Cov Evolution ntawm cov khoom lag luam retler hais txog lub xyoo pua-ntev kev tiv thaiv kom sib npaug nrog cov khoom siv ruaj khov. Niaj hnub nimno cov tshuab ua haujlwm ua haujlwm ua haujlwm polymers thiab composites tsim kho los ntawm kev ua haujlwm siab ua haujlwm tiv thaiv (escr) kev sim. Hauv qab no peb cais cov khoom genome secning niaj hnub no cov raj neeg muaj kev nyob sab.
1. Polymer Matrix Xaiv cov txheej txheem
1. Cov Khoom Xaiv Hinges ntawm rau (6))
2. Ciav tawm tsam nyob rau hauv pab txhawb nqa hydraulic load
3. Hydrolytic stability hla pH 3-11
4. UV-A / B Hluav Taws Xob Hluav Taws Xob (ntau dua lossis sib npaug rau 10 mJ / M²)
5. Puas Ua Haujlwm (ASTM D4060 tuser<50mg loss)
6. Thermal expansion sib xws (<80×10⁻⁶/°C)
7. Flammability rating (ul94 v -0 qhov tsawg kawg)
2. Kev Lag Luam Polymer Sib ntaus sib tua Royale
| Khoom | Kom zoo tshaj plaws matrix | Txwv kev ua haujlwm |
|---|---|---|
| PVC-U | {{0 {}}. 5% nqus dej - 55 mpa tensile - Nqi: $ 2.5 / kg |
- tg =85 degree (thermal Sag) - Tsis tsim nyog chloramine tsis kam |
| PP-Homo | {{0 {}}. 3 g / cm³ ntom {{0 {}}, 500 h xenon arc stability - FDA-LAWV |
- Notch Paub Txog - CTE =110 × × 10⁻⁶ / degree |
| HDPE | - ESCR >1,000 h - -40 degree cuam tshuam kev tuav - Tshuaj lom neeg inertness |
- 25 MPA Flexcural Modulus - UV kho kom ruaj khov |
| Pvdf | - 140 degree kev pabcuam nruam {{0 {}}. 78 g / cm³ ntom {{0 {0}}. 03% nkag (70 degree / 10Mpa) |
- 8 × pvc nqi - nyuaj thermoforming |
3. Requinfed Composite Frontier
• iav-fiber pp (gf30):
• 80% ↑ Flucural zog vs. nkauj xwb pp
• {{0 {0}}. 6 hli / m shrakeage (pwm ntws optimized)
• Cov Ntawv Thov: Cov Khoom Siv Hluav Taws Xob Me
• Carbon Nanotube HDPE:
• 50% ↑ thermal conductivity rau dej khov-prone cheeb tsam
• EMI Tiv Thaiv Kom Sensor-Sib Koom Tes Sib Koom
• 3D-Printable Daim Qauv Tawm Tshiab
• Puag tsev PVC puv puv PVC:
• Wollastonite (CasioT₃) Qhov Cuab Lub Zog:
• 40% ↑ Puas Ua Dej
• {{0 {0}}. 8 g / cm³ ntom txo
• Titanium Dioxide UV Kev Ntsuam Xyuas
4. Tshem tawm lub neej ntsuas lub neej
Kwv yees {20- xyoo ua tau zoo los ntawm:
1. QV-ASTMD4587: 5, {000 h uv / hws cycling
2. Hydrolytic laus: 85 Qib / PH10 Immersion (sib npaug rau 15 xyoo)
3. Pob-ntawm-tiaj tus coj mus kuaj: 10n Thauj, 1Hz, 100km Zawv Zawg
Cov Ntaub Ntawv Ntaub Ntawv: GFPP SUPRIGNTED<5% transmittance loss after 8-year field deployment vs. 22% in standard PP.
5. Tawm cov kev xaiv xyoob ntoo los ntawm kev hloov pauv
PLA-pha blends:
60% bio-cov ntsiab lus
7.5 GPA Modulus (thiab PVC tus 3.5 GPA)
Compostable Eol Xaiv
Lignin-txhawb nqa petg:
30% ↑ hardness ntawm ligignin nanocrystals
200 degree hdt rau thermal kom tsis muaj menyuam
Xaiv cov algorithm:
1. Xam cov shear tus nqi () {1}}}}} · he²)
2. Phim rau Polymer Mart Flow Index (MFI)
3.. Tshawb xyuas cov tshuaj sib raug zoo ntawm HSP (Hansen Solubility tsis muaj)
4. Txhim kho rau tag nrho cov nqi ntawm cov tswv cuab (TCO)
Vim li cas cov khoom muaj teeb meem:
Cov khoom lag luam zoo tshaj plaws cov khoom tsis muaj nyob nrog kev cuam tshuam los ntawm kev cuam tshuam ntawm cov kev ua haujlwm zoo ntawm cov hydraulic, muaj sia. Tom ntej no cov kev cog lus tom ntej no 30- kev pabcuam hauv kev tawm tsam thaum enabling detimentation los ntawm cov sensors.
