Ngā Pōro Huri Arumina
Hei reo huri uku mahi kounga teitei, ko tā mātouNgā Pōro Huri Aruminahe mea hanga hei whakarato i te mahi tino pai i roto i te huri, te kuru, me te whakamarara puta noa i ngā rāngai ahumahi kanorau. He mea hanga ki te waikura konumohe parakore teitei (Al₂O₃) hei wāhanga matua me te hangarau sintering uku matatau, e tu ke ana ēnei pōro mō tō rātou pakeke pai rawa atu, te ātete ki te kakahu, me te pumau matū, koia te mea tuatahi hei whiringa mō te tukatuka rauemi whai hua me te tika.
1. Whakarōpūtanga mā te Ihirangi Alumina
(1) Pōro Konumohe-Waenga (60%-65% Al₂O₃):He kōwhiringa utu-pai mō ngā mahi huri whānui. He pai mō te huri i ngā rauemi he iti te pakeke, pērā i te paru waro, ngā maniua, me ngā kohuke noa. He pai mō ngā kiritaki e rapu ana i ngā otinga mahi taurite me te utu iti.
(2) Pōro Konumohe Waenga-Teitei (75%-80% Al₂O₃):He ātete ki te kakahu, he pai ake te whakataurite ki ngā pōro konumohe-waenga. He whānuitia te whakamahinga mō te huri i ngā rauemi mata uku, ngā rauemi hanga, me ngā hua matū iti-waikura. He kōwhiringa maha mō te huri ahumahi mahi-waenga.
(3) Ngā Pōro Konumohe-Teitei (≥90% Al₂O₃):He kounga teitei me te mahi whānui tino pai. Ka wehea anō ki ngā papa raro 90-uku, 92-uku, 95-uku, me te 99-uku. I roto i ēnei, ko ngā pōro 92-uku te mea tino rongonui nā te mea he pai te taurite o te mahi me te utu, ā, he whānui te whakamahinga i roto i te huri pai o ngā karaihe uku, ngā rauemi hiko, me ngā rauemi mata matū tino parakore. Ko ngā pōro 99-uku, me te ihirangi alumina teitei rawa, he mea hanga mō te huri tino tika i roto i ngā ahumahi teitei pēnei i te semiconductor me te rererangi.
2. Ratonga Whakaritenga
E mārama ana mātou he rerekē ngā hiahia huri a ngā kiritaki. Hei whakatutuki i ō hiahia motuhake, ka tukuna e mātou he ratonga whakaritenga whānui:
Te ihirangi alumina ritenga kia rite ki tō taiao huri me ngā āhuatanga o te rauemi.
Ngā rahi ritenga (mai i te 1mm ki te 50mm) me ngā āhua (porowhita, porotakaroa, me ētahi atu).
Maimoatanga mata motuhake hei whakanui ake i te ātete ki te kakahu, hei whakaiti rānei i te parahanga.
Ngā otinga tākai ritenga (tākai papatipu, tākai putea, me ētahi atu) hei whakahaere i te kawe me te rokiroki.
Ngā Āhuatanga:
Te pakeketanga teitei me te ātete kaha ki te kakahu:Ka eke te pakeke Mohs ki te 9 (tata ki te taimana), me te tere pakaru iti (<0.03%/1,000 hāora mō ngā tauira parakore teitei). Ka ātete ki te pakarukaru me te paru i te wā e huri roa ana, ka roa te ora mahi.
Teitei o te Kiato me te Pai o te Huri:Ko tōna mātotoru papatipu he 3.6-3.9 g/cm³, ā, he kaha te pānga me te kutikuti e tukuna ana i te wā e huri ana, e tere ana te whakapai ake i ngā rauemi ki te taumata maikorona, me te whai huatanga 20%-30% teitei ake i ngā pōro konumohe kounga waenga me te kounga iti.
Ngā poke iti me te pumau matū:Ko ngā tauira parakore teitei he iti iho i te 1% ngā poke (pērā i te Fe₂O₃), ā, ka ārai i te poke o ngā rauemi. He ātete ki te nuinga o ngā waikawa me ngā kawakore (haunga ngā waikawa kaha me ngā kawakore kukū), he pāmahana teitei (neke atu i te 800°C), ā, he pai mō ngā momo pūnaha huri.
Ngā Rahi Ngāwari me te Hototahi:Kei te wātea mai i ngā diameters mai i te 0.3 ki te 20 mm, ka taea te whakamahi i te pōro i ngā rahi takitahi, i ngā rahi whakauru rānei, e hototahi ana ki ngā mira pōro, ki ngā mira onepu, me ētahi atu taputapu, e tutuki ai ngā hiahia katoa mai i te huri mata ki te huri pai.
