Wet film preparer is a kind of manual film coating equipment, made of high carbon chromium wear-resistant and anti-corrosion stainless steel, there are I-shaped, frame, square and other shapes, wet film preparer can be divided into single-sided, double-sided, four-sided, eight-sided different preparers according to the thickness of the coating film. The wet film preparer is suitable for scraping high viscosity and high film thickness of coatings, inks, glues, new materials and other samples, and can also be used with the coating machine for automatic coating of films. Support different specifications customization, and each preparer adopts imported three-coordinate testing to ensure the accuracy of the experimental coating film.
SZQ-150 (150mm) single-sided coating applicator has a coating thickness of 150μm, single-sided coating, a coating width of 150mm, and a coating accuracy of ±2μm.
1. 9Cr18Mo high-hardness stainless steel, with good wear resistance and corrosion resistance, hardness value up to 50~55HRC.
2. The accuracy is up to ±2μm to ensure the accuracy of the experiment
3. The surface is smooth, the style is diverse, the application range is wide, and customized specifications are supported
4. Adopt imported three-coordinate testing accuracy, bring factory test report, and stand up to measurement
