Imikhiqizo
Ikhwalithi ephezulu yezinga lokudla i-calcium hydroxide
I-calcium hydroxide edliwayo (okuqukethwe kwe-calcium ≥ 97%), eyaziwa nangokuthi i-hydrated lime, i-hydrated lime.Uhlamvu: Impushana emhlophe, enokunambitheka kwe-alkali, enokunambitheka okubabayo, ukuminyana kwesihlobo 3.078;Ingakwazi ukumunca i-CO₂ emoyeni futhi iyiguqule ibe yi-calcium carbonate.Shisisa ngaphezu kuka-100 ℃ ukuze ulahlekelwe amanzi futhi wenze ifilimu ye-carbonate.Ayincibiliki kakhulu emanzini, i-alkaline enamandla, i-pH 12.4.Incibilika ezixazululweni ezigcwele ze-glycerol, i-hydrochloric acid, i-nitric acid, ne-sucrose, engancibiliki ku-ethanol.
Njenge-buffer, neutralizer, kanye ne-ejenti eqinisayo, i-calcium hydroxide yebanga lokudla ingasetshenziswa futhi kwezokwelapha, ukuhlanganiswa kwezithasiselo zokudla, ukuhlanganiswa kwe-high-tech biomaterials HA, ukuhlanganiswa kwe-VC phosphate esters njengezithasiselo zokudla, kanye nokuhlanganiswa kwe i-calcium naphthenate, i-calcium lactate, i-calcium citrate, izithasiselo embonini kashukela, ukwelashwa kwamanzi, namakhemikhali aphilayo asezingeni eliphezulu ngenxa yendima yawo ekulawuleni i-pH kanye nokuhlangana.Nikeza ngosizo olusebenzayo ekulungiseleleni izilawuli ze-acidity nemithombo ye-calcium njengemikhiqizo edliwayo eqedwe kancane, imikhiqizo ye-konjac, imikhiqizo yesiphuzo, ama-enema emithi, njll.
Ukupakisha, ukugcinwa kanye nezokuthutha
Ipakishwe ngezikhwama zepulasitiki ezilukiwe ezifakwe izikhwama zefilimu ye-polyethylene, enesisindo esinetha esingu-25kg isikhwama ngasinye.Kufanele igcinwe endaweni eyomile.Vimbela ngokuqinile umswakama.Gwema ukugcinwa ndawonye nokuthutha ngama-asidi.Ngesikhathi sokuthutha, kuyadingeka ukuvimbela imvula.Lapho kuvela umlilo, kungasetshenziswa amanzi, isihlabathi, noma isicisha-mlilo esivamile ukuze ucime.
1. Ungayihlukanisa kanjani iCalcium hydroxide kuCalcium oxide?Iyiphi indlela yokuwahlukanisa?Ukuhlukanisa kuphi?
Mayelana naleyo mibuzo, thina abakhiqizi beCalcium hydroxide, sizokunikeza izindlela ezine ezinhle ngale ndlela elandelayo,
1. Faka impushana eshubhuni yokuhlola, engeza impushana yekhabhoni eyeqile, uxhume umlomo webhodlela ngepulaki yenjoloba eyimbobo eyodwa ngeshubhu, bese ubeka ibhodlela lesishisi sotshwala emlonyeni weshubhu lokukhipha umoya.
2. Shisisa ezingeni lokushisa eliphezulu usebenzisa isishisi sotshwala
3.Ngemva kokusabela okwanele, yeka ukushisa.
4. Pholisa ishubhu lokuhlola ekamelweni lokushisa, uthele okuqinile okusele, futhi uhlukanise umbala womkhiqizo.
Ngoba i-CaO+3C=(izinga lokushisa eliphakeme) i-CaC2+CO ↑, i-Ca (OH) 2 ayisabelani ne-C. Ikhabhoni iqinile elimnyama, i-calcium carbide iqinile ngokumpunga, okuphuzi okunsundu noma okunsundu, kanti i-Calcium hydroxide imhlophe. okuqinile.]Uma umbala womkhiqizo umnyama nomhlophe, i-Calcium hydroxide kuphela efakazelwayo.
