Title
(EN) MICRONIZED SULPHUR POWDER
(FR) POUDRE DE SOUFRE MICRONISÉ
Abstract
(EN)
A process is provided to produce a micronized sulphur powder product, including the preparation of a micronized sulphur emulsion from molten sulphur and a dispersant solution, including a surfactant in a concentration less than the critical micelle concentration of the surfactant.
(FR)
L'invention concerne un procédé pour produire un produit de poudre de soufre micronisé, comprenant la préparation d'une émulsion de soufre micronisé à partir de soufre fondu et d'une solution dispersante, comprenant un tensioactif dans une concentration inférieure à la concentration micellaire critique du tensioactif.
