that absorbs moisture from the air. It is easily soluble in water when dissolved in water or neutralized with acid it liberates substantial heat, which may be sufficient to ignite combustible materials. Sodium hydroxide is very corrosive.
It is generally used as a solid or a 50% solution. Other common names include caustic soda flakes and lye. More than 95% production capacity of chlorine and approximately 100% of the production capacity of cadmium (sodium hydroxide) is based on the hydrolysis of salt water. In this process, a solution of sodium chloride (salt water) is decomposed electrically to elemental chlorine and a solution of sodium hydroxide and elemental hydrogen. a liquid production method using sodium chloride as a raw material is a multiprocessing process today, there are generally three commonly used methods to produce it.
Caustic soda in many fields has noticeable usages somehow that the range of it applications is from foodstuffs to chemical making.
Lye also is used for aluminum industries, pulping, sewage refinery, rubber bleaching and detergents, water purifying, making tiles, pharmaceutical, ceramics, artificial silks, color making, leather and textiles, cosmetics, glass making, gas and oil industry, batteries, neutralized acids, soft drinks, alcohol making, sugar making, oil industries, polymers, stick industries, disinfectants and lots of other industries which the needed it is producing by Basekim company and exporting to all over the world.
Paper pulping ,there are wide range of chemicals which use in paper industry in another way its tell paper chemicals .Chemical usage is not only for imparting properties to paper but to handle the water cycles in the process, conditioning of fabrics, cleaning of equipment and several other applications.
Preparing the pulp involves separating out the cellulose fibers from the plant material. Many plant materials are very tough and require boiling in sodium carbonate (soda ash) or caustic soda (lye) at ph 12-14 to accomplish.
It is a key component of the white liquor solution used to separate lignin from cellulose fibers in the sulfate process. It is added to increase the ph in the pulping process of fibers. The higher ph of the paper-fiber solution causes the fibers to smoothen and swell, which is important for the grinding process of the fibers.
It is also use in Kraft pulping process involves treatment of wood chips with a hot mixture of water, caustic soda , and sodium sulfide (Na2S), known as white liquor.
This product in the Kraft process or Sodium Hydroxide in soda pulping are used to break the lignin bonds of wood being processed into pulp for papermaking. Using recycled chemicals as makeup from other sources (spent caustics) aids in the reduction of the environmental impact of chemical pulping.
Detergent , Caustic soda is often used to manufacture cleaning products like soaps and detergents. The chemical formula for detergent is: C 18 H 29 NaO 3 S.
It is perfect for removing stains from clothing, upholstery, leather, carpeting and linens on your bed and in the bathroom. It quickly removes grease, paint, ink, blood, coffee and other food stains on your clothes.
It is the most commonly-used alkali, but if it is too expensive or not available, caustic potash can be used. Caustic soda produces a hard soap, whereas caustic potash makes a softer soap which is more soluble in water. In soap and detergent industry, it is used in saponification, the chemical process that converts vegetable oils into soap. It is used to manufacture anionic surfactants, a crucial component in most detergent and cleaning products.
The most important are sodium silicate (water glass), sodium carbonate (soda ash), sodium perborate, and various phosphates.
Chemical name and common name is washing soda, lime stone, soda lime, baking soda. It is an alkali and has several uses. As the name suggests washing soda is commonly used in detergents.
caustic cleaners, used for clean Bacteria, fungi, yeasts, viruses, and endotoxins . Caustic cleaners are used worldwide within detergent
This includes defoamers, surfactants, and rust inhibitors. A parts washer heats detergent and water in a closed cabinet, spraying them at pressure against dirty parts for degreasing applications. While parts washer detergents based on sodium hydroxide are among the most aggressive parts washer cleaning chemicals, they are also considered environmental improvements over the solvent-based cleaning methods.
Since it has water attraction and the humidity causes to reduce the quality of this matter, needed to has safe and moisture proof packing and according to this our company has the modern packing machines with ability to support various volume of the customer requests in multiple layer packing’s with strong standards and with different capacities for different markets and also with printing the privet logo on the bags as an option.

This type of bag has a width of 50 × 80 and is the best possible packaging for caustic soda, especially for export abroad. Corrosion and decay of the yarn along the way, which in turn causes the lid of the bag to open and the lump inside to clog due to contact with air or moisture.
This packaging model has been created only for easy transportation. In this model, some 25 kg bags of caustic soda are placed on a durable plastic or wooden pallet, and using different materials such as plastic next to each other hold them tight.
Planting industry and caustic soda , or in other words its chemical name, sodium hydroxide, is known as a corrosive substance that works especially well on organic materials such as soil, food, and hair. This substance can be dissolved in water, which is one of the reasons it works so well on clogged drains, and also NaOH is usually used to adjust the pH of the medium and to prepare the storage solution of growth regulators in plant tissue culture.
At planting industry caustic soda is uses to neutralize acidic environments, which explains its frequent use in the production of chemicals. Because sodium hydroxide is a very strong base, it is often used to absorb acidic secretions or gases that can be neutralized with a base. Caustic potash is usually a white solid that can dissolve in less than its own weight in water. It has universal applications in soaps and detergents, fertilizers and industrial operations.
