实验刮棒

The experimental drawdown rod is used to apply a uniform wet film on a substrate surface by evenly scraping with a metal rod, primarily for testing the coating thickness of paints and inks. Its principle relies on controlling the coating thickness through the gap between the rod and the substrate, making it suitable for simulating coating processes and quality control in laboratory settings.
Selection
When selecting, consider the rod diameter in relation to the coating thickness, the corrosion resistance of the stainless steel material, the rod length matching the substrate width, and the surface smoothness affecting the coating uniformity. Choose the appropriate groove type based on the viscosity of the material being tested to ensure consistency with actual production conditions.
