Precise Spraying – Ultrasonic Atomization Spraying Technology Leads Industry Innovation

Dec 17, 2025

In today's industrial manufacturing transformation towards high precision, low energy consumption, and environmental friendliness, spraying technology, as a key process, directly impacts product quality and market competitiveness through its upgrades and iterations. RPS-SONIC with years of experience in the ultrasonic technology field, has leveraged its profound R&D accumulation and stringent manufacturing standards to launch ultrasonic atomization spraying equipment. This equipment, with its groundbreaking technological advantages, provides efficient, precise, and environmentally friendly solutions for spraying needs across various industries, becoming a benchmark product in the industrial spraying field. The core advantage of ultrasonic atomization spraying technology lies in the ultimate control of "atomization," and RPS-SONIC products maximize this advantage. Compared to traditional pressure spraying and air spraying, this equipment utilizes high-frequency ultrasonic vibration to break liquid materials into uniform droplets at the micron or even nanometer scale. The droplet diameter can be precisely controlled within the range of 1-50 microns, and the droplet distribution uniformity far exceeds the industry average. This refined atomization effect allows for coating thickness control accuracy of ±1 micrometer during the spraying process, perfectly solving problems such as sagging, pinholes, and uneven coating that are common in traditional spraying. It is particularly suitable for precision manufacturing scenarios with extremely high requirements for coating smoothness and thickness consistency.

Another major highlight of RPS-SONIC ultrasonic atomization spraying equipment is its high efficiency, energy saving, and environmental friendliness. The equipment operates without the need for high-pressure gas-assisted atomization; it achieves liquid atomization solely through ultrasonic vibration, reducing energy consumption by 30%-50% compared to traditional spraying equipment, significantly reducing production and operating costs for enterprises. Simultaneously, due to the uniform droplet size and strong directionality, material utilization can be increased to over 90%, far exceeding the 50%-60% utilization rate of traditional spraying. This not only reduces raw material waste but also lowers the environmental pollution caused by waste paint. Furthermore, the equipment operates without the noise generated by high-pressure airflow, with operating noise below 60 decibels, creating a more comfortable production environment in the workshop and fully aligning with the modern industrial concepts of environmental protection and low carbon emissions.

 

I. The Core Role of Ultrasonic Atomization Spraying in Antibacterial Coatings in the Biotechnology Industry
* **Uniform Coverage for Highly Effective Antibacterial Protection Across the Entire Surface:** The core antibacterial requirement in the biotechnology industry is "no dead angle protection." Hangzhou Gonglu's equipment utilizes micron-level atomization technology to uniformly disperse antibacterial materials (such as silver ions, zinc oxide nanoparticles, and antibacterial peptides) into droplets. This allows for precise coverage of the complex surfaces of bio-devices and consumables-including areas difficult to reach with traditional spraying, such as micropores, crevices, and curved surfaces-forming a continuous, non-porous antibacterial coating. This uniformity avoids the problems of "localized over-thickening and clumping, and localized missed areas" common in traditional spraying, ensuring a consistent antibacterial concentration on every surface and effectively blocking the attachment and reproduction of bacteria, fungi, and other microorganisms.

 

* **Precise Thickness Control for Balanced Antibacterial and Biocompatibility:** Carriers in the biotechnology field (such as medical consumables and bioreactor components) often come into contact with human tissues, cells, or biological reagents. An excessively thick coating can affect the carrier's permeability, flexibility, or bioactivity, while an excessively thin coating cannot achieve a long-lasting antibacterial effect. Hangzhou Gonglu's equipment achieves coating thickness control precision of ±1 micrometer, allowing for precise adjustment of the antibacterial coating thickness (typically within the 1-20 micrometer range) according to different application scenarios (such as short-term medical catheters or long-term implanted bio-devices). This ensures effective release of antibacterial components while avoiding adverse effects on biological tissues or reagents, perfectly balancing antibacterial performance and biocompatibility.

 

Low-temperature atomization protects the activity of antibacterial materials: Many biological antibacterial materials (such as antimicrobial enzymes, bioactive peptides, and probiotic coatings) are temperature-sensitive. Traditional high-pressure atomization or heated atomization processes can easily lead to loss of material activity, reducing the antibacterial effect. Hangzhou Gonglu's ultrasonic atomization technology requires no heating, achieving atomization solely through high-frequency vibration. The atomization process temperature is close to room temperature (≤40℃), maximizing the preservation of the antibacterial material's bioactivity and ensuring the coating's antibacterial and bactericidal efficiency is not compromised. This is particularly suitable for spraying high-end biological antibacterial materials that are sensitive to temperature. Clean Spraying, Avoiding Secondary Contamination: The biotechnology industry has extremely high requirements for the cleanliness of the production environment. Traditional spraying methods generate mist and dust, which can easily cause cross-contamination. Hangzhou Gonglu's equipment features highly directional droplets with no excess dispersion, and the equipment operates without dust. The spraying process is clean and environmentally friendly, meeting the GMP cleanliness standards of biological laboratories and medical consumable production workshops. This avoids secondary contamination of the antibacterial coating during preparation, ensuring the biosafety of the product.

