Case study | Automatic film coating machine for scraping emulsion on polyimide

There are two key points in the selection of the automatic film coating machine, one is the nature of the substrate and the sample, and the other is the thickness of the coating film. In addition, consider other functional requirements. Polyimide is a polymer material with high heat resistance. It is used as a substrate to make a scraping film. Simply speaking, it is actually an emulsion coating on a polymer film.

As a film substrate, there is no doubt that the vacuum adsorption function is required, unless it is a very hard film, but polyimide is generally a relatively flexible film substrate, so it must be equipped with a vacuum adsorption function. In addition, SEP emulsion is a sample with low viscosity, so it can be scraped with a wire stick and a scraper. In fact, due to the various thicknesses of the scraping coating, it can be equipped with a wire rod + scraper integrated film coating machine model. Of course, the NBCHAO film coating machine can also be equipped with a manual scraping coating Applicator, which is not necessarily an integrated one.

In addition, in the coating experiment of polymer materials, it is often necessary to dry and cure the film after scraping the film. Generally, there are two options, one is to put the film on the oven for drying, and the other is to dry the film through the coating. The built-in heating and drying function of the machine can cure quickly.

To sum up the above case analysis, the four-in-one automatic film coating machine is an optimal solution for the type selection requirements of the coating film, which can meet the various needs of high-low film thickness. In addition, a three-in-one coating Tester with wire rod + heating + vacuum adsorption function can also be used, which is suitable for low-viscosity coating films. The detailed plan is as follows:
