1.Propri\u00e9t\u00e9 du produit<\/h3>\n

L'acide acrylique est un liquide incolore, corrosif et d'odeur \u00e2cre. Compl\u00e8tement miscible \u00e0 l'eau et aux solvants organiques courants, il fond \u00e0 13 \u00b0C et bout \u00e0 140,9 \u00b0C sous pression atmosph\u00e9rique. Sa densit\u00e9 est de 1,051 g cm-\u00b3 \u00e0 20 \u00b0C ; sa pression de vapeur est de 1,33 kPa \u00e0 39,9 \u00b0C. La pression critique atteint 5,66 MPa.<\/p>\n

3.Champ d'application et utilisation<\/h3>\n

 <\/p>\n

L'acide acrylique est le monom\u00e8re de base des polym\u00e8res super-absorbants utilis\u00e9s dans les produits d'hygi\u00e8ne et les gels retenant l'eau. Il est copolym\u00e9ris\u00e9 pour produire des r\u00e9sines acryliques de haute performance, des adh\u00e9sifs sensibles \u00e0 la pression, des peintures, des finitions textiles et des rev\u00eatements pour le cuir. Ses esters servent d'\u00e9l\u00e9ments de base pour les plastiques sp\u00e9cialis\u00e9s, les d\u00e9tergents et les inhibiteurs de calcaire dans le traitement de l'eau.<\/p>\n

4. l'emballage et le stockage<\/h3>\n

 <\/p>\n

Livr\u00e9 en f\u00fbts d'acier rev\u00eatus d'\u00e9poxy de 200 kg, en conteneurs IBC de 1000 kg ou en conteneurs-citernes ISO de 20-24 m\u00b3. Les petites quantit\u00e9s de laboratoire sont emball\u00e9es dans des f\u00fbts HDPE de 25 kg avec des bondes ventil\u00e9es. Stocker dans un endroit frais et ombrag\u00e9, \u00e0 une temp\u00e9rature inf\u00e9rieure \u00e0 25 \u00b0C, \u00e0 l'abri des oxydants, des bases et des peroxydes ; maintenir 180-220 ppm d'inhibiteur MEHQ. Assurer une couverture d'azote et une mise \u00e0 la terre pendant le transfert pour \u00e9viter la polym\u00e9risation et les d\u00e9charges statiques.<\/p>","protected":false},"excerpt":{"rendered":"
