Nā ngā pereti polyethylene tēnei nā te mea i ētahi wā ka āraia e ngā mekameka ngota ngā tioata whakaahua, ka waiho he rohe nui kore-āhua i roto i te koiora ngota, ka taea e ngā pereti polyethylene te mimiti i te nui o te kaha nekeneke pānga. E ai ki te tohutoro, ka whakamahia te tikanga astm-D256 hei whakatau i te pānga o te uara kaha pēhi kirihou. E ai ki te whakataurite, ka taea te wehewehe i te kaha pēhi o te papa polyethylene ki te polycarbonate, e mōhiotia ana te polycarbonate mō tōna ātete pānga, ā, ka taea te whakamahi hei hua rapa whānui.
He tino iti te ātete ki te waku o te pereti polyethylene. He pai ake te ātete ki te kakahu o te papa polyethylene, he iti te ātete ki te waku, ā, he pai te mākū-ā-roto. Koinei te rauemi mata o te pū, te roera me te pū. Mā te whiriwhiri i te papa polyethylene hei takirua waku, ehara i te mea ka taea anake te whakapai ake i te roa o te mahi a ngā whare, engari ka taea hoki te penapena rauemi.
He pai te ātete matū o te papa polyethylene. He pai ake te ātete matū o te papa polyethylene. Haunga te waikawa hauota kukū me te waikawa whanariki, ehara i te mea ngāwari te whakairo i te papa polyethylene ki roto i tētahi otinga kawakore, waikawa rānei. Ka taea te whakamahi hei waikawa hauwaiwai waimeha i te 80℃, i roto i te konutai cyanide & LT; Waikawa hauwaiwai < 75% maeneene, ka taea hoki te whakamahi me te wai me te horoi wai. E mōhio ana te katoa, he tino ngāwari te pupuhi o te papa polyethylene i roto i ngā hauwaiwai aliphatic, i ngā halogenates rānei (ina koa i te pāmahana tiketike tonu), nō reira me aro nui ki tōna whakamahinga.
Whakapai ake i te ātete kakahu o te papa polyethylene. Ko te ātete kakahu teitei tētahi o ngā āhuatanga whakamīharo, he nui ngā kaupapa e whakamahi ana i te papa polyethylene. I tēnei wā, he pai te ātete kakahu o ngā papa polyethylene kirihou katoa, ā, he maha ngā rauemi whakarewa kāore i te rite te auau ki mua. Mā te whakapai ake i te taumaha ngota o te polyethylene pēhanga teitei, ka pai ake hoki te ātete kakahu o tēnei momo rauemi. Ātete pānga o te papa polyethylene. E pā ana te kaha pēhi o te pereti polyethylene ki tōna taumaha ngota. Ina iti iho te taumaha ngota whanaunga i te 2 miriona, ka piki ake te kaha pēhi pānga o te pereti polyethylene me te pikinga o te taumaha ngota whanaunga, ā, ko te uara teitei ake ko te 2 miriona. I tēnei wā, ka heke te kaha pēhi pānga me te pikinga o te taumaha ngota whanaunga.
