The heating type flat coating machine is mainly used to uniformly coat materials on the surface of substrates and improve coating performance through heating. It is suitable for fields such as semiconductor materials, electronic components, optical films, etc.
The working principle of the heating type flat coating machine is mainly based on hot pressing composite technology. The coating material is uniformly applied to the surface of the substrate through hot pressing rollers or hot pressing plates, and the adhesive is activated or the coating adhesion is improved by heating.
The heating type flat coating machine has added a temperature control module to the ordinary coating machine, and its main advantages are reflected in the following three points:
Accurate temperature control improves coating quality: The flat base can achieve accurate temperature control from room temperature to 300 ℃ (higher for some high-temperature models), avoiding the occurrence of bubbles, sagging or uneven curing of coating materials due to temperature fluctuations, especially suitable for temperature sensitive coating processes (such as photoresist, conductive paste).
Accelerating curing and shortening production cycle: The heating function can directly act on the coated substrate, accelerating the curing reaction of coating materials (such as resins and adhesives). Compared with natural curing or external ovens, it can save more than 50% of waiting time and improve production efficiency.
Enhance coating adhesion: By heating, the microstructure of the substrate surface is more easily combined with the coating material, reducing interface voids and significantly improving the wear resistance, scratch resistance, and peel resistance of the coating. It is suitable for scenarios with high adhesion requirements such as electronic component protection and battery electrode coating.
Technical Features
Heating and drying system
Bottom heating: Heating the coating directly through a heating plate, with a temperature range usually from room temperature to 150 ℃ and uniformity of ± 3 ℃, can quickly dry the slurry and avoid leveling defects.
Platform heating: Suitable for rigid substrates (such as glass), with a temperature of up to 200 ℃, meeting high-temperature coating requirements.
Infrared heating: using infrared lamps to synchronously heat the coating, with high drying efficiency and good apparent quality.
Diversity of coating processes
Supports various processes such as scraper coating, wire rod coating, slit extrusion coating, and four sided film maker coating, and is compatible with materials of different viscosities (such as lithium-ion battery slurry, ceramic slurry, adhesives, etc.).
The coating thickness accuracy reaches ± 2 μ m, and the adjustable range of the scraper is 0.01-3.5mm, meeting the requirements of film preparation.
Automation and Intelligence
Digital display temperature controller, with an accuracy of ± 1 ℃, can freely set the drying time and temperature curve.
The travel switch supports 10-250mm travel adjustment, and the coating speed can be adjusted from 0-120mm/second to adapt to different sizes of substrates.
Vacuum aluminum disc design, quickly adsorbs substrate to prevent displacement during coating process.
Safety and Environmental Protection
The enclosed heating chamber prevents solvent evaporation and diffusion, and is equipped with an activated carbon filtration system to absorb organic volatiles.
The emergency stop switch and temperature over limit alarm function ensure safe operation.
