Caustic soda, also called sodium hydroxide, is a strong caustic alkali, generally white translucent sheet solid, soluble in water (heat release when dissolved in water) and forms an alkaline solution. It is deliquescent, easy to absorb water vapor and carbon dioxide in the air. Caustic soda in water treatment can be used as an alkaline cleaner, soluble in ethanol and glycerin, insoluble in propanol, ether. It also corrodes carbon and sodium at high temperatures. And it has a disproportionation reaction with chlorine, bromine, iodine, and other halogens. It forms salt and water when neutralizing with acids. Contact us online to can get a price list now.

What is Caustic Soda 99% Used for

Caustic soda uses in making soap, printing and dyeing, textile, papermaking, refined petroleum, metallurgy, and other chemical industries because of its strong alkalinity. In addition, the production of dyes, plastics, and preparation of borax, manganate, phosphate, etc. also requires the use of a large amount of caustic soda. 

Caustic soda is widely used as water treatment chemical. In wastewater treatment plants, sodium hydroxide can reduce the hardness of water through a neutralization reaction. In the industrial field, it is a regeneration agent for the regeneration of ion exchange resins. Sodium hydroxide is strongly alkaline and has relatively high solubility in water. Because sodium hydroxide has relatively high solubility in water, it is easy to measure the amount and can be conveniently used in various fields of water treatment.

Caustic soda has been used for traditional domestic purposes. To this day, the rare demand for soap, soap boxes and other kinds of washing products still accounts for about 15% of caustic soda. Making soap is the oldest and most widespread use of caustic soda. Ordinary soap is the sodium salt of higher fatty acids, which is generally made by saponification of oil under the action of slightly excessive caustic soda. In the making of soap, caustic soda is used to neutralize fatty acids.

It is mainly used for indigo dyes, quinone dyes. In the process of vat dyeing, it should be used first to reduce it to cryptochromes acid. After dyeing, oxidant should be used to oxidize it to the original insoluble state. Cotton fabric treated with caustic soda liquid can remove the wax, grease, starch and other substances covered in cotton fabric, and at the same time can increase the luster of the fabric, so that the dyeing is more uniform.

In the textile industry, cotton and linen fabrics are treated with caustic soda solutions to improve fiber properties. Artificial fiber such as rayon, wool, rayon, mostly viscose fiber, they are cellulose (such as pulp), caustic soda, carbon disulfide as raw materials, made viscose liquid, the spinneret, condensation and made.

The raw materials of papermaking are wood or grass plants. In addition to cellulose, these plants also contain a considerable amount of non-cellulose (such as lignin, gum, etc.). Caustic soda pearls/flakes are used to remove lignin. Only by removing lignin from wood can fiber be obtained. Adding it can dissolve and separate the non-cellulose components, thus making pulp with cellulose as the main component.

Caustic soda pearls/flakes are also used for refined petroleum. In order to remove the colloid in petroleum fractions, concentrated sulfuric acid is usually added to the petroleum fractions to make the colloid become acid residue and precipitate out. After pickling, the oil also contains phenol, naphthenic acid, and other acidic magazines and excess sulfuric acid, must be washed with caustic soda solution, and then washed by water, in order to get refined petroleum products.

In the metallurgical industry, it is often necessary to convert the active components of ore into soluble sodium salts in order to remove the insoluble impurities therein. Caustic soda is therefore often required. For example, it is used in the preparation of cryolite and the treatment of bauxite in the smelting of aluminum. And when smelting tungsten, it is also the first concentrate and caustic soda roasting into soluble sodium tungstate, and then through the process of acid evolution, dehydration, reduction and so on to make powdered tungsten.

Caustic soda flakes/pearls can be used for various cleaning agents. Such as car washing agent, bottle washing agent, detergent, rust remover, disinfectant configuration. Mainly used for cleaning wine bottles, ceramic metal industry surface treatment and so on. There are two main functions of caustic soda in ceramic manufacturing: First, it is used as a diluent in the ceramic firing process. Second, the ceramic surface will be scratched or rough after firing. After washing with a its solution, the ceramic surface will be smoother.
