Abstract

L'invention concerne une installation de mesure de la viscosité en solution de polymères thermoplastiques, notamment de polyamides tels que le polyamide- 11 et le polyamide-12 suivant laquelle une quantité de polyamide pesée exactement est mise en dissolution dans un poids lui aussi mesuré exactement d'un solvant tel que le métacrésol. Cette installation est caractérisée en ce qu'elle comprend une première chaîne de réception, d'accumulation et de transport de récipients contenant le mélange de solvant et de poudre de polyamide, un poste de chauffage et d'agitation des récipients, un mécanisme de transfert des récipients à une deuxième chaîne d'accumulation et de transport des récipients, un poste de mise des récipients à la température requise pour la mesure, un poste de viscosimétrie et un mécanisme de transfert à une troisième chaîne d'accumulation et d'évacuation des récipients.
