  • 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.

The process involves exposing a quantity of eggshell to high air speed at room temperatures to pulverize the eggshell and separate the eggshell component from the inner membrane component. Thus, the process avoids the use of high temperatures and other harsh chemical treatments to remove the inner membrane from the eggshell thereby resulting in an eggshell material that retains the original lipid-protein structure of the native eggshell from which the powder derives. Accordingly, an eggshell powder composition is provided that is substantially free of inner membrane material and possesses a lipid-protein structure substantially similar to that of the eggshell from which the powder is derived.

  • Publication number: 20140209841
    Abstract: A biodegradable bio-plastic material composition comprising of synthetic materials and biological/natural/second natural reusable material is described. The use of natural material that is easily degradable in landfill makes it easy to dispose the article and reduce green gas emission in the environment. Biological reusable materials may be one of polylactic acid based plastic, walnut, almond, coconut and other hard shells, hard skins from rice, wheat, flax, and other seeds, corn husks, and other organic biodegradable matter and synthetic materials may be polypropylene and/or polyethylene.

  • Patent number: 8722092
    Abstract: The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 nm. These nanoparticles are produced from amorphous cellulose or by amorphization of cellulose, optional subsequent hydrolysis and by input of energy into a water-containing medium after or during dispersion.

  • Patent number: 8703847
    Abstract: The present invention is directed to a method for preparing a cellulose reactive adduct of polyvinylamide and a composition resulting from the method. The preparation of the cellulose reactive adduct is carried out close to a Critical Concentration defined herein. When the reaction is run close to this Critical Concentration, the risk of gelation is minimized, consumed glyoxal is maximized, and shelf live is enhanced. Additionally, the glyoxalated vinylamides of the present invention impart improved wet and dry strengthening efficiency to paper and paperboard when compared to adducts disclosed in previously described art.
