Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a scale inhibitor which has a high calcium scale prevention effect.SOLUTION: A scale inhibitor contains a polymer (A) containing a (meth)acrylic acid (a1) and a (meth)acrylate (a2) as essential constituent monomers and has a neutralization degree (X) of (A) of 95-99%, determined by numerical expression (1): neutralization degree (X)(%)={1-S/(S+T)}×100, where S is the mol number of carboxyl groups in (A); and T is the mol number of carboxylates in (A).
【課題】カルシウムスケール防止効果の高いスケール防止剤を提供することを目的とする。【解決手段】(メタ)アクリル酸(a1)及び(メタ)アクリル酸塩(a2)を必須構成単量体とする重合体(A)を含むスケール防止剤であって、下記数式(1)により求められる(A)の中和度(X)が95〜99%であるスケール防止剤。中和度(X)(%)={1−S/(S+T)}?100 (1)[数式(1)中、Sは(A)中のカルボキシル基のモル数を表し、Tは(A)中のカルボン酸塩のモル数を表す。]【選択図】 図1 |
