Abstract
PURPOSE: To prepare the titled composition having specific particle diameter and useful as a low-toxic and pollution-free anticorrosive pigment, by reacting zinc phosphite with zinc white under the condition of forced diffusion.
CONSTITUTION: Zinc phosphite is mixed with zinc white at an H2PHO3/ZnO molar ratio of 0.5W1, and made to react with each other (ZnO+H2PHO3→ ZNPHO3+H2O) under the condition of forced diffusion (e.g. high speed agitation at 3,000W10,000rpm, 28W400kHz ultrasonic vibration, high speed shearing stress, etc.) to obtain a composition containing zinc phosphite[general name, ZnPHO3. (0.02W1)ZnO, average particle diameter is 0.02W10μm]. The composition is used as an anticorrosive pigment as it is, or after wet pulverization, drying and pulverization.
USE: Rust prevention of food-relating apparatus (refrigerator, freezer, electronic oven, and other kitchen apparatuses), food industry, toys, etc.
