He mea nui te whiriwhiri i te rauemi paipa tika mō te angitu o te kaupapa mō te wā roa. E āwangawanga ana koe kei huna ngā tūponotanga i ngā kupu uaua pēnei i te "PE100".Ko te PE100 te paerewa hou mō ngā paipa kirihou kaha-teitei.

He paipa pēhanga te paipa PE100 i hangaia mai i te Polyethylene Matotoru-Teitei (HDPE) kounga teitei. Ko te "100" e tohu ana i tōna Kaha Whakamanahia Iti rawa (MRS) kua whakamanahia he 10 MPa, e whakamana ana i tōna kaha ki te tu atu ki te pēhanga teitei mō ngā tau neke atu i te 50, he mea tino pai mō ngā hanganga nui.

Hei kaihanga pūnaha paipa mō te tata ki te rua tekau tau, kua whakatūria e au taku pakihi i runga i te kaupapa kotahi: ko te pono ka tīmata i te rauemi mata. Ehara a PE100 i te ingoa noa iho; he paerewa ā-ao e whakawhirinakihia ana e mātou me ā mātou kiritaki. Mō ngā tohunga pēnei i a Arief, he kaiwhakahaere hokohoko matua i Indonesia, he taurangi tēnei tiwhikete. Ko te tikanga he kaha hangarau te paipa e tāutahia ana e ia mō te pūnaha wai ā-tāone hei pumau mō ngā whakatipuranga. Me titiro hohonu ake tātou ki te tikanga o tēnei paerewa me te take he mea nui mō āu kaupapa.

He rite tonu te HDPE ki te PE100?

Ka kite koe i te HDPE me te PE100 e whakamahia ana i roto i ngā whakaritenga, ā, kāore i te mārama he aha te rerekētanga. Nā tēnei whakapoauautanga ka uaua te whakataurite i ngā rauemi.He putanga HDPE kounga teitei noa iho a PE100.

Kāo, ehara i te mea ōrite katoa. He HDPE ngā PE100 katoa, engari kāore ngā HDPE katoa e tutuki ana i te paerewa PE100. Ko te PE100 he whakarōpūtanga motuhake o te Polyethylene Matotoru-Teitei kua whakamanahia he kaha ake, he ātete hoki ki te pakaru i ngā momo HDPE tawhito.

Whakaarohia te "HDPE" hei ingoa mō tētahi whānau nui, kanorau. I roto i tēnei whānau, he rerekē ngā whakatupuranga, he pai ake ngā āheinga o ia whakatupuranga i ērā o mua. Ko ngā paipa pēhanga tuatahi i hangaia mai i ngā momo pēnei i te PE63. Kātahi ka pai ake te hangarau, ā, i whakawhanakehia e mātou te PE80. I ēnei rā, ko te PE100 te paerewa hou, te paerewa mahi-teitei. Ko te tau i roto i te ingoa e whakaatu ana i tōna kaha mō te wā roa. Nō reira, ahakoa ka hangaia he paipa mai i te kapia HDPE whānui, ko teReini kua whakamanahia e te PE100kua oti te kī taurangi kia tutuki i taua paearu kaha teitei. Ina hangaia e mātou ngā paipa pēhanga i tō mātou whare, ka whakamahia e mātou te kapia PE100 tauhou anake. He wāhi whakahaere kounga nui tēnei. Mā tēnei ka whakarite kia whai hua ia mita o te paipa i te mahi matapae, whaimana e hiahiatia ana e ngā kaupapa hanganga. Ka whakakorea te whakapae mō te kaha me te roa o te rauemi.

Te Whakataurite i te HDPE Whānui ki te PE100 Whaimana

He aha te rauemi PE100?

Ka rongo koe i ngā momo rauemi rerekē, engari tera pea te "PE100" he rite noa ki te tau. Tērā pea ka wareware koe ki tōna painga nui.He kupu whakaari tika te kounga mō te kaha mō te wā roa.

Ko te PE100 te taumata rauemi he whakarōpūtanga ā-ao mō te kapia HDPE e tohu ana i te Kaha Whakahirahira e Hiahiatia ana (MRS) o te 10 Megapascals (MPa). Mā tēnei taumata ka oati te kaha o te rauemi ki te ātete i te pēhanga ā-roto mō te roanga o te ora ratonga 50-tau me te kore e pakaru.

Ko te "100" te wāhanga nui rawa atu o te ingoa. I ahu mai i te whakatauranga 10.0 MPa. Mā tēnei whakatakotoranga hangarau ka taea e ngā kaihoahoa te tatau i te kaha pēhanga o te paipa me te tino maia. He painga tino mahi tēnei e mōhiotia tonutia ana e ngā kaiwhakahaere hoko me te papamuri hangarau: ka pā ki te matotoru o te pakitara o te paipa. Nā te mea he kaha ake te PE100 i ngā momo tawhito pēnei i te PE80, ka taea e ia te whakahaere i te pēhanga kotahi me te pakitara angiangi. Ka inehia e mātou tēnei me te Paerewa Ahu (SDR), arā, te ōwehenga o te diameter o te paipa ki tōna matotoru pakitara. Mō tētahi akomanga pēhanga kua hoatu, ka nui ake te SDR (pakitara angiangi) o te paipa PE100 i te paipa PE80. Ko te tikanga he iti ake ngā rauemi mata e whakamahia ana, ka māmā ake te paipa, ka iti ake te utu, ka ngāwari ake hoki te whakahaere me te tāuta. Ka hua ake hoki he poka ā-roto nui ake, ka whakapai ake i te kaha rere.

