Heavy calcium, yomwe imadziwikanso kuti calcium carbonate.Ndi mankhwala opangidwa ndi calcite, marble, miyala yamchere ndi zina zopangira ore pogaya ndizolemetsamphero ya calcium.Ndiye pali kusiyana kotani pakati pa kashiamu wolemera wopangidwa kuchokera ku zinthu zachitsulo izi?HCMilling(Guilin Hongcheng), monga Mlengi wazolemetsamphero ya calcium zomwe zakhala zikukhudzidwa kwambiri ndi makampani a calcium carbonate kwa zaka zambiri, zimapangakashiamu carbonate Raymond mphero, calcium carbonatezabwino kwambiri mphero yodzigudubuza, calcium carbonatewapamwambachabwinovertical roller mphero ndi zida zina.Zotsatirazi zikufotokozera kusiyana pakati pa kupanga kashiamu wolemera, calcite, marble ndi miyala yamchere.

1,Kusiyanitsa calcite, marble, miyala yamchere

Calcite: miyalayi ili ndi kung'ambika bwino komanso kuwonekera.Kumwamba kumagawidwa kukhala ndege zomveka bwino, zomwe zikuwonekerabe pambuyo pophwanya.Dera la migodi ya calcite limagawidwa kwambiri, ndipo ore amagawidwanso kukhala calcite yayikulu ndi calcite yaying'ono.Calcite yaikulu imakhala ndi cleavage yomveka, yokhazikika komanso yowonekera kwambiri;calcite cleavage ndi yosokonezeka, yabwino komanso yosasinthika.Kuyenera kudziŵika kuti pali mitundu itatu ya calcite ore, ndicho, yamkaka woyera gawo, chikasu gawo ndi pabuka gawo.Pakhoza kukhala kusiyana kwa mtundu wa malo aliwonse opangira, ndipo pangakhale kusiyana kwa kuwala kwa ufa wopangidwa ndi calcium carbonate.Kuonjezera apo, calcium yomwe ili mu calcite ndi yochuluka kuposa ya marble ndi miyala yamchere, kufika kupitirira 99%.Zambiri zazitsulo zachitsulo ndi Fe, Mn, Cu, etc. Kuchulukana kwachibale ndi 2.5 ~ 2.9 g / cm3, ndipo kuuma kwa Mohs ndi 2.7 ~ 3.0.

Marble: amadziwikanso kuti dolomite, amapangidwa ndi calcite, miyala yamchere, serpentine ndi dolomite.Pakati pawo, mapangidwe a calcium carbonate amaposa 95%, kuuma kwa Mohs kuli pakati pa 2.5-5, ndi kachulukidwe ndi 2.6 mpaka 2.8g/cm ³,Miyalayo imagawidwa kukhala miyala yamtengo wapatali ya kristalo ndi miyala yabwino ya kristalo, ndipo kristaloyo nthawi zambiri imakhala ya cubic.Mtundu wa nsangalabwi makamaka umakhala wa buluu (imvi) woyera, ndipo zonyansa monga magnesium oxide (0.2% ~ 0.7%), ferric oxide (<0.08%), manganese (1~50mg/kg) zimasiyana kwambiri malinga ndi chiyambi. .

Limestone: Mwala wa laimu ndi mtundu wa mwala womwe uli ndi mchere umodzi wa calcite, womwe umaphatikizana ndi zinthu zabwino kapena za aphanitic.Imapezeka m'magawo awiri a calcite ndi aragonite, ndipo imakhala yolimba komanso yowundana.Limestone ili ndi zoposa 95% calcium carbonate, pang'ono ya dolomite, siderite, quartz, feldspar, mica ndi mchere wadongo womwe ungasonyeze mtundu wa miyala, makamaka yoyera ndi imvi.Zonyansa zazikulu za miyala ya laimu zimaphatikizapo silicon dioxide, aluminium oxide, iron oxide, magnesium, strontium, etc. Kulimba kwa Mohs ndi 3.5 ~ 4, ndipo kachulukidwe ndi 2.7 g / cm3.

2,Ntchito zosiyanasiyana za calcite, marble ndi miyala yamchere

Pulasitiki: Marble ndi calcite amagwiritsidwa ntchito kwambiri, koma calcite ndi marble ali ndi magawo amtundu wosiyana komanso mawonekedwe a kristalo.Mtundu, mphamvu yolimba komanso kukana kwazinthu zodzazidwa ndi zinthu zapulasitiki zidzakhala zosiyana pamlingo wina.Calcite ndi ya hexagonal crystal system, ndipo kristaloyo nthawi zambiri imakhala ngati phata la deti, yokhala ndi chiŵerengero chachikulu cha ma diameter aatali mpaka aafupi;Makhiristo a nsangalabwi nthawi zambiri amakhala ndi mawonekedwe a cubic, okhala ndi chiŵerengero chaching'ono cha mainchesi aatali mpaka aafupi.Zogulitsa monga mapaipi a PVC ndi mbiri zimadzazidwa ndi calcite ndi marble ndi kugawa kwa tinthu komweko pansi pa chilinganizo chomwecho.Zopangidwa ndi ufa wa nsangalabwi ndizosavuta kukhala zolimba kuposa zopangidwa ndi ufa wa calcite, ndipo kulimba kwake kumakhala koyipa.

Papermaking: calcite ndi nsangalabwi ndi otsika kuuma ndi khalidwe zofewa amasankhidwa monga heavy calcium carbonate yaiwisi, amene ali otsika kavalidwe zipangizo, ndi yabwino kuteteza ndi kukulitsa moyo wa fyuluta chophimba, wodula mutu ndi mbali zina za pepala makina.

Utoto wa latex: kaphatikizidwe kamitundu yosiyanasiyana ya calcium carbonate yaiwisi yaiwisi imasiyanasiyana kwambiri.Nthawi zambiri, chiyero cha calcite ore chimakhala chokwera, calcium carbonate imakhala yoposa 96%, ndipo zonyansa monga magnesium oxide ndi ferric oxide ndizochepa kapena zosavuta kuchotsa, kotero utoto wa latex umakhala wokhazikika.

HCMilling(Guilin Hongcheng), zochokera unyolo kashiamu carbonate makampani, wapereka zida zabwino thandizo mabizinesi kashiamu ufa processing padziko lonse.Zathukashiamu carbonate Raymond mphero, calcium carbonate zabwino kwambirimphero yodzigudubuza, calcium carbonatewapamwambachabwinovertical roller mphero ndi zida zina zopangira kashiamu zolemera zimakondedwanso ndi mabizinesi olemera a calcium.Ngati muli ndi zofunikira zazolemetsamphero ya calcium, lemberani HCM.
