I tēnei wā, kei te piki haere te maha o ngā para karāhe e hangaia ana i ngā mara whakaputa me ngā mara noho, ā, kei te noho hei tūponotanga tūmatanui. Nā te pumau o ngā matū o ngā para karāhe, kāore e pirau, e wera, e rewa, e memeha noa rānei i roto i te oneone. He kaihanga a HCMilling (Guilin Hongcheng) okarāhemira huri taputapu. Koinei te kupu whakataki ki ngā tikanga hangarua karāhe.

  karāhemira huri 

Ko te karāhe e whakamahia ana e tātou i nāianei he mea hanga mai i te onepū kuata, te pungarehu houra, te feldspar me te kōhatu i te pāmahana teitei. He rauemi totoka kore-āhua i whiwhihia mā te whakanui ake i te matotoru o te rewa i te wā e whakamatao ana. He pakarukaru, he mārama hoki. Kei reira te karāhe kuata, te karāhe silicate, te karāhe houra raima, te karāhe fluoride, me ētahi atu. Ko te tikanga e pā ana ki te karāhe silicate, he mea hanga mai i te onepū kuata, te pungarehu houra, te feldspar me te kōhatu mā te whakaranu, te rewa pāmahana teitei, te whakakotahi, te tukatuka me te whakamahana. He whānuitia te whakamahinga i roto i te hanga, te whakamahinga o ia rā, te hauora, te matū, te hiko, ngā taputapu, te miihini karihi me ētahi atu mara. I nāianei, ko te hangarua karāhe te nuinga o te tukatuka hei paura karāhe mā te huri, e whakamahia ana i ngā huarahi e whai ake nei:

1. Ka tukatukahia te paura karāhe hei rauemi turanga sima: ko te wāhanga matua o te karāhe he silica hohe, nō reira ka taea e ia te whai mahi pozzolanic i muri i te hurihanga hei paura, ā, ka taea te whakamahi hei ranunga hei whakarite i te raima. Ehara i te mea ka taea anake te whakaoti i te raruraru o te whakakorenga o ngā para karāhe, engari ka whakatairanga hoki i te whanaketanga o ngā rauemi hanga whare matomato. (1) Ka taea te whakarite i ngā rauemi sima tino kaha me te kaha pēhi neke atu i te 100MPa mā te whakaranu i te paura karāhe. Ina iti iho i te 20% te ihirangi paura karāhe, ka piki ake te kaha pēhi o te tauira me te pikinga o te ihirangi paura karāhe; Ka whai wāhi hoki te pikinga o te pāmahana whakamaroke ki te tauhohenga pozzolanic o te paura karāhe. Nō reira, ka taea hoki e ia te whakatairanga i te tipu o te kaha. (2) He kaha te mahi pozzolanic o te paura karāhe me te pānga whakakī i roto i te pūnaha whakakī. Ehara i te mea ka taea anake te whakakī i ngā pūwero i roto i te hanganga paru, engari ka tauhohe hoki ki te whakaputa i te CSH gel, te whakapai ake i te hanganga moroiti o te rauemi me te whakarei ake i te kaha o te rauemi.

2. Te tukatuka paura karāhe hei rauemi mata mō te karāhe: ka kohia, ka whakarōpūtia, ka tukatukahia hoki ngā para karāhe hei rauemi mata mō te hanga karāhe, koinei te huarahi matua ki te hangarua i ngā para karāhe. Ka taea te whakamahi i ngā para karāhe mō te hanga hua karāhe he iti ngā whakaritenga mō te hanganga matū, te tae me ngā poke, pērā i te karāhe pounamu tae, te ārai karāhe, te pereki karāhe kōhao, te karāhe awaawa, te karāhe whakairo, te pōro karāhe tae me ētahi atu hua karāhe. Ko te nui o ngā para karāhe e konatunatua ana ki ēnei hua he nui ake i te 30wt%, ā, ko te nui o ngā para karāhe e konatunatua ana ki ngā hua pounamu me te ipu kakariki ka eke ki runga ake i te 80wt%. Mena ka hangaruahia te 50wt% o ngā para karāhe ki Haina, ka taea te penapena i te 3.6 miriona tana o ngā rauemi mata hiraka, te 0.6 miriona tana o te pungarehu houra me te 1 miriona tana o te waro paerewa i ia tau.

3. Te tukatuka paura karāhe hei rauemi paninga: Ka whakamahia e te Kamupene Poari muka rakau Changsheng o Hapani te karāhe para me ngā potae para hei pakaru hei paura pai, ka konatunatua ki te paninga i roto i tētahi ōwehenga, ka taea te whakakapi i te silica me ētahi atu rauemi i roto i te paninga. Ka whakamahia hei wawahi i ngā pounamu karāhe kau hangarua, hei huri i ngā taha me ngā kokonga, hei tukatuka hei taha haumaru, kia hanga ai he karāhe pakaru me te āhua tata rite ki ngā matūriki onepu tūturu, kātahi ka whakaranua ki te nui o te peita. Ā, ka hoatu he kakano me te tauira kāore i te peita o mua. Ka taea te hanga i tēnei momo peita hei peita motuka wairewa-wai. Ka taea e ngā mea e whakamahi ana i tēnei momo peita karāhe para whakauru te whakaputa whakaata horapa ina pā ki ngā rama motuka, ki te rā rānei, he pānga rua ki te ārai i ngā aituā me te whakapaipai.

