Sichuan Aishipaier New Material Technology Co., Ltd.

At present, with the continuous leap in the performance of electronic devices and the continuous increase in component integration, the heat dissipation problem of electronic components has become increasingly prominent. To overcome this industry bottleneck, ASPAiER Company, with its profound technological accumulation and continuous investment in innovation, has successfully developed a high-performance phase change material tailored specifically for electronic components, injecting new vitality into the stable operation and performance improvement of electronic devices. ​     The research and development process of this new type of phase change material embodies the wisdom and hard work of the company's R&D team. At the beginning of the research and development, the team deeply analyzed the pain points of the existing phase change materials in the application of electronic components. In response to the problems of insufficient thermal conductivity, unsatisfactory phase change temperature range and poor processing adaptability of traditional materials, they carried out systematic technical breakthroughs. Through the screening, blending and optimization of various basic materials, the R&D team innovatively constructed a unique material formula system.     In practical application scenarios, this phase change material performs exceptionally well. Take the CPU of a smart phone as an example. Under high-load operation, the CPU temperature can easily soar, causing the phone to experience lag, frequency reduction and other phenomena. After adopting this new phase change material from the company, the CPU temperature can be stably controlled within an appropriate range. Even when running large-scale games for a long time or handling multiple tasks, the mobile phone can maintain smooth operation without any impact on performance.     In the server field of data centers, this phase change material also plays a significant role. During the process of massive data processing, servers generate a large amount of heat, and traditional cooling methods often fail to meet the requirements. By using this phase change material in combination with high-efficiency heat dissipation modules, the core temperature of the server can be significantly reduced, enhancing the overall stability and computing efficiency of the server cluster, reducing the risk of faults caused by overheating, and providing a solid guarantee for the efficient operation of the data center.

In today's rapid development of science and technology, a magical material is quietly changing our lives - phase change materials.   Like an intelligent energy manager, it plays a key role in many fields by virtue of its unique nature.     01 Revealing phase change materials PCM - Phase Change Material is a material that changes its physical state with temperature and absorbs or releases a large amount of energy in the process.   The absorption and release of this energy comes from the reorganization of its internal microstructure. Just like when ice melts into water, it absorbs heat, and when water solidifies into ice, it releases heat, but the power of the phase change material is more powerful and efficient.     02 Diverse families of phase change materials -- Organic phase change materials Paraffin is a common organic phase change material, which will undergo solid-liquid phase change at a specific temperature. Organic phase change materials have many advantages, such as large latent heat of phase change, stable chemical properties, almost no supercooling phenomenon and small volume change when melting, so in the field of building energy conservation, it is often used to prepare thermal insulation materials to help buildings maintain comfortable temperatures in different seasons. -- Inorganic phase change materials Crystalline hydrated salts are typical, such as sodium sulfate decahydrate. This kind of material has high enthalpy of phase change, large thermal conductivity and relatively low cost. However, the problems of supercooling and phase separation limit its application. In the field of solar energy storage, researchers try to overcome these problems by modifying it to make it better store solar heat. -- Composite phase change materials In order to synthesize the advantages of various types of phase change materials, organic and inorganic phase change materials are combined by a specific process. For example, the combination of paraffin and bentonite not only improves the energy storage performance of the material, but also enhances its stability. This composite method makes up for the deficiency of a single material and makes the performance of phase change materials more excellent. ​   03 Wide range of applications -- Construction field Integrate phase change materials into building materials, such as gypsum board, concrete, etc. In the hot summer, it can absorb excess heat in the room and prevent the indoor temperature from being too high. In the cold winter, it can release the stored heat and play a role in insulation. This not only improves indoor comfort, but also significantly reduces building energy consumption, helping to achieve green building goals. -- Electronic equipment With the high degree of integration of electronic devices, the problem of heat dissipation becomes more and more serious. Phase change materials can be made into heat sinks or filled in the equipment, when the chip and other parts of the temperature rise, phase change materials quickly absorb heat and phase change, so as to effectively control the temperature of the equipment, ensure the stable operation of electronic equipment, extend the service life. -- Cold chain logistics During the transportation of fresh items such as food, maintaining a low temperature environment is crucial. The cold storage agent made of phase change materials can maintain low temperature for a long time, without frequent replacement of the ice pack, ensuring the quality and safety of the goods, and providing strong support for the efficient operation of the cold chain logistics. ​   04 Obtaining Methods ASPAiER is a professional manufacturer of phase change materials, has been developed for more than 20 years, can be customized temperature coverage -80℃ to 180℃, including gel, powder, particles and other forms of phase change materials and thickening gel series of products.

