Me Pēhea Te Whakanui a te Orientihanga Mokowhiti i te Mahi a PVC

Ina tāwhai mātou i ngā paraihe i ngā tāwhai e rua ake i te wā o te hanga, ka whakarāranga pea ēnei molekī tino roa ki te pātata anō hoki ki te pātata o te matēria, ka waihangatia he rōpū hāngai tino kaha ake. I te wā o te tāhuna, ina pāwhara te tāwhai umanga ki te 60%, ka āwhina tēnei ki te whakarāranga ake i ngā kirimaumu within the material better. E ai ki ngā rangahau a Faygoplas i te 2024, ko te whakapai ake i te rōpū e whakapai ake ana i te matēria kia tino pakari ake ki ngā mea pērā i te toki mai i roto hoki i ngā kaha e toki mai ana i waho. Ko te mea hira kua pērā nei te huringa o te rōpū e iti ana i ngā wāhi e hui haere ai te toki. Nō reira, ko ēnei pīpoi PVC-O motuhake he 35% te iti ake o te tūponotanga o te popoinga o te wā ki te upoko ki ngā putanga PVC-M noa e kore e hiahiatia tēnei tikanga whakapakari atu.

He aha te take e tino pai ake ai te PVC-O i ngā pīpoi PVC-U me te PVC-M tūmatanui

Ko te PVC-O e kuhu ana i ngā āhuatanga pai rawa atu o ēnei ao e rua, arā ko te pūkaha o te PVC-U me te māmā o te PVC-M ki te tīpapa i te wāhi pai rawa, kei te 3,200 MPa te modulus. Ko te PVC-U noa he mea pakaru pea ina piki te hōmiro mōment, engari he rerekē te hanganga āhuahua o te PVC-O nā reira ka whakauru i te takirua, ka iti ake ngā pakanga pea ki te kotahi tuatoru e ai ki ngā whakamātautau mara. I whakamātauria e ngā toa ki a PVC4Pipes, ā, i kitea ai ko te PVC-O e taea ana te tino whakatōnga i ngā pikinga hōmiro, anei te tokomaha pea o ngā pikinga e taea e te PVC-M i mua i te pakaru.
