Yintoni iPolyhydroxybutyrate PHB eneCAS 26744-04-7?

I-PHB iveliswa ziintsholongwane, ngokubonakalayo xa isabela kwiimeko zoxinzelelo lwe-physiological. Ngokuyintloko yimeko yezakhamzimba ezinqongopheleyo. I-polymer ngokuyintloko yimveliso yokufunxwa kwekhabhoni (kwi-glucose okanye kwisitatshi) kwaye isetyenziswa ziintsholongwane njengohlobo lwemolekyuli yokugcina amandla kwi-metabolism xa eminye imithombo yamandla eqhelekileyo ingafumaneki.

Isicelo

I-PHB inamathuba amaninzi okusetyenziswa kwizixhobo zonyango, iiplastiki ezibolayo, izitya zetafile ezilahlwayo, iifreyimu zemiboniso, ukupakishwa, unyango lwamanzi amdaka, izinto zokudlala kunye nezinye iindawo.
Ezolimo: isithwali esibolayo seefilimu zezolimo, izibulali-zinambuzane ezisebenza ixesha elide kunye nezichumisi
Amayeza: Iimpahla zotyando, iinzipho zengqiniba, ukutshintshwa kwamathambo, ukutshintshwa kwemithambo yegazi. Ushishino: izinto zokupakisha, iimveliso zococeko, ii-diapers, izinto ezisebenzayo ezibonakalayo
Kwicandelo lezixhobo zonyango, i-polyhydroxybutyrate ingasetyenziselwa ukulungiselela izixhobo zokuthwala amayeza ezikhutshwa rhoqo, izixhobo zobunjineli bezicubu, njl. Kwicandelo lokupakisha, iimveliso zokubola kwe-polyhydroxybutyrate ikakhulu yi-carbon dioxide namanzi, okuhambelana nengcamango yangoku yophuhliso lokusingqongileyo nolwendalo.
