2021 Te Pūngao Rererangi Kounga Teitei - Ngā Āhuatanga o ngā Pūngao Kohao o te Pūngao – Kehui

Ngā Aorangi Ko te (Ngā Rauemi Kohuke Whānui kei roto ko te Alumina me te Silica) he hua taha o ngā tipu hiko waro, ā, he porowhita mama, kore mahi, tuwhera kī tonu i te hau, i te hau kore mahi rānei. Ko te tae o te Cenosphere he rerekē mai i te hina ki te tata ki te mā, ā, ko tōna mātotoru he tata ki te 0.4 – 0.8 g/cm3 (0.014 – 0.029 lb./cu in), e whakarato ana i te kaha ki te pupuhi.
Ka whakamahia ngā cenospheres hei whakakī hanganga māmā i roto i te raima me te kirihou. Ka konatunatua ngā porowhita ki te kapia hei hanga pahuka honohono māmā hei rauemi matua mō ngā panera hanawiti, ngā poraka taputapu, me te pahuka pōtae. Ka whakamahia ēnei hei hanga pereki ātete wera me ngā paninga uku he iti te kawe wera. Ka tāpirihia ngā cenospheres pania-whakarewa ki ngā peita tiaki EMI.

Ngā Āhuatanga o ngā Cenospheres (e kiia ana hoki Ngā Porowhita Matotoru):

1. He pai te rere: Ko ngā porowhita moroiti tuwhera he porowhita moroiti tuwhera, ko te diameter o te matūriki he 0.2µm-400µm, ā, ko te tere porowhita he ≥95%, e whakanui ana i te rere o te rauemi kua whakakīia, ā, e pai ake ai te rauemi kua whakakīia mō te tukatuka.
2. Kiato iti: ko te kiato hua o ngā porowhita moroiti tuwhera he 0.4g/cm3 -0.8g/cm3. Ki te whakaritea ki te nuinga o ngā rauemi kohuke whenua, he 30%-85% te mama ake o ngā porowhita moroiti tuwhera.
3. Te Tere Whakakī Teitei: Ko ngā porowhita moroiti tuwhera te mea iti rawa te horahanga o te mata hei whakakī. Nā tōna hanganga porowhita, ka tino heke te matotoru.
4. Kaha rawa: ka taea e ngā porowhita moroiti tuwhera te tu atu i te 4000 kg/cm nā te mārō o te anga.
Te kaha pēhi mai i te 3 ki te 7000 kg/cm3.
5. He iti te whakaiti: Ko ngā pirepire poka tētahi o ngā rauemi ruarua i roto i te mara whakakī ka taea te whakatutuki i te iti o te whakaiti. Ko te tere whakaiti o te maha o ngā porowhita moroiti poka kua whakakīia.
6. Te whakamarumaru wera me te ārai haruru: Nā te āhuatanga tuwhera ka iti te kawe wera o ngā moroiti tuwhera, ā, ka taea te whakamahi mō te ārai wera me ngā rauemi ārai haruru.
7. Pūmautanga kaha: ka taea te tāpiri i ngā porowhita moroiti tuwhera ki ngā whakarewa, ngā matū waro, te wai, ngā waikawa, ngā kawakore rānei, me te kore e whakarerekē i ō rātou āhuatanga matū.
8. Ātete pāmahana teitei: Nā te mea he teitei te ira rewa o ngā porowhita moroiti tuwhera ki te 1450°C, ka taea te noho pumau i ngā pāmahana teitei neke atu i te 1000°C.
9. Te ārai hiko: Whakamahia ngā pana hiko, ngā papa taputapu, me ngā rauemi takai hiko hei whakapai ake i te ārai.
10. Utu iti: Ko te utu o ngā porowhita iti tuwhera he 50%-200% iti iho i te utu o ngā porowhita iti horihori.
