Aerogel Blanket used for Petrochemical industry
Aerogel insulation felt is mainly used for heat preservation of heavy oil high temperature steam injection pipeline insulation and refining equipment medium pipeline. The general temperature is between 200 °C and 600 °C.
The thin aerogel blanket can effectively reduce the amount of the outer insulation layer, Aerogels can reduce the overall cost, and has excellent water repellency, the water repellency rate is ≥98% and the PH value of Aerogel Insulation Blanket is neutral, which will not corrode the heat preservation pipe, thereby prolonging the construction. Object life and lower maintenance costs. The same thermal insulation effect, the use of Silica Aerogel Insulation Blanket can effectively reduce the volume of the construction object, thereby significantly increasing the drainage rate of the pipeline.
Today's industrial heating pipelines have temperatures ranging from tens of degrees to 600 degrees. The thermal insulation of these pipes is widely used in aluminum silicate materials and glass fiber materials. About 30 years ago, almost all of the heat insulation projects used rock wool and mineral wool materials. Up to now, rock wool insulation has been eliminated in industrial insulation projects.
In the case of little difference in construction performance and waterproof performance, the main reason for being eliminated is the difference in thermal conductivity.
The problems of Silica Aerogel Insulation Felt in China
●The thermal insulation structure is unreasonable, the insulation thickness is not standard, the insulation construction is not in place.
●The effect of heat preservation is poor and decrease obviously, which leads to the increase of maintenance cost and the increase of equipment operation cost.
●Not completely waterproof, easy to absorb moisture corrosion pipeline.
●For more than 100 degrees of high temperature pipeline, insulation layer needs at least >200mm thickness, pipe line high heat flux, heat loss.
Benefits of aerogel materials:
●The heat insulation effect is 2-5 times that of the traditional heat insulation material, the advantage is more obvious at high temperature, and the service life is longer.
●The utility model has the advantages of light weight, easy cutting and sewing, and the utility model is suitable for various pipelines and equipment with different shapes.
●Meanwhile, the utility model has the functions of sound absorption, noise reduction, buffering vibration, etc., and can improve the environmental quality and protect the equipment.
●Only the thickness of 1/2 to 1/5 can achieve the same heat insulation effect of traditional materials, the heat loss is very small, the space utilization rate is high.
