It adopts controlled synthesis technology to ensure product uniformity and stability. Its high purity enables rapid activation during rubber vulcanization, improving vulcanization efficiency. As a coating filler, it can improve the corrosion resistance and gloss of the coating. Low impurity content avoids negative impacts on coating performance. The environmental-friendly production process reduces industrial wastewater emissions, meeting the environmental protection requirements of industrial production, and particle size can be adjusted according to customer needs.
The product has a minimum purity of 97.0%, zinc content of 56.0% minimum, moisture content not exceeding 0.3%, iron content ≤0.02%, manganese content ≤0.01%, sulfate content ≤0.05%, lead content ≤50 ppm, particle size D50 of 30-50 μm, and appears as white loose powder with a bulk density of 0.7-0.9 g/cm³. It is packaged in 50kg woven bags, stored in a dry and ventilated environment, and has a shelf life of 2 years.
It is used as a vulcanization activator for natural rubber and synthetic rubber to improve the tensile strength and wear resistance of rubber products; as a filler for water-based coatings and powder coatings to improve the weather resistance and adhesion of the coating; as an intermediate raw material for preparing other zinc salt chemicals such as zinc oxide and zinc chloride; and as an additive for ceramic glazes to improve the gloss of the glaze surface.
