How Can the Guide Wire be Unobstructed? When fighting against peripheral vascular diseases such as leg artery stenosis or blockage, doctors often use a minimally invasive technique - peripheral vascular intervention therapy. This is like carrying out a delicate "pipeline dredging" or "road repair" inside the blood vessels. In this minimally invasive surgery, a slender and flexible guide wire plays a crucial role as a "navigator". Guidewire: the [...]
What is Spray Catalyst? Spray Catalyst Concept: Spray catalyst is the process of evenly coating a substrate surface with a catalytic substance using specialized spraying equipment and methods. These catalysts can accelerate chemical reactions and have important applications in a wide range of fields. How it works: During the spraying process, the catalyst, in the form of tiny particles, is contained within the spray material and sprayed onto [...]
Spraying Precious Metal Catalysts such as Platinum and Iridium Ultrasonic Spraying Precious Metal Catalysts such as Platinum and Iridium - Cheersonic In the fields of new energy, electrolyzed water, and fuel cells, uniformly loading precious metal catalysts such as platinum and iridium on the surface of proton exchange membranes (such as Nafion membranes) is one of the key processes that affect device performance and cost. In recent years, [...]
Analysis of Flux Spraying Ultrasonic flux spraying, with its unique high-frequency vibration atomization technology, offers unparalleled advantages over traditional spraying. Using high-frequency vibrations of 20-150kHz, it evenly atomizes the flux into tiny droplets of 5-50 microns. The coating thickness can be precisely controlled to 0.1-10 microns, eliminating accumulation and leaks. This effectively avoids residual flux caused by excess flux and cold solder joints caused by insufficient flux. Material [...]
Structure of Guide Wire In the world of minimally invasive intervention therapy, doctors often need to insert slender catheters into the complex vascular network or other deep cavities of the human body, directly reaching the lesion. The key guide to completing this difficult "adventure" is a seemingly simple yet intelligent thread - the guide wire. It is not only the "pioneer" for the advancement of the catheter, but [...]
Process of Spraying Photoresist onto a Silicon Wafer Ultrasonic spraying offers significant advantages in silicon wafer processing. Using high-frequency vibrations, it atomizes the coating into uniform, tiny droplets of 5-30 microns. This creates a uniform coating on the wafer surface with precisely controllable thickness (0.1-5 microns), free of pinholes and buildup, avoiding the uneven thickness and particle agglomeration associated with traditional spraying. Ultrasonic spraying boasts a material utilization [...]
Key Material Binder for Lithium-ion Batteries In the precise construction of lithium-ion batteries, binders play a crucial and irreplaceable role. It tightly combines active substances, conductive agents, and current collectors through physical and chemical interactions, constructing a stable framework for electrodes. Its core mission is to 'buffer the volume changes of active substances during charging and discharging processes'. Taking graphite negative electrode as an example, repeated insertion and [...]
Bipolar Plate Coating for Hydrogen Fuel Cell Engine Stack We focus on the coating technology of the core component of the hydrogen fuel cell engine stack - Bipolar Plate (BPP). This is one of the key factors determining the performance, lifespan, and cost of the fuel cell stack. Why do bipolar plates require coating? The bipolar plate forms the backbone of the fuel cell stack and plays a [...]
Ultrasonic Spray Deposition Technology Ultrasonic Spray Deposition Technology: Principles, Processes, and Application Prospects Ultrasonic spraying technology is an efficient material preparation method that has emerged in recent years. Its core utilizes high-frequency sound wave energy to convert liquids into uniform and fine droplets, which are then sprayed onto the substrate surface using a gas carrier to achieve precise and controllable deposition of functional materials. This technology is widely [...]
Principles of Ultrasonic Application in Spray Pyrolysis 1. Principles of Ultrasonic Application in Spray Pyrolysis: Enhanced Atomization: Ultrasonic waves play a key role in the spray system of spray pyrolysis equipment. When ultrasonic waves act on the liquid surface, they generate high-frequency vibrations. These vibrations form capillary waves on the liquid surface. When the amplitude of the capillary waves reaches a certain level, droplets are ejected from the [...]
