ʻO ka mea nui o ka talc he magnesium silicate i loko o ka wai, me ka molecular formula Mg3 [Si4O10] (OH) 2. No ka ʻōnaehana monoclinic ka talc.Aia ke aniani ma ke ʻano o pseudo hexagonal a i ʻole rhombic flakes, ʻike ʻia i kekahi manawa.Hoʻokumu mau ʻia i ʻōpuʻupuʻu paʻa, e like me ka lau, radial, a me nā ʻāpana fibrous.ʻAʻohe kala ʻulaʻula a keʻokeʻo paha, akā he ʻōmaʻomaʻo ʻōmaʻomaʻo, melemele māmā, ʻulaʻula ʻulaʻula paha ma muli o ka liʻiliʻi o nā mea haumia;Hōʻike ka ʻili o ka puʻupuʻu i kahi ʻulaʻula momi.ʻO ka paʻakikī 1, ka umekaumaha kikoʻī 2.7-2.8.

Loaʻa i ka Talc nā waiwai kino a me nā kemika maikaʻi e like me ka lubricity, anti adhesion, kōkua kahe, pale ahi, pale ʻana i ka waikawa, insulation, kiʻekiʻe heheʻe kiʻekiʻe, nā mea kemika hana ʻole, mana uhi maikaʻi, palupalu, luster maikaʻi, a me ka adsorption ikaika.Ma muli o kona ʻano ʻano aniani i hoʻopaʻa ʻia, ua maʻalahi ka maʻalahi o ka talc i nā unahi a me ka lubricity kūikawā.Inā kiʻekiʻe ka maʻiʻo o Fe2O3, e hoʻemi ia i kona insulation.

He palupalu ʻo Talc, me kahi helu paʻakikī Mohs o 1-1.5 a me kahi ʻano sliding.{001} Ua piha loa ka mahele, a ua ma'alahi ka nahae i mau apana lahilahi.He liʻiliʻi ke kihi hoʻomaha kūlohelohe (35 ° ~ 40 °), a paʻa loa ia.ʻO ka pōhaku a puni he silicified a paheʻe ka magnesite, magnesite, lean ore, a me ka marble dolomite.Koe wale no kekahi mau pohaku pa'a pa'a, 'ano pa'a 'ole, me na ami a me na haki.He hopena koʻikoʻi ka ʻano kino a me ka mechanical o ka oka a me ka pōhaku a puni i ke kaʻina hana eli.

Papa kemika
Hoʻohana: Hoʻohana ʻia ma ke ʻano he mea hoʻopihapiha hoʻoikaika a hoʻololi i nā ʻoihana kemika e like me ka rubber, plastics, paint, etc. ka hoʻonui ʻana, ke keʻokeʻo kiʻekiʻe, a me ka like ʻana o ka nui o nā ʻāpana ikaika a me ka dispersion.

Papa seramika
Hoʻohana: Hoʻohana ʻia no ka hana ʻana i nā ceramics kiʻekiʻe, nā seramika uila, nā seramika ʻoihana like ʻole, nā seramika hoʻolālā, nā seramika i kēlā me kēia lā, a me nā glazes seramika.Nā hiʻohiʻona: ʻAʻole wehe ʻia ka wela kiʻekiʻe, hoʻonui ʻia ke keʻokeʻo ma hope o ka hana ʻana, ʻano like ʻole, luster maikaʻi, a maʻemaʻe ka ʻili.

Papa hoʻonani
Ke kumu: He mea hoʻopihapiha hoʻopihapiha kiʻekiʻe i ka ʻoihana cosmetic.Nā hiʻohiʻona: Loaʻa ka nui o nā mea silika.Loaʻa iā ia ka hana o ka pale ʻana i nā kukuna infrared, no laila e hoʻonui ai i ka pale o ka lā a me ka hana kūʻē infrared o nā mea hoʻonaninani.

Lapaʻau a me ka papaʻai
Hoʻohana: Hoʻohana ʻia ma ke ʻano he mea hoʻohui i ka lāʻau lapaʻau a me nā ʻoihana meaʻai.Nā hiʻohiʻona: ʻAʻohe mea ʻawaʻawa, ʻala ʻole, me ke keʻokeʻo kiʻekiʻe, ka hoʻohālikelike maikaʻi ʻana, ka glossiness ikaika, ka ʻono palupalu, a me ka maʻalahi ikaika.ʻAʻole hoʻohaʻahaʻa ka pH waiwai o 7-9 i nā ʻano o ka huahana kumu.

Papa pepa
Ke kumu: Hoʻohana ʻia no nā huahana ʻoihana pepa kiʻekiʻe a haʻahaʻa.Nā hiʻohiʻona: Loaʻa i ka pauka pepa nā hiʻohiʻona o ke keʻokeʻo kiʻekiʻe, ka nui o ka ʻāpana paʻa, a me ke kapa haʻahaʻa.ʻO ka pepa i hana ʻia me kēia pauka hiki ke hoʻokō i ka maʻalahi, ka momona, mālama i nā mea maka, a hoʻomaikaʻi i ke ola lawelawe o ka resin mesh.

ʻO ka pauka Brucite
Hoʻohana: Hoʻohana ʻia no ka hana ʻana i ka porcelain uila, porcelain uila uila, nā seramika ʻoihana like ʻole, nā seramika hoʻolālā, nā seramika i kēlā me kēia lā, a me ka glaze ceramic.Nā hiʻohiʻona: Kiʻekiʻe wela non discoloration, hoʻonui keʻokeʻo ma hope o ka hoʻopaʻa ʻana, ʻano like ʻole, ʻālohilohi maikaʻi, a me ka ʻili malū.
