He hua taha te paura kōka i puta mai i te tukanga kōka. Nā te iti rawa o ōna matūriki, ina kohia ki roto i te oumu pupuhi, kāore e maeneene te rere o te hau, ka pā ki te rere noa o te pou rauemi i roto i te oumu pupuhi, ā, kāore e taea te whakatutuki i ngā whakaritenga o te kōka whakarewa. Nā te mea he nui te ihirangi waro o te paura kōka, he āputaputa ā-roto kua whanake, me te kaha, kua whakahaerehia e ngā kairangahau pūtaiao Hainamana he rangahau whānui me te hohonu mō te whakamahi i te paura kōka i ngā tau tata nei. Ko HCMilling (Guilin Hongcheng) he kaihanga okōka whakarewamira huri. Koinei te kupu whakataki mō te whakamahinga o te mira huri kōka whakarewa:

1. Waro whakahohe mai i te paura huri kōka whakarewa: He rauemi waro te waro whakahohe me te hanganga moroiti kua whanaketia me te kaha mimiti kaha. He whānuitia te whakamahinga i roto i ngā momo mara pēnei i te ahumahi matū, te tukatuka kai, te tiaki hōia me te ahumahi tiaki taiao. Ko te mahi a te waro whakahohe e pā ana ki tōna horahanga mata motuhake, te rahinga moroiti, te tohatoha rahi o ngā pore me te hanganga matū. I tēnei wā, ko ngā rauemi mata matua mō te whakarite ahumahi o te waro whakahohe i tōku whenua ko te rakau me te waro. I ngā tau tata nei, nā te pikinga o te korenga o te pūngao me te aro nui o te whenua ki te tiaki taiao, kei te rapu tonu te iwi i ngā rauemi mata rerekē mō te whakarite i te waro whakahohe. Ko te paura kōka he hua taha o te ahumahi kōka. He nui te ihirangi waro pumau, he iti te ihirangi pupuhi me te pungarehu, he kaha teitei, ā, he ngāwari te wātea o ngā rauemi mata. He rauemi pai mō te whakarite i te waro whakahohe. I tēnei wā, ko te waro whakahohe ka hangaia mā te maimoatanga i te paura kōka mā te whakahohenga ā-tinana me te whakahohenga matū. Ko te tikanga whakahohenga ā-tinana me whakapūmau i ngā rauemi mata i mua i te whakahohenga, kātahi ka whakahohehia i te 600 ki te 1200°C. Kei roto i te kaiwhakaoho ngā hau whakahāora pērā i te CO2 me te mamaoa wai, ā, ko ngā ngota waro i roto i te rauemi whakahāora waro o te hau e whakamahia ana hei haere mā roto. Ka hangaia te waro whakahohe me ngā pūwero kua whanake pai mā te whakatuwhera, te whakawhanui me te waihanga i ngā āputa hou. Ko te whakahohenga matū e pā ana ki te whakaranu i ngā rauemi mata me ngā kaiwhakaoho (ngā waikura konganuku kawakore me ngā waikura kawakore, ngā tote kore-waro me ētahi waikawa) i roto i tētahi ōwehenga, ka rumakina mō tētahi wā, kātahi ka whakaoti i ngā mahi whakahāora me te whakahohe i roto i te kotahi taahiraa.

2. Te maimoatanga wai para matū koiora mā te paura huri kōka whakarewa: he tikanga noa te tikanga mimiti hei rongoā i te wai para kōka. Nā te whanaketanga o ngā āputa o roto o te paura kōka me te pai o te mahi mimiti, kua rangahau ētahi kairangahau i Haina mō te maimoatanga paura kōka i te wai para kōka. Ka whakamahia e Zhang Jinyong te paura kōka i whakahohehia e te mamaoa hei mimiti i te wai para matū koiora mai i te tipu kōka. I muri i te mimiti, ka whakaitihia te hiahia hāora matū (COD) o te wai para mai i te 233mg/L ki te 50mg/L, ka eke ki te paerewa tukunga tuatahi o te motu. I whakamahia e Liu Xian me ētahi atu te paura kōka mō te maimoatanga mimiti tuarua o te wai para kōka, ā, i akohia ngā tikanga tukanga tika mō te mimiti paura kōka i te wai para kōka mā te whakamātautau tonu me te hihiri. E whakaatu ana ngā hua rangahau ka taea te whakaiti i te COD o te wai para matū matū koiora i muri i te maimoatanga paura kōka matatau ki raro iho i te 100mg/L, ā, ka taea e te tere tango chromaticity te eke ki te neke atu i te 60%, e tutuki ai ngā whakaritenga kounga wai o ngā umanga kōka.

