Characteristics of several coating methods -

1. Characteristics of air knife coating process:
The advantage of air knife coating is that a thick coating amount can be obtained, the coating layer is relatively uniform, and paper breakage is less likely to occur during coating. The disadvantage is that since the coater of the coater is an invisible air knife, it is necessary to require the paint to be soft and easy to control in order to scrape off excess paint and smooth the coating. In addition, the air knife formed by the air jet is more likely to cause the splash phenomenon of the paint, and the splash of the paint easily causes partial clogging of the air knife gap, resulting in unevenness of the coating layer.

Scraper coating:
advantage:
1. Can make the paper get higher smoothness and gloss
2. The operability is higher than the air knife and the measuring rod, and the adjustment precision is higher than the latter two.
Disadvantages:
1. High requirements for base paper (to have good flatness, smoothness, sizing degree, etc.)
2. If it is used for topcoating, it also has higher requirements for lining (lower macroscopic roughness, but with appropriate micro-roughness)
3. This performance is good without air knives and measuring rods.
4. Easy to scratch the knife.

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.
