Nkhani

1. Kusiyana kwa momwe ntchito ikuyendera.
Mulingo wogwiritsira ntchito mbale za PE: umagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makina, makampani opanga mankhwala, magetsi, zovala, ma CD, chakudya ndi ntchito zina. Umagwiritsidwa ntchito kwambiri poyendetsa gasi, kupereka madzi, zimbudzi, ulimi wothirira, migodi, mayendedwe olimba a tinthu tating'onoting'ono, komanso mafuta, makampani opanga mankhwala ndi ma positi ndi mauthenga, makamaka poyendetsa gasi.

Mulingo wogwiritsira ntchito mbale ya Pp: zida zotsutsana ndi asidi ndi alkali, zida zoteteza chilengedwe, madzi otayira, zida zotulutsira mpweya wotayira, nsanja yotsukira, chipinda choyera, fakitale ya semiconductor ndi zida zina zokhudzana nazo zamafakitale, ndiye chisankho choyamba popanga thanki yamadzi ya pulasitiki, mbale yokhuthala ya pp imagwiritsidwa ntchito kwambiri mu mbale yobowola, mbale yobowola ndi zina zotero.
2. Kusiyana kwa makhalidwe.
Mbale ya PE ndi yofewa, ili ndi kulimba kwina, kukana kugwedezeka ndipo magwiridwe antchito a buffer ndi abwino, magwiridwe antchito a mbale yowumbidwa ndi abwino; kuuma kwa bolodi la PP ndi kwakukulu, mawonekedwe a makina si abwino, kulimba kochepa, komanso kutsika pang'ono kwa buffer.
3. Kusiyana kwa zinthu.
Bolodi la PP, lomwe limadziwikanso kuti bolodi la polypropylene (PP), ndi chinthu chopangidwa ndi theka-crystalline. Ndi lolimba kuposa PE ndipo lili ndi malo osungunuka kwambiri. Pepala la PE ndi crystallinity yapamwamba, non-polar thermoplastic resin. Mawonekedwe a HDPE yoyambirira ndi oyera ngati mkaka, okhala ndi kuwala pang'ono m'gawo lopyapyala.
