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

6. When the back roller and the coating roller are in contact with each other, the gap between the two ends is inconsistent and the pole piece is wrinkled. Regardless of whether the first side or the second side is applied, the gap should be carefully adjusted. First, the gap is appropriately enlarged, and then slowly reduced. At the same time, observe the dial scale of the coating roller just touching the foil strip, and then Reduce the gap by 0.03mm.
7. When the correction system is abnormal, the pole piece will be wrinkled. Check the three correction systems before and after the inspection, whether it is in the automatic state. If the lengths of the foil strips are inconsistent, that is, when the file is bent too much, the pole pieces will be wrinkled. Exceeding the correcting ability, the foil has to be replaced. 8. When the pole piece tension is too large, the pole piece is wrinkled. Check that the tension setting is reasonable. Then check each drive roller. The rotation of the take-up roll is flexible. Handle inflexible rollers in time.
9. When the back roller is in the inconsistent stroke, the pole piece is wrinkled. It is necessary for the mechanic to check. Confirm and adjust. After the back roller and the coating roller are pulled apart, the gap between the two sides is 1mm (see the dial indicator), and the test is started. When the tail is qualified, lock the nut.

10. The surface of the rubber roller on the back roller will undergo periodic elastic deformation during re-use. When a certain degree of deformation remains, wrinkles will occur. At this time, new products must be replaced.
11. The cause of looseness of a certain roller fastening screw causes the parallel state of each roller to be destroyed, and wrinkles may occur at this time. As long as it is found in time to adjust and tighten in time.

PET film--


(3) PET reflective film
PET reflective film is characterized by excellent optical properties, smooth surface, smooth surface, good thermal stability, low shrinkage and light aging resistance.
Reflective materials used in transportation facilities include lens-type retroreflective film and flat-top reflective film. They are all made of aluminized PET film as a reflective layer. After applying pressure sensitive adhesive, some glasses with a refractive index of 1.9 are used. The beads are adhered to the PET aluminized film, and then a layer of butyral surface protective layer is sprayed.
PET reflective film is applied to billboards with reflective requirements, traffic reflective signs (reflective road signs, reflective barriers, reflective number plates), reflective police uniforms, industrial safety signs, etc.

(4) Chemical coating film
Polyester film In order to improve the surface properties of the PET film, in order to improve the adaptability of printing and the bonding force of the vacuum aluminum plating layer, a corona treatment method is generally used to increase the surface tension of the film. However, the corona method has problems such as aging, and particularly in a high-temperature, high-humidity environment, the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing industry and the aluminum plating industry. Jiangsu Zhongda has developed a series of PET chemical coating products: coating with water-soluble polymer can improve the surface tension of PET film; coating with acrylate emulsion can improve printing adaptability (water-soluble ink can be used) The coating with polyurethane aqueous solution can strengthen the bonding force between the aluminum plating layer and the PET base film, and can increase the thickness of the aluminum plating layer.
In addition, a high-resistance film, an antistatic film, and the like can be obtained by a coating method.
