Kalisiyumu ikoreshwa

Kalisiyumu ikora: ubwoko bwose bwumye buvanze, ubwoko bwose bwa beto, ibikoresho birwanya kwambara, inganda zo hasi, inganda zigaburira, gutunganya. Ingano ya calcium ikora ni 0.5 ~ 1.0% kuri toni ya minisiteri yumye na beto, kandi umubare wongeyeho ni 2.5%. Ingano ya calcium ikora yiyongera buhoro buhoro hamwe no kugabanuka kwubushyuhe, kandi niyo umubare wa 0.3-0.5% ushyirwa mugihe cyizuba, bizagira ingaruka zikomeye zambere.
Kalisiyumu ikora ni hygroscopique kandi iryoshye gato. Ntaho ibogamiye, idafite uburozi, gushonga mumazi. Igisubizo cyamazi ntaho kibogamiye. Ububasha bwa calcium ya calcium ntabwo ihinduka cyane hamwe no kwiyongera kwubushyuhe, amazi 16g / 100g kuri 0 ℃ na 18.4g / 100g amazi kuri 100 ℃. Uburemere bwihariye: 2.023 (20 ℃), ubwinshi bwinshi 900-1000g / L. Ubushyuhe bwo kubora> 400 ℃.
Mu bwubatsi, ikoreshwa nkibikoresho byihuse, amavuta yo kwisiga hamwe nimbaraga za kare kuri sima. Byakoreshejwe mukubaka minisiteri na beto zitandukanye, kwihutisha umuvuduko ukabije wa sima, gabanya igihe cyagenwe, cyane cyane mubwubatsi bwubukonje, kugirango wirinde ubushyuhe buke bwo gushiraho buhoro buhoro. Kwihuta cyane, kugirango sima byihuse kugirango utezimbere imbaraga zikoreshwa.
Acide ya formique itabangamiwe na lime hydrated kugirango itange calcium, kandi calcium yubucuruzi iboneka mugutunganya. Sodium ikora na nitrate ya calcium ikora reaction ebyiri zibora imbere ya catalizator kugirango ibone calcium kandi ifatanye na nitrate ya sodium. Ubucuruzi bwa calcium yubucuruzi yabonetse mugutunganya.
Mubikorwa byo kubyara pentaerythritol, hydroxide ya calcium ikoreshwa mugutanga ibintu byibanze byifata, kandi calcium ya calcium ikorwa hongerwamo aside aside na hydroxide ya calcium mugihe cyo kutabogama.
Anhydrous formic aside irashobora kuboneka mukuvanga acide formic na fosifore pentoxide hamwe na distillation mugihe cyumuvuduko ukabije, bigasubirwamo inshuro 5 kugeza 10, ariko amafaranga ni make kandi atwara igihe, bizatera kubora. Gutandukanya aside irike na aside ya boric biroroshye kandi bifite akamaro. Acide ya boric idafite umwuma mubushyuhe bwo hejuru kugeza igihe itagikora ibibyimba byinshi, hanyuma ibivuyemo bigasukwa kumpapuro yicyuma, bikonjeshwa mukuma, hanyuma bigahinduka ifu.
Ifu nziza ya borate fenol yongewe kuri acide formique hanyuma ishyirwa muminsi mike kugirango ikore misa ikomeye. Amazi asukuye yatandukanijwe kugirango avunagurwe kandi igice cyo gutandukanya 22-25 ℃ / 12-18 mm cyegeranijwe nkibicuruzwa. Ibisigaye bigomba kuba byuzuye hamwe kandi bikarindwa numuyoboro wumye.
Ubike mu bubiko bukonje, buhumeka. Irinde umuriro n'ubushyuhe. Ubushyuhe bwikigega ntibushobora kurenga 30 and, nubushuhe bugereranije ntibushobora kurenga 85%. Komeza ikintu. Igomba kubikwa ukwayo na okiside, alkalis nifu yifu yicyuma, kandi ntigomba kuvangwa. Bifite ibikoresho bitandukanye hamwe nubunini bwibikoresho byumuriro. Ahantu ho guhunika hagomba kuba hafite ibikoresho byo kuvura byihutirwa nibikoresho bikwiye.
