Wire Rod | 1.Coating Solution Volume Control The rod controls the amount of coating solution per unit area by contacting the substrate surface. The surface of the rod typically has fine grooves or stripes, which help adjust the coating thickness through contact with the coating solution. By adjusting the contact pressure and speed between the rod and the substrate, the volume of the coating solution can be precisely controlled. 2.Coating Thickness Control The height or geometry of the rod determines the thickness of the coating layer. Depending on the requirements, the coating thickness can be controlled by selecting different rods or adjusting the rod settings. The thickness of the coating layer after application can range from a few microns to several hundred microns, catering to different application needs. |
Vacuum pump | 1.Substrate Fixation: In some coating machines (such as roll coaters, spray coaters, spin coaters, etc.), vacuum adsorption helps fix the substrate (e.g., film or paper) onto the worktable, preventing the substrate from moving or deforming during the coating process. Vacuum adsorption ensures that the substrate remains securely in place within the coating machine’s work area, ensuring the precision and consistency of the coating process. 2.Preventing Substrate Warping or Floating: For flexible materials, vacuum adsorption can prevent the material from warping or floating due to air currents or other forces during the coating process. This is especially important for materials like films and papers, helping to ensure that the coating is applied evenly and smoothly. 3.Improving Coating Precision: By ensuring that the substrate remains fixed in place during the coating process, vacuum adsorption improves the coating precision, reducing substrate displacement or tilting. This helps ensure the uniformity and quality of the coating. 4.Stability During the Coating Process: Vacuum adsorption helps maintain stable contact between the substrate and the coating head or nozzle throughout the entire coating process, reducing issues caused by substrate movement, such as uneven coatings or incomplete coating application. |

The bar coater is a device commonly used in coating technology, especially for applications with precise control of coating thickness. For the coating of pressure-sensitive adhesive (PSA), the bar coater can achieve uniform coating and ensure the consistency and stability of the adhesive layer. The following are the basic steps for preparing pressure-sensitive adhesive by bar coater:
1. Prepare the pressure-sensitive adhesive solution
Material selection: Select a suitable pressure-sensitive adhesive formula according to needs. Pressure-sensitive adhesives are usually composed of polymers (such as acrylic acid, rubber, acrylate, silicone, etc.), tackifiers, solvents (such as water or organic solvents), thickeners, etc.
Dissolution and preparation: Mix the selected pressure-sensitive adhesive raw materials and solvents in proportion, stir and dissolve until a uniform coating solution is formed.
Viscosity adjustment: Adjust the viscosity of the coating solution as needed to ensure that it is suitable for coating by the bar coater.
2. Preparation and heating of coating solution
Solvent removal: If the pressure-sensitive adhesive formula contains solvent, the coating solution usually needs to be heated or vacuumed to remove excess solvent to ensure the stability of the coating solution.
Heating system: The temperature of the coating liquid is adjusted through the coating machine's heating system to ensure that it is coated within the appropriate viscosity range.
3. Adjust the distance between the wire rod and the substrate
Select the wire rod model: According to the viscosity of the pressure-sensitive adhesive and the coating thickness requirements, select the appropriate wire rod type and size. The groove depth and surface morphology of the wire rod will affect the coating thickness.
Set the distance between the wire rod and the substrate: Adjust the gap between the wire rod and the substrate to ensure that the coating liquid can be evenly coated on the substrate surface. Too large a gap will result in too thick a coating, while too small a gap may result in uneven coating.
4. Coating process
Substrate preparation: The substrate (such as paper, film, plastic, metal foil, etc.) usually requires surface treatment, such as cleaning or pretreatment, to enhance the adhesion of the pressure-sensitive adhesive.
Coating operation: Start the wire rod coater and evenly coat the prepared pressure-sensitive adhesive liquid on the substrate surface. The wire rod controls the thickness of the coating liquid by contacting the substrate surface.
Coating speed: Adjust the coating speed to ensure uniform coating and avoid bubbles, brush marks or drawing.
5. Drying and curing
Drying (solvent evaporation): After coating, the substrate needs to be dried in an oven or hot air drying system to remove excess solvent, usually at a lower temperature.
Curing: Some pressure-sensitive adhesives require further curing, using ultraviolet (UV) curing, thermal curing and other methods to improve their bonding strength and performance. At this time, the coating layer needs to be cured by appropriate oven or UV lamp irradiation.
Temperature control: Temperature control is very important during drying and curing. Too high temperature may affect the performance of the pressure-sensitive adhesive, and too low temperature may result in incomplete curing.
6. Cooling and cutting
Cooling: The coated substrate usually needs to be cooled naturally or cooled by a cooling system to maintain the stability of the coating.
Cutting and winding: If the coated material needs to be stored or transported in roll form, the coated substrate can be handled by a cutting and winding system. The pressure-sensitive adhesive film can be slit or cut to the required width or length.
7. Inspection and quality control
Thickness detection: Use a coating thickness instrument to measure the thickness of the coating layer to ensure that it meets the requirements.
Adhesion test: Perform adhesion test on the pressure-sensitive adhesive to ensure that its bonding performance on different substrates meets the standards.
Appearance inspection: Check whether the coating surface is smooth and uniform, and whether there are defects such as bubbles and scratches.
8. Storage and packaging
Packaging: Qualified pressure-sensitive adhesive coated substrates can be packaged to prevent them from being contaminated or damaged. The packaging method is usually coil or sheet packaging, which is suitable for subsequent applications.
Storage: The storage environment should be kept dry, clean and at a stable temperature to avoid the influence of high temperature or humidity on the performance of the pressure-sensitive adhesive.
