Te Pānga o te Tāpiri CPE ki te PVC

Te Pānga o te Tāpiri CPE ki te PVC

1, E toru ngā āhuatanga matua e pā ana ki te mahi a te CPE
Tuatahi, koinei te momo CPE e whakamahia ana. He nui te matotoru me te kaha kume o te CPE i puta mai i te polyethylene taumaha ngota teitei, engari he iti te piri i waenga i tēnei CPE me te kapia PVC. He iti te matotoru me te kaha kume o te CPE i puta mai i te polyethylene taumaha ngota iti, ā, he pai te ātete wera o te CPE i puta mai i te polyethylene kiato teitei.
Tuarua, ko te rahi o ngā matūriki o te rauemi mata. Ina iti rawa te rahi o te matūriki, ka ngāwari te hanga i te tiēre, i te CPE pūpū rānei, ā, ina nui rawa te rahi o te matūriki, kāore i te ōrite te tohatoha o te haukini.
Ko te taumata anō o te whakapūkara CPE. Ina iti iho te ihirangi chlorine i te 25%, he ngoikore te hototahi ki te PVC, ā, kāore e taea te whakamahi hei whakarerekē; Ina nui ake te ihirangi chlorine i te 40%, he pai te hototahi ki te PVC, ā, ka taea te whakamahi hei plasticizer totoka, kāore e pai hei whakarerekē pānga; He pai te ngāwari me te hototahi o te CPE me te ihirangi chlorine o te 36-38% ki te PVC, ā, he whānui te whakamahinga hei whakarerekē pānga mō te PVC. I tēnei wā, ko te CPE me te ihirangi chlorine o te 35% te mea e whakamahia whānuitia ana. He iti te tioata me te pāmahana whakawhiti karāhe o te CPE me te ihirangi chlorine o te 35%, he pai te ngāwari o te rapa, ā, he pai te hototahi ki te PVC. He whānui te whakamahinga hei whakarerekē pānga mō ngā hua mārō PVC.
2. Te Pānga o te Tāpiri CPE ki te PVC
Ina iti iho i te 10 meneti te nui o te tāpiri, ka tere te piki o te kaha pānga o te PVC me te tāpiri o te CPE, engari mā te whakanui ake i te nui o te tāpiri o te CPE ka iti te whakapainga o te kaha pānga o te PVC. Nō reira, hei ātete pānga, ko te nui o te CPE e tika ana kia tāpirihia he 8-10 wāhanga. I te pikinga o te CPE, ka heke tonu te kaha kume o ngā ranunga PVC, i te mea ka piki ake te roa i te wā whati. Mena ka whakaatuhia te pakari hei hua o te kaha kume me te roa i te wā whati, he mārama ka tino piki ake te pakari o te PVC me te pikinga o te tāpiri CPE.
