Cov tshuaj calcium hydroxide ntshiab yog cov tshuaj lom neeg zoo thiab muaj ntau yam kev siv. Cov ntawv thov zoo kawg nkaus ntawm calcium hydroxide ntshiab, cia peb mus saib.
Cov txiaj ntsig thiab kev siv ntawm Top Choosing Chemical CaOH2:
Calcium hydroxide ntshiab yog hmoov dawb, sib tov ntawm calcium oxide thiab dej tau los ntawm kev sib tov calcium hydroxide nrog ob npaug ntawm cov dej theoretical. Nws yog lub hauv paus thiab nws rov pib dua cov kua qaub yog li nws yog cov khoom xyaw zoo meej rau ib yam dab tsi zoo li antacids. Nws kuj tseem siv rau hauv kev ua liaj ua teb kom txhim kho cov av zoo thiab hauv kev kho dej khib nyiab. Yog tias koj tau txhuam koj cov hniav nrog cov tshuaj txhuam hniav (lossis yaug koj lub qhov ncauj nrog cov tshuaj ntxuav qhov ncauj) uas tshaj tawm cov khoom xyaw ntxiv ntawm calcium, ces koj muaj cov tshuaj no hauv nws daim ntawv yooj yim los ua tsaug rau kev pab kom tawv thiab tiv thaiv koj cov hniav tiv thaiv cov kab noj hniav. Nrog rau tag nrho cov kev siv thiab plusses no, nws tsis yog qhov xav tsis thoob tias calcium hydroxide ntshiab yog ib qho ntawm cov kev xaiv nrov tshaj plaws rau txhua yam.
Calcium hydroxide ntshiab yog hmoov dawb nrog qhov ceev ntawm 2.24 g / cm3. Hauv kev tsim kho nws yog siv los ua plaster thiab mortar. Hauv kev lag luam zaub mov nws yog siv rau hauv kev tsim cov pickles thiab khaws cia txiv hmab txiv ntoo. Hauv kev kho hniav, ua cov calcium hydroxide kuj tseem siv ua cov khoom siv rau kev npog cov plaub hau, ntxiv rau kev pab ua ib daim ntawv ntawm cov cement ib ntus, hu ua significant, thiab yog cov khoom xyaw tseem ceeb hauv kev tsim cov tshuaj rau kev txhaws cov hauv paus hniav. Cov tshuaj lom neeg no kuj tseem tuaj yeem pom hauv cov khoom siv plaub hau ua tus kho pH thiab ib daim ntawm kev tsim cov plaub hau noj qab haus huv. Calcium hydroxide ntshiab yeej yog cov khoom xyaw nthuav, nrog ntau yam kev siv thiab kev siv.
Calcium hydroxide, tsis muaj npe, yog ib qho oxide ntawm calcium uas tsim cov hauv paus ntawm cov txiv qaub slaked. Top Choosing Chemical's pure calcium hydroxide yog ib qho hmoov dawb nrog qhov ceev ntawm 2.24 g / cm3. Cov tshuaj thaum ntxiv rau hauv dej, hydrates thiab hloov pauv sai sai mus rau hauv txiv qaub thaum hloov pauv cua sov thiab tsim cov kua txiv qaub slaked. Ib qho kev siv rau cov tshuaj no yog xws li hauv kev kho av acid lossis hauv kev ntxuav dej. Tsis tas li ntawd, calcium hydroxide nws tus kheej yog sparingly soluble hauv dej, thiab yog li tuaj yeem khaws cia rau lub sijhawm ntev yam tsis muaj kev puas tsuaj. Kev paub txog kev tshawb fawb ntawm calcium hydroxide ntshiab yog li cas peb xam tawm cov txiaj ntsig thiab kev siv ntawm cov khoom xyaw zoo kawg no los ntawm ntau lub lag luam.
Cov calcium hydroxide ntshiab ntawm Top Choosing Chemical yog cov khoom xyaw niaj hnub. Cov kua qaub no muaj nyob rau hauv kev lag luam khoom noj thiab tshuaj kom khaws cov zaub thiab txiv hmab txiv ntoo hauv cov kaus poom. Hauv kev tsim kho vaj tse, nws tau muab tso rau hauv cov cement kom khov. Cov calcium hydroxide ntshiab yog siv los ua cov khoom siv los lo rau ntoo kub hnyiab, ua cov dej mos hauv cov khoom siv depilatory, thiab hauv whitewash ua cov tshuaj tiv thaiv. Ntshiab lossis calcium hydroxide ntuj kuj tseem siv tau los txhim kho tus nqi thiab cov yam ntxwv muaj txiaj ntsig ntawm cov khoom sib xyaw no.
Siv rau txhua yam lag luam. Hauv kev ua liaj ua teb nws siv rau cov av acidic kom nce pH ntawm cov av rau kev tsim cov qoob loo avcultpH / cov uas rhiab rau cov av acidic. Nws kuj siv rau hauv kev lag luam ntawv, textile thiab yas. Ntshiab calcium hydroxide ntxiv yog ib yam khoom uas ua rau cov hniav sib zog, osmotic: cov hauv paus hniav, tiv thaiv, tiv thaiv kev hnav, thiab ntawm chav kawm yog ib yam khoom uas ua rau cov hniav sib zog. Kev siv calcium hydroxide ntshiab yuav siv tau; thiab yog li ntawd, nws tuaj yeem hais tias nws yog ib qho tseem ceeb hauv peb lub neej txhua hnub thiab tuaj yeem pom tias yog cov khoom xyaw tseem ceeb hauv ntau yam khoom uas peb siv.
