Slit blade coater is a laboratory coating equipment, often used to apply a thin film coating on the surface of the substrate. During the coating process, the paint or adhesive is passed through a slit and then evenly scraped off by a scraper, so that the paint forms a uniform film on the substrate. The coating machine can accurately control the coating thickness and is suitable for the preparation and research of various film materials. Slit scraper coater is widely used in printing, packaging, painting and other fields for uniform coating of various liquid materials, with slit scraper structure to control coating thickness. Selection points include coating speed, material compatibility, uniformity, control accuracy, cleaning and maintenance, and production capacity to meet the needs of different processes.

Comma scrapers are often made of round steel with good strength and hardness. The scraper is fixed and does not rotate when scraping. The strength and hardness of the scraper are high, the straightness error of the cutting edge is small, and the position of the scraper can be adjusted and controlled by pneumatic and fine-tuning mechanism, and the coating amount control and scraping accuracy are high, and the use is also extremely convenient. Because of its uniform scraping, it is suitable for precise scraping on smooth roller coating. This coating method is widely used in a variety of coating lines, which is characterized by high coating accuracy, large adjustable range of coating thickness, good adaptability to glue viscosity and solid content, simple structure and simple operation.
