He huahana ʻoihana ka pauka Talc, no ka hui talc o nā minelala magnesium silicate. ʻO kāna ʻāpana nui he magnesium silicate hydrated, kahi i kuʻi ʻia, mālama ʻia me ka waikawa hydrochloric, holoi ʻia me ka wai, a maloʻo. ʻO ka ʻāpana nui o ka talc he magnesium silicate i loaʻa ka wai, me kahi ʻano molekala o Mg3 [Si4O10] (OH) 2; No Talc ka ʻōnaehana kristal monoclinic. Aia nā kristal i ke ʻano o nā ʻāpana pseudo hexagonal a rhombic paha, i ʻike pinepine ʻia. Hoʻokumu pinepine ʻia i loko o nā puʻupuʻu mānoanoa, e like me ka lau, radial, a me nā fibrous aggregates. ʻAʻohe kala a keʻokeʻo paha, akā ʻike ʻia he ʻōmaʻomaʻo māmā, melemele māmā, ʻeleʻele māmā, a ʻulaʻula māmā paha ma muli o ke alo o nā mea haumia liʻiliʻi; Loaʻa i ka ʻili cleavage kahi luster momi. Paʻakikī 1, umekaumaha kikoʻī 2.7-2.8

Kaʻina hana:

Hiki ke kuʻi pololei ʻia ka talc i unuhi ʻia (ka mea maka o ka pauka talc) e ka wili Raymond a i ʻole nā ​​wili kaomi kiʻekiʻe ʻē aʻe ma hope o ke koho ʻana i ka talc maikaʻi loa, a hoʻopili ʻia i loko o nā ʻeke ulana (50kg, a i ʻole 25kg mau ʻeke ulana kikoʻī) ma mua o ke kūʻai ʻia ʻana ma ke ʻano he huahana i hoʻopau ʻia. Ma ke ʻano o nā ʻano hana mining, ma muli o ka ore paʻa ʻole loa a me ka pōhaku e hoʻopuni ana, ʻo ke kino ore he hiʻohiʻona nui a me nā kino ore mānoanoa a ʻoi aku ka mānoanoa. ʻOkoʻa loa ke ʻano a me ka mānoanoa o ke kino ore, a he nui nā pōhaku i hoʻopili ʻia i loko o ke kino ore. I ka wā ma mua, ua hoʻohana ʻia ke ʻano koho papa pālahalaha a me ka hoʻopiha ʻana i ka mining (hoʻohana mau kekahi mau mines i kēia ʻano).

ʻAno:

Loaʻa iā ia nā waiwai kino a me nā kemika maikaʻi loa e like me ka lubrication, ke kū'ē ʻana i ke ahi, ke kū'ē ʻana i ka waikawa, ka insulation, ke kiko heheʻe kiʻekiʻe, nā waiwai kemika hana ʻole, ka mana uhi maikaʻi, ka palupalu, ka ʻōlinolino maikaʻi, a me ka adsorption ikaika. Ma muli o ke ʻano kristal papa o ka talc, he ʻano maʻalahi ia e māhelehele i nā unahi a me ka lubricity kūikawā

Noi：

Papa hoʻonani (HZ): hoʻohana ʻia no nā pauka moisturizing like ʻole, nā pauka nani, ka pauka kino, a pēlā aku.

Papa uhi (TL): Hoʻohana ʻia no ka pigment keʻokeʻo a me nā ʻano uhi ʻoihana like ʻole e pili ana i ka wai, ka ʻaila, ka resin, nā primers, nā pena pale, a pēlā aku.

Papa pepa (ZZ): Hoʻohana ʻia ma ke ʻano he mea hoʻopiha no nā ʻano pepa like ʻole a me ka pepa pepa, ma ke ʻano he mea hoʻomalu ʻakila lāʻau.

Papa palakiko (SL): Hoʻohana ʻia ma ke ʻano he mea hoʻopiha no nā palakiko e like me ka polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene, a me ka polyester.

Papa laholio (AJ): hoʻohana ʻia no nā mea hoʻopiha laholio a me nā mea hoʻopili anti i nā huahana laholio.
