1. Yintoni ifayibha esekwe kwibhayoloji?
● Iifayibha ezisekelwe kwi-bio zibhekisa kwiifayibha ezenziwe ngezinto eziphilayo ngokwazo okanye kwiimveliso zazo. Umzekelo, ifayibha ye-polylactic acid (i-PLA fiber) yenziwe ngeemveliso zezolimo eziqulethe istatshi ezifana nombona, ingqolowa, kunye ne-sugar beet, kwaye ifayibha ye-alginate yenziwe nge-algae emdaka.
● Olu hlobo lwefayibha esekwe kwi-bio alugcini nje ngokuba luhlaza kwaye lunobuhlobo nokusingqongileyo, kodwa lukwasebenza kakuhle kwaye lunexabiso elongezelelekileyo. Umzekelo, iipropati zoomatshini, ukubola kwe-biograd, ukuguguleka, ukungatshi, ulusu olunobuhlobo, iintsholongwane, kunye neempawu zokususa umswakama zeefayibha ze-PLA azikho ngaphantsi kwezo zeefayibha zemveli. Ifayibha ye-alginate sisixhobo esiluhlaza esisemgangathweni ophezulu sokwenza ii-dressings zonyango ezithambileyo kakhulu, ngoko ke sinexabiso elikhethekileyo lokusetyenziswa kwicandelo lezonyango nakwimpilo.
2. Kutheni kufuneka uvavanye iimveliso ukuze ubone umxholo webhayoloji?
Njengoko abathengi besiya bekhetha iimveliso eziluhlaza ezinobuhlobo nokusingqongileyo, ezikhuselekileyo, nezivela kwindalo. Imfuno yeefayibha ezisekelwe kwindalo kwimarike yelaphu iyanda imihla ngemihla, kwaye kubalulekile ukuphuhlisa iimveliso ezisebenzisa inani elikhulu lezinto ezisekelwe kwindalo ukuze zifumane inzuzo yokuqala kwimarike. Iimveliso ezisekelwe kwindalo zifuna umxholo osekelwe kwindalo kwimveliso nokuba isekwinqanaba lophando nophuhliso, ulawulo lomgangatho okanye ukuthengisa. Uvavanyo olusekelwe kwindalo lunokunceda abavelisi, abasasazi okanye abathengisi:
● Uphando noPhuhliso lweMveliso: Uvavanyo olusekelwe kwi-bio lwenziwa kwinkqubo yophuhliso lwemveliso olusekelwe kwi-bio, olunokucacisa umxholo osekelwe kwi-bio kwimveliso ukuze kube lula ukuphucula;
● Ulawulo lomgangatho: Kwinkqubo yokuvelisa iimveliso ezisekelwe kwibhayoloji, uvavanyo olusekelwe kwibhayoloji lunokwenziwa kwizixhobo ezisetyenzisiweyo ukulawula ngokungqongqo umgangatho wezixhobo ezisetyenzisiweyo kwimveliso;
● Ukukhuthaza nokuthengisa: Umxholo osekelwe kwi-bio uza kuba sisixhobo esihle kakhulu sokuthengisa, esinokunceda iimveliso zifumane ukuthenjwa ngabathengi kwaye zithathe amathuba emarike.
3. Ndingawubona njani umxholo osekelwe kwibhayoloji kwimveliso? – Uvavanyo lweCarbon 14.
Uvavanyo lwe-Carbon-14 lunokwahlula ngempumelelo izinto ezisekelwe kwi-bio-based kunye ne-petrochemical kwimveliso. Kuba izinto eziphilayo zanamhlanje ziqulethe i-carbon 14 ngomlinganiselo ofanayo ne-carbon 14 emoyeni, ngelixa izinto ezikrwada ze-petrochemical zingenazo naziphi na ii-carbon 14.
Ukuba iziphumo zovavanyo olusekelwe kwibhayoloji zemveliso ziyi-100% yomxholo wekhabhoni osekelwe kwibhayoloji, oko kuthetha ukuba imveliso ifunyenwe kwi-100% yendalo; ukuba iziphumo zovavanyo lwemveliso ziyi-0%, oko kuthetha ukuba imveliso yonke iyi-petrochemical; ukuba iziphumo zovavanyo ziyi-50%, oko kuthetha ukuba i-50% yemveliso ivela kwibhayoloji kwaye i-50% yekhabhoni ivela kwi-petrochemical.
Imigangatho yovavanyo lwempahla ibandakanya umgangatho waseMelika i-ASTM D6866, umgangatho waseYurophu i-EN 16640, njl.
