Umehluko Phakathi kwe-PP Plastic ne-PE Plastic
I-PP ne-PE yizinto ezimbili zepulasitiki ezivame ukusetshenziswa, kodwa zihluke kakhulu ekusetshenzisweni kwazo. Isigaba esilandelayo sizoveza umehluko phakathi kwalezi zinto ezimbili.
| Igama leKhemikhali | I-polypropylene | polyethylene |
| Ukwakheka | Asikho Isakhiwo Sochungechunge Lwegatsha | Isakhiwo Seketango Elinegatsha |
| Ubuningi | 0.89-0.91g/Cm³ | 0.93-0.97g/Cm³ |
| I-Melting Point | I-160-170 ℃ | I-120-135 ℃ |
| Ukumelana Nokushisa | Ukumelana Nokushisa Okuphezulu Okuhle, Kungamelana Nezinga Lokushisa Elingaphezu kuka-100℃ | Ukumelana Nezinga Lokushisa Eliphezulu Kumpofu Ngokulinganiselwe, Imvamisa Ingamelana Kuphela Ku-70-80℃ Izinga Lokushisa Eliphezulu |
| Ukuvumelana nezimo | Ukuqina Okuphakeme, Kodwa Ukuguquguquka Okubuthakathaka | Ukuguquguquka Okuhle, Akulula Ukukuphula |
Igama lamakhemikhali, ukwakheka, ukuminyana, indawo encibilikayo, ukumelana nokushisa, nokuqina kwe-PP ne-PE kwehluka kakhulu njengoba kubonakala kuthebula elishiwo ngenhla. Lo mehluko unquma izinhlelo zabo zokusebenza ezihlukene.
Ngenxa yokuqina kwayo okuphezulu, ukuqina okubuthakathaka, ukumelana okuhle kakhulu kwezinga lokushisa eliphezulu, kanye nezakhiwo ezinhle zokuvala phakathi kwezinye izici, i-PP ivame ukuqashwa ekukhiqizeni amabhokisi epulasitiki, izigubhu zepulasitiki, izingxenye zezimoto, izesekeli zikagesi njll Ngakolunye uhlangothi, i-PE ithola. ukusetshenziswa kakhulu ekukhiqizeni amapayipi amanzi, izinto zokufaka ikhebula, nezikhwama zokudla ngenxa yokuqina kwayo okuncomekayo, ukumelana nokugqoka, ukuthamba, kanye nokumelana nezinga lokushisa eliphansi.
Ukubukeka kwe-PP ne-PE kungase kufane, kodwa izici zabo zokusebenza zihluke kakhulu. Ngakho-ke, ukukhethwa kwezicelo kufanele kusekelwe ezicini ezithile zezinto ezibonakalayo.
