Te kirikiri kirikiri
Ngā āhuatanga
• Te hanganga o nga waahanga rite
• Te tohatoha rahi o te witi me te urunga hau
• Te whakakorikori teitei (1825°C)
• He kaha te atete ki te kakahu, te kuru me te ru werawera
• He iti te roha wera
• He pai te rere me te whakaki i te pai na te mea he porowhita
• Ko te reeti whakamohiotanga teitei rawa atu i roto i te punaha kirikiri

Whakaahuatanga
Te kirikiri kirikiri - te otinga tino pai mo o hiahia hangahanga.Ko tenei hua hou e mohiotia ana he ceramsite, cerabeads, ceramcast ranei, a he mea hanga mai i te bauxite calcined e hoatu ana he ahua pai o te witi porohita.Na te nui o te waikura konumohe me te waikura silicon, kei te whakanuia te kirikiri kirikiri i nga taonga pai ake ki te kirikiri kirikiri tikanga.
He maha nga painga o te kirikiri kirikiri mo te kirikiri kirikiri.Tuatahi, he nui ake te ahua o te refractoriness, he pai mo te whakamahi i nga tono wera-teitei.He iti ano te roha waiariki, kia mau tonu te hanga kirikiri, te hanga matua me te rite tonu ahakoa te wera nui.
I tua atu i tona kaha whakamīharo, he pai te rere o te kirikiri kirikiri - ma tenei ka taea te hanga me te hanga i roto i te mahi whakarewa.I tua atu, he nui te parenga o te kirikiri kirikiri ki te kakahu, ki te kuru, ki te wiri waiariki, na reira ko te whiriwhiri pai mo nga momo tono whakarewa katoa.
Ko tetahi atu painga nui mo te whakamahi i te kirikiri Karamic Foundry ko te mea he nui te utu whakaora, te tikanga ka ngawari te whakamahi ano i roto i te mahi whakarewa.Ko tenei, ka awhina i te whakaiti i te ururua me te whakaiti i nga utu.
I roto i te katoa, ko te Foundry Ceramic Sand he mea tika mo nga whare hangahanga e rapu ana ki te whakapai ake i o raatau mahi whakarewa.Na ona taonga pai me te kaha o te kaha, he painga nui ki runga i te kirikiri kirikiri tuku iho.
