Te whiriwhiri i te tikatakirere pōro kirihou PPRHe mea nui tēnei hei whakarite i te whakahaere pai o te wai. Ehara i te mea ka whakarei ake i te mahi anake te takirere kua whiriwhiria pai, engari ka whakaitihia hoki ngā raruraru tiaki. Ahakoa mō te whakamahinga kāinga, mō te whakamahinga ahumahi rānei, ka roa, ka whai hua hoki tēnei wāhanga maha-whakamahinga, ā, he haumitanga atamai tēnei mō te angitu mō te wā roa.
Ngā Whakaaro Matua
- Kōwhiringā takirere pōro kirihou PPR kahakia roa te whakamahinga. Tirohia mēnā he pai ake te mahi a ngā takirere i hangaia ki te rauemi polypropylene pakari.
- Kia tika te rahi, te pēhanga, me te pāmahana mō tō pūnaha. Mā tēnei ka ārai i ngā turuturu, ā, ka pai tonu te mahi a ngā mea katoa.
- Hokona he takirere pōro kirihou PPR hei penapena moni i te roanga o te wā. He iti noa te tiaki e hiahiatia ana, ā, he iti ake te hiko e whakamahia ana, ka whakaiti i ngā utu whakatika me te hiko.
Te Mārama ki ngā Takirere Pōro Kirihou PPR
He aha ngā takirere pōro kirihou PPR?
Ko te takirere pōro kirihou PPR he momo takirere i hangaia mai i te polypropylene random copolymer (momo 3). He mea hanga hei whakahaere i te rere o ngā wai i roto i ngā pūnaha paipa. Ka whakamahia e te takirere he pōro hurihuri me te kōhao i waenganui hei tuku, hei aukati rānei i te rerenga o te wai. Nā tēnei tikanga māmā engari whai hua ka waiho hei whiringa rongonui mō ngā tono kāinga, arumoni, me ngā tono ahumahi.
Kei te wātea ēnei takirere i ngā rahi rerekē, mai i te 20mm ki te 110mm te nuinga. He mea hanga ēnei hei whakahaere i ngā pēhanga tae atu ki te 25 pae me ngā pāmahana tae atu ki te 95℃. Mā te tutuki i ngā paerewa pērā i te DIN8077/8078 Tiamana me te ISO 15874 ka noho pono, ka noho haumaru hoki. Anei tētahi tirohanga poto mō ā rātou whakatakotoranga hangarau:
| Whakatakotoranga | Ngā Taipitopito |
|---|---|
| Te Hanganga o ngā Rauemi | Ko te kōporemu matapōkere o te polypropylene (momo 3) |
| Awhe Rahi | 20mm ki te 110mm |

Ngā Painga o ngā Takirere Pōro Kirihou PPR i roto i te Whakahaere Wai
He maha ngā painga o ngā takirere poi kirihou PPR e pai ai mō te whakahaere wai. Tuatahi, he māmā, e māmā ai te tāutanga, e whakaiti ana hoki i ngā utu mahi. Tuarua, ko te ātete ki te waikura ka roa te mau, ahakoa i roto i ngā taiao uaua. Kāore i rite ki ngā takirere whakarewa, kāore e tauine, ka mau tonu te mahi pumau i roto i te wā.
Ko tētahi atu painga matua ko te tino pai o te whakamarumaru wera. He 0.21w/mk noa iho te kawe wera, ā, he tino penapena pūngao. E tutuki ana hoki i a rātou ngā paerewa akuaku, ā, he haumaru mō ngā pūnaha wai inu. Ahakoa e whakamahia ana i roto i ngā paipa wai wera, wai matao rānei, ka tukuna e ēnei takirere he mahi pono mō ngā tekau tau.
Ngā Take Matua mō te Kōwhiri i tētahi Takirere Pōro Kirihou PPR
Te pakari me te kounga o ngā rauemi
I te wā e whiriwhiri ana i tētahi takirere pōro kirihou PPR,me noho te pakari ki rungao tō rārangi arowhai. Ko te roa o te ora o te takirere e whakawhirinaki ana ki te kounga o ōna rauemi. Mā te polypropylene kounga teitei (momo 3) ka taea e te takirere te tu atu ki te pakaru me te haehae i roto i te wā. Ka ātete tēnei rauemi ki te waikura, ā, he mea pai mō ngā tono kāinga me ngā tono ahumahi.
Hei tāpiritanga, he mea nui te hanganga o te takirere ki tōna pakari. Rapua ngā takirere he hoahoa whakapakari ka taea te tu atu i ngā pēhanga me ngā pāmahana teitei me te kore e pakaru, e whakapē rānei. Ka taea e te takirere poi kirihou PPR pai te roa mō ngā tekau tau, ka whakaiti i te hiahia mō ngā whakakapinga auau.
Tohutohu:Me tirotiro tonu mēnā e tutuki ana ngā paerewa ahumahi pēnei i te DIN8077/8078 me te ISO 15874. Mā ēnei tiwhikete ka oati te tutuki o te takirere i ngā whakaritenga kounga me te haumaru tino pakari.
Hototahi ki te Rahi, te Pēhanga, me te Mahana
He mea nui te whiriwhiri i te rahi tika me te whakarite kia hototahi ki ngā whakaritenga pēhanga me te pāmahana o tō pūnaha. He maha ngā rahi o ngā takirere pōro kirihou PPR, mai i te 20mm ki te 110mm te nuinga. Mā te whiriwhiri i te rahi tika ka tika te taunga, ā, ka ārai i ngā turuturu.
Ko ngā whakatauranga pēhanga tētahi atu mea nui. Ka taea e te nuinga o ngā takirere pōro kirihou PPR te whakahaere i ngā pēhanga tae atu ki te 25 pae, ā, he pai mō ngā momo mahi maha. Heoi anō, me manatoko tonu te whakatauranga pēhanga kia rite ki ngā hiahia o tō pūnaha.
He mea nui anō hoki te hototahitanga o te pāmahana. Kua hangaia ēnei takirere kia mahi i roto i ngā taiao he teitei ake te pāmahana ki te 95℃. Nā tēnei ka tino pai mō ngā pūnaha wai wera, ngā tono whakamahana, tae atu ki ngā paipa matū.
Tuhipoka:Tirohia anō ngā āhuatanga o tō pūnaha paipa i mua i te hoko i tētahi takirere. Mā tēnei ka pai te whakaurunga me te mahi tino pai.
Te Whai Hua o te Utu mō te Wā Roa
Mā te haumi ki tētahi takirere poi kirihou PPR kounga teitei ka taea e koe te penapena moni mō te wā roa. Ahakoa he paku teitei ake te utu tīmatanga i ētahi atu kōwhiringa, he nui ake ngā painga i te utu. He iti noa te tiaki e hiahiatia ana mō ēnei takirere, ā, ka whakaitihia ngā utu whakatika i te roanga o te wā.
Ko tōna whai huatanga pūngao tētahi atu painga penapena utu. Nā te pai o ngā āhuatanga whakamahana wera, ka āwhina ngā takirere poi kirihou PPR ki te pupuri i te pāmahana ōrite, ka whakaiti i te whakapaunga pūngao. Hei tāpiri, ko te roa o te wā mahi—e neke atu ana i te 50 tau—ko te tikanga he iti ake ngā whakakapinga me te iti ake o ngā utu katoa.
Mā te whiriwhiri i tētahi takirere pakari, whai hua hoki, ehara i te mea ko te penapena moni anake tāu e mahi ana. Kei te haumi anō hoki koe ki tētahi otinga pono ka tutuki i ō hiahia mō ngā tekau tau.
