Calcium hnyav, tseem hu ua cov duab calcium calcium carbonate. Nws yog kev sib xyaw ua ke ua los ntawm calcacacic ua los ntawm calcite, marble, limestone thiab lwm yam ore cov khoom siv los ntawm kev sib tsoo nrog ahnyavcalcium sib tsoo zebCov. Yog li, yog li cas qhov sib txawv ntawm cov calcium hnyav uas tsim los ntawm cov khoom ore no? HCMILLING (GUILIN Hongcheng), raws li cov chaw tsim khoom ntawm lubhnyavcalcium sib tsoo zeb uas tau muaj kev koom tes nrog cov calcium carbon monoxate kev lag luam ntau xyoo, tsim tawmcalcium carbonate raymond zeb, calcium carbonateultra-nplua Ntiv nplhaib cov menyuam zeb, calcium carbonatezoo kawg nkausnpluasNtsug Cov Menyuam Zeb thiab lwm yam khoom siv. Cov hauv qab no qhia txog qhov sib txawv ntawm kev tsim cov calcium hnyav, calcite, marble thiab limestone.

1,Sib piv cov calcite, marble, limestone

Calcite: Tus ore muaj cleavage ntshiab thiab pob tshab. Qhov saum npoo tau muab faib ua cov dav hlau ntshiab, uas tseem pom tom qab kev sib tsoo. Calcite thaj chaw tsuas faib tau dav, thiab ores kuj tau muab faib ua cov calcite thiab calcite me me. Cov Calcite muaj cov cleavage tshem tawm, tsis tu ncua thiab siab pob tshab; Calcite cleavage yog disordered, nplua thiab tsis xwm yeem. Nws yuav tsum raug sau tseg tias muaj peb xim ntawm nplooj ore calcite, uas yog, milky dawb theem, theem daj daj thiab xim liab. 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 tshiab ntawm cov tshuaj calcium carbonate hmoov. Ib qho ntxiv, cov calcium cov ntsiab lus ntawm calcium yog siab dua li ntawm marble thiab limestone, ncav ntau tshaj 99%. Feem ntau ntawm cov hlau hluav taws xob yog FE, MN, Cu, thiab lwm yam. Tus txheeb ze lub zog yog 2.5 ~ 2.9 G / CM3, thiab Mohs Hardness yog 2.7 ~ 3.0.

Marble: tseem hu ua dolomite, nws yog tsim ntawm calcomite, nws yog tsim ntawm calcite, limestone, Serpentine thiab dolomentine. Ntawm lawv, cov muaj pes muaj pes tsawg leeg ntawm calcium carbonate nyiaj rau ntau dua 95%, lub mohs hardness yog nruab nrab ntawm 2.5-5, thiab lub ntom ntom yog 2.6 rau 2.8g / cm / cm ³,Lub ore tau muab faib ua coarse crystal ore thiab zoo crystal ore, thiab cov siv lead yog feem ntau cubic. Lub suab paj nruag marble feem ntau yog xiav (grey) dawb, thiab cov ntsiab lus ntawm cov oluries xws li magnesium (0.2%), mangg / kg) txawv nyob ntawm lub hauv paus chiv keeb Cov.

Limestone: Limestone yog ib hom pob zeb uas muaj ib qho hluav taws kub uas muaj cov ntxhia pob zeb ntxiv, uas yog kev sib txuam ntawm cov ntaub ntawv APHANITIC. Nws muaj nyob rau hauv ob ntu ntawm calcite thiab aragonite, thiab yog nkig thiab ntom. Limestone muaj ntau dua 95% carbon carbonate, ib qho me me ntawm dolomite, cov me me thiab cov pob zeb av nplaum uas tuaj yeem cuam tshuam cov xim ntawm pob zeb, feem ntau yog dawb thiab grey. Cov impurities tseem ceeb ntawm lub lim tiam suav nrog silicon dioxide, Txhuas Oxide, Hlau Oxide, Mags Hardness yog 3.5, thiab lub qhov ntom yog 2.7 g / cm3.

2,Sib txawv kev siv calcite, marble thiab limestone

Cov Plastics: Marble thiab Calcite yog siv dav, tab sis calcite thiab marble muaj cov xim sib txawv thiab cov siv lead ua. Cov xim, lub tensile quab yuam thiab cuam tshuam cov khoom lag luam tau sau hauv cov khoom yas yuav txawv rau qee yam. Calcite yog rau hexagonal crystal system, thiab cov siv lead ua feem ntau yog nyob rau hauv cov duab ntawm ib lub hnub nucleus, nrog ib qho kev sib piv loj ntawm ntev diameters; Marble muaju feem ntau yog lo lus teb rau hauv cov duab, nrog ib qho me me ntawm ntev diameters luv. Cov khoom lag luam xws li cov kav dej pheeb thiab cov profiles thiab txhais tau tias muaj cov calcite thiab marble nrog tib lub particle loj faib hauv tib cov mis. Cov khoom ua los ntawm marble hmoov yog qhov yooj yim dua li cov hmoov ntau dua li cov ua los ntawm cov hmoov ntawm calcite, thiab cov tawv tsis zoo.

Papermaking: Calcite thiab marble nrog qis hardness thiab softer zoo yog xaiv los ua kev tiv thaiv cov khoom nyoos, thiab nthuav tawm lub neej ntawm cov tshuab lim thiab lwm lub taub hau ntawm cov ntawv tshuab.

Cov xim loojxia looj: Qhov sib xyaw ntawm cov calcium cov roj carbonate sib txawv raw ores sib txawv heev. Feem ntau, cov ore calcite yog qhov siab, cov ntsiab lus calcium carbonate thiab yooj yim kom tshem tawm, yog li cov xim yas ruaj khov.

HCMILLING (GUILIN Hongcheng), raws li cov calcium carbonate kev lag luam kev lag luam, tau muab cov cuab yeej siv zoo rau cov khoom lag luam calcium hmoov thoob ntiaj teb. Peb licalcium carbonate raymond zeb, calcium carbonate ultra-npluaNtiv nplhaib cov menyuam zeb, calcium carbonatezoo kawg nkausnpluasNtsug Cov Menyuam Zeb Thiab lwm cov cuab yeej siv hluav taws xob ntau cov khoom siv tseem muaj kev nyiam los ntawm cov lag luam calcium hnyav ntau lawm. Yog tias koj muaj kev xav tau ntawmhnyavcalcium sib tsoo zeb, thov hu rau HCM.
