摘要： PURPOSE:To highly concentrate a slurry and to stabilize the slurry for a long time by using an additive containing a sulfonated styrene-maleic acid copolymer or its salt and a water soluble inorganic salt (e.g. sodium carbonate) producing an anion which forms a sparingly water soluble salt by combining with a polyvalent metallic ion, as essential components. CONSTITUTION:(A) The sulfonated styrene-maleic acid copolymer or its salt (4/1) to (50/1) in polymerization molar ratio of sulfonated styrene to maleic acid and 3000-50000 in weight average molecular weight and (B) the water soluble inorganic salt (e.g. sodium carbonate) producing the anion which forms the sparingly water soluble salt by combining with the polyvalent metallic ion are incorporated as the essential components. The ratio of the component (A) to the component (B) is preferably (1/9) to (20/1). The coal-water slurry high in coal conc., stable for a long time and keeping self-flowability can be obtained by using this additive.

摘要： PURPOSE:To provide a viscosity depressant which lowers the viscosity of a coal/ water slurry and makes it possible to pump a highly concentrated coal/water slurry by adding it in a small amount, consisting of a polyether compd. (derivative) obtd. by adding an alkylene oxide to an active hydrogen-contg. amine (derivative). CONSTITUTION:An alkylene oxide such as ethylene oxide is added to an amine contg. at least one active hydrogen or its derivative, such as dimethylamine and the product is, if necessary, modified with an aicd to obtain a viscosity depressant consisting of a polyether (derivative) having an MW of 1,000-100,000. 0.01-5.0wt% said viscosity depressant is added to a coal/water slurry contg. coal at a concn. of 70wt% or above, whereby the viscosity of the slurry can be lowered to a level at which the slurry can be pumped. EFFECT:The viscosity depressant has an effect of stably dispersing coal in water.

摘要： PURPOSE:The titled viscosity depressant effective even in a small amt., which comprises a specified polyether obtd. by the addition of an alkylene oxide with a compd. having an active hydrogen atom. CONSTITUTION:A polyether of the formula (wherein Z is a residue of active hydrogen-contg. compd. such as an alcohol, amine or phenol; R is a 3C or higher alkylene oxide residue; m and n are each a number making a proportion of ethylene oxide in the total alkylene oxides 10-40wt%; x is not more than the number of active hydrogen atoms in the active hydrogen-contg. compd.) having MW of about 4,000-100,000 is used as a viscosity depressant. It is sufficient for a coal/water slurry to add about 0.01-5wt% said visocity depressant and it is possible to form a coal/water slurry of coal concn. >= about 61% and with good fluidity. The sulfate and phosphate of said polyether are also similarly effective (where a proportion of ethylene oxide in the total ethylene oxide shall be 10- 39wt%).
