Common coater blades include ceramic blade, steel blade, alloy blade, etc

 

Coating machine ceramic scraper:
Relatively ideal at low speed
The service life is relatively short at high speed
The controllability is worse than alloy scraper
CD banner control can not reach the ideal state easily

Coating machine steel scraper:
The original angle of the scraper is difficult to maintain for a long time
It is relatively difficult to control the coating amount
It is difficult to guarantee the quality of coating

Coating machine alloy scraper:
It is a widely used scraper at present
It can be used in low, medium and high speed.
Wear resistance, good elasticity and high hardness.
It can improve the quality of paper products
Relatively speaking, the service life is longer and the production capacity is improved
It has better printing performance and saves cost
Strong operability (normative operation is very important)
