High-Quality Phase Change Microcapsules - The Core Material Of Thermal Management For Efficient Energy Storage And Energy Saving
Product Introduction:
- Phase change microcapsules, also known as microcapsule phase change materials, are microcapsules composed of phase change materials by special encapsulation process.
- Phase change microcapsules are mainly composed of core material and shell material, and some surfactants are added in the preparation process.
- As a clean, reusable and efficient energy storage technology, the research and development of phase-change microcapsule materials is of great significance for energy saving, emission reduction, sustainable development and low-carbon economy.
The outstanding nature of the product:
1. Thermodynamic properties
- It has a high latent heat of phase transition, that is, a large amount of heat is absorbed or released during the phase transition, which is one of the key thermodynamic properties to achieve efficient energy storage and temperature regulation.
- In addition, the phase change temperature of the phase change microcapsules can be designed and adjusted according to different application requirements, so that they can function in a specific temperature range.
2. Physical properties
- Generally in the form of solid powder or suspended liquid, with good fluidity and processability.
- Its particle size is usually between a few microns and several hundred microns, which can be selected and controlled according to the specific application. The shell of the microcapsule has a certain mechanical strength and toughness, which can protect the phase change material inside, and withstand external pressure and friction to a certain extent.
3. Chemical properties
- The chemical properties of phase change microcapsules mainly depend on the chemical composition of their core and shell materials.
- Common core materials such as paraffin and fatty acids have good chemical stability and are not easy to react with other substances.
- Shell materials are usually selected with good chemical stability and corrosion resistance of polymer materials or inorganic materials to ensure that phase change microcapsules can be stable in different chemical environments.
4. Thermal stability
- It has good thermal stability in a certain temperature range and can keep its performance unchanged during multiple phase change cycles.
Product common application cases:
1. Temperature control of medical equipment
- Phase change microcapsules are used in heat dissipation or insulation systems of some temperature-sensitive medical devices (such as blood analyzers, in vitro diagnostic devices, etc.).
- For example, some high-precision blood analyzer requires an operating temperature of about 37°C, phase change microcapsules are integrated into the temperature regulation module of the device, when the device temperature fluctuates slightly, the microcapsule absorbs or releases heat through phase change, so that the device remains within the precise operating temperature range, ensuring the accuracy of the test results.
2. Car seats
- Phase change microcapsules are added to the padding or seat cover material of a car seat.
- When the car is exposed to sunlight and the seat temperature rises to the phase change temperature (such as 45°C), the microcapsules absorb heat, reduce the seat surface temperature, and improve the ride comfort.
- In cold weather, the microcapsules release heat to provide a certain warmth to the seat and enhance the user experience.
3. Thermal management of electric vehicle batteries
- Electric vehicle batteries generate heat during charging and discharging, which affects battery performance and life.
- Phase change microcapsules are applied to battery thermal management systems, such as wrapping thermal insulation materials containing microcapsules around battery modules. When the battery temperature reaches a phase transition temperature (such as 45°C), the microcapsules absorb heat and prevent the battery from overheating.
- In a low temperature environment, the microcapsule releases heat to help the battery maintain a suitable working temperature, improve the battery's charging and discharging efficiency and safety, and extend the battery's driving range and service life.
4. Functional home textiles
- The application of phase change microcapsules in mattresses, quilts, pillows and other home textile products.
- Taking the mattress as an example, when the person lies on the bed, the body heat makes the local temperature of the mattress reach the phase change temperature, the microcapsule absorbs heat, regulates the sleep environment temperature, reduces the number of turns caused by overheating or cold at night, and improves the sleep quality.
Packaging and storage:
1. Packing method
2. Storage method
- Dry, cool and ventilated place without sharp objects.
