Ukukhetha ibhini yenkunkuma yeplastiki yangaphandle kubalulekile ukuqinisekisa ukuqina, ukusebenza kakuhle, kunye nobuhlobo nokusingqongileyo. Nokuba kukwiindawo zokuhlala, kwiindawo zorhwebo, kwiipaki, okanye kwiindawo zoshishino, ukhetho olufanelekileyo lunokuphucula ukusebenza kakuhle kokulahla inkunkuma, lunciphise iindleko zokulungisa, kwaye lugcine ucoceko lokusingqongileyo. Esi sikhokelo siza kuchaza izinto ezibalulekileyo ekufuneka ziqwalaselwe xa ukhetha iibhini zenkunkuma zeplastiki zangaphandle, kubandakanya ukukhethwa kwezinto, uyilo lohlu, kunye nokuthelekiswa kobungakanani, okukunceda wenze isigqibo esinolwazi.
Into ephambili 1: Ukukhethwa kwezinto – Isiseko sokuqina
Izinto ezisetyenziswa kwiibhotile zenkunkuma zeplastiki zangaphandle zimisela ngokuthe ngqo ixesha lokusebenza kwazo, ukusetyenziswa kwazo, kunye nokhuseleko lwazo. Izinto ezahlukeneyo zeplastiki zineempawu ezahlukileyo, ngoko ke kubalulekile ukuzifanisa neemeko ezithile zokusetyenziswa.
1. I-Polyethylene enoxinano oluphezulu (i-HDPE)
Njengesixhobo esisetyenziswa kakhulu, i-HDPE inobulukhuni obuphezulu, ukuqina okugqwesileyo, kunye nokumelana okunamandla nee-asidi kunye ne-alkalis. Ifanelekile ukugcina inkunkuma yasekhitshini, inkunkuma yasekhaya eqhelekileyo, kunye nezinye iintlobo zenkunkuma eqhelekileyo. Inzuzo ephawulekayo ye-HDPE kukuxhathisa kwayo kakuhle kubushushu obuphantsi, okuthintela ukuqhekeka nakwiindawo ezibandayo, okwenza ukuba ilungele ukusetyenziswa ngaphandle kwiindawo ezininzi.
2. I-Polypropylene (PP)
Izinto zePP zibonelela ngokumelana nobushushu obuphezulu xa kuthelekiswa neHDPE, ezikwaziyo ukumelana nobushushu obuphezulu. Oku kuyenza ifaneleke ngakumbi kwiindawo apho amanzi ashushu okanye inkunkuma enobushushu obuphezulu inokufumaneka khona, njengakwiindawo zokutyela, ii-canteens, okanye iindawo zokulungisa ukutya. Nangona kunjalo, kubalulekile ukuqaphela ukuba iPP inobunzima obuphantsi kancinci kumaqondo obushushu aphantsi, ngoko ke isenokungabi lolona khetho lufanelekileyo lokusetyenziswa ngaphandle kwiindawo ezibandayo kakhulu.
3. I-Polyvinyl Chloride (PVC)
I-PVC yinto yeplastiki engabizi kakhulu, kodwa ayizinzi kakuhle. Ingakhupha izinto ezinobungozi xa ibekwe kumaqondo obushushu aphezulu, nto leyo ebeka umngcipheko kwindalo esingqongileyo nakwimpilo yabantu. Okwangoku, i-PVC ayisetyenziswa rhoqo kwiimbiza zenkunkuma zangaphandle ezidibana ngqo nenkunkuma yasekhaya, kwaye ayikhuthazwa kwiimeko ezininzi zangaphandle.
Into ephambili 2: Uyilo loHlelo – Ngaphaya “kokuPhinda kusetyenziswe” kunye “nokunye”
Ngokuhambela phambili kwemigaqo-nkqubo yokwahlulahlula inkunkuma, iithini zenkunkuma zeplastiki zanamhlanje azisezizo nje izikhongozeli ezinkulu. Uyilo lwazo lokwahlulahlula luquka iimpawu ezicingisisiweyo ukuhlangabezana neemfuno ezahlukeneyo zokusetyenziswa kunye nokuphucula ukusebenza kakuhle kokuhlela inkunkuma.
