课程名称：防护涂层与涂料腐蚀控制 课程概述：在大气、水体和土壤中，未经保护的钢材容易发生腐蚀，可能导致损坏。因此，为了避免腐蚀损害，钢结构通常需要采取保护措施，以抵御在使用寿命期间所承受的腐蚀压力。本课程重点讨论通过涂料系统进行的保护，涵盖各个方面，以确保实现足够的腐蚀保护。防护涂层的检查人员和涂料材料的制造商将能够获得关于涂料系统腐蚀保护的最新、简明的信息。这些信息必须尽可能全面、明确且容易理解，以避免在保护工作实际实施过程中出现困难和误解。 课程内容将从腐蚀的基本概念入手，解释基本腐蚀电池，随后介绍涂层保护理论，包括屏障效应、抑制剂效应和电偶效应。课程还将深入探讨涂料的组成（如粘结剂、颜料、溶剂和添加剂）、涂料的固化和干燥机制（包括氧化干燥、物理干燥/溶剂蒸发、化学固化以及红外/紫外线固化）。此外，课程将介绍涂料系统的构成，其由一层或多层涂料组合而成，提供腐蚀保护。 其他主要内容包括表面准备技术，如干喷砂清理、湿喷射、手工和电动工具清理、火焰清理、酸洗（化学清洗）、蒸汽脱脂和天气化。课程还将涵盖涂料的应用、质量控制以及施涂前、施涂中和施涂后的检验，最后讨论涂料失效的原因。 本课程旨在为参与者提供全面的防腐涂料应用知识，帮助他们在相关领域中更好地开展工作。
Unprotected steel in the atmosphere, in water and in soil is subject to corrosion that may lead to damage. Therefore, to avoid corrosion damage, steel structures are normally protected to withstand the corrosion stresses during the service life required of the structure. This course deals with protection by paint systems and covers, in the various parts, all features that are important in achieving adequate corrosion protection. Inspectors of protective coatings and manufacturers of coating materials to have at their disposal state-of- the-art information in concise form on corrosion protection by paint systems. Such information has to be as complete as possible, unambiguous and easily understandable to avoid difficulties and misunderstandings between the parties concerned with the practical implementation of protection work.• Our course will start with small introduction about corrosion explain basic corrosion cell followed by coating protection theory though Barrier effect, Inhibitor effect and Galvanic effect.• Paint composition (Binder, Pigments, Solvents, Additives), paint curing and drying mechanism by Oxidatively drying, physically drying / Solvent Evaporation, chemically curing, and IR/UV - cured.• A paint system is one or more layers of paint, which will give corrosion protection• surface preparation by Dry abrasive blast cleaning, Wet blasting, Hand and power tool cleaning, Flame cleaning, Pickling (chemical cleaning), Vapor degreasing, Weathering• Paint application, Quality control and inspection before, during and after application and finally paint failure
