Kei te titiro koe ki ngā whakatakotoranga paipa, ā, ka kite koe i ngā waehere pēnei i te PE80 me te PE100. He pōhēhē tēnei kupu hangarau, ā, mā te whiriwhiri i te momo hē ka raru pea te pumau o tō kaupapa mō te wā roa.

Ko te tikanga o te PE100 he mea hanga te paipa mai i te whakatupuranga hou o te Polyethylene Matotoru-Teitei (HDPE). Ko te "100" e tohu ana i te Kaha Whakamutunga e Hiahiatia ana (MRS) o te 10.0 MPa. Nā tēnei ka kaha ake, ka roa ake te mau, ka taea ai te hanga i ngā pakitara paipa angiangi i te taumata pēhanga ōrite.

Ina kōrero ahau ki ngā kaiwhakahaere hoko pēnei i a Budi, he kaupapa auau ēnei tohu rauemi. He māmā noa te kite i a rātou he tau noa iho, engari ko te "PE100" e tohu ana i ngā tekau tau o te whanaketanga o te pūtaiao rauemi. He kupu whakaari mō te kaha, te pono, me te mahi roa. Ko te mārama ki te tikanga o tēnei waehere māmā te mea nui ki te whakatau hoko atamai e whakarite ana i te angitu o ō pūnaha whakahaere wai mō ngā tau e haere ake nei. Me wehewehe tātou i te tikanga tūturu o tēnei tohu mō ō kaupapa.

He pai ake a PE100 i te PVC?

He rauemi mōhiotia te PVC, ā, he iti ake te utu i mua. Nā tēnei ka whakamātauhia te whiriwhiri, engari nā te pakari me te tikanga honohono ka ara ake pea ngā raruraru ā muri ake nei me te pikinga ake o ngā utu whānui.

Mō ngā puna wai tanumia, he pai ake te PE100. Nā tōna ngāwari, tōna ātete pānga teitei ake, mengā hononga honohono ātete-taurakituku pono mō te wā roa. Ko ngā hononga whakarewa-whakarewa, ngā hononga gasket rānei o te PVC te nuinga o te wā te ngoikore rawa o te pūnaha, he raruraru ewhakarewa honohonowhakakore rawatia.

Ahakoa he pai ngā rauemi e rua mō ētahi whakamahinga, ka kitea ngā rerekētanga matua i roto i ngā āhuatanga uaua. Ko te painga nui o te PE100 ko te tikanga honohono. Ina whakamahanahia he paipa HDPE, ka noho te hononga hei wahi kirihou kotahi, totoka, he kaha rite tonu ki te paipa tonu. Kāore e turuturu. Ko ngā hononga PVC, e whakawhirinaki ana ki te sima whakarewa, ki ngā gasket rapa rānei, ka puta he wāhi pakaru pea. I roto i te wā, ka taea e te nekehanga whenua me ngā huringa pēhanga te whakararu i ēnei hononga. Mā te ngāwari o te PE100 ka taea hoki te tāutanga kore-awa, ka taea te whakaiti i te wā me te utu hanga, he painga nui i roto i ngā tāone nui. Ko te PVC, he pakari, me keri tuwhera-awa tuku iho, he mea whakararuraru ake, he utu nui ake hoki.

He aha te rerekētanga i waenganui i te PE 80 me te PE100?

E rua ngā kīanga ka kitea, tētahi mō ngā paipa PE80, tētahi mō te PE100. He tata tonu ngā tau, engari mā te whiriwhiri i te paipa iti ake hei penapena moni, tera pea ka tāutahia he paipa ngoikore ake.

Ko te tau e pā ana ki te Kaha Rawa e Hiahiatia ana (MRS) i muri i te 50 tau. Ko te MRS o te PE100 he 10.0 MPa, ko te PE80 ia he 8.0 MPa. Mā te pikinga 25% o te kaha ka taea e ngā paipa PE100 te whai angiangi ake i ngā pakitara mō te whakatauranga pēhanga ōrite.

TeTe Kaha iti rawa e hiahiatia ana (MRS)he uara e whakaahua ana i te kaha mō te wā roa o te rauemi. Ka whakatauhia e ngā kaipūtaiao mā te pēhanga i te paipa, me te ine i te roa o te wā e pakaru ai, kātahi ka whakamahia aua raraunga hei matapae i tōna kaha mō te 50 tau te roa o te ora ratonga. Ko te teitei ake o te MRS, ko te kaha ake o te rauemi.

