    摘要: Processes for producing supported zinc dimolybdate hydroxide/silica complexes include the steps of reacting a zinc compound (such as zinc oxide) and molybdenum trioxide in an aqueous system to form a reaction mixture, and contacting the reaction mixture with silica to form the supported zinc dimolybdate hydroxide/silica complex. The resulting supported zinc dimolybdate hydroxide/silica complexes contain silica and zinc dimolybdate hydroxide at an amount in a range from 3 to 20 wt. % zinc, and generally, at least 80 wt. % of the zinc dimolybdate hydroxide is present in the form Zn3Mo2O8(OH)2. These supported zinc dimolybdate hydroxide/silica complexes are useful in polymer compositions, such as PVC-based and epoxy-based formulations.

    摘要: Methods are provided for beneficially reusing a paint-saturated filter aid, such as paint-saturated alkaline earth metal carbonates, as a substitute in applications requiring virgin alkaline earth metal carbonates. The paint-saturated filter aid is prepared by re-milling paint-saturated filter aid to a predetermined size to produce re-milled particles suitable for reuse in a variety of applications, including flooring, concrete, and the like. Also provided are flooring materials including re-milled particles of a paint-saturated filter aid characterized by one or more of: a median particle size (D50) of about 1 to about 50 microns; less than about 5% of the re-milled particles being retained on a 200 mesh screen; or a top cut size (D90) of about 5 to about 300 microns.
