Barrier film primer after UV bonding coating solution [Coating machine case]

foreword

The primer coating of the barrier film and then the UV adhesive coating film experiment is mainly used to prepare and research high-performance protective isolation films, such as display screen protection, UV ultraviolet isolation protective glasses film, gas isolation protection, and other isolation packaging protective films, etc. At present, this kind of research is still relatively extensive. According to the specific experimental needs, NBCHAO Technology recommends a wire rod scraper heating coating machine solution.

User needs

The needs of users are divided into two points:

1. Barrier film primer coating coating, to meet the dry thickness of 1um uniform coating.

2. The thickness of the scraper can be adjusted to carry out UV glue bonding, and the coating width is 300mm.

Selection Analysis

From the point of view of the user’s experimental needs, firstly, the barrier film needs to be scraped and coated with a layer of dry film thickness of 1 μm. On the one hand, the imported wire rod is more accurate for the film preparation below 10 μm. On the other hand, the barrier film As a soft substrate, the ordinary film coating machine cannot be fixed well, and the vacuum adsorption function is needed to maintain its stable flatness; moreover, after scraping the primer coating, it needs to be pasted with UV glue, as the glue , It needs to be kept in a molten state at a certain temperature, so it needs to be equipped with a heating function, and the UV adhesive has a high viscosity and an uncertain film thickness. It can be equipped with an adjustable scraper Applicator to freely adjust the film thickness. Therefore, Beichao Technology recommends wire rod + scraper + heating three-in-one functional coating machine.

Instrument parameters

Let's take a look at the specific parameters of the film coating machine for reference by industry users. Other specifications can be customized.
