Kunyangwe PP (polypropylene) uye PVC (polyvinyl chloride)nzvimbo dze lamella tubeZvinoshandiswa mukugadzirisa mvura, pane musiyano mukuru muhunhu hwezvinhu, mashandiro uye nzira dzekuisa.
1. Musiyano weZvinhu
| Chinhu | PP | PVC |
| Kuwanda (g/cm3) | 0.9-0.91 | 1.38-1.45 |
| Nzvimbo yekunyunguduka (℃) | 160-170 | 75-90 |
| Kupisa kukanganiswa kwekupisa (℃) | 110（0.45MPa） | 65（0.45MPa） |
| Kukura kwemutsetse kwekodheni | 1.5×10⁻⁴/℃ | 6×10⁻⁵/℃ |
| Simba rekusimba (MPa) | 30-40 | 50-60 |
2. Kuenzanisa kwehunhu hwemakanika
| Chinhu | PP | PVC |
| Kuramba kukanganiswa | Zviri pachena kuti haina kusimba (<0 ℃) | Ramba uchitsungirira (-15℃) |
| Kumanikidzwa kwenguva refu | Kukambaira kunowanzoitika kana munhu achitakura zvinhu zvinorema nguva dzose (rutsigiro runofanira kusimbiswa) | Kudzivirira kwakanaka kwekufamba |
| Hupenyu hwebasa | Makore 3-5 | Yakareba 20%-30% kupfuura PP |
| Kugadziriswa kwenguva refu | Makore matatu | Makore mashanu |
3. Kusiyana mukurapa kwemvura
| Chinhu | PP | PVC |
| Kutsvedzerera kwepamusoro | 0.8-1.2μm | 0.4-0.6μm |
| Kona yekutsvedza kwematope | 55°-60° | 50°-55° |
| Kunamatira kweBiofilm | Kusasimba (kusingatyisi mvura) | Yakasimba (pamusoro pe polar) |
| Mwero wekuyerera kwedhizaini (m/h) | 1.0-1.5 | 0.8-1.2 |
4. Kusiyana pakuiswa
PP: Kupisa mhepo yekuwedera (260-300 ℃) kunofanira kushandiswa
PVC: Inogona kubatanidzwa nezvinhu zvinonyungudutsa kana kusungirirwa patembiricha yakaderera (180-220 ℃)
