ポリ塩化アルミニウム (PAC) の主要な品質指標

2026,01,13
ポリ塩化アルミニウム (PAC) は、水処理における重要な化学薬品です。そのパフォーマンスは主に次の主要な品質指標によって決まります。

1.基本性
塩基性とは、PAC 構造内のヒドロキシル化の程度またはヒドロキシル基の含有量を指します。これはポリマーの重合レベルを示す重要なパラメーターです。この指標は凝集・凝集効率と密接に関係しており、PAC の最も重要な特性の 1 つです。一般に、汚染物質濃度や塩分濃度が高い原水を処理する場合、塩基度が高いほど凝集性能が向上することがよくあります。

2. pH値
PAC 溶液の pH 値も重要な指標です。一般に、塩基性度が上昇すると、pH も上昇します。同じ塩基度の PAC 溶液でも、濃度が異なると異なる pH 値を示す可能性があることに注意することが重要です。

3. アルミナ含有量(Al₂O₃含有量)
アルミナ (Al2O3) 含有量は、PAC 中の有効成分の濃度を表します。この含有量と溶液の相対密度の間には一般的な相関関係があります。通常、相対密度が高いほど、Al2O3 含有量が高いことを示します。この指標は、必要な有効量と全体的な治療効果に直接影響します。
