I-L-Lactide CAS 4511-42-6

Incazelo emfushane:

I-L-lactide, eyaziwa nangokuthi i-L-lactide cyclic diester, iyikristale eqinile etholakala ezinsizeni ezivuselelekayo.Iyisandulela se-polylactic acid (PLA), i-polymer ebolayo esetshenziswa kabanzi ekukhiqizeni amapulasitiki, imicu kanye nezinto zokupakisha.I-L-lactide inezici zesisindo samangqamuzana aphezulu, izakhiwo ezinhle kakhulu zemishini, kanye nokuvumelana okuhle kwe-biocompatibility.

Izinzuzo

Ubumsulwa: I-L-Lactide yethu (i-CAS 4511-42-6) ihlanganiswa ngenqubo yokuhlanza eqinile ukuze kuqinisekiswe ukuhlanzeka okuphezulu.Umkhiqizo unokuhlanzeka okuncane okungama-99%, okuqinisekisa ukusebenza kahle nokuthembeka kwawo ezinhlotsheni zezicelo.

Ukubukeka: I-L-lactide iyikristalu eqinile emhlophe, engenaphunga, encibilika kalula kuzincibilikisi ezivamile zemvelo.Ubukhulu bayo bezinhlayiya ezinhle kulula ukuphatha futhi bufanele izinqubo ezihlukahlukene zokukhiqiza.

Isitoreji: Ukuze ugcine izinga elihle le-L-lactide, kufanele igcinwe endaweni epholile, eyomile ekude nelanga eliqondile.Izimo ezifanele zokugcina zizovimbela ukuwohloka futhi ziqinisekise impilo ewusizo yomkhiqizo.

Isicelo: I-L-lactide isetshenziswa kakhulu ekukhiqizeni ama-polymers abolayo njenge-PLA.Lawa ma-polymers athola ukunakwa okukhulu embonini yokupakisha ngenxa yezakhiwo zawo ezinobungani bemvelo namandla okunciphisa imfucuza yepulasitiki.Ngaphezu kwalokho, ngenxa ye-biocompatibility yayo kanye ne-bioabsorbability, i-L-lactide ingasetshenziswa futhi ekwenzeni izinto zezokwelapha, izinhlelo zokulethwa kwezidakamizwa, nezikafula zobunjiniyela bezicubu.

Ekuphetheni:

Njengomphakeli owethembekile, siyaziqhenya ngokuhlinzeka nge-L-Lactide (CAS 4511-42-6) ehlangabezana namazinga aphezulu kakhulu embonini.Sizibophezele ekuletheni imikhiqizo eyingqayizivele, esekelwa ithimba lochwepheshe abazinikele ekunikezeni isevisi yamakhasimende eyingqayizivele.Sikholelwa ukuthi ukusebenzisana kwe-L-lactide ngezindlela ezihlukahlukene, ukwethembeka kanye nezici zemvelo kuyenza ilungele ukusetshenziswa okuhlukahlukene.Uma uneminye imibuzo noma udinga amasampula, sicela ukhululeke ukuxhumana nathi.
