Calcium nitrate, tseem paub los ntawm cov npe tshuaj "calcium nitrate", "txiv qaub los yog calcium nitrate", yog cov ntsev tsis muaj zog ntawm nitric acid, uas yog cov tsis muaj xim cubic crystals. Lub compound muaj ib tug high degree ntawm hygroscopicity. Qhov ceev ntawm cov compound yog 2.36 g / cm³, nws melting point yog 561 ° C, nws boiling point yog 151 ° C. Nyob rau hauv ib txwm cia tej yam kev mob, nws yog tsis-flammable thiab tawg-pov thawj. Nyob rau hauv qhov kub ntawm -60 ° C - +155 ° C, stability yog manifested, uas distinguishes calcium nitrate. Cov mis ntawm cov tshuaj yog Ca(NO3)2.
Calcium nitrate yog tau los ntawm kev nqus nitrogen oxides nrog mis nyuj ntawm txiv qaub los yog los ntawm kev nthuav tawm limestone rau HNO3. Granular calcium nitrate yog tau los ntawm qhov kub thiab txias neutralization ntawm HNO3 nrog ntuj limestone.
Calcium nitrate yog universal physiological alkaline chiv haum rau cov av uas muaj calcium tsawg. Calcium nitrate yog haum rau tag nrho cov av. Nws siv tshwj xeeb tshaj yog tsim nyog rau acidified, xuab zeb,alkaline av. Calcium yog qhov tsim nyog rau kev noj qab haus huv thiab tsim nyog ntawm cov ntaub so ntswg, ua kom lub zog ntawm lawv cov phab ntsa ntawm tes, thiab txhim kho cov txiv hmab txiv ntoo zoo. Calcium nitrate txhim kho kev nthuav qhia ntawm cov khoom, prolongs lawv lub neej txee. Nws kuj yog siv los tiv thaiv cov kab mob provoked los ntawm qhov tsis muaj calcium (core lossis sab saum toj rot, marginal nplooj hlawv thiab lwm yam). Cov chiv yog siv rau hauv daim ntawv ua kua. Rau cov tshuab hydroponic, calcium nitrate yog tib txoj hauv kev kom tau dej-soluble calcium.
Tau txais cov khoom sib txuas hauv daim ntawv ntawm granules thiab crystals tau nthuav dav dav ntawm nws daim ntawv thov. Granular calcium nitrate yog non-caking, non-hygroscopic, yooj yim siv.
Crystalline calcium nitrate yog siv dav hauv kev tsim kho thiab kev lag luam. Nws yog ib tug complex additive nkag mus rau hauv lub pob zeb thiab lub tsev mortars nyob rau hauv thiaj li yuav txhim kho lawv cov khoom thaum lub sij hawm tsim kho ntawm monolithic reinforced pob zeb thiab pob zeb vaj tse. Cov tebchaw no yog siv los ua cov pob zeb tawv tawv accelerators. Lawv ua kom cov dej tsis kam ntawm cov pob zeb, ua kom nws lub sijhawm teeb tsa yam tsis hloov pauv qhov dej (rheology) los ntawm kev siv cov yas yas. Calcium nitrate yog siv los ua kom Frost tsis kam, tawg lub zog ntawm cov pob zeb, txo cov pob zeb shrinkage thiab tawg tsim, qeeb cov txheej txheem corrosion ntawm cov hlau reinforcing siv hauv pob zeb, tshwm sim los ntawm cov ntsiab lus ntawm chlorides.
Nws kujsiv nyob rau hauv kev npaj cov roj zoo cements, uas yog npaj rau cementing roj qhov dej, nyob rau hauv kev npaj cov kev daws teeb meem siv nyob rau hauv kev kho cov roj qhov dej, nrog rau cov drilling kua.
Calcium nitrate yog siv hauv pyrotechnics, vim nws yog ib qho ntawm cov khoom siv ntawm cov khoom tawg. Muaj tseeb, nws siv qee qhov txwv vim nws muaj zog hygroscopicity.
Calcium nitrate kuj tau siv dav hauv kev tsim cov tshuaj, tshuaj khib nyiab, fiberglass thiab cov khoom siv hauv tsev.
