1.Special materials are used to control the swelling of proton membrane, with strong anti swelling ability, and the dry thickness range of coating is 2~20 μ m       

2.High machining accuracy of backing roll with a circular runout ≤ 1.5 μ m

3.The coated area rarely contacts the roller, reducing the risk of contamination

4.Optimize the production process, and anode coating is possible without additional process film, saving production and manufacturing costs

1.Special Reversing valve design, optimized head and tail influence area ≤ 5mm

2.The coated area rarely contacts the roller, reducing the risk of contamination

3.High machining accuracy of backing roll, circular runout ≤ 1.5 μ m

4.High oven temperature uniformity ≤± 2 ℃
