表面特性对污垢结垢行为影响研究综述

摘要

对无机盐结垢行为影响研究,多是围绕流速、温度、浓度对污垢沉积质量、诱导期和热阻的影响进行展开的.选取污垢形貌结构、附着位置、颗粒尺寸等微观结垢行为作为研究对象,综述材料表面性质(粗糙度、接触角、表面能)对微观结垢行为的影响,为从微观角度揭示不同材料表面宏观结垢行为差异提供依据;同时,对于污垢附着强度研究现状进行总结,为污垢去除以及选择合理的抗垢材料提供理论支持.%The review of the influencing factors of inorganic salt fouling behavior is mainly focused on the effects of flow rate,temperature and concentration on the mass of fouling deposition,induction period and thermal resistance.In this paper,the microscopic fouling behaviors such as morphology structure,attachment position and particle size are selected as research objects.The effect of material surface characteristics (roughness,contact angle and surface energy) on the microscopic fouling behaviors are reviewed,which can provide the basis for revealing the difference macroscopic fouling behavior of different materials surface from a microscopic point of view.At the same time,the current research status of fouling adhesion strength is summarized to provide theoretical support for the removal of fouling and the selection of reasonable anti-fouling materials.
