Iibhotile zeplastikiziye zaba yinxalenye ebalulekileyo yobomi bethu bemihla ngemihla.Siwasebenzisela ukugcina amanzi, iziselo, kwanabacoci bamakhaya.Kodwa ngaba ukhe waqaphela iisimboli ezincinci ezibhalwe emazantsi ezi bhotile?Baphethe ulwazi oluxabisekileyo malunga nohlobo lweplastiki esetyenzisiweyo, imiyalelo yokuhlaziya, kunye nokunye okuninzi.Kule bhlog, siza kuphonononga iintsingiselo ezingemva kwezi simboli kunye nokubaluleka kwazo ekuqondeni iiplastiki esizisebenzisayo.
Iibhotile zeplastiki zibhalwe ngophawu olunxantathu olubizwa ngokuba yiResin Identification Code (RIC).Olu phawu luquka inani elisuka ku-1 ukuya ku-7, elivalelwe phakathi kweentolo ezileqayo.Inani ngalinye limele uhlobo olwahlukileyo lweplastiki, inceda abathengi kunye nezixhobo zokurisayikilisha ukuba zichonge kwaye zihlele ngokufanelekileyo.
Masiqale ngesona simboli sisetyenziswa kakhulu, inombolo 1. Imele iPolyethylene Terephthalate (PET okanye iPETE) – iplastiki efanayo esetyenziswa kwiibhotile zesiselo.I-PET yamkelwa ngokubanzi ngeenkqubo zokurisayikilishwa kwakhona kwaye inokuphinda isetyenziswe kwiibhotile ezintsha, ifayibha yokugcwaliswa kweebhatyi, kunye nekhaphethi.
Ukuqhubela phambili kwinombolo ye-2, sine-High-Density Polyethylene (HDPE).Le plastiki iqhele ukusetyenziswa kwiijagi zobisi, iibhotile zokucoca, kunye neengxowa zegrosari.I-HDPE iyakwazi ukurisayikilisha kwaye iguqulwa ibe ngamaplanga eplastiki, imibhobho, nemigqomo yokurisayikilisha.
Inombolo 3 imele iPolyvinyl Chloride (PVC).I-PVC isetyenziswa ngokuqhelekileyo kwimibhobho yamanzi, iifilimu zokubambelela, kunye nokupakishwa kwe-blister.Nangona kunjalo, i-PVC ayisebenzi lula kwaye ibeka imingcipheko yokusingqongileyo ngexesha lemveliso kunye nokulahlwa.
Inombolo yesi-4 imele i-Low-Density Polyethylene (LDPE).I-LDPE isetyenziswa kwiingxowa zegrosari, kwiiplastiki ezisongayo, kunye neebhotile ezicudiswayo.Ngelixa inokuphinda isetyenziswe ukusa kumlinganiselo othile, ayizizo zonke iinkqubo zokurisayikilishwa ziyayamkela.Iingxowa eziphinda zisetyenziswe kunye nefilimu yeplastiki zenziwe nge-LDPE ephinda isetyenziswe.
I-Polypropylene (PP) yiplastiki echazwe ngenombolo 5. I-PP ifumaneka ngokuqhelekileyo kwiibhotile ze-yogurt, iibhotile zebhotile, kunye ne-cutlery elahlayo.Inendawo yokunyibilika ephezulu, nto leyo eyenza ukuba ilungele izikhongozeli ezikhuselekileyo kwi-microwave.I-PP inokuphinda isetyenziswe kwaye ijikwe ibe zizibane zesignali, imigqomo yokugcina, kunye neemeko zebhetri.
Inombolo 6 yeyePolystyrene (PS), eyaziwa ngokuba yiStyrofoam.I-PS isetyenziswa kwizikhongozeli zokuthatha, iikomityi ezilahlwayo, kunye nezinto zokupakisha.Ngelishwa, kunzima ukurisayikilisheka kwaye akwamkelwa ziinkqubo ezininzi zokurisayikilisha ngenxa yexabiso layo eliphantsi lemarike.
Okokugqibela, inani lesi-7 libandakanya zonke ezinye iiplastiki okanye imixube.Iquka iimveliso ezifana ne-polycarbonate (i-PC) esetyenziswa kwiibhotile zamanzi eziphinda zisetyenziswe, kunye neeplastiki ezinokubola ezenziwe ngezinto ezisekelwe kwizityalo, kunye nezinto ze-Tritan ezivela e-Eastman, kunye ne-Ecozen evela kwikhemikhali ye-SK.Ngelixa ezinye iiplastiki zenombolo 7 ziphinda zisetyenziswe, ezinye azinjalo, kwaye ukulahlwa ngokufanelekileyo kubalulekile.
Ukuqonda ezi mpawu kunye neeplastiki ezihambelana nazo kunokunceda kakhulu ekunciphiseni inkunkuma kunye nokukhuthaza iindlela ezifanelekileyo zokusebenzisa kwakhona.Ngokuchonga iindidi zeplastiki esizisebenzisayo, sinokwenza izigqibo ezizizo malunga nokuphinda zisetyenziswe, ukurisayikilisha, okanye ukuzilahla ngokufanelekileyo.
Ngexesha elizayo xa ubamba ibhotile yeplastiki, thatha umzuzwana ujonge isimboli esezantsi kwaye uqwalasele impembelelo yayo.Khumbula, izenzo ezincinci ezifana nokurisayikilisha zingenza umahluko omkhulu ekukhuseleni okusingqongileyo.Sikunye, masilwela ikamva eliluhlaza nelizinzileyo.
