Isifinyezo samapulasitiki (okufaka ukudla neziphuzo): asho ukuthini empilweni yethu?
Ipulasitiki ingase ibe yinto ehlukanisa kakhulu yezikhathi zanamuhla. Inikeza uchungechunge lwezinzuzo ezimangalisayo ezisisiza nsuku zonke. Ipulasitiki iphinde isetshenziswe ezinhlotsheni eziningi zokudla nokuphuza emaphaketheni. Basiza ukuvikela ukudla ekulimaleni. Kodwa ingabe uyazi kabanzi mayelana nomehluko wepulasitiki? Zisho ukuthini empilweni yethu?
● Yiziphi izinhlobo ezahlukene zamapulasitiki asetshenziswa ekupakisheni ukudla nasekuphuzeni?
Kungenzeka ukuthi uyibonile inombolo 1 kuya ku-7 ngezansi noma ohlangothini lwesitsha sokupakisha sepulasitiki. Le nombolo "ikhodi yokuhlonza i-resin," eyaziwa nangokuthi "inombolo yokugaya kabusha." Le nombolo ingaphinda inikeze isiqondiso kubathengi abafuna ukuvuselela iziqukathi zepulasitiki.
● Isho ukuthini inombolo esepulasitikini?
Ikhodi ye-Resin Identification noma inombolo yokugaya kabusha kupulasitiki ikhomba uhlobo lwepulasitiki. Lapha singathanda ukwabelana ngolwazi olwengeziwe mayelana namapulasitiki avamile asetshenziswa ekufakweni kokudla nokuphuza, atholakala e-Society of Plastics Engineers (SPE) kanye ne-Plastics Industry Association (PIA):
I-PETE noma i-PET (Inombolo yokugaya kabusha 1 / Ikhodi ye-Resin ID 1
 | Kwenzenjani: |
| I-Polyethylene terephthalate (i-PETE noma i-PET) ipulasitiki engasindi eyenziwe yaqina kancane noma iqine okwenzakunomthelela omkhulu ukumelana, futhi kusiza ukuvikela ukudla noma uketshezi ngaphakathi kwephakheji. | |
| Izibonelo: | |
| Amabhodlela eziphuzo, amabhodlela okudla/izimbiza (isaladi esigqoka, ibhotela lamantongomane, uju, njll.) kanye nezingubo ze-polyester noma intambo. | |
| Izinzuzo: | Ububi: |
| ●ukusetshenziswa okubanzi njenge-fiber●ngempumelelo kakhulu umswakama umgoqo ●i-shatterproof | ● Le pulasitiki iphephile uma kuqhathaniswa, kodwa kubalulekile ukuyigcina ingangeni ekushiseni noma ingabangela umdlavuza (njenge-flame retardant antimony trioxide) ukuthi ungene oketshezini lwakho. |
I-HDPE (Inombolo yokugaya kabusha 2 / Ikhodi ye-Resin ID 2)

| Izibonelo: | |
| Amapayipi amanzi, amakhadi esikweletu, amathoyizi abantu nezilwane ezifuywayo, amathoyizi emvula, izindandatho zamazinyo, izikhwama zoketshezi lwe-IV namashubhu ezokwelapha namamaski komoyampilo. | |
| Izinzuzo: | Ububi: |
| ●Kuqinile (nakuba izinhlobo ezahlukene ze-PVC empeleni zenzelwe ukuguquguquka)●Kunamandla;●Ukumelana nezinto eziphilayo namakhemikhali; | ● I-PVC inamakhemikhali athambisayo abizwa ngokuthi ama-phthalates aphazamisa ukukhula kwamahomoni; ●Ayikwazi ukusetshenziselwa ukupheka noma ukushisisa; |
I-LDPE (Inombolo yokugaya kabusha 4 / Ikhodi ye-Resin ID 4)
 | Kwenzenjani: |
| I-Low-density polyethylene (LDPE) izacile kunamanye ama-resin futhi ikwazi ukumelana nokushisa okuphezulu. Ngenxa yokuqina nokuguquguquka kwayo, i-LDPE isetshenziswa ngokuyinhloko ezinhlelweni zefilimu lapho kudingeka khona ukuvala ukushisa. | |
| Izibonelo: | |
| Ukugoqa kwepulasitiki/okunamathelayo, amasemishi nezikhwama zesinkwa, ukugoqa amabhamuza, izikhwama zikadoti, izikhwama zegrosa nezinkomishi zeziphuzo. | |
