Second, the length of the coating section changes, the spacing is unstable:

3. Reasons and countermeasures for the phenomenon of wrinkling of the pole piece during the operation of the coater
1. The overall installation accuracy is low. The installation center of each component deviates from the center line of the whole machine design, or it has an angle with the design center. The foil strip will be seriously wrinkled and the installation center must be adjusted.
2. The excessive parallelism between the rollers will cause the foil strip to wrinkle. It is necessary to check carefully whether the vertical projection surfaces are not parallel or the horizontal plane is not parallel, and then adjust.
3. The roughness of the surface of the roller is too poor, the surface of the roller is not smooth enough, and the foil is wrinkled when there is obvious processing texture. It needs to be replaced by the manufacturer.
4. The back roller and each roller are stuck with foreign matter or use too much water. Isopropyl alcohol scrubbing requires frequent inspection, timely detection and cleaning, and careful not to damage the roller surface.
5. The foil strip joint is not good. When the tension between the two sides of the foil strip is unbalanced, the pole piece is wrinkled. First adjust the tension adjusting roller under the coating head. After the foil strip is gradually stable, adjust the adjusting roller to the original state.

PET film--

 

(2) PET transfer film
The transfer film is also called a heat transfer film. The transfer film is characterized by high tensile strength, good thermal stability, low heat shrinkage, smooth surface and good peelability, and can be used repeatedly. It is mainly used as a vacuum aluminum plating carrier. After the PET film is placed in a vacuum aluminum plating machine, the rubber film is combined with the paper, and then the PET film is peeled off, and the aluminum molecular layer is transferred to the surface of the paperboard by the adhesive action. A so-called aluminized cardboard is formed. The production process of aluminized cardboard is:
PET base film→release layer→color layer→aluminized layer→glue layer→transfer to cardboard.
Vacuum aluminum-plated cardboard is a kind of high-grade novel packaging material developed with metal-gloss cardboard. This kind of aluminum-plated cardboard has bright color, strong metallic feeling, bright and elegant printing, and can replace the large-area bronzing of printed matter, which has played a icing on the cake for the beautification of goods. Because it adopts the vacuum aluminum plating method, the surface of the cardboard is covered with only a thin layer of 0.25um~0.3um thin and bright and bright, only one-fifth of the aluminum foil layer of the aluminum foil, so that it It has a noble and beautiful metallic texture, and has environmentally friendly properties that are degradable and recyclable. It is a green packaging material. Through the formulation and process adjustment, Jiangsu Zhongda was successfully developed in 2005 and put into the market in large quantities, receiving good economic benefits.
