Ultrasonic Spray Coating Machine for Polishing Resin

Ultrasonic Spray Coating Machine for Polishing Resin -Cheersonic

In the current era of rapid upgrading in industries such as semiconductor manufacturing, ultrapure water preparation, precision electronic processing, and photovoltaic new energy, polishing resin, as a core functional material, has become crucial for the final fine treatment of ultrapure water systems due to its advantages of high purity, strong adsorption, and easy filling. It is also widely used in precision device surface polishing and resin mold preparation, serving as a core support for ensuring product quality. Polishing resin is typically composed of a mixture of hydrogen-form strong acidic cation exchange resin and hydroxide-form strong basic anion exchange resin. It is shipped in H and OH form and can be used directly after filling without regeneration. It can achieve a high resistivity of over 18 megohms and has excellent control over TOC and SiO₂. Its performance is deeply tied to the uniformity of spraying and the stability of adhesion. Cheersonic ultrasonic spray coating machines, with their core advantages of high precision, low pollution, and high adaptability, perfectly meet the precision spraying needs of polishing resin, solving the pain points of traditional processes and providing core equipment support for its large-scale, high-quality mass production, thus helping related industries improve quality and efficiency.

The high purity requirements and diverse applications of polishing resins impose extremely stringent standards on the spraying process, directly determining its subsequent performance and lifespan. The core spraying process for polishing resin includes coating the resin surface protective layer, modifying the functional layer, and pre-treatment spraying of the resin bed. The coating thickness needs to be precisely controlled within 0.05-0.6μm. The core spraying requirements focus on three main aspects: First, high uniformity coating, requiring precise control of coating thickness and distribution with a deviation of ≤±0.02μm and uniformity of over 99%. Defects such as pinholes, bubbles, and particle agglomeration must be avoided to ensure a dense, void-free coating, guaranteeing the adsorption performance and resistivity stability of the polishing resin and meeting the stringent requirements for ultrapure water preparation. Second, low contamination compatibility, as polishing resin is extremely sensitive to impurities. The spraying process must be completely free of impurities, meeting Class 100 cleanroom standards. Simultaneously, the spraying slurry must be compatible with the characteristics of the polishing resin to avoid chemical reactions affecting its adsorption efficiency. Furthermore, the spraying process must be free of high-pressure impact to prevent resin particle damage. Third, high compatibility, requiring compatibility with different types of polishing resins (such as AMBERJET UP6150, Tulsion). (MB115, etc.), compatible with various spraying carriers such as resin beds and precision components, achieving seamless coating and meeting the needs of multiple scenarios such as semiconductor ultrapure water preparation and precision polishing.

Currently, in the field of polishing resin spraying, traditional spraying processes (high-pressure gas atomization spraying, manual coating, and roller coating) have many shortcomings, making it difficult to adapt to the high-purity and high-precision spraying requirements, becoming a bottleneck restricting the industry’s quality improvement and efficiency enhancement. High-pressure gas atomization spraying easily introduces impurities and moisture, leading to polishing resin contamination and stratification. High-pressure airflow can also cause resin particle breakage, reducing its adsorption performance, with a material utilization rate of only 25%-35%, failing to meet the high purity requirements of ultrapure water preparation. Manual coating is inefficient, with poor coating uniformity. Manual operation easily introduces grease and impurities, contaminating the polishing resin, and is difficult to achieve large-scale mass production. Roller coating, with its contact and friction with the resin, easily generates resin powder, causing secondary contamination, and the coating is uneven, making it unsuitable for seamless coating of complex carriers such as resin beds and precision components, exhibiting poor adaptability.

Cheersonic ultrasonic spraying machines address the characteristics and spraying challenges of polishing resins. Leveraging high-frequency ultrasonic atomization technology, and combining key aspects of polishing resin preparation and application processes, they create customized solutions, completely breaking through traditional process bottlenecks. The equipment converts industrial frequency electricity into a 40-150kHz high-frequency electrical signal via an ultrasonic generator. This signal is then converted into high-frequency mechanical vibration by a piezoelectric ceramic transducer. Utilizing the ultrasonic cavitation effect, protective and functional slurries compatible with polishing resins are atomized into fine droplets of 0.01-2 microns. This effectively deagglomerates particle clusters in the slurry, precisely controls the solvent evaporation rate, and ensures a uniform, fine, dense, and void-free coating. This perfectly meets the core requirements of high purity and strong adsorption of polishing resins, helping to extend their service life and performance. The atomization process is low-pressure, temperature-controlled, and introduces no impurities. Droplets are gently deposited on the surface and gaps of the polishing resin only with the guidance of a small amount of carrier gas. There is no mechanical contact or high-pressure impact, preventing resin particle damage and contamination. Spraying parameters can be flexibly adjusted to adapt to the spraying needs of different types and application scenarios of polishing resins, and it is compatible with automated large-scale production lines.

For the spraying needs of polishing resins, Cheersonic ultrasonic spraying machines demonstrate four core advantages, helping enterprises achieve large-scale, high-quality mass production. First, ultra-precise and uniform coating, with a coating uniformity of over 99% and a thickness deviation of ≤±1%, effectively ensuring the adsorption performance and resistivity stability of the polishing resin, meeting the stringent standards of ultrapure water preparation. Second, low-pollution protection, with clean spraying throughout the process, eliminating the introduction of impurities and moisture, avoiding polishing resin contamination and delamination, balancing coating adhesion and resin integrity, and improving product yield. Third, high material utilization, reaching over 95%, significantly reducing waste of expensive polishing resin and spraying slurry, lowering preparation and application costs, and meeting the economic needs of large-scale industrial production. Fourth, excellent mass production adaptability, supporting automated continuous spraying and cleanroom compatibility, seamlessly integrating into large-scale polishing resin production lines, adapting to resin beds, precision components, and other carriers for seamless coating without dead angles, solving the problems of low efficiency, severe pollution, and poor consistency of traditional processes.

Currently, Cheersonic ultrasonic spraying machines are widely used in polishing resin spraying applications, covering core areas such as semiconductor ultrapure water preparation, precision device polishing, and resin mold preparation. They are compatible with various mainstream polishing resins, helping companies solve problems such as resin contamination, particle breakage, and low yield caused by traditional spraying processes, achieving breakthroughs in high-quality preparation and large-scale application of polishing resins.
