Can be used as nuclear submarines, steam destroyer nuclear reactors, evaporators, boilers and complex high-temperature steam piping system, efficient insulation materials, can enhance the insulation effect, reduce the cabin temperature, while reducing the amount of insulation materials, increased Large space within the use of space, effectively improve the working environment. Aerogel insulation blankets can achieve better thermal insulation with lighter weight and smaller volume, which has great advantages in aerospace and aerospace applications.
Petrochemical
Aerogel insulation blanket can be used for thermal insulation of heavy oil high temperature steam injection production pipeline and medium pipeline of refining equipment. The medium temperature is between 200 ℃ and 600 ℃. Thin Aerogel products can effectively reduce the amount of external insulation, and it has excellent hydrophobicity, water repellency rate of 99.6% and PH value is neutral, will not corrode the insulation pipe, thus extending the service life of the construction object and Reduce post-maintenance costs.
The same insulation effect, the use of Aerogel insulation blankets can effectively reduce the volume of construction objects, thus significantly improving the pipeline layout. The current industrial heat transfer pipes, pipe temperature from tens of degrees to 600 degrees. At present, the most commonly used traditional insulation materials are aluminum silicate, glass wool, rock wool and so on. However, due to the more serious water absorption of these materials, the insulation will sink after absorbing water, resulting in a decrease in the thermal insulation effect. And rock wool pollution of the environment, after use can not be buried as solid waste treatment, must go through a special treatment process, so rock wool insulation has been slowly abandoned by people.
Electricity storage
In the process of energy conversion of thermal power plants, Aerogel insulation blankets can effectively reduce heat loss, save heat, improve the utilization efficiency of heat sources and ensure the economic operation of units. The choice of insulation materials should first follow the safe, non-toxic, good stability, non-radioactive, reusable principles; Second, should pay close attention to the development trend of insulation materials, and on-site construction methods to make it more rational and efficient design of firepower Power plant insulation settings.
LNG cryogenic insulation
In order to improve the safety and high efficiency of LNG transportation, it is necessary to study its cold insulation materials, and the Aerogel insulation blanket will be the most suitable adiabatic cold insulation material. Aerogel insulation blanket as the world's best insulation materials, with low thermal conductivity, good fire and water repellency, fire rating A1 level, hydrophobic rate greater than or equal to 99%; unique nano three-dimensional network structure provides Excellent high temperature stability, to avoid the traditional material due to shock and deformation caused by the accumulation of thermal insulation performance dropped sharply; the same time, the product consists of inorganic materials, non-harmful substances and the PH value is neutral, the construction of non-corrosive objects; Plastic insulation mat beyond the superior performance of traditional materials will make it the preferred material in the field of insulation and cold preservation in the future.
City heat network
Heating pipe insulation is one of the effective measures for energy saving and emission reduction. In urban centralized heating in China, hot water and steam generated by heat sources are transported to various heat users through pipes to form a heat net. Heating pipes in the heat from the heat source to the user with the user's thermal system, the heat medium pipe temperature higher than the ambient temperature, the heat pipe along the way there is a certain heat loss, therefore, insulation work to ensure the quality of heating , Energy-saving emission reduction is of great significance. Aerogel insulation blankets Buried insulation tube Suitable for conveying various media in the range of -250 ℃ -750 ℃ insulation engineering. It is widely used in urban heat supply, warm room, cold storage, coal mines, oil pipeline ports, chemical, natural gas pipelines, buried in electric power, central air-conditioning pipe insulation, cable threading pipe, steam insulation pipe insulation industry.
The purpose of heat pipe insulation is to reduce heat loss of heat medium during transportation, save energy, and improve the economy and safety of system operation. The role of insulation is to reduce energy loss, save energy, improve economic efficiency, to protect the media operating parameters to meet the production and living needs of users. For high temperature medium pipe insulation, but also reduce the temperature of the outer surface of the insulation, improve environmental working conditions, to avoid burns. Buried pipe insulation in some developed countries abroad has become a more mature advanced technology. In recent decades, China's heating engineering and technical personnel through digestion and absorption of this advanced technology, is driving the domestic pipe network laying technology to a higher level of development. More than a decade of practical achievements fully proved the laying of insulation pipe buried compared with the traditional trench and overhead laying, Aerogel insulation blankets buried pipe insulation has a very prominent advantages:
1, to reduce the total cost of the project: Aerogel buried insulation performance, heat loss is only 25% of the traditional pipe, long-term operation can save a lot of energy, significantly reducing energy costs.
2, with strong waterproof and corrosion resistance: no need to attach a trench, can be directly buried underground or water, the construction is simple and rapid, low overall cost. In low temperature conditions also has good corrosion resistance and impact resistance, can be directly buried underground frozen soil.
3, the service life of up to 20 years: the correct installation and use of network maintenance costs can be extremely low.
4, low heat loss, energy conservation: The thermal conductivity of 0.018W / m · k, than other pipe insulation materials used in the past much lower, thermal insulation effect increased by 3 to 8 times. Low thermal conductivity and low water absorption, changing the traditional trench laying heating pipe "wearing wet jacket" condition, greatly reducing the overall heat pipe heat loss, heat network heat loss of 2%, less than the international standard of 10% .
5, less land occupation, fast construction and favorable environment protection: Buried heating pipelines do not need to build huge ditches, and only need to heat insulation pipe buried in the ground, thus greatly reducing the project area and reducing the amount of earth excavation about 50 % Or more, reduce the amount of civil masonry and concrete 90%. At the same time, insulation pipe processing and digging ditches on-site parallel, just on-site joints, can shorten the construction period of about 50%.
Electronic appliances
Improve the thermal efficiency of domestic water heater, many manufacturers focus on the research of vacuum tube, open source is important, throttling can not be ignored, do a good job in the tank insulation work to improve the thermal efficiency of water heater has the same significance. Insulation material and the length of the insulation has a lot to do, within 24 hours at room temperature cooling tank control 5-7 degrees Celsius as the standard. Different manufacturers use water heater insulation materials are also different, and some inexpensive insulation materials, insulation effect is difficult to be guaranteed, which virtually increases the energy consumption of heat pump water heaters.
Household electrical and electronic equipment, a wide range of thermal insulation materials, the market appears on the latest thermal insulation materials, Aerogel insulation mat, can be said to replace the traditional thermal insulation materials the best material. Aerogel insulation blankets have excellent thermal insulation properties and good construction performance, can be used for equipment, electric heating and insulation components. The maximum temperature can be used for about 1000 ℃ insulation.
Not only that, Aerogel insulation excellent thermal insulation properties are also reflected in the following areas: low thermal conductivity, thermal conductivity at room temperature 0.016W / m · k; excellent hydrophobic properties, hydrophobic rate ≥ 99%; good Mechanical processing performance; high strength, tear resistance; high flexibility; safety and environmental non-toxic; A-class fire and so on.
