In today's rapid development, new materials are increasingly becoming a new absolute development trend
So, today we will talk about the pioneer of new materials---phase change materials.
Phase Change Material (PCM - Phase Change Material) refers to a substance that changes the state of matter and provides latent heat when the temperature remains unchanged.
The process of changing physical properties is called a phase change process, and the phase change material will absorb or release a large amount of latent heat at this time.
Once this material is widely used in human life, it will become the best green carrier for energy conservation and environmental protection, and it has been listed as a national research and development utilization sequence in our country.
Phase change materials can be divided into organic (Organic) and inorganic (Inorganic) phase change materials. It can also be divided into hydrated salt (Hydrated Salts) phase change materials and waxy (Paraffin Wax) phase change materials.
Our most common phase change material is water, which changes from liquid to solid (freezes) at temperatures as low as 0°C. Water changes from solid to liquid (dissolves) when the temperature is above 0°C.
A large amount of cold energy is absorbed and stored during the freezing process, and a large amount of thermal energy is absorbed during the melting process. The greater the amount (volume) of ice, the longer the dissolution process will take.
This is one of the most typical examples of phase change materials.
The application of phase change materials in the electric heating industry is a revolutionary change from traditional electric heating to energy-saving electric heating. Phase change thermoelectric heaters are one of the representative products. Compared with traditional electric heaters, there is no need for meter expansion. You can enjoy 24-hour heating.
Therefore, in the future, floor heating based on new materials is also a new direction for gradual development. More energy-saving and more practical.
As can be seen from the above examples, phase change materials can actually act as energy storage.
This feature is of great significance in the fields of energy saving and temperature control. Therefore, phase change materials and their applications have become extensive research topics.
The biggest difference between organic phase change materials and inorganic phase change materials lies in the difference in durability and fire resistance when applied to building materials, and the latter is usually better than the former.
The introduction of phase change materials to architecture is a revolutionary development in the field of architecture. The main effect is energy saving.
Energy saving is also a major trend in future development. Now that environmentalism is prevalent, the benefits of energy conservation are self-evident.
Learning, progressing in science and technology, applying new materials to life is also one of the most important developments in development.
