The composite material includes particles of at least one light scattering material, the surface of which is essentially covered by at least one water-insoluble polysaccharide material. The invention also relates to a method for the preparation of the composite material. Further, the invention relates to a paper and board manufacturing process, in which said composite materials are employed as manufacturing materials. Both highly organic end products with exceptional heat capacities and cheap, high filler end products can be manufactured. The invention also relates to a method for improving retention of light scattering filler material in the manufacture of paper and board.Type: ApplicationFiled: March 15, 2006Publication date: August 27, 2009Inventors: Vesa Myllymäki, Reijo Aksela, Anna Sundquist, Saila Karvinen

Publication number: 20090075093Abstract: The invention relates to a method and compositions for producing a hydrophilic coating on a surface of a solid material. The method comprises a cleaning step and a coating step. The cleaning step may be preceded by an initial cleaning step and it may optionally be succeeded by a preconditioning step prior to the coating step. The cleaning step comprises cleaning and preconditioning a surface of a material by use of a first cleaning fluid composition comprising ceria (CeO2) particles. The coating step comprises treatment by use of a coating fluid composition comprising photocatalytically active nanoparticles of titania (TiO2). An advantage of the method of the invention is that the method may be carried out at temperatures in the range 5 to 50° C. No further heating is required. Thereby, the method may easily be used for treating materials such as windows, furniture, tiles, walls, etc.Type: ApplicationFiled: August 14, 2008Publication date: March 19, 2009Applicant: SCF Technologies A/SInventors: Steen Brummerstedt Iversen, Henrik Jensen, Morten Foverskov, Ramona Mateiu

Patent number: 7449429Abstract: An initial chemical composition comprising selected surfactants, dispersants, and degreasers that liquefy, disperse, demulsify, degrease, inhibit corrosion and scale formation, and lower the pour point of a petroleum, coal, Fischer-Tropsch synthesized, or naturally occurring paraffin-based wax and asphaltene. Such a product is capable of converting crystalline wax (paraffin) in, for example, slop oil into an amorphous form of wax at room temperature, allowing the wax to be dissolved in, for example, crude oil without the need for heating, and maintaining it in solution at room temperature, substantially reducing, indeed in some applications, preventing, for example, wax build-up in pipelines, processing and transportation equipment, etc., and the recovery of the hydrocarbons in the slop oil. In a second aspect of the invention, the pre-blend addition of a hydrotrope-demulsifier, a chelating agent and a wax plasticizer can result in a BS&W of zero for the recovered hydrocarbon blend.Type: GrantFiled: August 30, 2004Date of Patent: November 11, 2008Assignee: Malcera, L.L.C.Inventor: Gordon K.
