Polyhydroxyalkanoate PHA

Polyhydroxyalkanoate wanda aka rage shi azaman PHA, kalma ce ta gaba ɗaya don nau'in polyesters masu nauyi masu nauyi waɗanda ƙananan ƙwayoyin cuta suka haɗa. An yi PHA daga masara, dankalin turawa da sauran sitaci na tushen biomass ko bambaro cellulose a matsayin kayan albarkatun kasa, fermented don samar da lactic acid, da kuma kara tsarkakewa da kuma polymerized don shirya high-tsarki PLA, wanda yake shi ne m muhalli, ba mai guba, antibacterial, harshen wuta. retardant da kyau biocompatibility.

PHA allura gyare-gyaren sa, blister sa, busa fim sa, kumfa sa, da sauran cikakken biodegradable kayan a ko'ina cikin dukan layi. PHAs wani nau'in abu ne na polyhydroxyalkanoates (PHA), wanda abu ne na bioopolymer wanda aka haɗa kai tsaye ta hanyar haɓakar ƙananan ƙwayoyin cuta a cikin ƙananan ƙwayoyin cuta. PHAs suna da ƙarin kaddarorin ƙima kamar haɓakar halittu, haɓakar halittu, da kaddarorin piezoelectric. Suna da kyakkyawan amfani da kaddarorin sarrafawa, kuma ainihin kaddarorin su suna kama da polypropylene. Ana iya sarrafa su da gyare-gyare ta hanyar amfani da kayan sarrafa filastik na gargajiya kamar gyaran allura, extrusion, busa fim, zanen waya, da gyare-gyare, kuma za su iya maye gurbin mafi yawancin robobin tushen man fetur. Ana iya sarrafa ƙimar ɓarnawar halittu na PHAs ta hanyar abun da ke tattare da copolymer ɗin su bisa ga buƙatun aikace-aikace daban-daban.
