1. Menene fiber-based fiber?
● Fiber-based fibers na nufin zaruruwan da aka yi daga rayayyun halittu da kansu ko kuma abin da aka samu.Misali, fiber polylactic acid (PLA fiber) an yi shi ne da kayan amfanin gona masu ɗauke da sitaci kamar masara, alkama, da gwoza sugar, kuma fiber alginate an yi shi da algae mai launin ruwan kasa.
Irin wannan nau'in fiber na tushen halittu ba kawai kore ba ne kuma yana da alaƙa da muhalli, amma kuma yana da kyakkyawan aiki da ƙarin ƙima.Misali, kaddarorin inji, biodegradability, wearability, rashin flammability, abokiyar fata, maganin kashe kwayoyin cuta, da kaddarorin danshi na filayen PLA ba su da kasa da na filayen gargajiya.Alginate fiber shine babban kayan albarkatun kasa don samar da kayan gyare-gyaren likitanci sosai, don haka yana da ƙimar aikace-aikacen musamman a fannin likitanci da lafiya.
2. Me yasa ake gwada samfuran don abun ciki na biobased?
Kamar yadda masu amfani ke ƙara fifita abokantaka na muhalli, amintattu, samfuran kore masu tushen halittu.Bukatar fiber na tushen halittu a cikin kasuwar yadi yana karuwa kowace rana, kuma ya zama dole a samar da samfuran da ke amfani da adadi mai yawa na abubuwan da ke amfani da su don cin gajiyar masu fara farawa a kasuwa.Samfuran da suka dogara da halittu suna buƙatar abun ciki na samfurin ko yana cikin bincike da haɓakawa, sarrafa inganci ko matakan tallace-tallace.Gwajin biobased na iya taimakawa masana'anta, masu rarrabawa ko masu siyarwa:
● Samfuran R & D: Ana gudanar da gwaje-gwajen da aka yi amfani da su a cikin tsarin samar da samfurori na samfurori, wanda zai iya bayyana abubuwan da ke cikin samfurin don sauƙaƙe haɓakawa;
● Kulawa da inganci: A cikin tsarin samar da samfurori na tushen halittu, ana iya yin gwaje-gwaje na tushen halittu akan kayan da aka kawo don tabbatar da ingancin kayan albarkatun ƙasa;
● Ƙaddamarwa da tallace-tallace: Abubuwan da suka shafi halittu zasu zama kayan aiki mai kyau na tallace-tallace, wanda zai iya taimakawa samfurori su sami amincewar mabukaci da kuma amfani da damar kasuwa.
3. Ta yaya zan iya gano abubuwan da ke tushen halitta a cikin samfur?- Gwajin Carbon 14.
Gwajin Carbon-14 na iya bambanta daidaitattun abubuwan da suka samo asali da sinadarai da aka samu a cikin samfur.Saboda kwayoyin halitta na zamani sun ƙunshi carbon 14 daidai da adadin carbon 14 a cikin yanayi, yayin da albarkatun man petrochemical ba su ƙunshi wani carbon 14 ba.
Idan sakamakon gwajin da aka samo asali na samfurin shine abun cikin carbon na tushen 100%, yana nufin cewa samfurin ya samo asali 100%;idan sakamakon gwajin samfurin ya kasance 0%, yana nufin cewa samfurin duk sunadarai ne;idan sakamakon gwajin ya kasance 50%, yana nufin cewa kashi 50% na samfurin asalin halitta ne kuma 50% na carbon asalin petrochemical ne.
Matsayin gwaji don masaku sun haɗa da daidaitaccen ASTM D6866 na Amurka, ƙa'idodin Turai EN 16640, da sauransu.
