Wet film preparers can be divided into different types according to different dimensions. From the style, they can be divided into I-shaped, frame, and square; from the thickness of the coating film, they can be divided into single-sided, two-sided, four-sided and adjustable. According to the sales experience of wet film generators, NBCHAO has also sorted out professional selection models.
Among them, the I-shaped and the frame type are four-sided coating film preparers, which can scrape and coat four different wet film thicknesses on four sides. The appearance of the I-shaped Wet Film Applicator is a columnar shape, while the frame type Applicator is a hollowed-out cuboid in the middle. Both have the same coating effect, so users often have doubts when choosing this Wet Film Applicator, what is the difference between the two, especially how to scrape during operation? The professional and technical engineers of the northern and southern tides use a picture to explain and illustrate the two in a simple and clear way.
It can be seen from the figure that the ink of the frame Applicator is placed inside the frame. There are certain grooves on the four sides of the frame Applicator, and there is a gap between them and the plane support points. As shown above. The red point is the support point of the plane, and the difference between the green point and the red point is 120 μm; the difference between the blue point and the red point is 60 μm. So when the yellow ink is placed inside the frame, if the ink is scraped against the green side, the thickness is 120 μm, and if the ink is scraped against the blue side, then the thickness is 60 μm. The same principle applies to the two sides on the other side.
Furthermore, for the I-shaped Wet Film Applicator, there is also a difference between different surfaces and the flat support surface, so different wet film thicknesses are produced by scraping on different surfaces. The difference is that the I-shaped wet Film Applicator puts the ink in front of the direction to be scraped, not inside.
In fact, the two can be used interchangeably, that is, the position of the ink for scraping is different.
Understand the difference between the two operations. Let's take a look at the detailed pictures of the I-shaped Wet Film Applicator and the style Applicator taken by NBCHAO for appreciation.
NBCHAO has gathered more than a dozen imported and domestic brands of Wet Film Applicators, which can be selected from the middle, high-low end. For details, please enter: https://www.nbchao.com/list20/
