Kusiyana Pakati pa PP Plastic ndi PE Plastic
PP ndi PE ndi zida ziwiri zapulasitiki zomwe zimagwiritsidwa ntchito nthawi zambiri, koma zimasiyana kwambiri pakugwiritsa ntchito kwawo. Gawo lotsatirali lifotokoza za kusiyana kwa zida ziwirizi.
| Mankhwala Name | Polypropylene | polyethylene |
| kapangidwe | Palibe Mapangidwe a Nthambi ya Nthambi | Kapangidwe ka Unyolo Wanthambi |
| kachulukidwe | 0.89-0.91g/Cm³ | 0.93-0.97g/Cm³ |
| Melting Point | 160-170 ℃ | 120-135 ℃ |
| Kutentha kwamoto | Kukana Kwabwino Kwa Kutentha Kwambiri, Kumatha Kupirira Kutentha Kwambiri Kupitilira 100 ℃ | Kukana Kutentha Kwambiri Ndikovuta Kwambiri, Nthawi zambiri Kumatha Kupirira 70-80 ℃ Kutentha Kwambiri |
| kusinthasintha | Kuuma Kwambiri, Koma Kusasinthika Kwambiri | Kusinthasintha Kwabwino, Osavuta Kuswa |
Dzina lamankhwala, kapangidwe kake, kachulukidwe, malo osungunuka, kukana kutentha, komanso kulimba kwa PP ndi PE zimasiyana kwambiri monga zikuwonekera patebulo lomwe latchulidwa pamwambapa. Kusiyanitsa uku kumatsimikizira ntchito zawo zosiyanasiyana.
Chifukwa cha kuuma kwake kwakukulu, kulimba kosalimba, kukana kutentha kwakukulu, ndi katundu wabwino wotsekemera pakati pa makhalidwe ena, PP imagwiritsidwa ntchito popanga mabokosi apulasitiki, ng'oma zapulasitiki, mbali za galimoto, zipangizo zamagetsi etc. Komano, PE imapeza. ntchito kwambiri popanga mipope madzi, zipangizo kutchinjiriza chingwe, ndi matumba chakudya chifukwa chotamandika kulimba, kukana kuvala, kufewa, ndi kutsika kutentha kukana.
Maonekedwe a PP ndi PE angakhale ofanana, koma machitidwe awo amasiyana kwambiri. Choncho, kusankhidwa kwa ntchito kuyenera kukhazikitsidwa ndi zinthu zinazake.
