Whakaahuatanga Poto:
E mōhiotia ana a Haina mō āna rahui tārai nui, me ngā putunga nui e horapa ana puta noa i ngā rohe pēnei i a Liaoning, Shandong, me Guangxi. He rerekē ngā tikanga hanganga o ēnei putunga e whakaata ana i te hītori matawhenua matatini o te whenua.
Ko Liaoning, inā koa te rohe o Dashiqiao, tētahi o ngā pūtake hanga talc nui o Haina. I konei, i hangaia ngā putunga talc mā te hurihanga o te dolomite me te magnesite i raro i ngā āhuatanga pāmahana me te pēhanga teitei i te wā Proterozoic. Nā ngā nekehanga tectonic roa me ngā mahi hydrothermal i tēnei rohe i whakatairanga i te whakakōkī anō o ngā kohuke, ā, ka āta puta ake he talc kounga teitei me te kakano maeneene me te hanganga lamellar pai. He rite tēnei tukanga whenua ki te hurihanga o ētahi hanganga toka tawhito i raro i ngā āhuatanga tino kino hei hanga i ngā putunga kohuke ahurei.
I Shandong, ko te tāke i ngā wāhi pērā i a Yishui me Junan i ahu mai i te whakarerekētanga o ngā toka ultramafic. I te wā i taunekeneke ai ēnei toka me ngā wai hydrothermal he nui te silica, ka puta he raupapa o ngā tauhohenga matū, ka hua ake te hanganga o te tāke me te mā me te hinu pai, ā, he tino pai mō ngā ahumahi pērā i te uku me te whakapaipai.
Ko ngā putunga talc o Guangxi, i roto i ngā rohe pēnei i a Hezhou, i hangaia i roto i tētahi taiao whenua rerekē. He maha ngā wā e hono ana ki ngā tukanga whakapūtātanga o te oneone, arā, ko te whakapūtātanga o ngā toka whakapūtātanga kei roto ngā rauemi whai konupora, ā, ka hua ake te whakanikoniko o te talc.
Ka whakamahia e ngā kaimaina Haina he huinga o ngā tikanga keri tuwhera me ngā tikanga keri raro whenua, i runga i te hohonu me te tauine o ngā putunga. Mō ngā putunga papaku, ko te keri tuwhera te mea e pai ake ana mō tōna whai huatanga me te utu iti, ko ngā tikanga keri raro whenua ia e whakamahia ana mō ngā rauemi hohonu ake. Whai muri i te tangohanga, ka haere te talc Hainamana i roto i tētahi mekameka tukatuka tino tupato, tae atu ki te whakakakahu i te konganuku, te huri pai, me te whakarerekētanga mata. Ka wehea te talc mai i ngā kohuke gangue e pā ana ki te whakakakahu konganuku, ā, ka tukatukahia te talc ki ngā taumata pai rerekē e ai ki ngā tono ahumahi rerekē. Ka mahia te whakarerekētanga mata hei whakapai ake i te hototahitanga o te talc me ētahi atu rauemi, inā koa i roto i ngā tono teitei pēnei i te kirihou me te rapa. Kua hangaia ēnei mahi tukatuka hei whakanui ake i te uara whakamahinga o te talc, kia tutuki ai ngā whakaritenga rerekē o ngā mākete o te whare me te ao, pērā i te whakarei ake o ngā tikanga tukatuka i te whakamahinga o ētahi atu kohuke. Ko ngā rauemi talc whai rawa o Haina, me ō rātou takenga whenua ahurei me ngā tikanga tukatuka matatau, he mahi nui tā rātou i roto i te umanga talc o te ao.
Ko te paura talc, he kohuke konupora silicate tūturu, kua noho hei rauemi tūāpapa mō te hanga ahumahi nā tōna huinga ahurei o ngā āhuatanga ā-tinana me te matū. Kua hangaia te paura talc kounga ahumahi a tā mātou kamupene hei whakatutuki i ngā hiahia kanorau o ngā ahumahi kirihou, rapa, paninga, me te uku—e whā ngā rāngai e tino hira ana te pono, te ōritetanga, me te mahi ki te angitu o te mahi.
I roto i te hanga kirihou, ka mahi tā mātou paura talc kounga ahumahi hei whakakī maha-whakamahinga e whakarei ake ana i te kounga hua me te whai huatanga o te whakaputa. Ina whakauruhia ki roto i ngā kapia polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC) rānei, ka whakapai ake i te pumau o ngā āhuatanga mā te whakaiti i te whakahekenga i te wā e hangaia ana. He mea nui tēnei mō ngā wāhanga kirihou pēnei i ngā whakapaipai o roto o te motuka, ngā pouaka hononga hiko, me ngā anga taputapu o te whare, ina tika te rahi ka whakarite kia tika te taunga me te mahi. Ka whakanui ake hoki te hanganga lamellar o tā mātou paura talc i te pakari me te kore e whakararu i te ātete pānga, ka taea e ngā kaihanga te whakaiti i te matotoru o te rauemi me te pupuri tonu i te hanganga - ka tapahia ngā utu rauemi mata mā te 10–15%. Me ngā kōwhiringa rahi matūriki mai i te 200 ki te 1250 mata, ka aro mātou ki ngā tikanga tukatuka kirihou rerekē, mai i te werohanga werohanga ki te extrusion, te whakarite kia rite te horapa me te karo i ngā hapa pēnei i te whiri, te piri rānei.
