Calcium nitrate. Properties na Ngwa

calcium nitrate, a makwaara dị ka omenala aha "calcium nitrate" "wayo ma ọ bụ calcium nitrate" bụ inorganic nnu nke nitric acid bụ a colorless cubic kristal. The compound bụ ukwuu hygroscopic. compound njupụta - 2,36 g / cm³, a agbaze okpomọkụ - 561 ° C, esi ebe - 151 Celsius C. N'okpuru nkịtị ọnọdụ nke nchekwa bụ ndị na-abụghị flammable na-abụghị na-agbawa agbawa ihe onwunwe. Na okpomọkụ nso -60 ° C - +155 ° C egosiwokwa kwụsie ike nke gosiri ọdịiche calcium nitrate. Formula chemical compound - Ca (NO3) 2.

Calcium nitrate na-akwadebe site absorption nke nitrogen oxides na mmiri ara ehi nke wayo ma ọ bụ HNO3 mmetụta na nkume nzu. The granulated calcium nitrate na-akwadebe site na usoro nke ala-okpomọkụ neutralization HNO3 eke nkume nzu.

calcium nitrate - a eluigwe na ala n'ahụ alkaline fatịlaịza, adabara Ona na ala calcium ọdịnaya. Calcium nitrate bụ adabara niile Ona. Karịsịa ihe kwesịrị ekwesị maka ya ngwa acidified, ájá, alkali Ona. Calcium dị oké mkpa maka ahụ ike na ihe kwesịrị ekwesị mmepe nke osisi anụ ahụ, na-amụba n'ike nke ha cell mgbidi, rụọ àgwà nke mkpụrụ. Calcium nitrate mma na marketability nke ngwaahịa, gbatịrị adị ndụ. Ọ na-eji na-egbochi ọrịa iwe na calcium erughi (isi ma ọ bụ na apical ire ere, akwukwo ihu apa ọkụ na ndị ọzọ). The fatịlaịza na-etinyere na mmiri mmiri n'ụdị. N'ihi hydroponic systems calcium nitrate - nanị ụzọ nweta a mmiri-soluble calcium.

Nkwadebe nke ogige n'ụdị nsogbu dị iche iche na kristal budata mụtakwuo akporo nke ya ngwa. Granulated calcium nitrate adịghị achicha, bụghị hygroscopic, mfe iji.

Crystalline calcium nitrate na ọtụtụ-eji ụlọ na ụlọ ọrụ. Ọ bụ a mgbagwoju mmako ẹkenam n'ime ihe na ogbunigwe iji mma ha Njirimara na-ewu monolithic ihe na mesikwuru ihe owuwu. A ogige na-eji dị ka accelerators nke ekwesi ihe. Ha dịkwuo mmiri na-eguzogide nke ihe na klas, gbatịrị ọdịda ya enweghị agbanwe eruba (rheology) site n'iji plasticizers. Calcium nitrate na-eji dịkwuo ntu oyi na-eguzogide nke ihe na-agbasa ike, belata shrinkage na deformation nke ihe cracking, onye na-adịghị corrosion Filiks rebar ígwè eji ihe, n'ihi na elu chloride ọdịnaya.

Ọ na-eji na njikere nke cements, nke na-zubere maka simenti mmanụ olulu mmiri, na nkwadebe na nkà na ụzụ ngwọta na-eji na idozi gas olulu mmiri, tinyere egwu oke mmiri.

Calcium nitrate na-eji na pyrotechnics, dị ka bụ otu n'ime constituent ọcha nke na-agbawa agbawa. Otú ọ dị, ya ngwa n'ihi na nke siri ike hygroscopic dịtụ mmachi.

calcium nitrate Ọ na-n'ọtụtụ ebe na na mmepụta nke na, akọrọ ụlọ mixes, iko-mesikwuru plastik na ụlọ ihe.
