Nke a na-ewetara gị nghọta miri emi nke akpa nkwakọ ngwaahịa ndị nwere ike imebi emebi!
Ka ọtụtụ mba na-amachibido akpa plastik, a na-eji akpa plastik eme ihe n'ọtụtụ ụlọ ọrụ. Ichekwa gburugburu ebe obibi bụ ihe a na-apụghị izere ezere. Enwere ebe ọ bụla na-akwado iji akpa plastik nwere ike ire ere? Kedu ngwaahịa enwere ike iji akpa plastik nwere ike ire ere? Ekwenyere m na nke a bụ ihe ọtụtụ ndị ahịa na-enye iwu maka akpa plastik nwere ike ire ere zuru oke chọrọ ịma. Taa, OK Nkwakọ ngwaahịa nke akpa plastik nwere ike ire ere na-achọ ịma.
1. Gịnị bụ nkwakọ ngwaahịa nwere ike imebi emebi?
Akpa plastik a na-ere ere bụ ụdị akpa plastik nke nwere ike imebi mmiri, carbon dioxide na obere molekul ndị ọzọ kpamkpam. Isi ihe dị na ihe a na-ere ere bụ polylactic acid (PLA), nke a na-esi na ọka na aki apụta. Planet (PLA) bụ ụdị ihe ọhụrụ dabere na bio na ihe a na-ere ere emeghari. Mgbe a gbasịrị glucose na ụfọdụ ụdị iji mepụta lactic acid dị ọcha, a na-emepụta poly (lactic acid) nwere oke molekul ụfọdụ site na usoro kemịkalụ, wee nweta glucose site na saccharification. Ngwaahịa a nwere ezigbo mmebi bio, enwere ike imebi ya kpamkpam site na obere nje eke mgbe ejiri ya mepụta carbon dioxide na mmiri, nke agaghị emerụ gburugburu ebe obibi mgbe ejiri ya. Ọ bara ezigbo uru maka nchekwa gburugburu ebe obibi ma a na-ewere ya dị ka ihe na-adịghị emebi gburugburu ebe obibi.
Ugbu a, ihe dị mkpa nke akpa plastik ndị a na-ere ere bụ PLA + PBAT, nke enwere ike ịgbaze kpamkpam ka ọ bụrụ mmiri na carbon dioxide n'ime ọnwa 3-6 n'okpuru ọnọdụ nke ịgbaze (ogo 60-70). Enweghị mmetọ na gburugburu ebe obibi. Gịnị mere a ga-eji tinye PBAT? PBAT bụ copolymer nke adipic acid, 1, 4-butanediol na terephthalic acid, nke bụ aliphatic na aromatic polymer nke kemịkalụ mepụtara kpamkpam. PBAT nwere mgbanwe dị mma ma enwere ike iji ya maka mmịpụta ihe nkiri, ịkpụzi ihe, mkpuchi extrusion na usoro ịkpụzi ndị ọzọ. Emebere ngwakọta nke PLA na PBAT iji melite ike, ịgbaze ihe na nhazi nke PLA.
2. Ebee ka ndị na-emepụta akpa ndị nwere ike imebi emebi nọ, ndị nwere aha ọma?
N'ihe gbasara akpa plastik ndị a na-ere ere, o mepụtala igwe pụrụ iche nke na-afụ ihe nkiri, igwe obibi akwụkwọ, igwe ịkpụ akpa, ihe na-emegharị ihe mkpofu na ọtụtụ ahịrị mmepụta tozuru oke maka akpa plastik ndị a na-ere ere ...
Nkwakọ ngwaahịa dị mma na-agbaso echiche nke nchekwa gburugburu ebe obibi ma na-agba mbọ maka mmepe na-adịgide adịgide nke gburugburu ebe obibi, nke e mepụtara nke ọma dabara adaba maka ụlọ ọrụ nkwakọ ngwaahịa na inye nri ihe eji eme nri na ngwaahịa zuru oke, nwere ahụmịhe bara ụba na ụlọ ọrụ nkwakọ ngwaahịa ma na-aza nhazi ihe mkpofu, na-akwalite iji akụrụngwa eme ihe, ma na-emepụta ngwaahịa ndị nwere ike ire ere nke ọma na ọkwa nri.
3. Kedu ngwaahịa enwere ike iji akpa ndị nwere ike ire ere mee ihe?
A na-ejikarị akpa plastik ndị a na-ere ere eme ihe n'uwe elu, ịkpa ákwà, uwe, ákwà, nri, ngwaike, ngwa eletrọnịkị, ihe ịchọ mma na ụlọ ọrụ ndị ọzọ. Akpa plastik ndị a na-ere ere nwere ọtụtụ ihe e ji eme mkpuchi, dị ka ọkpụkpụ na-arapara, zipa, teepu, wdg, akpa plastik ndị a na-ere ere na-ejikọta ya na akwụkwọ, nke nwere ike ịpịa akụkụ ala. Ugbu a, akpa plastik ndị a na-ere ere na-abanye n'akụkụ niile nke ndụ, e nwekwara ụdị dị iche iche; N'ọdịnihu, akpa plastik ndị a na-ere ere ga-aghọ ngwaahịa zuru oke nke ụlọ ọrụ nkwakọ ngwaahịa.
