Uyazi ukuthi umbala we-ceramic surface ukhiqizwa kanjani?

Kumelwe ukuba uzibonile izitsha zobumba ezinemibala ehlukahlukene. Nokho, ingabe uyazi ukuthi kungani izitsha zobumba zingaveza zonke izinhlobo zemibala emihle?

Eqinisweni, izitsha zobumba ngokuvamile zine “glaze” ecwebezelayo futhi ebushelelezi ebusweni bazo.

I-glaze yenziwe ngezinto zokusetshenziswa zamaminerali (njenge-feldspar, i-quartz, i-kaolin) kanye nezinto zokusetshenziswa zamakhemikhali ezixutshwe ngesilinganiso esithile futhi zigaywe kahle zibe uketshezi oludaka, olufakwe ebusweni bomzimba we-ceramic.Ngemuva kwezinga lokushisa elithile le-calcining nokuncibilika, lapho izinga lokushisa lehla, lenza ungqimba oluncane lwengilazi ebusweni be-ceramic.

Eminyakeni engaphezu kuka-3000 edlule, abantu baseShayina base befunde ukusebenzisa amatshe nodaka ukwenza ama-glaze ukuhlobisa izitsha zobumba.Kamuva, abadwebi be-ceramic basebenzise isenzakalo somlotha kahhavini owela ngokwemvelo emzimbeni we-ceramic ukuze wenze i-glaze, base besebenzisa umlotha wezitshalo njengento eluhlaza yokwenza i-glaze.

I-glaze esetshenziswa ekukhiqizeni izitsha zobumba zansuku zonke ihlukaniswe i-lime glaze kanye ne-feldspar glaze. I-Lime glaze yenziwe ngetshe elicwebezelayo (i-mineral material eluhlaza yemvelo) kanye ne-lime-flyash (ingxenye eyinhloko i-calcium oxide), kuyilapho i-feldspar glaze ikakhulukazi yakhiwe nge-quartz, i-feldspar, imabula, i-kaolin, njll.

Ukwengeza ama-oxide ensimbi noma ukungena kwezinye izingxenye zamakhemikhali ku-lime glaze naku-feldspar glaze, futhi kuye ngezinga lokushisa lokudubula, imibala ehlukahlukene ecwebezelayo ingakhiwa.Kukhona i-cyan, emnyama, eluhlaza okotshani, ephuzi, ebomvu, eluhlaza okwesibhakabhaka, ensomi, njll.I-porcelain emhlophe icwebezela esobala elicishe lingabi nambala. Ngokuvamile, ugqinsi lwecwecwe le-ceramic lomzimba lingamasentimitha angu-0.1, kodwa ngemva kokukhishwa kuhhavini, lizoba inamathela ngokuqinile emzimbeni we-porcelain, okwenza i-porcelain iminyene, icwebezele, futhi ithambe, ingangeneki emanzini noma ikhiphe amagwebu, inikeze abantu umuzwa okhanya njengesibuko.Ngesikhathi esifanayo, kungathuthukisa ukuqina, kuvimbele ukungcola, futhi kube lula ukuhlanza.
