Polyhydroxyalkanoate PHA
Polyhydroxyalkanoate yofupikitsidwa ngati PHA, ndi mawu wamba a gulu la ma polyesters olemera kwambiri a molekyulu opangidwa ndi tizilombo tating'onoting'ono. PHA amapangidwa kuchokera chimanga, mbatata ndi zina wowuma zochokera zotsalira zazomera kapena udzu mapadi monga zopangira, thovu kutulutsa lactic acid, ndi kuyeretsedwanso ndi polymerized kukonzekera mkulu-kuyera PLA, amene ndi wochezeka zachilengedwe, sanali poizoni, antibacterial, lawi. zotsalira komanso zabwino biocompatibility.
Gulu lopangira jakisoni wa PHA, grade blister, giredi lafilimu, thovu, ndi zinthu zina zomwe zimatha kuwonongeka pamzere wonsewo. PHA ndi mtundu wa zinthu za polyhydroxyalkanoates (PHA), zomwe ndi biopolymer yopangidwa mwachindunji kudzera mu kupesa kwa tizilombo tating'onoting'ono. Ma PHA ali ndi zinthu zamtengo wapatali monga biocompatibility, biodegradability, ndi piezoelectric properties. Amakhala ndi magwiritsidwe abwino komanso opangira zinthu, ndipo zinthu zawo zoyambira ndizofanana ndi polypropylene. Atha kukonzedwa ndikuwumbidwa pogwiritsa ntchito zida zamapulasitiki zamapulasitiki monga jekeseni, kutulutsa, kuwomba filimu, kujambula mawaya, ndi kuumba, ndipo zitha kulowa m'malo ambiri apulasitiki opangidwa ndi mafuta. Kuchuluka kwa biodegradation kwa ma PHA kumatha kuyendetsedwa ndi kapangidwe ka ma copolymer awo malinga ndi zosowa zosiyanasiyana zamagwiritsidwe.

Chinthu chachikulu cha PHA ndi chakuti chikhoza kuwonongeka ndi tizilombo toyambitsa matenda pafupifupi m'madera onse, monga kompositi, nthaka, madzi a m'nyanja, ndi zina zotero. Zogulitsa zikawola nthawi zambiri zimakhala zamadzi ndi kaboni, ndipo sizidzawononga chilengedwe. Kupeza uku kwakweza mawu a PHA pankhani yazinthu zotayidwa zapulasitiki pansi pa chiletso cha pulasitiki, komanso kwapereka malingaliro obiriwira komanso okhazikika azinthu zoyambira zosinthira pulasitiki.
PHA ndi zinthu zowonongeka zomwe zimagwiritsa ntchito biomass zongowonjezwdwa ngati zopangira ndipo zimapangidwa kwathunthu ndi tizilombo tating'onoting'ono; PHA ili ndi magwiridwe antchito abwino kwambiri pazachilengedwe zopanda poizoni ndipo ndi pulasitiki yopanda poizoni kapena yodyedwa.
Kubwezeretsanso ndi kuchiza kwa PHA kulinso ndi maubwino apadera - mapulasitiki a zinyalala zachikhalidwe nthawi zambiri amatayidwa kudzera m'nthaka kapena kutenthedwa, zomwe zimapangitsa kuti pakhale vuto la kuipitsa malo monga nthaka ndi mpweya. PHA, kumbali ina, ikhoza kukonzedwa kudzera muzochizira zingapo ndikugwiritsidwa ntchito ngati chakudya kuti ibweretse phindu pazachuma kachiwiri, kukwaniritsa kuzungulira kwapawiri kwazinthu ndi chuma.
