防腐处理


1、沥青漆涂层

      沥青漆涂层是用于输送燃气的管道。喷漆前对管子进行预热可以提高沥青漆的附着力,加速干燥。


2、水泥砂浆内衬+特殊涂层


      这种内防腐措施适用于输送污水的管道,可以提高内衬的抗腐蚀能力。


3、 环氧煤沥青涂层


       环氧煤沥青涂层既适用于燃气管道,也适用于污水管道。它是一种双组分涂层,该涂层具有较高的附着力和非常光滑的表面


4、环氧陶瓷内衬


      环氧陶瓷内衬适用于污水管道和燃气管道,但是由于制造工艺难度大,成本高,所以在使用上有一定的局限性。环氧陶瓷内衬具有很高的附着力和光洁度,是一种极好的防腐蚀涂层。


5、铝酸盐水泥涂层或硫酸盐水泥涂层


      这两种特殊水泥涂层均适用于污水管道用球墨铸铁管的内防腐,提高抵抗污水中酸碱成分的侵蚀能力。


6、聚氨酯涂层


     是一种为适应环保需求而研制开发的一种新型绿色特殊涂层,有良好的耐磨和耐腐蚀性。

Antiseptic treatment




1. Bituminous paint coating




Asphalt coating is used for gas pipeline. Preheating the pipe before spraying can improve the adhesion of asphalt paint and accelerate the drying.




2. Cement mortar lining + special coating




This kind of internal anti-corrosion measures is suitable for the pipeline conveying sewage, and can improve the anti-corrosion ability of the lining.




3. Coal tar epoxy coating




Epoxy coal tar pitch coating is suitable for both gas pipeline and sewage pipeline. It is a two-component coating with high adhesion and very smooth surface




4. Epoxy ceramic lining




Epoxy ceramic lining is suitable for sewage pipeline and gas pipeline. However, due to the difficulty of manufacturing process and high cost, it has certain limitations in use. Epoxy ceramic lining has high adhesion and smooth finish, which is an excellent anti-corrosion coating.




5. Aluminate cement coating or sulfate cement coating




These two kinds of special cement coating are suitable for the internal anti-corrosion of nodular cast iron pipes used for sewage pipes to improve the corrosion resistance of acid and alkali components in sewage.




6. Polyurethane coating




It is a new green special coating developed to meet the needs of environmental protection, with good wear resistance and corrosion resistance.
