METHOD FOR BARIUM SULFATE AND/OR CALCIUM OXALATE SCALE CONTROL

摘要

Methods of Controlling the formation of calcium oxalate and/or barium sulfate scale in aqueous systems are disclosed. The methods comprise adding from about .1 to 500 ppm of a water soluble (meth)acrylic acid/allyl ether copolymer to the desired water system. The methods are especially well adapted for use in pulping and paper making systems wherein calcium oxalate and/or barium sulfate is often encountered as a troublesome scale forming compound.
