Uma kukhulunywa ngezikhwama zegrosa ezisebenziseka kabusha, ziningi izinketho ezikhona ezingase zibonakale zingaphezu kwamandla.Kufanele ucabangele ukuthi iyiphi ekulungele: Ingabe udinga into encane futhi ehlangene ukuze ukwazi ukuyiphatha yonke indawo?Noma, udinga into enkulu futhi eqinile ohambweni lwakho olukhulu lwegrosa lwamasonto onke?
Kodwa futhi ungahle ucabange, "Ngempela lesi sikhwama senziwe ngani?"Izikhwama ezihlukene ezingasetshenziswa kabusha zenziwe ngezinto ezahlukene, futhi ngenxa yalokho, ezinye zinobungani bemvelo kunezinye.Ngakho-ke ungase futhi ucabange, "Ingabe isikhwama sikakotini sisimama kakhulu kunesikhwama se-polyester?"Noma, “Ingabe isikhwama sepulasitiki esiqinile engifuna ukusithenga singcono kakhulu kunesikhwama segrosa sepulasitiki?”
Izikhwama ezisebenziseka kabusha, kungakhathaliseki ukuthi ziyini izinto ezibonakalayo, zizodala umthelela omncane kwezemvelo kunamanani amaningi ezikhwama zepulasitiki ezisetshenziswa kanye ezingena endaweni nsuku zonke.Kodwa umehluko womthelela empeleni uyamangaza.
Kungakhathaliseki ukuthi hlobo luni, kubalulekile ukukhumbula ukuthi lezi zikhwama azihloselwe ukusetshenziswa kanye.Lapho uzisebenzisa izikhathi eziningi, yilapho ziba nobungane kakhulu nemvelo.
Sihlanganise uhlu olungezansi lwendwangu ehlukahlukene nezinto ezisetshenziswa kakhulu ukukhiqiza izikhwama ezisebenziseka kabusha.Uzokwazi ukunquma ukuthi yiziphi izikhwama ezenziwe ngezinto zokwakha kanye nomthelela wemvelo wohlobo ngalunye.
Imicu Yemvelo
Izikhwama zeJute
Inketho enhle, yemvelo uma kuziwa ezikhwameni ezingasetshenziswa kabusha yisikhwama se-jute.I-Jute ingenye yezindlela ezimbalwa ezingasetshenziswa esikhundleni sepulasitiki engaboli ngokuphelele futhi enomthelela ophansi kwezemvelo.I-Jute iyinto ephilayo etshalwa futhi itshalwe eNdiya naseBangladesh.
Lesi sitshalo sidinga amanzi amancane ukuze sikhule, singakhula futhi empeleni sibuyisele indawo engenalutho, futhi sinciphise inani elikhulu le-CO2 ngenxa yezinga laso lokuhlanganisa i-carbon dioxide.Iqinile futhi ngokwedlulele futhi ishibhile ukuyithenga.Okubi kuphela ukuthi ayikwazi ukumelana namanzi ngendlela yayo yemvelo.
Izikhwama zikakotini
Enye inketho yisikhwama sekotini yendabuko.Izikhwama zikakotini ziyindlela evamile engasetshenziswa kabusha kunezikhwama zepulasitiki.Ayisindi, ayapakishwa, futhi angasiza ekusetshenzisweni okuhlukahlukene.Futhi zinamandla okuba yi-100% yezinto eziphilayo, futhi ziyabola.
Nokho, ngenxa yokuthi ukotini udinga izinsiza eziningi ukuze ukhule futhi ulinywe, kufanele usetshenziswe okungenani izikhathi ezingu-131 ukuze udlule umthelela wawo endaweni ezungezile.
Ama-Synthetic Fibers
Izikhwama zePolypropylene (PP).
Izikhwama ze-polypropylene, noma izikhwama ze-PP, yizikhwama ozibona ezitolo zegrosa eduze kwasesiqhingini sokuphuma.Ziyizikhwama zepulasitiki ezisebenza kabusha ezihlala isikhathi eside ezidizayinelwe ukusetshenziswa okuningi.Zingenziwa kusuka kokubili okungezona nokwelukiweyo kwe-polypropylene futhi ziza ngemibala ehlukahlukene nobukhulu.
Nakuba lezi zikhwama zingavundisi noma zibola, ziyizikhwama ezisebenza kahle kakhulu emvelweni uma kuqhathaniswa nezikhwama zegrosa ze-HDPE zendabuko.Ngokusetshenziswa okungu-14 nje, izikhwama ze-PP ziba ne-eco-friendly kunezikhwama zepulasitiki ezisetshenziswa kanye.Futhi banamandla okwenziwa ngezinto ezigaywe kabusha.
Izikhwama ze-PET ezigaywe kabusha
Izikhwama ze-PET ezigaywe kabusha, ngokungafani nezikhwama ze-PP, zenziwe kuphela nge-polyethylene terephthalate (PET) noma amabhodlela amanzi agaywe kabusha neziqukathi.Lezi zikhwama, nakuba zenziwe ngepulasitiki, zisebenzisa imfucumfucu engadingekile evela emabhodleleni amanzi epulasitiki futhi zikhiqiza umkhiqizo ogaywe kabusha futhi owusizo.
Izikhwama ze-PET zipakisha ezansi zazo ezincane futhi zingasetshenziswa iminyaka.Ziqinile, zihlala isikhathi eside, futhi ngokombono wensiza, zinendawo ephansi kakhulu yezemvelo ngoba zisebenzisa udoti olahlwayo.
I-polyester
Izikhwama eziningi ezinemfashini nezinemibala zenziwe nge-polyester.Ngeshwa, ngokungafani nezikhwama ze-PET ezigaywe kabusha, i-polyester emsulwa idinga imiphongolo kawoyela ongahluziwe ecishe ibe yizigidi ezingama-70 unyaka ngamunye ukuze ikhiqize.
Kodwa ohlangothini oluhle, isikhwama ngasinye sidala kuphela amagremu angu-89 esisi esingcolisa umoya, esilingana nezikhwama eziyisikhombisa ze-HDPE ezisetshenziswa kanyekanye.Izikhwama ze-polyester nazo azikwazi ukushwabana, zimelana namanzi, futhi zingagoqeka kalula ukuze zize nawe yonke indawo.
Inayiloni
Izikhwama zenayiloni zingenye inketho yesikhwama esiphinde isetshenziswe kalula.Nokho, inayiloni yenziwe ngamakhemikhali e-petrochemical kanye ne-thermoplastic—empeleni idinga amandla aphindwe kabili ukuze ikhiqize kunokotini namafutha angcolile ukuze ikhiqize kune-polyester.
Kunezinketho eziningi ongakhetha kuzo, kodwa lokho akusho ukuthi ukukhetha isikhwama esisebenziseka kabusha kufanele kudide.Njengoba kushiwo ngaphambili, uma usebenzisa isikhwama izikhathi eziningi, kuba yilapho sihambisana nemvelo;ngakho kubalulekile ukuthola isikhwama evumelana nezidingo zakho siqu.
