Isingeniso
Ngesikhathi lapho ukukhathazeka kwezemvelo kuthatha indawo yesikhungo, ukufunwa kwezinye izindlela ezinobungane kumapulasitiki wendabuko kuholele ekuqhamuke nokuvela kwezinto ezintsha ezifana ne-polylactic acid (PLA). Kulesi sifundo sebhulogi, sizokwelulwa endaweni ye-PLA, ehlola umsuka wayo, izakhiwo, izinhlelo zokusebenza, kanye nomthelela wezemvelo. Inhloso yethu ukucacisa ukuthi i-PLA ibumba kanjani ikusasa lamapulasitiki.
Yini i-polylactic acid (PLA)?
I-Polylactic acid, noma i-PLA, i-thermoplastic ye-biodergradable ne-bioderactive etholakala emithonjeni evuselelekayo efana nesitashi sommbila noma umoba. Yakhiwa nge-polymerization ye-lactic acid futhi ivelele kusuka ku-plastitics evamile ngenxa ye-biodegrade yayo ehlukile kanye nokwenziwa.
Izakhiwo ze-pla
I-PLA inezindawo ezimbalwa ezibalulekile ezenza kube ngenye indlela ephoqelelayo yamapulasitiki wendabuko:
- Ukusobala nokubukeka: I-PLA yaziwa ngokusobala kwayo, okwenza ilungele izinhlelo zokusebenza lapho ama-arehetics afana khona.
- Amandla nokuqina: Kubonisa amandla amahle nokuqina, ukuhlanganisa amapulasitiki ajwayelekile afana nesilwane esifuywayo.
- Ukumelana nokushisa: Ngenkathi i-PLA ingamelana namazinga okushisa alinganiselayo, ingahle iguquke emazingeni okushisa aphezulu uma kuqhathaniswa namapulasitiki afana I-Polypropylene (PP).
- Izakhiwo ezibanda: I-PLA inganikeza izakhiwo ezinesithiyo esanele sohlelo oluthile, yize kungadinga ukuguqulwa kwezidingo ezifunwa kakhulu.
Inqubo Yokukhiqiza
Ukukhiqizwa kwepla kuqala ngokukhishwa koshukela ovuthayo kusuka ezitshalweni ezinjengommbila noma umoba. Lolu shukela bese luguqulwa lube yi-lactic acid ngenqubo yokuvutshelwa. Kamuva, i-PLA POLMERIWARIONS yenzeka, okuholela ekwakhekeni kwama-resin pellets asetshenziswa ezinhlelweni ezahlukahlukene. Inzuzo eyodwa ephawuleka kakhulu yokukhiqizwa kwe-PLA yiso le-Carbon Footprint yayo encishisiwe, njengoba lincike kwizinsizakusebenza ezivuselelekayo futhi lisebenzisa amandla amancane kunawo wonke amapulasithi asuselwa ku-petroleum.
Izicelo Pla
Ukusebenza kabusha kwe-Pla kuholele ekutholeni kwayo emikhakheni ehlukahlukene kanye nezicelo:
- Ukupakishwa kokudla: I-PLA ivame ukusetshenziselwa iziqukathi zokudla, ama-cutlery, kanye namafilimu okudla ngenxa ye-biodegradeality yakhe kanye nemvelo engeyona ingozi.
- Ukuphrinta kwe-3D: Ukukhululeka kwayo kokuphrinta ne-biodegradabilibility yenza i-PLA iyintandokazi emphakathini wokuphrinta we-3D wokwenza ama-prototypes, amathoyizi, kanye nezingcezu zobuciko.
- Izindwangu kanye nezingubo: Izindwangu ezisuselwa ku-Pla zivela njengezinye izindlela ezizinzile embonini yezemfashini, zinikeza izinzuzo njengokuphefumula kanye nomswakama-winging.
- Amadivaysi ezokwelapha: I-BIOCHATI YOKUFAKWA KWE-PLA yenza ukuthi ilungele ukusetshenziswa kwezokwelapha okufana nezisulu nezinhlelo zokulethwa kwezidakamizwa.
Umthelela Wezemvelo
I-PLA inikeza izinzuzo ezibalulekile zemvelo:
- Kuncishiswe ukuphuma kwegesi ebamba ukushisa: I-PLA Production ikhiqiza ukuphuma okumbalwa kwegesi abamba ukushisa uma kuqhathaniswa namapulasitiki asuselwa ku-petroleum.
- I-Biodegradeabilibility kanye Composturability: Pla kungaba biodegade ngaphansi kwemibandela ethile, ukunciphisa imfucuza yepulasitiki ekulahlekelweni komhlaba kanye nolwandle.
- Kunciphise ukuncika kwamafutha e-fossil: Ukuthembela kukaPla kwizinsizakusebenza kabusha kunciphisa ukuncika kwethu kumafutha emifela.
Kubalulekile ukuqaphela ukuthi i-biodegradadation esebenza kahle ye-PLA idinga izimo ezithile zokubumba zezimboni, okungenzeka kungatholakali emhlabeni wonke.
Pla vs plastiti yendabuko
Ukuze uqonde kangcono izinzuzo ze-PLA, ake siluqhathanise namapulabala endabuko:
| Impahla | Ipla | Thinta ngothando | I-PUT |
|---|---|---|---|
| I-Biodegradability | Yebo | -Nokuba | -Nokuba |
| Ukungafihli | -Phezulu | -Phezulu | -Ehlile |
| Amandla nokuqina | Kuhle ngokuncomekayo | -Hle kakhulu | Kuhle ngokuncomekayo |
| Ukumelana nokushisa | -Ngeqile | -Phezulu | -Phezulu |
| Umthombo wokukhiqiza | Ukuvuselelwa (izitshalo) | Ama-Fossil Fuels (Petroleum) | Ama-Fossil Fuels (Petroleum) |
| Umthelela Wezemvelo | Isithonjana sekhabhoni esiphansi | I-Carbon Footprint ephezulu | I-Carbon Footprint ephezulu |
Ngenkathi i-PLA idlula e-biodegradability kanye nesisekelo sekhabhoni encishisiwe, ingahle ibe nemikhawulo yokuvikelwa kokushisa kwezinhlelo ezithile.
Amathemba esikhathi esizayo nezinselelo
Ikusasa le-PLA linesithembiso nezinselelo ngokufanayo. Abaphenyi bayaqhubeka nokusebenza ekuthuthukiseni izakhiwo zalo, ikakhulukazi ukumelana nokushisa, ukunwebisa uhla lwalo lwezicelo. Impumelelo ye-PLA ibuye yathuthuka ekuthuthukisweni kabusha kwengqalasizinda ethuthukisiwe kanye nokukhohlisa ingqalasizinda ukukhulisa izinzuzo zayo zemvelo.
Isiphetho
Ekuphokopheleni kwezinye izindlela zepulasitiki ezizinzile, i-polylactic acid (PLA) ikhanya njengekhatho lethemba. Ngokuthola i-biodegradeabilibility yayo, ukuguquguquka okuvuselelayo, kanye nokuguquguquka, i-PLA inikezela ngesisombululo esiphoqayo ukunciphisa ukungcoliswa kwepulasitiki nokuncika kwethu kumafutha e-fossil. Njengoba sihlola izindlela zokuvikela iplanethi yethu, i-PLA isebenza njengesibonelo sokuthi amasha angavuselela kanjani indlela eya ngekusasa elizinzile.
