Te tohatoha rahi o te matūriki
Ko te tohatoha rahi matūriki e pā ana ki te ōwehenga (e whakaatuhia ana i roto i te ōrau o te ihirangi) o ngā matūriki i roto i te kaolin tūturu i roto i tētahi whānuitanga o ngā rahi matūriki rerekē tonu (e whakaatuhia ana i roto i te rahi mata o ngā mirimita, ngā maikiromita rānei). He mea nui ngā āhuatanga tohatoha rahi matūriki o te kaolin mō te whiriwhiri me te tono tukatuka o ngā konganuku. He pānga nui tōna rahi matūriki ki tōna kirihou, te matotoru paru, te kaha whakawhiti katote, te mahi hanga, te mahi whakamaroke, me te mahi sintering. Me tukatuka hangarau te konganuku kaolin, ā, ko te ngāwari ki te tukatuka ki te pai e hiahiatia ana kua noho hei paerewa mō te aromatawai i te kounga o te konganuku. He whakaritenga motuhake mō te rahi matūriki me te pai o ia tari ahumahi mō ngā whakamahinga rerekē o te kaolin. Mena e hiahiatia ana e te United States kia iti iho i te 2 μ te kaolin hei paninga, ko te ihirangi m he 90-95%, ā, ko te whakakī pepa he iti iho i te 2 μ Ko te ōwehenga o te m he 78-80%.

Kirihoutanga
Ka taea e te uku i hangaia mā te whakakotahitanga o te kaolin me te wai te whakapohehe i raro i te kaha o waho, ā, i muri i te tango atu i te kaha o waho, ka taea tonu e ia te pupuri i tēnei āhuatanga whakapohehe, e kiia nei ko te kirihou. Ko te kirihou te tūāpapa o te tukanga hanga o te kaolin i roto i ngā tinana uku, ā, koinei hoki te tohu hangarau matua o te tukanga. I te nuinga o te wā, ka whakamahia te taupū kirihou me te taupū kirihou hei tohu i te rahi o te kirihou. Ko te taupū kirihou e pā ana ki te ihirangi makuku rohe wai o te rauemi uku kaolin me te tango i te ihirangi makuku rohe kirihou, e whakaatuhia ana hei ōrau, arā, W taupū kirihou=100 (W rohe wai – W rohe kirihou). Ko te taupū kirihou e tohu ana i te kaha hanga o te rauemi uku kaolin. Ka taea te ine tika i te kawenga me te whakapohehe o te pōro uku i te wā e pēhia ana me te kuru ana mā te whakamahi i te mita kirihou, e whakaatuhia ana i roto i te kg · cm. He maha ngā wā, ko te teitei ake o te taupū kirihou, ko te pai ake o tōna kaha hanga. Ka taea te wehewehe i te kirihou o te kaolin ki ngā taumata e whā.

Kaha o te kirihou Taupū kirihou Taupū kirihou
Te kaha o te kirihou>153.6
Te āhua o te kirihou waenga 7-152.5-3.6
Te ngoikore o te kirihou 1-7<2.5

Te Hononga

Ko te herenga e pā ana ki te kaha o te kaolin ki te whakakotahi ki ngā rauemi mata ehara i te kirihou hei hanga i ngā papatipu uku kirihou, ā, he kaha maroke anō hoki. Ko te whakatau i te kaha here ko te tāpiri i te onepu quartz paerewa (me te hanganga papatipu o te 0.25-0.15 te rahi o te matūriki e 70% te rahi, me te 0.15-0.09mm te rahi o te matūriki e 30%) ki te kaolin. Ko te nui o te onepu e mau tonu ana i te pōro uku kirihou me te kaha piko i muri i te whakamaroke ka whakamahia hei whakatau i tōna teitei. Ko te nui ake o te onepu e tāpirihia ana, ko te kaha ake o te kaha here o tēnei oneone kaolin. I te nuinga o te wā, ko te kaolin he kaha te kirihou he kaha hoki te kaha here.

Te mahi whakamaroke
Ko te mahi whakamaroke e pā ana ki te mahi a te paru kaolin i te wā o te tukanga whakamaroke. Kei roto i tēnei ko te mimiti o te whakamaroke, te kaha o te whakamaroke, me te aro ki te whakamaroke.

Ko te whakaitiiti maroke e pā ana ki te whakaitiiti o te uku kaolin i muri i te maroke me te whakamaroke. Ko te uku kaolin ka maroke i te nuinga o te wā i ngā pāmahana mai i te 40-60 ℃ ki te kore e neke ake i te 110 ℃. Nā te tukunga o te wai, ka whakapotohia te tawhiti matūriki, ā, ka taea te whakaitiiti i te roa me te rahinga o te tauira. Ka wehea te whakaitiiti maroke ki te whakaitiiti raina me te whakaitiiti rōrahi, e whakaatuhia ana ko te ōrau o te huringa o te roa me te rahinga o te paru kaolin i muri i te maroke ki te taumaha pumau. Ko te whakaitiiti maroke o te kaolin he 3-10%. Ko te rahi o te matūriki he angiangi ake, ko te nui ake o te horahanga mata motuhake, ko te pai ake o te kirihou, ā, ko te nui ake o te whakaitiiti maroke. Ka rerekē te whakaitiiti o te momo kaolin kotahi i runga i te nui o te wai i tāpirihia.

Ehara i te mea ko ngā uku anake ngā whakaritenga tino pakari mō te kirihou, te piri, te whakahekenga maroke, te kaha maroke, te whakahekenga sintering, ngā āhuatanga sintering, te ātete ahi, me te mā o te kaolin i muri i te tahunga, engari kei roto hoki ngā āhuatanga matū, inā koa te noho mai o ngā huānga chromogenic pērā i te rino, te titanium, te parahi, te chromium, me te manganese, e whakaiti ana i te mā i muri i te tahunga, ka puta he ira.
