Characteristics of several coating methods -

Coating technology
Coating technology is widely used in the coating and composite packaging of substrates such as paper and film. At present, many domestic printing and packaging machinery enterprises use coating composite equipment, and their coating types and scraping methods are relatively simple, and the application of coating technology is also greatly limited. Regardless of the coating composite equipment, the key part is the coating head, and the coating method of the coating head directly affects the quality and effect of the coating.

Glue coating type and application
Coating compound equipment is mainly used for sizing coating and composite processing of various reel substrates such as plastic film, paper, electrochemical aluminum, cloth and leather. It is widely used in various packaging fields and has broad development prospects. The coating composite equipment is roughly coated with a splitting roller, an anilox coating, and a hot melt adhesive.

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.
