On Phase Change Materials



Definition of Phase Change Materials



Phase change materials (PCMs) are substances that change their shape with temperature and provide latent heat. The process of phase change material from solid to liquid or from liquid to solid is called phase change process. At this time, phase change material will absorb or release a lot of latent heat.



Characteristics of Phase Change Materials



1. High heat storage, high efficiency, ensure hot water supply in the system
2. Remove the traditional solar water heater water tank and save space.
3. Make the installation of water heater no longer subject to floor restrictions, installation and use more convenient.
4. Make the hot water supply of the system no longer affected by the weather
5. The whole system has no power design, less heat loss, more energy-saving and environmental protection.


 



 


* Taking solid-liquid phase change as an example, when the solid phase change material is heated to the melting point, the phase change from solid to liquid occurs. In the process of melting, the phase change material is formed.
The material absorbs and stores a large amount of latent heat and keeps its own temperature constant.


 


On Phase Change Microencapsulation


 


Microcapsule



Microencapsulation can be defined as a process in which one substance surrounds or encapsulates another substance in a very small range, ranging in size from 1 micron to several hundred microns. Microencapsulation may be spherical, encapsulating the outer wall around the center, while some are asymmetrical and of different shapes, with a small number of droplets embedded in the core material of the whole microcapsule.



Microencapsulation of Phase Change Materials



Microencapsulated phase change materials can be applied almost limitlessly, and more and more applications need to use microencapsulated phase change materials. Phase change materials (PCMs) absorb or release a lot of energy by changing their morphology through the change of ambient temperature. When the temperature rises, the phase change materials begin to melt and absorb heat; on the contrary, when the temperature decreases, the phase change materials release heat.
This property of microcapsule encapsulated phase change materials can be used in military equipment, bedding, clothing, building materials, and many other products.


 



 


 Technology of Phase Change Materials in Textiles
1. Silk screen printing can be processed on any fabric. The content of phase change material can be adjusted according to the need. It can directly contact the skin and has strong washing resistance.
2. The impregnation method can process any fabric with water absorption, without changing the appearance of the fabric and having a higher calorific value.
3. The spinning of viscose staple fibers reaches 50j/g in 2.3d and 70j/g in 6.7d. The spinning of acrylic fibers and Lesser fibers is also under test.


 



 


Phase change microcapsules in other applications:
1. Functional textiles: quilts, mountaineering clothes, military uniforms, sleeping bags, etc.
2. Heat dissipation of electronic equipment: such as overheating caused by fast charging of mobile phones, etc.
3. Infrared stealth.
