  • distillation residues and in particular toluene diisocyanates are treated, but also production residues with toxic or high-boiling solvents from chemistry and pharmaceutical production, washing solutions and paint sludge, polymer solutions, elastomer solutions from the solvent, adhesives and sealants.

  • a mixing kneader also multifunctional processes can be combined, for example heating, drying, melting, crystallizing, mixing, degassing, reacting - all this continuously or in batches.
  • Polymers, elastomers, inorganic products, residues, pharmaceutical products, food products, printing inks are thus manufactured or treated.
  • vacuum sublimation / desublimation can also take place, whereby chemical precursors, e.g. Anthrachinon, metal chlorides, ferrocenes, iodine, organometallic compounds, etc. are purified.

  • mixing bars applied to disk elements interact with each other.
  • the mixing bars have the task of cleaning product-contacted areas of the mixer housing, the shafts and the disk elements as well as possible and thus avoid unmixed zones.
  • the randomness of the mixing bars leads to high local mechanical loads on the mixing bars and the shafts. These force peaks occur in particular when engaging the mixing bars in those zones where the product can escape badly. Such zones are e.g. Given where the disc elements are placed on the shaft.
  • This back-mixing in the feed zone has the considerable advantage that the product, which is relatively liquid, is mixed with an already polymerized product which is slightly higher viscosity.
  • the viscosity is increased at an early stage in the feed zone, so that heat is introduced into the product or the feed stream early on as a result of the shearing action by the corresponding kneading elements, so that the exotherm is also started quickly. This means that early degassing of solvent and / or unpolymerized monomers or co-monomers takes place.

Abstract

L'invention concerne un procédé d'exécution continue d'une polymérisation de monomères ou co-monomères, notamment une homopolymérisation et copolymérisation de diènes, comme de butadiènes, isoprènes, pipérylènes, en polymères dans un réacteur (1, 1.1, 1.2), notamment dans un mélangeur-malaxeur pourvu d'au moins une entrée (2) qui est destinée au produit à polymériser (charge) et qui se prolonge, dans le réacteur (1, 1.1, 1.2), par une zone d'alimentation (3) de la charge. Le but de l'invention est de prévoir dans la zone d'alimentation (3) la réalisation d'un rétromélange du produit greffé avec un flux de charge, la zone d'alimentation (3) où se produit le rétromélange, représentant maximum 50 % (> 0 à 0,5 du champ de positionnement des produits) de la longueur du réacteur affectée au procédé.
