GB/T 4467-2006 "Dyes — Determination of dispersion stability of suspension" specifies the method for determining the dispersion stability of suspension for disperse dyes and vat dyes (superfine powder), applicable to the quality testing of these two types of dyes. The method involves preparing a dye suspension, allowing it to stand, then taking the supernatant and using a spectrophotometer to measure the absorbance to evaluate the dispersion stability. The testing requires instruments such as a spectrophotometer, magnetic stirrer, cylindrical glass separatory funnel, analytical balance, thermometer, etc., providing a basis for controlling dispersion effectiveness in dye applications.
