Āhuatanga Mechanical
te tau mahani PP he crystallinity tiketike, me te hanganga auau, a ko te kupu kua āhuatanga hangarau pai. Heoi, i te pāmahana rūma, ka iti te pāmahana, he rawakore te kaha pānga e tika ana ki te nui rawa o te auautanga hanganga rāpoi. Ko te mahi atu tino o te putorino PP ko te ātete ki piko rohirohi, e mōhiotia ana te piripiri rau-taiepa.
Mahi Thermal
te rangi mahani PP he ātete wera pai, a taea te oneone te hua, me te oneone i te pāmahana o te 100 ° C teitei ranei, a kore e hauā i 150 ° C i raro i te huru o kahore ope waho. Ko te pāmahana embrittlement ko -35 ° C, puta embrittlement i raro -35 ° C, a kahore he rite pai rite polyethylene te ātete makariri.
Matū pūmautanga
He tino pai te pūmautanga matū o te tau mahani PP. Haunga te tauria e te waikawa pungatara kukū, me te kukū waikawa hauota, he reira kainga ki ngā atu tauhohenga matū. Heoi, taimaha rāpoi waiwaro tīmeka iti, waiwaro kakara me waiwaro chlorinated taea fakamolū te putorino PP. A, huamo, a kua pai ake hoki tona pūmautanga matū ki te hua o te crystallinity, na he pai hoki te hanga o ngā putorino matū me whare, he pai pānga anti-waikura PP putorino.
Mahi hiko
te PP tau mahani he pai nui-auau mahi mātao, a mai i whakauaua a reira absorbs wai, e kore te te mahi mātao pāngia e te haumākū. He he tamau uruhanga tiketike, me te taea te whakamahi ki te hanga hua mātao hiko wera rite pāmahana e whakatika. Kei reira hoki te ngaohiko wehenga tiketike, me te he e tika ana mō te whakamahi hei apatoko hiko. He ātete pai ki te ngaohiko me te ātete pewa, engari te mea hiko pateko tiketike, me te he ngāwari ki te tau ki te parahi.
Weather ātete
he tairongo ki te marama hihi katinga te tau mahani PP, me te tua o te konutea waikura, dilauryl thiodipropionate, waro pango rite ranei filler ma e taea te whakapai ake i tona resistance toulekeleká.
