Cov calcium hnyav, tseem hu ua calcium carbonate av. 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 ahnyavcalcium sib tsoo zebYog li, qhov txawv ntawm cov calcium hnyav uas tsim los ntawm cov khoom siv ore no yog dab tsi? HCMilling (Guilin Hongcheng), ua tus tsim khoom ntawmhnyavcalcium sib tsoo zeb uas tau koom nrog tob hauv kev lag luam calcium carbonate tau ntau xyoo, tsim tawmRaymond zeb calcium carbonate, calcium carbonatezoo heev lub nplhaib sib tsoo zeb, calcium carbonatezoo kawg linpluantsug roller zeb 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,Kev sib piv ntawm calcite, marble, limestone

Calcite: cov ore muaj qhov sib cais meej thiab pob tshab. Qhov saum npoo yog muab faib ua cov dav hlau meej, uas tseem pom tom qab tsoo. Thaj chaw khawb av Calcite tau faib dav dav, thiab cov ores kuj tau muab faib ua calcite loj thiab calcite me. Calcite loj muaj qhov sib cais meej, tsis tu ncua thiab pob tshab siab; Qhov sib cais calcite yog disordered, zoo thiab tsis xwm yeem. Nws yuav tsum tau sau tseg tias muaj peb xim ntawm calcite ore, uas yog, theem dawb milky, theem daj thiab theem liab. Tej zaum yuav muaj qhov sib txawv ntawm cov xim ntawm txhua thaj chaw tsim khoom, thiab tej zaum yuav muaj qee qhov sib txawv ntawm cov khoom siv kho qhov muag ntawm cov hmoov calcium carbonate ua tiav. Tsis tas li ntawd, cov ntsiab lus calcium ntawm calcite siab dua li ntawm marble thiab limestone, ncav cuag ntau dua 99%. Feem ntau ntawm cov hlau tsis huv yog Fe, Mn, Cu, thiab lwm yam. Qhov sib piv ntawm qhov ceev 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, cov khoom sib xyaw ntawm calcium carbonate suav rau ntau dua 95%, Mohs hardness yog nruab nrab ntawm 2.5-5, thiab qhov ceev yog 2.6 txog 2.8g / cm³,Cov ore no muab faib ua cov ore siv lead ua ntxhib thiab cov ore siv lead ua zoo, thiab feem ntau yog cubic. Lub suab marble feem ntau yog xiav (grey) dawb, thiab cov ntsiab lus ntawm cov khoom tsis huv xws li magnesium oxide (0.2% ~ 0.7%), ferric oxide (<0.08%), manganese (1 ~ 50mg / kg) sib txawv ntau nyob ntawm keeb kwm.

Pob zeb limestone: Pob zeb limestone yog ib hom pob zeb uas muaj cov khoom siv calcite, uas yog kev sib xyaw ua ke ntawm cov khoom zoo lossis aphanitic. Nws muaj nyob rau hauv ob theem ntawm calcite thiab aragonite, thiab yog brittle thiab ntom. Pob zeb limestone muaj ntau dua 95% calcium carbonate, me me ntawm dolomite, siderite, quartz, feldspar, mica thiab av nplaum minerals uas tuaj yeem cuam tshuam cov xim ntawm pob zeb, feem ntau yog dawb thiab grey. Cov khoom tsis huv tseem ceeb ntawm limestone suav nrog 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

Yas: Marble thiab calcite yog siv dav, tab sis calcite thiab marble muaj cov xim sib txawv thiab cov qauv siv lead ua. Cov xim, lub zog tensile thiab kev cuam tshuam ntawm cov khoom uas tau ntim rau hauv cov khoom yas yuav txawv rau qee qhov. Calcite koom nrog lub hexagonal crystal system, thiab cov siv lead ua feem ntau yog nyob rau hauv cov duab ntawm lub hnub tim nucleus, nrog rau qhov sib piv loj ntawm cov kab ntev mus rau luv luv; Marble siv lead ua feem ntau yog cubic hauv cov duab, nrog rau qhov sib piv me me ntawm cov kab ntev mus rau luv luv. Cov khoom xws li PVC kav thiab profiles tau ntim nrog calcite thiab marble nrog tib qhov loj me faib nyob rau hauv tib lub mis. Cov khoom ua los ntawm marble hmoov yooj yim dua li cov uas ua los ntawm calcite hmoov, thiab qhov toughness tsis zoo.

Kev ua ntawv: calcite thiab marble nrog qhov nyuaj tsawg thiab zoo softer raug xaiv ua cov khoom siv calcium carbonate hnyav, uas muaj qhov hnav qis ntawm cov khoom siv, thiab yog qhov zoo rau kev tiv thaiv thiab txuas ntxiv lub neej ntawm lim lim, lub taub hau txiav thiab lwm qhov ntawm lub tshuab ntawv.

Xim pleev xim latex: cov khoom sib xyaw ntawm cov calcium carbonate nyoos sib txawv heev. Feem ntau, qhov huv ntawm calcite ore yog siab, cov calcium carbonate cov ntsiab lus yog ntau dua 96%, thiab cov ntsiab lus ntawm cov khoom tsis huv xws li magnesium oxide thiab ferric oxide yog qis lossis yooj yim tshem tawm, yog li cov xim pleev xim latex ruaj khov dua.

HCMilling (Guilin Hongcheng), raws li cov saw hlau kev lag luam calcium carbonate, tau muab kev txhawb nqa cov khoom siv zoo rau cov tuam txhab ua hmoov calcium thoob ntiaj teb. PebRaymond zeb calcium carbonate, calcium carbonate zoo heevlub nplhaib sib tsoo zeb, calcium carbonatezoo kawg linpluantsug roller zeb thiab lwm yam khoom siv tsim cov calcium hnyav kuj tau txais kev nyiam los ntawm cov tuam txhab tsim cov calcium hnyav.
