I roto i te mahi ahumahi, ka whakapotohia te roa o te ora o ngā taputapu e te pakū, te pāmahana teitei, me te waikura matū, ā, ka whakararu hoki i te whai huatanga.pereti arai alumina—i hangaia mai i te Al₂O₃ tino parakore, ā, i whakamahanatia ki te pāmahana neke atu i te 1700°C—ka whakatau i ēnei āhuatanga uaua. Me te pakeke Rockwell o te 80-90 HRA me te ātete kakahu 266 ngā wā i te maitai manganese, kua noho hei mea matua puta noa i ngā ahumahi nui. Kei raro nei ōna tono matua me te take he haumi whakaaro nui mō ngā pakihi e whai ana ki te tapahi i ngā utu me te whakanui ake i te pumau.
1. Ngā Taupānga Ahumahi Matua
He tino pai ngā pereti arai konumohe i roto i ngā taiao uaua, ā, he mea nui rawa atu i roto i ngā wāhanga e tu atu ana ngā taputapu i te waku tonu, te pānga, te wera nui rānei. Anei ō rātou whakamahinga matua:
Te Ahumahi Hiko me te Waro Wera
Ka pāngia ngā paipa kawe waro, ngā mea whakapūpū, me ngā paipa pungarehu rere i roto i ngā tipu hiko wera me ngā maina e te pakaru nui mai i ngā matūriki waro. Ka pakaru ngā arai whakarewa tuku iho i roto i ngā marama, ka nui te utu mō te kore mahi. Ka roa ake te ora o ngā wāhanga e ngā arai konumohe tae atu ki te 10 ngā wā, ka taea ai te mahi tonu mō ngā tau. Ka pai hoki te ātete ki te pāmahana teitei 1700°C ki ngā pūnaha poiha me ngā awa tuku pungarehu.
Ngā Rāngai Rino, Sima me te Keri
I roto i te hanga maitai, ka tiakina e ngā arai alumina ngā pū kōhao oumu pupuhi, ngā koko, me ngā waha o te kaitahuri mai i te rino rewa me te waikura para, ka roa ake te ora o te mahi mā te 50%+. Mō ngā whare hanga sima me ngā maina, ka whakarārangihia e rātou ngā awaawa, ngā kuru, me ngā mira huri, hei tiaki i a rātou mai i te pānga o te konganuku me te kinker. Ka whakaitihia e ngā paipa maina kua whakarārangihia ki te alumina te kakahu, ka ārai i ngā turuturu me te whakanui ake i te rere o te wai.
Ngā Ahumahi Matū me te Karāhe
Ka whakawhirinaki ngā tipu matū ki ngā arai alumina mō ngā papu, ngā oko tauhohenga, me ngā paipa e whakahaere ana i ngā waikawa waikura, ngā turanga, me ngā paru. Ka ātete rātou ki te waikawa whanariki kukū me ētahi atu mea kino, ka karo i ngā turuturu me te poke o ngā hua. I roto i te hanga karāhe, nā te ātete wera 1600°C e pai ai mō ngā arai oumu, te tiaki i ngā taputapu me te whakarite i te kounga karāhe pumau.
Ngā Whakamahinga Motuhake
Haunga ngā ahumahi matua, ka whakamahia ngā pereti alumina parakore-teitei (99% Al₂O₃) i roto i ngā koti ātete matā hōia (tiakitanga Taumata 3-6) me ngā waka ārai—nā te hoahoa māmā e whakarei ake ana i te whakamarie me te kore e whakararu i te haumaru. I roto i ngā whare whakarewa, ka whakarārangihia e rātou ngā awaawa me ngā oko whakarewa, ka tu atu ki te ūkui whakarewa rewa me te whakau i ngā tukanga whakarewa.
2. Ngā Painga Matua mō tō Pakihi
Ka tukuna e ngā pereti arai alumina he uara tūturu:
- Te roa o te ora:Ka whakaroa ake i te ora o ngā taputapu mō te 5-10 ngā wā ka whakaritea ki ngā rauemi tuku iho, ka whakaiti i ngā utu whakakapinga.
- Ngā Penapena Utu:Ka whakaiti i te wā kore mahi tiaki me ngā whakapaunga mahi.
- Ngā āhuatanga maha:Ātete ki te kakahu, ki ngā pāmahana teitei, ki te waikura, me te pānga o te hihi UV.
- Tāutanga Māmā:E wātea ana i roto i ngā matotoru 6mm-50mm me ngā āhua ritenga (hexagonal, pewa), ka taea te tāuta mā te here, te whakapuru, te whakamomona rānei.
- Haumaru Taiao:Ka whakaiti i te turuturu me te para o ngā rauemi.
3. Hoa Mahi mō ngā Otinga Whakaritenga
Ahakoa kei roto koe i te pūngao, te maitai, te keri, te matū, te haumarutanga rānei, ka tutuki i ā mātou pereti arai alumina kounga teitei—i hangaia mā te hangarau sintering matatau—ō hiahia ahurei. Whakapā mai ki a mātou i tēnei rā hei whakapai ake i te roa o ngā taputapu, hei whakaiti i ngā utu, hei whakanui ake hoki i te pai o te mahi.
