Kaolin ivhu risiri resimbi, iro riri rudzi rwedombo revhu nevhu rine minerals dzevhu dzeboka reKaolinite. Nekuda kwechitarisiko chayo chena uye chakapfava, inozivikanwawo sevhu reBaiyun. Yakatumidzwa zita kubva kuGaoling Village muJingdezhen, Jiangxi Province.

Kaolin yayo yakachena yakachena, ine hunyoro uye yakafanana neMollisol, ine plasticity yakanaka, inodzivirira moto uye zvimwe zvinhu zvemuviri uye zvemakemikari. Muumbirwo wayo wezvicherwa unonyanya kuumbwa neKaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar nezvimwe zvicherwa. Kaolin inoshandiswa zvakanyanya mukugadzira mapepa, zveceramics, uye zvinhu zvinoramba kusimba, ichiteverwa nependi, rabha fillers, enamel glazes, uye chena simende zvinhu zvakabikwa. Chidimbu chinoshandiswa mupurasitiki, pendi, pigments, grinding wheels, mapenzura, zvizoro zvezuva nezuva, sipo, mishonga yezvipembenene, mishonga, machira, peturu, makemikari, zvinhu zvekuvaka, dziviriro yenyika, nezvimwe zvikamu zveindasitiri.
Kaolin yave chinhu chakakosha chezvicherwa mumaindasitiri akawanda akadai sekugadzira mapepa, zvedongo, rabha, makemikari, machira, mishonga, uye dziviriro yenyika.

Indasitiri yeceramic ndiyo indasitiri yekutanga uye inonyanya kushandiswa pakushandisa kaolin. Chiyero chikuru i20% kusvika 30% yefomula. Basa rekaolin muceramics nderekuisa Al2O3, iyo inobatsira pakuumbwa kwemullite, ichivandudza kugadzikana kwayo kwemakemikari uye simba rekupisa. Munguva yekupisa, kaolin inoora kuti igadzire mullite, ichiumba chimiro chikuru chesimba remuviri. Izvi zvinogona kudzivirira kushanduka kwechigadzirwa, kuwedzera tembiricha yekupisa, uye zvakare kupa muviri mwero wakati wekuchena. Panguva imwecheteyo, kaolin ine plasticity yakati, kubatana, kumisa uye kugona kubatana, izvo zvinoita kuti porcelain ivhu uye porcelain glaze zvive zvakanaka, zvichiita kuti porcelain ivhu rive rakanaka pakutenderera, kugadzira uye kugadzira. Kana ikashandiswa muwaya, inogona kuwedzera insulation uye kuderedza kurasikirwa kwe dielectric.

Zvigadzirwa zveCeramics hazvina chete zvinodiwa kuti zvive nyore kugadzira plasticity, kunamira, kuoma, kusimba kwekuomesa, kuoma, hunhu hwekusvira, kudzivirira moto, uye kuchena kwekaolin mushure mekupiswa, asiwo zvine hunhu hwemakemikari, kunyanya kuvapo kwezvinhu zvakaita sesimbi, titanium, mhangura, chromium, uye manganese, izvo zvinoderedza kuchena kwemushonga mushure mekupiswa uye zvinogadzira mavara.
Chinodiwa kuti kaolin ive nehukuru hwezvidimbu zvidiki kazhinji ndechekuti kana yakapfava iri nani, kuitira kuti porcelain dope ive nepurasitiki yakanaka uye simba rekuomesa. Zvisinei, kune maitiro ekukanda anoda kukurumidza kukanda, kukurumidza kukwesha, uye kukurumidza kushaya mvura, zvakakosha kuwedzera saizi yezvidimbu zvezvinoshandiswa. Pamusoro pezvo, mutsauko mukristaro yeKaolinite mu kaolin uchakanganisawo zvakanyanya mashandiro etekinoroji emuviri weceramic. Nekristaro yakanaka, purasitiki uye kugona kwekubatanidza zvichave zvishoma, kuomesa kuchava kudiki, tembiricha yekupisa ichave yakakwira, uye huwandu hwekusachena huchadzikirawo; Kusiyana neizvi, purasitiki yayo yakakwira, kuomesa kushoma, tembiricha yekupisa yakaderera, uye huwandu hwekusachena hunoenderana hwakawedzerawo.
