Kaolin ivhu risiri resimbi, iro riri ivhu nevhu rakaumbwa zvakanyanya nematombo evhu eboka rekaolinite. Nekuda kwechitarisiko chayo chena uye chakapfava, inozivikanwawo sevhu reBaiyun. Yakatumidzwa zita kubva kuGaoling Village muJingdezhen, Jiangxi Province.

Kaolin yayo yakachena yakachena, yakapfava, uye yakapfava, ine hunhu hwakanaka hwemuviri uye hwemakemikari senge plasticity uye inodzivirira moto. Muumbirwo wayo wezvicherwa unonyanya kuumbwa nezvicherwa zvakaita sekaolinite, halloysite, hydromica, illite, montmorillonite, pamwe nequartz nefeldspar. 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.

Zvicherwa zviri mu kaolin zvakasikwa zvakakamurwa kuita zvicherwa zvevhu uye zvicherwa zvisiri zvevhu. Zvicherwa zvevhu zvinosanganisira zvicherwa zveboka re kaolinite uye montmorillonite shoma, mica, uye chlorite; Zvicherwa zvisiri zvevhu zvinosanganisira feldspar, quartz, uye hydrates, pamwe nezvimwe zvicherwa zvesimbi zvakaita se hematite, siderite, limonite, titanium zvakaita se rutile, uye organic matter senge plant fibers. Chinhu chikuru chinoratidza mashandiro e kaolin zvicherwa zvevhu.

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 mwero wakati wepurasitiki, kunamira, kumisa, uye kugona kubatana, ichipa porcelain dope neglaze kugona kuumbwa zvakanaka, zvichiita kuti ceramic dope body ibatsire muviri wemotokari uye grouting, zvichiita kuti zvive nyore kuumba. 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 hwezvimedu zvekaolin ndechekuti kana yakapfava, saka dope reporcelain rive nepurasitiki yakanaka uye simba rekuomesa. Zvisinei, kune maitiro ekukanda anoda kukurumidza kukanda, kukurumidza kukwesha, uye kukurumidza kushaya mvura, zvakakosha kuwedzera saizi yezvimedu zvezvinoshandiswa. Pamusoro pezvo, mutsauko mukristaro yekaolinite mu kaolin uchakanganisawo zvakanyanya mashandiro e porcelain billets. Kana kristaro iri yakanaka, purasitiki uye kugona kubatana kwakaderera, kuomesa kushoma, tembiricha yekupisa yakakwira, uye huwandu hwekusachena hwadzikirawo; Kusiyana neizvi, purasitiki yayo yakakwira, kuomesa kwadzikira, tembiricha yekupisa yadzikira, uye huwandu hwekusachena hwakaenzana hwadzikirawo.
