发明名称 Method of making a viscous aqueous liquid
摘要 A quantity of insoluble solid particles is coated with a hydratable gelling agent to produce a composition comprised of a mass of discrete solid particles which is dry and flowable. The composition is made by placing a binder on the insoluble solid particles and then, while the binder is sticky, placing a hydratable gelling agent on the sticky binder to thereby form the composition. The hydratable gelling agent on the composition, upon contact with an aqueous liquid, operates to increase the viscosity of the aqueous liquid.

主权项 1. A method of making a viscous aqueous liquid in a first location for transport to and use in a second location, said viscous aqueous liquid having insoluble solid particles suspended therein, said method being comprised of the steps of: providing a container in said first location, introducing into said container a first quantity of a dry and flowable composition and a second quantity of an aqueous liquid, mixing said first quantity of said composition with said second quantity of said aqueous liquid in said container for a time sufficient to produce said viscous aqueous liquid having said insoluble solid particles suspended therein and transporting said viscous aqueous liquid having said insoluble solid particles suspended therein; wherein: said composition is comprised of a mass of discrete solids consisting of said insoluble solid particles having a dry coating on the exterior surfaces thereof, said dry coating being comprised of a binder selected from polyvinylpyrrolidone or corn syrup and a gelling agent selected from guar gum, karaya gum, xanthan gum, gum arabic, carrageenan gum, welan gum, hydroxypropyl guar, hydroxyethycellulose, carboxymethylhydroxypropylguar or carboxymethylhydroxyethylcellulose; said gelling agent in said composition, upon contact with said first quantity of said aqueous liquid during said mixing in said container, produces said viscous aqueous liquid; and said viscous aqueous liquid has a viscosity greater than the viscosity of said aqueous liquid.
