Gaoling rock inokosha zvikuru isiri-metallic mineral.Iyo kaolin inogadzirwa nekupwanya, kukuya uye calcination ine nhevedzano yezvinhu zvakanakisa, uye yakashandiswa zvakanyanya mumaindasitiri mazhinji, kunyanya muindasitiri yekupfeka.Parizvino, mutengo wezvakajairwa calcined kaolin zvigadzirwa wakadzikira, asi simba rekuvhara rayo harina kunaka, iro rinomisa kushandiswa kwayo mumunda wepamusoro-giredhi coatings.Iyo inoratidzwa kuti nekuwedzera kwekukura kwechikamu, simba rinovhara re calcined kaolin rinowedzera zvishoma nezvishoma, chikonzero chikuru ndechekuti iyo yakatsetseka yekaolin particles, iyo yakakura yekuvhara simba.Kaolin kugayachigadzirwa chekugadzira chinoshandiswa kugadzira 300-1250 Ultra yakanaka kaolin kuvandudza simba rekuvhara.Ndezvipi zvakanakira zvayo?Nhasi nekugadzira kaolin chigayoGuilin Hongcheng kwauri sumo yakadzama.

Mushure mekupwanya, kukuya uye superrefining, 850 ℃ calcination, iyo inopa inoshanda referensi yekushandisa uye yakadzika kugadzirisa kwemarasha system kaolin.Nekuda kwekukwira kwayo kwesilicon nealuminium, kaolin haina kusimba uye inonetsa kupfeka.Inodiwa kuti ive yakanaka (325 mesh sieve 5% ~ 10%), uye yakajairwa Raymond chigayo hachikwanise kuwana goho repamusoro pahwaro hwekunaka uku.
