Dab tsi yog qhov sib txawv ntawm cov dej tshauv qab zib thiab caustic dej qab zib?

Dej qab zib tshauv thiab caustic dej qab zib yog ob qho tib si tsis tshua muaj tshuaj raw cov ntaub ntawv. Lawv yog ob qho tib si khib nyiab dawb thiab muaj cov npe zoo sib xws, uas tuaj yeem yooj yim tsis ntseeg neeg. Qhov tseeb, dej qab zib tshauv yog sodium carbonate (na ₂cox), thaum caustic dej qab zib yog sodium hydroxide (NAOH). Qhov ob yog tsis tib yam khoom ntawm txhua tus. Nws kuj tseem tuaj yeem pom los ntawm cov mis molecular uas sodium carbonate yog ib tug alkali, vim tias nws yog alkaline ua alkaline ua alkaline ua txiv ntoo, vim nws tseem hu ua Soda tshauv. Hauv qab no peb piav qhia txog qhov sib txawv ntawm ob qho kom meej los ntawm kev nthuav dav los ntawm ntau qhov.
Qhov sib txawv ntawm dej tshauv Caustic dej qab zib: Lub npe siv tshuaj lom yog sodium hydroxide, cov mis nyuj yog naoh.

2. Qhov sib txawv hauv lub cev thiab tshuaj cov khoom: soda tshauv yog ntsev. Sodium carbonate uas muaj kaum lub crystal cov dej yog qhov tsis muaj kob siv lead ua. Cov dej siv lead ua tsis ruaj khov thiab yooj yim huab cua, tig mus ua hmoov dawb na2co3. Nws yog cov electrolyte muaj zog thiab muaj cov khoom thiab cov hluav taws xob ruaj khov ntawm ntsev. , yooj yim soluble hauv dej, thiab nws cov kua aqueous yog alkaline. Caustic dej qab zib yog ib tug corrosive alkali, feem ntau nyob rau hauv daim ntawv ntawm flakes lossis granules. Nws yog yooj yim soluble hauv dej (nws tso tawm thaum tshav kub kub thaum yaj hauv dej) thiab tsim cov tshuaj alkaline. Nws tseem yog deliquescent thiab tuaj yeem yooj yim nqus dej los ntawm huab cua. Chav.

3. Qhov sib txawv hauv kev siv: dej qab zib tshauv yog ib qho ntawm cov khoom siv raw khoom tseem ceeb. Nws yog dav siv nyob rau hauv kev lag luam lub teeb, cov khoom siv txhua hnub, tsim kev lag luam, metallurgy, textum, tiv thaiv kev tiv thaiv hauv tebchaws, tshuaj thiab lwm thaj chaw. Nws yog siv los ua cov khoom siv raw rau tsim khoom lwm yam tshuaj lom neeg. Kev ntxuav tu, tshuaj ntxuav tshuaj, kuj siv hauv kev yees duab thiab tsom xam. Ua raws li los ntawm Metallurgy, Textiles, Roj av, Kws Muaj Txuj Ci Hauv Tebchaws, Tshuaj thiab lwm yam kev lag luam. Cov iav kev lag luam yog cov neeg siv khoom loj tshaj plaws ntawm cov tshauv Ntawm cov kev lag luam dej tshauv Caustic Soda tsuas yog siv hauv papermaking, cellulose pappaking, synthetic filty acids thiab kho cov tsiaj thiab zaub thiab cov rog. Nyob rau hauv textile luam ntawv thiab tawg ntawm kev lag luam dyim kev lag luam, nws tau siv ua cov neeg sawv cev rwb, cov neeg saib xyuas cov neeg sawv cev thiab muaj kev lom zem. Cov tshuaj lom neeg kev lag luam yog siv los tsim borax, sodium cyanide, formic acid, oxalic acid, oxalic acid, olroleum kev lag luam thiab hauv cov roj av drilling av nkos. Nws tseem siv nyob rau hauv kev kho cov npoo txhuas ntawm txhuas oxide, nws yog xim tooj liab zinc thiab zoo li hauv iav, txham, tshuaj, dyes thiab tshuaj tua kab. Cov khoom lag luam-cov khoom lag luam yog siv ua cov kua zaub Neutrus rau cov neeg ua zaub mov noj, raws li cov tshuaj ntxuav ua noj rau cov khoom noj uas khoob thiab cov kaus poom, nrog rau cov neeg sawv cev thiab tsis txaus ntseeg.
