Kaolin is a non-metallic mineral, inova rudzi rwevhu nevhu dombo rinonyanya kuumbwa neboka reKaolinite ivhu zvicherwa.Nekuda kwekuchena kwayo uye kutetepa kutaridzika, inozivikanwa zvakare seBaiyun ivhu.Inotumidzwa zita reGaoling Village muJingdezhen, Jiangxi Province.

Yayo yakachena kaolin ichena, yakapfava uye Mollisol senge, ine yakanaka plasticity, moto kuramba uye zvimwe zvemuviri uye makemikari zvinhu.Kuumbwa kwayo kwemaminerari kunonyanya kuumbwa neKaolinite, halloysite, hydromica, Illite, Montmorillonite, quartz, feldspar uye mamwe maminerari.Kaolin inoshandiswa zvakanyanya mukugadzira mapepa, ceramics, uye refractory zvinhu, inoteverwa neaya, mafirita erabha, enamel glaze, uye chena simende zvinhu.Mari shoma inoshandiswa mupurasitiki, pendi, pigment, mavhiri ekukuya, mapenzura, zvizorwa zvemazuva ese, sipo, mishonga yekuuraya zvipembenene, mishonga yemishonga, machira, peturu, makemikari, zvekuvaka, kudzivirira kwenyika, uye mamwe maindasitiri.
Kaolin rave rinokosha chicherwa mbishi zvinhu zvakawanda maindasitiri akadai papermaking, Ceramics, rabha, kemikari engineering, coatings, mishonga, uye nyika kudzivirira.

Indasitiri yeceramic ndiyo yekutanga uye inonyanya kushandiswa indasitiri yekushandiswa kwekaolin.Iyo yakawanda dosage ndeye 20% kusvika 30% yeformula.Basa re kaolin mumakeramics nderokuzivisa Al2O3, iyo inobatsira pakuumbwa kwemullite, inovandudza kugadzikana kwemakemikari uye sintering simba.Munguva yekupisa, kaolin inoora kuita mullite, ichigadzira chimiro chikuru chekusimba kwemuviri.Izvi zvinogona kudzivirira deformation yechigadzirwa, kuwedzera kupisa kwekupisa, uye zvakare kupa muviri imwe dhigirii yekuchena.Panguva imwecheteyo, kaolin ine mamwe mapurasitiki, kubatana, kumiswa uye kugona kwekubatanidza, izvo zvinopa ivhu revhu uye porcelain glaze nekuumbwa kwakanaka, zvichiita kuti muviri wevhu wevhu ugone kutendeuka, kumera uye kuumba.Kana yakashandiswa muwaya, inogona kuwedzera kuvharidzira uye kuderedza dielectric kurasikirwa.

Ceramics haingove nezvinodiwa zvakasimba zvepurasitiki, kunamatira, kuomesa shrinkage, kuomesa simba, sintering shrinkage, sintering properties, kudzivirira moto, uye post firing whiteness ye kaolin, asiwo zvinosanganisira zvinhu zvemakemikari, kunyanya kuvapo kwezvinhu zvechromogenic zvakadai sesimbi, titanium, mhangura, chromium, uye manganese, izvo zvinoderedza kuchena kwemashure uye kuburitsa mavara.
Chinodiwa chekukura kwekaolin kazhinji ndechekuti iyo yakatsetseka ive nani, kuitira kuti madhaka eporcelain ave nepurasitiki yakanaka uye kuomesa simba.Nekudaro, kune yekukanda maitiro ayo anoda kukurumidza kukanda, kukurumidza grouting kumhanya, uye kupera simba kwemvura, zvinodikanwa kuwedzera saizi yezvikamu.Mukuwedzera, kusiyana kwekristallinity yeKaolinite mu kaolin ichaitawo zvakanyanya kushanda kwekombiyuta yemuviri weceramic.Nekristini yakanaka, iyo plastiki uye kukwanisa kusungirirana kuchava kwakaderera, kuomeswa kwe shrinkage kuchava kuduku, kutonhora kwekupisa kuchave kwakakwirira, uye kusvibiswa kwehutsvina kuchaderedzwawo;Pane zvinopesana, mapurasitiki ayo akakwirira, kuomesa shrinkage yakakura, sintering tembiricha yakaderera, uye inoenderana netsvina yemukati zvakare yakakwirira.
