Calcium nitrate. Izakhiwo kunye Izicelo

calcium nitrate, okwabizwa ngokuba amagama zemveli "calcium nitrate" "ngekalika okanye calcium nitrate" yi netyuwa ezingaphiliyo ye-nitric acid i ziikristale enemibala cubic. Le ephindeneyo hygroscopic kakhulu. compound Density - 2,36 g / cm³, lobushushu ukunyibilika a - 561 ° C, lokubila - 151 ° C. Phantsi kweemeko eziqhelekileyo ze USB non-olunokutsha izinto non-Uyadubula. In lobushushu uluhlu -60 ° C - +155 ° C uzinzo abonisa leyo umahluko calcium nitrate. Formula chemical compound - Ca (NO3) 2.

Calcium nitrate lalungiselela nokufunxwa kwenitrojeni kunye nobisi kwekalika okanye HNO3 wanefuthe lekalika. Le nitrate calcium granulated elungiswe indlela esezantsi-lobushushu neutralization HNO3 lekalika yendalo.

calcium nitrate - universal komzimba ialakalin isichumiso, ifanele Kwimihlaba isiqulatho calcium eliphantsi. Calcium nitrate ilungele ukuba yonke imihlaba. Ingakumbi kufanelekile ukuba isicelo yayo izimuncu, isanti, imihlaba kwealkali. Calcium kubalulekile kuphuhliso esempilweni nezifanelekileyo zomzimba zezityalo, ukwandisa amandla abo ezindongeni, ukuphucula umgangatho iziqhamo. Calcium nitrate kuphucula amathuba lweemveliso, usinika ithuba lokugcinwa. Iyasetyenziswa lokuthintela izifo nomsindo calcium ngxaki (core okanye ezibolileyo apical, igqabi edge itshileyo kunye nabanye). Le isichumiso ngendlela engamanzi. Kuba iinkqubo hydroponic calcium nitrate - ndlela kuphela ukufumana calcium amanzi ayaphela.

Ukulungiswa iikhompawundi ngohlobo granules kunye ziikristale banzi kakhulu imihlaba isicelo sayo. Granulated calcium nitrate ayinayo ikeyiki, hayi hygroscopic, kulula ukuyisebenzisa.

Crystalline calcium nitrate ngokubanzi asetyenziswe ekwakheni kunye noshishino. It is a additive entsonkothileyo kwangena eziphathekayo mortars ukwenzela ukuphucula iipropati zabo ekwakhiweni ngekhonkrithi monolithic nezakhiwo ufakelo lwesamente. Ezi zinto zisetyenziswa accelerators yokuba lukhuni eziphathekayo. Bona ukwandisa uxhathiso amanzi kwiklasi eziphathekayo, ithanda kwalo ngaphandle kokutshintsha flow (rheology) ngokusetyenziswa plasticizers. Calcium nitrate isetyenziselwa ukwandisa uxhathiso iqabaka eziphathekayo amandla uqhekeke, ukunciphisa shrinkage kunye deformation of nokuqhekeka eziphathekayo, iinkqubo umhlwa kade rebar intsimbi ezisetyenziswa eziphathekayo, ngenxa isiqulatho high chloride.

Ithi isetyenziswe ekulungisweni ukuqinisa, eyenzelwe ukuba nokolula amaqula yeoli, ekulungiseleleni isisombululo zobuchwepheshe ezisetyenziswa lokulungiswa amaqula igesi, kuquka iziselo wokugrumba.

Calcium nitrate lisetyenziswa umdlalo, njengoko yenye izinto abakhoyo neziqhushumbisi. Nakuba kunjalo, isicelo yayo ngenxa hygroscopic eyomeleleyo luthande ukuba nomnyino.

calcium nitrate Iyasetyenziswa kakhulu kwimveliso imichiza, ukuhlanganiswa isakhiwo owomileyo, iiplastiki zeglasi-yomelezwa kunye nezinto zokwakha.
