考察了不同质量浓度的NaOH溶液对高岭石和蒙脱石的成垢影响，分析了两种矿物经NaOH溶液浸泡前后的X衍射图谱，并测试了碱溶液与两种矿物作用时，液相中Si4+，Al3+的质量分数随时间的变化. 结果表明，只有在NaOH质量浓度为12.00 g/L，反应时间超过13 d时，在高岭石矿物中，才有含Si,Al元素的无定型新垢生成；蒙脱石矿物在各种质量浓度的碱溶液中都生成有序钙长石垢，其分子式是：Ca(Al2Si4O12).

The paper investigates kaolin and montmorillonite for scale buildup over a suitable range of concentration of sodium hydroxide. Before and after two mineral react with NaOH X-ray diffraction spectrum were taken and analyzed, and change of the mass fraction of Si4+ and Al3+ in liquid phase by time were also tested. It turns out that noncrystalline scale containing silicon and aluminium was formed, only at concentration of sodium hydroxide being 12.00 g/L and reaction time being over 13 d. Mineral containing montmorillonite formed order calcium feldspar scale whose molecular formula is Ca(Al2Si4O12).