Long-lasting Adhesion, Extending the Antibacterial Cycle: By optimizing atomization parameters and coating curing processes, Hangzhou Gonglu's spraying equipment enables the antibacterial coating to form a strong chemical bond or physical adsorption with the carrier surface. The coating has strong adhesion and is not easily detached. Even under repeated washing, immersion (such as the sterilization process of medical catheters), or long-term use, the antibacterial coating can maintain its integrity, continuously releasing antibacterial components, extending the antibacterial cycle of the product, and reducing replacement frequency and usage costs. II. Specific Application Cases of Antibacterial Coating Spraying in the Biotechnology Industry

 

**Medical Consumables Antibacterial Spraying:** In the production of disposable infusion sets, urinary catheters, syringes, and other medical consumables, Hangzhou Gonglu's equipment can spray silver ion antibacterial coatings. For example, after antibacterial spraying, the coating evenly covers the inner and outer walls of the urinary catheter. The slow release of silver ions effectively inhibits the growth of pathogenic bacteria such as Escherichia coli and Staphylococcus aureus on the catheter surface, reducing the risk of urinary tract infections in patients. Clinical data shows that antibacterial urinary catheters sprayed with this equipment have an infection rate that is more than 60% lower than traditional urinary catheters. Simultaneously, the coating thickness is controlled at 3-5 micrometers, which does not affect the flexibility and ease of insertion and removal of the catheter, and the biocompatibility meets standards with no sensitizing reactions.

 

**Bioreactor Inner Wall Antibacterial Treatment:** In the bio-fermentation industry, the inner walls of fermenters and reactors are prone to bacterial growth, affecting the purity and yield of fermentation products. RPS-SONIC can spray a zinc oxide nano-antibacterial coating onto the inner walls of stainless steel or glass reactors. The coating thickness is precisely controlled at 8-10 micrometers, forming a dense antibacterial barrier that inhibits the adhesion and reproduction of contaminating bacteria. After adopting this solution, a biopharmaceutical company reduced the contamination rate during fermentation from 3.2% to below 0.5%, increased the purity of fermentation products by 15%, and significantly improved production efficiency.


Antibacterial Modification of Tissue Engineering Scaffolds: Tissue engineering scaffolds (such as cartilage repair scaffolds and skin regeneration scaffolds) need to be implanted into the human body, making them prone to postoperative infection.RPS-SONIC can spray an antibacterial peptide coating onto the surface of the scaffold (including the interior of its porous structure). Due to the small atomized droplet size (1-3 micrometers), it can penetrate deep into the micropores of the scaffold, achieving uniform spraying across the entire surface. The antibacterial peptides have targeted antibacterial properties, a strong killing effect on pathogenic bacteria, and are non-toxic to normal human cells. This technology has been applied to the production of orthopedic tissue engineering scaffolds. After implantation, the coated scaffold effectively prevents infection without affecting its biodegradability or cell adhesion activity, thus promoting tissue repair.

 

Laboratory Consumables Antibacterial Treatment: The surfaces of commonly used biological laboratory items such as culture dishes, centrifuge tubes, and pipette tips can be coated with a quaternary ammonium salt antibacterial coating using RPS-SONIC equipment, inhibiting contamination by other microorganisms during experiments. For example, the antibacterial coating thickness of culture dishes is controlled at 2-3 micrometers, which does not affect cell growth on the surface of the culture dish, while preventing airborne microorganisms from falling into the culture medium, ensuring the accuracy of cell culture experiments. A biological testing company using these antibacterial culture dishes saw a 20% increase in the repeatability of experimental results and a 70% decrease in the failure rate due to microbial contamination.

 

Dental Medical Device Antibacterial Spraying: In the production of dental instruments such as crowns, bridges, and orthodontic brackets, a nano-titanium dioxide antibacterial coating can be sprayed using Hangzhou Gonglu equipment. This coating generates hydroxyl radicals under visible light irradiation, exhibiting broad-spectrum antibacterial properties. It inhibits the growth of cariogenic bacteria such as Streptococcus mutans in the oral cavity, reducing plaque formation on instrument surfaces. Simultaneously, the coating is transparent and aesthetically pleasing, not affecting the appearance of dental instruments, and possesses strong wear resistance, withstanding the friction of daily chewing. Its antibacterial effect lasts for more than one year.

 

In addition to the above examples, Hangzhou Gonglu's ultrasonic atomization spraying equipment is widely used in bio-fields such as antibacterial coatings for wound dressings, antibacterial protection for biosensors, and antibacterial treatment of pharmaceutical packaging materials. Leveraging its precise, clean, and efficient technological advantages, it provides reliable solutions for antibacterial protection in the bio-industry.
