1. Selelekela
Polyethylene terephthalate (PET) ke e 'ngoe ea li-thermoplastics tse sebetsang ka ho fetisisa lefatšeng le tse sebelisoang haholo. E le thepa ea mantlha ea libotlolo tsa lino, liphutheloana tsa lijo le likhoele tsa maiketsetso, PET e kopanya thepa e ntle ea 'mele le ho sebelisoa hape. Sengoliloeng sena se hlahloba litšobotsi tsa mantlha tsa PET, mekhoa ea ts'ebetso, le lits'ebetso tse fapaneng liindastering tsohle.
2. Thepa Thepa
Thepa ea 'Mele le Mechini
- Karolelano e Phahameng ea Matla le Boima: Matla a tsitsitseng a 55-75 MPa
- Ho hlaka: >90% phetiso ea leseli (limaraka tsa kristale)
- Thepa ea Barriers: Ho hanyetsa CO₂/O₂ e ntle (e ntlafalitsoe ka liphahlo)
- Thermal Resistance: E sebetsa ho fihlela ho 70°C (150°F) kamehla
- Boima: 1.38-1.40 g/cm³ (amorphous), 1.43 g/cm³ (crystalline)
Khanyetso ea Lik'hemik'hale
- Ho hanyetsa ka mokhoa o babatsehang ho metsi, joala, oli
- Ho hanyetsana le li-acid tse fokolang / metheo
- Ho hanana hantle le li-alkali tse matla, li-solvents tse ling
Boemo ba Tikoloho
- Recycling Code: #1
- Kotsi ea Hydrolysis: E theoha mocheso o phahameng/pH
- Recyclability: E ka sebelisoa hape makhetlo a 7-10 ntle le tahlehelo e kholo ea thepa
3. Mekhoa ea ho sebetsa
| Mokhoa | Lisebelisoa tse Tloaelehileng | Lintlha Tse ka Sehloohong |
|---|---|---|
| Ente Otlolla Sephatlo Molding | Libotlolo tsa seno | Biaxial orientation e ntlafatsa matla |
| Extrusion | Lifilimi, lipampiri | E hloka ho pholisoa ka potlako bakeng sa ho hlaka |
| Fiber Spinning | Textile (polyester) | Ho ohla ka lebelo le phahameng ho 280-300°C |
| Thermoforming | Literei tsa lijo | Ho omisa ho bohlokoa (≤50 ppm mongobo) |
4. Likopo tse kholo
Ho paka (73% ea tlhoko ea lefats'e)
- Libotlolo tsa Beverage: li-unit tse limilione tse likete tse 500 selemo le selemo
- Lijana tsa Lijo: Li-tray tse ka tšeloang ka microwave, li-clamshell tsa salate
- Meriana: Lipakete tsa blister, libotlolo tsa meriana
Masela (22% tlhoko)
- Polyester Fiber: Liaparo, upholstery
- Lisebelisoa tsa Tekheniki: Mabanta a litulo, mabanta a conveyor
- Li-Nonwovens: Geotextiles, mecha ea litaba ea filtration
Lisebelisoa tse hlahang (5% empa li ntse li hola)
- Khatiso ea 3D: Lifilamente tse matla haholo
- Electronics: Lifilimi tse sireletsang, likarolo tsa capacitor
- Matla a Tsosolositsoeng: Li-backsheets tsa solar panel
5. Tsoelo-pele ea Moshoelella
Recycling Technologies
- Mechanical Recycling (90% ea PET e tsosolositsoeng)
- Hlatsoa-flake-qhibiliha mokhoa
- Boemo ba lijo bo hloka tlhoekiso e kholo
- Tšebeliso ea Lik'hemik'hale
- Glycolysis / depolymerization ho monomers
- Mekhoa e hlahang ea enzymatic
Bio-E thehiloeng PET
- 30% likarolo tsa MEG tse nkiloeng ke semela
- Theknoloji ea Coca-Cola's PlantBottle™
- Litšenyehelo tsa hona joale: 20-25%
6. Papiso le Alternative Plastics
| Thepa | PET | HDPE | PP | PLA |
|---|---|---|---|---|
| Ho hlaka | E kgabane | Opaque | Translucent | E ntle |
| Max Sebelisa Temp | 70°C | 80°C | 100°C | 55°C |
| Thibelo ea Oksijene | E ntle | Mafutsana | E itekanetseng | Mafutsana |
| Recycling Rate | 57% | 30% | 15% | <5% |
7. Pono ea Bokamoso
PET e ntse e tsoela pele ho laola liphutheloana tsa tšebeliso e le 'ngoe ha e ntse e hola ho ba lits'ebetso tse tšoarellang ka:
- Theknoloji e ntlafalitsoeng ea lithibelo (liaparo tsa SiO₂, multilayer)
- Lisebelisoa tse tsoetseng pele tsa ho tsosolosa (PET e entsoeng ka lik'hemik'hale)
- Liphetoho tsa ts'ebetso (li-nano-composites, li-modifiers tsa phello)
Ka tekanyo ea eona e ikhethang ea ts'ebetso, ts'ebetso le ts'ebetsong, PET e ntse e le ea bohlokoa haholo moruong oa lipolasetiki tsa lefats'e ha e ntse e fetela ho mefuta e chitja ea tlhahiso.
