45°C Phase Change Microcapsule Can Improve The Efficiency Of Solar Energy Utilization And The Stability Of Energy Supply

Composition and structure:

• It usually consists of a capsule wall and a capsule core. The capsule wall is generally made of polymer material, which has good stability and sealing, which can protect the capsule core and prevent it from leaking. The capsule core is a phase change material that occurs when the temperature reaches 45°C.
• At temperatures below 45°C, the core is in a relatively stable state (it may be solid or liquid, depending on the properties of the PCM), and when the temperature rises to 45°C and above, the core changes from the initial state to another state (e.g., from solid to liquid, etc.).

Performance characteristics:

1. Temperature response characteristics

• When the ambient temperature reaches 45°C, the phase change material of the capsule core begins to absorb heat and undergoes phase transformation, which can absorb a large amount of heat, thereby effectively reducing the temperature of the surrounding environment and playing a role in temperature regulation.
• For example, in some specific industrial processes, if the local temperature may rise to 45°C, the phase change microcapsules can absorb excess heat and maintain a relatively stable temperature of the equipment or the environment.
• When the temperature drops, the capsule core will release heat according to the principle of phase change, which will maintain the temperature of the surrounding environment to a certain extent, and has a certain heat preservation function.

2. Good stability

• The presence of the capsule wall ensures the stability of the capsule core during the phase transition process, and even if the capsule core changes from one state to another, there will be no leakage or adverse reaction with the outside world, allowing the microcapsules to maintain the reliability and durability of their performance in various application environments.

3. The size is small

• Microcapsules are generally in the micron range, and this tiny size allows them to disperse well in various matrices, such as coatings, plastics, etc.
• It can be evenly distributed in these materials without obvious adverse effects on the overall performance and appearance of the material, and it is also beneficial to increase the contact area with the surrounding environment and improve the heat exchange efficiency.

4. Adjustability

• By selecting different capsule wall and core materials and adjusting the preparation process, the performance parameters such as phase change temperature and latent heat of phase change of microcapsules can be adjusted to meet the specific needs of different application scenarios.

Fields of application:

1. Industrial field

• In some industrial production processes with strict temperature requirements, such as electronic component manufacturing, chemical production, etc., 45°C phase change microcapsules can be applied to the heat dissipation and temperature control of equipment.
• For example, during the soldering process of electronic components, the local temperature may rise, and a heat dissipation coating containing phase change microcapsules is applied to the surface of the device, and when the temperature reaches 45°C, the microcapsules absorb the heat, prevent the equipment from overheating, and ensure the stability of the production process and product quality.
• In some industrial links that require thermal insulation, such as the storage and transportation of some chemical raw materials, when the ambient temperature is lower than 45 °C, the microcapsules can release heat to maintain the temperature stability of the raw materials and prevent them from solidifying or changing their properties.

2. Solar energy utilization

• It can be applied to solar thermal storage systems. During the day, when the heat collected by the solar collector raises the system temperature to 45°C, the phase change microcapsules absorb the heat and store it.
• When there is no sunlight at night or on cloudy days, the microcapsules release heat to heat the building or provide domestic hot water, etc., improving the efficiency of solar energy utilization and the stability of energy supply.

3. Agriculture

• In greenhouses, 45°C phase change microcapsules can be used for temperature regulation. When the internal temperature of the greenhouse rises to about 45 °C during the day, the microcapsules absorb heat to prevent the temperature from being too high and causing damage to the plants.
• When the temperature decreases at night, the microcapsules release heat to provide a relatively stable growth environment for plants, which is conducive to improving the yield and quality of crops.

4. In the field of building energy efficiency

• It can be added to building materials such as wall insulation, roofing materials, etc. In the hot weather of summer, when the internal temperature of the building is close to or reaches 45°C, the microcapsules undergo a phase change to absorb heat, reduce the indoor temperature, and reduce the energy consumption of refrigeration equipment such as air conditioners.
• In winter, it can prevent indoor heat loss too quickly to a certain extent, play a role in heat insulation, and help reduce the overall energy consumption of the building.
