Abstract
Official abstract text for this publication.
Provided is a binder for a coal-containing formed product, which contains a macromolecular polymer having an intrinsic viscosity of 2.0 dl/g or higher.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coal-containing compression-formed product, comprising a binder and 50% or more by mass of coal, wherein the binder comprises an emulsion comprising a macromolecular polymer having an intrinsic viscosity of 3.0 dl/g or higher and 30 dl/g or lower, wherein a content of the macromolecular polymer in the emulsion is 20% by mass or higher and 60% by mass or lower, and the macromolecular polymer is at least one selected from the group consisting of polymers of sodium (meth)acrylate, copolymers of sodium (meth)acrylate with acrylamide, and copolymers of (meth)acrylic acid 2-trimethylaminoethyl chloride with acrylamide. 2. The coal-containing compression-formed product according to claim 1 , wherein the macromolecular polymer is at least one selected from the group consisting of polymers of sodium acrylate, copolymers of sodium acrylate and acrylamide, and copolymers of acrylic acid 2-trimethylaminoethyl chloride with acrylamide. 3. A method for producing a coal-containing compression-formed product, comprising: combining a binder with at least coal to obtain a mixture, wherein the binder comprises an emulsion comprising a macromolecular polymer having an intrinsic viscosity of 3.0 dl/g or higher and 30 dl/g or lower, and a content of the macromolecular polymer in the emulsion is 20% by mass or higher and 60% by mass or lower; and compressing the mixture, wherein the produced coal-containing compression-formed product comprises 50% or more by mass of the coal, and the macromolecular polymer is at least one selected from the group consisting ofpolymers of sodium (meth)acrylate, copolymers of sodium (meth)acrylate with acrylamide, and copolymers of (meth)acrylic acid 2-trimethylaminoethyl chloride with acrylamide.
