Ngā Porowhita Karāhe Kohao Ngā Rauemi Whakamarumaru Ngā Pīra Karāhe Kohao Ngā Porowhita Karāhe Kohao Hei Hoko
Whakaahuatanga Hua
Ko ngā porowhita iti o te karāhe tuwhera he mea hanga ki te paura ma, he mea tino māmā, he mea kore-whakarewa, he momo rauemi māmā hou kua whakawhanakehia i ngā tau tata nei, he whānui te whakamahinga me te mahi tino pai. Ko tōna wāhanga matua he karāhe borosilicate raima houra, he matotoru tūturu o te 0.20-0.76g/cm³ me te rahi matūriki o te 2-130μm.
He maha ngā āhuatanga pai o te hanganga porowhita angiangi ahurei o ngā porowhita karāhe tuwhera:
1. Tino iti te mātotoru, he iti ake te utu rōrahi;
2. Te kaha kōpeketanga isostatic teitei hei whakatutuki i ngā whakaritenga o ngā tikanga tukatuka rerekē;
3. Ka taea e te porowhita teitei me te pānga peera pōro te whakapai ake i te rere;
4. He iti te horahanga mata motuhake, he iti te mimiti hinu, ā, he nui te kaha whakakī;
5. He iti te kawe wera, he pai te pānga whakamahana wera;
6. He iti te pūmau dielectric, he pai te mahi whakamahana;
7. Te pumau matū, kāore e wairewa i roto i te nuinga o ngā waikawa me ngā kawakore;
8. He āhua motuhake, kia tino pumau ai te āhua o te hua.
