反滲透阻垢劑購買指南

反滲透阻垢劑是專門為反滲透(RO)系統,納濾(NF)和超濾(UF)系統設計的阻垢劑。它可以防止膜表面結垢,提高產水量和水質,并降低運營成本。

 

反滲透阻垢劑的特性。

1.在大濃度范圍內有效控制無機垢的形成;

2.請勿與氧化鋁鐵和硅化合物形成不溶物;

3.可以有效抑制硅的聚合和沉積,濃水側SiO 2的濃度可以達到290;

4.可用于反滲透CA和TFC膜,納濾膜和超濾膜;

5.極好的溶解性和穩定性;

6.給水的pH值在5-10范圍內有效。

反滲透阻垢劑的優勢。

1.可應用于各種膠片管的材料;

2.可應用于多種不同水質,仍具有較高的阻垢效率,降低了膜管的清洗頻率;

3.它可以代替添加酸的需要,以防止由于添加酸引起的可能的腐蝕問題;

4.添加量極低,具有優異的閾值功能,并且具有最大的防垢控制經濟效益。

5.對鐵,錳等金屬離子具有良好的螯合和穩定作用,防止在膜管上產生污垢。

6.產品功效和穩定性遠遠優于六偏磷酸鈉鈉或純聚合物型阻垢劑;

7.允許反滲透膜系統以更高的產水率運行。

反滲透阻垢劑的影響。

1.絡合和增溶:

反滲透阻垢劑溶解于水中后被離子化,形成帶負電荷的分子鏈,該分子鏈與Ca 2+形成水溶性絡合物或螯合物,從而增加了無機鹽的溶解度并防止了結垢。

2.晶格畸變效果:

RO阻垢劑分子中的部分官能團在無機鹽核或微晶上占據一定位置,這會阻礙并破壞無機鹽晶體的正常生長,減慢晶體的生長速度,從而降低鹽分規模。編隊;

3.靜電排斥:

反滲透阻垢劑溶解于水中后被吸附在無機鹽的微晶上,從而增加了顆粒之間的排斥力,阻礙了它們的聚結,從而使其處于良好的分散狀態,從而防止或減少了水垢的形成。規模。
