[0002] Surface metallization of flexible materials is of great significance to many industries and application fields such as electronics, optics and optoelectronics, aerospace, medical biology, and automobile transportation. In the surface metallization process, chemical plating usually occupies an important position. In the chemical plating process, there are still some process challenges for the treatment of continuous materials such as membrane materials, fiber materials, and sheet rolls, including process discontinuity, waste of treatment liquid, and poor versatility of the device. For flexible materials such as membrane materials, fiber materials, and sheet rolls, due to their special morphology and characteristics, continuous treatment is required to obtain good coating uniformity and stability. However, the existing process devices are often not universal and difficult to be directly connected in series and used continuously online; in the entire process of chemical plating of membrane materials, fiber materials, and sheet rolls, the use of the treatment liquid tank of the prior art often increases the use of treatment liquid and the discharge of waste liquid, which wastes costs and has a negative impact on the environment. In addition, the liquid in the treatment liquid tank will affect the uniformity and consistency of the material process treatment due to factors such as poor circulation, impurity accumulation, and by-products during the process, resulting in poor process stability of the final product. Therefore, a continuous treatment device for chemical plating process is needed, which takes into account versatility, environmental protection, low cost and continuous treatment functions.
