The film coating machine can play an important role in the preparation process of the fingerprint film, and can achieve high-precision, effective and repeatable coating operations. The coating application of fingerprint film and its film-making method are introduced below.
Fingerprint film is a film with special functions. It has the characteristics of anti-fingerprint and anti-scratch. It is widely used in display screens and touch screens of electronic devices such as smart phones, tablet computers, and laptops. The coating film preparation of the fingerprint film refers to coating a thin film with special functions on the surface of the substrate.
Membrane method
The film-making methods of fingerprint film mainly include solution method, vapor deposition method, hot pressing method, electroplating method and other methods, among which solution method is a relatively common method. In the process of preparing fingerprint film, a coating machine is required for coating operation. This machine can control parameters such as coating thickness, speed, and time according to different needs, so as to ensure the stability and accuracy of the coating process.
Coating steps
During the coating process, it is first necessary to pour the solution to be coated into the coating tank of the coating machine, and then fix the substrate on the coating table of the coating machine. Next, start the coating machine, and control the motion trajectory and speed of the coating knife so that the coating knife can evenly coat the solution on the surface of the substrate. After the coating is completed, the substrate is taken out and subjected to subsequent processing steps under appropriate conditions, such as drying, curing, etc.
NBCHAO reminds you: during the coating process, the accuracy of the coating thickness needs to be controlled to ensure that the prepared fingerprint film has better performance. The coater knives should be kept clean to avoid contamination of the solution and substrate surface.
To sum up, the film coating machine plays an important role in the preparation process of the fingerprint film, and can achieve high-precision, effective and repeatable coating operations. The prepared fingerprint film has good performance and stability, and is widely used in fields such as display screens and touch screens of electronic equipment.
