阅读说明：本技术 管道防腐涂层加工方法 (Processing method of pipeline anticorrosive coating ) 是由 刘艳胜 张永胜 张玉林 李伟 于 2020-06-29 设计创作，主要内容包括：本发明提供了管道防腐涂层加工方法,属于管道涂层技术领域,包括：对铸铁管的表面进行预处理,并达到预设标准。将将外侧面喷涂有面漆的不锈钢卷材包裹在铸铁管上,并不锈钢卷材的内侧面与铸铁管粘接固定。沿不锈钢卷材的侧边涂抹阻隔胶。本发明提供的管道防腐涂层加工方法中面漆可预先喷涂在不锈钢卷材上,待铸铁管预处理完成后可在较短的时间内将不锈钢钢卷材粘接在铸铁管上,相较于传统的将不锈钢卷材和面漆依次喷涂在铸铁管相比,面漆的喷涂和铸铁管的预处理可以独立进行,并且通过包裹方式相比喷涂不仅提高了防腐的效果,同时提高了工作效率,并且减少了资源的浪费和成本的投入。(The invention provides a processing method of an anticorrosive coating of a pipeline, which belongs to the technical field of pipeline coatings and comprises the following steps: the surface of the cast iron pipe is pretreated and reaches a preset standard. And wrapping the stainless steel coiled material with the outer side surface coated with the finish paint on the cast iron pipe, and adhering and fixing the inner side surface of the stainless steel coiled material and the cast iron pipe. And coating barrier glue along the side edge of the stainless steel coiled material. The finishing paint can be sprayed on the stainless steel coiled material in advance in the processing method of the pipeline anticorrosive coating, the stainless steel coiled material can be bonded on the cast iron pipe in a shorter time after the pretreatment of the cast iron pipe is finished, compared with the traditional method that the stainless steel coiled material and the finishing paint are sprayed on the cast iron pipe in sequence, the spraying of the finishing paint and the pretreatment of the cast iron pipe can be carried out independently, and compared with the spraying in a wrapping mode, the spraying method not only improves the anticorrosive effect, but also improves the working efficiency, and reduces the waste of resources and the investment of cost.)
