The active zinc oxide for the white or the micro yellow spherical attritive powder, density 5.47g/cm3, the melting point 1800, does not dissolve in the water, dissolves in the acid, in the alkali ammonium chloride and the ammonia water. In humid air carbon dioxide production basic zinc carbonate. Its biggest characteristic is the particle size 50-100 nanometers, has in a big way compared to the indirect method zinc oxide and the direct method zinc oxide compared to the surface area, has the high-activity and the good dispersivity in the application. Active zinc oxide application 1Has the trundle to be good, the dispersive fine characteristic, its particle size is in addition small, the structure is light and is loose, the nitrogen adsorption is bigger than the surface area, causes it when serves as the curing active ingredient, in the sizing material distributes evenly, is big with the hydrogen sulfide contacted area, carries on the interface reaction opportunity to be big, in addition this product activated material helps urges the function, causes the zinc oxide to transform for the zinc sulfide conversion rate is high. Therefore as synthetic rubbers curing promoter and the good strengthening agent, is the ordinary zinc oxide amount used 50-70%. 2Serves as ultraviolet rays stabilizer in the rubber industry, can cause the polyethylene to bear the big disposition to have the good improvement. 3Has the response with the resinic acid, but makes the zinc resin which results, may use for to produce the quick-setting ink, has the good coloring function. 4Makes the zinc oxide sweetening agent, has the surface area is bigger than, the penetration sulfur allows high, the mechanical strength to be high, the stack crack is big, bed level pressure drop small characteristic. Widely applies in all becomes the ammonia, industry feed gases and so on methyl alcohol and system hydrogen, the oil depth desulphurization purification process. Under certain temperature and the pressure can the gas in the micro hydrogen sulfide, organic sulphur density effective reduction. 5Chemistry method production, the active zinc oxide is with chemistry method is the aqueous method production, the direct method or the indirect method zinc oxide equipment cannot produce the active zinc oxide. |
