Nakuba i-PP (i-polypropylene) kanye ne-PVC (i-polyvinyl chloride)izifiki ze-lamella tubezisetshenziswa ezinqubweni zokuhlanza amanzi, kunomehluko omkhulu ezimpahleni zezinto ezibonakalayo, ukusebenza kanye nezindlela zokufaka.
1. Umehluko Wezinto Ezibalulekile
| Into | PP | I-PVC |
| Ubuningi (g/cm3) | 0.9-0.91 | 1.38-1.45 |
| Indawo yokuncibilika (℃) | 160-170 | 75-90 |
| Izinga lokushisa lokuhlanekezela ukushisa (℃) | 110（0.45MPa） | 65（0.45MPa） |
| I-coefficient yokwandisa okuqondile | 1.5×10⁻⁴/℃ | 6×10⁻⁵/℃ |
| Amandla okudonsa (MPa) | 30-40 | 50-60 |
2. Ukuqhathaniswa kwezakhiwo zemishini
| Into | PP | I-PVC |
| Ukumelana nomthelela | Kusobala ukuthi iyaphuka (<0 ℃) | Gcina ukuqina (-15 ℃) |
| Ingcindezi yesikhathi eside | Ukuklebhuka kuvame ukwenzeka ngaphansi komthwalo oqhubekayo (ukusekelwa kudinga ukuqiniswa) | Ukumelana okuhle kokunyenya |
| Impilo yesevisi | Iminyaka emi-3-5 | Kude ngo-20%-30% kune-PP |
| Imvamisa yokulungisa | Iminyaka emi-3 | Iminyaka emi-5 |
3. Umehluko ekuphathweni kwamanzi
| Into | PP | I-PVC |
| Ububushelelezi bomphezulu | 0.8-1.2μm | 0.4-0.6μm |
| I-engeli yokushelela kodaka | 55°-60° | 50°-55° |
| Ukunamathela kwe-Biofilm | Kubuthakathaka (okungenawo umoya) | Okuqinile (indawo ephansi) |
| Izinga lokugeleza komklamo (m/h) | 1.0-1.5 | 0.8-1.2 |
4. Umehluko ekufakweni
I-PP: Ukushisela umoya oshisayo (260-300 ℃) kumele kusetshenziswe
I-PVC: Ingahlanganiswa nezinyibilikisi noma ihlanganiswe emazingeni okushisa aphansi (180-220 ℃)
