Calcium nitrate. Izakhiwo kanye Izicelo

calcium nitrate, eyaziwa nangokuthi amagama wendabuko "calcium nitrate" "lime noma calcium nitrate" kuyinto usawoti wezinto ezingaphili ka nitric acid kuyinto cubic zinhlayiya kungekho nto enemibala emihle. Egcekeni kuyinto hygroscopic kakhulu. kwakwakhe Wugqinsi - 2.36 g / cm³, lokushisa ukuncibilika - 561 ° C, abilayo iphuzu - 151 ° C. Ngaphansi kwezimo ezivamile wesitoreji akunakudluliswa oluvuthayo impahla non-eziyiziqhumane. Esikhathini lokushisa ububanzi -60 ° C - +155 ° C ukuzinza kubonakala lapho ihlukanisa calcium nitrate. Formula chemical kwakwakhe - Ca (NO3) 2.

Calcium nitrate lalungiselela ukumuncwa nitrogen oxides ne nobisi lime noma HNO3 ithonya namathempeli ngokhonkolo namatshe. I granulated calcium nitrate ezihlelwa indlela ephansi lokushisa neutralization HNO3 limestone zemvelo.

calcium nitrate - jikelele bokuphila ane-alikhali Umanyolo, efanelekayo nenhlabathi nge ongaphakeme calcium okuqukethwe. Calcium nitrate kufanelekile bonke nenhlabathi. ezifanele ikakhulukazi uhlelo lwayo lokusebenza acidified, isihlabathi, nenhlabathi alikhali. Calcium kabanti kubalulekile ekutfutfukiseni enempilo nelungile isitshalo kwezicubu, okwandisa ngamandla abo iseli izindonga, ukwenza ngcono ikhwalithi yokubandula izithelo. Calcium nitrate ngcono kwekhono of imikhiqizo, yelula ukuphila eshalofini. Iphinde isetshenziselwe ukuvimbela izifo cuphuluza calcium ukuntula (core noma bola apical, leaf onqenqemeni kuvuthe futhi abanye). Umanyolo sisetshenziswa ewuketshezi. Ukuze izinhlelo hydroponic calcium nitrate - indlela kuphela ukuthola i-calcium lapho ifakwa emanzini.

Ukulungiselela compounds ngesimo granules kanye amakristalu kakhulu titfutfukiswe kwenkululeko uhlelo lwayo lokusebenza. Granulated calcium nitrate kungaqali ikhekhe, hhayi hygroscopic, kulula ukuyisebenzisa.

Crystalline calcium nitrate kabanzi lisetshenziswe wokwakha umkhakha. Kuyinto okufakiwe eziyinkimbinkimbi busuka eziphathekako izigqulo ukuze sithuthukise izindawo zabo ukwakhiwa ngokhonkolo Monolithic futhi wasisekela izakhiwo zikakhonkolo. Lezi zinto zehlela ezisetshenziswa njengeziwusizo accelerators ka lukhuni ukhonkolo. Bona ukwandisa ukumelana amanzi ekilasini ukhonkolo, kwelula sekushoneni kwalo ngaphandle kokushintsha ukugeleza (rheology) ngokusebenzisa plasticizers. Calcium nitrate isetshenziswa ukwandisa ukumelana frost wamandla ukhonkolo sekungaphezu kwamandla ethu, ukunciphisa ukuncipha futhi ukusonteka of kwemifantu ukhonkolo, kancane ukugqwala izinqubo rebar steel esetshenziswa ukhonkolo, ngenxa eliphezulu okuqukethwe chloride.

Iphinde isetshenziselwe ekulungiseleleni ukuqinisa, okuyinto zenzelwe ekuqiniseni kwemithombo uwoyela, ekulungiseleleni isixazululo zobuchwepheshe asetshenziswe ukukhanda igesi emithonjeni, kuhlanganise imishini eziwuketshezi.

Calcium nitrate isetshenziswa pyrotechnics, njengoba ingenye izakhi abamelwe iziqhumane. Nokho, uhlelo lwayo lokusebenza ngenxa hygroscopic eqinile ukuyaphi.

calcium nitrate Liphinde kabanzi ukukhiqizwa amakhemikhali, ezomile isakhiwo amamiksi, epulasitikini ingilazi-kwagcizelela nasezintweni zokwakha.