Mā tēnei painga kaha 25% o te PE100 i te PE80 ka hoatu ki a koe ngā painga nui e rua. Tuatahi, mō tētahi paipa he rite te matotoru, ka taea e te PE100 te tu atu ki tētahi pēhanga teitei ake. Tuarua, ā, he mea nui ake mō te penapena moni, ka taea e koe te whakamahi i tētahiPaipa PE100 me te pakitara angiangikia rite te pēhanga ki te paipa PE80 matotoru. He angiangi ake te pakitara, ā, he iti ake ngā rauemi mata e whakamahia ana, ā, ka māmā ake te paipa, ka iti ake hoki te utu. He iti ake te utu mō te kawe i te paipa māmā ake, ā, he māmā ake te whakahaere i te wāhi mahi. Ka nui ake hoki te diameter o roto o te pakitara angiangi, ka pai ake te rere o te wai, ā, ka whakaiti i ngā utu papu i te roanga o te pūnaha.

Ko tēhea te mea pai ake, HDPE, PE rānei?

He maha ngā wā ka whakamahia ngā kupu PE me HDPE i roto i te kōrero kotahi. Ka pōhēhē pea tēnei, ka whakaaro koe kei te whakataurite koe i ngā rauemi e rua tino rerekē, engari ehara i te mea pērā.

He pātai tinihanga tēnei, nā te mea he mea motuhake te HDPE (High-Density Polyethylene)momoo te PE (Polyethylene). Ko te PE te ingoa whānau whānui. Mō ngā paipa pēhanga mō te wai me te hau, ko te HDPE te kōwhiringa tika me te pai rawa atu nā tōna kaha me tōna roa.

Whakaarohia te "Polyethylene" (PE) hei ingoa whānau mō tētahi rōpū kirihou katoa. I roto i tēnei whānau, he maha ngā momo rerekē i runga i tō rātou kiato ngota, e whakatau ana i ō rātou āhuatanga ā-tinana.

• PE (Polyethylene):Te kāwai whānui.
• LDPE (Polyethylene Matotoru-Iti):He tino ngāwari, e whakamahia ana mō ngā mea pēnei i ngā putea kirihou me ngā kiriata. Kāore e pai mō ngā paipa pēhanga.
• HDPE (Polyethylene Matotoru-Teitei):He tino kaha ake, he pakari ake, he mārō ake. Koinei te rauemi paerewa mō ngā paipa pēhanga e whakamahia ana i roto i te tuku wai, te tohatoha hau, me ngā mahi ahumahi.

Nō reira, ina kōrero tātou mō ngā paipa PE i roto i te horopaki o te whakahaere wai, e kōrero ana tātou mō ngā paipa HDPE. Ko ngā momo i kōrerohia i mua ake nei, ko te PE80 me te PE100, he whakarōpūtanga mahi motuhake o te kapia HDPE. Nō reira, ehara te pātai i te "HDPE, i te PE rānei?" engari, "Ko tēhea momo o te HDPE e tika ana mō taku kaupapa?". Mō tētahi tāutanga hou, ko te momo PE100 HDPE te kōwhiringa pai rawa atu.

Ka taea te whakarewa i te PE80 ki te PE100?

Me whakatika e koe tētahi paipa wai tawhito i hangaia ki te PE80. Ko tō pūnaha hou he PE100 katoa. Mēnā ka hē te hononga i waenganui i ngā rauemi e rua, ka raru pea te ratonga.

Ae, ka taea e koe te whakarewa tika i te PE80 ki te PE100. Nā te mea nō te whānau polyethylene rāua, ka honoa ngā kirihou. Heoi, me whakamahi koe i ngā tawhā whakarewa mō te PE80 kounga iti, ā, ka rite te kaha o te hononga ki te hononga PE80.

He pātai tino nui tēnei mō ngā mahi tiaki me ngā mahi whakatika. Ko te kaha ki te hono i ngā momo rerekē he painga nui o te HDPE. Nā te mea he mea hanga te PE80 me te PE100 mai i te pūhui turanga kotahi, he hototahi ō rāua hanganga ngota, ā, ka hanumi ngātahi i te wā e whakarewahia ana te wera hei hanga i tētahi hononga kaha, pumau.

Heoi anō, kotahi te ture nui me whai e koe:me whakamahi tonu i ngā tawhā whakarewa (te pāmahana, te wā, me te pēhanga) kua tohua mō te rauemi kounga iti.He rerekē ngā whanonga rewa o te PE80 me te PE100, ā, mā te whakamahi i ngā tautuhinga mō te PE100 ka wera rawa, ka kino rānei te pito o te paipa PE80, ka ngoikore te hononga. Ko te tuarua o ngā mea hei maumahara ko te kaha o te pūnaha he rite tonu ki tōna hononga ngoikore. Ka rite te whakatauranga pēhanga me te mahi o te paipa PE80 ki te hononga whakarewa me te wāhanga paipa katoa, ehara i te PE100. Ahakoa mō ngā kaupapa hou ka tūtohu tonu mātou i te PE100, he tino pai tēnei hototahi mō te whakawhānui, te whakatika rānei i ngā hanganga tawhito.

Whakamutunga

PE100ehara i te mea he waehere noa iho; he momo HDPE mahi-teitei. Nā tōna kaha me tōna pono teitei i waiho ai hei paerewa hou mō te hanga paipa wai haumaru, roa hoki.
