I. Product Overview
Based on the phase change energy storage mechanism, RFT self-controlled phase change energy storage material has dual functions of hot melting and thermal resistance, which is different from the single thermal resistance of traditional thermal insulation materials. The traditional building external wall insulation system does not have hot melt property, which leads to large indoor temperature fluctuation. Therefore, the traditional building insulation material technology does not mean energy saving, on the contrary, it also brings new energy waste. For example, what does it feel like to wear a big cotton-padded jacket in the sun in hot summer? Similarly, in hot summer, indoor heat cannot be dissipated due to heat preservation, which leads to greater waste of air conditioning energy for heat dissipation.
RFT self-controlled phase change energy storage material has high heat capacity, which can store the solar radiation heat that enters the room through the window in winter and release the stored heat indoors at night, thus greatly saving heating energy consumption; In summer, it can not only effectively prevent outdoor heat from entering the room through the building wall, but also absorb indoor peak heat to prevent indoor overheating. After the outdoor temperature drops at night, the heat of the outer envelope can be quickly dissipated, so as to keep the indoor temperature suitable and effectively improve the indoor thermal environment, thereby reducing the energy consumption of air conditioning and reducing greenhouse gas emissions.
The RFT self-controlled phase change energy-saving materials have been appraised by the National Technical Supervision Center of Building Materials Industry, and tested by the National Quality Supervision, Inspection and Testing Center of Building Materials Industry: "Latent heat value, dry apparent density, compressive strength, linear shrinkage, combustion performance, moisture flow density of water vapor and other items meet the requirements of Q/Q/Q/Q/CYBFT003-2006《 RFT self-controlled phase change energy-saving materials". The latent heat value of pure phase change material is 240.44 Joule/g, and the sample thickness is 38 mm.
The heat transfer coefficient is 0.56 w/(m2 k), and the equivalent thermal conductivity is 0.027 w/(m k). "
The excellent performance of RFT self-controlled phase change energy storage materials has been verified by many projects and gained a good reputation. For example, the real estate development company, the builder of Gangxin residential district, said in writing in the feedback of the return visit: "This material has remarkable characteristics, advanced technology, fast construction and low comprehensive cost. After the on-site material sampling inspection, it fully meets the national standards and is an ideal thermal insulation product. It is suggested that this product should be popularized in the construction industry.
Second, the material characteristics
By using the mechanism of phase change and temperature adjustment, thermal energy can be stored through the phase change of energy storage medium. When the ambient temperature is lower than a certain value, the substance condenses from liquid to solid, releasing heat; On the contrary, melting from a solid to a liquid can absorb heat and form a relative equilibrium at room temperature.
The phase change material can collect excess heat, release it smoothly in time, and the gradient value changes little, effectively reducing the loss and stabilizing the room temperature.
Power load "Peak-clipping Pinggu" can make full use of low-valley electricity price, reduce electricity cost and energy waste by using phase change temperature regulation mechanism, and obtain considerable social and economic benefits.
Using the mechanism of phase change temperature regulation, it has a wide promotion effect on building household heating, and can play a balanced adjustment role on room temperature, summer heat insulation and winter warmth.
Third, comprehensive advantages.
Double thermal insulation-the application of phase change additives has produced double functions of hot melting and thermal resistance, which is different from the single thermal resistance of traditional thermal insulation materials.
Fire-proof and nonflammable-it is determined to be a class A nonflammable material, and its use is not limited by the scope, which meets the fire protection requirements.
Environmental protection-determined to be non-toxic, tasteless, non-radioactive and non-corrosive.
Dense and hydrophobic-it has hydrophobic function, and will not be loose, powdery and deformed after being soaked in water for a long time. Effectively avoid the shortcomings that the traditional insulation layer becomes soft after moisture absorption and is easy to be separated from the wall.
High strength and compressive strength-the material has a network structure and reacts with carbon dioxide and moisture in the air to form a protective layer on the surface, forming high compressive strength; The base course in the material can form a highly permeable whole with the wall, and its dry adhesion and wet adhesion protection rates are better than those of similar products, which can meet the bond strength requirements of exterior wall bricks of high-rise buildings.
Durable weatherability-inert materials can effectively avoid the tearing damage of thermal insulation layer caused by environmental temperature difference stress and negative wind pressure, reflecting its firm bonding and long service life.
Sound absorption and noise reduction-multi-stage non-penetrating hollow structure, which slows down the propagation of vibration sources and impact sound waves and effectively reduces noise decibels. Used for home walls, ceilings, floors and other parts with sound insulation effect.
Bacteriostasis and alkali prevention-contains pure natural fragrance and alcohol components, and has the functions of expelling insects, deodorizing and preventing alkali precipitation.
Simple construction-single component, on-site seasoning, hand plastering, convenient, and also an ideal substitute for plastering internal and external walls of various buildings.
Economical and practical-low comprehensive cost, more economical and practical than similar products.
Fourth, the scope of application
It is widely used for internal and external thermal insulation of external walls, roofs, partitions, stairs, ceilings and other parts of industrial and civil buildings that need thermal insulation.
