Polyhydroxyalkanoate PHA

Polyhydroxyalkanoate mu magambo ahinnye yiswe PHA, ni ijambo rusange ryicyiciro cyurwego rwimiterere ya molekile ndende ya polyester ikomatanyirijwe hamwe na mikorobe. PHA ikozwe mu bigori, ibirayi hamwe na biomass cyangwa ibinyamisogwe bishingiye kuri krahisi nk'ibikoresho fatizo, bigahinduka kugira ngo bitange aside ya lactique, hanyuma bigasukurwa kandi bigashyirwa mu bikorwa kugira ngo hategurwe PLA isukuye cyane, itangiza ibidukikije, idafite uburozi, antibacterial, flame retardant kandi biocompatibilité nziza.

Icyiciro cyo gutera inshinge za PHA, icyiciro cya blisteri, amanota ya firime, icyiciro cya furo, nibindi bikoresho byangiza umubiri wose. PHAs ni ubwoko bwa polyhydroxyalkanoates (PHA), ni ibikoresho bya biopolymer bihujwe neza binyuze muri fermentation ya mikorobe mikorobe. PHAs ifite agaciro kiyongereye cyane nka biocompatibilité, biodegradability, na piezoelectric. Bafite imikoreshereze myiza nogutunganya, nibintu byabo byibanze bisa na polypropilene. Birashobora gutunganywa no kubumba hakoreshejwe ibikoresho gakondo byo gutunganya plastike nko kubumba inshinge, gusohora, kuvuza firime, gushushanya insinga, no kubumba, kandi birashobora gusimbuza igice kinini cya plastiki ishingiye kuri peteroli. Igipimo cyibinyabuzima cya PHAs gishobora kugenzurwa nuburinganire bwa kopi zabo ukurikije ibikenewe bitandukanye.
