Fumed silica is an excellent thermal insulation material with four major advantages:
1.Silica is an excellent refractory material with excellent heat resistance performance, which can solve the problem that most insulation materials are difficult to balance with heat insulation performance and flame retardant performance, especially in the field of construction, new energy batteries and other fields.
2.The purity of fumed silica is extremely high. Due to the advantages of its production process, the impurity content in the product is extremely low, which can effectively avoid the loss of thermal conductivity such as Na and other thermal insulation performance.
3.Due to its high specific surface area and a large number of surface active functional groups, fumed silica can design products with different affinity and hydrophobic properties according to different application scenarios to meet compatibility and cooperate with other thermal insulation materials to play a role in heat insulation.
4.The thermal conductivity of fumed silica is low, and the thermal conductivity changes little with temperature, so it can significantly increase the applicable temperature range, and is suitable for medium and high temperature working conditions, especially in petrochemical and other fields.
In addition, fumed silica used in insulation materials has some other advantages: such as light weight, it can effectively reduce the weight of insulation materials; silica has high hardness and the pore structure is not easy to collapse, which can improve the mechanical strength and pressure resistance of insulation materials.
Therefore, the wide application prospects of various thermal insulation materials for gas and silicon, such as petrochemical storage tanks and pipelines; thermal insulation coatings for electric power and thermal pipelines; thermal insulation for rail transit and equipment; thermal insulation for nuclear power and aerospace; thermal insulation and noise reduction for vehicles; Building fire-proof and heat-insulating coatings; honeycomb panel thermal insulation performance upgrade, building air film thermal insulation filling; composite textile fabric thermal insulation pad; new energy battery thermal insulation, etc.
