Khoom:
Sodium hydroxide muaj zog alkalinity thiab muaj zog corrosiveness.Nws tuaj yeem siv los ua cov kua qaub nruab nrab, sib piv cov npog ntsej muag, cov dej nag, nag lossis daus npog tus neeg saib xyuas, tus neeg tsim xim, tus neeg sawv cev saponification, tev tus neeg saib xyuas, tshuaj ntxuav tes, thiab lwm yam.
Sodium hydroxide muaj zog alkalinity thiab muaj zog hygroscopicity.Nws yog ib qho yooj yim rau dissolve nyob rau hauv dej thiab muab tawm tshav kub thaum dissolving.Cov tshuaj aqueous yog alkaline thiab greasy.Nws yog corrosive heev thiab corrosive rau fibers, tawv nqaij, iav thiab ceramics.Nws reacts nrog txhuas thiab zinc, non-metallic boron thiab silicon muab tawm hydrogen, disproportionation nrog halogen xws li chlorine, bromine thiab iodine, neutralizing nrog acids los tsim ntsev thiab dej.
Daim ntawv thov
Sodium hydroxide tsuas yog siv hauv papermaking, cellulose pulp ntau lawm, xab npum, hluavtaws detergent, hluavtaws fatty acid ntau lawm thiab tsiaj thiab zaub roj refining.Nws yog siv los ua tus neeg sawv cev desizing, tus neeg sawv cev scouring thiab mercerizing tus neeg sawv cev hauv textile printing thiab dyeing kev lag luam.Kev lag luam tshuaj yog siv los tsim borax, sodium cyanide, formic acid, oxalic acid, phenol, thiab lwm yam. Petroleum kev lag luam yog siv rau refining roj av cov khoom thiab drilling av nkos nyob rau hauv cov roj teb.Nws kuj yog siv rau hauv kev kho deg ntawm alumina, zinc thiab tooj liab, iav, enamel, tawv, tshuaj, xim thiab tshuaj tua kab.Khoom noj khoom haus qib yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li acid neutralizer, tev tus neeg sawv cev rau txiv kab ntxwv thiab txiv duaj, tshuaj ntxuav tes rau lub raj mis thiab cov kaus poom, decolorizer thiab deodorizer.
