Calciumhydroxide CAS: 1305-62-0

Calcium hydroxide pom ntau yam kev siv thoob plaws ntau yam lag luam thiab cov sectors. Hauv kev tsim kho thiab kev tsim kho vaj tse, nws yog siv rau hauv kev npaj cov mortar thiab concrete, qhov twg nws ua haujlwm ua tus neeg sawv cev tseem ceeb, pab txhawb rau lub zog thiab kev ruaj khov ntawm cov khoom siv hauv tsev no. Nws siv rau hauv kev ruaj khov av pab txhim kho lub peev xwm thauj khoom thiab kev ua tau zoo ntawm cov av hauv kev tsim kho txoj kev thiab cov haujlwm tsim kho vaj tse. Hauv kev lag luam ib puag ncig, calcium hydroxide ua lub luag haujlwm tseem ceeb hauv cov txheej txheem kho dej khib nyiab. Nws yog siv ua tus neeg tswj flocculant thiab pH rau neutralizing acidic effluents, precipitating impurities, thiab tshem tawm cov hlau hnyav ntawm cov dej khib nyiab kev lag luam, yog li txhawb nqa kev ua raws li ib puag ncig thiab kev tswj hwm kev ua qias tuaj. Ntxiv mus, calcium hydroxide yog siv dav hauv kev ua liaj ua teb ua ib feem ntawm cov chiv raws li txiv qaub thiab kev hloov kho av. Nws qhov xwm txheej alkaline pab kom sib npaug av pH, txo acidity, thiab txhim kho kev muaj cov as-ham, txhawb nqa cov xwm txheej zoo tshaj plaws rau kev loj hlob ntawm cov nroj tsuag thiab kev cog qoob loo. Hauv kev lag luam zaub mov, calcium hydroxide yog siv rau hauv kev ua zaub mov, tshwj xeeb tshaj yog hauv kev tsim cov pob kws tortillas qhov twg nws yog siv rau nixtamalization, cov txheej txheem ntawm kev kho pob kws nrog cov kua alkaline. Txoj kev kho mob no ua rau cov noob mos mos, txhim kho cov khoom noj khoom haus zoo, thiab txhim kho cov saj, cov qauv, thiab cov ntxhiab tsw hauv cov khoom tsim tawm. Ntxiv mus, calcium hydroxide ua haujlwm ua cov khoom xyaw tseem ceeb hauv cov ntaub ntawv kho hniav, tshwj xeeb tshaj yog hauv kev tsim cov cements kho hniav thiab cov hauv paus hniav sealers. Nws cov khoom antimicrobial thiab biocompatibility ua rau nws muaj txiaj ntsig zoo hauv kev kho thiab endodontic cov txheej txheem, pab txhawb rau lub neej ntev thiab kev vam meej ntawm kev kho hniav. Ntxiv mus, calcium hydroxide yog siv rau hauv kev tsim cov tshuaj, suav nrog calcium stearate, uas yog siv ua cov roj nplua nyeem thiab tso tawm tus neeg sawv cev hauv ntau yam lag luam xws li plastics, roj hmab, thiab tshuaj. Nws cov ntawv thov hauv cov sectors no qhia txog nws qhov tseem ceeb ua ib qho sib xyaw ua ke nrog ntau yam kev koom tes rau ntau yam lag luam thiab daim ntawv thov.
