Kugawa kukula kwa tinthu
Kugawa kwa tinthu tating'onoting'ono kumatanthauza kuchuluka (komwe kumawonetsedwa mu kuchuluka kwa tinthu tating'onoting'ono) mu kaolin yachilengedwe mkati mwa mitundu yosiyanasiyana ya tinthu tating'onoting'ono (komwe kumawonetsedwa mu kukula kwa mamilimita kapena ma micrometer). Makhalidwe a kugawa kwa tinthu tating'onoting'ono ta kaolin ndi ofunikira kwambiri pakusankha ndi kugwiritsa ntchito njira za ores. Kukula kwa tinthu tating'onoting'ono ta kaolin kumakhudza kwambiri pulasitiki yake, kukhuthala kwa matope, mphamvu yosinthira ma ion, magwiridwe antchito oumba, magwiridwe antchito owuma, ndi magwiridwe antchito oyeretsera. Kaolin imafuna kukonza kwaukadaulo, ndipo ngati ndi yosavuta kuikonza mpaka kusalala kofunikira kwakhala imodzi mwa miyezo yowunikira mtundu wa ore. Dipatimenti iliyonse yamafakitale ili ndi kukula kwa tinthu tating'onoting'ono ndi zofunikira za kusalala kwa kaolin mosiyanasiyana. Ngati United States ikufuna kuti kaolin yogwiritsidwa ntchito ngati chophimba ikhale yochepera 2 μ Zomwe zili mu m zimakhala 90-95%, ndipo chodzaza mapepala ndi chochepera 2 μ Gawo la m ndi 78-80%.

Kusungunuka
Dongo lopangidwa ndi kuphatikiza kwa kaolin ndi madzi limatha kusokonekera chifukwa cha mphamvu yakunja, ndipo mphamvu yakunja ikachotsedwa, imatha kusungabe mawonekedwe a kaolin, omwe amatchedwa plasticity. Plasticity ndiye maziko a njira yopangira kaolin m'mabomba a ceramic, ndipo ndiyenso chizindikiro chachikulu chaukadaulo cha njirayi. Nthawi zambiri, plasticity index ndi plasticity index zimagwiritsidwa ntchito kuyimira kukula kwa plasticity. Plasticity index imatanthauza kuchuluka kwa chinyezi chamadzimadzi cha zinthu zadothi za kaolin kupatula kuchuluka kwa chinyezi cha pulasitiki, komwe kumawonetsedwa ngati peresenti, mwachitsanzo W plasticity index=100 (W liquid limit – W plasticity limit). Plasticity index imayimira kupangika kwa zinthu zadothi za kaolin. Katundu ndi kusintha kwa mpira wadothi panthawi yoponderezedwa ndi kuphwanyidwa kumatha kuyezedwa mwachindunji pogwiritsa ntchito mita ya plasticity, yomwe imawonetsedwa mu kg · cm. Nthawi zambiri, plasticity index ikakwera, imapangika bwino. Plasticity ya kaolin imatha kugawidwa m'magawo anayi.

Kugwirizana

Kulumikizana kumatanthauza kuthekera kwa kaolin kuphatikiza ndi zinthu zopanda pulasitiki kuti apange dongo la pulasitiki ndikukhala ndi mphamvu youma. Kudziwa kuthekera kolumikizana kumaphatikizapo kuwonjezera mchenga wa quartz wokhazikika (wokhala ndi unyinji wa 0.25-0.15 tinthu tating'onoting'ono tomwe timakhala 70% ndi 0.15-0.09mm tinthu tating'onoting'ono tomwe timakhala 30%) ku kaolin. Mchenga wambiri ukatha kusunga mpira wa dongo wa pulasitiki ndi mphamvu yosinthasintha ikauma zimagwiritsidwa ntchito kudziwa kutalika kwake. Mchenga ukawonjezedwa, mphamvu yolumikizana ya dothi la kaolin iyi imakhala yolimba. Nthawi zambiri, kaolin yokhala ndi pulasitiki yolimba imakhalanso ndi mphamvu yolumikizana yolimba.

Kuuma kwa ntchito
Kuuma bwino kumatanthauza momwe matope a kaolin amagwirira ntchito panthawi youma. Izi zikuphatikizapo kuchepa kwa kuumitsa, mphamvu youma, komanso kuuma bwino.

Kuuma pang'ono kumatanthauza kuchepa kwa dothi la kaolin pambuyo pa kutaya madzi ndi kuumitsa. Dothi la Kaolin nthawi zambiri limataya madzi ndi kuumitsa pa kutentha kuyambira 40-60 ℃ mpaka osapitirira 110 ℃. Chifukwa cha kutuluka kwa madzi, mtunda wa tinthu umafupikitsidwa, ndipo kutalika ndi kuchuluka kwa chitsanzocho zimachepa. Kuuma pang'ono kumagawidwa m'magulu awiri: kuchepa kwa mzere ndi kuchepa kwa volumetric, komwe kumawonetsedwa ngati kuchuluka kwa kusintha kwa kutalika ndi kuchuluka kwa matope a kaolin pambuyo pouma mpaka kulemera kosalekeza. Kuuma pang'ono kwa kaolin nthawi zambiri kumakhala 3-10%. Kukula kwa tinthu tating'onoting'ono kukakhala kochepa, malo enieni a pamwamba amakhala okulirapo, ndipo kuuma kumachepa kwambiri. Kuuma pang'ono kwa mtundu womwewo wa kaolin kumasiyana malinga ndi kuchuluka kwa madzi omwe awonjezeredwa.

Zadothi sizimangokhala ndi zofunikira zokhazikika pa pulasitiki, kumatira, kuuma, mphamvu youma, kuuma, mphamvu zouma, kuuma, kukana moto, komanso kuyera kwa kaolin pambuyo poyaka moto, komanso zimakhudzanso mphamvu za mankhwala, makamaka kupezeka kwa zinthu monga chitsulo, titaniyamu, mkuwa, chromium, ndi manganese, zomwe zimachepetsa kuyera pambuyo poyaka moto ndikupanga mawanga.
