Certificate of Scientific and Technological Achievements of the Ministry of Construction of the Patent Office of the State Intellectual Property Office of the People's Republic of China (ZL031X3207) (Jianke Review [2004] No. 011)
First, the product overview
FTC self-regulating phase change energy-saving materials are compounded by a new process such as plant critical extraction, vacuum freezing layering, distillation, saponification, etc., which is a pure natural original technology new material that adjusts room temperature according to different temperature phase transition points.
This material breaks through the single thermal resistance of traditional thermal insulation materials and has two thermal insulation properties: hot melt and thermal resistance. Through the principle of binary phase change, the latent heat value of the phase change is large, the heat storage density is high, and the storage and heat release processes are similarly isothermal, and the energy saving effect is obvious. According to the scientific and technological achievements appraisal of the Ministry of Construction, experts agreed that “the product introduces a phase change energy storage mechanism, and the latent heat value is large. Through the material phase change, melting and heat absorption, condensation heat release makes the indoor temperature relatively balanced, and achieves building energy conservation and promotion. After that, there will be better social and economic benefits. The research results have advanced the technology of phase change energy storage in construction-related applications, and have advanced domestic level."
Second, the comprehensive characteristics
1. Latent heat energy saving
The phase change temperature regulation mechanism is used to realize the storage and release of thermal energy through the phase change of the energy storage medium, thereby improving the indoor thermal cycle quality. When the ambient temperature is lower than a certain value, the phase change material is solidified by the liquid to release heat; when the ambient temperature is higher than a certain value, the phase change material is melted from a solid to a liquid, absorbs heat, and makes the room temperature relatively balanced.
The 3.8cm thick FTC phase change insulation material is better than the 5cm thick extruded board insulation performance by the national authority, achieving the energy saving requirement of 65%.
The phase change material can collect excess heat, and can be smoothly released in a timely manner. The gradient change is small, and the loss is effectively reduced, and the room temperature can be stabilized.
By using the phase change thermostat mechanism, the electric load can be “cut peaks and valleysâ€, make full use of low valley electricity prices, reduce household energy costs, reduce energy waste, and have considerable social and economic benefits.
The use of phase change thermostat mechanism to heat the building households has a wide range of driving effects, especially for the room temperature of the first floor, the top floor and the corner living environment, and the summer heat insulation and winter heat preservation can play a balancing role.
In the renovation of the new building and the renovation of the old building, it overcomes the defects of wall cracks, condensation, mold, and skin.
2, safe and reliable
It is bonded to the substrate as a whole, has good randomness, no cavity, and avoids negative wind pressure tearing and falling off. Effectively overcome the problems of the ribs on the back side of the panel splicing and the detachment of the outer corners of the horns.
The organic matter in the material reacts with the free acid present in the base of the main wall to form a compound, which penetrates into the micropores of the main wall to form a common body, ensures dry adhesion, and improves the wet adhesion retention rate, and has excellent adhesion.
Raw materials such as floating beads and brucite fibers (tubular fibers) are used to form a closed hydrophobic microporous cavity structure in the structure, which serves as a phase change material carrier to ensure long-term practicality of the phase change material.
The silicon oxide tetrahedral structure of the material is not loose, non-returnable, non-powdered, and deformed in water after drying, ensuring its durable service life.
3, anti-crack and moisture
The material is solidified and dried to have a fiber-like structure, which has strong tensile force and firmness, and effectively prevents cracks from occurring.
It has the characteristics of wet respiration, which can effectively prevent the condensed water generated by the difference between the outer wall substrate and the thermal insulation layer from being released due to the difference between the cold and the hot temperature, and prevent the crack on the surface of the outer layer; in winter, the outer layer is prevented from swelling and cracking. At the same time, it overcomes the hollowing and falling off phenomenon caused by the moisture of the substrate.
4, sound absorption and noise reduction
There are many layers of non-intersecting hollow structures in the material, which effectively slow down the transmission of small vibration sources, impinging sound waves, and reduce the number of noise decibels. It is used in parts such as partition walls, ceilings and floors, and has sound insulation effect to reduce the harm of urban noise to the human body.
5, sterilization and anti-virus
The phase change material contains pure natural citron and mellow substances, has deworming, sterilization and deodorization effects, and has anti-alkali function, which can improve the sanitary requirements of living environment.
6, green
The phase change energy storage energy-saving materials have been strictly tested and are environmentally friendly products that are free from corrosion, pollution, radiation, odor and toxicity.
7, fire does not burn
The phase change materials have been specially tested as Class A non-combustible materials, and the scope of use is not limited, which meets the fire protection requirements of various buildings.
8, simple construction
The insulating layer can replace the base plaster layer, saving material and labor costs for substrate processing.
Third, the scope of application
FTC phase change energy storage energy-saving materials are suitable for industrial and civil buildings, exterior insulation of various buildings (paint or tiling, etc.); external wall insulation; household partitions, ceilings, stairwells, roofs, Roofs and other parts that require sound insulation and thermal insulation.
