Musiyano Pakati pePP Plastic uye PE Plastic
PP nePE zvinhu zviviri zvepurasitiki zvinowanzo shandiswa, asi zvinosiyana zvakanyanya mumashandisirwo azvo. Chikamu chinotevera chicharatidza mutsauko pakati pezvinhu zviviri izvi.
| Kemikari Name | Polypropylene | Polyethylene |
| mamiriro | Hapana Branching Chain Mamiriro | Branched Chain Structure |
| Density | 0.89-0.91g/Cm³ | 0.93-0.97g/Cm³ |
| Melting Point | 160-170 ° C | 120-135 ° C |
| Kupisa Kupisa | Yakanaka Yepamusoro Tembiricha Kuramba, Inogona Kumira Kupfuura 100 ℃ Yepamusoro Tembiricha | Yakakwira Tembiricha Kupokana Kwakashata, Kazhinji Inogona Kumira Chete 70-80℃ Yepamusoro Tembiricha. |
| Kubvuma sanduko | Kuoma Kwakakwirira, Asi Kwakashata Kuchinja | Kunaka Kuchinjika, Kwete Nyore Kutyora |
Zita remakemikari, chimiro, density, nzvimbo inonyunguduka, kupisa kupisa, uye kuoma kwePP nePE zvinosiyana zvakanyanya sezvinoonekwa kubva patafura yambotaurwa. Iyi misiyano inosarudza maitiro avo akasiyana.
Nekuda kwekuoma kwayo kwakanyanya, kusasimba kwesimba, kusimba kwekushisa kwakanyanya, uye kunaka kwekudzivirira zvinhu pakati pehumwe hunhu, PP inowanzoshandiswa mukugadzira mabhokisi epurasitiki, madhiramu epurasitiki, zvikamu zvemotokari, zvigadzirwa zvemagetsi nezvimwe. Ukuwo, PE inowana. kushandiswa kwakawanda mukugadzira mapaipi emvura, tambo yekuvharisa zvinhu, uye mabhegi ezvekudya nekuda kwekusimba kwayo kunoyemurika, kupfeka kuramba, kupfava, uye kushomeka kwekushisa.
Chitarisiko chePP uye PE chinogona kunge chakafanana, asi maitiro avo ekuita anosiyana zvakanyanya. Naizvozvo, kusarudzwa kwezvikumbiro kunofanirwa kuve kwakavakirwa pane chaiwo maitiro ezvinyorwa.
