Product Name： |
Zinc oxide（indirect method） |
Other Names： |
zinc white/ lead powder |
Properties： |
White hexagonal crystal or powder, non-toxic, smell-less. It's the intermediate oxide, dissolves in acid, alkali and ammonium chloride solution, does not dissolve in water and ethyl alcohol. Can absorb the carbon dioxide and the water in the air.
Heats up to 1800 ℃, it can sublime, when high temperature assumes the yellow color, when cooling gets back to the white color, because it has the alkalinity, thus may modulate the coating with the oil class, more stronger coloring strength and covering strength. |
Use： |
In the vulcanization process, it can react with the organic promoter, stearic acid, etc to form the zinc stearate, can strengthen the cured rubber's physical performance, also can be used as the vulcanization activator, reinforcing agent and the coloring agent for natural rubber, synthetic rubber and rubber latex. Uses in the paint, printing ink and the varnished cloth for coloration. Uses as the dye printing reserving agent in the printing industrial used by , uses in the matches for neutralizing the oxhide gelatin's acidity and improving the gluing effect. In the pharmaceutical industry serves as the adhesive plaster raw material. In addition, uses in the production of pigment zinc chrome yellow and zinc acetate, zinc carbonate, zinc chloride and so on, also uses as the catalyst when synthesizing methyl alcohol, the desulfurizer when synthesizing ammonia; And uses in the production of glass and glazes, uses in the electronics industry for manufacturing the lightning arrester electric resistor and varistor and so on. |
