ʻO ka ʻāpana nui o ka talc he hydrotalcite hydrous magnesium silicate me ke ʻano molekala o mg3 [si4o10] (OH) 2. No ka ʻōnaehana monoclinic ʻo Talc. He pseudohexagonal a rhombic paha ke kristal, i kekahi manawa. He mau ʻāpana nui, lau, radial a fibrous lākou. He kala ʻole a moakaka a keʻokeʻo paha, akā he ʻōmaʻomaʻo māmā, melemele māmā, ʻeleʻele māmā a ʻulaʻula māmā paha ma muli o ka liʻiliʻi o nā haumia; ʻo ka ʻili cleavage he momi luster. Paʻakikī 1, umekaumaha kikoʻī 2.7-2.8.

Loaʻa i ka pauka Talc nā waiwai kino a me nā kemika maikaʻi loa e like me ka lubricity, ke kū'ē ʻana i ke ahi, ke kū'ē ʻana i ka waikawa, ka insulation, ke kiko heheʻe kiʻekiʻe, ka hana ʻole o nā kemika, ka mana uhi maikaʻi, ka palupalu, ka luster maikaʻi, ka adsorption ikaika, a me nā mea ʻē aʻe. no ka mea he papa ke ʻano o ka kristal o ka talc, he ʻano maʻalahi ka māhele ʻana i nā unahi a me ka lubricity kūikawā. Inā kiʻekiʻe loa ka nui o Fe2O3, e emi ana kona insulation.

Ka hoʻohana ʻana o ka talc:

(1) Papa hoʻonani (Hz): hoʻohana ʻia no nā ʻano pauka moisturizing āpau, pauka nani, pauka talcum, a pēlā aku.

(2) Papa lāʻau lapaʻau (YS): papa lāʻau lapaʻau, uhi kō, pauka wela ʻōʻō, kuhikuhi lāʻau lapaʻau Kina, mea hoʻohui meaʻai, mea hoʻokaʻawale, a pēlā aku.

(3) Papa uhi (TL): hoʻohana ʻia no ka pigment kino keʻokeʻo a me nā ʻano uhi wai āpau, ʻaila, resin industrial coatings, primer, pena pale, a pēlā aku.

(4) Papa pepa (zz): hoʻohana ʻia e like me ka mea hoʻopiha no nā ʻano pepa a me ka pepa pepa āpau, mea hoʻomalu ʻakipa lāʻau.

(5) Papa palakiko (SL): hoʻohana ʻia e like me ka mea hoʻopiha no ka polypropylene, nylon, polyvinyl chloride, polyethylene, polystyrene, polyester a me nā palakiko ʻē aʻe.

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