1. 150m/min high speed has already reached the international most advanced level.
2. Rewind and unwind both adopt double position and equip with semi-automatic to connect paper device, The machine can change the rolls of base material nonstop， It will reduce the waste.
3. When the double sides adhesive tape coat twice, it will effect the quality of products, but the technology of double sides coating meanwhile will solve the questions.
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!
Development of coating technology
From the analysis of the development situation in recent years, the future development of coating technology may present the following three important characteristics:
l Scraper coating will remain the most important coating method for a period of time in the future, and is developing towards high speed and high solid content;
l The measurement method of measuring size and pressure is widely accepted and developed rapidly;
l New coating methods such as spray coating and curtain coating have received widespread attention, indicating a bright future;
However, the above developments are unlikely to be smooth and must face many technical challenges. High-solid-state blade coating can cause running problems such as scraper marks, large blade pressure, paint deposition on the blade (commonly known as turning) and blade wear. Metering size press coating must face high speed and high solidity. The problems caused by the coating of high content and high coating amount. It includes fog splashing at the exit of the coating roll nip, orange peel paper on the coated surface, etc.; the new coating method also solves the new problems that have not been encountered in conventional coating.
