The preparation of white carbon black prepared with industrial wastes

Silica is a general term for synthesis of hydrated silica and silicates, including precipitation, SiO2 gas SiO2, CaSiO3, MgSiO3, Al23 etc.. Because of the similar performance with the carbon black and white color, so called white carbon black.
White carbon black production process of precipitation method and gas phase method, compared the two, prepared by the gas phase method of white carbon black performance is good, but precipitation method because of the cost advantage, technology is more mature, the utilization of industrial waste residue for the preparation of white carbon black by and precipitation method. System performance with traditional industrial prepared silica prepared almost, but has a large cost advantage.
SiO2 powder prepared from industrial waste slag silica basic process to get loose, as the floc after acidification of water glass. That is, water glass and acid reaction precipitation, filtration, washing, drying to obtain SiO2.
Industrial waste in preparation of white carbon black of one of them is using iron slag and copper slag water preparation of white carbon black, the method is to iron slag and copper slag as raw material, by sulfuric acid hydrolysis separation to obtain the hydrated silicic acid mixed solution, pH value adjustment, control 8 ~ 9, after removing impurity, aging, mixed in a solution of silicate hydrate of polycondensation reaction, then separated, washed, dried white carbon black. This method not only has low cost and benefit, but also can realize high added value of solid emission. It has good environmental benefit and ecological benefit.
The preparation of white carbon black can be used in rubber production and application of plastics, paints and coatings and painting medium. Iron slag preparation of white carbon black process has been successfully developed in the laboratory, and there is a long way to industrialization. White carbon black market at around 7500 yuan per ton, general production of a large steel mills, iron slag in 200 million tons. Can foresee iron smelting slag of a new way of utilization, benefits will be considerable.
