PURPOSE:To obtain binder giving pellets having steeply improved surface and fastening, etc., without any tackiness by co-using sodium CMC crosslinked with acid-type CMC and a small amount of sodium polyacrylate. CONSTITUTION:Sodium carboxymethyl cellulose (sodium CMC) crosslinked with acid-type carboxymethyl cellulose 9acid-type CMC) is co-used with sodium polyacrylate to afford the aimed binder. Adding amount of sodium polyacrylate is preferably 0.5-10wt.% to crosslinked CMC. In a case of <=0.5wt.% of the adding amount, effect of the binder is not extreme and in a case of >=10wt.%, tackiness specific to sodium polyacrylate inversely begins to exhibit and also hardness is reduced. In said binder, generally used other paste, e.g., guar gum or sodium alginate may also be co-used. |