4.Te huri karaihe mmāuiui e whakamahia ana hei tukatuka i ngā rauemi mata mō ngā uku karāhe: he mārō ngā uku karāhe, he kaha miihini teitei, he pumau matū pai, he pumau wera hoki. Heoi, he nui te utu whakaputa o ngā rauemi mata tuku iho e whakamahia ana mō ngā uku karāhe. I ngā whenua ke, kua angitu te whakaputa uku karāhe mā te whakamahi i te karāhe para mai i te tukanga pōturi me te pungarehu rere mai i ngā tipu hiko hei utu mō ngā uku karāhe tuku iho. Ka hangaia tēnei uku karāhe mā te huarahi hangarau o te whakakotahi i te rewa me te whakahinuhinu: te whakaranu i te pungarehu rere me te karāhe para, te rewa i te 1400 ℃, te hanga karāhe kore āhua, te tinei wai, te huri, me te whakahinuhinu i te 810~850 ℃, ka taea te hanga hei uku karāhe me ngā āhuatanga miihini pai, e tika ana mō te mara hanga. Kua angitu ngā kairangahau pūtaiao o Te Whare Wānanga o Tsinghua me Te Whare Wānanga Hangarau o Wuhan i Haina ki te hangarau matua o te whakamahi i te pungarehu rere, te gangue waro, ngā momo paru ahumahi, te para whakarewa me te paru awa kōwhai hei rauemi matua hei whakaputa panera whakapaipai uku karāhe.

5. Mā te mira huri karāhe ka hangaia te mosaic karāhe: hurihia kia mātotoru te para karāhe kia paura karāhe, kātahi ka tāpirihia he nui o te piri, te tae, te tango tae rānei, ka whakaranua kia ōrite ki te mīhini whakaranu. Ka pēhia te puranga ki roto i te tinana matomato mā te tikanga pēhi maroke, ā, ka tukuna te tinana matomato maroke ki te oumu hurihuri, oumu pana, oumu kauhanga rānei me te pāmahana tahu o te 800~900 ℃ hei whakahinuhinu, ā, ko te tikanga ka noho ki te rohe pāmahana whakahinuhinu mō te 15~25 meneti. Ko ngā hua kua whakamataohia i waho o te oumu me tirotirohia, me tīpako, me whariki, me whakamaroke, me tirotirohia, me tākai, me rongoa, me tuku rānei, ā, ko ngā hua kāore i te tika me hangarua.

6. Te tukatuka me te whakaputa rauemi whakamahana me te whakamahana oro mā te mīhini huri karāhe: he momo rauemi karāhe te karāhe pahuka, he iti te matotoru, he kaha teitei, ā, he iti ngā pore. Ko te wāhanga hau e 80% – 95% o te katoa o ngā hua. Ki te whakatauritea ki ētahi atu rauemi whakamahana me te whakamahana oro kore-ora, he pai ngā painga o te whakamahana me te mahi whakamahana oro, te kore-waikura, te ātete ki te waikura, te ātete ki te hukapapa, te kore-tahu, te ngāwari ki te hono me te tukatuka. "Ko tana tukanga whakaputa he kuru i te karāhe para, tāpirihia te konupūmā kāponāte, te paura waro - he momo kaihoko pahuka me te whakatere pahuka, whakaranua kia ōrite, maka ki roto i te pokepokea ai, ka maka ki roto i te oumu hei whakamahana. I raro i te pāmahana whakangawari, tāpirihia te kaihoko pahuka hei hanga mirumiru ki runga i te karāhe, kātahi ka hanga karāhe pahuka. I muri i te tangohanga o te karāhe i roto i te oumu, ka tihorea, ka whakamahanahia, ka tapatapahia ki te rahi paerewa.

Hei momo rauemi, ko te karāhe para te huarahi pai ki te hangarua i te nui o te karāhe mā te whakamahi i roto i ngā rauemi hanga. Kua whakaatuhia e ngā hua rangahau o nāianei he mea taea te whakamahi i te karāhe para hei ranunga kohuke mō te raima, engari kāore anō kia tutuki te tono ahumahi nā te hangarau taputapu me ētahi atu take. Ko tekarāhemira huriKo te taputapu matua e whakaratohia ana e HCMilling (Guilin Hongcheng) te hanga i te nui o te karāhe e hiahiatia ana mō te hangarua karāhe. Ka whakamahia mō te huri karāhe, ā, ka taea te whakatutuki i ngā tekau tāne o te putanga i ia hāora mīhini, ā, ka taea te whakaputa i te paura karāhe 80-600 mata.
