CAUSTIC SODA
Caustic soda yog lub npe nrov rau sodium hydroxide, cov khoom dawb ionic nrog cov mis NaOH. Nws yog lub hauv paus corrosive heev thiab alkali uas decomposes lipids thiab proteins ntawm qhov kub thiab txias thiab tej zaum yuav ua rau mob hnyav heev. Nws yog heev soluble nyob rau hauv dej, thiab yooj yim absorbs noo noo thiab carbon dioxide los ntawm huab cua. Nws muaj ntau yam kev siv, xws li ua iav, detergents, thiab xab npum, softening dej thiab tshem tawm impurities, ua raws li ib tug sib piv tus neeg sawv cev nyob rau hauv kev kho mob imaging, thiab muab ib co minerals rau lub cev thiab cov av. thiab tsim cov tshuaj alkaline heev. Qhov kev daws teeb meem no yog corrosive rau cov khoom siv organic thiab tuaj yeem ua rau kub hnyiab heev thaum sib cuag nrog daim tawv nqaij lossis qhov muag. Caustic soda pearls yog cov hauv paus muaj zog thiab ua haujlwm zoo nrog cov kua qaub los tsim cov ntsev thiab dej. Lawv kuj koom nrog ntau yam tshuaj tiv thaiv, xws li saponification, neutralization, thiab hydrolysis. Tsis tas li ntawd, lawv tuaj yeem decompose cov organic tebchaw los ntawm kev hloov pauv nucleophilic.

Daim ntawv thov:
1. Siv nyob rau hauv kev tsim cov ntawv thiab cellulose pulp. Nws yog siv nyob rau hauv cov txheej txheem pulping los rhuav tshem lignin thiab cais cellulose fibers, thaum kawg pab rau zus tau tej cov ntaub ntawv zoo.
2. Hauv kev tsim cov xab npum thiab cov khoom siv hluavtaws, sodium hydroxide yog siv los ua cov khoom tseem ceeb. Nws ua hauj lwm raws li lub hauv paus muaj zog nyob rau hauv saponification cov tshuaj tiv thaiv, qhov twg nws reacts nrog fatty acids los tsim xab npum molecules.
3.Nyob rau hauv kev lag luam textile, sodium hydroxide pom kev siv hluav taws xob ua tus neeg saib xyuas daim ntaub, tus neeg saib xyuas scouring, thiab tus neeg saib xyuas txhob lo lo ntxhuav. Raws li tus neeg sawv cev desizing, nws pab tshem tawm cov neeg sawv cev ntawm cov ntaub, tso cai rau cov xim zoo dua nkag mus thiab ua tiav.
