Polyhydroxybutyrate PHB nrog CAS 26744-04-7
PHB yog tsim los ntawm cov kab mob me me, zoo li teb rau cov xwm txheej kev ntxhov siab ntawm lub cev. Nws yog qhov xwm txheej ntawm cov as-ham tsawg. Cov polymer feem ntau yog cov khoom ntawm cov pa roj carbon assimilation (los ntawm glucose lossis starch) thiab yog siv los ntawm cov kab mob me me ua ib daim ntawv ntawm lub zog khaws cia rau kev ua haujlwm thaum lwm cov chaw muaj zog tsis muaj.

PHB muaj kev siv dav hauv cov ntaub ntawv kho mob, cov yas uas lwj tau, cov khoom siv rooj tog pov tseg, cov thav duab tsom iav, cov ntim khoom, kev kho dej phwj tuaj, cov khoom ua si thiab lwm yam.
Kev Ua Liaj Ua Teb: cov khoom siv biodegradable rau cov yeeb yaj kiab ua liaj ua teb, cov tshuaj tua kab thiab cov chiv uas ua haujlwm ntev
Tshuaj: Cov xov phais, cov rau tes ntawm lub luj tshib, hloov pob txha, hloov cov hlab ntsha Kev lag luam: cov ntaub ntawv ntim khoom, cov khoom siv tu cev, cov ntaub so ntswg, cov khoom siv kho qhov muag
Hauv kev kho mob, polyhydroxybutyrate tuaj yeem siv los npaj cov tshuaj uas tso tawm cov ntaub ntawv nqa khoom, cov ntaub ntawv tsim cov ntaub so ntswg, thiab lwm yam. Hauv kev ntim khoom, cov khoom lag luam polyhydroxybutyrate degradation feem ntau yog carbon dioxide thiab dej, uas yog raws li lub tswv yim kev tiv thaiv ib puag ncig thiab ntsuab tam sim no.
