He mahi nui tonu te PVC i roto i te hanga, engari ko tōna rekereke Achilles—te whakahekenga wera i te wā tukatuka—kua roa e whakararuraru ana i ngā kaihanga.ngā whakaū PVC konutea konutea wai: he otinga hihiri e aro ana ki ngā raruraru uaua rawa o te rauemi me te whakahaere i te whakaputanga. Me wehewehe tātou me pēhea te whakarerekētanga o tēnei tāpiringa i te hanga PVC.
Ka aukati i te pakaru o te wera i roto i ōna ara
Ka tīmata te pirau o te PVC i ngā pāmahana iti iho i te 160°C, ka tukuna te hau HCl kino, ka huri i ngā hua kia pakarukaru, kia ngaro rānei te tae. Ko ngā whakaū konutea konutea konutea wai he parepare tiaki, ka whakaroa i te pirau mā te whakakore i te HCl me te hanga i ngā matatini pumau me te mekameka pūmua. Kāore i rite ki ngā whakaū konganuku kotahi e tere memeha ana, ka tukuna e te huinga konutea konutea-konutea he tiaki roa ake—ka noho pumau tonu te PVC ahakoa i te wā e roa ana te weranga i te 180-200°C. Ko te tikanga he iti ake ngā puranga kua whakakahoretia nā te kōwhai, te ngatata rānei, inā koa i roto i ngā hua angiangi pēnei i ngā kiriata me ngā pepa.
Ka whakakore i ngā aukati tukatuka
E mōhio ana ngā kaihanga ki te whakarihariha o te whakaweto pinepine i ngā raina. He maha ngā wā ka waiho e ngā mea whakaū tuku iho he toenga ki runga i ngā mate me ngā tīwiri, ka aukati i te horoi i ia 2-3 hāora. Heoi, he iti te matotoru o ngā tauira konutea konutea wai e rere pai ana i roto i ngā taputapu, ka whakaiti i te kohikohinga. I kōrero tētahi kaihanga paipa kua tapahia te wā horoi mā te 70% i muri i te whakawhiti, ka piki ake te putanga o ia rā mā te 25%. Ka konatunatua ōrite te ahua wai ki te kapia PVC, ka whakakore i te puranga e hua ai te matotoru koretake i roto i ngā kōtaha, i ngā paipa rānei.
Ka whakanui ake i te pakari o ngā hua whakamutunga
Ehara i te mea ko te hanga anake te mea nui—he mea nui anō hoki te mahi o te whakamahinga whakamutunga. Ko ngā hua PVC kua rongoatia kingā kaiwhakaū konutea konuteae whakaatu ana i te ātete pai ake ki ngā hihi UV me te makuku, e whakaroa ana i te roanga o te ora i roto i ngā tono o waho pēnei i ngā anga matapihi, i ngā ngongo māra rānei. I roto i ngā hua ngāwari pēnei i ngā gaskets, i ngā ngongo hauora rānei, ka mau tonu te ngāwari o te whakaū i roto i te wā, ka ārai i te whakapakeketanga e arahi ana ki ngā turuturu, ki ngā pakaru rānei. E whakaatu ana ngā whakamātautau ka mau tonu ēnei hua i te 90% o ō rātou kaha kume i muri i te 500 hāora o te koroheketanga tere, he pai ake i ērā i hangaia me ngā tāpiringa tuku iho.
E tutuki ana i ngā Paerewa Haumaru Tino Pai
Kei te piki haere te pēhanga ture mō ngā tāpiringa PVC haumaru ake, inā koa i roto i ngā hua e pā ana ki te kai, i ngā hua hauora rānei. E tutuki ana ngā whakaritenga katoa i roto i ngā whakaū konutea konutea wai: kāore he konganuku taumaha pērā i te mata, i te cadmium rānei, ā, nā te iti o te tere hekenga ka noho rite tonu ki ngā ture a te FDA me te EU 10/2011. Kāore i rite ki ētahi whakaū rauropi e tango ana i ngā matū, ka mau tonu tēnei tauira ki roto i te whāriki polymer—he mea nui mō ngā tono pērā i te takai kai, ngā taonga takaro rānei a ngā tamariki.
He Whai Hua te Utu, Kāore he Whakakorenga
Ko te huri ki ngā tāpiringa kounga teitei he tikanga he nui ake ngā utu, engari kāore i konei. Ko ngā pūmau konutea konutea wai e hiahia ana kia 15-20% te iti iho o te horopeta i ngā mea totoka hei whakatutuki i ngā hua ōrite, ka tapahia ngā whakapaunga rauemi mata. Ka whakaitihia hoki te whakamahinga pūngao e tōna whai huatanga: ka whakaitihia e te tukatuka maeneene ngā pāmahana whakaputa mā te 5-10°C, ka tapahia ngā pire ratonga. Mō ngā kaihanga iti ki te rahi waenga, ka tere te tāpiri o ēnei penapena—he maha ngā wā ka whakahokia mai te utu whakawhiti i roto i te 3-4 marama.
He mārama te karere: kāore ngā wai whakaū konutea konutea e whakatika noa i ngā raruraru o te PVC—ka tautuhi anō i ngā mea ka taea. Mā te whakakotahi i te tiaki wera, te pai o te tukatuka, me te haumaru, kei te noho hei whiringa matua mā ngā kaihanga e kore e pai ki te whakarērea te kounga mō te utu. I roto i te mākete e kore e taea te whiriwhiri i te pono me te tutuki i ngā whakaritenga, ehara tēnei tāpiringa i te whakapai ake noa—he mea nui.
