Iplastiki ifumaneka kuyo yonke indawo kubomi bethu bemihla ngemihla, akunjalo? Ukususela ekhitshini ukuya kwiimoto esizisebenzisayo, yonke into yenziwe ngeplastiki. Ngenxa yokuba ixhaphake kakhulu, sihlala sicinga ukuba zonke ezi ntlobo zeplastiki zikhuselekile kwimpilo yethu. Kodwa ngaba kunjalo ngokwenene? Ngeentlobo ezahlukeneyo zeekhompawundi zeplastiki, sazi njani ukuba zeziphi ezilungileyo kwimpilo yethu kwaye zeziphi ezimbi? Izinto ezininzi esizisebenzisayo, kuquka izixhobo zasekhitshini kunye neebhokisi zesidlo sasemini, ziqulethe uhlobo olubizwa ngokuba yi-polypropylene. Makhe sithethe ngale nto namhlanje.
Yintoni le polypropylene?
Ngamafutshane, i-polypropylene luhlobo lweplastiki. Isetyenziselwa ukwenza yonke into ukusuka kwiikomityi zeyogathi ezithengwa evenkileni ukuya kwiibhotile zamanzi ukuya kwiibhokisi zesidlo sasemini. Enye yeenzuzo zayo ezinkulu kukuba inokuphinda isetyenziswe ngokulula. Yiyo loo nto iye yaba yenye yezona ntlobo zeplastiki zidumileyo kwihlabathi lanamhlanje.
Ungabona ngokulula ukuba into yeplastiki yenziwe nge-polypropylene. Ukuba inombhalo othi '5' ngaphakathi kophawu lokuphinda isetyenziswe olunxantathu ezantsi, oko kuthetha ukuba yenziwe nge-polypropylene.
Isetyenziselwa ntoni i-polypropylene?
I-Polypropylene luhlobo lweplastiki oluluncedo kakhulu. Isetyenziswa kwiindawo ezininzi ngenxa yokuqina kwayo, ixabiso layo liphantsi, kunye nokuguquguquka kwayo. Makhe sibone ukuba isetyenziselwa ntoni ikakhulu.
| Indawo yokusetyenziswa | Imizekelo |
|---|---|
| Ukupakisha | Ngenxa yokuba ziqinile kakhulu kwaye zingabizi kakhulu, zisetyenziselwa ukwenza izinto ezifana neekomityi zeyogathi, iikomityi zokusela, iibhotile zamanzi, kunye nezikhongozeli zokutya. |
| Izinto zasekhaya | Iplastiki emakhayeni ethu isetyenziswa kakhulu ekwenzeni izinto ezisetyenziswa ngabantu ezifana nezitulo, iitafile, izinto zokudlala, kunye nemithwalo. |
| Izixhobo zezithuthi | Ngenxa yokuba ingabizi kakhulu kwaye inokubunjwa ngokulula ibe yimo oyifunayo, isetyenziselwa ukwenza iibhampa, izigqubuthelo zebhetri, iiphaneli zangaphakathi zomnyango, kunye neephaneli zezixhobo kwiimoto nakwiiveni. |
| Izicelo zonyango | Ngenxa yokuba azixhathisi kwiikhemikhali nakwiibhaktheriya, zisetyenziselwa ukwenza izinto ezifana neesirinji zokujova, iitreyi zokutya zasesibhedlele, iikomityi zamayeza, kunye nezitya zePetri. |
Ngaba oku kune-BPA eyingozi?
Nazi iindaba ezimnandi! I-Polypropylene ayinayo i-Bisphenol-A (BPA).
I-BPA yikhemikhali esetyenziselwa ukuqinisa iplastiki. Ibisetyenziswa ekupakisheni ukutya ukususela ngeminyaka yoo-1960.
Uphando lubonise ukuba xa ufudumeza izinto ezifana nezikhongozeli zeplastiki, iipleyiti, kunye neebhotile, le khemikhali ebizwa ngokuba yi-BPA iyanyibilika kwiplastiki ize ingene ekutyeni esikutyayo. Ayilunganga loo nto konke konke. Kuba xa i-BPA ingena emizimbeni yethu, iqala ukusebenza njengehomoni ye-estrogen emizimbeni yethu. Oku kunokubangela iingxaki ezininzi zempilo. Umzekelo, inokutshintsha ukusebenza kwenkqubo yomzimba yokuzikhusela, ichaphazele amandla okuba nabantwana, ikhawulezise ukufikisa kwamantombazana, kwaye yonyuse umngcipheko wesifo sentliziyo.
Ngoko ke, soloko ukhangela ilebhile ethi “ayina-BPA” xa uthenga iimveliso zeplastiki. Kwakhona, ziphephe iiplastiki ezineekhowudi zokurisayikilisha 3 okanye 7, njengoko zinokuba ne-BPA. Ziphephe ukufudumeza izikhongozeli zeplastiki kwi-microwave nanini na kunokwenzeka.
Masifunde nangekhemikhali ebizwa ngokuba yiPhthalates.
Ezinye iindaba ezimnandi zezokuba i-polypropylene ayinazo iikhemikhali ezibizwa ngokuba zii-phthalates.
