Hnyav calcium, tseem hu ua av calcium carbonate.Nws yog ib qho inorganic compound ua los ntawm calcite, marble, limestone thiab lwm yam ore raw cov ntaub ntawv los ntawm kev sib tsoo nrog ib tughnyavcalcium sib tsoo zeb.Yog li, qhov sib txawv ntawm cov calcium hnyav uas tsim los ntawm cov ntaub ntawv ore no yog dab tsi?HCMilling (Guilin Hongcheng), raws li cov chaw tsim khoom ntawm lubhnyavcalcium sib tsoo zeb uas tau koom nrog kev lag luam calcium carbonate tau ntau xyoo, tsimCalcium carbonate Raymond zeb, calcium carbonateultra-zoo nplhaib roller mills, calcium carbonatesuperzoontsug roller mills thiab lwm yam khoom siv.Cov hauv qab no piav qhia txog qhov sib txawv ntawm kev tsim cov calcium hnyav, calcite, marble thiab limestone.

1,Contrast calcite, marble, limestone

Calcite: cov ore muaj qhov tseeb cleavage thiab pob tshab.Qhov saum npoo tau muab faib ua cov dav hlau ntshiab, uas tseem pom tom qab crushing.Calcite mining cheeb tsam yog dav faib, thiab ores kuj muab faib ua calcite loj thiab me me calcite.Cov calcite loj muaj qhov tseeb cleavage, tsis tu ncua thiab siab pob tshab;Lub calcite cleavage yog tsis meej, zoo thiab tsis xwm yeem.Nws yuav tsum tau muab sau tseg tias muaj peb xim ntawm calcite ore, uas yog, milky dawb theem, yellowish theem thiab reddish theem.Tej zaum yuav muaj qhov sib txawv ntawm cov xim ntawm txhua qhov chaw tsim khoom, thiab tej zaum yuav muaj qee qhov sib txawv ntawm cov khoom siv kho qhov muag ntawm cov txheej txheem calcium carbonate hmoov.Tsis tas li ntawd, cov ntsiab lus calcium ntawm calcite yog siab dua li ntawm marble thiab limestone, ncav cuag ntau dua 99%.Feem ntau ntawm cov hlau impurities yog Fe, Mn, Cu, thiab lwm yam. Cov txheeb ze ntom yog 2.5 ~ 2.9 g / cm3, thiab Mohs hardness yog 2.7 ~ 3.0.

Marble: tseem hu ua dolomite, nws yog tsim los ntawm calcite, limestone, serpentine thiab dolomite.Ntawm lawv, muaj pes tsawg leeg ntawm calcium carbonate account rau ntau tshaj 95%, Mohs hardness nyob nruab nrab ntawm 2.5-5, thiab qhov ceev yog 2.6 mus rau 2.8g / cm³.,Cov ore tau muab faib ua ntxhib siv lead ua ore thiab zoo siv lead ua ore, thiab cov siv lead ua feem ntau yog cubic.Lub suab marble feem ntau yog xiav (grey) dawb, thiab cov ntsiab lus ntawm impurities xws li magnesium oxide (0.2% ~ 0.7%), ferric oxide (<0.08%), manganese (1 ~ 50mg / kg) txawv txav nyob ntawm lub hauv paus chiv keeb. .

Limestone: Limestone yog ib hom pob zeb uas muaj ib qho calcite ntxhia muaj pes tsawg leeg, uas yog kev sib xyaw ua ke ntawm cov khoom zoo los yog aphanitic.Nws muaj nyob rau hauv ob theem ntawm calcite thiab aragonite, thiab yog nkig thiab ntom.Limestone muaj ntau dua 95% calcium carbonate, ib qho me me ntawm dolomite, siderite, quartz, feldspar, mica thiab av nplaum ntxhia uas tuaj yeem cuam tshuam cov xim ntawm pob zeb, feem ntau yog dawb thiab grey.Lub ntsiab impurities ntawm limestone muaj xws li silicon dioxide, txhuas oxide, hlau oxide, magnesium, strontium, thiab lwm yam Mohs hardness yog 3.5 ~ 4, thiab qhov ceev yog 2.7 g / cm3.

2,Kev siv sib txawv ntawm calcite, marble thiab limestone

Plastics: Marble thiab calcite tau dav siv, tab sis calcite thiab marble muaj xim sib txawv thiab cov qauv siv lead ua.Cov xim, tensile quab yuam thiab cuam tshuam tsis kam ntawm cov khoom ntim hauv cov khoom yas yuav txawv rau qee qhov.Calcite belongs rau hexagonal crystal system, thiab cov siv lead ua feem ntau nyob rau hauv cov duab ntawm hnub nucleus, nrog rau qhov loj piv ntawm ntev mus rau luv luv diameters;Marble muaju feem ntau yog cubic nyob rau hauv cov duab, nrog ib tug me me piv ntawm ntev mus rau luv diameters.Cov khoom xws li cov kav dej PVC thiab cov ntaub ntawv muaj cov calcite thiab marble nrog tib qhov loj me me faib raws li cov qauv tib yam.Cov khoom ua los ntawm marble hmoov yog yooj yim rau nkig tshaj li cov khoom ua los ntawm calcite hmoov, thiab lub toughness yog tsis zoo.

Papermaking: calcite thiab marble uas tsis tshua muaj hardness thiab softer zoo yog xaiv raws li hnyav calcium carbonate raw cov ntaub ntawv, uas muaj tsawg coj tus nqi ntawm cov khoom, thiab yog zoo rau kev tiv thaiv thiab ncua lub neej ntawm lim tshuaj ntsuam, cutter taub hau thiab lwm yam ntawm daim ntawv tshuab.

Latex xim: muaj pes tsawg leeg ntawm calcium carbonate raw ores txawv heev.Feem ntau, purity ntawm calcite ore yog siab, cov ntsiab lus calcium carbonate yog ntau tshaj 96%, thiab cov ntsiab lus ntawm impurities xws li magnesium oxide thiab ferric oxide yog tsawg los yog yooj yim tshem tawm, yog li cov xim latex ruaj khov dua.

HCMilling (Guilin Hongcheng), raws li calcium carbonate kev lag luam saw, tau muab cov cuab yeej zoo txhawb rau calcium hmoov ua lag luam thoob ntiaj teb.PebCalcium carbonate Raymond zeb, calcium carbonate ultra-zoonplhaib roller mills, calcium carbonatesuperzoontsug roller mills thiab lwm cov khoom siv calcium hnyav hnyav kuj tau txais txiaj ntsig los ntawm cov tuam txhab tsim khoom hnyav calcium.Yog tias koj muaj cov kev xav tau tshwj xeeb ntawmhnyavcalcium sib tsoo zeb, thov hu rau HCM.
