Fives. Summary summary
Since the beginning and the end, all kinds of civilian tapes, industrial tapes and traditional medical tapes from ancient and modern Chinese and foreign countries have emerged on the basis of technical transformation of adhesives and media. Their products have also experienced intermittent fluctuations of thousands of years. Among them, black tape electrical insulating tape and wet water kraft paper tape, which is the most typical representative product of Xingsheng defeat, but it still exists in the tape market today, which proves that the social and economic benefits of tape products can not be ignored. As for the rise and fall of individual products, it is only possible to change and grow at a high speed according to changes in the times, changes in living environment conditions, or adjustment or improvement of industrial automation production structures. However, the fact is that tape products have developed with the development of human civilization and attached to the consumption index of social life, and have developed at a high speed. It has been subtly deepened in social
In the trend of economic growth and technological development, the flow has been long-lasting!
Characteristics of several coating methods -
This size coating is typically applied by two roll transfer. By adjusting the gap between the upper rubber roller and the coating roller, the amount of coating can be adjusted. The structure of the entire coating head portion is relatively complicated, and the processing precision and assembly precision of the rubber roller, the coating roller, the traction roller and the scraper are required, and the cost is relatively high. Since the coating machine mainly uses a high-precision optical roller for sizing coating, the coating effect is good, and the coating amount is adjusted by the gap between the sizing roller and the coating roller, and can also be coated. The micro-motion adjustment of the scraper is flexibly controlled, and the coating precision is high. It is currently the most widely used on coated composite equipment.
This coating apparatus mainly uses a textured (concave-eye) coating roll for sizing coating. The coating is uniform and the coating amount is relatively accurate (but the coating amount is difficult to adjust). When coated with an anilox roll, the amount of coating is mainly related to the depth of the concave surface of the anilox roll and the accuracy of the type of glue. The deeper the depth of the concave surface of the anilox roll, the greater the amount of glue transferred from the concave eye to the substrate; conversely, the shallower the depth of the concave surface of the anilox roll, the amount of transfer to the substrate is correspondingly reduced. It also has a lot to do with viscosity. Too much viscosity and too small a glue is not conducive to the normal transfer of glue. Glue viscosity is easy to transfer, too thin is easy to flow, so that the glue is not uniform, easy to produce vertical or horizontal flow pattern. Therefore, once the type of the coated anilox roll and the glue are fixed, it is difficult to adjust the coating amount, which is also the main reason for the limitation of the application of the textured coating roller.
