Use 
Product use
1 for the production of cellulose pulp and papermaking;
2 used in soap, synthetic detergent, synthetic fatty acid production and animal and vegetable oils and fats refining.
3 textile printing and dyeing industry as cotton desizing agent, scouring agent and mercerizing agent.
4 the chemical industry for the production of borax, sodium cyanide, phenol, oxalic acid, etc..
5 petroleum industry is used to refine petroleum products, and is used in oil field drilling mud. Also used in the production of aluminum oxide, metal zinc and metal copper surface treatment, as well as glass, enamel, leather, medicine, dyes and pesticides.
6 food grade products used in the food industry as a acid neutralizing agent, can be used as a citrus, peach, etc., can also be used as empty bottles, empty cans and other containers of detergent, as well as bleaching agent, deodorant agent.
7 can also be used as a basic desiccant. Caustic soda is widely used in the national economy, and many industrial sectors need caustic soda. Most of the use of the Department of caustic soda is the manufacture of chemicals, followed by papermaking, aluminum, tungsten, artificial silk, artificial cotton and soap manufacturing. Also in the production of dyes, plastics, pharmaceutical and organic intermediates, the regeneration of old rubber, metal sodium, water electrolysis and the production of inorganic salts, preparation of borax, salt, manganese salt, phosphate, also want to use a lot of caustic soda.
Toxicity protection
Has extremely strong corrosive, its solution or dust splashed on the skin, in particular, splashing into the mucosa, can produce a soft callus, and can penetrate deep tissue. Scar after burn. Splashing into the eye, not only damage the cornea, but also make the eye deep tissue damage. Such as accidentally splashed into the skin immediately with water washing for 10 minutes; such as splash Ruyan should be immediately with clean water or saline rinse for 15 minutes, then 2% novo  caine. Severe cases of speed to hospital treatment. The maximum allowable concentration of caustic soda dust in the air is 0.5mg/m3. Operating personnel must wear gowns, masks, protective glasses, rubber gloves, rubber apron, rubber boots etc. PPE. Should be coated with a neutral and hydrophobic ointment on the skin. Production workshop should be well ventilated.
Packing&Storeage
Protopine generally use 25kg three layers of plastic woven bag, the inner layer and the outer layer is a plastic woven bag, the middle layer is a plastic lining bag. Caustic soda is the common dangerous chemicals classification and labels (GB 13690-92), designated as the 8.2 alkaline corrosion products, belonging to the eight levels of dangerous goods, the IMDG Code: 1823. Should be stored in dry warehouse ventilation, or the goods shed. Packaging containers to be complete, sealed. Not to be mixed with flammable materials and acids. The transport process should pay attention to moisture and rain. Fire, water, sand and all kinds of fire extinguishers, but fire personnel should pay attention to the corrosive water into the caustic soda.
The physical and chemical properties of pure products are colorless and transparent crystal, relative density of 2.130. Melting point 318.4. Boiling point 1390. Commercially available caustic soda has two kinds: solid and liquid: pure solid caustic soda is white, there are pieces of equipment, sheet, rod, granular, brittle; pure liquid caustic soda is colorless transparent liquid. Solid caustic soda has a strong moisture absorption. Soluble in water, dissolved exothermic, aqueous alkaline, creamy feel; soluble in ethanol and glycerol; insoluble in acetone, ether. Corrosive is extremely strong, to the fiber, the skin, the glass, the ceramics and so on has the corrosion function. And the metal aluminum and zinc, non - metallic boron and silicon and other reactions to release hydrogen and chlorine, bromine, iodine and other halogen halogen reaction; and acid from the neutralization effect and the formation of salt and water.
Save the solid sodium hydroxide to the attention of the seal, to prevent exposure to absorb the moisture in the air and carbon dioxide or deliquescence. When the glass bottle flakes or other forms of sodium hydroxide, glass is not available to plug should be replaced with rubber plugs, because NaOH will and glass silica reaction of sodium silicate in cork and bottle bonding is not easy to open.

Packing: 25 kgs/bag, 25 MT in one container without pellet
