Crosslinked polyethylene: tono me ngā āhuatanga

Polyethylene Ko te rauemi e whakamahia e te i roto i ngā ahumahi. Products i reira e whakamahia hoki i roto i te ora ia rā. polyethylene Common te mau tonu tana kaha ki runga ki te 130 nekehanga. Heoi, he mea e tika ana maha ki te whakamahi i tenei rauemi, me te i roto i ngā āhuatanga ake kino i te pāmahana nui, me te pēhanga, hei tauira i roto i te pūnaha whakawera me te wai wera.

Kua arahina tenei hiahia ki te rapu mō huarahi ki te whiwhi i te rauemi atu roa. hangarau kitea whiwhi polyethylene crosslinked, e kua he taimaha nui rāpoi rite whakaritea ki te rauemi tikanga, a ka kua pai ake ngā āhuatanga. Na roto i te hono matau te tukanga i ai hono nga rāpoi tika ki te hanganga o e hono i roto i te shirokoyacheistuyu mātiti e toru-ahu ripeka-hononga.

Tei runga i te pānga tono wehewehe matū me te crosslinking tinana. I roto i te take whakamutunga, irradiated te putorino (whakamahia polyethylene ripeka-hono te ki te hanga i ngā tūemi o raraunga) i te X-hihi mārō. Ko te tino hua tenei hangarau, a i roto i te meneti e taea te tiki e koe ki runga ki te 80 mita o rauemi.

He ngoikoretanga o te tikanga, ko e te polyethylene crosslinked he matotoru pāhiwihiwi o te okana. I roto i te roto o te tahuri te ōrau i raro o ngā rāpoi ngota pūhui, me i te waho, i runga i te anga ke, te rawa. Fakatatau ki ai, ngā āhuatanga rerekē me ngā hua i roto i te nuinga. Ko te hua ko te kāwai polyethylene crosslinked C (PEX).

A, no te te whakamahi i te tikanga matū mo te whakakapinga o te ngota hauwai i roto i te rāpoi ngota e whakamahia taonga silane motuhake. Fakatatau ki ai, crosslinked he silane polyethylene. I roto i te hanga o putorino tika i roto i te pati motuhake i nga taonga. taea tēnei ki te hanga tukanga crosslinking ōrite o nga papa i roto, me te waho o te taiepa okana i roto i te hohonu. hanga ana tēnei hangarau reira taea ki te farii i te putorino ki te ōrau nui o tukatuka, me te rauemi tohua PEX-B.

He he he tikanga o te tukatuka i te Radicals hauota polyethylene i tohua rauemi ahu PEX-D. Heoi, e kore te mea e hāngai ana tenei hangarau e tika ana ki te tōtika iti.

te mahi hoki peroxides ripeka-hono. I roto i tenei take, kei roto i te tukanga whakaputa te ranu o te hauwai me te polyethylene, ka i roto i te āhua whakarewa me raro whiwhi tiketike pāmahana polyethylene crosslinked PEX-A rōpū.

Pou rauemi (rōpū B, C) whakamahia mo te wai, me te whakawera, Heoi, i ratou e rave rahi fakangatangata e pā ana ki te taikaha me te hua te kōngohe.

He putorino i hanga o te rōpū polyethylene te te angitu tino, to ratou kaha rohirohi tiketike, anganga resistance, pūmautanga ahu, ngāwari, te manawanui ki te paorooro.

Heating PEX putorino e whānui whakamahia mō te whaiaro, ture, me te hanga ahumahi. Ki te to ratou awhina kawe Papa tahora whakamahana me te hanga i te pūnaha papa whakawera.
