    摘要： A simulated wood product such as decking, fencing and architectural trim of the type heretofore made from a plastic with a natural wood powder as filler, wherein at least most, if not all, of the wood powder is replaced by a powder formed from a hard naturally occurring mineral, such as nepheline syenite or feldspar.

    摘要： An ultra-fine powder formed from a naturally occurring mineral or rock material and having a controlled or “engineered” particle size distribution (PSD) to match the infrared spectra with a maximum particle size in the range of 14-17 microns measured as either D99, or preferably D95, and a minimum particle size D5 in the range of 4-7 microns. Preferably the maximum particle size is about 15 microns, the minimum particle size is about 5 microns and the D50 particle size is about 8-10 microns with the moisture content of the particle size “engineered” powder being less than about 0.20 percent by weight and preferably about 0.05 to 0.08 percent by weight of the powder. This specially “engineered” ultra-fine powder is used to reduce the thermicity of thermal film to a value less than about 20%.

    摘要： A system for adding dust control solution to a vertically falling first stream of a substantially dry particulate proppant, where the first stream has effective diameter, the system including a stationary, generally horizontal, deflector plate with drop-off edge, the plate mounted into the stream whereby the proppant collides with the plate and cascades from the plate around the drop-off edge to create a second stream of the particulate proppant having the general shape of the drop-off edge with a stream thickness and nozzles for spraying dust control solution into the second stream.
