1. Kedu ihe bụ eriri bio-based?
● Fiber dabeere n’ihe ndị dị ndụ na-ezo aka n’eriri e si na ihe ndị dị ndụ n’onwe ha mee ma ọ bụ ihe ndị ha amịpụtara.Dịka ọmụmaatụ, fiber polylactic acid (PLA fiber) bụ nke ngwaahịa ugbo nwere starch dị ka ọka, ọka wit, na beet sugar, na alginate fiber bụ nke algae na-acha aja aja.
● Ụdị eriri nke dabeere na bio abụghị nanị akwụkwọ ndụ akwụkwọ ndụ na gburugburu ebe obibi, kamakwa ọ na-arụ ọrụ magburu onwe ya yana uru ka ukwuu.Dịka ọmụmaatụ, ihe eji arụ ọrụ, biodegradability, wearability, non-flammability, enyi na enyi akpụkpọ ahụ, antibacterial, na mmiri mmiri nke eriri PLA adịghị ala karịa nke eriri ọdịnala.Alginate fiber bụ akụrụngwa akụrụngwa dị elu maka imepụta akwa mkpuchi ahụike hygroscopic nke ukwuu, yabụ na ọ nwere uru ngwa pụrụ iche na ngalaba ahụike na ahụike.
2. Gịnị kpatara nwalee ngwaahịa maka ọdịnaya biobased?
Ka ndị na-azụ ahịa na-enwetawanye mmasị na gburugburu ebe obibi, nchekwa, ngwaahịa ndụ ndụ sitere na bio.Ọchịchọ maka fibers sitere na bio na ahịa akwa na-abawanye kwa ụbọchị, ọ dịkwa mkpa ịmepụta ngwaahịa ndị na-eji oke ihe dabere na bio iji nweta uru mbụ na-ebubata n'ahịa ahụ.Ngwaahịa dabere na bio chọrọ ọdịnaya dabere na bio nke ngwaahịa ma ọ dị na nyocha na mmepe, njikwa mma ma ọ bụ ọkwa ire ahịa.Nnwale biobased nwere ike inyere ndị nrụpụta, ndị nkesa ma ọ bụ ndị na-ere ahịa aka:
● Ngwaahịa R & D: A na-eme nyocha nke bio na usoro nke mmepụta ihe na-emepụta ihe na-emepụta ihe, nke nwere ike dokwuo anya ọdịnaya nke bio-based na ngwaahịa ahụ iji kwado nkwalite;
● njikwa mma: N'ime usoro mmepụta nke ngwaahịa ndị dabeere na bio, enwere ike ịme ule na-adabere na ihe ndị a na-enye maka ijikwa ike nke ngwaahịa ngwaahịa;
● Nkwalite na ire ahịa: Ọdịnaya dabeere na bio ga-abụ ezigbo ngwá ahịa ahịa, nke nwere ike inyere ngwaahịa aka inweta ntụkwasị obi nke ndị ahịa na iji ohere ahịa.
3. Kedu otu m ga-esi mata ọdịnaya biobased na ngwaahịa?– Carbon 14 ule.
Nnwale Carbon-14 nwere ike ịwapụta nke ọma ihe dabere na bio na petrochemical na ngwaahịa.N'ihi na ihe ndị dị n'oge a nwere carbon 14 n'otu ego dị na carbon 14 na ikuku, ebe akụrụngwa petrochemical enweghị carbon 14 ọ bụla.
Ọ bụrụ na nsonaazụ nnwale bio dabere na ngwaahịa bụ 100% ọdịnaya carbon bio, ọ pụtara na ngwaahịa a sitere na 100% bio;Ọ bụrụ na nsonaazụ nke ngwaahịa bụ 0%, ọ pụtara na ngwaahịa ahụ bụ petrochemical niile;Ọ bụrụ na nsonaazụ nnwale ahụ bụ 50%, ọ pụtara na 50% nke ngwaahịa sitere na ndu ndu yana 50% nke carbon sitere na petrochemical.
Ụkpụrụ ule maka akwa akwa gụnyere ọkọlọtọ American ASTM D6866, European ọkọlọtọ EN 16640, wdg.
