Polyhydroxyalkanoate PHA
I-Polyhydroxyalkanoate efinyeziweyo njenge-PHA, ligama eliqhelekileyo lodidi lwe-polyester ezinobunzima bemolekyuli ezidityaniswe zii-microorganisms. I-PHA yenziwe ngombona, iitapile kunye nezinye i-biomass esekelwe kwisitatshi okanye i-straw cellulose njengezinto eziluhlaza, ezivundisiweyo ukuvelisa i-lactic acid, kwaye ihlanjululwe ngakumbi kwaye ifakwe i-polymerized ukulungiselela i-PLA ephezulu, ehambelana nokusingqongileyo, ayinayo ityhefu, i-antibacterial, idangatye. i-retardant kunye ne-biocompatibility elungileyo.
Ibakala lokubumba inaliti ye-PHA, ibakala leblister, ibakala lefilimu yokuvuthela, ibakala logwebu, kunye nezinye izinto ezinokubola ngokupheleleyo kuwo wonke umgca. I-PHAs luhlobo lwe-polyhydroxyalkanoates (PHA) imathiriyeli, eyimathiriyeli ye-biopolymer edityaniswe ngokuthe ngqo nge-microbial fermentation kwii-microorganisms. I-PHAs ineempawu zexabiso eliphezulu elongezelelweyo ezifana ne-biocompatibility, biodegradability, kunye ne-piezoelectric properties. Banokusetyenziswa kakuhle kunye neempawu zokucubungula, kwaye iimpawu zabo ezisisiseko zifana ne-polypropylene. Zinokucutshungulwa kwaye zibunjwe kusetyenziswa izixhobo zokwenziwa kweplastiki zemveli ezifana nokubumba inaliti, i-extrusion, ukuvuthela ifilimu, umzobo wecingo, kunye nokubumba, kwaye zinokuthatha indawo yobuninzi beeplastiki zepetroleum. Izinga le-biodegradation ye-PHAs inokulawulwa ngokubunjwa kwee-copolymers zabo ngokweemfuno ezahlukeneyo zesicelo.

Isici esikhulu kunazo zonke se-PHA kukuba sinokuchithwa ngama-microorganisms phantse kuzo zonke iindawo, ezifana nomquba, umhlaba, amanzi olwandle, njalo njalo. Iimveliso emva kokubola ubukhulu becala ngamanzi kunye nekhabhoni esekwe, kwaye aziyi kungcolisa indalo. Oku kufunyaniswe kuye kwaphakamisa ilizwi le-PHA kwintsimi yeemveliso zeplastiki ezilahlayo phantsi kwemvelaphi yokuvinjelwa kweplastiki, kwaye kwanikezela ukucinga okuluhlaza kunye nophuhliso oluzinzileyo kwiimveliso eziphambili zeplastiki.
I-PHA yinto enokuchithwa kwe-biodegradable esebenzisa i-biomass enokuhlaziywa njengento eluhlaza kwaye ihlanganiswe ngokupheleleyo yi-microorganisms; I-PHA inentsebenzo egqwesileyo ngokumalunga ne-biological non-toxicity kwaye iyiplastiki engeyotyhefu okanye enokutyiwa enokubola.
Ukurisayikilishwa kunye nokunyangwa kwe-PHA nako kuneenzuzo ezizodwa - iiplastiki zenkunkuma eziqhelekileyo zilahlwa ngokulahla okanye ukutshiswa, okukhokelela kwimiba yongcoliseko efana nomhlaba kunye nomoya. I-PHA, kwelinye icala, inokucutshungulwa ngoluhlu lwezonyango kwaye isetyenziswe njengesondlo ukuvelisa inzuzo yezoqoqosho kwakhona, ukufezekisa umjikelo ombini wezinto eziphathekayo kunye noqoqosho.
