Ko te pūwhakahaere pahuka he tāpiri matū e whakamahia whānuitia ana, he mea nui ki ngā mahi ahumahi maha, inā koa i roto i te hanga kirihou pahuka me ētahi atu rauemi kei roto he mirumiru. Ko ngā tikanga matua o te mahi a ngā pūwhakahaere pahuka e whai ake nei:
Whakaitihia te kume o te mata o ngā wai
Ko ngā kaiwhakahaere pahuka he matū horoi i te nuinga o te wā ka taea te whakaiti i te taumahatanga o te mata o ngā wai. Mā tēnei āhuatanga ka māmā ake te hanga mirumiru pumau mō ngā wai. Ina tāpirihia ngā kaiwhakahaere pahuka ki te wai, ka hangaia he kiriata angiangi ki te mata o te wai e ārai ana i ngā ngota hau ki te tomo ki roto i te wai. Ina whakaohokia, ina rūrūtia rānei te wai e te kaha o waho, ka mau te hau ki roto i te wai, ka hanga he pahuka 1.
Whakaputa hau
Ko ētahi momo kaiwhakahaere pahuka, inā koa ko ngā matū pahuka, ka whakaputa hau mā roto i ngā tauhohenga matū. Ka hangaia e ēnei hau he mirumiru i roto i te wai, ā, ka puta he pahuka. Me whakahaere tika te whakamahinga o te matū pahuka, nā te mea ka raru pea te pahuka i te nui rawa o te hau, ka pakaru rānei.
Te huka ā-tinana
Hei tāpiritanga, ka whakauruhia e ētahi kaiwhakahaere pahuka te hau ki roto i te wai mā roto i ngā tikanga ā-tinana, pērā i te whakaoho, te kutikuti tere rānei, hei hanga pahuka. Ko te tikanga, me whakamahi he taputapu me ngā tikanga motuhake mō tēnei tikanga kia ōrite te tohatoha o te hau i roto i te wai.
Whakapai ake i te hanganga pūtau me te matotoru o te pahuka
I roto i te hanga rauemi pahuka pūmua, ka taea e ngā kaiwhakahaere pahuka te whakapai ake i te hanganga pūtau me te mātotoru pahuka. Mā te whakarerekē i te momo me te nui o te kaiwhakahaere pahuka, ka taea te whakahaere tika i te taumata whānui me te hanganga pūtau o te pahuka o te pūmua, kia tutuki ai te mahi motuhake e hiahiatia ana. Hei tauira, ka taea e te meta polyanhydride te whakarerekē i te hanganga me te rahi o te pūtau o te pahuka iti-mātotoru, i te mea ka taea e te kapia phenolic te whakahaere i te whānui o te pūmua me te hanganga pahuka2.
Whakapai ake i te kaha rewa me te rere o te wai
Ko tētahi o ngā take o te tāpiri i ngā pūmua taumaha-ira tino teitei ki ngā hua pahuka PVC ko te whakapai ake i te kaha rewa o ngā rauemi pahuka PVC, te ārai i te hanumi o ngā mirumiru, me te whiwhi hua pahuka ōrite. I taua wā anō, ka whakarite hoki tēnei kia pai te rere o te rewa kia puta ai ngā hua he āhua pai.
whakatau
He maha ngā tikanga e whakamahia ana e ngā kaiwhakahaere pahuka, tae atu ki te whakaiti i te taumahatanga o te mata wai, te whakaputa hau, te whakaoho tinana, me te whakapai ake i te hanganga pūtau me te kiato o te pahuka. Ka mahi tahi ēnei tikanga kia whai wāhi nui ai ngā kaiwhakahaere pahuka ki te whakaputa i ngā momo mara, pērā i te kai, te whakapaipai, ngā matū o ia rā me ngā rauemi pahuka polymer. Heoi, i te wā e whakamahi ana i ngā kaiwhakahaere pahuka, me aro hoki ki ō rātou pānga ki te taiao, te haumaru, me te utu kia tutuki ai te whanaketanga pumau.
