Cov Ntawv Thov
Sodium carbonate, feem ntau yog hu ua Siaj Tshauv, yog ib qho kev sib xyaw ua ke nrog cov ntawv thov dav hauv kev lag luam, tsev neeg, thiab kuaj kab. Hauv kev lag luam, nws yog siv rau hauv iav tsim khoom, dej ua si, tshuaj ntxuav, thiab cov ntawv ntau lawm. Nws ua hauj lwm rau lub xov tooj ntawm cov pH, thiab cov tshuaj tiv thaiv ua tshuaj sodium, suav nrog kev tsim cov sodium bicarbonate, silicates, thiab carbonates. Hauv chaw soj ntsuam, sodium carbonate yog ua haujlwm raws li tus txheej txheem reagent, buffering tus neeg sawv cev, thiab cov txheej txheem kom qhuav thiab khoom siv hluavtaws. Nws tseem siv nyob rau hauv kev ua zaub mov ua raws li cov kev tswj hwm acidality thiab keeb kwm sawv cev.
Cov txiaj ntsig
Cov txiaj ntsig ntawm sodium carbonate suav nrog nws muaj zog alkalinate suav nrog nws muaj zog alkalinate, siab solubility, thiab tus nqi {- ua hauj lwm ua tau zoo. Nws ua tau zoo nyob rau cov acids, cov dej muag muag, thiab txhim kho kev tu cov xab npum. Nws cov kev ruaj khov thiab tsawg toxicity ua nws kev nyab xeeb rau siv hauv zaub mov, kev lag luam, thiab kev kuaj thiab kuaj cov ntawv thov. Sodium carbonate cov tshuaj tiv thaiv kev ua haujlwm tseem ceeb, muab cov txheej txheem zoo cim hluav taws xob, thiab txhawb nqa cov txheej txheem ib puag ncig zoo vim nws tsis- kev phom sij. Nws cov khoom muaj ntau yam ua rau nws tsis tseem ceeb nyob thoob plaws ntau txoj haujlwm.
