Nkhani

1. Kusiyana kwa ntchito.
Mulingo wogwiritsa ntchitoPE pepala: amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makina, makampani opanga mankhwala, magetsi, zovala, kulongedza, chakudya ndi ntchito zina. Amagwiritsidwa ntchito kwambiri pa kayendedwe ka gasi, madzi, kutulutsa zimbudzi, ulimi wothirira, kayendedwe kabwino ka tinthu kolimba mumigodi, komanso malo amafuta, makampani opanga mankhwala, positi ndi matelefoni, etc., makamaka pamayendedwe amafuta.
Kukula kwa mbale ya PP: zida zolimbana ndi asidi komanso zamchere, zida zoteteza chilengedwe, zida zotayira madzi otayira ndi gasi, nsanja yotsuka, chipinda chopanda fumbi, zida za fakitale ya semiconductor ndi mafakitale ogwirizana nawo, komanso zinthu zomwe amakonda kupanga thanki yamadzi yapulasitiki. Panthawi imeneyi, PP wandiweyani mbale chimagwiritsidwa ntchito kupondaponda mbale, nkhonya PAD, etc.
2. Kusiyana kwa makhalidwe.
PE board ndi yofewa ndipo imakhala ndi kulimba kwina, ndipo kukana kwake komanso kuwongolera kumakhala bwinoko, komwe gulu lopangidwa limakhala ndi magwiridwe antchito abwino; PP board ili ndi kuuma kwakukulu, kusachita bwino kwamakina, kulimba kotsika komanso kukana kukhudzidwa.
3. Kusiyana kwa zipangizo.
PP mbale, amatchedwanso polypropylene (PP) mbale, ndi theka-crystalline chuma. Ndizovuta kuposa PE ndipo ili ndi malo osungunuka kwambiri. PE pepala ndi mtundu wa thermoplastic utomoni ndi mkulu crystallinity ndi sanali polarity. Maonekedwe a HDPE yoyambirira ndi yoyera yamkaka, ndipo imawonekera pang'onopang'ono m'gawo lopyapyala.
