1. Intangiriro
Polyethylene terephthalate (PET) nimwe mubintu byinshi ku isi kandi bikoreshwa cyane muri thermoplastique. Nibikoresho byibanze kumacupa y'ibinyobwa, gupakira ibiryo, hamwe na fibre synthique, PET ikomatanya ibintu byiza byumubiri hamwe nibisubirwamo. Iyi ngingo irasuzuma ibintu byingenzi biranga PET, uburyo bwo gutunganya, hamwe nuburyo butandukanye mu nganda.
2. Ibyiza
Ibintu bifatika
- Ikigereranyo Cyinshi-Kuri-Ibipimo: Imbaraga zingana za 55-75 MPa
- Ibisobanuro:> 90% byohereza urumuri (amanota ya kristalline)
- Ibyiza bya barrière: Kurwanya CO₂ / O₂ birwanya (byongerewe hamwe)
- Kurwanya Ubushyuhe: Bishobora kugera kuri 70 ° C (150 ° F) bikomeza
- Ubucucike: 1.38-1.40 g / cm³ (amorphous), 1,43 g / cm³ (kristaline)
Kurwanya imiti
- Kurwanya cyane amazi, alcool, amavuta
- Kurwanya biringaniye acide / base
- Kurwanya nabi alkalis ikomeye, ibishishwa bimwe
Umwirondoro wibidukikije
- Kode yo gusubiramo: # 1
- Hydrolysis Ibyago: Gutesha agaciro ubushyuhe bwinshi / pH
- Gusubiramo: Birashobora gusubirwamo inshuro 7-10 nta gihombo kinini
3. Uburyo bwo gutunganya
| Uburyo | Ibisanzwe | Ibitekerezo by'ingenzi |
|---|---|---|
| Gutera inshinge | Amacupa y'ibinyobwa | Icyerekezo cya Biaxial cyongera imbaraga |
| Gukabya | Filime, impapuro | Irasaba gukonjesha byihuse kugirango byumvikane |
| Kuzunguruka | Imyenda (polyester) | Kuzunguruka vuba kuri 280-300 ° C. |
| Thermoforming | Inzira y'ibiryo | Mbere yo gukama byingenzi (≤50 ppm ubuhehere) |
4. Ibyingenzi
Gupakira (73% by'ibisabwa ku isi)
- Amacupa y'ibinyobwa: miliyari 500 buri mwaka
- Ibikoresho birimo ibiryo: Microwavable tray, salade clamshells
- Imiti: Udupaki twa bliste, amacupa yimiti
Imyenda (22% isabwa)
- Fibre ya Polyester: Imyenda, hejuru
- Imyenda ya tekiniki: Umukandara, umukandara wa convoyeur
- Nonwovens: Geotextiles, itangazamakuru ryo kuyungurura
Imikoreshereze Yihuta (5% ariko ikura)
- Icapiro rya 3D: Imbaraga-zohejuru
- Ibyuma bya elegitoroniki: Gukingura firime, ibice bya capacitor
- Ingufu zisubirwamo: Urupapuro rwinyuma rwizuba
5. Iterambere rirambye
Ikoreshwa rya tekinoroji
- Gutunganya imashini (90% bya PET yongeye gukoreshwa)
- Gukaraba-flake-gushonga
- Urwego rwibiryo rusaba-gusukura cyane
- Gutunganya imiti
- Glycolysis / depolymerisation kuri monomers
- Inzira zidasanzwe
Bio-ishingiye kuri PET
- 30% by'ibimera bikomoka kuri MEG
- Ikoranabuhanga rya Coca-Cola ™ Ikoranabuhanga
- Igiciro kiriho: 20-25%
6. Kugereranya nubundi buryo bwa plastiki
| Umutungo | PET | HDPE | PP | PLA |
|---|---|---|---|---|
| Kugaragara | Cyiza | Opaque | Birasobanutse | Nibyiza |
| Koresha Koresha Temp | 70 ° C. | 80 ° C. | 100 ° C. | 55 ° C. |
| Inzitizi ya Oxygene | Nibyiza | Abakene | Guciriritse | Abakene |
| Igipimo cyo gusubiramo | 57% | 30% | 15% | <5% |
7. Ibihe bizaza
PET ikomeje kuganza imikoreshereze imwe gusa mugihe yagutse mubikorwa biramba binyuze:
- Ikoreshwa rya tekinoroji ya barrière (SiO₂ coatings, multilayer)
- Ibikorwa remezo byo gutunganya neza (PET)
- Guhindura imikorere (nano-igizwe, abahindura ingaruka)
Hamwe nuburinganire bwihariye bwimikorere, itunganywa kandi irashobora gukoreshwa, PET ikomeza kuba ingenzi mubukungu bwa plastike kwisi yose mugihe igenda yerekeza kumasoko azenguruka.
