DESCRIPTION
Sodium hydroxide, often referred to as caustic soda, is a highly caustic, alkaline chemical compound with the chemical formula NaOH. It is available in various forms, including flakes, pellets, and liquid solutions. Sodium hydroxide flakes are one of these forms. What is The Difference Between Caustic Soda Pearls and Caustic Soda Flakes?
CUSTIC SODA FLAKES (NaOH/ Sodium hydroxide) is one of the most basic alkaline raw materials in the chemical industry and is widely used in many fields. The main downstream industries include: aluminum oxide, printing and dyeing, chemical fiber, chemical industry, pulp and papermaking, water treatment, petroleum, military industry, light industry, pharmaceutical, lithium battery, metallurgy, electroplating, soap, purification of coal tar products, food processing, wood processing, mechanical industry, cleaning, and disinfection.

Chemical Formula: NaOH (Sodium Hydroxide)
Physical State: Sodium hydroxide flakes are solid and generally appear as dry, white, and crystalline flakes. They can vary in size, but they are typically thin and flat.
Solubility: Sodium hydroxide flakes are highly soluble in water, and when dissolved, they produce a strongly alkaline (basic) solution. This solution is commonly used in various industrial and laboratory applications.
Causticity: Sodium hydroxide is highly caustic and can cause severe burns upon contact with the skin. It is essential to handle it with care, and appropriate safety precautions, including the use of protective gear such as gloves and goggles, are necessary when working with it.
Chemical Reactivity: Sodium hydroxide is a strong base and can react vigorously with acids. It is also used in various chemical reactions and processes, such as saponification in soap making.
Density: The density of sodium hydroxide flakes can vary depending on their specific form and purity. However, it is generally dense, and a typical value is around 2.13 grams per cubic centimeter (g/cm³).
Melting Point: Sodium hydroxide flakes do not have a distinct melting point. Instead, they tend to deliquesce, which means they absorb moisture from the air and form a solution. This property can make them appear as if they are melting at high humidity levels.
Storage: It is important to store sodium hydroxide flakes in a cool, dry place away from moisture and incompatible materials. Containers should be tightly sealed to prevent absorption of moisture from the air.
Industrial and Laboratory Applications: Sodium hydroxide flakes are widely used in various industrial processes, including the production of chemicals, detergents, paper, textiles, and soaps. They are also used in water treatment to adjust the pH of water and remove impurities. In laboratory settings, sodium hydroxide is employed for chemical analysis, titration, and various chemical reactions.
Packaging: Our sodium hydroxide flakes are typically packaged in containers that protect them from moisture and air to maintain their quality and effectiveness.
In the chemical industry, sodium hydroxide is used to make sodium metal and electrolyze water. Sodium hydroxide or sodium carbonate is used in the production of many inorganic salts, especially in the preparation of some sodium salts (e.g. sodium tetraborate decahydrate, sodium silicate, sodium phosphate, sodium dichromate, sodium sulfite, etc.). Sodium hydroxide or sodium carbonate is also used in the synthesis of dyes, drugs and organic intermediates.
NaOH solution can be used for preparation of various cleaning agents, such as car washing liquid, bottle washing agent, cleanser essence, rust remover and disinfectant. It is mainly used for cleaning of bottles in wine industry, and surface treatment in ceramic and metal industry.
Sodium hydroxide is used in the following topics in water treatment: water purification; elimination of the hardness of water; adjustment of the pH value of water; neutralization of the wastewater; removal of heavy metal ions in water by precipitation; and regeneration of ion exchange resin, etc.
In sewage treatment plants, sodium hydroxide can reduce the hardness of water through neutralization reaction. In the industrial field, it is regenerating agent for ion exchange resin regeneration. Sodium hydroxide has strong alkalinity and relatively high solubility in water, so the use amount can be measured easily and it can be conveniently used in various fields of water treatment.
Stomach medicine: Its ingredients are aluminum hydroxide, magnesium hydroxide, sodium bicarbonate and a small amount of sodium hydroxide, and its main function is to neutralize gastric acid.
To dye cotton fabrics in the printing and dyeing industry, the covers on the surface of cotton fibers, such as wax, grease, pectin, etc. shall be removed, and the impurities can be removed by soaking and cooking with dilute alkaline solution at an appropriate temperature. In order to make the dye penetrate into the inner layer of the fiber during dyeing, the dye should be expanded and softened before dyeing. Short-time treatment with concentrated caustic soda solution can make the fiber molecules arranged in oriented manner and the mercerizing color of the fabrics can be increased. After the treatment, the fine fibers (velveteen) on the fiber surface can be corroded by caustic soda, the dyeing will be more uniform and there will be no patches of different depths. A large amount of caustic soda is needed in the cotton printing and dyeing industry.
Alkali cellulose can be obtained from cellulose after treatment by caustic soda. Then treat the alkali cellulose into cellulose xanthogenate with carbon disulfide, dissolve it in dilute alkali into viscose liquid, then spin and coagulate it to obtain viscose fiber. It is usually called artificial cotton, artificial wool and artificial silk in the market. Production of 1 ton of artificial wool consumes 1 ton of caustic soda.
Caustic soda flakes plays an important role in the papermaking industry. Because of its strong corrosiveness, it is used in the process of boiling and bleaching paper sheets. At the same time, the raw materials of papermaking are mainly wood or grass. These plants contain cellulose and quite a lot of non-cellulose (lignin, gum, etc.), and the fiber can be chemically treated. Use ferrous sulfate or alkaline solution to steam and boil the raw materials, and according to the characteristics that the dilute alkali cannot react with cellulose but can corrode and dissolve non-cellulose components, produce the pulp with cellulose as the main component. This kind of pulp fiber is long, the tensile force of the paper is strong.
