Rārangi Tara i te PVC-O mō te Tukatuka Wai Mātua Haumaru

Me pēhea te whakamātautau pūpū PVC-O e whakamāhi ana i te haumātua o ngā wai inaianei

Te whakarerekētanga ā-tārua: Te whakamāhinga i te PVC-U ki ngā pūpū PVC-O kaha, kore whakamāhinga

Ko te Polyvinyl Chloride Bi-Axially Oriented, ko te PVC-O rānei, e kiia nei he mea noa, ka tango i te rauemi PVC-U noa, ka hurihia mā ētahi huringa ngota tino whakamīharo. I te wa e hanga ana i ēnei putorino, ka totoro rātau i ngā taha e rua i te wā kotahi i te tukanga whakawātea, me te pupuri tonu i ngā pāmahana tika. Mā tēnei whakawhitinga e whakarōpū i aua rāpoi ngota pūmua roa ki tētahi mea tino pai ake te whakarite me te hono puta noa i te rauemi. He aha te tikanga o tēnei? Well, ko te PVC-O ka mutu kia 50% te kaha ake i te PVC-U paerewa engari ka taea tonu e ia te whai i nga pakitara angiangi, e māmā ake ai te kawe me te tāutanga. Ko tētahi painga nui mai i te āhua o tēnei aronga e mahi ana i tōna mīharo, e whakakore ana i ngā wāhi iti i roto i te rauemi e taea ai te kohikohi paru. Engari ka whiwhi tatou i tētahi mata mārō, kāore e whakahohe, e aukati ana i ngā matū kino pēnei i ngā mea whakakakara i te rere ki te wai. E whakaatu ana ngā whakamātautau i mahia e ngā rōpū tuatoru e tutuki ana te PVC-O i ngā paerewa NSF/ANSI 61 e hiahiatia ana mō ngā tono wai inu, ā, ka noho pūmau ahakoa ka whakapā ki te wai me ngā taumata pH e huri ana i ngā wāhi katoa i waenganui i ngā āhuatanga tino waikawa me te tino waikawa.

Ngā mana whakahaere tukanga matua: Te whakaahuatanga o te pāmahana, te ōwehenga hopu, me te pūmautanga o te whakawera

Ko te mahi haumaru-matatini ōrite e whakawhirinaki ana ki ngā tawhā whakawātea tino whakahaere:

• Te tātai pāmahana ka mau tonu te ōrite o te ±2°C i te wā o te whakaarokore kia kore ai e puta ngā hapa kiriāura
• Te whakamātautau o te whakamātautau o ngā whāinga (te tikanga 1.5:1 radial / 1.2:1 axial) e whakarite ana i te whakatikatika ngota pai rawa atu me te kore e whakaara i te ahotea o te hanganga
• Te whakakakara i ngā wāhanga maha ka whakaiti i ngā taumahatanga ā-roto me ngā here i roto i ngā painga arongawhakatautia mā te tātuhi i ngā taumahatanga toenga

Ko ngā rerekētanga neke atu i te 5% i ēnei tawhā ka whakaiti i te ātete pānga ki te 30% me te roa o te ngoikore ki te 40%. Ka whakauruhia e ngā raina whakawātea hou te pūāhua-a-taima me ngā pūoko matotoru-pōro hei pupuri i te ūnga ki ngā whakakahoretanga ISO 16422e whakarite ana kia tukuna e ia putorino he kawe wai pono, kore-kino.

Ko te whakatutukitanga o te mahi me te whakatutukitanga o te paipa PVC-O i roto i ngā pūnaha wai inu

Te whakatikatika ture: NSF/ANSI 61, ISO 16422, ASTM F1482 me IS 15956

Ko ngā pīpī PVC-O i whakamānaitia ki ngā whakamārama ā-motu mō te haumātua o te wai inānia—ki tēnei hoki ko ngā whakamārama NSF/ANSI 61 (mō te whakamāhinga), ISO 16422 (mō ngā whakamārama o ngā kōpae), ASTM F1482 (mō te whakamāhua), me IS 15956 (te whakamārama o Tiamani). Ko te whanonga o te whakamāhunga e tēnā rōpū e whakamātua ana kia mau tonu te whakamāhinga i raro i te 0.01 ppm mō ngā kōpae kua whakaritea, pērā i te chloride vinyl, kia whakamāna ai te wai mātātoko mai i te wāhi taketake ki te tapa.