1. Iindidi zeBhakethi ezimbini/Ibhakethi ezintathu
Olu lolona hlobo luqhelekileyo lokwahlulahlula. Iindidi eziqhelekileyo ziquka “Izinto Ezinokurisayikilishwa + Enye Inkunkuma” kunye “Nenkunkuma Yasekhitshini + Inkunkuma Eyingozi + Enye Inkunkuma.” Ezi bhokisi zenkunkuma zisebenzisa ikhowudi ecacileyo yombala (oluhlaza okwesibhakabhaka kwizinto ezinokurisayikilishwa, oluhlaza okwesibhakabhaka kwinkunkuma yasekhitshini, obomvu kwinkunkuma enobungozi, ongwevu kwenye inkunkuma, njl.njl.), okuvumela uluntu ukuba luchonge kwaye luhlele inkunkuma ngokuchanekileyo ngokulula.
2. Uyilo oluneZivalo
Iingqayi zenkunkuma ezinezivalo zisebenza kakuhle ekuvaleni, nto leyo enokunciphisa ngempumelelo ukusasazeka kwevumba. Zikwathintela amanzi emvula ukuba angangeni ebhakethini kwaye zithintele ukuzala kweengcongconi neempukane, nto leyo ezenza zifaneleke ngakumbi ukugcina inkunkuma yasekhitshini okanye ukusetyenziswa kwiindawo ezifumileyo zangaphandle.
3. Ukuvulwa kwesiciko esisebenza ngeenyawo
Uyilo olusetyenziswa ngeenyawo luvumela abasebenzisi ukuba bavule isiciko ngaphandle kokusichukumisa ngezandla zabo, nto leyo ephucula kakhulu ucoceko. Olu hlobo lwenkunkuma lusetyenziswa kakhulu kwiindawo zikawonke-wonke ezineemfuno eziphezulu zococeko, ezifana nezibhedlele, iivenkile ezinkulu, kunye nezikolo zabantwana abancinci.
4. Iibhakethi eziDityanisiweyo ezinomthamo omkhulu
Ixhaphake kakhulu kwiindawo ezinabantu abaninzi ezifana nezikwere, iindawo ezintle, kunye namabala emidlalo, iibhakethi ezininzi zidibene. Olu yilo alugcini nje ngokugcina ulwahlulo olucacileyo kodwa lukwagcina indawo, luququzelela ukuqokelelwa kunye nokuthuthwa ngabasebenzi bococeko.
Into ephambili 3: Ukulinganisa ubungakanani – Khetha ngokusekwe kwiSimo sesicelo
Ubungakanani beeplastiki ezingaphandle buchaphazela ngqo ukusebenza kwazo kunye nokusetyenziswa kwendawo. Ukukhetha ubungakanani obufanelekileyo ngokwemeko yokusetyenziswa kunokuthintela iingxaki ezinjengokungoneli komthamo okanye ukuhlala kakhulu kwendawo.
1. IiNdlela zoLuntu/Iindlela zokungena kwiYunithi
Iimbiza zenkunkuma ezincinci ezinamabhakede amabini ezinomthamo weelitha ezingama-30-50 zifanelekile apha. Zincinci kwaye azithathi ndawo ingako, nto leyo eyenza kube lula kubahlali ukulahla inkunkuma yemihla ngemihla.
2. Izitalato/Iindlela zePaki
Kucetyiswa ukuba kusetyenziswe iimbiza zenkunkuma eziphakathi ezinomthamo weelitha ezingama-80-120. Umthamo wazo uphakathi, nto leyo enokwanelisa iimfuno zokulahla inkunkuma zabahambi ngeenyawo nangona zingekho zikhulu kakhulu ukuba zingachaphazela ubuhle bendalo.
3. Izikwere/Iindawo Ezintle/Iindawo Zokudlala Zesikolo
Iindawo ezinabantu abaninzi zifuna ii-inki zenkunkuma ezinomthamo omkhulu weelitha ezili-150-240. Oku kunokunciphisa ukuqokelelwa nokuthuthwa kwenkunkuma kwaye kuthintele inkunkuma ukuba ingakhuphi.
Ukuze ukhethe itini yenkunkuma yeplastiki yangaphandle efanelekileyo, kufuneka uqwalasele ngokupheleleyo izinto ezintathu eziphambili: izinto, uyilo lokwahlulahlula, kunye nobukhulu. Beka phambili izinto zeHDPE okanye zePP ngokusekelwe kwindalo esingqongileyo; khetha uyilo olufanelekileyo lokwahlulahlula ngokweemfuno zokwahlulahlula inkunkuma kunye nemigangatho yococeko; kwaye ulungelelanise ubungakanani nomthamo wezithuthi kunye neemeko zendawo yokusetyenziswa. Ngokulandela le migaqo, ungakhetha itini yenkunkuma ehlala ixesha elide, esebenzayo, kwaye enobuhlobo nokusingqongileyo, idale imeko-bume yangaphandle ecocekileyo necwangcisiweyo.
