Polyhydroxyalkanoate PHA

Polyhydroxyalkanoate abbreviated li PHA, yog ib lo lus dav dav rau cov chav kawm siab molecular hnyav polyesters synthesized los ntawm cov kab mob. PHA yog tsim los ntawm pob kws, qos yaj ywm thiab lwm yam hmoov txhuv nplej siab los yog straw cellulose ua raw cov ntaub ntawv, fermented los tsim lactic acid, thiab ntxiv purified thiab polymerized los npaj high-purity PLA, uas yog ib puag ncig tus phooj ywg, non-toxic, antibacterial, nplaim taws. retardant thiab zoo biocompatibility.

PHA txhaj tshuaj molding qib, qib blister, tshuab qib zaj duab xis, qib ua npuas ncauj, thiab lwm yam khoom siv biodegradable thoob plaws tag nrho cov kab. PHAs yog ib hom khoom siv polyhydroxyalkanoates (PHA), uas yog cov khoom siv biopolymer ncaj qha los ntawm cov kab mob microbial fermentation hauv cov kab mob. PHAs muaj cov khoom muaj nqis ntxiv xws li biocompatibility, biodegradability, thiab piezoelectric zog. Lawv muaj kev siv tau zoo thiab ua haujlwm zoo, thiab lawv cov khoom tseem ceeb zoo ib yam li polypropylene. Lawv tuaj yeem ua tiav thiab molded siv cov khoom siv yas xws li kev txhaj tshuaj molding, extrusion, zaj duab xis tshuab, hlau kos duab, thiab molding, thiab tuaj yeem hloov cov roj av feem ntau ntawm cov yas. Cov biodegradation tus nqi ntawm PHAs tuaj yeem tswj tau los ntawm cov khoom sib xyaw ntawm lawv cov copolymer raws li kev thov sib txawv.
