Cov khoom thiab siv los ntawm dej qab zib tshauv thiab caustic dej qab zib

Alkali, kev paub txog kev paub zoo li sodium hydroxide (Naoh), feem ntau yog hu ua caustic dej qab zib thiab caustic dej qab zib, yog ib qho muaj zog alkali nrog kev txhim kho corrosiveness. Nws yog corrosive rau fibers, daim tawv nqaij, iav, ceramics, thiab lwm yam, thiab tso tawm thaum tshav kub kub thaum yaj. Caustic Soda tuaj yeem muab faib ua ob pawg: "Kua alkali" thiab "Khoom Plig Alkali". Khoom Plig Alkali yog cov khoom loj heev NOOH, thiab kua Alkali yog ib qho kev daws teeb meem uas muaj hnub nyoog nrog cov ntsiab lus tshwj xeeb ntawm 30%, 328%, 49%, thiab 50% siab. Hauv kev lag luam ntsuas kev lag luam, nws tuaj yeem siv ua cov kua qaub neutralizer, decolorizer, thiab deodorizer. Hauv kev lag luam nplaum, nws yog siv los ua cov hmoov txhuv nplej siab thiab nruab nrab.

Hauv lub xeev ruaj khov, caustic dej qab zib tuaj yeem muab faib ua nplaim hluavtho dej qab zib, khoom CeTustic dej qab zib thiab granular caustic dej qab zib. Fleustic dej qab zib yog dav siv nyob rau hauv kev lag luam thiab kev ua liaj ua teb, tshuaj tua kab, xab npum, thiab lwm yam Rau cov neeg siv nrog cov kev xav tau siab alkalinity yuav tsum muaj, caustic dej qab zib yog qhov zoo dua li flake caustic dej qab zib. Flake Caus Soda tuaj yeem siv los ua tus desiccant thiab muaj lub zog muaj peev xwm nqus dej molecules nyob saum huab cua. Tus nqi ntawm Caustic Soda yog feem ntau kim dua li flake caustic dej qab zib.

Lwm lub hauv paus hauv "peb cov kua qaub thiab ob lub hauv paus" yog "soda tshauv"
Dej qab zib tshauv yog na2co3, thiab kev corrosiveness ntawm dej qab zib tshauv tsis yog muaj zog li ntawm caustic dej qab zib. Caustic dej qab zib belongs rau "alkali", thaum dej qab zib tshauv belongs rau "ntsev". Lub ntsiab tivthaiv yog sodium carbonate, uas yog alkaline thaum yaj hauv dej. Sodium carbonate uas muaj kaum lub crystal dej yog tsis muaj xim siv lead ua. Nws cov muaju yog tsis ruaj khov thiab yooj yim huab cua hauv huab cua los ua cov hmoov dawb dawb. Cov ntaub ntawv raw ntawm caustic dej qab zib thiab dej qab zib tshauv yog ob qho tib si "ntsev", thiab ob qho tib si yog kev lag luam ntsev. Ntau tshaj li 90% ntawm kuv lub teb chaws cov ntsev nyoos yog siv rau dej qab zib tshauv thiab caustic sodias, ntawm uas caustic tshauv suav rau txog 38.2%. Cov dej hauv qab ntawm Caustic dej qab zib thiab dej qab zib tshauv Txij li ob qho muaj tib lub hauv paus, lawv cov dej ntws los kuj muaj qee qhov kev sib tshooj sib tshooj. Tus nqi sib txheeb ntawm caustic dej qab zib thiab dej qab zib tshauv yog qhov tseem ceeb, nrog txoj kev sib txheeb ntawm coefficient ntawm 0.7, thiab cov ncauj lus zoo ib yam nkaus.

Cov kev sib raug zoo ntawm caustic dej qab zib thiab dej qab zib tshauv yog tias dej qab zib tuaj yeem tau txais los ntawm cov cua sov caustic dej qab zib. Thaum caustic dej qab zib yog rhuab rau qhov kub thiab txias, thiab sodium carbonate, thiab sodium carbonate yog soda tshauv. Yog li ntawd, caustic dej qab zib yog ib qho ntawm cov ua ntej ntawm dej qab zib tshauv.
