Caustic dej qab zib kuj tseem hu ua caustic dej qab zib thiab caustic dej qab zib. Nws cov tshuaj lom neeg lub npe yog sodium hydroxide thiab nws cov mis nyuj yog naoh. Nws yog ib qho ntawm peb lub acids thiab ob lub hauv paus hauv kev lag luam tshuaj lom neeg thiab yog ib qho tseem ceeb heev cov khoom siv raw. Heev corrosive muaj zog alkali, feem ntau yog nyob rau hauv daim ntawv ntawm Flakes dawb lossis hais tawm, tuaj yeem ua kom yaj nyob rau hauv Methanol thiab ethanol. Cov tshuaj alkaline no yog Deliquescent thiab yuav nqus dej vapor hauv cov pa nrog rau acidic roj xws li carbon dioxide.
Caustic Soda tau ntev tau hu ua ib qho khoom lag luam alkaline. Xyoo 1787, Kws Kho Mob Nicolas Lelanc (1762-1806) tsim cov txheej txheem tsim nyog rau kev tsim cov sodium hydroxide los ntawm cov lus ntsev thiab nqa tawm cov khoom loj loj. Xyoo 1887, Swedei Chemist Arrhenius nrhiav tau cov kua qaub-paus ionization ionization lub tswv yim (piv txwv li, cov kua qaub-paus ntawm aqueous daws). Nws tau npaj siab tias cov kua qaub nyob rau hauv uas txhua txoj kev tsim tawm los ntawm ionizes yog cov kev daws teeb meem, thiab cov hauv paus yog cov tshuaj hauv cov kev daws teeb meem aqueous. Tag nrho cov act tsim los ntawm ionization yog hydroxide ions. Txij thaum ntawd los, lub alkalinity ntawm sodium hydroxide tau hais meej meej. Caustic Soda tuaj yeem siv los ua cov dej phwj tuaj qaug zog kom tshem tawm cov blockes hauv cov kav dej lim dej, ntau ntau cov roj, cov plaub hau pov tseg. Caustic sis cov dej qab zib muaj cov txiaj ntsig zoo ua rau cov khoom siv no. Thaum caustic dej qab zib yog yaj hauv dej, nws generates tshav kub, uas tuaj yeem ua kom nrawm nrawm thiab txhawb cov nyhuv ntxuav. Yog li yuav ua li cas thiaj siv caustic dej qab zib rau kev kho kom tsis taus thiab kom tsis muaj menyuam?
Nyob rau hauv ib txwm muaj xwm txheej, 2% -4% caustic sod kev daws yuav pab tau cov kab mob feem ntau. Ntxiv 2-4 phaus ntawm caustic dej qab zib rau 100 phaus dej. PHEM LUB NPE Cov kev npaj tau nyob nruab nrab ntawm 10 thiab 14, thiab Ph ntawm caustic sophfection thiab kom tsis muaj menyuam yaus yuav tsum tau ua kom muaj zog ntawm txoj kev lossis cov kev taug kev taug kev, lossis Nws yooj yim dua rau kev siv rab phom txau. Txawm li cas los xij, cov phom dej muaj kev kub ntxhov siab tsis tuaj yeem siv los tshuaj tsuag, yog txawm tias ib qho kev siv nkaus xwb yuav ua rau cov tshuab hloov thiab khoom siv.
Caustic dej qab zib dej tsis tuaj yeem tiv toj ncaj qha. Caustic Soda Dej yog cov corrosive thiab khaus thiab tuaj yeem ua rau muaj kev kub ntxhov rau ntawm daim tawv nqaij thiab cov ntaub nyias nyias nyias. Yog li ntawd, Causic Soda dej tsis tuaj yeem raug sprinkled rau tib neeg lossis lwm yam tsiaj muaj sia. Feem ntau tib neeg siv caustic dej qab zib dej rau tshuaj tua kab mob. Tshuaj tua kab mob thiab tshuaj ntxuav tawm hauv qhov chaw pub dawb. Qhov feem ntau siv thaj chaw yog cov neeg ua haujlwm aisle. Hauv kev pom ntawm cov kab mob loj corrition loj, nyob qhov twg Caustic Soda dej nyob, muaj feem ntau paj uas tsis tuaj yeem tawg thiab nyom uas tsis tuaj yeem loj hlob. Cov chaw tshuaj tua kab mob nrog cov dej qab zib caustic yuav tsum tau ntxuav ua ntej ua ntej siv. Feem ntau cov neeg tshuaj tua kab nrog caustic dej qab zib dej thiab tom qab ntawd ntxuav nws nrog cov kais dej ntau dua kaum teev. Yog tias nws tsis tau huv si, yuav muaj cov khoom qab zib ntawm txoj kev sab nraud, uas tuaj yeem ua rau tib neeg lossis muaj kev sib chwv. Caustic Soda tuaj yeem siv los ua cov tshuaj tua lawv tus kheej sai. 5 ~ 10% CNIVIC SODA dej yog qhov ua tau zoo hauv kev tshem cov nroj. Cov nyhuv muaj peev xwm pom tau li ntawm 20 feeb, thiab cov nroj yuav qhuav ua ke ib nrab ib hnub. Nws ua sai dua li paquat tshuaj tua kab. Qhov tsis zoo yog tias nws loj hlob rov qab sai. Caustic dej qab zib yog cov xeb zoo thiab ua rau cov khoom siv. Yog tias cov khoom siv tsis yog galvanized kav, peb yuav tsum ntxuav lawv sai li sai tau tom qab siv caustic dej qab zib. Ib qho ntxiv, thaum peb siv cov dej qab zib caustic, peb yuav tsum tau them nyiaj tshwj xeeb rau kev tiv thaiv kev nyab xeeb, tsom iav, thiab hnav lub tsho ntev thiab hnav ris tsho ntev thiab hnav ris tsho ntev. Nws yog ib qho tseem ceeb kom tiv thaiv cov dej caustic los ntawm kev hlawv cov tawv nqaij thiab cov tawv nqaij qog. Yuav luag txhua tus neeg uas tuaj ntsib CAustic dej qab zib ntawm kev ua haujlwm tau paub qhov muag hluav taws kub thiab kev mob ntawm kev siv cov khoom noj caustic. Qee tus neeg tau lub qhov ntswg thaum lawv hnov ntxhiab tsw ntawm caustic dej qab zib. Qhov no txhais tau tias qhov tsis hnov tsw ntawm caustic soda hlawv mucosa vim yog kev tiv thaiv tsis raug. Caustic dej qab zib tsis tuaj yeem sib xyaw nrog cov hmoov hlau thiab hmoov txhuas. Tom qab caustic dej qab zib yog tov nrog cov hmoov hlau los yog hmoov txhuas, nws yuav ua nruj ua tsiv thaum raug cov dej npau npau, tsim kom muaj cua sov thiab tso dej kub thiab tso tawm hydrogen. Yav dhau los, muaj ntau yam zais pa me me hauv cov chaw nyob deb nroog uas siv cov hlau tso tsheb hlau luam ua kom hydrogen-inflated zais pa.