| Izinzuzo: | Ububi: |
| ●I-ductility ephezulu;● Ukumelana nokugqwala; | ● Amandla okuqina aphansi;●Ayikwazi ukuphinda isetshenziswe izinhlelo ezijwayelekile; |
I-PP (Inombolo yokugaya kabusha 5 / Ikhodi ye-Resin ID 5)
 | Kwenzenjani: |
| I-Polypropylene (PP) iqinile ngandlela-thile kodwa incane kakhulu kunamanye amapulasitiki. Ingenziwa i-translucent, i-opaque noma umbala ohlukile lapho ikhiqizwa. I-PP ngokuvamile inezinga eliphezulu lokuncibilika, okuyenza ifaneleke kakhulu imikhiqizo yokupakisha ukudla esetshenziswa kuma-microwave noma ehlanzwa kumshini wokuwasha izitsha. | |
| Izibonelo: | |
| Utshani, izikepisi zamabhodlela, amabhodlela kadokotela, izitsha zokudla okushisayo, iteyiphu yokupakisha, amanabukeni alahlwayo namabhokisi eDVD/CD. | |
| Izinzuzo: | Ububi: |
| ●ukusetshenziswa okuyingqayizivele kwamahinge aphilayo;● Ukumelana nokushisa; | ● Ibhekwa njengephephile i-microwave, kodwa sisaphakamisa ingilazi njengento engcono kakhulu yeziqukathi ze-microwave; |
I-PS (Inombolo yokugaya kabusha 6 / Ikhodi ye-Resin ID 6)
 | Kwenzenjani: |
| I-Polystyrene (PS) iyipulasitiki engenambala, eqinile engenakho ukuguquguquka okuningi. Ingenziwa ibe igwebu noma iphonswe isikhunta futhi inikezwe imininingwane emihle ngendlela yayo lapho yenziwa, isibonelo ibe yisimo sezipuni zepulasitiki noma izimfoloko. | |
| Izibonelo: | |
| Izinkomishi, iziqukathi zokudla okukhiphayo, ukuthunyelwa kwemikhumbi kanye nokupakishwa kwemikhiqizo, amabhokisi amaqanda, izinto zokusika kanye nokuvala amabhilidi. | |
| Izinzuzo: | Ububi: |
| ●Izicelo Zegwebu; | ● Ukuvuza amakhemikhali angaba ubuthi ,ikakhulukazi uma kushisa;● Kuthatha amakhulu ngamakhulu eminyaka ukubola. |
Okunye noma i-O (Inombolo yokugaya kabusha 7 / Ikhodi ye-Resin ID 7)
 | Kwenzenjani: |
| "Okunye" noma uphawu lwe-#7 emaphaketheni epulasitiki lubonisa ukuthi ukupakishwa kwenziwa nge-resin yepulasitiki ngaphandle kwezinhlobo eziyisithupha zama-resin ezibalwe ngenhla, isibonelo ukupakishwa kungenziwa nge-polycarbonate noma i-bioplastic polylactide (PLA) isibonelo, noma ingenziwa ngezinto ezingaphezu kweyodwa zepulasitiki. | |
| Izibonelo: | |
| Izibuko zamehlo, amabhodlela ezingane nawezemidlalo, izinto zikagesi, izinto zokukhanyisa nezinto zokusika zepulasitiki ezicacile. | |
| Izinzuzo: | Ububi: |
| ●Izinto ezintsha zinikeza imibono emisha mayelana nezimpilo zethu, njenge-Tritan material isetshenziswa kabanzi kumabhodlela e-hydration; | ● Ukusetshenziswa kwepulasitiki kulesi sigaba kusengozini yakho njengoba awazi ukuthi yini engase ibe kuyo. |
Lezi izinhlobo ezivame kakhulu zepulasitiki esihlangabezana nazo. Lokhu ngokusobala ulwazi oluyisisekelo kakhulu esihlokweni umuntu angachitha izinyanga ecwaninga. Ipulasitiki iyinto eyinkimbinkimbi, njengoba nje ukukhiqizwa kwayo, ukusatshalaliswa kanye nokusetshenziswa kwayo. Sikukhuthaza ukuthi ungene ujule ukuze uqonde zonke lezi zinkimbinkimbi, njengezakhiwo zepulasitiki, ukugaywa kabusha, izingozi zezempilo nezinye izindlela, okuhlanganisa okuhle nokubi kwe-bioplastics.
