在循環(huán)水系統(tǒng)中，通常水垢、微生物、壓力及溫度等因素會產生一些腐蝕現象，造成設備維修頻繁，使用壽命短；為了防止鍋爐或者管道腐蝕，除了控制PH值以外，經常在水中介入一些聚磷酸鹽作為緩蝕劑，當水達到一定的溫度，聚磷酸鹽就會分解成亞磷酸鹽，如果設備有腐蝕現象，磷酸鹽水垢呈紅色。這種垢松軟，成堆積狀，但遇到高溫就會變硬。

通常鍋爐的補水，因為量小，來不及處理就會補給；通常為了吸附、卷帶水中的絮凝體，達到澄清水質的目的，通常在補水中加入活化硅酸，也叫活性硅土，導致水中的二氧化硅含量過高，在受熱的狀態(tài)下就和鈣鎂垢形成了硬度極高的硅酸鹽水垢，這種水垢是乳白色和灰色，極易腐蝕鍋爐體和管道。

HYC工業(yè)強磁除垢器、磁化除垢器能較輕易的分散各種離子，較好的預防這些垢類變硬和吸附。
