1. Iyini i-fiber esuselwe ku-bio?
● Imicu esuselwe ku-bio ibhekisela kumicu eyenziwe ngezinto eziphilayo ngokwazo noma ezikhishwe kuzo. Isibonelo, i-polylactic acid fiber (i-PLA fiber) yenziwe ngemikhiqizo yezolimo equkethe isitashi njengommbila, ukolweni, kanye ne-sugar beet, kanti i-alginate fiber yenziwe nge-algae ensundu.
● Lolu hlobo lwefayibha esuselwe ku-bio alugcini nje ngokuba luhlaza futhi lunobungani nemvelo, kodwa futhi lusebenza kahle kakhulu kanye nenani elengeziwe. Isibonelo, izakhiwo zemishini, ukubola, ukuguguleka, ukungashi, ukungabi nomswakama kwesikhumba, ukulwa namagciwane, kanye nezakhiwo zokususa umswakama zefayibha ze-PLA aziphansi kunezo zefayibha zendabuko. Ifayibha ye-alginate iyinto eluhlaza esezingeni eliphezulu yokukhiqiza izingubo zezokwelapha ezi-hygroscopic kakhulu, ngakho-ke inenani elikhethekile lokusetshenziswa emkhakheni wezokwelapha kanye nezempilo.
2. Kungani uhlola imikhiqizo ukuze uthole okuqukethwe okusekelwe ku-bio?
Njengoba abathengi beqhubeka bethanda imikhiqizo eluhlaza enobungani nemvelo, ephephile, nevela ezintweni eziphilayo. Isidingo semicu esuselwa ezintweni eziphilayo emakethe yezindwangu siyakhula usuku nosuku, futhi kubalulekile ukuthuthukisa imikhiqizo esebenzisa ingxenye enkulu yezinto ezisuselwa ezintweni eziphilayo ukuze kutholakale inzuzo yokuqala emakethe. Imikhiqizo esuselwa ezintweni eziphilayo idinga okuqukethwe okusekelwe ezintweni eziphilayo komkhiqizo kungakhathaliseki ukuthi kusesigabeni socwaningo nokuthuthukiswa, ukulawulwa kwekhwalithi noma ukuthengiswa. Ukuhlolwa okusekelwe ezintweni eziphilayo kungasiza abakhiqizi, abasabalalisi noma abathengisi:
● Ucwaningo Nokuthuthukiswa Komkhiqizo: Ukuhlolwa okusekelwe ku-bio kwenziwa enkambisweni yokuthuthukiswa komkhiqizo osekelwe ku-bio, okungacacisa okuqukethwe okusekelwe ku-bio kumkhiqizo ukuze kube lula ukuthuthuka;
● Ukulawulwa kwekhwalithi: Enqubweni yokukhiqizwa kwemikhiqizo esuselwe ku-bio, ukuhlolwa okususelwe ku-bio kungenziwa ezintweni zokusetshenziswa ezinikeziwe ukuze kulawulwe ngokuqinile ikhwalithi yezinto zokusetshenziswa zomkhiqizo;
● Ukukhushulwa nokumaketha: Okuqukethwe okusekelwe ku-bio kuzoba ithuluzi elihle kakhulu lokumaketha, elingasiza imikhiqizo ukuthi ithole ukwethenjwa ngabathengi futhi ibambe amathuba emakethe.
3. Ngingakubona kanjani okuqukethwe okusekelwe ku-bio kumkhiqizo? – Ukuhlolwa kwe-Carbon 14.
Ukuhlolwa kwe-Carbon-14 kungahlukanisa ngempumelelo izingxenye ezisuselwa ku-bio kanye ne-petrochemical kumkhiqizo. Ngoba izinto eziphilayo zanamuhla ziqukethe i-carbon 14 ngenani elifanayo ne-carbon 14 emkhathini, kuyilapho izinto zokusetshenziswa kwe-petrochemical zingenawo noma iyiphi i-carbon 14.
Uma umphumela wokuhlolwa okusekelwe ku-bio womkhiqizo ungu-100% wokuqukethwe kwekhabhoni okusekelwe ku-bio, kusho ukuthi umkhiqizo uvela ku-100% ku-bio; uma umphumela wokuhlolwa komkhiqizo ungu-0%, kusho ukuthi umkhiqizo wonke ungowe-petrochemical; uma umphumela wokuhlolwa ungu-50%, kusho ukuthi u-50% womkhiqizo uvela ku-bio kanti u-50% wekhabhoni uvela ku-petrochemical.
Izindinganiso zokuhlola zezindwangu zifaka phakathi izinga laseMelika i-ASTM D6866, izinga laseYurophu i-EN 16640, njll.
