How Is The Ultrasonic Machine Dispersion The Graphene?

 

As an innovator in China's new materials field, RPS-SONIC has consistently strived to overcome technical bottlenecks in the industry. Recently, the company's independently developed "Ultrasonic graphene dispersion equipment" for producing high-quality graphene has successfully overcome the limitations of traditional preparation processes, building a critical bridge for graphene's advancement from laboratory research to industrial applications. This breakthrough also marks a new phase in the company's development of core new materials technologies.

Why focus on graphene? The application potential and industry pain points of the "king of new materials"​

 

Graphene, known as the "king of new materials" in the industry for its excellent electrical conductivity, thermal stability, and mechanical strength, boasts irreplaceable application value in power batteries, electronic thermal conductive films, high-end anti-corrosion coatings, and biomedical carriers. For example, adding graphene to power batteries can increase charging efficiency by over 30%, while its use in thermal conductive films for electronic devices can improve heat dissipation by 50%. Its market size is expected to exceed 100 billion yuan by 2025.

 

However, graphene production has long faced three core pain points, hindering industry development:

●Low purity: Traditional chemical exfoliation methods require the use of strong acids and alkalis, which easily leave residual impurities and degrade graphene performance, making it unable to meet the demands of high-end applications;

 

●Limited production capacity: Mechanical exfoliation methods rely on manual labor or precision equipment for "layer-by-layer" peeling, resulting in extremely low efficiency, with daily production capped at only grams, making it difficult to support large-scale orders;

 

●High cost: The high energy consumption and high consumables of these processes have kept the price of graphene raw materials above 10,000 yuan per kilogram, limiting the widespread adoption of downstream applications.

 

To address these industry challenges, RPS-SONIC has innovatively developed ultrasonic dispersion equipment to address the challenges of "high quality, high yield, and low cost."

 

How does ultrasonic homogenizer solve preparation problems? Core principles and technical advantages​

Unlike traditional processes involving "violent peeling" or "chemical corrosion," RPS-SONIC's ultrasonic-assisted preparation technology utilizes the ultrasonic cavitation effect to achieve "precise peeling." The technical logic can be generally understood as three steps:

 

Cavitation Energy Release: In a specific liquid environment, the tiny bubbles generated by ultrasound burst instantly, releasing localized high-pressure energy. This precisely disrupts the van der Waals forces between graphene layers (similar to the effect of "opening the pages of a book layer by layer"), thus preventing damage to the graphene structure caused by traditional mechanical grinding.

 

Dispersion System Protection: Combined with the company's independently developed, environmentally friendly dispersant, this effectively prevents the graphene sheets from reaggregating after exfoliation, ensuring uniform dispersion and improving product stability.

 

Environmentally friendly closed-loop process: Water or ethanol is used as the solvent throughout the process, eliminating hazardous waste liquids and exhaust gases, fully complying with the national "dual carbon" strategy and green manufacturing standards.

 

Pilot production has demonstrated the following advantages:

 

Purity: Graphene flakes are ≥99.5% pure, free of residual chemical impurities, meeting the requirements of high-end applications such as power batteries and semiconductors.

 

Thickness: Flake thickness is stably controlled between 1 and 5 layers, ensuring maximum electrical and thermal performance.

 

Efficiency: Single-pass production yields are three times higher than traditional liquid-phase exfoliation methods. The pilot production line can produce 50 tons annually, and capacity will increase to 200 tons/year upon commissioning of the full-scale production line.

 

Cost: Through process optimization, raw material costs have been reduced by 40%. Future large-scale production is expected to reduce the price of graphene to below 5,000 yuan/kg, significantly lowering the barrier to entry for downstream applications.​
