ISO 21809-1e pā ana ki ngā pūnaha paipa tanumia, ruku rānei i roto i te umanga hinu me te hau, ā, e tohu ana i ngā whakaritenga mō ngā paninga tiaki waikura o waho.3LPE me 3LPPmōngā paipa maitai kua whakarewaina, kua tuituia hoki.
E toru ngā momo rauemi mata, i runga i te momo rauemi mata:
A: LDPE (polyethylene iti-kiato);
B: MDPE/HDPE (polyethylene kiato-waenga)/(polyethylene kiato-teitei);
C: PP (Poroporoperene).
Kei te wāhanga iti e whai ake nei ngā whakaritenga mō te matotorutanga o ia rauemi e whakamāramahia ana i roto i ngā taipitopito mō ngā whakaritenga mō ngā rauemi mata e toru.
| Akomanga paninga | Rauemi paparanga o runga | Te pāmahana hoahoa (°C) |
| A | LDPE | -20 ki te + 60 |
| B | MDPE/HDPE | -40 ki te + 80 |
| C | PP | -20 ki te + 110 |
Me toru ngā paparanga o te pūnaha paninga:
paparanga tuatahi: epoxy (wai, paura rānei);
paparanga tuarua: piripiri;
Paparanga tuatoru: Paparanga o runga PE/PP i pania mā te extrusion.
Ki te hiahiatia, ka taea te pania he paninga taratara hei whakanui ake i te ātete ki te paheke. Ina koa ko ngā wāhi e hiahiatia ana he pai ake te pupuri me te whakaiti i te tūponotanga o te paheke.
Te Matotoru o te Paparanga Resin Epoxy
Mōrahi 400 um
Iti: wai epoxу: iti 50um; FBE: iti125um.
Matotoru o te Paparanga Piripiri
150um te iti rawa i runga i te tinana paipa
Matotoru Katoa o te Paninga
Ka rerekē te matotoru o te paparanga ārai-waikura i runga i te kawenga o te papa me te taumaha o te paipa,me te whiriwhiri i te matotoru o te paparanga ārai-waikura kia rite ki ngā āhuatanga hanga, te tikanga whakatakotoranga paipa, ngā āhuatanga whakamahi, me te rahi o te paipa.
Ko te Pm te taumaha o te paipa maitai mō ia mita.
ka taea te pātai mā te tirotiro i ngā mea e tika anatepu taumaha o te paerewa paipa maitai, mā te tātai rānei:
Pm=(DT)×T×0.02466
Ko D te diameter o waho kua tohua, e whakaaturia ana i roto i te mm;
Ko T te matotoru o te pakitara kua tohua, e whakaaturia ana i roto i te mm;
Ngā Whakaritenga mō te Rauemi Epoxy
Ngā Whakaritenga mō te Rauemi Piripiri
Ngā Whakaritenga mō te Paparanga Runga PE/PP
Ka taea te wehewehe i te tukanga ārai-waikura kia:
1. Te whakarite i te mata;
2. Te paninga paninga
3. Whakamatao
4. Te Whakaiti
5. Te Tohu
6. Te tirotiro i ngā hua kua oti
1. Te Whakarite i te Mata
Kei roto i ngā paerewa SSPC me NACE ngā whakaritenga ōrite, ā, koinei te hononga whānui:
| ISO 8501-1 | NACE | SSPC-SP | Whakatūnga |
| Sa 2.5 | 2 | 10 | Te horoinga whakarewa tata-mā |
| Sa 3 | 1 | 5 | Te horoinga pahūtanga whakarewa mā |
Kia mōhio mai, kāore te pānga o te Sa 2.5 i te pumau i runga i te taumata waikura o te paipa maitai, e whakarōpūtia ana ko A, B, C, me D, e rite ana ki ngā pānga e 4.
2. Te Whakamahinga Paninga
Me whakarite kia tika te pāmahana whakamahana me te tere o te raina o te paipa maitai i te wā e pania ana kia pakari rawa ai te paninga paura, kia piri tonu ai te paninga, kia whakahaere hoki i te matotoru o te paninga.
Ko te matotoru o te paparanga tiaki waikura e pā ana hoki ki ngā tawhā o te taputapu paninga.
3. Whakamatao
Me whakamatao te paninga kua pania ki tētahi pāmahana e kore ai e pāngia ngā kino i te wā whakaoti me te tirotiro whakamutunga.
Ko te tikanga, kāore te pāmahana whakamatao o te 3LPE e neke ake i te 60℃, ā, ka paku teitei ake te pāmahana whakamatao o te 3LPP.
4. Te Whakaiti
Me tango he paninga roa i ngā pito e rua o te paipa, ā, kaua te paparanga ārai waikura e whakapikohia ki te koki neke atu i te 30° hei ārai i te kino pea o te paninga ārai waikura i te wā e whakarewahia ana.
5. Te Tohu
Te whakatutuki i ngā paerewa me ngā whakaritenga a te kiritaki.
Me tāia, me peita rānei ēnei tohu kia mārama ai ngā reta, ā, kia kore ai e memeha.
6. Tirotiro Hua Kua Oti
He tirotiro whānui o ngā paipa ārai-waikura kua oti te hanga kia tutuki ai ngā whakaritenga o te ISO 21809-1.
Ngā tono 3LPE
He tino ātete matū ngā paninga 3LPE, he tino pai te tiaki ā-mīhini me te roa o te ora, ā, he iti hoki ngā utu tiaki.
He pai mō ngā paipa tanumia, mō raro i te wai rānei, e hiahia ana ki te ātete nui ki te waikura me te tiaki ā-mīhini i roto i ngā taiao oneone me te wai.
E whakamahia whānuitia ana i roto i ngā pūnaha paipa mō te kawe hinu, hau, me te wai.
Ngā Taupānga 3LPP
He nui ake te ātete o ngā paninga 3LPP ki te pāmahana me te pumau matū i te polyethylene. Heoi, ka pakarukaru pea i ngā pāmahana iti.
He pai mō ngā pāmahana teitei ake me ngā taiao uaua ake, pērā i te hono i ngā paipa ki ngā wāhi wera ake, ki te taha rānei o ngā wheketere tukatuka matū.
He mea whakamahi noa i roto i ngā pūnaha paipa hinu me te hau e hiahiatia ana te mahi pāmahana teitei.
