Polyhydroxyalkanoate PHA
Polyhydroxyalkanoate oo loo soo gaabiyo PHA, waa erey guud oo loogu talagalay fasalka polyester-ka culeyska sare ee unugyadu ay ka kooban yihiin nooleyaal. PHA waxay ka samaysan tahay galley, baradho iyo biomass kale oo istaarij ku salaysan ama cellulose caws sida alaab ceeriin ah, khamiiriyey si ay u soo saaraan lactic acid, oo dheeraad ah la sifeeyey iyo polymerized si loogu diyaariyo-nadiifinta sare PLA, taas oo ah deegaanka saaxiibtinimo, aan sun, bakteeriyada, olol. retardant iyo bioocompatibility wanaagsan.
Heerka duritaanka duritaanka ee PHA, darajada biliijka, fasalka afuufista, darajada xumbo, iyo walxaha kale ee si buuxda u baabi'in karo inta lagu jiro khadka oo dhan. PHAs waa nooc ka mid ah maaddada polyhydroxyalkanoates (PHA), kaas oo ah walxo biopolymer ah oo si toos ah loogu soo koobay halsano microbial ee noolaha. PHA-yadu waxay leeyihiin sifooyin qiimo sare leh oo lagu daray sida biocompatibility, biodegradability, iyo sifooyinka piezoelectric. Waxay leeyihiin adeegsi wanaagsan iyo siyaalo farsamaysan, waxayna hantidooda aasaasiga ahi la mid tahay polypropylene. Waxa lagu farsamayn karaa oo lagu qaabayn karaa iyadoo la isticmaalayo qalab dhaqameed oo balaastig ah sida samaynta duritaanka, extrusion, afuufista filimada, sawirida siliga, iyo qaabaynta, waxayna bedeli karaan badi caagadaha batroolka ku salaysan. Heerarka xaalufka noole ee PHA-yada waxaa lagu xakameyn karaa isku-dhafka kopolyemerayaashooda iyadoo loo eegayo baahida codsi ee kala duwan.

Sifada ugu weyn ee PHA waa in ay qurxin karaan nooleyaal ku dhawaad dhammaan deegaanka, sida compost, ciidda, biyaha badda, iyo wixii la mid ah. Alaabooyinka ka dambeeya burburka waxay u badan yihiin biyo iyo kaarboon ku salaysan, mana wasakhayn doonaan deegaanka. Daahfurkaani wuxuu kor u qaaday codka PHA ee goobta alaabta caaga ah ee la tuuri karo ee hoos yimaada asalka mamnuucida caagga ah, iyo sidoo kale waxay siisay fikrad horumarineed oo cagaaran iyo mid waara oo loogu talagalay alaabta beddelka caaga ah ee aasaasiga ah.
PHA waa shay noole deg degi karo oo u isticmaala bayoomass la cusboonaysiin karo sida walxo ceeriin ah waxaana lagu farsameeyay gebi ahaanba nooleyaal; PHA waxay leedahay waxqabad aad u wanaagsan marka loo eego sunta noolaha oo aan sun ahayn ama xataa balaastiig la cuni karo.
Dib-u-warshadaynta iyo daawaynta PHA waxay sidoo kale leedahay faa'iidooyin gaar ah - caagadaha qashinka dhaqameed guud ahaan waxaa lagu daadiyaa qashinka ama gubida, taasoo keenta arrimo wasakh ah sida dhulka iyo hawada. PHA, dhanka kale, waxaa lagu farsamayn karaa iyada oo loo marayo daawayn taxane ah waxaana loo isticmaali karaa quudin si loo dhaliyo faa'iidooyin dhaqaale mar kale, iyada oo la gaadhayo wareegyo laba geesood ah oo agab iyo dhaqaale ah.
