Abstract

L'invention concerne un procédé de préparation d'une poudre mouillable pesticide, laquelle comprend les étapes consistant à : sélectionner d'abord un dispersant à haute performance pour préparer une suspension à teneur moyenne ou élevée en pesticide ; puis ajouter un dispersant hydrosoluble résistant à haute température et un délitant hydrosoluble au système de suspension pour le mélange par cisaillement ; puis réaliser un séchage par pulvérisation pour obtenir un produit de poudre mouillable. Le procédé est principalement approprié pour des systèmes de pesticides originaux qui sont difficiles à préparer comme suspensions à haute teneur, tels des pesticides originaux à bas point de fusion ayant un point de fusion inférieur à 80 °C, des pesticides originaux fortement hydrosolubles ayant une hydrosolubilité supérieure à 0,5 g/L, et des pesticides originaux formant facilement des liaisons hydrogène et des agrégats d'eau avec de l'eau. Le procédé permet d'améliorer le rapport de la teneur en matières solides dans une bouillie préparée en suspension pendant la préparation de la poudre mouillable, de réduire la consommation d'énergie pour le séchage par pulvérisation, et d'augmenter le taux de granulation et la taille des particules de la poudre mouillable.
