    Abstract: Methods and systems for forming densified lignocellulose biomass are described. Methods can include torrefaction and densification of a lignocellulose feedstock. Temperature and pressure control and lubricant addition throughout the process can provide for the lignin to dissipate more completely throughout the biomass and better coat the cellulose. The product can include a high level of lignin and low volatiles, both of which can improve the energy density of the product. In addition, the process can include a cooling step that can increase the crystallinity of the solidified lignin, which can further increase bulk density and improve grindability of the product.

    Abstract: A composition comprising a fluid, and a material dispersed in the fluid, the material made up of particles having a complex three dimensional surface area such as a sharp blade-like surface, the particles having an aspect ratio larger than 0.7 for promoting kinetic boundary layer mixing in a non-linear-viscosity zone. The composition may further include an additive dispersed in the fluid. The fluid may be a thermopolymer material. A method of extruding the fluid includes feeding the fluid into an extruder, feeding additives into the extruder, feeding a material into the extruder, passing the material through a mixing zone in the extruder to disperse the material within the fluid wherein the material migrates to a boundary layer of the fluid to promote kinetic mixing of the additives within the fluid, the kinetic mixing taking place in a non-linear viscosity zone.

  • Publication number: 20150119502
    Abstract: Disclosed therein are wood plastic composites and a manufacturing method thereof, which can provide a high discoloration resistance by removing lignin from wood flour which is a main material of the wood plastic composites. The method of manufacturing wood plastic composites includes the steps of: removing lignin contained in wood chips through a cooking process of high temperature and pressure; crushing the wood chip from which lignin was removed in order to produce wood flour; putting and mixing polymer resins and additives into the wood flour so as to manufacture mixture of a gel phase; and extrusion-molding, injection-molding or compression-molding the mixture to manufacture wood plastic composites. The wood plastic composites and the manufacturing method thereof can prevent decoloration and after-yellowing even though the wood plastic composites are exposed to UV or moisture for a long time to thereby enhance long-term weather resistance.

  • Patent number: 8951634
    Abstract: The present invention relates to a filler material for a floor, comprising a natural base material and a mixture containing loess and a resin in powder or pellet form, as well as to a method for producing the filler material. The filler material of the present invention uses the natural base material and is thus environmentally-friendly and not harmful to the human body. Further, in the event rice husks are used as the natural base material, a person slipping on the floor is protected from burning caused by friction as the rice husks have a high moisture content. In addition, the loess contained in the filler material keeps the floor from becoming moldy and emits far infrared radiation, and therefore is beneficial to the human body. The resin emulsion of the filler material prevents the natural base material from generating dust, thus preventing dust from entering the human body via the respiratory organs of the human body.
