Four-sided wet film preparer is a manual film proofing used for coatings, inks, paints and other experiments, and can also be placed on the automatic coating machine to make films, with four coating film thicknesses,SZQ-290 15/25/35/45It is made of high-quality wear-resistant and corrosion-resistant alloy steel, and the coating film thickness is15、25、35、45μm, coating width 300mm。
The applicator provides precise control of the thickness of wet or dry films. In routine quality control and research and development tests, the coating's covering power, opacity, scrubbing resistance, sagging resistance and other quality tests require a coating with good consistency and repeatability.
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
