Kua whānuitia te whakamahinga o ngā hiko karāhe mana-tino teitei i roto i ngā āhuatanga e whai ake nei:
1. Ngā pokepokea graphite mō te whakarewatanga tonu me te haurua-tonu o ngā konganuku kore-ferrous
I ngā tau tata nei, kua whakatairangahia ngā tikanga whakaputa matatau pēnei i te hanga tonu (tērā rānei he hanga ā-haurua) o ngā pae, ngā ngongo rānei mai i te whenua whakarewa rewa i te kāinga me tāwāhi. Kua tīmata te whakamahi i tēnei tikanga i Haina i roto i ngā āhuatanga pēnei i te parahi, te koranu parahi, te konumohe me ngā koranu konumohe. E kiia ana ko te karāpiti horihori te rauemi tino pai mō ngā pokepoke whakarewa tonu, ā-haurua rānei o ngā konganuku kore-ferrous. Kua whakamātauhia e ngā mahi whakaputa nā te whakamahi i ngā pokepoke karāpiti, he pai te kawe wera (ko te kawe wera te mea e whakatau ana i te tere totoka o ngā konganuku, o ngā koranu rānei) me te pai o te mahi whakahinuhinu-ake o ngā pokepoke, ehara i te mea ka piki ake te tere whakarewa anake, engari nā te tika o te rahi o te inget, he maeneene te mata, ā, he ōrite te hanganga tioata, ka taea te whakahaere tika i te tukanga tukatuka e whai ake nei. Ehara i te mea ka nui ake te hua o ngā hua kua oti, ka whakaiti i te ngaronga o ngā hua para, engari ka tino whakapai ake hoki i te kounga o ngā hua.
E rua ngā momo tikanga whakarewatanga tonu: te whakarewatanga tonu poutū me te whakarewatanga tonu whakapae.
2. Ngā pokepokea ai mō te whakarewanga pēhanga
Kua whakamahia angitu ngā rauemi karāti horihori i roto i te whakarewanga pēhanga o ngā konganuku kore-ferrous. Hei tauira, ko ngā whakarewanga konutea me te konukōre parahi i hangaia mai i ngā pokepokea whakarewa pēhanga i hangaia mai i ngā rauemi karāti horihori kua whakamahia ki ngā wāhanga motuka me ētahi atu āhuatanga.
3. Mate pēhi wera
Ko ngā āhuatanga o ngā mate pēhi wera karāhe horihori e whai ake nei ina whakamahia ana i roto i te sintering pēhanga o te carbide sima:
Tuatahi, ki te whakanuia te pāmahana pēhi ki te 1350-1450 nekehanga, ka taea te whakaiti i te pēhanga e hiahiatia ana ki te 67-100 kirokaramu te kaha mō ia henimita tapawha (arā, te kotahi-tekau o te pēhanga pēhi matao). Tuarua, ka whakahaerehia te pēhanga me te whakamahana i roto i te tukanga kotahi, ā, ka taea te whiwhi i tētahi tinana sintered matotoru i muri i te wā poto o te sintering.
4. Ngā pokepoke mō te hanga karāhe
Nā te pumau matū o ngā rauemi karāhe, tōna ātete ki te makuku i te karāhe rewa, me te kore e whakarerekē i te hanganga o te karāhe, tae atu ki tōna ātete pai ki ngā ru wera me ngā huringa iti o te rahi me te pāmahana, kua noho hei rauemi pokepokea ai e tino hiahiatia ana i roto i te hanga karāhe i ngā tau tata nei. Ka taea te whakamahi hei hanga pokepokea ai mō ngā ngongo karāhe, ngā ngongo tuke, ngā awaawa, me ētahi atu pounamu karāhe āhua motuhake.
5. Ngā mate sintering me ētahi atu
Mā te whakamahi i te iti rawa o te whakarerekētanga wera o ngā rauemi karāpiti horihori, ka taea te hanga i ngā pokepokea ai me ngā whāriki mō ngā transistors. Kua whānuitia te whakamahinga inaianei, ā, kua waiho hei rauemi tino nui mō te whanaketanga o te umanga semiconductor. Hei tāpiri, ka whakamahia hoki ngā pokepokea ai i roto i ngā pokepokea ai rino maka, ngā pokepokea ai pakari mō ngā momo konganuku kore-ferrous, ngā pokepokea ai mō te maitai maka, ngā pokepokea ai mō ngā konganuku ātete-wera (pērā i te titanium, te zirconium, te molybdenum, me ētahi atu), me ngā pokepokea ai mō ngā pokepokea ai aluminothermic mō ngā reera whakarewa, me ētahi atu.
6. Ngā pokepokea graphite mō te whakarewatanga centrifugal
Kua angitu te whakamahi i te karāpeti pokepokea ai i roto i te whakarewatanga porowhita. Kua tangohia e te Hononga o Amerika ngā pokepokea karāpeti horihori he matotoru ake i te 25 mirimita te pakitara mō te whakarewatanga porowhita o ngā ringaringa parahi. Hei ārai i te kino o te mura o ngā pokepokea karāpeti horihori, ka taea te mahi i ētahi mahi ārai-waikura. I muri i te whakarewatanga o ētahi whakarewanga, ki te kitea kua wera te mata o roto o te pokepokea ai, ka taea te whakanui ake i te rahi o te kōhao o roto o te pokepokea ai hei whakamahi mō te whakarewatanga o ngā ringaringa rahi. Ko Qingdao Mingyuan Fengyue New Materials he momo hou o te umanga tukatuka karāpeti me te paura karāpeti maramara kounga teitei hei tinana matua me ngā hua karāpeti hangarau teitei hei hua matua. Kua whakatūria e ia he hononga mahi tahi roa me te neke atu i te 200 ngā waeine o roto me tāwāhi, ā, kua tino whakanuia e te nuinga o ngā kaiwhakamahi.
