Hitachi Chemical Co., Ltd. (based in Tokyo, Japan, with Executive Director Tanaka and his team named "Hitachi Chemical") has recently launched a new line of wavelength-converted particle products. These innovative particles are designed for use in solar cell encapsulation sheets, aiming to boost the overall efficiency of solar power generation.
Solar energy is rapidly becoming one of the most popular renewable energy sources worldwide. Following the 2011 nuclear disaster in Japan, the country faced severe energy shortages, which led to increased interest in solar power. The introduction of the fixed-price feed-in tariff system in July 2012 further accelerated the adoption of solar technology, making it more accessible and economically viable.
Despite its growth, solar power still faces several challenges, such as dependence on sunlight intensity and duration. One of the key issues for manufacturers is how to improve the photoelectric conversion efficiency, allowing more electricity to be generated under the same light conditions.
To address this challenge, Hitachi Chemical has developed a novel wavelength conversion particle that can be integrated into solar cell encapsulation materials. This innovation helps convert ultraviolet (UV) light—typically unused in traditional solar panels—into visible light, which can then be utilized for power generation. The company has already started mass production and is offering samples to potential clients. According to estimates, using this wavelength conversion film can increase the energy conversion efficiency by approximately 2.2%.
The particles are embedded within durable acrylic resin, ensuring they do not compromise the long-term performance or durability of the solar modules. Additionally, manufacturers can easily incorporate these particles into existing production processes without any major modifications, preserving production efficiency.
Looking ahead, Hitachi Chemical plans to explore additional applications for these particles. By leveraging their ability to convert UV to visible light, the company aims to develop new functions, such as integrating them into inks for anti-counterfeit labels, signage, and other specialized uses.
In China, Hitachi Group continues to support social innovation through advanced materials and components. Beyond that, the company is also committed to contributing to the nation’s development by utilizing its expertise in IT services, water treatment, smart grids, elevators, construction machinery, and automotive equipment. Through these efforts, Hitachi aims to make meaningful contributions to China's sustainable future.
Introduction to Cotton buffing Wheel
Cotton polishing wheel is a polishing tool made mainly of cotton fabric, widely used for surface finishing of various materials such as metal, plastic, wood, etc. It is made of multiple layers of cotton fabric that are cut, stacked, pressed or sewn together. The wheel body has good flexibility and elasticity, and can be finely polished to fit the surface of the workpiece, effectively removing fine scratches, burrs and oxide layers, and improving surface smoothness.
Structure and Classification
The structure of cotton buffing wheels is mainly divided into the following types:
Classified by production process:
-Stitching type: Multi layer cotton fabric fixed by stitching, high strength, suitable for medium and coarse polishing
-Pressing type: Cotton fabric is pressed by high temperature and high pressure, with high density, suitable for fine polishing
-Special structural type: such as cotton wheels with air ducts, specially designed for high-speed polishing
Classified by fabric quality:
-Fine cotton Cloth wheel: suitable for fine polishing and mirror effect
-Twill cotton wheel: combines cutting force and polishing effect
-Velvet wheel: suitable for final polishing and super mirror treatment
Performance Characteristics
The core advantages of cotton buffing wheels are:
1. Soft material: able to conform to the shape of the workpiece and avoid scratching the surface
2. Good adsorption: can effectively carry Polishing Compound and improve polishing efficiency
3. Wide applicability: can be used for various materials such as metal, plastic, wood, etc
4. Cost effectiveness: Affordable price, easy replacement, suitable for mass production
Application scenarios
Cotton buffing wheels play an important role in the following areas:
Hardware manufacturing: surface treatment of stainless steel products and aluminum alloy parts
-Automotive industry: Polishing treatment of body parts and wheel hubs
-Jewelry: Fine polishing of precious metal surfaces
-Instrument manufacturing: Gloss treatment on the surface of copper instruments
-Furniture manufacturing: sanding and polishing of wooden surfaces
Usage Tips
To achieve the best polishing effect, it is recommended to:
1. Choose the appropriate cotton wheel type based on the material of the workpiece
2. Use with appropriate polishing agents, usually coarse first and then fine
3. Control the Polishing Machine speed, usually between 1500-3500 revolutions per minute
4. Maintain appropriate pressure and avoid excessive force that may cause heating
5. Regularly clean the residue on the surface of the cotton wheel and keep it clean
Maintenance and Safety
Proper use and maintenance can extend the lifespan of cotton wheels:
Clean the residual polishing agent and debris on the wheel surface after use
Store in a dry and ventilated place, avoiding moisture and oil stains
Check whether the wheel body is loose or damaged to ensure safe use
Wear protective goggles and gloves during operation to ensure safety
Cotton polishing wheels have become an indispensable tool in the surface treatment industry due to their softness, adaptability, and economy. Whether in industrial production or handmade production, choosing the appropriate cotton polishing wheel can significantly improve the surface quality of the product and show a more delicate luster effect.