3. Te hanga o te paura huri kōka whakarewa me ngā tāpiringa: kāore he piri o te paura kōka tonu, ā, he maha ngā wā ka whakamahia mā te tāpiri i tētahi here ki roto hei pēhi me te hanga. He maha ngā momo tāpiringa paura kōka, ā, kāore te kounga o te kōka i hangaia he ōrite. I whakamahia e Liu Baoshan te matū whakaranu o te humate, te toenga para māngaro, te paru waro, te houra tunutunu me te bentonite hei herenga hei ako i te nui o ngā tāpiringa, ngā āhuatanga hanga o te paura kōka, te āhua me te rahi o te matūriki o te pōro hanga, me te pāmahana whakamaroke, ā, i whakamatautauria, i tahuna hoki ngā pōro kua whakaritea, ā, i whakaatuhia e ngā hua he kaha me te pumau o te wera o ngā pōro paura kōka, ā, ka taea te whakamahi hei whakaputa hau hangai. I whakamahia e Zhang Liqi te paura kōka me te toenga tā i hangaia e te kaihanga hau hei whakaranu me te hanga kia rite ki tētahi ōwehenga, kātahi ka waikurahia, ka warohia hei hanga i te kōka hei whakapūhautanga. Kua eke ngā āhuatanga o te kōka ki te paerewa o te kōka whakapūhautanga. Ka whakaratohia he pūtake ariā mō te hanga ahumahi.

4. Te paura huri kōka whakarewa hei whakaputa kōka whakarewa: ko te paura kōka te tikanga e whakamahia ana hei whakangawari i roto i te tukanga kōka. Mā te tāpiri i te paura kōka tika ki te tukanga kōka ka taea te whakapai ake i te kounga o te kōka. Nā te piki haere o te korenga o ngā rauemi waro kōka i Haina, kia whānui ake ai ngā rauemi waro kōka me te whakaiti i te utu o te whakaranu waro, he maha ngā umanga kōka kua ngana ki te whakamahi i te paura kōka hei wāhanga whakaranu waro mō te kōka hei whakapai ake i ngā painga ōhanga o te paura kōka. He maha ngā umanga i Haina kua rangahau i te rahi o te matūriki me te ōwehenga o te paura kōka. I whakahaerehia e Yang Mingping he whakamātautau whakaputa ahumahi i runga i te whakamātautau oumu kōka iti. E whakaatu ana ngā hua i raro i ngā tikanga tukanga kōka uta-runga tikanga, ka taea te tāpiri i te 3% ki te 5% o te paura kōka hei whakakapi i te waro kikokore mō te kōka. I piki ake te tohu poraka, ā, i piki ake te tere tauwhitinga mā te 3%. Nā roto i te rangahau, i kitea e Wang Dali me ētahi atu kāore he pānga mārama o te kōka me te paura kōka ki te whakaata nui o te vitrinite o te waro whakaranu. Heoi, mā te ine i te iti rawa, i kitea ko ngā matūriki paura kōka nui atu i te 0.2mm he motuhake i roto i te kōka, ā, he uaua ki te whakauru ki ētahi atu wāhanga, ā, kāore i rerekē te āhua; i te mea ko te paura kōka iti iho i te 0.2mm he ngāwari te takai ki te kōroiti, he pai mō te hanganga kōka. Ko te ōwehenga tino pai o te paura kōka he 1.0%-1.7%, ko te awhe rahi matūriki tino pai he 98%-100% iti iho i te 3mm, 78%-80% iti iho i te 1mm, me te 40%-50% iti iho i te 0.2mm.

Kāore e taea te wehewehe i te huri kōka whakarewa i te mira huri kōka whakarewa. Hei kaihanga mira huri kōka whakarewa, ka hangaia e HCMilling (Guilin Hongcheng)kōka whakarewa Raymondmira, kōka whakarewa tino paimira, kōka whakarewa poutūroeramirame ētahi atu taputapu. Ka taea e ia te whakaputa paura kōka whakarewa 80-2500 mata me te whakarato tautoko hangarau mō te tono o te paura huri kōka whakarewa.
