He aha ngā tikanga hei whakamahi i ngā kaiwhakahaere pahuka PVC?

I roto i te tātai pahuka PVC, kia whiwhi ai i tētahi hua hanganga pūtau ōrite, pai, me te motuhake, hei tāpiri atu ki te whakamahi i ngā whakarerekētanga pahuka pēnei i ngā āwhina tukatuka ACR, ka whakamahia hoki ngā whakarerekētanga pahuka PVC i roto i te tātai. I ētahi wā, ka tāpirihia hoki ngā whakatere pahuka pēnei i ngā waikura whakarewa pēnei i te waikura konutea me te waikura mata, ngā tote waikawa waro pēnei i te konutea stearate, me ngā hua urea (hei whakatika i te pāmahana pirau o te kaihoko pahuka). Ko te horopeta o te kaiwhakahaere pahuka he 4% -8% (i runga i te ihirangi kapia katoa), me taurite te kaha ki ngā kaihoko pahuka (pēnei i te kaihoko pahuka kōwhai AC, te kaihoko pahuka mā NC). Ko te hanga pereti matotoru me whakanui ake i te ōwehenga o te kaihoko pahuka NC pāmahana-iti (ōwehenga noa o te 1.2 wāhanga NC+0.5 wāhanga AC) kia kore ai e tukuna te hau kukū i te wāhanga o muri mai ka arahi ki te pakaru o te pahuka; Ko te whakahaere kiato me whakataurite te whakaputanga hau me te pāmahana pirau.
Ko te pūwhakahaere pahuka PVC he pūhui hinu kiriaku. Kei a ia ngā āhuatanga katoa o ngā āwhina tukatuka PVC, engari he nui ake tōna taumaha ngota i te taumaha ngota o ngā āwhina tukatuka PVC. I roto i te tukanga pahuka PVC, mā te tāpiri i te pūwhakahaere pahuka PVC ka taea te whakanui ake i te kaha rewa o ngā hua PVC, ā, ka ārai i te hanumi o ngā mirumiru, ka puta he hua pahuka PVC kua rite te pahuka. I taua wā anō, ka taea hoki e ia te whakatairanga i te kirihou o te PVC, me te whakarite kia pai te rere o te rewa.
I te wā e whiriwhiri ana i ngā whakarerekētanga pahuka PVC, me aro ki te whakamahi i ngā whakarerekētanga pahuka rerekē mō te PVC me ngā nekehanga polymerization rerekē, pērā i te PVC-700, PVC-800, me te PVC-1000. He rerekē ngā momo hua, pērā i ngā papa pahuka, ngā papa matotoru pahuka, ngā papa angiangi pahuka, ngā papa pahuka rakau kirihou, ngā papa pahuka kirihou mata, me ētahi atu, me whakamahi i ngā whakarerekētanga pahuka rerekē. Nā te mea he matū kiriaku anō hoki ngā kaihoko pahuka PVC me ngā āhuatanga āwhina tukatuka, me aro anō hoki ki te taurite whakahinuhinu ā-roto me ā-waho o te tauira i te wā e whakamahia ana. Ka tutuki i te Bangtai Petrochemical Foam Regulator ō hiahia maha mō ngā hua. Mō ētahi atu pātai hua mō ngā kaiwhakahaere pahuka PVC, tēnā waea mai!
