  • Patent number: 9157189
    Abstract: The invention provides a method of controlling retention on a forming fabric in a paper making process, an intermediate product for use in the method, as well as use of material for the intermediate product. For making the intermediate product at least one paper making chemical is added to a slurry of fine cellulose fibres such as micro fibrillated cellulose (MFC), the specific surface area of those fibres being larger than that of the fibres of the main fibrous suspension for paper making, causing the paper making chemical being adsorbed on the fine cellulose fibres. This intermediate product is then incorporated in the main fibrous suspension before the suspension is supplied from the paper machine head box to the forming fabric. Other paper making chemicals may be added to the fibrous suspension before or after addition of the intermediate product, so that interactions between different chemicals are prevented.

  • Patent number: 8487049
    Abstract: A process is described for recycling superabsorbent polymer fines into a process that includes treating the superabsorbent polymer fines with caustic and a polymerization step for making the superabsorbent polymer gel. The process requires treating the superabsorbent polymer fines with a caustic, followed by mixture with polymerizable monomer solution, and polymerizing the mixture of the superabsorbent polymer fines and monomer to form the aqueous fluid absorbent polymer. In the process, the fines are incorporated into the new polymer gel and become indistinguishable there from. The gel may then be comminuted into a particulate dried and then separated into a portion having a desired minimum particle size in a fines portion having less than the desired size. The particulate may then be coated with a surface crosslinking agent and surface additives and heated for surface conversion.

    Abstract: In simple form the stock comprises water, cellulose fiber, pigment or filler, a cationic, charge-neutralizing chemical, and an anionic nanoparticle. The process introduces stock components in proper order, while homogenizing them towards molecular dimensions with low surface tension catalyst and vigorous mixing. The amount of catalyst is optimized for stock dispersion, and formation of an azeotrope in the dryer section. A classical nanostructure is formed. Solids exiting the press increase by as much as 6-7%; water removal energy in the dryer section is reduced in a 40-60% range. Homogeneity is maximized by controlling the standard deviation of a convenient process parameter. The system is controlled at zero zeta potential, at the specific filtration resistance level required for maximum productivity. Chemical usage is reduced by at least an order of magnitude. The process is highly sustainable.

  • Publication number: 20020139500
    Abstract: Pulp fibers can be treated with water insoluble chemical additives resulting in a minimal amount of unretained water insoluble chemical additives present after redispersing the treated pulp fibers in the process water. One embodiment of the present invention is a method for preparing chemically treated pulp fiber. A fiber slurry is created comprising process water and pulp fibers. The fiber slurry is transported to a web-forming apparatus of a pulp sheet machine thereby forming a wet fibrous web. The wet fibrous web is dried to a predetermined consistency thereby forming a dried fibrous web. The dried fibrous web is treated with a water insoluble chemical additive thereby forming a chemically treated dried fibrous web containing chemically treated pulp fibers.

  • Patent number: 6425979
    Abstract: A binder is applied to particles which are then combined with fibers to bind the particles to the fibers. The particles have functional sites for forming a hydrogen bond or a coordinate covalent bond. The fibers have hydrogen bonding functional sites. The binder comprises binder molecules, the binder molecules having at least one functional group that is capable of forming a hydrogen bond or a coordinate covalent bond with the particles, and at least one functional group that is capable of forming a hydrogen bond with the fibers. A substantial portion of the particles that are adhered to the fibers may be adhered in particulate form by hydrogen bonds or coordinate covalent bonds to the binder, and the binder in turn may be adhered to the fibers by hydrogen bonds. Fibers containing particles bound by this method are easily densified.

  • Publication number: 20020088584
    Abstract: This invention discloses a new technology related to cellulose fiber reinforced cement composite materials using the loaded cellulose fibers. This invention discloses four aspects of the technology: fiber treatment, formulation, method and final product. This technology advantageously provides fiber cement building materials with the desirable characteristics of reduced water absorption, reduced rate of water absorption, lower water migration, and lower water permeability. This invention also impart the final products improved freeze-thaw resistance, reduced efflorescence, reduced chemical dissolution and re-deposition, and improved rot and fire resistances, compared to conventional fiber cement products. These improved attributes are gained without loss in dimensional stability, strength, strain or toughness.

  • Patent number: 6416625
    Abstract: In the manufacturing method of fluoro based polymer composite boards of the invention, which provides a fast process and high efficiency, a suitable amount of water soluble organic solvent is added to a fluoro based polymer suspension during the process of mixing ceramic powder and/or glass fiber to the fluoro based polymer suspension in order to improve the coagulation of the fluoro based polymer and ceramic powder, and to reduce the gelling time. During the process of mixing ceramic powder and/or glass fiber, the fluoro based polymer suspension and the organic solvent, a suitable amount of water can be added to control the ratio between the water and the organic solvent obtained from the mixture. The gelling time of the mixture can thus be reduced. By controlling the ratio between the water and the organic solvent obtained from the mixture, there is still enough time to allow homogeneous mixing after the gelling speed is increased.
