Polyhydroxyalkanoate PHA
Polyhydroxyalkanoate yakapfupikiswa sePHA, izwi rinowanzoreva kirasi yeakakwira molecular uremu polyesters akagadzirwa nehutachiona. PHA inogadzirwa kubva muchibage, mbatatisi uye imwe starch-based biomass kana mashanga cellulose seyakabikwa, yakaviriswa kuti ibudise lactic acid, uye yakawedzera kucheneswa uye polymerized kugadzirira yakakwirira-kuchena PLA, inoshamwaridzana nenharaunda, isina chepfu, antibacterial, murazvo. retardant uye yakanaka biocompatibility.
PHA jekiseni rekuumba giredhi, blister giredhi, blow firimu giredhi, furo giredhi, uye zvimwe zvizere biodegradable zvinhu mumutsara wese. PHAs imhando yepolyhydroxyalkanoates (PHA) zvinhu, inova biopolymer zvinhu zvinogadzirwa zvakananga kuburikidza kuburikidza nekuvirisa kwehutachiona mutwupukanana. MaPHA ane yakakwirira yakawedzera kukosha zvivakwa senge biocompatibility, biodegradability, uye piezoelectric zvivakwa. Ivo vane yakanaka yekushandisa uye kugadzirisa zvivakwa, uye yavo yekutanga zvinhu zvakafanana ne polypropylene. Iwo anogona kugadzirwa uye kuumbwa uchishandisa echinyakare mapurasitiki ekugadzira midziyo senge jekiseni kuumba, extrusion, kuridza firimu, waya yekudhirowa, uye kuumba, uye inogona kutsiva ruzhinji rwepetroleum yakavakirwa mapurasitiki. Iyo biodegradation rate yePHAs inogona kudzorwa nekuumbwa kwemacopolymers avo zvichienderana neakasiyana mashandisirwo ezvinodiwa.

Chinhu chikuru chePHA ndechekuti inogona kuodzwa nema microorganisms munharaunda dzese, senge manyowa, ivhu, mvura yegungwa, zvichingodaro. Zvigadzirwa mushure mekuora kazhinji mvura uye kabhoni yakavakirwa, uye haizosvibisa nharaunda. Kuwanikwa uku kwakasimudza izwi rePHA mumunda wezvigadzirwa zvepurasitiki zvinoraswa pasi pechirambidzo chepurasitiki, uye zvakapawo girinhi uye yakadzikama budiriro yekufunga kune yekutanga mapurasitiki ekutsiva zvigadzirwa.
PHA chinhu chinoora chinoshandisa biomass inogona kudzokororwa seyakabikwa uye inogadzirwa zvachose nema microorganisms; PHA ine kuita kwakanakisa maererano neiyo biological isiri-chepfu uye ipurasitiki isina muchetura kana kunyange inodyiwa inoparara.
Kudzokorodza uye kurapwa kwePHA kunewo zvakanakira zvakasarudzika - mapurasitiki emarara echinyakare anowanzo kuraswa kuburikidza nemarara kana kupisa, zvichikonzera kusvibiswa kwezvinhu zvakaita senyika nemhepo. PHA, kune rumwe rutivi, inogona kugadziriswa kuburikidza nekutevedzana kwekurapa uye kushandiswa sechikafu kuburitsa mabhenefiti ehupfumi zvakare, kuwana huviri kutenderera kwezvinhu uye hupfumi.
