DIN 30670-1he tukanga whakaputanga paparanga-toru e whakaputa ana i te polyethylene (3LPE) paninga i runga i te mata o te whakapiringa roa, whakarara rānei, me tengā paipa maitai kore honongahei tiaki i a rātou i te waikura.
Ka whakamahia nuitia i roto i ngā pūnaha paipa tanumia, i raro rānei i te wai mō te kawe i ngā wai, i ngā hau rānei.
Kia mōhio: Kua wehea te DIN 30670 kia rua ngā wāhanga i roto i te putanga hou o te tau 2024, i runga i te tukanga whakaputa, arā, ko te DIN 30670-1 e kapi ana i ngā paninga polyethylene kua whakapūkarahia, ā, ko te DIN 30670-2 e kapi ana i ngā momo kua whakakāhia me ngā momo kua rehuhia ki te mura.
E rua ngā momo e wehea ana i runga i te pāmahana hoahoa, arāmomo N me te momo S.
| Momo | Te pāmahana hoahoa (°C) |
| N | -20 ki te + 60 |
| S | -40 ki te + 80 |
meISO 21809-1e rite ana ki te akomanga A me te akomanga B, ia.
Paparanga tuatahi: Me whakamahi te paparanga kapia epoxy, me te paura kapia epoxy.
Paparanga piripiri tuarua, ka taea te pania ki te paura, ki te pania rānei ki te ipu whakarewa.
Paparanga tuatoru Paparanga polyethylene, tukanga whakaputa ngongo, tukanga whakaputa takai rānei.
Te Whakaputa Ngongo:
I tēnei tukanga, ka tukuna tika atu te rauemi polyethylene ki roto i tētahi āhua ngongo tonu, kātahi ka honoa ki te paipa maitai.
Ko tēnei tikanga e whakamahia ana mō ngā paipa iti te diameter, ā, ka whakarite kia ōrite, kia tonu hoki te paninga.
Te whakaputanga takai:
I tēnei tukanga, ka whakaputahia te polyethylene hei rīpene, kātahi ka takai ki te mata o te paipa rino.
He pai tēnei tikanga mō ngā paipa he whānui nui, he rahi rerekē rānei, ā, ka taea te paninga ngāwari ake ki ngā paipa uaua, rahi nui rānei.
I runga anō i ngā hiahia motuhake o te kaupapa, ka taea te tāpiri i tētahi atu paparanga tiaki ā-mīhini ki te 3LPE.
Ko ngā rauemi e whakamahia whānuitia ana koraima(tirohia te ISO 21809-5),kirihou whakakaha muka karāhe, moata sima rānei(tirohia te DN N 30340-1).
Hei whakarite i te kaha kutikuti pai, me whakararuraru, me pēhi rānei te mata o te polyethylene.
Mā tēnei momo maimoatanga ka whakapiki ake i te piri i waenga i te paparanga tiaki tāpiri me te paninga polyethylene.
Te Matotoru o te Paparanga Resin Epoxy
80um te iti rawa.
Matotoru o te Paparanga Piripiri
150um te iti rawa.
Matotoru Katoa o te Paninga
I runga i te diameter ingoa o te paipa maitai, ka rerekē te matotoru o te paparanga tiaki waikura.
Mō te matotoru katoa o te paparanga 3LPE, e toru ngā akomanga e wehea ana e te DIN 30670-1 hei whakatutuki i ngā whakaritenga hanga rerekē.n,v, me s.
Tau nMō ngā āhuatanga noa, he rawaka te matotoru o te taumata n.
Mō ngā paninga polyethylene, ko te matotoru o te 1 mm te mea matua hei ārai i te waikura, ko te matotoru e toe ana hei whakapakari i te kaha o te paparanga tiaki ki te kawe i ngā kawenga ā-pūkaha.
Taumata vMena ka piki ake te kawenga ā-ringa (te kawe waka, te rokiroki, te whakatakotoranga, te kounga motuhake, te pikinga o ngā whakaritenga), me whakanui ake te matotoru iti rawa o te paninga mā te 0.7 mm, arā, v = n + 0.7 mm.
Ngā tohuKa taea hoki te whakaae ki ngā matotoru paninga motuhake he nui ake i te v hei whakatutuki i ngā hiahia o tētahi kaupapa motuhake, ā, ko aua matotoru paninga kua whakaritea ka tapaina ko te Wāhanga s.
150mm ± 20mm, kaua te koki piko mō te matotoru o te paninga e neke ake i te 30°.
Me tango ngā paparanga epoxy me te piripiri kia 80 mm te iti rawa mai i te pito o te paipa. Me waiho te paparanga epoxy kia puta mai i te pito o te paipa kua pania ki te polyethylene kia kaua e iti iho i te 10 mm.
Hei whakatau i te roa, inehia mai i te mata pakiaka o te paipa ki te tīmatanga o te pito tapahi whakarara o te paparanga ārai waikura.
Ngā Hapa Whānui
Kāore anō kia tutuki ngā hapa iti me ngā pakaru ki te mata o te maitai.
Ngā kōhao i te paparanga o runga o te PE;
Ngā wāhi iti ake kāore i te kapi katoa;
Ngā whakaurunga me ngā mirumiru hau i te paparanga o runga;
Te piri o ngā matū ke;
Te pakū o te mata;
Ngā pakaru iti i roto i te paninga.
E whakaaetia ana kia whakatikahia ēnei whara iti, ā, kāore he rohe mō te wāhi ka taea te whakatika.
Ngā Hapa Nui
Ka tika tonu te pakaru o te paninga ki te mata o te paipa rino.
Kaua e neke atu i te 10 henimita tapawha te horahanga o ngā hapa takitahi hei whakatika. Ko te maha o ngā hapa e whakaaetia ana hei whakatika ko te 1 hapa mō ia mita 1 o te roa o te paipa. Ki te kore, me tuhi te paipa.
ISO 21809-1Mō ngā paninga polyethylene me te polypropylene e toru-paparanga kua whakapūtāhia ki waho (3LPE me te 3LPP) mō ngā paipa maitai e whakamahia ana i roto i ngā pūnaha tuku i roto i te umanga hinu me te hau.
CSA Z245.21: E tohu ana i ngā paninga polyethylene ā-waho ārai-waikura mō ngā paipa maitai e whakamahia ana i roto i ngā pūnaha kawe.
AWWA C215He paninga polyethylene ā-waho ārai-waikura e tika ana mō ngā paipa tuku wai. Ahakoa e whakamahia ana mō ngā pūnaha kawe wai, he rite tonu ki te DIN 30670 e pā ana ki ngā rauemi me te hangarau tono.
Kei te tino hiahia mātou ki te mahi tahi me koe ki te whakarato i ngā paipa rino kounga teitei me ngā otinga paninga ārai-waikura mō āu kaupapa. Tena koa whakapā mai ki a mātou mō ētahi atu taipitopito hua, ka koa mātou ki te āwhina i a koe ki te kimi i te kōwhiringa paipa rino pai rawa atu mō ō hiahia!