The caustic soda can kill many invasive trees when applied directly to a cut stump. and also 96% of all pesticides are produced using chlorine.
Sodium hydroxide (NaOH), also called caustic soda or lemon, is a corrosive white crystalline solid that contains the cation Na + (sodium) and the anion OH – (hydroxide). It easily absorbs moisture until it dissolves.
The low salt index and high solubility of potassium hydroxide make it ideal for mixing liquid fertilizers. Potassium strengthens the root system of plants, which enhances disease resistance in plants, increases yield and overall quality of crops, prevents wilting and improves drought tolerance of crops.
Scientists can use sodium hydroxide to absorb carbon dioxide from the air so that plants do not use it in photosynthesis.
Sodium hydroxide is used to remove the skin of tomatoes, potatoes, and other fruits and vegetables for canning, and is also used as an ingredient in food preservatives to help prevent the growth of fungi and bacteria in food.
water treatment industry to raise the pH of water mainly used caustic soda. it does this by absorbing water and carbon dioxide, and is commonly an integral component of water treatment.
It is a white, alkaline, flakes and odorless packed in drums.Sodium hydroxide, or NaOH is a commonly used water treatment chemical that raises the pH of water by absorbing water and carbon dioxide, and also hydrochloric acid, hydrated lime, sulfuric acid, are chemicals that help make contaminants in wastewater stick together, so they will be easier to remove, the optimum dosage to reach the recommended pH of 12 is around 26 g of soda per litter of faecal sludge. The exact amount, however, de pends on the characteristics of blackwater or sludge. Its effect can be enhanced by ensuring complete mixing, a longer contact time and a higher dosage of caustic soda. The pH should be maintained above pH 12 for a minimum of 2 hours to ensure an adequate reduction of pathogens.
The Caustic Soda Treatment process should be undertaken as a batch process and can be used to treat both solid and liquid sludge. After treatment, pH decreases towards neutral usually within 24 hours. After neutralization, the supernatant can be pumped off and safely infiltrated into a Soak Pit . Care should be taken in areas with high a groundwater table as the supernatant still contains ni trogon and phosphorous which can pollute water bodies. The treated solid fraction at the bottom may be applied as a soil amendment or dried and used as cover for sanitary landfill om water.
pH value will increase and become much greater than 7 on adding it to water. Caustic soda is general name for NaOH which is a strong base. So, when we add caustic soda to water, it will make the water basic in nature. A basic solution has a pH greater than 7.
The reaction will be Exothermic, where heat will be released. Sodium hydroxide is considered a strong base and as such is able to completely and fully disassociate in aqueous solution.
It is used primarily to increase and control pH in water-based fluids. Is a source of hydroxyl ion to increase and control ph.
Regular treatment with half strength mix (250g Caustic Soda to 6 litters of water) will prevent further blockages. Cleaning & sanitizing (dustbins, kennels, stables, driveways etc.) Add 1-2 tablespoons of it per 5 litters of water
This treatment method is used if the water is acidic (low PH). Soda ash (sodium carbonate) and sodium hydroxide raise the pH of the water to near neutral when injected into a water system. Unlike neutralizing filters, they do not cause hardness problems in treated water.
Injection systems are point-of-entry systems. A corrosion-resistant chemical feed pump injects soda ash or sodium hydroxide solution into the water to raise the ph. The solution should be fed directly into the well to protect the good casing and pump from corrosion.
If the water needs to be disinfected as well as neutralized, dual treatment is possible within the injection system by adding a chlorine solution (sodium hypochlorite) along with the neutralizing chemical. Injection systems can treat water with a pH as low as 4.
In industrial Cleaning ,Sodium hydroxide is one of the strongest bases, It is both a degreaser and a cleanser. It dissolves grease, oil, and protein-based deposits, producing a water solution that you can wash off.
Surfactants can be added to the sodium hydroxide solution to stabilize the dissolved material, thereby preventing re-deposition. Prevent.
Sodium hydroxide soaking solution is used as a strong degreaser on stainless steel and glass bakeware. It is also a common ingredient in stove cleaners.
In industrial production, it is common to save time by adding a salt such as sodium chloride to the sodium hydroxide solution to combine cleaning and disinfection.
Sodium hydroxide is often used as an industrial cleaning agent, often referred to as a “beneficial”. It is added to water, heated, and then used to clean process equipment, storage tanks, etc. It can dissolve fat, oil, grease and protein-based deposits
Simple chemicals are also widely used in the production of industrial cleaners. These include: soda, sodium hypochlorite and hydrochloric acid and Caustic soda.
Sodium hydroxide is widely accepted for cleaning, disinfection and storage of chromatography media and systems and used for resins.
For resins, the most important cleaning agent is sodium hydroxide. Some reports indicate that heated sodium hydroxide is an excellent cleaning agent. Even without heating, high concentrations of sodium hydroxide require evaluation of facilities and equipment and the use of safety equipment to protect workers.
