Polyhydroxyalkanoate PHA
Polyhydroxyalkanoate oo loo soo gaabiyo PHA, waa erey guud oo loogu talagalay fasalka polyester-yada miisaanka sare leh ee molecular-ka oo ay sameeyeen noolaha yaryar. PHA waxaa laga sameeyaa galleyda, baradhada iyo biomass-ka kale ee ku salaysan istaarijka ama cellulose cawska sida walxo cayriin ah, oo la khamiiriyey si loo soo saaro lactic acid, ka dibna si dheeraad ah loo nadiifiyey oo loo polymerized si loo diyaariyo PLA saafi ah oo heer sare ah, kaas oo deegaanka u fiican, aan sun ahayn, bakteeriyada dila, dab-celiya iyo iswaafajin wanaagsan oo noolaha ah.
Heerka wax lagu duray ee PHA, heerka finan-ka, heerka filimka afuufa, heerka xumbada, iyo walxo kale oo si buuxda u baaba'aya oo dhan khadka oo dhan. PHA-yadu waa nooc ka mid ah walxaha polyhydroxyalkanoates (PHA), kaas oo ah walax biopolymer ah oo si toos ah loogu sameeyay halsano microbial ah oo ku jira noolaha yaryar. PHA-yadu waxay leeyihiin sifooyin qiimo sare leh sida iswaafajinta bio, baaba'aynta biogradability, iyo sifooyinka piezoelectric. Waxay leeyihiin sifooyin wanaagsan oo loo isticmaali karo iyo habayn, sifooyinkooda aasaasiga ahna waxay la mid yihiin polypropylene. Waxaa lagu farsameyn karaa oo lagu qaabayn karaa iyadoo la adeegsanayo qalabka wax lagu sameeyo balaastikada dhaqameed sida qaabaynta duritaanka, fidinta, afuufidda filimka, sawiridda siligga, iyo qaabaynta, waxayna beddeli kartaa inta badan balaastikada ku salaysan batroolka. Heerka baaba'aynta biogradatory ee PHA-yada waxaa lagu xakameyn karaa halabuurka copolymers-kooda iyadoo loo eegayo baahiyaha kala duwan ee codsiga.

Sifada ugu weyn ee PHA waa in ay burburin karto noolaha yaryar ee ku nool ku dhawaad dhammaan deegaannada, sida bacriminta, ciidda, biyaha badda, iwm. Badeecadaha ka dib marka la burburiyo waxay inta badan ku salaysan yihiin biyo iyo kaarboon, mana wasakheyn doonaan deegaanka. Daahfurkani wuxuu kor u qaaday codka PHA ee ku saabsan alaabada balaastikada ah ee la tuuri karo iyadoo la raacayo asalka mamnuucidda balaastikada, wuxuuna sidoo kale bixiyay fikir horumarineed oo cagaaran oo waara oo loogu talagalay alaabada beddelka balaastikada aasaasiga ah.
PHA waa walax baaba'aysa oo u adeegsata bayomaas la cusboonaysiin karo sida walxo cayriin ah waxaana si buuxda u sameeya noolaha yaryar; PHA waxay leedahay waxqabad aad u fiican marka la eego sun la'aanta bayoolojiga waana balaastig aan sun ahayn ama xitaa la cuni karo oo baaba'aya.
Dib-u-warshadaynta iyo daaweynta PHA waxay sidoo kale leedahay faa'iidooyin gaar ah - balaastikada qashinka dhaqameed waxaa guud ahaan lagu tuuraa qashin-qubka ama gubista, taasoo keenta arrimo wasakheyn ah sida dhulka iyo hawada. Dhanka kale, PHA waxaa lagu farsameyn karaa taxane daaweyn ah waxaana loo isticmaali karaa quudin si loo soo saaro faa'iidooyin dhaqaale mar kale, iyadoo la gaarayo wareeg laba-geesood ah oo agab iyo dhaqaale ah.
