Nke a na-ewetara gị nghọta miri emi nke akpa nkwakọ ngwaahịa biodegradable!
Ka ọtụtụ mba na-amachibido akpa rọba, a na-eji akpa nwere ike ime ihe n'ọtụtụ ụlọ ọrụ. Ichebe gburugburu ebe obibi bụ ihe a na-apụghị izere ezere. Enwere isi mmalite ọ bụla na-akwado iji akpa rọba na-emebi emebi? Kedu ngwaahịa a ga-eji akpa rọba na-emebi emebi? Ekwenyere m na nke a bụ ihe ọtụtụ ndị ahịa na-enye iwu chọrọ akpa rọba na-emebi emebi chọrọ ịma. Taa, OK nkwakọ ngwaahịa nke akpa rọba na-emebi emebi
1. Gịnị bụ nkwakọ ngwaahịa biodegradable?
Akpa rọba nwere ike imebi bụ ụdị akpa rọba nke nwere ike imebi mmiri, carbon dioxide na obere ụmụ irighiri ihe ndị ọzọ kpamkpam. Isi ebe ihe a na-emebi emebi bụ polylactic acid (PLA), nke a na-amịpụta na ọka na akpụ. Planet (PLA) bụ ụdị ihe ọhụrụ dabere na bio na ihe enwere ike imegharịgharị. Mgbe agbachara glucose na ụfọdụ ụdị iji mepụta lactic acid dị ọcha, a na-emepụta poly (lactic acid) nwere ụfọdụ ịdị arọ molekul site na usoro njikọ kemịkalụ, wee nweta glucose site na saccharification. Ngwaahịa a nwere ezigbo biodegradability na enwere ike imebi ya kpamkpam site na microorganisms eke mgbe ejiri ya mepụta carbon dioxide na mmiri, nke na-agaghị emetọ gburugburu ebe obibi mgbe ejiri ya. Ọ bara ezigbo uru na nchekwa gburugburu ebe obibi ma na-ewere ya dị ka ihe na-emetụta gburugburu ebe obibi.
Ka ọ dị ugbu a, isi ihe dị ndụ nke akpa rọba na-emebi emebi bụ PLA + PBAT, nke nwere ike imebi kpamkpam n'ime mmiri na carbon dioxide n'ime ọnwa 3-6 n'okpuru ọnọdụ composting (ogo 60-70). Enweghị mmetọ na gburugburu ebe obibi. Gịnị kpatara tinye PBAT? PBAT bụ copolymer nke adipic acid, 1, 4-butanediol na terephthalic acid, nke bụ ihe na-eme ka aliphatic na aromatic polymer mejupụta kpamkpam. PBAT nwere ezigbo mgbanwe na enwere ike iji ya mee ihe maka extrusion ihe nkiri, ịfụ ụfụ, mkpuchi extrusion na usoro nhazi ndị ọzọ. A haziri ngwakọta nke PLA na PBAT iji melite ike, biodegradability na formability nke PLA.
2. Ebee ka ndị na-emepụta akpa biodegradable nwere aha ọma dị?
N'ihe gbasara akpa rọba na-emebi emebi, ọ kpụrụla igwe na-akụ ihe nkiri pụrụ iche, igwe na-ebi akwụkwọ, igwe na-egbutu akpa, granulator na-emegharị ihe mkpofu na ahịrị mmepụta dị iche iche maka akpa rọba. Ngwaahịa na-ekpuchi akpa vest, akpa mkpofu, akpa aka, akpa uwe, akpa ngwaike, akpa ihe ịchọ mma, akpa nri, akpa isi kaadị, akpa akwụkwọ kraft / PLA composite bags, wdg. , ihe akaebe na-adịghị mma, nke na-adịghị egbu egbu, akara dị mma, mgbatị dị mma, ọdịdị dị mma, nchebe gburugburu ebe obibi.
Ok nkwakọ ngwaahịa na-agbaso echiche nke nchebe gburugburu ebe obibi ma na-agba mbọ na mmepe mmepe nke gburugburu ebe obibi, nke ọma mepụtara dị mma maka ụlọ ọrụ nkwakọ ngwaahịa na nri nri zuru oke na ngwaahịa na ngwaahịa, nwere ahụmahụ bara ụba na ụlọ ọrụ nkwakọ ngwaahịa ma na-anabata nhazi nke mkpofu, kwalite ojiji akụrụngwa, ma na-arụsi ọrụ ike na-arụsi ọrụ ike na-azụlite nri-ọkwa nri zuru ezu biodegradable ngwaahịa.
3. Kedu ngwaahịa nwere ike iji akpa biodegradable mee ihe?
A na-eji akpa rọba na-emebi emebi eme ihe n'ọtụtụ ebe n'uwe elu, ịkwa akwa, uwe, uwe, akwa, nri, ngwaike, ngwa elektrọnik, ịchọ mma na ụlọ ọrụ ndị ọzọ. Akpa rọba nke nwere ike ime ihe nwere ọtụtụ ihe eji emechi ihe, dị ka ọkpụkpụ nrapado, zipa, teepu, wdg, na akpa rọba nwere ike ime ka a na-ejikọta ya na akwụkwọ, nke nwere ike ịgbaji akụkụ ahụ dị n'okpuru. Ugbu a, akpa rọba na-emebi emebi na-abanye n'ụdị ndụ niile, ma enwere ụdị dị iche iche; N'ọdịnihu, akpa rọba ga-abụ ngwaahịa zuru oke nke ụlọ ọrụ nkwakọ ngwaahịa.