He mea hanga te paura karāpiti nanomita mai i te karāpiti maori hei rauemi mata, ka tukatukahia mā roto i ngā taputapu motuhake mō te kuru miihini me ngā tikanga whakaputa motuhake. Hei paura karāpiti nanomita, he whānuitia ngā tono mō te paura karāpiti nanomita nā te iti o te rahi o te matūriki, te nui o te waro, me te pai o te hinu whakahinuhinu, te kawe hiko teitei, te ātete pāmahana teitei, me ētahi atu. Ko te whānuitanga o te tono o te paura karāpiti nanomita kei roto i ngā mara whakaputa ahumahi pēnei i te hinu whakahinuhinu me te kawe hiko.
He pai ngā matūriki karāpeti nanomita, ā, he pai te matotoru o ngā matūriki. Ka hangaia he paparanga tiaki pakari, ā, tata kore e mau, e herea ana ki te mata whakarewa. Ka taea hoki te whakaranu ki ngā rauemi kore-arataki pēnei i ngā kapia me ngā hua rapa me ngā hua kirihou hei hanga rauemi hiato arataki. Ka taea hoki te hanga karāpeti nanomita hei paninga arataki. Ko ngā paninga arataki hiato i whiwhihia mā te tāpiri i ngā whakakī arataki he āhuatanga hiko pakari, pumau hoki. He painga ōna ko te arataki wera pai, te arataki hiko pai rawa atu, me te ātete tino teitei ki te waikura. He rite te rahi o te matūriki karāpeti nanomita, he parakore teitei, me te kaha o te mata. He pai hoki te arataki hiko me te mahi whakahinuhinu, tae atu ki te ātete pāmahana teitei, te ātete kakahu, me te pumau matū o te paura karāpeti. Nō reira, he whānui rawa te whānuitanga o te whakamahinga o te paura karāpeti nanomita i roto i te ahumahi.
He whānuitia hoki te whakamahinga o te paura nano-graphite hei whakatika i ngā pākahiko rokiroki. Mā te tāpiri i te nano-graphite ki ngā pākahiko kua whakamahia ka taea te whakanui ake i tō rātou kaha rokiroki ki te neke atu i te 90% o te taketake, ā, ka roa ake te roa o tō rātou oranga mahi mō te iti rawa i te kotahi tau. Ka tino penapenahia te utu whakamahi o ngā pākahiko rokiroki, ā, he mea nui anō hoki ki te whakahaere i te parahanga pākahiko me te tiaki taiao.
He whānuitia ngā whakamahinga o te paura karāpiti i roto i te ahumahi. Ka taea te whakamahi i roto i ngā momo mara whakaputa ahumahi. He rerekē ngā utu mō ngā whakamahinga rerekē o te paura karāpiti. He pai ngā pānga whakamahinga o te paura karāpiti i roto i ngā mara pēnei i te hinu whakahinuhinu ahumahi, te whakarewa, te kawe hiko, me ngā rauemi ātete ahi. Ko ngā āhuatanga pēnei i te whakamahinga, te rahi o te matūriki, me te momo paura karāpiti ka pā ki tōna utu.
He rerekē ngā whakamahinga o te paura karāpiti, nō reira he maha ngā momo paura karāpiti. He rerekē ngā utu o ngā momo paura karāpiti. Ka taea te tukatuka i te karāpiti maramara hei paura karāpiti o ngā whakatakotoranga me ngā rahi matūriki rerekē mā roto i ngā taputapu kuru me ngā tikanga whakaputa rerekē. Hei kaihanga paura karāpiti, ko ngā whakatakotoranga o te paura karāpiti kua hangaia mai i te 80 mata ki te 15000 mata. He rerekē ngā whakatakotoranga me ngā rahi matūriki o te paura karāpiti, me tōna utu anō hoki. I muri i te tukatuka mā roto i ngā tikanga whakaputa, he pai te hinu whakahinuhinu o te paura karāpiti, te ātete ki te pāmahana teitei, te kawe hiko, te ātete ki te waikura, me ētahi atu. Ka taea hoki e te paura karāpiti te whai wāhi ki ngā momo ahumahi whakaputa rerekē.
Ko ngā momo paura karāpiti ko: te paura karāpiti marara, te paura karāpiti tino pai, te paura karāpiti nano, te karāpiti colloidal, te karāpiti whānui, te karāpiti whakawhanui, te karāpiti paura moroiti, me ētahi atu. Ka tukatukahia ēnei paura karāpiti katoa mā roto i ngā tikanga whakaputa rerekē, ā, he rerekē hoki ā rātou whakamahinga. Ka whakamahia te paura karāpiti i roto i ngā mara whakaputa hinu whakahinuhinu, hinu whakahinuhinu totoka, oko karāpiti, pereki ātete, irahiko karāpiti, paraihe, irahiko kore-pāhiko, me ētahi atu. He tino pai ngā whakamahinga o ēnei katoa.
