Cov zaub mov zoo-qib calcium hydroxide
Noj cov calcium hydroxide (calcium cov ntsiab lus ≥ 97%), tseem hu ua hydrated txiv qaub, hydrated txiv qaub.Cim: Dawb hmoov, nrog alkali saj, nrog iab saj, txheeb ze ntom ntom 3.078;Nws tuaj yeem nqus CO₂ los ntawm huab cua thiab hloov mus rau calcium carbonate.Kub kom siab tshaj 100 ℃ kom poob dej thiab tsim cov carbonate zaj duab xis.Tsis tshua muaj insoluble hauv dej, muaj zog alkaline, pH 12.4.Soluble nyob rau hauv saturated daws ntawm glycerol, hydrochloric acid, nitric acid, thiab sucrose, insoluble nyob rau hauv ethanol.
Raws li ib qho tsis, cov neeg nruab nrab, thiab cov neeg ua kom muaj zog, cov zaub mov qib calcium hydroxide kuj tuaj yeem siv rau hauv cov tshuaj, kev sib xyaw ntawm cov khoom noj khoom haus ntxiv, kev sib xyaw ntawm cov khoom siv high-tech biomaterials HA, synthesis ntawm VC phosphate esters li pub additives, thiab cov synthesis ntawm VC phosphate esters. calcium naphthenate, calcium lactate, calcium citrate, additives nyob rau hauv kev lag luam suab thaj, dej kho, thiab high-end organic tshuaj vim nws lub luag hauj lwm nyob rau hauv pH kev cai thiab coagulation.Muab kev pabcuam zoo hauv kev npaj cov tshuaj acidity regulators thiab calcium xws li cov khoom noj khoom haus semi-tiav, konjac khoom, dej haus, tshuaj enemas, thiab lwm yam.
Ntim, cia thiab thauj
Ntim hauv hnab yas woven hnab nrog polyethylene zaj duab xis hnab, nrog ib tug luj ntawm 25kg ib lub hnab.Nws yuav tsum tau muab cia rau hauv ib lub warehouse qhuav.nruj me ntsis tiv thaiv dampness.Tsis txhob co cia thiab thauj nrog cov kua qaub.Thaum lub sij hawm kev thauj mus los, nws yog ib qho tsim nyog los tiv thaiv los nag.Thaum hluav taws tshwm sim, dej, xuab zeb, lossis ib lub tshuab tua hluav taws tuaj yeem siv los tua nws.
1. Koj tuaj yeem paub qhov txawv ntawm Calcium hydroxide los ntawm Calcium oxide li cas?Qhov txawv ntawm lawv yog dab tsi?Qhov twg yuav txawv?
Txog cov lus nug no, peb cov tuam txhab Calcium hydroxide, yuav muab plaub txoj hauv kev zoo rau koj raws li hauv qab no,
1. Muab cov hmoov tso rau hauv lub raj ntsuas, ntxiv cov hmoov carbon ntau dhau, ntsaws lub raj mis lub qhov ncauj nrog ib lub qhov roj hmab ntsaws nrog ib lub raj, thiab muab lub raj mis uas muaj cawv cawv rau ntawm lub qhov ncauj qhov ncauj.
2. Tshav kub ntawm qhov kub siab siv lub tshuab cawv cawv
3.Tom qab txaus cov tshuaj tiv thaiv, nres cua sov.
4. Txias lub raj xa mus rau chav tsev kub, ncuav tawm cov khoom seem, thiab paub qhov txawv xim ntawm cov khoom.
Vim tias CaO + 3C = (siab kub) CaC2 + CO ↑, Ca (OH) 2 tsis hnov tsw nrog C. Carbon yog cov khoom dub, calcium carbide yog grey, xim av daj los yog xim av loj heev, thiab Calcium hydroxide yog dawb. khoom.] Yog tias cov khoom xim yog xim dub thiab dawb, tsuas yog Calcium hydroxide raug pov thawj.
