Aerogel fiberglass felt is a silica aerogel composite thermal insulation material using glass needled felt as the substrate. The characteristics and performance of the microstructure of aerogel glass fiber mat are mainly manifested in the composite aerogel agglomerate particles formed by the combination of fiber substrate and silica aerogel, embedded in a large number of micrometers with fiber material as the skeleton. In even larger pores, the actual density is 0.12~0.24g, the thermal conductivity is lower than 0.025 W/m·K, the compressive strength is greater than 2mPa, the applicable temperature is -200~1000℃, the thickness is 3 mm, 6 mm, It is 10 mm in size, 1.5 meters in width, and 40 to 60 meters in length.
Aerogel fiberglass mat has the characteristics of softness, easy cutting, low density, inorganic fire resistance, overall hydrophobicity, and environmental protection. It can replace glass fiber products, asbestos products, aluminum silicate products and traditional thermal insulation materials with poor thermal insulation properties. It is mainly used It is used in industrial pipelines, storage tanks, industrial furnace bodies, power plants, rescue cabins, warship bulkheads, directly buried pipelines, detachable thermal insulation sleeves, high-temperature steam pipelines, household appliances, iron and steel smelting non-ferrous metals and other thermal insulation and refractory fields.
The application environment of pipeline insulation is complex, including indoor insulation, outdoor insulation, and direct-buried pipeline insulation. Compared with indoor and outdoor pipeline insulation, the use of aerogel glass fiber mat material in direct buried pipeline insulation highlights the extraordinary features of aerogel. First of all, the hydrophobicity of the aerogel felt can make the pipe insulation layer waterproof, and prevent the decrease in insulation performance caused by the moisture of the insulation layer. In addition, the hydrophobicity also has a very important function, which is to prevent condensation caused by temperature differences. The porosity allows moisture to be discharged in the form of water vapor to keep the insulation layer dry. As for the anti-corrosion and fire-resistant properties of traditional inorganic fibers, aerogel glass fiber mats are fully equipped. Aerogel glass fiber felt will make the insulation space smaller, because aerogel felt has good thermal conductivity, so when the same insulation effect is achieved, the thickness or space of the aerogel felt insulation layer is smaller, which is more suitable for direct burying. In terms of pipeline insulation engineering, the use of aerogel felt to achieve the same insulation effect can reduce the thickness of the insulation layer, which means that the amount of earthwork and the construction period are shortened, and the cost of these two reductions can completely offset the use of aerogel. Felt is used as an insulation material to replace the cost of traditional insulation materials.
The convenience of construction of aerogel fiber felt can improve the efficiency of construction. After the aerogel felt is cut into a certain size, it will naturally roll up to a certain degree. For pipe insulation, the aerogel felt is cut and placed directly on the pipe. It can be installed and fixed, and the aerogel felt is light, has a certain hardness, and has a certain degree of flexibility, is not easy to break, and is very convenient to cut. Compared with the construction of traditional insulation materials, the construction efficiency can be increased by more than 30%, and it also avoids Worry about post-maintenance of using traditional insulation materials.