Uma umbala womkhiqizo umnyama futhi umpunga, onsundu ophuzi noma onsundu, kufakazela ukuthi kukhona i-Calcium oxide kuphela.Uma umbala womkhiqizo umnyama, umhlophe, nompunga, ophuzi onsundu, noma onsundu, ukhombisa ingxube yalokhu okubili.
Isiphetho: Izindlela ezine ezingenhla ukuhlukanisa iCalcium oxide neCalcium hydroxide.Indlela ilula uma kuqhathaniswa.Abantu abangochwepheshe benza izinto zobungcweti.Uma ufuna ukwazi okwengeziwe, sicela unake umkhiqizi wethu weCalcium hydroxide.
2.Ingaguqulwa kanjani iCalcium hydroxide ibe yiCalcium oxide?Iyiphi indlela yokuthi iCalcium hydroxide ibe iCalcium oxide?
Kulula kakhulu ukuthi iCalcium hydroxide iguqulwe ibe yiCalcium oxide, okuyindlela ejwayelekile yamakhemikhali.Thina abakhiqizi beCalcium hydroxide sizokutshela ngalokhu.
I-calcium hydroxide idinga ukusabela ne-carbon dioxide ukuze ikhiqize i-calcium carbonate, engashiswa ezingeni lokushisa eliphezulu ukuze ikhiqize i-Calcium oxide.
1. I-calcium hydroxide ihlangana ne-carbon dioxide yakhe imvula ye-calcium carbonate namanzi.
2. I-calcium oxide ne-carbon dioxide ingakhiqizwa ngokushisisa imvula ye-calcium carbonate ezingeni lokushisa eliphezulu (ukushisa kufika ku-900 ℃ ku-101.325 kPa).
Ukusetshenziswa kanye nezakhiwo zeCalcium oxide yilezi:
1. Ingasetshenziswa njenge-filler, isibonelo: njenge-filler ye-epoxy adhesives;
2. Isetshenziswa njenge-reagent yokuhlaziya, i-carbon dioxide absorber yokuhlaziya igesi, i-spectroscopic analysis reagent, i-high-purity reagent yezinqubo ze-epitaxial kanye ne-diffusion ekukhiqizeni kwe-semiconductor, ukomiswa kwe-ammonia elabhorethri, kanye nokuphelelwa amandla kwamanzi otshwala.
3. Ingasetshenziswa njengento eluhlaza ukukhiqiza i-calcium carbide, i-soda ash, i-bleaching powder, njll., kanye nokwenza isikhumba, ukuhlanzwa kwamanzi angcolile, i-Calcium hydroxide kanye nezinhlanganisela ezihlukahlukene ze-calcium;
4. Ingasetshenziswa njengempahla yokwakha, i-metallurgical flux, i-accelerator kasimende, kanye ne-flux ye-fluorescent powder;
5. Isetshenziswa njenge-decolorizer kawoyela wezitshalo, umthwali wezidakamizwa, i-conditioner yenhlabathi, kanye nomanyolo we-calcium;
6. Ingasetshenziswa futhi njengezinto eziphikisayo kanye nama-desiccants;
7. Ingasetshenziswa ukulungisa imishini yezolimo No.1 kanye ne-No.2 adhesives kanye ne-epoxy adhesives engaphansi kwamanzi, futhi njenge-reactant for prereaction ne-2402 resin;
8. Isetshenziselwa ukuhlanza amanzi angcolile ane-asidi kanye nokulungisa udaka;
9. Ingasetshenziswa futhi njengesivikelo sokuvala ubhayela, isebenzisa ikhono lokumunca umswakama womcako ukuze igcine ingaphezulu lensimbi lesistimu yomhwamuko wamanzi kubhayela yomile futhi ivimbele ukugqwala.Ifanele ukuvikelwa kokuvala isikhathi eside kokucindezela okuphansi, ukucindezela okuphakathi, kanye nama-boilers emigqomo emincane;
10. I-calcium oxide iyi-Basic oxide, ezwelayo kumswakama.Kulula ukumunca i-carbon dioxide namanzi emoyeni.Ingasabela ngamanzi ukuze ilungise i-Calcium hydroxide, eyingxenye ye-Combination reaction.
