Iyo idiki saizi yechikamu, iyo yakakwirira kuchena.Iyo yakaonda saizi yechikamu ndeye, iyo inonyanya kuoma kubvisa kabhoni, kunyanya kabhoni mukati mechikamu haisi nyore kuvhurika, iyo inokanganisa kuchena kwechigadzirwa chakakarwa.Iyo mbishi yakanaka, nzvimbo yepasi yakakura, kabhoni iri nyore kubvisa, kabhoni iri nyore kunyungudutsa, uye kuchena kwechigadzirwa chakakarurwa kwakakwira.

Mukati mekuita calcining kuchena kwechigadzirwa, kaolin ine inononoka maitiro nekuwedzera kwekupisa kwecalcination.Zvichienzaniswa ne900 ℃, 850 ℃ kaolin calcination, kaolin zvigadzirwa hazvingobvisi mvura yekristaro, kuwedzera saizi yepore, asiwo kuchengetedza kuchena, kuchena kwepamusoro, kuri kwecalcination tembiricha, kuderedza mari yekudyara uye kusvibiswa kwezvakatipoteredza, saka 850 ℃ ndiyo yakanyanya kupisa tembiricha.

Kuchena kwechigadzirwa kunowedzera nekugara kwekushisa nguva, asi maitiro anononoka.Kana tembiricha iri pfupi, kabhoni iri mu kaolin haisi nyore kubvisa.Mushure memaawa anopfuura mana ekupisa nguva dzose, dhigirii ye decarburization uye kupera mvura kwechigadzirwa iduku, saka kuchena kwechigadzirwa kunovandudzwa, asi kuvandudzwa kuduku zvikuru.Kuti uvandudze kushanda kwekushisa, iyo inogara inodzora tembiricha yechigadzirwa che calcined inonyanya kukodzera kwemaawa mana

Nekushandisa akasiyana ekuwedzera ecalcining, maitiro ekugadzira anorerutswa, mutengo unoderedzwa, uye kuchena kwezvigadzirwa zvecalcined kunovandudzwa zvakanyanya.Pakati pavo, sodium chloride ndiyo inonyanya kushanda yekuwedzera.Kuiswa kwe urea se intercalation agent kunowedzerawo kuchena kwe calcined kaolin

Kudzora kwemhepo ye calcination kune simba guru pakuchena uye yellowness yezvigadzirwa zve calcined.Kusangana nezvinodiwa zvekubvisa kabhoni yemarasha akatevedzana kaolin, calcination mu oxidizing mhepo inokonzeresa yakaderera iron oxide uye mutengo wakakwira, izvo zvinozoita kuti kuwedzere kwekubvisa kabhoni uye yellowness yezvigadzirwa zvekaolin.Naizvozvo, calcination pa850 ℃ mukupisa kwepamusoro uye kudzikisira mamiriro ekunze kunogona kuderedza simbi yakaderera uye yakakwira simbi, kudzora mamiriro ecalcination, kuderedza kuchena uye kugadzirisa yellowness yezvigadzirwa.
