  • Patent number: 11926762
    Abstract: The present disclosure provides a high-temperature nano-composite coating and a preparation method thereof, and a small bag flexible packaging coating. The high-temperature nano-composite coating provided by the present disclosure controls the fiber length. Moreover, high-temperature reinforcing filler and high-temperature expansion filler are introduced, to make the coating have ultra-high strength at high temperature without cracks caused by shrinkage at high-temperature. In addition, nanopowder, high-temperature skeleton filler and other additives are introduced to make the coating be uniform and stable and reach a slurry state similar to toothpaste. There is no precipitation and stratification during the placement process. Small packaging can be realized to facilitate construction and operation. Besides, the coating has a good bonding to furnace lining, and will not fall off from the furnace lining, thereby prolonging the service life of the furnace lining.

  • Patent number: 11370957
    Abstract: Disclosed herein is a copolymer concentrate in a bio-solvent that can be further diluted into a slurry composition. The bio-solvent facilitates the formation of a viscosified base fluid with the mixing being carried out in a short period of time and at ambient, providing a free flowing, pumpable, and dispersible slurry. The slurry is characterized as having excellent stability, maintaining suspension over a wide range of temperatures. In embodiments, the bio-solvent is selected from terpene and terpene-derivative-containing solvents, fatty acid alkyl esters, and mixtures thereof. The bio-solvent can be first mixed with a styrenic diblock copolymer to form a concentrate prior mixing with a hydrocarbon solvent, forming a viscosified base fluid for subsequent mixing with a water-soluble polymer to form the slurry. The bio-solvent can also be used to dilute the hydrocarbon solvent, prior to mixing with the styrenic diblock copolymer to form the viscosified base fluid.

  • Publication number: 20080227892
    Abstract: Paint formulations that exhibit improved performance characteristics due to the presence of a combination of a cellulose ether (carboxymethylcellulose and/or hydroxyethylcellulose) and a network building polymer (gellan gum, carrageenan, etc., as examples) as a thickening system therein are provided. Such a combination permits long-term shelf stability of the paint formulation while simultaneously according effective flow, leveling, and other important properties to the final paint formulation. The combination of the cellulose ether and a network building polymer allows for a lower viscosity cellulosic compound to impart the desired rheological behavior therein while also permitting the other desirable characteristics noted above. Such paint compositions also exhibit improved atomization for spray applications with such a thickening system.

  • Patent number: 7425589
    Abstract: The invention relates to a method for modifying cellulose ethers. The inventive method is characterised in that a cellulose ether having a humidity content of between 5 and 90% is intensively mixed with between 0.1 and 5 wt. %—in relation to the dry cellulose ether—of an additive or an additive mixture in the form of an aqueous or organic suspension or solution, at temperatures of between 20 and 100° C., and the mixture obtained is then dried.

  • Patent number: 7371279
    Abstract: A composition comprising cellulose ether, a superplasticizer and defoamer suitable for use as an additive in extruding inorganic compositions is disclosed. The inventive composition functions as a water retention agent, plasticizer and lubricant in the extrusion of inorganic compositions. The use of the inventive composition in the extrusion of building materials leads to improved processing properties, to a higher surface quality and product properties of the extruded article.

  • Patent number: 7214728
    Abstract: A size composition for the surface sizing of paper, board or other suchlike. The size composition comprises a size fraction which comprises a water-soluble, principal component made up of, for example, starch, polyvinyl alcohol, carboxymethyl cellulose, glucomannan, protein, or mixtures thereof, and a pigment fraction formed by mixing together a mineral material, which in the main comprises talc particles and/or other phyllosilicate particles, and a binder such as a synthetic polymer, latex and/or other corresponding binder. The size composition is prepared by mixing together the said size fraction and pigment fraction.

  • Patent number: 7108744
    Abstract: CMC with CMDS greater than or equal to 0.76, optionally with a non-ionic co-thickener or a CMC with CMDS less than 0.75 is used as both the rheology modifier and partial clay substitute in tape joint compounds. This significant reduction of clay level is sufficient to eliminate most of the negative characteristics of clay in joint compound.
