Ukusabalalisa usayizi we-particle
Ukusabalalisa usayizi wezinhlayiyana kubhekisela engxenyeni (evezwa ngokuqukethwe kwephesenti) yezinhlayiya ze-kaolin yemvelo ngaphakathi kwebanga elinikeziwe lobukhulu obuhlukahlukene bezinhlayiyana (okuvezwa ngosayizi wemeshi wamamilimitha noma ama-micrometer).Izici zokusabalalisa usayizi wezinhlayiyana ze-kaolin zibaluleke kakhulu ekukhetheni nasekusetshenzisweni kwenqubo yensimbi.Ubukhulu bayo bezinhlayiyana bunomthelela omkhulu epulasitiki yayo, i-viscosity yodaka, umthamo wokushintshanisa i-ion, ukusebenza kokubumba, ukusebenza kokumisa, nokusebenza kwe-sintering.I-Kaolin ore idinga ukucutshungulwa kobuchwepheshe, futhi ukuthi kulula yini ukucutshungulwa ibe yinhlawulo edingekayo isibe ngesinye sezindinganiso zokuhlola ikhwalithi yensimbi.Umnyango ngamunye wezimboni unosayizi othize wezinhlayiyana kanye nezidingo zokucoleka ukuze kusetshenziswe i-kaolin ehlukene.Uma i-United States idinga i-kaolin esetshenziswa njenge-coating ibe ngaphansi kuka-2 μ Okuqukethwe kuka-m kubala u-90-95%, futhi isigcwalisi sokwenza iphepha singaphansi kuka-2 μ Ingxenye ye-m ingama-78-80%.

Ipulasitiki
Ubumba olwakhiwe inhlanganisela ye-kaolin namanzi lungakhubaza ngaphansi kwamandla angaphandle, futhi ngemva kokususwa kwamandla angaphandle, lusengakwazi ukugcina le mpahla yokuguquguquka, ebizwa ngokuthi i-plasticity.Ipulasitiki iyisisekelo senqubo yokwakhiwa kwe-kaolin emizimbeni ye-ceramic, futhi iyinkomba yezobuchwepheshe eyinhloko yenqubo.Ngokuvamile, inkomba ye-plasticity kanye ne-plasticity index isetshenziselwa ukumela ubukhulu bepulasitiki.I-plasticity index ibhekisela emkhawulweni woketshezi wokuqukethwe komswakamo wento yobumba lwe-kaolin kukhishwe umkhawulo wepulasitiki wokuqukethwe komswakamo, ovezwa njengephesenti, okungukuthi, W plasticity index=100 (W umkhawulo woketshezi - W umkhawulo wepulasitiki).Inkomba ye-plasticity imelela ukwakheka kwezinto zobumba ze-kaolin.Umthwalo kanye nokuguqulwa kwebhola lobumba ngesikhathi sokucindezela nokuchotshozwa kungalinganiswa ngokuqondile kusetshenziswa imitha yepulasitiki, evezwe ngo-kg · cm.Ngokuvamile, ukuphakama kwe-plasticity index, ngcono ukubunjwa kwayo.Ipulasitiki ye-kaolin ingahlukaniswa ngamaleveli amane.

Amandla e-Plastiki Inkomba ye-Plastiki Inkomba yepulasitiki
Ipulasitiki eqinile>153.6
Ipulasitiki ephakathi 7-152.5-3.6
Ipulasitiki ebuthakathaka 1-7<2.5<br /> Non plasticity<1<br /> Ukuhlangana

Ukubophezeleka kusho ikhono le-kaolin lokuhlangana nezinto zokusetshenziswa okungezona zepulasitiki ukuze kwakhe ubumba lwepulasitiki futhi ibe namandla athile okomisa.Ukunqunywa kwekhono lokubopha kuhilela ukungeza isihlabathi sequartz esivamile (esinokwakheka kwesisindo esingu-0.25-0.15 kasayizi wengxenyana yezinhlayiyana ezibalelwa ku-70% kanye no-0.15-0.09mm wefraction kasayizi wezinhlayiyana ezibalelwa ku-30%) ku-kaolin.Okuqukethwe kwesanti ephakeme kakhulu lapho isengakwazi ukugcina ibhola lobumba lepulasitiki futhi amandla aguqukayo ngemva kokoma asetshenziselwa ukunquma ubude bayo.Uma kunezelwa isihlabathi esiningi, amandla okuhlanganisa ale nhlabathi ye-kaolin aqina.Ngokuvamile, i-kaolin ene-plasticity eqinile futhi inekhono eliqinile lokubopha.

Ukomisa ukusebenza
Ukomisa kubhekisela ekusebenzeni kodaka lwe-kaolin phakathi nenqubo yokomisa.Lokhu kuhlanganisa ukomisa ukuncipha, amandla okomisa, nokuzwela ukomisa.

Ukomisa ukuncipha kusho ukushwabana kobumba lwe-kaolin ngemva kokuphelelwa amanzi emzimbeni nokomisa.Ubumba lwe-Kaolin ngokuvamile luphelelwa amanzi emzimbeni futhi lomiswe emazingeni okushisa asukela ku-40-60 ℃ kuya ku-110 ℃.Ngenxa yokuphuma kwamanzi, ibanga lezinhlayiyana lifinyezwa, futhi ubude nevolumu yesampula kungaphansi kokuncipha.Ukuncipha kokuncipha kuhlukaniswe ngokuncipha komugqa kanye nokuncipha kwevolumu, okuvezwa njengephesenti loshintsho lobude nomthamo wodaka lwe-kaolin ngemva kokoma kuya esisindweni esingaguquki.Ukuncipha kokumiswa kwe-kaolin ngokuvamile kungama-3-10%.Ubukhulu bezinhlayiya bucolekile, indawo ethile engaphezulu ikhudlwana, ipulasitiki iba ngcono, futhi kuyancipha ukuncipha kokoma.Ukuncipha kohlobo olufanayo lwe-kaolin kuyehluka kuye ngenani lamanzi elingeziwe.

I-Ceramics ayinayo kuphela izidingo eziqinile ze-plasticity, ukunamathela, ukuncipha kokumisa, amandla okomisa, ukuncibilika kwe-sintering, izakhiwo ze-sintering, ukumelana nomlilo, nokukhishwa komlilo okumhlophe kwe-kaolin, kodwa futhi kuhilela izakhiwo zamakhemikhali, ikakhulukazi ukuba khona kwezakhi ze-chromogenic ezifana nensimbi, i-titanium, ithusi, i-chromium, ne-manganese, enciphisa ubumhlophe bokudubula futhi ikhiqize amabala.
