material dispersion
1.Earthworms are used at Nutrilite because they help to aerate the soil, speed up decomposition of plant material plowed back into the soil, add natural humus material called castings and break up water channeling through tunnels for dispersion.
2.The effect of the catalysts, e.g., concd. sulfuric acid, p-toluenesulfonic acid, dodecylbenzenesul-fonic acid on the esterification of starch was studied with cassava starch as the raw material, acetic anhydride as the esterifying agent and acetic acid as the dispersion medium.
3.When doped with Li2O, the maximum dielectric constant of this material is 28640, which is higher than that of pure PMN-10PT, while the degree of frequency dispersion and DPT are decreased.
4.A colloid in which the disperse phase has combined with the dispersion medium to produce a semisolid material, such as a jelly.
5.In the present paper, the silver-intermediate in development process of PTG material-disilver phthalate (Ag2PA) was prepared by the liquid deposition method, and Ag2PHZ2PA·H2O complex was synthesized successfully by liquid dispersion means using Ag2PA and phthalazine (PHZ) as the reactants.
6.Energy dispersion x-ray fluorescence spectrometer (EDXRF) is an important nuclear analysis tool, which is widely used in the fields of geology, metallurgy, architectural material and environment.
7.The dispersion equation for the diffractive optical element is first derived from the grating diffractive theory and the design equation for the hybrid refractive /diffractive achromatic telescope objective with only one optical material is further derived.
8.This article describes the mixing principle of bulk molding compound, three types of agitator construction and pattern used in the double arm mixer. The 180°spiral agitator and Banbury agitator are recommend for its high dispersion and effective mixing with less damage of the glassfibre in BMC material, which are the concerns in BMC manufacture.
