Calcium nitrate. Malo ndi mapulogalamu

Calcium nitrate, yomwe imadziwikanso ndi mayina a chikhalidwe monga "calcium nitrate", "calcareous or calcium nitrate", ndi mchere wamchere wa nitric, womwe ulibe makina osakanikirana. Pakompyuta ali ndi digirii yochuluka kwambiri. Kuchuluka kwake kwa palimodzi ndi 2.36 g / cm³, malo ake osungunuka ndi 561 ° C, ndipo malo otentha ndi 151 ° C. Pansi pa malo osungirako zachilengedwe izi ndi chinthu chosapsa, chophulika. Mu kutentha kwa -60 ° C mpaka +155 ° C, kukhazikika kumawonetseredwa, komwe kumasiyanitsa calcium nitrate. Njira ya mankhwala ndi Ca (NO3) 2.

Calcium nitrate imapezeka poyesa nitrojeni oxides ndi mkaka wa laimu kapena poonetsa HNO3 kuchepetsa. Granular calcium nitrate imapangidwa ndi njira yochepa yopanda kutentha kwa HNO3 ndi chilengedwe chamatope.

Calcium nitrate ndi chilengedwe chonse zamchere feteleza choyenera mchenga ndi otsika kashiamu wokhutira. Calcium nitrate ndi yabwino kwa dothi lonse. Choyenera makamaka ntchito yake pa dothi la acidified, sandy, alkaline. Calcium ndi yofunikira kuti chitukuko chabwino ndi choyenera cha tizirombo timene timapanga, kuwonjezera mphamvu za makoma awo, ndikukweza ubwino wa chipatsocho. Calcium nitrate imapangitsa kuti mankhwalawa apitirire, kupititsa patsogolo mapulumulo. Amagwiritsidwanso ntchito popewera matenda osowa chifukwa cha kusowa kwa calcium (zovuta kapena vertex zowola, kutsogolo kwa masamba ndi ena). Feteleza imagwiritsidwa ntchito mwa madzi. Kwa ma hydroponic, calcium nitrate ndiyo njira yokhayo yotulutsa calcium yosungunuka madzi.

Kukonzekera kwa chigawochi mwa mawonekedwe a granules ndi makhiristo kunachulukitsa kuchuluka kwa ntchito yake. Granulated calcium nitrate sichimawongolera, osati chogwiritsidwa ntchito, choyenera kugwiritsa ntchito.

Crystalline calcium nitrate amagwiritsidwa ntchito kwambiri pomanga ndi malonda. Ndizowonjezera zovuta zowonjezeredwa mu konkire ndi matope kuti apititse patsogolo katundu wawo pomanga konkireti yokhala ndi monolithic komanso nyumba za konkire. Mafakitalewa amagwiritsidwa ntchito monga konkire yolimba ya accelerators. Amawonjezera kalasi ya konkire ya madzi, kuonjezera nthawi yomwe imakhala popanda kusinthasintha (rheology) chifukwa chogwiritsira ntchito mapulasitiki. Calcium nitrate amagwiritsidwa ntchito kuonjezera chisanu kukana, mphamvu ya konkire ya kuphulika, kuchepetsa kwa shrinkage kuwonongeka kwa konkire ndi kupasula, kutayika kwa kutukuka kwazitsulo pofuna kulimbikitsa zitsulo zomwe zimagwiritsidwa ntchito mu makina opangidwa ndi ma chloride.

Amagwiritsidwanso ntchito pokonzekera zipinda za mafuta, zomwe zimapangidwira kumanga zitsime za mafuta, pokonzekera njira zamakono zomwe zimagwiritsidwa ntchito pokonzanso zitsime zamadzi, kuphatikizapo kubowola madzi.

Calcium nitrate imagwiritsidwa ntchito mu pyrotechnics, chifukwa ndi imodzi mwa zinthu zomwe zimapangitsa kuti ziphuphu zisokonezeke. Zoona, kugwiritsa ntchito kwake chifukwa cha kuchuluka kwakukulu kwazomwe kuli kochepa.

Calcium nitrate Amagwiritsidwanso ntchito kwambiri pakupanga reagents, matope owuma, fiberglass ndi zipangizo.