Ii-phthalates zezinye iikhemikhali ezisetyenziselwa ukuthambisa iiplastiki, ezenza zibe bhetyebhetye kwaye zomelele. Kodwa ngoku uphando lufumanise ukuba ii-phthalates nazo ziyingozi kwimpilo yethu. Zingonakalisa inkqubo yethu ye-endocrine. Zifumaneka kuyo yonke into ukusuka kwilaphu letafile kunye nefenitshala ukuya kwiipakethe zokutya kunye nezinto zokuthambisa.
Ungachaphazeleka zii-phthalates ngezi ndlela zilandelayo:
- Ukufunxa ngokutya.
- Ngokuphefumla.
- Ngokusela amanzi angcolileyo.
- Ngokufunxwa ngumzimba ngesikhumba.
Ngoko ke, ngaba i-polypropylene inetyhefu ngokwenene?
I-Polypropylene ithathwa njengeplastiki ekhuselekileyo ukuyisebenzisa. Ivunyiwe naziiarhente ezifana ne-US Food and Drug Administration (FDA) ukuba isetyenziswe kube kanye kwaye isetyenziswe kwakhona kwizikhongozeli zokutya.
Akukho zifundo okwangoku ezibonisa unxibelelwano oluthe ngqo phakathi kwe-polypropylene nomhlaza ebantwini. Kodwa kukho into entsha ekufuneka siyiqwalasele apha. Kwaye loo nto yi -microplastics . Oko kukuthi, amasuntswana eplastiki amancinci kakhulu ukuba angabonwa ngamehlo enyama. Kusafuneka kwenziwe uphando oluninzi malunga nemiphumo yezi polypropylene microplastics emizimbeni yethu nakwindalo esingqongileyo.
Ziziphi iingenelo kunye neengxaki ze-polypropylene?
Xa kuthelekiswa neeplastiki ezineekhemikhali eziyingozi ezifana ne-BPA, i-polypropylene yeyona ndlela ilungileyo. Makhe sijonge iingenelo kunye neengxaki zayo eziphambili.
| Iinzuzo | Iingozi |
|---|---|
| Ubunzima obuphantsi. | Iba buthathaka lula xa amaqondo obushushu esezantsi kakhulu. |
| Uqinile, kodwa uguquguqukayo. | Iyaphela kancinci kancinci xa ibekwe elangeni. |
| Ixabiso lemveliso liphantsi. | Ayiboli xa yongezwa emhlabeni. |
| Ivunyiwe ukuba isetyenziswe ekutyeni. | Eyona ngozi inkulu: ii-microplastics . |
| Iyamelana nobushushu kwaye ihlala ixesha elide. | |
| Ingaphinda isetyenziswe. |
Eyona ngozi inkulu kwimpilo evela kwi-polypropylene ivela kwi-microplastics esixoxe ngazo ngaphambili. Ezi zincinci kangangokuba zinokungena emizimbeni yethu ngamanzi esiwaselayo nokutya esikutyayo. Uphononongo lwakutshanje lufumanise ukuba amasuntswana e-polypropylene angaqhelekanga anokuchaphazela ukukhula kweeseli zomhlaza wamabele zomntu kwaye anegalelo ekuqhubekeni komhlaza . Olu lolunye lwezifundo zokuqala ezibonisa indlela ii-microplastics ezichaphazela ngayo iiseli zomhlaza zomntu. Ukuba unemibuzo malunga noku, thetha nogqirha wakho.
Uyisebenzisa njani i-polypropylene ngokukhuselekileyo?
Ngokulandela le mithetho ilula, ungasebenzisa iimveliso ze-polypropylene ngokukhuselekileyo.
- Sebenzisa kuphela iimveliso zeplastiki ezinelebhile engena-BPA .
- Ungaze ufudumale ukutya kwiibhotile zeplastiki, ingakumbi kwi-microwave.
- Ukuba unezinto zeplastiki ezindala kunonyaka ka-2012 , zilahle, kuba ngokuqinisekileyo zinokuba ne-BPA.
- Musa ukusebenzisa kwakhona iibhotile zamanzi okanye ezinye izikhongozeli ezinekhowudi yokurisayikilisha inombolo 1. Zenzelwe ukusetyenziswa kube kanye kuphela.
- Musa ukuvumela umntwana wakho omncinci okanye isilwanyana sasekhaya sihlafune amathoyizi eplastiki.
Ngokubanzi, kukhuselekile ukusebenzisa izikhongozeli zeglasi endaweni yeplastiki nanini na xa kunokwenzeka ukugcina nokuphakela ukutya.
Umyalezo Wokuya Ekhaya
- I-Polypropylene (inombolo 5) lukhetho olukhuselekileyo kunezinye iintlobo ezininzi zeplastiki kuba ayinayo i-BPA kunye ne-phthalates.
- Kuphephe ukusebenzisa naluphi na uhlobo lweplastiki ukufudumeza ukutya. Iiglasi okanye izikhongozeli zeseramikhi zezona zilungele loo nto.
- Iiplastiki ezincinci zingumngcipheko okhulayo kwimpilo, ngoko ke kuyavakala ukunciphisa ukusetyenziswa kweplastiki kangangoko kunokwenzeka.
- Xa uthenga okanye usebenzisa imveliso yeplastiki, soloko ujonga ikhowudi yokurisayikilisha kuyo. Inombolo yesi-5 yipolypropylene.
