Chakudya chapamwamba kwambiri cha calcium hydroxide
edible calcium hydroxide (calcium content ≥ 97%), yomwe imadziwikanso kuti hydrated laimu, hydrated laimu.Khalidwe: ufa woyera, ndi kukoma kwa alkali, ndi kukoma kowawa, kachulukidwe wachibale 3.078;Imatha kuyamwa CO₂ mumlengalenga ndikuisintha kukhala calcium carbonate.Kutenthetsa pamwamba pa 100 ℃ kuti mutaya madzi ndikupanga filimu ya carbonate.Zosasungunuka kwambiri m'madzi, zamchere kwambiri, pH 12.4.Amasungunuka muzitsulo zodzaza za glycerol, hydrochloric acid, nitric acid, ndi sucrose, osasungunuka mu ethanol.
Monga chotchinga, neutralizer, ndi solidifying wothandizira, chakudya kalasi calcium hydroxide angagwiritsidwenso ntchito mankhwala, kaphatikizidwe zakudya zina, kaphatikizidwe apamwamba chatekinoloje biomaterials HA, kaphatikizidwe wa VC phosphate esters monga zowonjezera chakudya, ndi kaphatikizidwe wa calcium naphthenate, calcium lactate, calcium citrate, zowonjezera m'makampani a shuga, chithandizo chamadzi, ndi mankhwala apamwamba kwambiri achilengedwe chifukwa cha gawo lake pakuwongolera pH ndi kukhazikika.Perekani thandizo logwira mtima pokonzekera zowongolera acidity ndi magwero a calcium monga zinthu zomalizidwa pang'ono, zinthu za konjac, zakumwa, ma enemas amankhwala, etc.
Kuyika, kusunga ndi zoyendera
Ankalongedza mu matumba apulasitiki nsalu alimbane ndi polyethylene filimu matumba, ndi ukonde kulemera kwa 25kg pa thumba.Iyenera kusungidwa m'nyumba yosungiramo zinthu zouma.Kupewa kwambiri chinyontho.Pewani kusungirako zinthu limodzi ndi kusuntha ndi ma asidi.Panthawi yoyendetsa, ndikofunikira kupewa mvula.Moto ukayaka, madzi, mchenga, kapena chozimitsira moto wamba kuti auzimitse.
1. Kodi mungasiyanitse bwanji Calcium hydroxide ndi Calcium oxide?Kodi njira yowasiyanitsa ndi yotani?Kuti tisiyanitse?
Za mafunso amenewo, ife opanga Calcium hydroxide, tikupatsani njira zinayi zabwino motere,
1. Ikani ufa mu chubu choyesera, onjezerani ufa wochuluka wa carbon, sungani pakamwa pa botolo ndi pulagi ya rabara ya bowo limodzi ndi chubu, ndipo ikani botolo lamoto woyaka Mowa pakamwa pa chubu chotulutsa mpweya.
2. Kutenthetsa kutentha kwambiri pogwiritsa ntchito choyatsira mowa
3.Atachita mokwanira, siyani kutentha.
4. Kuziziritsa chubu choyesera kutentha kutentha, kutsanulira zolimba zotsalira, ndi kusiyanitsa mtundu wa mankhwala.
Chifukwa CaO+3C=(kutentha kwapamwamba) CaC2+CO ↑, Ca (OH) 2 samachita ndi C. Carbon ndi yolimba yakuda, calcium carbide ndi imvi, yofiirira yachikasu kapena yofiirira, ndipo Calcium hydroxide ndi yoyera. olimba.]Ngati mtundu wa chinthucho ndi wakuda ndi woyera, Calcium hydroxide yokha ndiyomwe imatsimikiziridwa.
Ngati mtundu wa mankhwala ndi wakuda ndi imvi, bulauni wachikasu kapena bulauni, zimatsimikizira kuti pali Calcium oxide yokha.Ngati mtundu wa mankhwala ndi wakuda, woyera, ndi imvi, bulauni wachikasu, kapena bulauni, umasonyeza kusakaniza kwa ziwirizo.
Kutsiliza: Njira zinayi zomwe tatchulazi ndi zosiyanitsa Calcium oxide ndi Calcium hydroxide.Njirayi ndi yosavuta.Akatswiri amachita zinthu mwaukadaulo.Ngati mukufuna kudziwa zambiri, chonde tcherani khutu kwa wopanga Calcium hydroxide.
2.Kodi Calcium hydroxide ingasinthe bwanji kukhala Calcium oxide?Kodi njira yopangira Calcium hydroxide kukhala Calcium oxide ndi iti?
Ndizosavuta kuti Calcium hydroxide isinthe kukhala Calcium oxide, yomwe ndi njira yodziwika bwino yamankhwala.Ife opanga Calcium hydroxide tidzakuuzani za izi.
Calcium hydroxide imayenera kuchitapo kanthu ndi carbon dioxide kuti ipange calcium carbonate, yomwe imatha kutentha kutentha kwambiri kuti ipange Calcium oxide.
1. Calcium hydroxide imakumana ndi mpweya woipa kupanga calcium carbonate mvula ndi madzi.
2. Calcium oxide ndi carbon dioxide akhoza kupangidwa ndi kutentha kwa mpweya wa calcium carbonate pa kutentha kwakukulu (kutentha kwa 900 ℃ pa 101.325 kPa).
Ntchito ndi katundu wa Calcium oxide ndi:
1. Ikhoza kugwiritsidwa ntchito ngati chodzaza, mwachitsanzo: monga chodzaza ndi zomatira za epoxy;
2. Amagwiritsidwa ntchito ngati reagent analytical, carbon dioxide absorber pofuna kusanthula gasi, spectroscopic analysis reagent, high-purity reagent for epitaxial and diffusion process in semiconductor production, laboratory ammonia kuyanika, ndi kutaya madzi m'thupi.
3. Ikhoza kugwiritsidwa ntchito ngati zopangira kupanga calcium carbide, phulusa la soda, bleaching powder, etc., komanso kupanga zikopa, kuyeretsa madzi onyansa, Calcium hydroxide ndi mankhwala osiyanasiyana a calcium;
4. Itha kugwiritsidwa ntchito ngati zomangira, zitsulo zachitsulo, accelerator simenti, ndi flux ya fulorosenti ufa;
5. Amagwiritsidwa ntchito ngati chomera mafuta decolorizer, chonyamulira mankhwala, conditioner nthaka, ndi calcium fetereza;
6. Ikhoza kugwiritsidwanso ntchito ngati zipangizo zokanira ndi desiccants;
7. Angagwiritsidwe ntchito pokonzekera makina ulimi No.1 ndi No.2 zomatira ndi madzi epoxy zomatira, komanso monga reactant kwa prereaction ndi 2402 utomoni;
8. Amagwiritsidwa ntchito popangira madzi otayira acidic komanso kukonza matope;
9. Itha kugwiritsidwanso ntchito ngati chotchinga chotchinga chotseka chotenthetsera, kugwiritsa ntchito mphamvu yoyamwa chinyezi cha laimu kuti chitsulo chizikhala chouma komanso kupewa dzimbiri.Ndikoyenera kutetezedwa kwa nthawi yayitali kutsekeka kwapang'onopang'ono, kuthamanga kwapakatikati, ndi ma boiler ang'onoang'ono ang'oma;
10. Calcium oxide ndi Basic oxide, yomwe imakhudzidwa ndi chinyezi.Mosavuta kuyamwa mpweya woipa ndi madzi kuchokera mumlengalenga.Itha kuchitapo kanthu ndi madzi kukonza Calcium hydroxide, yomwe ndi ya Combination reaction.
