foreword
With GJ's emphasis on environmental protection development, after all, there will be corresponding derivatives to help environmental protection. Water-based film is naturally a product that should not be underestimated. Water-based film is a water-based environmental protection film. The more common application is water-soluble film, which is similar to water-soluble environmental protection bags. In fact, the material is also a water-based film. White pollution from ordinary plastic bags. In the application case of film coating machine in this issue, Beichao Technology recommends a wire rod scraper type heating film coating machine for preparing water-based films on glass substrates.
User needs
The needs of users are divided into two points:
1. The viscosity of the water-based film sample is not high, and it needs to be heated when it is coated with more than ten microns.
2. The width can be adjusted to be coated on the glass substrate, and the film needs to be peeled off
Selection Analysis
| Substrate | Glass | sample | water-based paint |
| film thickness | Tens of microns | other requirements | heating, adjustable width |
This experiment is actually a relatively common application of film coating. NBCHAO's film coating machine has designed a high-precision Film Applicator to make the film coating effect more precise. For samples whose viscosity is not very high and the thickness of the coating film is only more than ten microns, the wire rod for coating equipment is the best, and the precision is higher than that of a scraper. 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.
