Blending method, surface

The so-called dry mixing or dry blending method has been used for the modification of" particles in the powder technology (59). In this method, surface modification of coarse particles is carried out by mixing fine particles and coarse particles with an auto ceramic mortar or with a centrifugal rotating mixer. This procedure can be applicable for the production of variety of composite magnetic particles. 

The dry impact blending method has recently been used in the investigation of surface modification techniques of particles in the field of powder technology. In... 

Researchers have templated structures in numerous classes of polymer films using a variety of methods. The next sections of this chapter will summarize two particularly important templating methods—surface chemistry templating and topographic templating— for single polymer films, polymer blends, and block copolymer films. 

When the integral blending method was used to treat a filler surface and the amount of added solution was varied to change the amount of the silane coverage, peculiar results were observed. As the amount of the added solution was increased, die quantity of the deposited silane monotonously increased as expected. However, this... 

The point of improving the properties of polymer/clay nanocomposites is how to exfoliate and well disperse individual platelets with high aspect ratios, that is, over 200, throughout the polymer matrix (Ray and Okamoto, 2003). Currently, an exfoliation mechanism for nanoclay had been proposed for the melt-blending method (Dennis et al., 2001). It was shown that as the nanoclay particles were melt blended into a polymer, the clay particles were first fractured by the shear in the extruder. The polymer chains were then diffused into the clay interlayer because of a physical or a chemical affinity between the polymer and the nanoclay surface. Finally, the chains pushed the end of the platelets apart, and an onion-like delaminating process further continued to disperse the platelets into the polymer matrix.

Many older finishes can be removed with single solvents or blends of petroleum solvents and oxygenates. Varnish can be removed with mineral spirits, shellac can be stripped with alcohols, and lacquers can be removed with blends of acetates and alcohols (lacquer thinners). The removal mechanism is one of dissolving the coating, then washing the surface or wiping away the finish. This method is often used to reamalgamate or liquefy old finishes on antique items of furniture.
