部分皂化腐植酸的制备及清防垢性能评价

Preparation of partial saponification humic-acid and anti-scaling performance valuation

通过控制NaOH溶液浓度、HA与NaOH反应物料比例,采用腐植酸与NaOH溶液直接接触的方式,抽取多种部分皂化腐植酸。按照钙垢沉淀法和沉淀重量法进行防垢和清垢评价,并找出清防垢一体效果最佳的方案,其防钙垢率80%以上,钙垢溶解率也接近80%。

Multiple saponification humic-acid were extracted by humic-acid direct contacting with Na OH so-lution by controlling the concentration of Na OH solution, material ratio of HA and Na OH. The calcium scale pre-cipitation method and sediment weight method were combined for antiscaling and scale clean evaluation. The best project for anti-clean scale was put forward. The calcium antiscale rate was above 80%, the solubility was close to80%.
