8. In the chemical sector, caustic soda is used to make metal sodium and also electrolyzed water. The manufacturing of numerous not natural salts, specifically the preparation of some salt salts (such as borax, sodium silicate, sodium phosphate, salt dichromate, salt sulfite, and so on) needs caustic soda or soda ash. Caustic soda or soda ash are likewise made use of in the synthesis of dyes, pharmaceuticals as well as organic intermediates.
9. Prep work of alumina The NaOH option is heated to liquify the alumina in the bauxite to get a sodium aluminate option. After the solution is separated from the residue (red mud), the temperature is lowered, as well as light weight aluminum hydroxide is included as crystal seed. Alumina completed item is obtained. The service after precipitation of aluminum hydroxide is called mom alcohol, which is recycled after evaporation and concentration. As a result of the different crystal structures of gibbsite, boehmite and diaspore, their solub
ility in caustic soda remedy is very various, so different dissolution conditions need to be supplied, mostly various dissolution temperatures. The gibbsite-type bauxite can be liquified at 125-140 ℃, and also the diaspore-type bauxite must be dissolved at 240-260 ℃ as well as lime (3-7%) is added.
10. There are 2 features of ceramic caustic soda in ceramic production. First, in the shooting process of ceramics, caustic soda is made use of as a diluent. Second, the surface of the terminated ceramic will be scraped or very rough, and it needs to be cleaned up with caustic soda service. After that, make the ceramic surface area smoother.
11. Sanitation: Pure Salt Hydroxide denatures the healthy protein of the infection. These are generally used for cleaning and disinfection of containers in the wine sector and also various other markets.
12. Along with wastewater: solid salt oxide changes the pH worth, sewage therapy, and also recycling of resources.
13. Chemical preparations, industrial ingredients. Caustic soda is mainly made use of in the pharmaceutical market to alkalize solutions or change the pH value of liquid medicines.
14. Electroplating, smelting tungsten. Caustic soda is used as an electroplating service in equipment electroplating as well as serves as a conductor!
15. Manufacture silk Pure Sodium Hydroxide manufactures rayon.
16. Sun tanning: a process for recycling waste ash liquor from sun tanning. On the one hand, in between the two actions of taking in sodium sulfide liquid solution in the existing development procedure as well as adding lime powder for saturating, boost making use of 30% tare 0.3-0.5%. The %Pure Sodium Hydroxide service treatment step makes the skin fiber fully increase to fulfill the procedure requirements and enhance the quality of semi-finished products.
17. Tanning: used as an alkaline tool in this product, as well as additionally as a neutralizing representative. Add the suggested amount of water right into the response pot, then heat it approximately 90 ° C by heating it with heavy steam, include polyvinyl alcohol while mixing, and after the polyvinyl alcohol is completely dissolved, then cool down to 80 ° C for the glue remedy. Add hydrochloric acid in a drip method, proceed mixing for 20-30 minutes, add the formula quantity of formalin. Keep the temperature at 78-80 ° C, let it respond for 40-50 mins, include the ready 10% Pure Salt Hydroxide liquid service for neutralization, as well as cool down to 60 ~ 70 ℃, add the formula quantity of urea for amination therapy, as well as filter the glue via a gauze for use.
18. Pure Salt Hydroxide makes phosphate, produces manganate.
19. Regrowth of old rubber.
20. Cleaning agent chemical market is utilized to make formic acid, oxalic acid, borax, phenol, sodium cyanide and also soap, artificial fatty acid, synthetic detergent, and so on
21. Fabric printing and dyeing industry Pure Salt Hydroxide is made use of as cotton desizing agent, searching representative, mercerizing representative as well as solvent for barrel dye and Haichang blue color.
22. Smelting industry Pure Salt Hydroxide is utilized to make light weight aluminum hydroxide, alumina and metal surface treatment agent.
23. Tool Sector Pure Salt Hydroxide is made use of as acid neutralizer, decolorizer and deodorizer. Glue industry is made use of as starch gelatinizer and also neutralizer. It can be utilized as peeling off agent, decolorizing representative and deodorizing agent for citrus and also peaches.
24. Flake antacids can likewise be utilized in the manufacture of chemicals.
