Exploring the Application of TQC Sheen AB4400 Automatic Coating Machine in the Development of New Energy Coatings
Date: 2025-12-05Read: 6
With the rapid development of new energy technology, from lithium battery separators, functional coating films, to high-performance thin film materials, an increasing number of processes are affectingCoating thickness, uniformity, and repeatabilityPropose strict requirements. The traditional manual coating method often has problems such as unstable operation, large thickness fluctuations, and poor sample consistency. In this context,Automated and controllable coating solutionIt is becoming a key tool for research and quality control.
As the flagship coating equipment of TQC Sheen brand under Industrial Physics,AB4400 Automatic Coating MachineEquipped with a heated perforated vacuum bed, digital temperature control, 0.1-500 mm/s coating speed, and a comprehensive parameter controllable coating mechanism, specially designed for preparing high-quality and reproducible coating samples.
New energy research and development
Why is it needed
AB4400
In the era of rapid evolution of new energy materials and high permeability membrane technology, from lithium battery separators to functional thin film coatings, each coating may affect subsequent performance indicators such as moisture permeability, weather resistance, and adhesion. Therefore, achieving repeatability, quantifiability, and traceability in the coating process has become a key link that must be overcome in research and quality control. And AB4400 can be easily achieved——
Uniform coating enhances data reliability:
With the help of vacuum fixation, controllable trajectory speed, and precise setting of start and end positions, AB4400 achieves uniform thickness throughout the entire coating area, significantly reducing errors caused by human operation.
Heating vacuum bed, suitable for functional membrane materials:
The coating platform of AB4400 can be heated up to ambient temperature+100 ° C (up to 125 ° C),The adsorption pore size is only 1mmSuitable for thermal sensitive substrates or coating processes that require preheating, such as solar films, diaphragm coatings, etc.
Suitable for both high throughput and small batch:
Automated operations not only accelerate sample preparation speed, but also enable formula screening, process validation, and quality control sampling to be completed on a unified device, balancing research and production support.
Laboratory Quality Control Integration:
In the research and development stage, it can be used for process parameter optimization, and in the production or quality control stage, it can also be used as a standardized coating preparation equipment to provide consistent sample substrates for subsequent thickness measurement, moisture permeability, weather resistance testing, etc.
From research and development to quality control
AB4400 full coverage
In coating research and quality control, high standards mean that international standards, industry norms, and internal consistency management must be taken into account. AB4400 can achieve:
Compliant with coating standards such as ASTM D823, ensuring coating effectiveness from the source;
Automatically save coating parameters (speed, start and end positions, temperature, vacuum status) and enable reusable settings, achieving consistent parameters between equipment and batches;
Establish a standardized coating process to build a complete process from sample preparation, quality control sampling, to performance evaluation, seamlessly connecting coating development and quality control.
In this process, the R&D team can focus on material and formula innovation, while the production or QC team can rely on a unified coating platform to ensure sample consistency and reduce the variable of "coating differences".
Model differences and comparisons
AB4400 and
AB4120 / 4220
In order to adapt to different laboratory configurations or coating needs, TQC Sheen automatic coating machine line has other models to choose from. The following is an overview of the main differences:
Based on specific application scenarios (such as new material development vs. standard coating quality control), substrate type, whether heating is required, and budget conditions, you can choose the model that suits you.
Regarding the vacuum testing bench
Integrated guarantee of coating
In the research and development of new energy membrane materials and high moisture permeable coatings, sample preparation often faces several challenges:Difficulty in stable positioning of substrate, thickness fluctuations caused by micro displacement of coating surface, uneven heating of thermosensitive substrate or film during coating process, and defects caused by vibration or shaking during coating processThe perforated vacuum adsorption bed equipped on AB4400 is specifically designed to address these issues.
Stable adsorption, eliminating substrate movement
A vacuum bed can firmly adsorb films, substrates, or coated plates onto the platform, effectively preventing micro displacement of the substrate due to vibration, manual operation, or sliding during the coating process. In this way, the coating roller or scraper maintains consistency between the starting and ending positions, ensuring more controllable and repetitive changes in coating thickness.
Heating and vacuum in one, suitable for functional thin film coating
The vacuum bed not only provides adsorption, but also has a built-in heating pad that can raise the substrate temperature to ambient temperature+100 ° C (up to+125 ° C). For lithium battery separators, functional thin film coatings, solar film encapsulation layers, etc., preheating the substrate or coating in a hot state can often improve adhesion, improve coating quality, and reduce defect rates. At this point, the dual function of heating and vacuum makes AB4400 particularly suitable for the development of new energy coatings.
In addition,AB4400 adsorption pore size is only 1 mm，Will not affect the film due to adsorption, resulting in uneven coating, while ensuringAdsorb smoothly without causing damage to the membrane material.
Improve thickness consistency and optimize subsequent testing processes
After coating is completed, subsequent thickness measurements, moisture or air permeability tests, and thermal cycling tests are all based on sample consistency. The stable adsorption of the vacuum bed, second level positioning, and programmable trajectory control (speed, start stop position) significantly improve the repeatability of sample preparation. In this way, R&D personnel can focus on materials, formulas, and coating structures themselves without worrying about variable interference caused by coating.
In short, the vacuum bed is the cornerstone of the coating and sample preparation process, and AB4400 is the solution that integrates the vacuum bed with automatic trajectory coating, high temperature control, and more.
