Product Description

Lab Doctor Blade Coater Precision Knife Applicator Adjustable Coating Speed Film Preparation Equipment

The coating testing machine is used for sample testing of coatings, adhesives, hot melt adhesives, conductive materials, nanomaterials, etc., on materials such as paper, non-woven fabrics, glass, copper foil, and aluminum foil.
Since the main factors affecting the coating film are coating speed and the pressure applied to the coating device, manually coated coatings often exhibit inconsistencies, especially between different people, making it difficult to compare test results between samples. This coating testing machine features automatic coating, adjustable coating speed, and quantitatively adjustable coating pressure. This fundamentally solves the shortcomings of manual coating. It can produce wet films with good repeatability and accurate film thickness, thus providing stable coating samples for the measurement and research of various coating properties.

Substrate Support Method and Platform Parameters
Mechanical Clamp
1. Application: Used for supporting substrates with certain stress and low elasticity, such as paper, glass, etc.
2. Material: Stainless Steel
Non-woven Fabric Clamp
1. Application: Used for supporting elastic materials such as textiles; non-woven fabrics can also support paper.
2. Material: Precision-ground and quenched round bar
3. Pressure: Adjustable (Adjust screw tightness)
Vacuum Adsorption
1. Application: Used for holding substrates that cannot flatten themselves and for easy handling of rigid materials such as copper foil, aluminum foil, plastic sheets, and glass.
2. Material: Die steel with quenching treatment + mirror polishing + chemical plating
3. Vacuum adsorption aperture: 0.85mm
4. Number of vacuum adsorption holes: 738
5. Platform flatness: ±2.5 micrometers (effective width within 300mm, effective length within 400mm, heating temperature within 200 degrees Celsius)
6. Vacuum pump: External water-circulating vacuum pump
7. Power supply: 150-220V 50Hz 380W
Magnetic Adhesion
1. Application: For adsorbing magnetically adsorbable metal plates smaller than 3mm.
2. Material: Strong magnetic platform
3. Platform Flatness: ≤3um
Note: The flatness of the plate and the straightness of the squeegee do not represent the wet film coating error, because the viscosity and particle diameter of the paint both affect the coating accuracy during the coating process. At the same time, the improvement of paint flowability and the percentage of wet-to-dry film formation will reduce machine error.
Product Features
1. Uses ball screw drive for better running stability.
2. Digitally adjustable speed, allowing you to select the appropriate speed as needed.
3. Pressure: Employs a weight-based pressure structure for quantified pressure values, facilitating pressure adjustment.
4. The platform undergoes a special process, resulting in superior flatness, more than 10 times higher than glass.
5. Equipped with a vacuum adsorption plate to adsorb substrates with uneven surfaces and certain stress; the external vacuum pump reduces the impact of vacuum vibration on coating.
6. The base plate undergoes a special treatment process to prevent deformation under heat within a certain temperature range, ensuring uniform coating.
Optional Functions and Applications of Coating Testing Machine:
1. Base Plate Heating Function: Used for coating liquids that require fluidity at a specific temperature and need to maintain a consistent temperature throughout the coating process. Applicable Materials: Hot melt adhesives, poultices, etc.
2. Top Heating: Directly dries samples on the machine, and is suitable for coating liquids with low viscosity that are prone to thickness variations during movement. Applicable Materials: Lithium battery electrode coating.
3. Vacuum Adsorption Plate: Used to fix materials with certain stress that cannot be flattened by their own weight. Applicable Materials: Copper foil, aluminum foil, glass plates, and thicker plastic sheets.
Selection of Coating Rods and Doctor Blades
1. For coating tests with high viscosity and high coating thickness, four-sided doctor blades or adjustable doctor blades are generally used.
2. For coating tests with low viscosity and thin coating thickness, rod coating is generally used.
