Polyhydroxybutyrate PHB CAS 26744-04-7
PHB yog tsim los ntawm cov kab mob microorganisms, thaj teb rau kev ntxhov siab ntawm lub cev. Nws yog feem ntau yog ib qho mob ntawm cov khoom noj tsawg. Cov polymer feem ntau yog cov khoom ntawm cov pa roj carbon assimilation (los ntawm cov piam thaj los yog cov hmoov txhuv nplej siab) thiab siv los ntawm cov kab mob ua ib daim ntawv ntawm lub zog cia molecule rau cov metabolism thaum lwm yam tsis muaj zog.

PHB muaj cov ntawv thov dav dav hauv cov ntaub ntawv kho mob, cov yas degradable, cov ntaub ntawv pov tseg, cov duab thaij duab, ntim khoom, dej phwj tuaj, cov khoom ua si thiab lwm yam.
Kev ua liaj ua teb: biodegradable carrier rau cov yeeb yaj kiab ua liaj ua teb, cov tshuaj tua kab ntev thiab cov chiv
Tshuaj: phais sutures, lub luj tshib rau tes, pob txha hloov, cov hlab ntsha hloov kev lag luam: ntim cov ntaub ntawv, cov khoom siv tu cev, cov pawm, cov khoom siv kho qhov muag
Hauv kev siv cov ntaub ntawv kho mob, polyhydroxybutyrate tuaj yeem siv los npaj cov tshuaj tiv thaiv-tso tawm cov ntaub ntawv, cov ntaub so ntswg engineering, thiab lwm yam. Hauv kev ntim khoom, polyhydroxybutyrate degradation cov khoom feem ntau yog carbon dioxide thiab dej, uas yog nyob rau hauv txoj kab nrog tam sim no ntsuab. thiab ib puag ncig tiv thaiv kev txhim kho lub tswv yim.
25kg / hnab los yog raws li cov neeg siv khoom xav tau
