Umgangatho ophezulu wokutya we-calcium hydroxide
I-calcium hydroxide etyiwayo (i-calcium content ≥ 97%), eyaziwa ngokuba yi-hydrated lime, i-hydrated lime.Umlingiswa: Umgubo omhlophe, kunye nencasa ye-alkali, kunye nencasa ekrakra, ukuxinana kwe-3.078;Iyakwazi ukufunxa i-CO₂ emoyeni kwaye iyiguqule ibe yi-calcium carbonate.Fudumeza ukuya kuthi ga kwi-100 ℃ ukuze ulahlekelwe ngamanzi kwaye wenze ifilimu yecarbonate.Inganyibiliki kakhulu emanzini, i-alkaline enamandla, i-pH 12.4.I-Soluble kwi-saturated solutions ye-glycerol, i-hydrochloric acid, i-nitric acid, kunye ne-sucrose, enganyibilikiyo kwi-ethanol.
Njenge-buffer, neutralizer, kunye ne-ejenti yokuqinisa, ibakala lokutya i-calcium hydroxide inokusetyenziswa kwezamayeza, i-synthesis yezongezo zokutya, i-synthesis ye-high-tech biomaterials HA, i-synthesis ye-VC phosphate esters njengezongezo zokutya, kunye nokudibanisa i-calcium naphthenate, i-calcium lactate, i-calcium citrate, izongezo kwishishini leswekile, unyango lwamanzi, kunye neekhemikhali eziphezulu ze-organic ngenxa yendima yayo ekulawuleni i-pH kunye ne-coagulation.Ukubonelela ngoncedo olusebenzayo ekulungiseleleni abalawuli be-asidi kunye nemithombo ye-calcium efana neemveliso ezidliwayo ezigqityiweyo, iimveliso ze-konjac, iimveliso zesiselo, i-enemas yamachiza, njl.
Ukupakishwa, ukugcinwa kunye nokuthutha
Ipakishwe kwiiplastiki ezilukiweyo ezifakwe kwiingxowa zefilimu ezine-polyethylene, ezinobunzima obungama-25kg kwingxowa nganye.Kufuneka igcinwe kwindawo yokugcina impahla eyomileyo.Ukuthintela ngokungqongqo ukufuma.Gwema ukugcinwa ngokubambisana kunye nokuthutha ngee-asidi.Ngexesha lokuthutha, kuyimfuneko ukukhusela imvula.Xa kuvela umlilo, kunokusetyenziswa amanzi, isanti, okanye isixhobo esiqhelekileyo sokucima umlilo ukuze siwucime.
1. Ungayahlula njani iCalcium hydroxide kwiCalcium oxide?Ithini indlela yokuzahlula?Ukwahlula phi?
Malunga naloo mibuzo, thina bavelisi beCalcium hydroxide, siya kukunika iindlela ezine ezilungileyo ngolu hlobo lulandelayo,
1. Faka umgubo kwityhubhu yokuvavanya, yongeza umgubo wekhabhoni ogqithisileyo, uvale umlomo webhotile ngeplagi yerabha yomngxuma omnye ngombhobho, kwaye ubeke ibhotile yesitshisi sotywala emlonyeni wetyhubhu yokukhupha.
2. Fudumeza kwiqondo lobushushu eliphezulu usebenzisa isitovu sotywala
3.Emva kokusabela okwaneleyo, yeka ukufudumeza.
4. Pholisa ityhubhu yokuvavanya kwiqondo lokushisa, uthele i-solids eseleyo, kwaye uhlukanise umbala wemveliso.
Ngenxa yokuba iCaO+3C=(ubushushu obuphezulu) CaC2+CO ↑, Ca (OH) 2 ayisebenzi ngeC. Ikhabhoni yinto eqinileyo emnyama, icalcium carbide yingwevu, imdaka emthubi okanye imdaka ngebala, kwaye iCalcium hydroxide imhlophe. okuqinileyo.]Ukuba umbala wemveliso umnyama namhlophe, yiCalcium hydroxide kuphela eqinisekisiweyo.