Yog tias cov khoom xim yog xim dub thiab grey, xim av daj lossis xim av, nws ua pov thawj tias tsuas yog Calcium oxide xwb.Yog tias cov khoom xim yog xim dub, dawb, thiab grey, xim av daj, lossis xim av, nws qhia tias muaj kev sib xyaw ntawm ob.
Xaus: Plaub txoj kev saum toj no yog kom paub qhov txawv ntawm Calcium oxide los ntawm Calcium hydroxide.Txoj kev no kuj yooj yim.Cov kws tshaj lij ua cov kws tshaj lij.Yog tias koj xav paub ntau ntxiv, thov xyuam xim rau peb cov chaw tsim khoom Calcium hydroxide.
2.Yuav ua li cas Calcium hydroxide hloov mus ua Calcium oxide?Yuav ua li cas yog Calcium hydroxide los ua Calcium oxide?
Nws yog qhov yooj yim heev rau Calcium hydroxide hloov mus rau hauv Calcium oxide, uas yog ib txoj hauv kev siv tshuaj.Peb cov tuam txhab Calcium hydroxide yuav qhia koj txog qhov no.
Calcium hydroxide yuav tsum tau hnov mob nrog cov pa roj carbon dioxide los tsim cov calcium carbonate, uas tuaj yeem ua kom sov ntawm qhov kub siab los tsim Calcium oxide.
1. Calcium hydroxide reacts nrog carbon dioxide los tsim calcium carbonate los nag thiab dej.
2. Calcium oxide thiab carbon dioxide tuaj yeem tsim los ntawm cua sov calcium carbonate nag lossis daus ntawm qhov kub siab (cua sov rau 900 ℃ ntawm 101.325 kPa).
Kev siv thiab cov khoom ntawm Calcium oxide yog:
1. tuaj yeem siv los ua cov khoom ntim, piv txwv li: ua cov khoom ntim rau epoxy adhesives;
2. Siv los ua cov tshuaj analytical reagent, carbon dioxide absorber rau kev tsom xam roj, spectroscopic tsom xam reagent, high-purity reagent rau epitaxial thiab diffusion txheej txheem nyob rau hauv semiconductor ntau lawm, kuaj ammonia drying, thiab cawv dehydration.
3. Nws tuaj yeem siv los ua cov khoom siv raw los tsim cov calcium carbide, soda tshauv, bleaching hmoov, thiab lwm yam, nrog rau kev ua tawv tawv, kev lim dej pov tseg, Calcium hydroxide thiab ntau yam calcium compounds;
4. tuaj yeem siv los ua cov khoom siv hauv tsev, metallurgical flux, cement accelerator, thiab flux rau fluorescent hmoov;
5. Siv los ua cov nroj tsuag roj decolorizer, tshuaj cab, cov av txias, thiab calcium chiv;
6. Nws kuj tseem siv tau los ua cov khoom siv refractory thiab desiccants;
7. Nws tuaj yeem siv los npaj cov tshuab ua liaj ua teb No.1 thiab No.2 adhesives thiab underwater epoxy adhesives, thiab kuj yog ib qho reactant rau prereaction nrog 2402 resin;
8. Siv rau acidic wastewater kho thiab sludge conditioning;
9. Nws kuj tseem tuaj yeem siv los ua tus neeg saib xyuas kev tiv thaiv rau boiler kaw, siv lub peev xwm nqus dej ntawm cov txiv qaub kom cov hlau nto ntawm boiler dej vapor system kom qhuav thiab tiv thaiv corrosion.Nws yog qhov tsim nyog rau kev tiv thaiv kev kaw lub sijhawm ntev ntawm lub zog qis, nruab nrab siab, thiab lub peev xwm me me nruas boilers;
10. Calcium oxide yog ib qho yooj yim oxide, uas yog rhiab heev rau cov av noo.Yooj yim kom nqus cov pa roj carbon dioxide thiab dej los ntawm huab cua.Nws tuaj yeem hnov mob nrog dej los npaj Calcium hydroxide, uas belongs rau Combination cov tshuaj tiv thaiv.
