Ko ngā hononga miihini o tō pūnaha paipa te mea tuatahi e pakaru ana. Ka taea e te turuturu o te gasket, e te nati kōpeketanga rānei te whakararu i te pūnaha, te utu nui o ngā whakatikatika, me te wā e kore ai e mahi.

He hononga kirihou wera te hononga honohono (pērā i te HDPE, PP-R rānei) e honoa ana ki tētahi paipa mā te whakarewa wera. Ka whakarewahia te taha waho o te paipa me te taha roto o te hononga e tētahi taputapu motuhake, kātahi ka panaia ngātahitia hei hanga i tētahi wahi kotahi, pumau, ātete turuturu.

E maumahara ana ahau ki taku kōrero ki tētahi kiritaki e whakahaere ana i tētahi kaupapa whakamakuku nui. I raru tonu ia i ngā turuturu mai i ngā taputapu miihini tuku iho nā te nekehanga o te whenua me ngā huringa pēhanga wai. I taku whakamōhiotanga i a ia ki te ariā ohononga hononga, he mea whakarerekē i te kēmu. Nā te whakaaro ka taea e te hononga te kaha rite, te kaha ake rānei i te paipa tonu i whakatau i tana raruraru pono nui rawa atu. He hangarau māmā noa iho, engari ina mārama koe ki tana mahi, ka kite koe i ōna painga nui. Me keri tātou ki roto i ngā taipitopito.

He aha tonu te mea i hangaia ai te hononga PE?

Ka kite koe i te kupu "PE" i runga i te hononga engari kāore koe e mōhio he aha te tikanga mō te kaha. Mēnā ka whiriwhiria he hononga i hangaia mai i te momo kirihou hē, ka raru pea i raro i te pēhanga.

He mea hanga te hononga PE mai i te polyethylene. Mō ngā paipa pēhanga, he HDPE te nuinga o te wā, he rauemi pakari, ngāwari, ātete ki ngā matū, he tino pai mō ngā tono uaua pēnei i te tohatoha wai me te hau.

He whānau kirihou te polyethylene, engari kāore i te rite te hanganga o ngā momo katoa. Ko te kī ko te mātotoru. Ka nui ake te mātotoru, ka kaha ake, ka pakari ake hoki te rauemi. Mō ngā hononga honohono e whakamahia ana i roto i ngā paipa wai, i ngā paipa ahumahi rānei, ka whakamahia e mātouHDPE, e kiia ana ko PE100. He tino teitei te taumaha ngota o tēnei momo, ā, he tino ātete ki te pēhanga, ki ngā pānga, me ngā matū. Ko te rauemi kotahi tēnei e whakamahia ana mō ngā paipa tonu. Mā tēnei ka whakarite kia honoa e koe ngā rauemi e rua rite tonu ina honoa e koe he hononga Pntek PE ki tētahi paipa PE. Ko tēnei hototahi te pūtake mō te hanga i tētahi whakarewanga tino pai, kotahi te āhua, ka roa mō ngā tekau tau me te kore e pirau. He rauemi i hangaia mō te haumarutanga roa.

Ngā Momo Polyethylene Noa

He aha ngā momo paipa ka taea te hono mā te hononga PE?

He taputapu hanumi tāu, engari kāore koe i te tino mōhio ko ēhea momo paipa kirihou ka whakamahia. Mēnā ka ngana koe ki te hanumi i ngā rauemi kāore e hototahi, ka kore rawa e honoa.

Ka whakamahia te hanumi PE hei hono i ngā rauemi kirihou rite. He mea hanga motuhake mō ngā paipa polyethylene (PE) pērā i te HDPE me te MDPE, tae atu ki ngā paipa polypropylene (PP-R). Kāore e taea te hono i ngā kirihou rerekē pērā i te PE ki te PVC.

Ko te mātāpono owhakarewa honohonohe māmā noa iho: kei te whakarewa koe, kei te hanga anō hoki i te kirihou. Kia mahi ai tēnei, me rite te hanganga matū me te pāmahana rewa o ngā wāhanga e rua e honoa ana e koe. Koia te take ka taea anake te whakakotahi i te "rite ki te rite." Ko te whakamahinga tino noa ko te whakakotahiPaipa HDPEki ngā hononga HDPE mō ngā pūnaha e hiahia ana kia tino pono. Kei roto i ēnei ko ngā puna wai ā-rohe kua tanumia ki raro i te whenua, ngā raina matū ahumahi pēhanga teitei, me ngā whatunga tohatoha hau māori. Ko te tukanga whakakotahitanga o te kōhao kotahi anō te tikanga paerewa mō te hono i ngā paipa PP-R, he mea rongonui mō ngā putorino wai wera me te wai matao i roto i ngā whare. Ko te mea nui ko te whakakotahitanga ka hangaia he pūnaha maeneene, engari mēnā he tino ōrite te paipa me ngā rauemi whakauru.

