Yellow flakes Thiab Liab flakes Industrial Sodium Sulfide
Siv los ua tus neeg sawv cev los yog tus neeg sawv cev mordant hauv kev ua cov tshuaj zawv plaub hau, ua tus neeg sawv cev hauv kev lag luam uas tsis yog ferrous metallurgical, ua mordant tus neeg sawv cev rau paj rwb tuag, siv hauv kev lag luam tanner, hauv khw muag tshuaj kev lag luam ua qee yam phenacetin, hauv kev lag luam electroplate, rau hydriding galvanize. Cov tshuaj anhydrous yog cov dawb crystal, yooj yim deliquescent, thiab muaj solubility hauv dej (15.4G / lOOmLwater ntawm 10 ° C.Thiab 57.2G / OOmLwater ntawm 90 ° C.).Thaum nws reacts nrog acid, hydrogen sulfide yog generated.Nyob soluble nyob rau hauv cawv, insoluble nyob rau hauv ether.Cov tshuaj aqueous yog alkaline, yog li nws tseem hu ua sulfide alkali.Dissolved nyob rau hauv sulfurgenerated sodium polysulfide.Industrial khoom feem ntau muaj impurities rau liab, xim av liab, daj block.Corrosive, toxic.In the airoxidation of sodium thiosulfate.
