Abstract
Divulgation d'une méthode et d'un appareil pour caractériser des colloïdes par mesures successives de l'atténuation ou de l'émission de la lumière par un mélange colloïdal à au moins deux températures et à au moins une longueur d'onde. La différence entre les mesures à deux températures ou plus, ou leur rapport, fournit une mesure de la stabilité des colloïdes en fonction de la température. La quantité de certains colloïdes organiques instables lors des variations de température peut être déterminée à partir de l'amplitude de la différence entre les mesures. Pour des mélanges appropriés, la présente méthode constitue un moyen de distinguer les composants de substances à base de colloïdes. La présente méthode peut être spécifiquement utilisée pour déterminer la stabilité et la concentration de brai colloïdal ou d'une résine de bois colloïdale dans l'eau de traitement d'un procédé de production de pâte ou du papier. Dans ce contexte, il peut être utilisé pour distinguer un brai colloïdal ou une résine de bois colloïdale du talc, de l'argile, du noir de carbone ou d'autres matières de charge.
