Hoʻomākaukau ʻia ka pauka Talc e talcwili wili mīkini. ʻO Talc kekahi o nā minelala. Ua kanu ʻia ia ma lalo o ka honua me ka serpentinite e loaʻa ana ka asbestos, no laila loaʻa pinepine iā ia ka asbestos i kona ʻano kūlohelohe. Ua hoʻopaʻapaʻa nui ʻia ka hiki ke loaʻa ka asbestos i loko o ka pauka talc lapaʻau i nā makahiki i hala iho nei. ʻO ka pilikia mua i kū i ka pauka talc i ka mālama ʻana i ka lāʻau lapaʻau ʻo ia ka pilikia palekana. I kēia manawa, loaʻa i ka pauka talc lapaʻau kahi kaʻina hana kūikawā e hōʻoia i ka palekana olakino. Ma ke ʻano he mea hana ʻoihana opauka talc wili Raymond, E kūkākūkā ʻo HCMilling (Guilin Hongcheng) me ʻoe i ka hana ʻana o ka pauka talc lapaʻau a me ka hoʻopili ʻana opauka talc wili Raymond.

Pehea e hoʻoholo ai inā he lāʻau lapaʻau ka pauka talc? He nui nā hopena o ka pauka talc lapaʻau, e like me ka hoʻomaʻemaʻe ʻana i ka wela, ka hoʻoheheʻe ʻana i ka wai, ka pono o nā puka, ka hoʻōla ʻana i ka wela a me ka make wai, ka mimi maikaʻi ʻole, ka maʻi diarrhea, ka dysentery, ka gonorrhea, ka jaundice, ka edema, ke kahe ʻana o ke koko, ka beriberiberi, a me ka ʻili pulu. ʻO ka mea hoʻoheheʻe ʻia i loko o ka waikawa he hōʻailona koʻikoʻi ia o ka pauka talc lapaʻau. Hōʻike nā ʻikepili pili i ka mea hoʻoheheʻe ʻia i loko o ka waikawa o nā pauka talc lapaʻau he nui i kūʻai ʻia ma ka mākeke ma mua o 2.0% o ka mea i kuhikuhi ʻia e ka Pharmacopoeia Kina. He kuhikuhi koʻikoʻi ia e hōʻoia ʻaʻole i loaʻa ka asbestos i loko o ka pauka talc lapaʻau. Ma keʻano laulā, ʻo ka hoʻomākaukau ʻana i ka pauka talc lapaʻau me ka talc ma ke ʻano he mea maka e hana nui ʻia ma o ka hui pū ʻana o ke kaʻina hana.

Ke kaʻina hana o ka pauka talc lapaʻau: ʻo ka mea mua, ua hana ʻia ka ore talc maka i loko o ka pauka talc coarse e wili wili talc, me ka maikaʻi o kahi 325 mesh; A laila, ka hoʻokaʻawale magnetic a me ka wehe ʻana i ka haumia. Hoʻohui ʻia ka pauka talc maka me ka wai e hoʻomākaukau ai i ka slurry, a hoʻohui ʻia ka nui kūpono o ka sodium silicate. Ma hope o ka hui ʻana, hoʻouna ʻia ka pauka talc i loko o ka mea hoʻokaʻawale magnetic nāwaliwali ma kahi wikiwiki hānai, a wehe ʻia nā haumia ma lalo o kahi ikaika kahua magnetic; A laila hoʻomaʻemaʻe waikawa. E kāwili i ka pauka talc i hoʻokaʻawale ʻia me ka nui kūpono o ka wai, e kāwili i ka slurry a me ka hydrochloric acid me 20% nui o ka pauka talc maka o 10-30%, e hoʻoulu like a hiki i ka ʻole o nā pehu e hana ʻia ma ka ʻili wai, kānana, holoi me ka wai a hiki i ka neutral o ka wai holoi, a laila hoʻomaʻemaʻe flotation; E hoʻohui i ka nui kūpono o ka wai i ka pauka talc i holoi ʻia me ka waikawa e hoʻomākaukau ai i ka pulp, e hoʻohui i ka pulp a me ka hui flotation me ka 0.03-0.2% nui o ka pauka talc maka i loko o ka pahu hui pulp no ka hui ʻana, a laila e hoʻohui i ka pulp i loko o ka pahu flotation no ka flotation; ʻO ka mea hope loa, ua holoi ʻia nā huahana i hoʻomaʻemaʻe ʻia i koho ʻia, kānana ʻia a hoʻomaloʻo ʻia, a ʻo ka mea hope loa ua loaʻa ka pauka talc kūlana lāʻau lapaʻau.

He mea hoʻolako loea ʻo HCMilling (Guilin Hongcheng) wili wili talcʻO kā mākou moʻo HC a meTalc moʻo HCQHale wili ʻo Raymond ua hoʻohana nui ʻia ma ka mākeke hana talc. I mea e hoʻokō ai i nā pono o ka hana talc lapaʻau, hiki ke hoʻopilikino ʻia nā paipu kila kila e hōʻoia i ka keʻokeʻo o ka huahana i hoʻopau ʻia. Inā he koi kāu no ka hana ʻana o ka pauka talc lapaʻau a pono e kūʻaitalcwili wilimīkini, e ʻoluʻolu e leka uila mai iā mākou e aʻo i nā kikoʻī o ka lako otalc Raymondwilimīkini.
