  • Patent number: 11753771
    Abstract: The invention provides a method of producing a filler comprising calcium carbonate (PCC), preferably to be used in paper or paper board production or in fibre based composites. The method of the invention comprises the steps of; —providing fly ash generated in paper or paper board production; —fractionating said fly ash in at least one step, whereby a coarser fraction is separated from a finer fraction; —forming a suspension of said coarser fraction; —adding carbon dioxide to said suspension to form precipitated calcium carbonate. The method of the invention avoids problems with high amounts of arsenic and heavy metals in the production of filler comprising PCC, when using ash generated in paper or paper board production as a raw material. It has been shown that harmful elements, such as arsenic and heavy metals, are primarily accumulated in the finer fractions of the fly ash.

    Abstract: The present invention relates to an inorganic board comprising a base layer containing magnesium-based inorganic materials and phase change materials, and to a method for producing the board. The inorganic board of the present invention employs magnesium-based inorganic materials instead of plaster used in conventional boards, and thus improves the strength and water resistance thereof as compared to conventional plaster boards. Accordingly, the board of the present invention is formed so as to be thin, and the content of the phase change materials in the base layer increases by the superior blending ratio of magnesium-based inorganic materials and phase change materials, thus maintaining the indoor temperature of the structure constructed by the board of the present invention at a comfortable level. Therefore, the inorganic board of the present invention can be effectively used in interior materials or the like for a building, which require strength and water resistance properties.

  • Publication number: 20110192319
    Abstract: Conventional toughening agents are typically rubbery materials or small molecular weight molecules, which mostly sacrifice the intrinsic properties of a matrix such as modulus, strength, and thermal stability as side effects. On the other hand, high modulus inclusions tend to reinforce elastic modulus very efficiently, but not the strength very well. For example, mechanical reinforcement with inorganic inclusions often degrades the composite toughness, encountering a frequent catastrophic brittle failure triggered by minute chips and cracks. Thus, toughening generally conflicts with mechanical reinforcement. Carbon nanotubes have been used as efficient reinforcing agents in various applications due to their combination of extraordinary mechanical, electrical, and thermal properties.

  • Patent number: 6372033
    Abstract: Powder mixtures and a method of forming and shaping the mixtures. The method involves compounding the components of powder materials, binder, solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder materials. The non-solvent is lower in viscosity than the binder combined with the solvent. The solvent is present in an amount that is less than the amount that would be present otherwise. The components are mixed and plasticized, and shaped to form a green body. The choice of components results in improved wet green strength in the green body. The method is especially useful for extrusion processing of aqueous binder systems such as water and cellulose ethers and hydrophobic non-solvents, to form structures such as honeycombs. In the body, the ratio, upon subsequent firing, of the isostatic strength to the A-axis strength is at least about 20% higher than in bodies made without the mixture composition of the invention.