Mō te hanga rapa, ka mahi tā mātou paura talc hei āwhina tukatuka me te kaiwhakakaha. Ka whakaiti i te matotoru o ngā matū rapa, ka maeneene ake te whakaranu me te whakaputanga, ā, ka pai ake te penapena pūngao. I roto i te rapa maori me te rapa hangai (pēnei i te rapa nitrile butadiene), ka whakarei ake i te ātete haehae me te ātete ki te pakū, ka roa ake te roa o te oranga o ngā hua rapa pēnei i ngā ngongo ahumahi, ngā whitiki kawe, me ngā gaskets. I kōrero tētahi kaihanga rapa i te Tonga-mā-rāwhiti o Āhia, ko te whakaurunga o tā mātou paura talc ki roto i ā rātou hanganga ngongo i whakanui ake i te roa o te hua mā te 25%, ka whakaiti i te auau whakakapinga mō ā rātou kiritaki. Hei tāpiri, ko te koretake o te matū o tā mātou paura talc ka whakarite kia hototahi ki ngā kaihoko whakamomona me ngā antioxidants, ka ārai i ngā tauhohenga kāore e hiahiatia ka taea te whakaiti i te mahi rapa i roto i te wā.
I roto i te umanga paninga, ka mahi tā mātou paura talc kounga ahumahi hei whakaroa me te whāriki. Ka whakapai ake i te mārama o ngā peita me ngā paninga, ka taea e ngā kaihanga te whakaiti i te nui o te titanium dioxide utu nui (TiO₂) me te pupuri tonu i te kapi—ka whakaiti i ngā utu hanga mā te 8–12%. Ka hangaia e ngā matūriki lamellar he ārai i roto i te kiriata paninga, ka whakarei ake i te ātete ki te wai, ngā matū, me te hihi UV. Nā tēnei ka pai tā mātou paura talc mō ngā paninga ahumahi e whakamahia ana i runga i ngā hanganga whakarewa, ngā mīhini, me ngā pakitara o waho, he mea nui te ātete ki te huarere mō te wā roa. I kitea e tētahi kaiwhakarato paninga Pākehā ko te whakamahi i tā mātou paura talc i roto i ā rātou hanganga enamel ahumahi ka whakanui ake i te roa o te mahi paninga mā te 30% i roto i ngā taiao kino o waho.
Ka whakawhirinaki ngā kaihanga uku ki tā mātou paura talc hei arotau i ngā tukanga whakaputa me te whakapai ake i te kounga o te hua. Ina tāpirihia ki ngā hanganga uku uku, ka whakaitihia te pāmahana tahunga mā te 50–100°C, ka whakaitihia te whakapaunga pūngao me te whakaiti i te ahotea wera i runga i ngā hua kua oti. Ka whakaitihia te tūponotanga o te pakaru me te whakapai ake i ngā reiti hua - he mea nui mō ngā taera uku, ngā taputapu horoi, me ngā ārai hiko. Ka whakarei ake hoki tā mātou paura talc i te mā me te kanapa o te uku, ka whakakorea te hiahia mō ngā kaihoko whakama atu, ā, ka hangaia he mutunga ataahua ake.
Kei roto i ia wāhanga o tā mātou tukanga whakaputa te mana whakahaere kounga. Ka tangohia e mātou te talc mata mai i ngā putunga parakore teitei i Liaoning me Shandong, Haina—he rohe rongonui mō te talc me te iti o te rino, te konupūmā, me te ihirangi konganuku taumaha. Ka kuruhia, ka hurihia, ka purea te konganuku mata mā te wehenga aukume me te pupuhi pahuka hei tango i ngā poke. Ka whakamatautauria ia puranga mā te whakamahi i ngā tātari rahi matūriki laser, ngā ine fluorescence X-ray (XRF), me ngā mita mā hei whakarite kia tutuki i ngā paerewa ahumahi. Ka tutuki i tā mātou paura talc taumata ahumahi ngā tiwhikete ISO 9001, REACH, me RoHS, me te whakarite kia piri ki ngā whakaritenga ture o te ao.
Ko te pono o ngā mahi kawe he wāhanga nui o tā mātou ratonga. Ka pupuri mātou i ngā taonga i roto i ngā whare putunga puta noa i Haina, me te whakarite kia 7–10 ngā rā e haere ana mō te nuinga o ngā ota. Ka tākaihia ngā hua ki roto i ngā putea pepa kraft 25kg, ki ngā putea nunui rānei 1000kg, me ngā kōwhiringa mō te tapanga ritenga. Ka whakahaerehia e mātou ngā tuhinga kaweake katoa, tae atu ki ngā tiwhikete tātari (COA) me ngā whakapuakitanga tikanga, e whakangawari ana i te tukanga kawemai mō ngā kiritaki i Ūropi, Amerika Te Raki, me Āhia ki te Tonga-mā-rāwhiti.
Me te arotahi ki te kounga, te whakaritenga, me te tautoko kiritaki, kua waiho tō mātou paura talc kounga ahumahi hei whiringa pono mā ngā kaihanga o te ao. Ka tukuna e ia he mahi pumau, he penapena utu, me te whai huatanga o te mahi—ka waiho hei rauemi tino nui i roto i ngā tukanga ahumahi hou.