Ukuba umbala wemveliso umnyama kunye negrey, umdaka otyheli okanye omdaka, ubonisa ukuba kukho iCalcium oxide kuphela.Ukuba umbala wemveliso umnyama, umhlophe, ungwevu, umthubi omdaka, okanye umdaka, ubonisa umxube wezo zimbini.
Isiphelo: Ezi ndlela zine zingentla zezokwahlula iCalcium oxide kwiCalcium hydroxide.Indlela ilula noko.Abantu abaziingcali benza izinto zobuchwephesha.Ukuba ufuna ukwazi ngakumbi, nceda uqaphele umenzi wethu weCalcium hydroxide.
2.Ingaguqulwa njani iCalcium hydroxide ibe yiCalcium oxide?Yeyiphi indlela yokuba iCalcium hydroxide ibe yiCalcium oxide?
Kulula kakhulu ukuba iCalcium hydroxide iguqulwe ibe yiCalcium oxide, yindlela eqhelekileyo yeekhemikhali.Thina abavelisi beCalcium hydroxide siya kukuxelela malunga noku.
I-calcium hydroxide kufuneka idibane ne-carbon dioxide ukuze ivelise i-calcium carbonate, enokufudunyezwa kubushushu obuphezulu ukuvelisa i-Calcium oxide.
1. I-calcium hydroxide idibana ne-carbon dioxide ukuze yenze imvula ye-calcium carbonate kunye namanzi.
2. I-calcium oxide kunye ne-carbon dioxide inokuveliswa ngokufudumeza i-calcium carbonate precipitation kwiqondo lokushisa eliphezulu (ukufudumala kwi-900 ℃ kwi-101.325 kPa).
Ukusetyenziswa kunye neempawu zeCalcium oxide zezi:
1. Ingasetyenziswa njenge-filler, umzekelo: njenge-filler ye-epoxy adhesives;
2. Isetyenziswe njenge-reagent analytical, i-carbon dioxide absorber kuhlalutyo lwegesi, i-spectroscopic analysis reagent, i-high-purity reagent ye-epitaxial kunye ne-diffusion iinkqubo kwimveliso ye-semiconductor, i-laboratory ammonia drying, kunye nokuchithwa kotywala.
3. Ingasetyenziselwa njengento eluhlaza ukuvelisa i-calcium carbide, i-soda ash, i-bleaching powder, njl., kunye nokwenziwa kwesikhumba, ukuhlanjululwa kwamanzi amdaka, i-Calcium hydroxide kunye neentlobo ezahlukeneyo ze-calcium;
4. Ingasetyenziswa njengesixhobo sokwakha, i-metallurgical flux, i-cement accelerator, kunye ne-flux ye-fluorescent powder;
5. Isetyenziswe njenge-decolorizer ye-oyile yesityalo, i-oil carrier, i-conditioner yomhlaba, kunye nesichumisi se-calcium;
6. Inokusetyenziswa kwakhona njengezinto eziphikisayo kunye ne-desiccants;
7. Ingasetyenziselwa ukulungiselela oomatshini bezolimo No.1 kunye neNo.2 yokuncamathelisa kunye ne-adhesives epoxy engaphantsi kwamanzi, kunye ne-reactant yokusabela kwangaphambili nge-resin ye-2402;
8. Isetyenziselwa ukucocwa kwamanzi amdaka aneasidi kunye nokulungiswa kodaka;
9. Isenokusetyenziswa njengesixhobo sokukhusela ukuvala kwibhoyila, kusetyenziswa isakhono sokufunxa ukufuma kwekalika ukugcina umphezulu wesinyithi webhoyila inkqubo yomphunga wamanzi womile kwaye uthintele ukuhlwa.Kufanelekile ukukhuselwa kwexesha elide lokuvalwa koxinzelelo oluphantsi, uxinzelelo oluphakathi, kunye nomthamo omncinci webhoilers;
10. I-calcium oxide yi-Basic oxide, evakalelwa kukufuma.Kulula ukufunxa ikharbon diokside kunye namanzi emoyeni.Inokusabela ngamanzi ukulungiselela iCalcium hydroxide, eyeyeNdibaniselwano yokusabela.