Ice packs and dry ice are both common refrigerated items, which can effectively maintain the freshness and quality of food. However, for these two kinds of refrigerated and fresh products, their heat preservation time and application methods are also different.     First, the main ingredient of the fresh-keeping ice pack is made of polymer compound gel or purified water mixture, which needs to be frozen into ice cubes in the freezer or freezer before use. The heat preservation time of this kind of fresh-keeping ice bag depends on its material and manufacturer. In general, they can maintain the freshness and quality of food for 24~48 hours.   However, if you put them in an airtight container or use them with other frozen items, they may stay fresh for longer. Second, dry ice is a relatively commonly used refrigerated preservation item, which can quickly reduce the temperature of food to a very low level, greatly reducing food spoilage. However, when using dry ice, pay special attention to the method of operation and the holding time.   The key to the thermal insulation performance of dry ice is its weight and ambient temperature. In general, the freshness and quality of food can be maintained between 24 and 48 hours. In addition, it is important to pay attention to safety when using dry ice. Because carbon dioxide gas is produced in the air, it needs to be used in an environment with good air circulation and avoid contact with the skin or mouth.     All in all, both ice packs and dry ice are very useful refrigerated items. Therefore, we need to choose the items that are suitable for us according to the actual situation, and use the correct methods and precautions of both to ensure the freshness and quality of the food, and also ensure our own safety.     Sichuan Ashpyer New Material Technology Co., Ltd.

Composite phase change heat storage technology through the composite sensible heat storage and phase change heat storage materials, to avoid the sensible heat storage technology and phase change heat storage technology many shortcomings, has become a hot spot at home and abroad in recent years, but the traditional skeleton materials use natural minerals or their secondary products, large-scale mining or processing will destroy the local ecological environment and consume a large amount of fossil energy, in order to reduce the impact of the above problems on the environment, solid waste can be used to prepare composite phase change heat storage materials.   Calcium carbide slag is acetylene, polyvinyl chloride and other industrial solid waste produced in the production process, China produces more than 50 million tons per year, and the application of calcium carbide slag in the cement industry has been saturated, resulting in a large number of calcium carbide slag open air accumulation, ditch reclamation, serious damage to the local ecological environment, urgent need to explore new resource utilization methods.     In order to absorb industrial solid waste calcium carbide slag on a large scale and prepare low-carbon and low-cost composite phase change heat storage materials, researchers from Beijing University of Civil Engineering and Architecture proposed to use calcium carbide slag as the skeleton material to prepare Na2CO3/calcium carbide slag composite phase change heat storage materials by cold-pressing sintering method, and the specific steps are shown in the figure.   Considering the deformation, surface molten salt leakage and heat storage density, although the heat storage density of sample NC4 is the largest among the three composite phase change heat storage materials, the mass ratio of the composite phase change heat storage material corresponding to sample NC5 is considered to be the optimal ratio.   Subsequently, the team analyzed the macroscopic morphology, heat storage performance, mechanical properties, microscopic morphology, cyclic stability and material component compatibility of the composite phase change heat storage materials.   And mainly obtained the following conclusions: 01 The calcium carbide slag component has good compatibility with Na2CO3, which can replace the traditional natural skeleton material to synthesize Na2CO3/calcium carbide slag composite phase change heat storage materials, and large-scale resource recycling of calcium carbide slag to realize the low-carbon and low-cost preparation of composite phase change heat storage materials.   02 The 52.5% calcium carbide slag and 47.5% phase change material Na2CO3/composite can be used to prepare a composite phase change heat storage material with excellent performance, with no change and no leakage, with a heat storage density of up to 993 J/g, a compressive strength of 22.02 MPa, and a thermal conductivity of 0.62 W/(m•K) within 100~900 °C. After 100 heating/cooling cycles, the heat storage performance of the sample NC5 remained stable.   03 The thickness of the film layer determines the inter-particle force of the skeleton material and the compressive strength of the composite phase change heat storage material, and the composite phase change heat storage material prepared under the optimal mass fraction of the phase change material has the best mechanical properties.   04 The thermal conductivity of the skeleton material particles is the main factor affecting the heat transfer performance of the composite phase change heat storage materials, and the impregnation and adsorption of the phase change materials in the pore structure of the skeleton materials improves the thermal conductivity of the skeleton material particles, thereby improving the heat transfer performance of the composite phase change heat storage materials.