Te whakamātua i te whakamāhinga me te whakamātua kore i te whakamāhinga hei whakamātua mo te whakamāhua roa o te wai inānia

He āhuatanga motuhake tēnei o te PVC-O ki te aronga rua e āhei ai te aukati i ngā raruraru waikura hiko. Kāore he raruraru o te waikura, o te whakaiti, o ngā mate pukupuku e pā ana ki ngā putorino whakarewa i te wā. Kua mahia ētahi whakamātautau pakeke tere, kāore i kitea he tohu o te heke o te kirihou ahakoa i muri i te whakaata i te 50 tau o te whakamahinga. Ko te tikanga he reka tonu te reka o te wai, he hau noa, ā, kāore e riro hei wāhi whakatipu mō ngā huakita. I te titiro ki ngā tono tūturu, e pūrongo ana ngā kamupene e huri ana i ngā pūnaha rino ātaahua tuku iho e whakaiti ana i ō rātou utu tiaki ki te 43 ōrau i runga i te wā roa. I whakaputaina e te Water Research Foundation ēnei kitenga i te tau 2023, e whakapūtā ana i te mea e kite kē ana ngā kaipūkaha me ngā kaipūkaha i te pae.

Te Pūmau Hangarau: Me pēhea te Whakatika i te PVC-O Pipe >100-Tau Te Ora Ratonga

Te Whakakorea i te Ngaru me te Whakakorenga Hydrostatic: Raraunga mai i nga Whakatairanga Marae o Ahitereiria me UK

I roto i ngā tono ā-rohe, ka kite mātou i te kaha o te PVC-O. Kua kitea e ngā kamupene wai puta noa i Ahitereiria kei te pupuri tonu a rātau putorino i te 94% o to rātau kaha pakaru taketake ahakoa i muri i te haurua rau tau i raro i te whenua. He ōrite ngā hua i te UK, kei reira ngā pēhanga o te pēhanga e noho ana i runga ake i te mea i whakaritea i te tuatahi ahakoa he maha nga tau o te mahi. E whakaatu ana hoki ngā whakamātautau motuhake i tētahi mea whakahirahira: Ka taea e te PVC-O te whakahaere i te 10 miriona huringa taumaha i ngā pēhanga whakahaere noa. Ko tēnei mahi whakamiharo ka heke iho ki te whakaheke i te whakaheke i te kiripuku i whakaritea ki nga rauemi PVC-U noa, tata ki te 70% iti iho i te mea. Ko te paparanga motuhake i roto i te rauemi e āwhina ana ki te hopu i te pānga ina neke te whenua, ka puta rānei ngā huringa ohorere i te rere o te wai, ko te tikanga he iti ake te āhua o ngā pakaru, ā, ka noho tonu te pūnaha i raro i te pēhanga. I te titiro ki ngā whakaaturanga o te ao tūturu, ko te nuinga o ngā tāutanga e pupuri ana i te 98% o to rātau kaha pēhanga i muri i te 50 tau o te mahi, e whiua ana ētahi atu kōwhiringa putorino e ai ki ngā aromatawai a ētahi atu rōpū tuatoru i roto i te wā.

