Product Details
The 28°C PCM: A High-Performance Material With The Remarkable
Ability To Absorb Or Release A Substantial Quantity Of Heat During
The Phase Change Process, Ensuring Efficient Thermal Regulation
Basic attributes:
1. Appearance
- It is usually a transparent liquid, and it remains liquid when the
temperature is higher than 28°C.
2. Phase change temperature
- About 28.4 °C, at this temperature the material changes from liquid
to solid or vice versa.
3. Phase change enthalpy
- About 220 to 240 joules per gram, this value indicates the amount
of heat that the material can absorb or release during the phase
change process.
4. Density
- About 0.78 grams per milliliter, this density index helps to
calculate the heat storage capacity in a specific volume.
Fields of application:
1. Textile
- By integrating phase change materials into fibers, textiles that
can adjust the warmth retention performance according to the
ambient temperature are manufactured.
2. Building materials
- Phase change materials can be integrated into building materials
such as gypsum board or walls, and their heat storage capacity can
be used to naturally adjust the indoor temperature, so as to
achieve energy-saving effects.
3. Microcapsule core material
- The phase change material is encapsulated by microcapsule
technology, which can be widely used in occasions that require fine
temperature control, such as heat dissipation of electronic
devices.
Special features:
1. Supercooling and phase separation
- Some organic phase change materials do not have the problem of
supercooling and phase separation, and their performance is
relatively stable, which makes them more reliable in practical
applications.
2. Thermal conductivity
- Although PCMs have high latent heat storage capacity, they
generally have low thermal conductivity, which may limit their
application in situations where rapid heat transfer is required.
3. Shape stability and durability
- New types of phase change materials are being developed to improve
the thermal conductivity, shape stability and durability of the
material, which are essential for long-term use and to increase the
rate of charge and discharge.
4. Enhanced heat transfer technology
- In order to improve the heat transfer efficiency of phase change
materials, researchers have explored a variety of enhanced heat
transfer technologies, such as adding fins, nanoparticles, or using
external fields and rotation.
The status quo of the industry:
1. R&D and production
- Some companies, such as Guangzhou Zhongjia New Material Technology
Co., Ltd., focus on the R&D and production of phase change
materials, which can provide high-purity phase change materials
that meet different needs, and have passed ISO 9001 certification.
2. Wide application
- The products of these companies are widely used in energy-saving
buildings, cold chain transportation, heat storage and other fields
to promote the commercialization and large-scale application of
phase change materials.
Trends:
1. Composite phase change materials
- In view of the problem that simple phase change materials are easy
to leak, researchers prepare composite phase change materials
through porous material adsorption or microcapsule encapsulation
technology, so as to improve the stability and application range of
the materials.
2. Research on low-temperature phase change energy storage
materials
- The academic community has conducted in-depth research on
low-temperature phase change energy storage materials, including
the basic characteristics of materials, classification, and
applications in temperature regulation and heat storage.
3. Future prospects
- The future development direction includes improving the thermal
conductivity of phase change materials, extending the service life,
reducing costs and expanding new application fields.
