In addition,the un qualified injected water will cause the gathering and transporting systems and borehole to be corroded and will form scale in them, which will greatly reduce the waterflood effect.

此外，不合格的注入水还会引起集输系统和井筒的腐蚀与结垢，从而大大降低注水效果。

In the initial stage of scale,the amendatory coefficient is the greatest.

随着结垢过程的进行，修正值增大，修正系数减小。

Three methods of physical modification, calcification and amidation were used to improve the rigidity of oxidized wax,and their technical conditions,advantages and disadvantages were studied and summarized respectively.

通过物理改性、钙化、酰胺化3种方法来提高氧化蜡的硬度，研究了其工艺条件，讨论了3种方法的优缺点。采用模拟燃煤烟气方法，研究了石灰湿法燃煤烟气脱硫过程中CO2钙化问题，指出了烟气脱硫过程中CaCO3的生成量与脱硫液初始pH值、SO2初始浓度、温度的关系，得出抑制CaCO3生成的条件，为减缓石灰湿法燃煤烟气脱硫存在的结垢现象，对石灰湿法燃煤烟气脱硫系统的实际应用具有一定的指导和借鉴价值。

Some countermeasures are taken to solve the problems, such as the smaller pipeline diameter (108 mm), poorer water quality, more serious scale deposit and lower pump capacity, which are resulted from the panel cooler for concentrated sulfuric acid (32m2) instead of the calandria type cast-iron cooler for enlarging productive capacity (from 20kt/a to 40kt/a).

在硫酸装置扩能时(由20 kt/a改为40 kt/a)，选用板式浓硫酸冷却器(32m2)代替原铸铁排管冷却器。使用中发现管路直径偏小(￠108mm)，水质差结垢严重，硫酸泵扬量选择偏小等问题。提出改进措施。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
