What are the types and features of coaters?

   Coating operations according to the relationship between the coater and the paper machine is divided into in-machine and out-of-machine, according to the number of coats is divided into single-layer coating and double-layer coating. In-machine coating is equipped with a coating machine in the paper machine, so that paper and coating continuous stop; outside the machine coating is coated with the paper machine and their respective independent, for coating operations of the coating machine mainly roller coating machine, air knife coating machine and scraper coating machine three.

   Roll coating machine is a coating roller to the paper surface with coating, in-machine coating to this type of coating machine. The amount of coating can be measured by the pressure between the rollers to stop regulating the pressure to enhance the amount of paint through the reduction in the amount of coating is also reduced.

   Roller double-sided coating machine has the advantage of simple structure, can stop both sides of the coating, as the machine coating machine and has a more suitable coating speed, and is not easy to produce coating streaks. Defect is not easy to get the air knife coating machine coating thickness, also can not get the scraper coating machine as smoothness and gloss.