Te Whakamātautau i te Wā Tūmati o te Whananga o ngā Pīpī PVC-O

Ko te whakamātua i ngā rākau whakamātautau pūkenga te i whakamāngai ai i te hāhanga o PVC-O, ā, i huri ai i tēnei i tā mātou kī ai he rākau whakamātautau kāpae. Ko ngā micrometers lāser e whakamātautau ana i te pāpaku o te pāpaku o te tāwhai i tēnei wā i te 0.1 mm, ā, ko tēnei i te mea i whaihanga i tēnei i mua i te whakamātautau ā-ringa. I tēnei wā anō, ko ngā kārihi ultrasonic e whakamātautau ana i ngā hapa kūkū i raro i te whaitua e kore pea e kitea i tēnei āhua o te hua. He whakamātautau ā-wā i tēnei wā i ngā wāhi kāore i kitea e te kanohi. Ko tēnei i whakamāngai ai i te whakamātautau i ngā molekini kia tika i te wā o te whakamātautau, ā, ko tēnei e whāia ana i te whakamātautau o te pūmau o ngā hua o te wāhi, me te kaha o te hua whakamutunga. Mēnā he aha ngā mea e wātea ana mai i ngā whakamātautau ISO 16422, ka whakamāngai ai te rākau i ngā whakamātautau o te whakamātautau i mua i te whakamātautau o ngā huinga kino. Ko ngā hāhanga katoa mai i te wā i tāwhai ai te resin i te whare, i tēnei wā ki te wā i tāwhai ai ngā hua, kua tuhia katoa i te rorohiko. Ko ēnei tuhinga e whai ana i ngā whakamātautau o NSF/ANSI 61 me ētahi atu i te ao mō ngā whakamātautau mō te wai inānia. I tēnei wā, i tēnei whakamātautau katoa, ka whakamāngai ai i te whakamātautau o ngā rākau i te 18% i ngā hāhanga o mua. Ko te mea nui, ko tēnei e whakamāngai ai kia kāore he whakamātautau i te wāhi katoa o ngā tau 100 e whakamāngai ai ngā hua.

Ngā Pātai Tāwhai i te Whakamāhi i te Pūnaha Whakamātautau PVC-O

1. Me pēhea te whakamārama o te PVC-O i te haumātua o te wai kai?

Ko ngā tārua PVC-O e whakamātautia ana i te rere o ngā mōhini ā-pū, ā, ko tēnei he rere ā-rua e whakamārama ai i ngā mōhini kia pūmau, kia kore ai te whakamātau. Ko tēnei rere e whakakaha ake ana i te kaha o te PVC-U tāwhai i te 50% i te tārua, ā, he whakamāngō hoki i ngā wāhi e whai ana i te whakamātau, he iti ake hoki te whakamātau i te whakamātau, ā, he whakamārama hoki i ngā whakamātautau NSF/ANSI 61 mō te wai kai.

2. He aha te mea i whakamārama ai te PVC-O i te whakamātau?

Ko te whakamārama ā-rua o te PVC-O he whakamārama i te whakamātau ā-hiko, ā, he whakamāngō hoki i ngā raru pērā i te rino me ngā whakamātau i ngā tārua rino. Ko tēnei he whakamārama i te roa o te whakamāhi, kāore he whakamātau, ā, he whakamārama hoki i te haumātua o te wai.

3. Me pēhea te whakamārama i te kounga i te whakamāhi i ngā tārua PVC-O?

Ko ngā pūnaha whakamātautau pāpātanga, tātai hoki i ngā micrometers lazer me ngā kākāhi ultrasonic, e whakamahinga ana i te whanonga hei whakamātau i ngā whakamātautau ISO 16422. Ko ngā whakamātua i te wā-ao hei whakamātau kia kore he hapa, ā, ko ngā kōrero matua mātātoko e whakamātau ana i te whakamātautau ki ngā whakamātautau wai inānia.

4. He aha ngā whakamātautau rāwhiti e whakamātua ana e ngā kōwae PVC-O?

Ko ngā kōwae PVC-O kua whakamātua hei whakamātau i ngā whakamātautau NSF/ANSI 61, ISO 16422, ASTM F1482, me IS 15956, kia whakamātua ai he haumaru, he tino pūmau hoki mō ngā whakamāhi wai inānia.

5. E hia ngā tau o te ora o ngā kōwae PVC-O?

Ko ngā kōwae PVC-O i whakamahinga hei whakamātau i te tāwhai, ā, ko ngā raraunga mai i ngā whakamāhi i te ao e whakaatu ana i tā rātou whakamātau i te kapua wāhi me te tāwhai o te hanga i ngā tau maha o te whakamāhi, e whakaatu ana i tēnei he ora o te whakamāhi i te rere kōrero i te 100 tau.
