Ikpughe starch ọka na Bioplastics: Gịnị bụ ọrụ ya?

Na ndụ anyị kwa ụbọchị, ngwaahịa plastik dị ebe niile.Otú ọ dị, nsogbu gburugburu ebe obibi na-arịwanye elu nke plastik omenala mere ka ndị mmadụ na-achọ ihe ndị ọzọ na-adigide.Nke a bụ ebe bioplastics na-abata.N'ime ha, starch ọka na-arụ ọrụ dị mkpa dị ka ihe na-emekarị na bioplastics.Yabụ, kedu ihe bụ ọrụ nke yaọka ọka na bioplastics?

 

1.Gịnị bụ Bioplastics?
Bioplastics bụ plastik emere site na akụrụngwa enwere ike imeghari dịka osisi ma ọ bụ microorganisms.N'adịghị ka plastik ọdịnala, a na-eme bioplastics site na akụrụngwa enwere ike imeghari, si otú a na-akpata obere mmetụta gburugburu ebe obibi.A na-ejikarị starch ọka, n'ime ha, dịka otu n'ime ihe ndị dị na bioplastics.

2.The Role of Corn Starch na Bioplastics


Starch ọka na-arụ ọrụ atọ dị mkpa:
Cornstarch na-ekere òkè n'ịkwalite, ịkwado na imeziwanye ihe nhazi na bioplastics.Ọ bụ polymer nke enwere ike ijikọ ya na polymers ndị ọzọ nwere ike imebi ma ọ bụ plasticizers iji mepụta ụlọ kwụsiri ike.Site n'ịgbakwụnye ihe mgbakwunye kwesịrị ekwesị na starch ọka, enwere ike gbanwee ike, mgbanwe na mmebi nke bioplastics, na-eme ka ha dị mma maka ọnọdụ ngwa dị iche iche.
Ịkwalite Ike Mechanical: Ntinye nke starch ọka nwere ike ime ka ike siri ike na ike nke bioplastics dịkwuo mma, na-eme ka ha dịkwuo ogologo.

Imelite arụmọrụ nhazi: Ọnụnọ nke starch ọka na-eme ka bioplastics dịkwuo mma n'oge nhazi, na-eme ka mmepụta nke ngwaahịa dị iche iche dị iche iche.

Ọzọkwa, starch ọka nwere ezigbo biodegradaability.N'okpuru ọnọdụ gburugburu ebe obibi kwesịrị ekwesị, microorganisms nwere ike ịkụda starch ọka n'ime ogige organic dị mfe, na-emecha nweta mmebi zuru oke.Nke a na-enye ohere ịmegharị bioplastics ka ejiri ya mee ihe, na-ebelata mmetọ gburugburu ebe obibi.

Otú ọ dị, starch ọka na-ewetakwa ụfọdụ ihe ịma aka.Dịka ọmụmaatụ, na gburugburu okpomọkụ ma ọ bụ oke iru mmiri, bioplastics na-enwekarị ike ịkwụsị nkwụsi ike, na-emetụta ndụ ha na arụmọrụ ha.Iji dozie okwu a, ndị ọkà mmụta sayensị na-arụ ọrụ n'ịchọta ihe mgbakwunye ọhụrụ ma ọ bụ imeziwanye usoro mmepụta ihe iji kwalite nkwụsị ọkụ na mmiri mmiri nke bioplastics.

3. Ngwa nke ọka starch na Specific Bioplastics


Ngwa nke starch ọka n'ime ihe ndị dị ndụ dị iche iche dịgasị iche dabere na ihe ndị a chọrọ na ebumnuche iji ngwaahịa ikpeazụ.Nke a bụ ọmụmaatụ ole na ole:

Polylactic Acid (PLA): PLA bụ bioplastic nke a na-enwetakarị site na starch ọka.Starch ọka na-eje ozi dị ka nri nri maka mmepụta nke lactic acid, nke a na-emezi polymerized ka ọ bụrụ PLA.PLA ejiri starch ọka mesie ike na-egosipụta ihe arụrụ arụ arụrụ arụ, dị ka ike tensile na nguzogide mmetụta.Ọzọkwa, mgbakwunye nke ọka starch nwere ike ịkwalite biodegradability nke PLA, na-eme ka ọ dị mma maka ngwa ebe nchegbu gburugburu ebe obibi dị mkpa, dị ka.mkpofu ihe cutlery, nkwakọ nri, na ihe nkiri mulch nke ugbo.

Polyhydroxyalkanoates (PHA): PHA bụ ụdị ọzọ nke bioplastic nke enwere ike imepụta site na iji starch ọka dị ka isi iyi carbon.Microorganisms na-agbakọ starch ọka iji mepụta polyhydroxybutyrate (PHB), nke bụ ụdị PHA.PHA ndị ejiri starch ọka mesie ike na-enwekarị nkwụsi ike ọkụ yana ihe arụrụ arụ.Bioplastics ndị a na-achọta ngwa n'akụkụ dị iche iche, gụnyere nkwakọ ngwaahịa, ngwaọrụ ahụike na ọrụ ugbo.

Bioplastics Dabere Starch: N'ọnọdụ ụfọdụ, a na-ahazi starch ọka ozugbo ka ọ bụrụ bioplastics na-enweghị mkpa maka usoro polymerization ọzọ.Bioplastics dabeere na starch na-enwekarị ngwakọta nke starch ọka, plasticizers, na ihe mgbakwunye iji melite nhazi na njirimara njedebe.A na-eji bioplastics ndị a na ngwa ndị dị ka akpa atụfu, arịa nri, na tebụl a na-atụfu ya.

Ịgwakọta na Polymers ndị ọzọ na-emebi emebi: A pụkwara ịgwakọta starch ọka na polymers ndị ọzọ nwere ike imebi, dị ka polyhydroxyalkanoates (PHA), polycaprolactone (PCL), ma ọ bụ polybutylene adipate-co-terephthalate (PBAT), iji mepụta bioplastics nwere ihe eji eme ya.Ngwakọta ndị a na-enye nguzozi nke ike igwe, mgbanwe na biodegradability, na-eme ka ha dabara maka ngwa dị iche iche sitere na nkwakọ ngwaahịa ruo ọrụ ugbo.

Ọrụ nke starch ọka na bioplastics na-agafe karịa ịkwalite arụmọrụ;ọ na-enyekwara aka belata ịdabere na plastik ọdịnala sitere na mmanụ ala, na-ebute mmepe nke ihe eji eme gburugburu ebe obibi.Site n'ọganihu na teknụzụ, anyị na-atụ anya ịhụ ngwaahịa bioplastic ọhụrụ ndị ọzọ dabere na akụrụngwa enwere ike imeghari dị ka starch ọka.

Na nchịkọta, starch ọka na-ekere òkè dị iche iche na bioplastics, ọ bụghị nanị na-akwalite nkwụsi ike nhazi nke plastik kamakwa na-akwalite ịdị ndụ ha, si otú ahụ na-ebelata mmetụta gburugburu ebe obibi.Site na ọganihu nkà na ụzụ na-aga n'ihu na mmepụta ihe ọhụrụ, bioplastics dị njikere ịrụ ọrụ ka ukwuu n'iweta uru ndị ọzọ na gburugburu ụwa anyị.
