He rauemi whakamarumaru wera-teitei kounga teitei te paraikete muka uku, e whakamahia whānuitia ana i roto i ngā oumu ahumahi, ngā oumu, ngā poiha, te whakamarumaru paipa, me te arai taputapu wera. Mena kei te rapu koe i ngā otinga whakamarumaru wera pakari, tera pea ka pōhēhē koe i ngā momo me ngā momo paraikete muka uku. Mā te ako i ngā rerekētanga matua i waenga i ia tauira ka āwhina i a koe ki te whiriwhiri i te paraikete muka uku tika mō tō pāmahana mahi me ngā tono ahumahi.

Ko ngā rerekētanga matua o ngā momo paraikete muka uku e aro ana ki te ātete pāmahana teitei, te tauira rauemi mata, te kiato papatipu, te kawe wera, te whakaheke pāmahana teitei, me te kaha kume. Ko ngā momo matua ko te 1260°C te paerewa, te 1280°C te parakore teitei, te 1360°C te alumina teitei, me te 1430°C te zirconia te muka uku. He mea hanga ia momo mō ngā āhuatanga mahi pāmahana teitei motuhake.

Ko te paraikete muka uku paerewa 1260°C te kōwhiringa tino whai hua. He mea hanga ki te muka silicate konumohe noa, he mama, he iti te kawe wera, ā, he pumau te mahi whakamarumaru wera. He tino pai mō ngā oumu ahumahi tikanga, ngā arai oumu pāmahana iti me te pāmahana waenga, me te whakamarumaru wera whānui i raro i te 1000°C. Mō ngā kaupapa whakamarumaru ahumahi utu iti, ko te paraikete muka uku paerewa te whiringa pai rawa atu.

Ko te paraikete muka uku parakore 1280°C e whakamahi ana i ngā rauemi mata parakore teitei me te iti ake o ngā poke. He pai ake te ātete ki te waikura, he iti ake te whakaheke i te pāmahana teitei, ā, he roa ake te ora ratonga i te taumata paerewa. He mea whakamahi noa tēnei paraikete muka uku parakore teitei i roto i ngā taputapu whakarewa, te whakamahana matū, me te arai oumu ahumahi pāmahana-waenga.

He nui ake te ihirangi alumina o te paraikete muka uku teitei 1360°C, e tautoko ana i te ratonga roa tae atu ki te 1300°C. He tino pai te pumau i te pāmahana teitei, te kaha kume nui, me te pānga whakamarumaru wera pai rawa atu. He pai te paraikete muka uku teitei alumina mō ngā oumu uku, ngā oumu ahumahi pāmahana teitei, me ngā taiao whakapuru ātete kino.

Ko te paraikete muka uku zirconia 1430°C kei roto i te taumata whakamātao teitei. Mā te tāpiri i te zirconia ki te tauira, ka taea e ia te tu atu i te pāmahana tino teitei tae atu ki te 1350°C, ā, he ātete ki te waikura, he iti noa te whakahekenga wera, ā, he pumau te mahi mō te wā roa. He whānuitia te whakamahinga i roto i ngā oumu matū hinu, rererangi, me ngā oumu ahumahi nui tino teitei.

Whakataurite i te Tohu o te Paraikete Muka Uku

Ngā Kōwhiringa Matotoru me te Kiato

Haunga ngā taumata pāmahana, he rerekē anō hoki te mātotoru me te matotoru o ngā paraikete muka uku. Ko ngā mātotoru noa ko te 96kg/m³, 128kg/m³ me te 160kg/m³; ko te matotoru noa kei waenga i te 10mm ki te 50mm. Ko te mātotoru teitei ake he pai ake te kaha o te hanganga me te iti ake o te ngaronga wera.

I te wā e whiriwhiri ana i te paraikete muka uku, me whakataurite te taumata ki tō pāmahana tuturu, ki te taiao mahi me te tahua. Ka tukuna e mātou he paraikete muka uku raupapa-katoa me ngā whakaritenga katoa, te kounga pumau me ngā rahi kua whakaritea mō ngā kaihoko whakamarumaru ahumahi o te ao.
