Raws li, cov khoom xyaw hauv tshuaj dawb yog dab tsi?
Muaj ntau ntau hom tshuaj dawb:
- Cov tshuaj dawb feem ntau muaj sodium hypochlorite.
- Cov pa tshuaj dawb muaj hydrogen peroxide lossis cov tshuaj tso tawm peroxide xws li sodium perborate lossis sodium percarbonate.
- Cov tshuaj dawb yog calcium hypochlorite.
Tsis tas li, puas yog tshuaj dawb los yog ntuj tsim? Hom tshuaj dawb tshaj plaws nyob rau niaj hnub no yog tshuaj tshuaj dawb, sodium hypochlorite lossis lwm yam ntsev ntawm hypochlorous acid.

Txawm li cas los xij, nws hloov tawm tias qee yam muaj sia, suav nrog tib neeg cov qe ntshav dawb, ua rau nws me me.
Ib yam li ib tus tuaj yeem nug, cov khoom xyaw ntawm cov tshuaj dawb tuaj qhov twg?
Cov tshuaj chlorine tseem nyob hauv kev daws teeb meem, xws li sodium chloride (ntsev ntsev), lossis calcium chloride. Cov tshuaj dawb no yog ua los ntawm cov pa tshuaj chlorine ua los ntawm cov tshuaj sodium hydroxide (lye) lossis calcium hydroxide (nrawm). Cov tshuaj chlorine tuaj yeem tso tawm yog tias cov tshuaj dawb yog tov nrog cov kua qaub.
Tshuaj dawb ua tshuaj li cas?
Cov ntaub ntawv raw siv rau ua tshuaj dawb yog cov tshuaj chlorine, dej qab ntsev, thiab dej. Tshuaj chlorine thiab dej qab ntsev yog tsim los ntawm kev tso hluav taws xob los ntawm cov tshuaj sodium chloride ntsev tov. Cov txheej txheem no hu ua electrolysis. Sodium chloride, feem ntau paub tias yog ntsev ntsev, los ntawm ob qho me me lossis cov qhov dej hauv av.
