Industrial Flakes Sodium Hydroxide Caustic Soda Flakes

Short Description:

Caustic Soda Flake also known as sodium hydroxide flakes. Flake mass is an odorless, white crystalline solid with a density of 2.13 g/mL, and melting point of 318°C. It`s whitecolor, very hygroscopic, also very soluble in water and alcohol. The formula is NaOH.A strong caustic alkali, generally in flake or granular form, readily soluble in water (exothermic when soluble in water) and forming an alkaline solution.NaOH is one of the essential chemicals in chemical laboratories and one of the common chemicals.

Product Description

● CasNo.: 1310-73-2

● Synonyms: Sodium Hydroxide

Caustic soda flakes are white translucent solid crystals. These waxy white crystals are odourless. The crystals are soluble in water and glycerol. This is an alkali, which is a combination of sodium cations and hydroxide anions (NaOH).

Chemical application and strengths：
• Caustic soda pearls or Sodium Hydroxide is one of the important inorganic materials for various industries all over the world. The major demand for caustic soda is evident in the paper industry for the pulping and bleaching process. Caustic soda is also a crucial raw material in aluminum production for dissolving bauxite ore.

• Caustic soda also finds many uses in the applications for degreasing and treatment of packaging in the food industry. The use of caustic soda is also prominent in chemical processing as a basic feedstock for various downstream products like plastics, solvents, etc.

• Caustic soda pearls also help in engendering the saponification of vegetable oils and fats required for manufacturing soaps. Caustic soda also finds applications In the textile industry for chemical processing of cotton. Most important of all. caustic soda is significantly important for the natural gas industry, where it helps In the production and processing of petroleum products.

• Caustic soda is also Important for elution stripping of gold that is adsorbed onto activated carbon. The mixture of caustic soda and cyanide interacts with carbon for extracting gold from the carbon. Special conditions of temperature , pH, and the flow rate of elution are highly important to the effectiveness of caustic soda In elution stripping.

• Caustic soda also finds small-scale applications such as paint stripping, chemical analysis, and aluminum etching. Furthermore, caustic soda is also used in various domestic products such as drain cleaners, oven cleaners, and other home-cleaning products.

Application

1. Caustic Soda Flakes Cas No: 1310-73-2

Sodium hydroxide is widely used. The sector that uses sodium hydroxide most is the manufacturing of chemicals, followed by paper making, aluminum smelting, tungsten smelting, rayon, rayon and soap manufacturing. In addition, in the production of dyes, plastics, pharmaceuticals and organic intermediates, the regeneration of old rubber, the electrolysis of metal sodium and water, and the production of inorganic salts, the production of borax, chromate, manganate, phosphate, etc., also requires the use of a large amount of caustic soda. At the same time, sodium hydroxide is one of the important raw materials for producing polycarbonate, super absorbent polymer, zeolite, epoxy resin, sodium phosphate, sodium sulfite and a large amount of sodium salt. In the overview of sodium hydroxide, we mentioned that sodium hydroxide is widely used in chemical industry, metallurgy, paper making, petroleum, textile, food and even cosmetics cream.

2. Process method:

Using in technology of pot method to produce caustic soda which could increase the content of NaCl in the caustic soda flakes.

3. Property:

Sodium hydroxide has strong alkalinity and strong hygroscopicity. It is easily soluble in water and exothermic when dissolved. The aqueous solution is alkaline and has a slippery feel; it is extremely corrosive and corrosive to fibers, skin, glass, ceramics, etc. It reacts with metallic aluminum and zinc, non-metallic boron and silicon to release hydrogen; reacts with halogens such as chlorine, bromine, iodine, etc.; disproportionates; reacts with acids to neutralize salt and water.

4. Storage:

Sodium hydroxide should be stored in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The storage temperature does not exceed 35℃, and the relative humidity does not exceed 80%. The packaging must be sealed and protected from moisture. It should be stored separately from easily (combustible) combustibles, acids, etc., and avoid mixed storage. The storage area should be equipped with suitable materials to contain the leakage
