Title:
FLUIDITY IMPROVING AGENT FOR SOLID FUEL OR FOR STEEL RAW MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/120230
Kind Code:
A1
Abstract:
The present invention provides a fluidity improving agent for a solid fuel or for a steel raw material, the fluidity improving agent satisfying (1) and (2) and containing a crosslinked polymer (A) comprising, as essential constituent monomers, a water-soluble vinyl monomer (a1) and/or a vinyl monomer (a2) that becomes (a1) through hydrolysis, and a crosslinking agent (b). According to the present invention, the fluidity improving agent that can improve the fluidity of a solid fuel or a steel raw material without impairing production efficiency and yield can be provided, and a method for modifying the fluidity of a solid fuel or a steel raw material in order to improve the fluidity of the solid fuel or steel raw material without impairing production efficiency and yield can be provided. (1) Gel modulus of elasticity: 1.5-2.5 kN/m2 (2) Water retention amount: greater than 320 g/g and equal to or less than 700 g/g
