Ib txheej txheem rau kev npaj sodium hypophosphite, suav nrog kho cov dej sib xyaw ntawm calcium hydroxide thiab sodium carbonate nrog dawb phosphorus, cov tshuaj tiv thaiv sib xyaw ua kom sov ntawm qhov kub ntawm li 70 txog 100 C. rau ntau teev los tsim ib qho kev daws teeb meem ntawm sodium hypophosphite.
Sodium hypophosphite ua li cas?
Sodium hypophosphite (NaH2PO2) yog cov tshuaj txo qis tau los ntawm cov tshuaj tiv thaiv ntawm phosphorous nrog caustic soda thiab txiv qaub. Nws yog tsuas yog siv nyob rau hauv electrochemical nickel plating daim ntaub ntawv, whitening agent thiab raws li catalysts nyob rau hauv fiber-iav kev lag luam.
YKoj ua li cas calcium Hypophosphite?
Calcium hypophosphite tuaj yeem npaj los ntawm cov txheej txheem nruab nrab lossis cov txheej txheem hluavtaws ntawm txiv qaub thiab daj phosphorus [1]. Neutralization txheej txheem txhais tau hais tias neutralization ntawm hypophosphite thiab slaked txiv qaub tau txais calcium hypophosphite.
Puas yog sodium hypophosphite lom?
Tsis yog yam khoom txaus ntshai raws li GHS. Inhalation Tej zaum yuav muaj teeb meem yog tias nqus tau. Tej zaum yuav ua rau mob ua pa ua pa.
Sodium hypophosphite siv rau dab tsi?
Sodium hypophosphite yog siv los ua tus neeg sawv cev txo tus neeg sawv cev, catalyst & stabilizer, thiab tshuaj lom neeg nruab nrab. Sodium hypophosphite ua raws li kev txo tus neeg sawv cev rau electroless npib tsib xee plating daim ntawv thov, uas pom nws siv nyob rau hauv electronics thiab automotive kev lag luam.
