M\u00e9langeur ouvert \u00e0 deux rouleaux Lab<\/h1>\n\n\n\n

A m\u00e9langeur ouvert \u00e0 deux rouleaux de laboratoire<\/a><\/strong> comporte deux rouleaux dispos\u00e9s horizontalement qui tournent dans des directions oppos\u00e9es \u00e0 des vitesses diff\u00e9rentes. Lorsque le mat\u00e9riau est introduit dans la zone sup\u00e9rieure entre les deux rouleaux, il est aspir\u00e9 entre eux en raison du frottement et de l'adh\u00e9rence entre le mat\u00e9riau et les surfaces des rouleaux, ainsi que de la liaison entre les composants du mat\u00e9riau. <\/p>\n\n\n\n

Le mat\u00e9riau est ensuite soumis \u00e0 un cisaillement et \u00e0 une compression intenses, formant des feuilles qui s'enroulent autour de l'un des rouleaux. Lorsque le rouleau tourne, le mat\u00e9riau revient dans la zone situ\u00e9e entre les deux rouleaux. <\/p>\n\n\n\n

Par des cisaillements et des compressions r\u00e9p\u00e9t\u00e9s, le mat\u00e9riau s'assouplit et se plastifie, ce qui permet d'obtenir un m\u00e9lange uniforme des composants. Avant de m\u00e9langer les mati\u00e8res plastiques, les rouleaux doivent \u00eatre pr\u00e9chauff\u00e9s \u00e0 une temp\u00e9rature sp\u00e9cifique. <\/p>\n\n\n\n

Dans la plupart des cas, le traitement des mat\u00e9riaux en caoutchouc ne n\u00e9cessite pas de chauffage ; l'eau de refroidissement est utilis\u00e9e pour refroidir le mat\u00e9riau pendant le traitement, si n\u00e9cessaire.<\/p>","protected":false},"excerpt":{"rendered":"
