1, kusiyana kwa momwe ntchito ikuyendera.
Mulingo wogwiritsira ntchitoPepala la PE: imagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, makina, makampani opanga mankhwala, magetsi, zovala, ma CD, chakudya ndi mafakitale ena. Imagwiritsidwa ntchito kwambiri poyendetsa gasi, kupereka madzi, kutulutsa zinyalala, ulimi wothirira, migodi yonyamula tinthu tating'onoting'ono tating'onoting'ono, mafuta, makampani opanga mankhwala, positi ndi mauthenga ndi madera ena, makamaka poyendetsa gasi.

Kuchuluka kwa kugwiritsa ntchitopepala la pp: zida zopewera asidi ndi alkali, zida zoteteza chilengedwe, madzi otayira, zida zotulutsira mpweya wotayira, nsanja yotsuka, chipinda choyera, zida zamafakitale a semiconductor ndi mafakitale ena ofanana, komanso ndi chinthu chomwe chimakonda kwambiri popanga matanki amadzi apulasitiki, omwe mapepala okhuthala a PP amagwiritsidwa ntchito kwambiri. Amagwiritsidwa ntchito poponda mbale, kuponda mbale yobwerera, ndi zina zotero.

2. Kusiyana kwa makhalidwe.

Bolodi la PEndi yofewa pang'ono, ili ndi kulimba kwina, kukana kukhudza bwino komanso magwiridwe antchito abwino a khushoni, ndipo magwiridwe antchito a bolodi lopangidwa ndi PP ndi abwinoko; bolodi la PP lili ndi kuuma kwakukulu, mawonekedwe osalimba a makina, kulimba kochepa, komanso kukana kukhudza ndi khushoni koipa.

3. Kusiyana kwa zipangizo.

Bolodi la PP, yomwe imadziwikanso kuti pepala la polypropylene (PP), ndi chinthu chopangidwa ndi theka-kristalo. Ndi cholimba ndipo chimakhala ndi malo osungunuka kwambiri kuposa PE. Pepala la PE ndi utomoni wa thermoplastic wopangidwa ndi kristalo wochuluka, wosapangidwa ndi polar. Mawonekedwe a HDPE yoyambirira ndi oyera ngati mkaka, ndipo gawo lopyapyalalo ndi lowala pang'ono.