Painga PE100: Ngā Pakitara Angiangi, Ngā Rere Pai Ake

He aha te matotoru o te rauemi PE100?

Kei roto i te ingoa te kupu "High-Density", engari he āhua uaua te āhua. Ki te kore e mārama ki tōna tikanga, kāore e taea te mārama he aha i tino pai ai te mahi a te rauemi.Ko te matotoru te pūtake o tōna kaha.

He Polyethylene Matotoru-Teitei te PE100, ā, ko tōna matotorutanga rauemi ka taka ki te awhe o te 0.95 ki te 0.97 karamu ia henimita kūpiko (g/cm³). Nā tēnei matotorutanga teitei ka pakari, ka kaha te kume, ka ātete matū pai rawa atu ki te rauemi.

Mai i te tirohanga hangahanga, ko te kiato te mea nui. Ka hangaia e mātou tēnei kiato teitei i te taumata ngota. He mekameka roa o ngā ngota te mea hanga o te polyethylene. I roto i te Polyethylene Kiato Teitei, he tino tika ēnei mekameka, he iti noa ngā peka. Mā tēnei ka taea e rātou te piri tahi me te hanga i tētahi hanganga tioata. Ko tēnei piri te tikanga o te "kiato teitei". Koinei te take he kaha, he pakari hoki te rauemi. He rerekē, he maha ngā mekameka o te Polyethylene Kiato Iti (LDPE). Ka ārai ēnei peka i ngā mekameka ki te piri tahi, ka hua ake he rauemi kiato iti ake, he ngawari, he ngāwari hoki, pērā i te putea kirihou. Mō tētahi paipa e hiahia ana kia mau te pēhanga ki raro i te whenua mō ngā tekau tau, me whai kaha koe e puta mai ana i taua hanganga piri, kiato teitei. Koinei te take matua he pai ake te PE100 mō ngā hanganga.

Te Mātotoru me tōna Pānga ki ngā Āhuatanga

He aha ngā ngoikoretanga o ngā paipa PE?

Kāore he rauemi e tino tika ana mō ngā āhuatanga katoa. Mā te kore e aro ki ngā herenga o ngā paipa PE ka arahi pea ki ngā hapa hoahoa, ki te tāutanga rānei, he nui te utu. Mā te mārama ki ōna ngoikoretanga ka taea e koe te whakamahi tika me te whai hua.

Ko ngā ngoikoretanga matua o ngā paipa PE ko tōna ngoikore ki te hihi UV me te kore he parenga, he iti ake te pāmahana whakahaere i te mea whakarewa, me te tere o te horapa wera. Me whai taputapu hanumi motuhake me ngā kaiwhakahaere whakangungu hoki te tāutanga tika.

Hei kaihanga, e whakapono ana ahau me pono te kōrero mō ngā herenga o tētahi hua. Ka hangaia he whakawhirinakitanga, ā, ka arahi ki ngā kaupapa pai ake. Tuatahi, he ngāwari ngā paipa PE kiTe pakaru o te hihi UV mai i te rā. Ka whakatauhia tēnei mā te tāpiri i te 2–3% o te pango waro ki te rauemi mata. Koia te take he pango tonu ngā paipa pēhanga; he kaha te mahi a te pango waro hei whakaū UV. Tuarua, he iti ake te awhe pāmahana i ngā paipa whakarewa. Kaua e whakamahia mō ngā tono wai wera i runga ake i te 60°C (140°F). Tuatoru, ka whānui, ka whakawhāiti hoki i ngā huringa pāmahana nui atu i te maitai, te rino ngāwari rānei. Mō ngā whakaurunga i runga ake i te whenua, me whakahaere tēnei mā te whakamahi i ngā koropiko whānui, i ētahi atu whakaaro hoahoa rānei. Mō ngā paipa tanumia, he iti ake te raruraru o tēnei. Hei whakamutunga, me whai tohunga hangarau whakangungu me ngā taputapu hanumi te hono i te HDPE. Ahakoa he āhua ngoikore tēnei, koinei anō tōna kaha nui rawa atu, nā te mea ka whakarite kia tino pai te hononga, kia kore e turuturu i ngā wā katoa.

Te Whakahaere i ngā Here o ngā Paipa PE

Whakamutunga

Ko te paipa PE100 te paerewa teitei rawa atu o te HDPE, e tautuhia ana e tōna kaha me tōna pakari. Mā te mārama ki ōna āhuatanga me te whakahaere i ōna herenga torutoru ka taea e koe te hanga hanganga pono, pumau hoki.

Mena kei te rapu koe i ngā paipa me ngā taputapu HDPE PE100 pono mō āu kaupapa, tēnā whakapā maiwhakapā maimō ngā taipitopito hua me te tautoko hangarau.
