本章按下述步骤对结垢及防垢,作了清楚而明确的说明:1.测定沉淀物的主要成份;2.根据上述主要成份,解释结垢原因;3.通过检验混合水或单一某种水的物理变化确定结垢原因;4.物理法防垢效果的鉴别和研究;5.如果在水源防垢无效时,应选择有效方法除垢或处理。固体沉淀,主要是由于水中溶解物之间的化学反应而产生的。因此,如果某种结垢产物的主要成份确定了,那么引起化学沉淀的主要原因也就知道了。两种不同的水混合时,混合之前就要分析和确定可能结垢的原因。纯属物理变化的过饱和所引起的沉淀情
This chapter is based on the following steps on the scaling and anti-scaling, made clear and clear description: 1. Determination of the sediment of the main components; 2. According to the main ingredients, explain the cause of scaling; 3. By testing mixed water or a single Physical and chemical changes of water to determine the cause of scaling; 4 physical method of anti-scaling effect of identification and research; 5. If the anti-scale water invalidity, should choose an effective method of descaling or processing. Solid precipitation, mainly due to the chemical reaction between the dissolved water produced. Therefore, if the major components of a certain scale product are identified, then the main cause of chemical precipitation is known. When mixing two different types of water, analyze and determine the possible causes of scaling before mixing. Purely physical changes caused by the saturation of precipitation situation
