Ko ngā para nui o te ahumahi o Haina he para, he pungarehu rere, he konukōre waro, he para whakarewa, he para waro me te gypsum whakakorenga whanariki. Kua nui haere te aro ki te whakarite rauemi hanga mai i ngā para totoka. Kua whakapai ake ngā kairangahau i te tere whakamahinga whānui o ngā para totoka i roto i te ahumahi rauemi hanga mā te whakapai ake me te rangahau me te whakawhanake i ngā taputapu me te hangarau. I taua wā anō, kua whakaputa ngā whenua maha i ngā ture me ngā ture tautoko hei whakaoho i te hihiri o ngā umanga ki te whakamahi i ngā para totoka, kia pai ake ai te pānga o ngā para totoka ahumahi ki te taiao ki tētahi taumata. Hei kaihanga o te mira huri para rino, ko tā mātoumira roera poutū para rino kua whānuitia te whakamahinga i roto i te kaupapa whakamahinga whānui o ngā rauemi hangahanga mō te huri onepu me te para rino. Ka whakauruhia e HCMilling (Guilin Hongcheng) te hangarau mō te whakarite rauemi hangahanga mai i ngā para rino.

1. Te kirīni sima kua whakapūkaratia

He nui te rino i roto i te paru rino, ka taea te whakakapi i te paura rino hei rauemi mata mō te hanga sima clinker. Mā te tahu i te sima clinker me te kōhatu papa, te onepu kuata me ngā paru rino hei rauemi mata ka taea te whakaiti i te pāmahana whakapūkara me te utu o te sima, engari he iti te nui o te whakaranu, ā, mā te nui o te whakaranu ka tino whakaiti i te kaha o te sima. I tēnei wā, ko te nui o ngā paru rino e whakamahia ana mō te whakapūkara i te sima clinker he tata ki te 15% noa iho. He mea nui kia tere te whakawhanake i ngā taputapu hou me ngā hangarau hou hei whakapai ake i te nui o ngā paru rino me te whakarite i te kounga o ngā hua sima.

2. Te konupūmā raima

Ko te pakeketanga nui o ngā paru rino i ahu mai i te wāhanga quartz o roto, ko tōna rahi matūriki he tata ki ētahi onepū awa tūturu me te onepū hanga, ā, ka taea te whakaranu ki te raima hei konganuku. Ka taea te whakarite i te raima me te kaha 28d o te 40MPa mā te whakamahi i ngā paru rino he iti iho i te 1mm te rahi matūriki hei whakakapi i te onepū awa tūturu hei konganuku pai. I runga i te arotautanga o te whakarōpūtanga o te konganuku, ko te whakamahinga whakakotahi o ngā paru rino me te onepū hanga-mīhini hei konganuku kāore e taea anake te whakatutuki i ngā whakaritenga o te raima mō ngā rauemi, engari he pai ake te pumau i ērā o ngā paru rino me te onepū awa tūturu, he pai ake te whakahaere i te kounga o te raima. Mō te tukanga whakapai ake o nāianei, hei whakapai ake i te tere whakaora whakarewa, kei te pai haere te kiko o ngā matūriki paru rino, he uaua ki te whakatutuki i te paerewa o te konganuku matotoru me te whakamahi ki te raima noa.

3. Ranunga kohuke raima

Ko ngā tāpiringa kohuke he mea hanga i ngā rauemi siliceous, calcareous me te konumohe kore-āhua, he mea nui ēnei ki te whakapai ake i te kiato, te ātete-wai me te pakari o te raima. Ka taea e rātou te whakaiti i te whakamahinga sima me te whakaiti i te wera o te wai i te wā kotahi. Nō reira, he mea nui kia kitea he tāpiringa kohuke hou mō te whanaketanga pumau o te umanga sima. Ko te wāhanga kohuke matua i roto i ngā toenga rino he quartz, he iti noa te mahi pozzolanic i roto i te āhua tūturu. Ko te whakapai ake i te "mahi pozzolanic" o ngā toenga rino kua noho hei kaupapa matua a ngā kairangahau o nāianei. Hei tētahi o ngā tikanga e whakamahia whānuitia ana mō te whakahohe i ngā toenga rino, ka taea e te huri ā-ringa te whakaiti i te kaha whakahohe o ngā toenga rino me te whakaputa i ngā hapa whatunga me te whakarerekētanga kirihou. E whakaatu ana te rangahau ka taea e te huri ā-ringa te whakaoho i te mahi pozzolanic o ngā wāhanga kohuke noa i roto i ngā toenga rino. I te mea ka heke te rahi o te matūriki o ngā kohuke i hurihia ā-ringa, ka taea e te quartz te tauhohe ki te Ca (OH) 2 i roto i te paru sima hei whakaputa i te konupūmā silicate wai kore-āhua me te tioata ettringite me ētahi atu hua wai. E whakaatu ana te rangahau, ina neke atu i te 40 meneti te roa o te huri ā-ringa, ka tino heke te koki koi o ngā paru rino, ka nui ake ngā matūriki iti e kitea ana, ā, ka āta whakapai ake te ōritetanga. I roto i te pūnaha konupūmā waikura paru rino anhydrite, ka taea te whakaranu i te paru rino siliceous o te huri ā-ringa ki te 30% hei whakarite i te sima 32.5. I raro i te āhua o te ōwehenga here wai iti, ka taea e te paura paru rino pai te whakatairanga i te makuku wawe o te whakapiri sima hiato, te hanga i te hanganga pore o te moata kia kikī ake, me te whakapai ake i te kaha wawe. Ko te whakanui ake i te horahanga mata motuhake o ngā paru rino kāore he pānga mārama ki te whakapai ake i tana taupū ngohe; Ko te huringa o te pāmahana whakaora ka taea te whakanui ake i te taupū ngohe i te wā tōmua (7d), engari he iti noa te pānga ki te taupū ngohe i te wā tōmuri (28d). Mō te pūnaha hiato paru paru rino, ka taea te whakapai ake i te taupū ngohe mā te whakapai ake i te tikanga huri, kia pai ake ai te roa o te raima. Mā te whakamahinga tika o te kaihoko whakaiti wai ka taea te whakanui ake i te ihirangi o ngā paru rino i roto i te raima noa mai i te 30% ki te 40%. Mā te huri i ngā paru rino ka taea te whakapai ake i te whai huatanga o te huri mā roto i tōna ake pānga, ā, ka whakaoho i te mahi pozzolanic o ngā paru rino. Mā te arotau i te ōwehenga o ngā paru rino, te para, te kirīni me ngā rauemi sima gypsum, ka taea te whakarite i te raima tino-teitei me te mahi e tutuki ana i te paerewa ā-motu.
