ʻO Kaolin, kahi mineral ʻaʻohe metala, he ʻano lepo a me ka pōhaku lepo i haku ʻia me nā mineral lepo hui kaolinite. Ma muli o kona ʻano keʻokeʻo a palupalu hoʻi, ua kapa ʻia hoʻi ʻo ia he lepo Baiyun. ʻO nā ʻāpana nui he alumini trioxide a me silicon dioxide

He keʻokeʻo kona ʻano kaolin maʻemaʻe, he palupalu, a he palupalu hoʻi, me nā waiwai kino a me nā kemika maikaʻi e like me ka plasticity a me ke kūʻē ʻana i ke ahi. ʻO kona ʻano minerala he kaolinite, halloysite, hydromica, illite, montmorillonite, a me nā minerala e like me ka quartz a me ka feldspar.

Nā ʻano hana:

1. Keʻokeʻo ʻĀlohilohi - ʻO ke keʻokeʻo kekahi o nā palena nui no ka hana ʻana o ke kaolin, a ʻo ke kaolin maʻemaʻe kiʻekiʻe he keʻokeʻo. Ua māhele ʻia ke keʻokeʻo o ke kaolin i ke keʻokeʻo maoli a me ke keʻokeʻo calcined. No nā mea maka seramika, ʻoi aku ka nui o ke keʻokeʻo ma hope o ka calcination, a ʻo ke kiʻekiʻe o ke keʻokeʻo calcined, ʻoi aku ka maikaʻi o ka maikaʻi.

2. Ka hoʻolaha ʻana o ka nui o nā ʻāpana - ʻO ka hoʻolaha ʻana o ka nui o nā ʻāpana e pili ana i ka hapa (i hōʻike ʻia ma ka pakeneka o ka nui) o nā ʻāpana i loko o ke kaolin kūlohelohe i loko o kahi laulā i hāʻawi ʻia o nā nui ʻāpana like ʻole (i hōʻike ʻia ma nā millimeters a i ʻole micrometer mesh). Loaʻa i kēlā me kēia keʻena ʻoihana nā koi kikoʻī no ka nui o nā ʻāpana a me ka maikaʻi o ke kaolin no nā kumu like ʻole. Pono ʻo ʻAmelika Hui Pū ʻIa i kaolin i hoʻohana ʻia ma ke ʻano he uhi e loaʻa ka ʻike ma lalo o 2 μ m (6250 mesh), e helu ana no 90-95%, a me nā mea hoʻopihapiha hana pepa me ka ʻike ma lalo o 2 μ m e helu ana no 78-80%. No nā kaʻina hana hoʻolei e pono ai ka hoʻolei wikiwiki, ka wikiwiki o ka grouting wikiwiki, a me ka wikiwiki o ka dehydration, pono e hoʻonui i ka nui o nā ʻāpana o nā mea hoʻohui.

3. Hoʻokuʻu ʻia: ʻO ka hoʻokuʻu ʻia a me ka hoʻopuehu ʻana e pili ana i nā waiwai o ke kaolin i paʻakikī ke hoʻopuehu ʻia i ka wai. ʻIke ʻia hoʻi he anti flocculation. ʻO ka liʻiliʻi o ka nui o ka ʻāpana, ʻoi aku ka maikaʻi o ka hoʻokuʻu ʻia. Pono nā waiwai hoʻokuʻu maikaʻi no ke Kaolin i hoʻohana ʻia i ka ʻoihana enamel. Hoʻoholo pinepine ʻia ka hana hoʻokuʻu o kahi hāpana i hoʻopuehu ʻia i ka wai e kona helu hoʻonoho ma luna o kekahi manawa.

4. Pale uila: Loaʻa i ke kaolin kiʻekiʻe nā waiwai pale uila maikaʻi, hiki ke hoʻohana ʻia e hana i nā keramika alapine kiʻekiʻe a me nā keramika uea ʻole. Hiki ke ana ʻia ka pae o ka hana pale uila ma o kona hiki ke kū i ka haki uila.

Hoʻokaʻawale ʻana:

Kaolin i holoi ʻia i ka wai metakaolin calcined

Hoʻohana:

He nui nā hoʻohana o Kaolin, hoʻohana nui ʻia i ka hana pepa, nā keramika, a me nā mea refractory, ukali ʻia e nā uhi, nā mea hoʻopihapiha rubber, nā glazes enamel, a me nā mea maka sima keʻokeʻo. I nā liʻiliʻi liʻiliʻi, hoʻohana ʻia ia ma nā ʻāpana ʻoihana e like me nā plastics, nā pena, nā pigments, nā huila wili, nā penikala, nā mea hoʻonani o kēlā me kēia lā, ke kopa, nā lole, ka petroleum, nā kemika, nā mea kūkulu hale, a pēlā aku.
