Ko te kōka whakapūkara he momo pūwhakapūkara me te kōka hinuhinu o ngā whakatakotoranga rerekē.
Ko ngā whakatakotoranga matua o ngā hua karāhe ko ￠150-￠1578 me ētahi atu tauira. He mea nui tēnei mō ngā umanga rino me te maitai, ngā umanga silicon polysilicon ahumahi, ngā umanga emery, te umanga rauemi rererangi me ētahi atu hua.
1: Kōka hinu
He hua hinu totoka pango, hina pouri rānei te kōka hinu, he kanapa whakarewa, he pūwero hoki. He rauemi waro kirikiri, poutū, rite rānei ki te ngira, he mea hanga mai i ngā tioata karāpeti moroiti.
Kei roto i te kōka hinu ngā hauwaiwaro, 90-97% te waro, 1.5-8% te hauwai, te hauota, te māota, te whanariki, me ngā matū konganuku taumaha.
Ko te kōka hinu te hua o te whakapūkara o te hinu mata i roto i te wāhanga kōka whakaroa hei whakaputa hinu māmā i te pāmahana tiketike.
Ko te nui o te hinu mata e puta mai ana i te kōka hinu he 25-30% te nui atu i te hinu mata.
Ko tōna uara kaha iti he 1.5-2 ngā wā o te waro, kāore e neke ake i te 0.5% te nui o te pungarehu, he 11% te nui o te haukū, ā, he tata tōna kounga ki te anthracite.
2: Paerewa kounga o te kōka hinuhinu Ko te kōka hinuhinu whakaroa e pā ana ki te kōka i hangaia e te wae kōka whakaroa, e mōhiotia ana ko te kōka noa, kāore he paerewa ## e rite ana.
I tēnei wā, ko te nuinga o ngā umanga whakaputa ā-rohe e whakaputa ana i ngā hua e ai ki te paerewa ahumahi SH0527-92 i titoa e te kamupene o mua o China Petrochemical Corporation.
Ko te nuinga o te whakarōpūtanga o te paerewa e ai ki te ihirangi whanariki o te hinu kōke.
He pai te kōke Nama 1 mō te hanga i te hiko karāhe mana noa i roto i te umanga hanga maitai, ā, ka whakamahia hoki hei waro mō te whakamahine konumohe.
E whakamahia ana te kōka Nama 2 mō te hanga whakapiri hiko me te hiko karāpeti i roto i te pūtau hiko (ouma) i roto i te umanga whakarewa konumohe.
E whakamahia ana te kōka Nama 3 i roto i te hanga i te silicon carbide (rauemi huri) me te calcium carbide (calcium carbide), me ētahi atu hua waro, tae atu ki te hanga poraka anode mō te whakarewa konumohe me te hanga pereki arai waro, te raro oumu rānei i roto i te oumu pupuhi.
3: ngā whakamahinga matua o te kōka hinu
Ko ngā whakamahinga matua o te petroleum coke ko te anode kua tunua me te whakapiri anode mō te konumohe hikohiko, te hanga waro o te kaihoko whakapūkara, te hiko graphite, te whakarewa i te silicon ahumahi me te wahie, me ētahi atu.
E ai ki te hanganga me te āhua o te kōka hinu, ka taea te wehewehe i ngā hua kōka hinu ki te kōka ngira, te kōka hautai, te kōka pere me te kōka paura:
(1) Ko te kōke āhua-ngira, he rite te hanganga ki te ngira me te kakano muka, e whakamahia whānuitia ana hei hiko karāti mana-teitei me te hiko karāti mana-tino-teitei i roto i te hanga maitai.
Nā te mea he tino kaha ngā whakaritenga kounga mō te ihirangi whanariki, te ihirangi pungarehu, te ihirangi matū me te mātotoru pono o te ngira Coke, he whakaritenga motuhake kei runga i te hangarau whakaputa me ngā rauemi mata o te ngira Coke.
(2) Ko te kōka hautai, he nui te tauhohenga matū me te iti o te poke, e whakamahia ana i roto i te umanga whakarewa konumohe me te umanga waro.
(3) Koka pere, koka porowhita rānei: he porowhita te āhua, ā, he 0.6-30mm te whānui. I te nuinga o te wā ka hangaia mai i ngā toenga nui-whāwhā me te nui-āparapara, ā, ka taea anake te whakamahi mō te whakaputa hiko, te sima me ētahi atu wahie ahumahi.
(4) Koka paura: ka hangaia mā te tukanga koka wai me ngā matūriki angiangi (diameter: 0.1-0.4mm), he nui te ihirangi mimiti me te tauwehenga whānui wera nui, nō reira kāore e taea te whakamahi tika i roto i te whakarite hiko me te umanga waro.
4: Kōka hinu kua whakapūkaratia
Ina tutuki i te hiko graphite mō te hanga maitai, i te whakapiri anode rānei (hiko rewa) mō te konumohe me te konupora, kia hanga ai te coke hinu (coke) i ngā whakaritenga, me whakapūkara te coke.
Ko te pāmahana whakawera i te nuinga o te wā he 1300℃, ko te whāinga he whakakore i te mimiti o te naphthol coke i ngā wāhi katoa e taea ana.
Mā tēnei ara, ka taea te whakaiti i te nui o te hauwai i roto i ngā hua o te petroleum coke, ka taea te whakapai ake i te taumata whakakāwhata o te petroleum coke, ka taea te whakapai ake i te kaha pāmahana teitei me te ātete wera o te electrode karāhe, ā, ka taea hoki te whakapai ake i te kawe hiko o te electrode karāhe.
Ko te whakapūkara te nuinga e whakamahia ana mō te whakaputa i ngā hiko karāpeti, ngā hua whakapiri waro, te onepu taimana, te ahumahi whākawa kai-kounga, te ahumahi whakarewa me te konupūmā kāpōti, ā, i roto i ēnei hiko karāpeti e whakamahia whānuitia ana.
Ka taea te whakamahi tika i te Coke, kāore he hanga, hei konupūmā carbide, hei silicon carbide me te boron carbide hei rauemi huri.
Ka taea hoki te whakamahi tika hei Coke mō te oumu whakarewa i roto i te umanga whakarewa, hei pereki waro rānei e whakapuru ana i te oumu whakarewa, ā, ka taea hoki te whakamahi mō te tukatuka Coke kiato, me ētahi atu.
