摘　　要：研究了烟柴杆提取物提取方式对阻垢性能的影响,以水作溶剂所得烟柴杆提取物对碳酸钙、硫酸钙和磷酸钙均有较好的阻垢效果。通过红外、XRD、SEM对烟柴杆提取物阻垢机理进行研究,认为所得提取物对沉积物质具有阻垢性能是其螯合作用和晶格畸变作用的协同表现。采用旋转挂片法和极化曲线对提取物缓蚀机理进行分析,烟柴杆提取物作为碳钢缓蚀剂,属于阳极型的缓蚀剂。由于烟柴杆提取物具有优良的生物降解性,所以是一种对环境友好型的水处理剂。The effect of different extraction methods on scale inhibition of tobacco rob extract was studied. The extract had good inhibition performance for calcium carbonate, calcium sulfate and calcium phosphate. The scale inhibition mechanism was studied with IR, XRD and SEM. The extract had good scale inhibition performance for deposition because of collaborative features of chelation function and distortion function. The method of rotary coupon test and polarization curve were used to study corrosion inhibition mechanism of tobacco rob extract. The extractor was an anodic corrosion inhibitor for carbon steel. The tobacco rob extract was an environment-friendly water treatment agent with excellent biodegradability.
