在实验室条件下 ,用络合滴定法和标准挂片法研究一种新型天然阻垢剂的阻垢及缓蚀作用。并进一步探讨了阻垢率随阻垢剂用量、Ca2 +浓度、pH值以及溶液温度的变化关系。实验表明 :这种阻垢剂具有较好的阻垢效果 ,同时也有缓蚀作用。 Under laboratory conditions, a new type of natural scale inhibitor scale inhibition and corrosion inhibition with complexation titration and standard coupon method. The relationship between scale inhibition rate and the amount of scale inhibitor, Ca2 + concentration, pH value and solution temperature were also discussed. Experiments show that: This scale inhibitor has a good scale inhibition effect, but also corrosion inhibition.
