It is suitable for manufacturing hot stamping film, laser film, gold and silver paperboard which need coating and laminating.
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 -
Hot melt adhesive coating
The coating device mainly heats and melts the solid type glue, and directly sprays the glue on the substrate through the coating die by hydraulic loading. Hot melt adhesive coating is a new technology developed in the past ten years. Hot melt adhesive coating does not require drying equipment and has low energy consumption. Hot melt adhesive is 100% solid rubber component and does not contain toxic organic solvents. Ordinary sizing coatings use toxic organic solvents (such as benzene) to dilute the glue, and the toxic gases caused by them are extremely harmful to the operator.
Hot melt adhesive coating has its unique advantages over conventional size coating. Hot melt adhesive coating is a green and environmentally friendly coating technology. It has high production speed, high efficiency, low cost, small equipment footprint and short investment recovery period. It is an economical investment project and has been widely used in packaging. , medicine, automotive, clothing, electronics and other industries. Hot melt adhesive coating has great market development prospects, and the development ratio of this technology in the market will become larger and larger, and new application fields will continue to emerge.
Squeegee method and application
In the coating process, the glue is often uneven, which requires a certain scraping mechanism to evenly scrape the glue. The scraping mechanism mainly includes a stainless steel scraper, a comma scraper, a scraping bar, a wire scraper, an air jet scraper, and the like.
