Ityaleti yonke yiinto esingazangeleka eyenza kuvumela sifundze kakhulu kwezinto ezindala zethu. Ungaqhuba ngokwesikhatsi ngaphandle komuntu obheke ukuthi zinto zingabe lapho ziyiphakamisiwe? Lolu hlangothi lwakuxhasa sizofunda nge-PP, PE, kunye ne-HDPE - umoya omtsha we-3 wetyaleti. Le nto akufuneki ukuba isebentle kunye nokuba igama eliloliyentombazana, kodwa lokhu kungaba yonke lezi zityaleti zezimpilo!
PP() Lolu hlobo lesi plastic elikhulu kakhulu okwesibhedlela umoya wempi lokugcina. しぶりのでち? PP (polypropylene) PP: polypropylene Uyaziyo amagama emihlaba ngaphandle kokuthi uzoba ukuphakamisa i-soup enguqulayo (ayiphatheka). Kulokhu PP kukhethwe kwindawo eziningi, kwisebe eside samalimi kubantu kunye nezicaphe zebhoteli kunye nokuningi okungavunyelwa ngalo lona kuhloniphe izindlu zokukhula. Umthwalo omncane weplastic, ngoba uzobuyiselisa imifuno yethu kuziphathelene.
Ngaphandle, ukuhlala kwethu ni-PE, engasebenzisa polyethylene. Ngokushesha kwe-PP, i-PE yiya ngaphansi kunye nokuhlola. Le nto obucabanga phambili emibhalweni yamabhedi eziphakeme noma ubuchabalashe obuzoba ukusetyenziswa ukuvula amacola angaphandle kune-PE! Kuna hlobo lokuhlola, kunjalo ayiqhagamshini. I-PE isebenza thukuthe nge-amabhendi wamanzi, amabhedi amancamane kunye nobuchabalashe lobucabanga. Phikisana naye njengeyindoda osebenza: ungakwazi ukufakwa kunye nokulinda izinto.
i-HDPE (high-density polyethylene) yehlukileyo lomusha wendawo. Lolu hlobo lwemusha nalo manje kungapheliwe ngokuthi lokhu kunene ukusuka emanzini okunye nokuhlola amandla, kunye nokuhlola izinto ezincane ezinamandla. i-HDPE liyisebenzisi kwi-pipes, intanki ezingasihlanu kunye nezi-trash can. Kuneziphi zintando ezifanele ukuba zikhuphe ngalokho olungaphansi kakhulu. Ungavuma i-HDPE njenge-pipe elithumela amanzi, kodwa alibonekelayo, noma i-trash can engakwenzekayo ukwakha phandle komhlabathi okanye umvula.
Yilomusha olungayiphiwa ukuba siphumelele into eyona sibonisa kulesi sizuku. Kwesikhashana sesentombini esingazibiza kutsi kubuyekezwe kwi-toys esingazibiza ngenqanawe kunye ne-bottles esingahluhluhlayo, leso special plastics sihlala phambi konina. Baye abasebenzisi abangaphambili babenziwe ukuba baphumelele amagaba apha ahlukene, asiphathelene kunye nabafundiswa. Izifirma zikama Yuezheng zibenziwe ukuba ziphumelele leso special plastics kunye nokuba zisihlanganise kwi-utshwala olusebenzisekile.
Lokhu olunyezwe ngamaxesha aphantsi abafundi ukuthi lokho lezi zityaleti zikhethela yini lapho kufanele izinto ezidingiswa. Bakhetha into esithile? Okanye bakhetha into engakwazi ukugcina? Ngiyayazi noma ashiyene ziyo zityaleti ezizoba kuphela ezingqaneni noma ezinkulu? Izityaleti zihlukahluka ngemibono, ngenxa yalokho kulokhu kuhlanganiswa.
Zingasinye izityaleti ezinjalo zikuphumelela ukungena amacababi kunye nokuba zingasinye zikuphumelela ukubuyisela iibegi kunye nokuba zingasinye zikuphumelela ukusetyenziswa kwiintshukumo ezidingekayo ukuba zingathile. Funa ukubona njengomsebenzi wendaba, ungene ngeenkcukacha ezininzi, kodwa ungakwazi ukuhlola umsebenzi ngenkxaso elilonke, yeyiphi inkxaso ingeziselela ngalokhu ifaka lokhu kufuneka kube ngalo.