Me pēhea te hono i ngā paipa me ngā hononga HDPE?

Tērā pea he uaua te tukanga whakarewa honohono. Kotahi te nekehanga hē, ka ngoikore pea te hononga ka pakaru i muri mai, ka whakangaro i te whakapono ki tō mahi tāutanga.

Hei whakakotahi i te HDPE, ka whakamahanahia te mata o waho o te paipa me te mata o roto o te hononga ki tētahi taputapu mō tētahi wā kua whakaritea. Kātahi ka pēhia ngātahitia, ka puritia kia mātao rā anō. Mā tēnei ka hangaia he hononga tuturu, he hononga whakarewa.

He tino māmā te tukanga engari he tika, ki te whai koe i ngā kaupae e whai ake nei.

1. Te whakarite:Tuatahi, tapahia te pito o te paipa kia tapawhā tika. Kātahi ka horoia te pito o te paipa me te roto o te putanga whakauru hei tango i te paru, i te hinu rānei.
2. Whakamahana:He urutau whakamahana kei te taputapu honohono hononga mō ngā rahi paipa rerekē. Panahia te paipa ki tētahi taha, me te hononga ki tētahi taha i te wā kotahi. He mea nui te wā whakamahana, ā, e whakawhirinaki ana ki te whānui o te paipa.
3. Te Hononga:Kia pau te wā whakamahana, tangohia wawetia ngā wāhanga e rua mai i te taputapu. Pēhia tonutia te paipa ki roto i te putanga o te hononga kia mutu rā anō. Kaua e takahuri.
4. Whakamatao:Puritia te hononga kia kaua e neke mō te wā whakamatao kua tohua. Mā tēnei ka taea te totoka o te kirihou rewa hei wahi kotahi, kaha.

He mea nui te whai i ngā wā whakamahana me te whakamatao tika mō te hanga hononga pono.

He aha i kaha ake ai te hononga honohono i te hononga miihini?

Ka whakamahia e koe ngā hononga miihini nā te mea he ngāwari ki te tāuta. Engari e mōhio ana koe he wāhi pakaru pea ia gasket me ia miro ka wetekina i roto i te wā.

He kaha ake te hononga honohono nā te mea ka whakakorea katoatia te hononga. Ka noho te paipa me te hononga hei wahi kirihou totoka kotahi. Kāore he hiri hei whakaiti, he pūtu rānei hei wetewete i tēnei hononga kotahi, ā, ka kaha ake i te paipa tonu.

Ka honoa ngā wāhanga e rua e te hononga miihini, engari ka whakakotahihia e te whakarewa hanumi. Whakaarohia he mekameka whakarewa; ko tōna kaha anake ko tōna hononga ngoikore rawa. I roto i te paipa me ngā hononga miihini, ko ngā hononga ngā hononga ngoikore. Ka whakawhirinaki rātou ki te pēhanga o te gasket rapa, ki te waku rānei o ngā miro hei hanga hiri. Ka pāngia ēnei e te wiri, ngā huringa pāmahana, me te nekehanga whenua. Kāore he ngoikoretanga o te whakarewa hanumi. Ko te tikanga o te tukanga whakarewa me te hanga anō i te HDPE ko te horahanga o te hononga ka huri hei poraka kirihou totoka kāore he hononga. Ina whakahaerehia e mātou ngā whakamātautau pēhanga pahū i roto i tā mātou taiwhanga, ka pakaru tonu te pakitara paipa i mua i te hononga hanumi. Koia te take mō ngā tono tino nui, kore-tūtaki e tanumia ana ki raro i te whenua, e whakatakotoria ana rānei ki roto i te raima, ko te whakarewa te kōwhiringa pono anake.

Hononga Whakakotahi me ngā Hononga Ā-Mīhini

Whakamutunga

Mā te whakakotahitanga o te pūwero ka hangaia he hononga pai rawa atu mā te whakarewa i te paipa me te whakauru ki roto i te wahi kotahi. Mā tēnei ka whakakorea ngā pūwāhi turuturu, ka waiho hei tikanga tino pono mō ngā pūnaha PE me PP-R.