During limited inspections, manufacturers of biopharmaceuticals and biological products typically focus on verifying the cleaning and disinfection of chromatographic resins and multipurpose purification systems. Chromatography resins must either be discarded or cleaned sufficiently to ensure reproducibility in subsequent cycles.
Over the years, various cleaning agents have been proposed. After evaluating a new cleaning agent for a resin, make sure it is also compatible with system components.
Nucleic acids can bind strongly to the anion exchangers of chromatography equipment. 1 M sodium hydroxide and 3 M sodium chloride, with a total contact time of one hour, efficiently removed labeled calf thymus DNA from a weak anion exchanger.
Aluminum , is the largest caustic soda application segment in the chlor-alkali market. Caustic soda is used in the process of extracting alumina from bauxite ore. It dissolves bauxite ore, which is the raw material for it production. In this process, pure alumina is separated from bauxite ore. The collected alumina is further subjected to calcination.
Therefore, when alumina , which is an amphoteric metal, reacts with caustic soda, sodium aluminate is formed and hydrogen gas is evolved as a result.
The reaction is as follows:
Aluminum + 2 Na O H Caustic soda + 2H2O → 2Na A lO2 Sodium met aluminite + 3H2 ↑ Hydrogen gas
This reaction is very exothermic.
The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminum oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of alumina, contains only 30-60% aluminum oxide (Al203), the rest being a mixture of silica, various iron oxides, and titanium dioxide. The alumina oxide must be further purified before it can be refined into alumina metal. For this process used caustic soda, It dissolves bauxite ore.
Chlor-alkali products include chlorine, caustic soda, and soda ash. The main technologies used in the chlor-alkali process are membrane cell, diaphragm cell and mercury cell to produce chlorine. The chlorine produced from the electrolysis of an aqueous solution of sodium chloride (common salt or Na Cl). Soda ash is produced from the mining and refining of Tron ore (natural) and also through the Solvay process (synthetic). The chlor-alkali process is energy intensive.
Drilling fluids ,Caustic Soda provides many solutions to aid in drilling and fractions.
Soda ash is used to raise the pH of make-up water for bentonite and polymer drilling by precipitating soluble calcium.
It helps to solubilize acidic compounds, it assists in reducing the corrosively of water-based drilling , it increases the hydration rate of dispersed clays, and in lime-based drilling muds, it reduced the solubility of lime.
Using caustic soda will increase the performance of bentonite and polymer drilling industry . Soda ash should be added slowly through a hopper or chemical barrel.
Soda is used to maintain or increase pH. Increasing pH with sodium hydroxide precipitates magnesium (Mg2+) and suppresses calcium (Ca2+) in high hardness waters such as seawater, reduces corrosion, and neutralizes acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S).
Water can have a primary influence on the success of any type of drilling. The efficiency and success of drilling projects can be easily determined by the water used. importance of water in drilling industry is clear , since water makes up 95 to 99 percent of the drilling fluid using. Importantly, the pH of drilling mud is one of the key parameters to determine its performance. As such, it performs better within pH range of 8.0 to 10.5 for water base mud.
Paint remover ,Caustic soda is well known for its properties for stripping paint. It allows to remove the layers of paint or varnish as quickly as possible and with the least fatigue. We can use it as a solvent-based paint stripper. Caustic soda is an excellent stripper for wood and metals. Using soda lye reduces the risk of surface damage that may occur using other methods.
Paint remover , typically sodium hydroxide (also known as lye or caustic soda), work by breaking down the chemical bonds of the paint, usually by hydrolysis of the chain bonds of the polymers forming the paint. A solution of sodium hydroxide in water was traditionally used as the most common paint stripper. However, it seems that an effective and cheap alternative to the mechanical removal of paints and coatings from the surface.
The most common utilize of paint stripper along with water is Caustic soda and Trisodium phosphate hydrolyzed and decompose the paints and that can be removed.
Caustic soda, also known as sodium hydroxide (NaOH), is sometimes used in gold mining to extract gold from ore. The process, known as “cyanide leaching,” involves mixing finely ground ore with a cyanide solution and then adding caustic soda to the solution to raise its pH level. The increased pH level causes the cyanide to dissociate into its ionic form, which can then react with the gold to form a soluble complex that can be separated from the ore.
The use of cyanide leaching with caustic soda is a common method for extracting gold from low-grade ores, as it is relatively inexpensive and efficient. However, it is also a highly toxic process that poses significant environmental risks if not managed properly. The cyanide solution and other chemicals used in the process must be contained and properly disposed of to prevent contamination of water sources and other environmental damage.
In recent years, there has been increasing interest in alternative gold extraction methods that do not rely on cyanide or other toxic chemicals, such as thiosulfate leaching or bioleaching. These methods are still being developed and tested, but they offer the potential for a more environmentally sustainable and socially responsible approach to gold mining.
Caustic soda is the most popular preparation to remove paint is. To prepare it, measure the right amount of caustic soda and gradually pour water into it, while stirring the contents in the container vigorously.
For paint stripping need to Add 250g Caustic Soda to 1 litter of cold water. Apply carefully with an old paint brush.
