Iithegi zeMveliso

Yintoni iPolyhydroxybutyrate PHB eneCAS 26744-04-7?

I-PHB iveliswa ngama-microorganisms, ngokucacileyo ekuphenduleni iimeko zoxinzelelo lwe-physiological. Ubukhulu becala yimeko yezondlo ezilinganiselweyo. I-polymer ngokuyinhloko imveliso ye-carbon assimilation (ukusuka kwi-glucose okanye isitashi) kwaye isetyenziswe yi-microorganisms njengendlela yokugcinwa kwamandla e-molecule ye-metabolism xa enye imithombo yamandla eqhelekileyo ingekho.

Isicelo

I-PHB inethemba elibanzi lokusetyenziswa kwezixhobo zonyango, iiplastiki ezonakeleyo, itafile elahlayo, iifreyimu zemiboniso, ukupakishwa, ukucocwa kwelindle, iithoyi kunye nezinye iindawo.
EzoLimo: umthwali we-biodegradable wefilimu zezolimo, izitshabalalisi ezisebenza ixesha elide kunye nezichumisi
Iyeza: I-sutures yotyando, iinzipho zengqiniba, ukutshintshwa kwethambo, ukutshintshwa komthambo wegazi Umzi-mveliso: izinto zokupakisha, iimveliso zococeko, idiapers, izinto ezisebenzayo zamehlo.
Kwintsimi yezixhobo zonyango, i-polyhydroxybutyrate ingasetyenziselwa ukulungiselela izixhobo zokuthutha iziyobisi ezizinzileyo, izixhobo zobunjineli bezicubu, njl. Kwintsimi yokupakisha, iimveliso zokuthotywa kwe-polyhydroxybutyrate ikakhulu ziyi-carbon dioxide kunye namanzi, ehambelana nohlaza lwangoku. kunye nengqiqo yophuhliso lokusingqongileyo.
