Utilisation du D-LACTIDE<\/strong><\/h2>\n

Le D-(+)-Propyl cross ester est un diester cyclique de l'acide lactique, un sous-produit produit par les sarcom\u00e8res musculaires et les globules rouges lorsque le corps d\u00e9compose les hydrates de carbone pour obtenir de l'\u00e9nergie \u00e0 de faibles niveaux d'oxyg\u00e8ne. Un catalyseur appropri\u00e9 peut \u00eatre utilis\u00e9 pour polym\u00e9riser l'ester propionylique en acide polylactique, ce qui permet d'obtenir un mat\u00e9riau aux propri\u00e9t\u00e9s utiles.<\/h4>\n

<\/h4>\n

D-LACTIDE Stockage<\/strong><\/h2>\n

1. Cette s\u00e9rie de produits est constitu\u00e9e de mat\u00e9riaux biod\u00e9gradables. \u00c9viter tout contact avec l'eau, les substances acides, les substances alcalines, les r\u00e9actifs alcooliques et autres r\u00e9actifs susceptibles de provoquer une d\u00e9gradation du produit pendant le stockage.<\/h4>\n

2. Cette s\u00e9rie de produits doit \u00eatre scell\u00e9e et stock\u00e9e dans un endroit sec et \u00e0 basse temp\u00e9rature (r\u00e9frig\u00e9rateur \u00e0 -20 degr\u00e9s) pendant le stockage, et doit \u00eatre scell\u00e9e \u00e0 l'aide d'une scelleuse (les produits restants apr\u00e8s utilisation ne doivent pas \u00eatre emball\u00e9s et stock\u00e9s dans des sacs \u00e0 fermeture \u00e9clair).<\/h4>\n

3. Lors de l'utilisation, sortez le produit du r\u00e9frig\u00e9rateur et placez-le \u00e0 temp\u00e9rature ambiante, et attendez que la temp\u00e9rature atteigne la temp\u00e9rature ambiante pour essuyer l'humidit\u00e9 condens\u00e9e \u00e0 la surface du sac d'emballage avant de l'ouvrir (l'humidit\u00e9 de l'air se condense \u00e0 la surface du produit et le d\u00e9grade lorsqu'il est sorti du r\u00e9frig\u00e9rateur sans temp\u00e9rature constante et qu'il est ouvert). L'humidit\u00e9 de l'air de l'environnement pendant l'utilisation doit \u00eatre inf\u00e9rieure \u00e0 35% afin d'\u00e9viter que les produits restants ne deviennent humides et n'affectent la qualit\u00e9 du produit.<\/h4>\n

Comment distinguer le D-LACTIDE et le L-LACTIDE ?<\/strong><\/h2>\n

1. Les cristaux en forme d'aiguille du L-lactide et du D-lactide sont identiques, le point de fusion est le m\u00eame et l'apparence est indiscernable. La forme rac\u00e9mique peut \u00eatre distingu\u00e9e par son aspect, elle n'a pas la forme d'une aiguille et son point de fusion est diff\u00e9rent.
\n2. Le magn\u00e9tisme nucl\u00e9aire et l'infrarouge ne peuvent \u00eatre distingu\u00e9s, la rotation optique peut \u00eatre distingu\u00e9e, la gaucherie est n\u00e9gative, la droiterie est positive, la rac\u00e9misation n'a pas de rotation optique.<\/h4>\n
