ʻO ka calcium kaumaha, i ʻike ʻia hoʻi ʻo ka calcium carbonate lepo. He hui inorganic ia i hana ʻia me ka calcite, ke kinikini, ka limestone a me nā mea maka ʻē aʻe ma ke wili ʻana me kahikaumahawili wili kalipuna. No laila, he aha ka ʻokoʻa ma waena o ka calcium kaumaha i hana ʻia mai kēia mau mea hao? ʻO HCMilling (Guilin Hongcheng), ma ke ʻano he mea hana o kakaumahawili wili kalipuna i komo nui i ka ʻoihana calcium carbonate no nā makahiki he nui, e hana anaka wili kalapona Raymond, kalaka kalaponaʻoi loa ka maikaʻi wili wili apo, kalaka kalaponamaikaʻi loamaikaʻiwili wili kū pololei a me nā lako ʻē aʻe. Ke wehewehe nei kēia i ka ʻokoʻa ma waena o ka hana ʻana o ka calcium kaumaha, calcite, marble a me ka limestone.

1、ʻOkoʻa ka calcite, ke kinikini, ka pōhaku lepo

Calcite: he ʻāpana moakāka a me ka moakāka o ka ore. Ua māhele ʻia ka ʻili i nā mokulele moakāka, e ʻike mau ʻia ana ma hope o ka wāwahi ʻana. Ua pālahalaha nui ʻia ka wahi eli Calcite, a ua māhele ʻia hoʻi nā ore i ka calcite nui a me ka calcite liʻiliʻi. He ʻāpana moakāka ko ka calcite nui, maʻamau a kiʻekiʻe ka moakāka; He ʻano ʻole ka ʻāpana calcite, maikaʻi a ʻano ʻole. Pono e hoʻomaopopo ʻia he ʻekolu mau kala o ka ore calcite, ʻo ia hoʻi, ka pae keʻokeʻo waiū, ka pae melemele a me ka pae ʻulaʻula. Aia paha he ʻokoʻa i ke kala o kēlā me kēia wahi hana, a aia paha kekahi mau ʻokoʻa i nā waiwai optical o ka pauka calcium carbonate i hana ʻia. Eia kekahi, ʻoi aku ka nui o ka calcium o ka calcite ma mua o ke kinikini a me ka limestone, e hiki ana ma mua o 99%. ʻO ka hapa nui o nā haumia metala he Fe, Mn, Cu, a pēlā aku. ʻO ka density pili he 2.5 ~ 2.9 g / cm3, a ʻo ka paʻakikī Mohs he 2.7 ~ 3.0.

Māpala: ʻike ʻia hoʻi ʻo dolomite, ua haku ʻia ia me ka calcite, ka limestone, ka serpentine a me ka dolomite. I waena o lākou, ʻoi aku ka nui o ka calcium carbonate ma mua o 95%, ʻo ka paʻakikī Mohs ma waena o 2.5-5, a ʻo ka density he 2.6 a 2.8g/cm³.，Ua māhele ʻia ka ʻaila i loko o ka ʻaila kristal nui a me ka ʻaila kristal maikaʻi, a he cubic ke ʻano o ke kristal. ʻO ke kala o ke kinikini he uliuli (hina) keʻokeʻo, a ʻo ka nui o nā mea haumia e like me ka magnesium oxide (0.2% ~ 0.7%), ferric oxide (<0.08%), manganese (1 ~ 50mg/kg) e loli nui ana ma muli o ke kumu.

Pōhaku Limestone: ʻO ka Limestone kahi ʻano pōhaku me ka haku mele calcite hoʻokahi, ʻo ia ka hui pū ʻana o nā mea maikaʻi a aphanitic paha. Aia ia i ʻelua mau pae o ka calcite a me ka aragonite, a he palupalu a mānoanoa. Loaʻa i ka Limestone ma mua o 95% calcium carbonate, kahi liʻiliʻi o ka dolomite, siderite, quartz, feldspar, mica a me nā minelala lepo e hiki ke hōʻike i ke kala o ka pōhaku, ʻoi aku ka keʻokeʻo a me ka hina. ʻO nā haumia nui o ka limestone e komo pū ana me ka silicon dioxide, alumini oxide, hao oxide, magnesium, strontium, a pēlā aku. ʻO ka paʻakikī Mohs he 3.5 ~ 4, a ʻo ka density he 2.7 g / cm3.

2、Nā hoʻohana like ʻole o ka calcite, marble a me ka limestone

ʻO nā Palakiko: Hoʻohana nui ʻia ke kinikini a me ka calcite, akā he ʻokoʻa nā ʻano kala a me nā ʻano kristal o ka calcite a me ke kinikini. ʻOkoʻa ke kala, ka ikaika tensile a me ke kūpaʻa hopena o nā huahana i hoʻopiha ʻia i nā huahana plastik i kekahi ʻano. No ka ʻōnaehana kristal hexagonal ʻo Calcite, a ʻo ke kristal ma ke ʻano he nucleus lā, me ka lakio nui o nā diameters lōʻihi a pōkole; ʻO ke ʻano he cubic nā kristal kinikini, me ka lakio liʻiliʻi o nā diameters lōʻihi a pōkole. Hoʻopiha ʻia nā huahana e like me nā paipu PVC a me nā profiles me ka calcite a me ke kinikini me ka hoʻokaʻawale like ʻana o ka nui o nā ʻāpana ma lalo o ke ʻano like. ʻOi aku ka maʻalahi o ka palupalu o nā huahana i hana ʻia me ka pauka kinikini ma mua o nā mea i hana ʻia me ka pauka calcite, a ʻilihune ka paʻakikī.

Hana Pepa: ua koho ʻia ka calcite a me ke kinikini me ka paʻakikī haʻahaʻa a me ka palupalu o ke ʻano he mau mea maka calcium carbonate kaumaha, nona ka helu haʻahaʻa o nā lako, a he kūpono ia no ka pale ʻana a me ka hoʻolōʻihi ʻana i ke ola o ka pale kānana, ke poʻo ʻokiʻoki a me nā ʻāpana ʻē aʻe o ka mīkini pepa.

Pena Latex: ʻokoʻa loa ke ʻano o nā ʻano ʻai maka calcium carbonate like ʻole. Ma ke ʻano laulā, kiʻekiʻe ka maʻemaʻe o ka ʻai calcite, ʻoi aku ka nui o ka calcium carbonate ma mua o 96%, a haʻahaʻa a maʻalahi paha ka wehe ʻana i nā mea haumia e like me ka magnesium oxide a me ka ferric oxide, no laila ʻoi aku ka paʻa o ka pena latex.

ʻO HCMilling (Guilin Hongcheng), ma muli o ke kaulahao ʻoihana calcium carbonate, ua hāʻawi i ke kākoʻo lako maikaʻi no nā ʻoihana hana pauka calcium a puni ka honua. ʻO kā mākouka wili kalapona Raymond, kalaka kalapona ʻoi loa ka maikaʻiwili wili apo, kalaka kalaponamaikaʻi loamaikaʻiwili wili kū pololei a me nā lako hana hana calcium kaumaha ʻē aʻe e makemake nui ʻia e nā ʻoihana hana hana calcium kaumaha. Inā he mau pono kūpono kāukaumahawili wili kalipuna, e ʻoluʻolu e hoʻokaʻaʻike iā HCM.
