Ko te pepa PP ātete-mura he pepa kirihou i hangaia ki te kapia PP, me ngā tāpiri mahi maha i tāpirihia mā te extrusion, te calendering, te whakamatao, te tapahi me ētahi atu tukanga. Ko te pepa PP ātete-mura he rauemi haurua-kiriata. He mārō ake i te PE, ā, he teitei ake te ira rewa. Nā te mea he tino pakarukaru te pāmahana homopolymer PP i runga ake i te 0C, he maha ngā rauemi PP arumoni he copolymers matapōkere me te ihirangi ethylene 1-4%, he copolymers poraka rānei he nui ake te ihirangi ethylene. He iti te pāmahana whakararuraru wera o ngā rauemi PP Copolymer (100°C), he iti te mārama, he iti te kanapa, he iti te pakari, engari he kaha te pānga. Nō reira, me pēhea te tautuhi i te kounga o te pepa PP ātete-mura?
1. Tirohia te kanapa o tōna mata. Ko te kanapa ngoikore he kirihou hangarua.
2. Tirohia tōna pakari. He tino pakari te pepa PP ātete ahi o te rauemi mata parakore, ā, ka taea te piko paku.
3. Tirohia te mata tapahi. Whai muri i te tapahi i te kirihou hangarua, ka kitea he maha ngā para o ngā tae rerekē.
4. Tirohia tōna mātotoru. Ko te mātotoru o te PP polypropylene he 0.92~0.93. He polypropylene ngā rauemi katoa e mānu ana i runga i te wai.
5. Ka whakamahanahia, ka whakarewahia te pepa PP ātete mura. Ka puta te paoa ina whakarewahia te kirihou hangarua.
6. Te tuku mārama, he ngoikore te tuku mārama o ngā kirihou hangarua.
7. He pakari, he kino rawa atu hoki te kirihou hangarua.
8. He matotoru te pepa PP ātete-mura, maka ki roto i te wai kia kite mēnā kei te mānu i runga i te wai, ko te nuinga o te wai hangarua ka totohu ki raro.
