Paper Core Loading Machine

Characteristics of several coating methods -

Air knife coating:
advantage:
1. Because it is a profile coating, it can provide better shielding performance than any known coating machine.
2. There is no mechanical contact in the metering method, and it will not cause scraping marks.
Disadvantages:
1. The solid content of the air knife coating coating formulation can not be made too high up to 48%, too high solid content will lead to too high viscosity of the coating will make the coating amount difficult to control.
2. Low solids content of the coating will cost a lot of drying costs
3. The low solid content of the coating results in poor water retention, and the coating shrinks severely during the drying stage, ultimately affecting the roughness of the coating.
4. Significant loss of paint, high water consumption, and high environmental pressure.

Metering bar coating:
Advantages:
1. Low requirements for base paper, can adapt to rougher base paper
2. Can adapt to high solid content coating
3. Better shielding
Disadvantages:
1. The adjustable amount of coating is worse than the scraper, and the typical value is 7-11 grams.
2. If you use a grooved stick, you will leave a lot of sticks.
3. When the required coating amount is relatively low, the metering rod is easily worn.

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.
