In the petrochemical industry, equipment and pipelines are constantly exposed to high temperatures, high humidity and complex environments. Traditional insulation materials often encounter problems such as moisture absorption failure, increased thermal conductivity and short service life. To address these challenges, hydrophobic high-silicon oxygen gel insulation blankets, as a new generation of high-performance insulation materials, are gradually becoming the preferred energy-saving solution in the petrochemical sector. 
I. Overview of Materials 
The hydrophobic high-silicon oxygen gel insulation blanket is a flexible insulation material composed of nano-sized silica as the main body and composite glass fiber felt or ceramic fiber felt as the framework. Its internal microporous structure accounts for over 90%, with pore diameters of only a few tens of nanometers, forming an "air insulation layer", which significantly reduces heat transfer. Through special hydrophobic modification treatment, it can effectively prevent water vapor penetration and moisture absorption, maintaining long-term stable insulation performance. 
II. Core Performance Advantages 
Ultra-low thermal conductivity, with significant energy-saving effect 
The thermal conductivity is as low as 0.018 - 0.022 W/m·K, which is half or even less than that of traditional rock wool or glass wool. When applied to high-temperature pipelines, storage tanks or heat exchange equipment, it can significantly reduce heat loss and improve overall energy efficiency. 
2. Water-resistant and moisture-proof, not afraid of complex working conditions 
The aerogel material is treated with a hydrophobic surface treatment, which can effectively prevent water vapor from penetrating for a long time. Even in humid or rainy environments, it does not absorb moisture, does not clog, and does not collapse, significantly extending the lifespan of the insulation layer. 
3. Excellent heat resistance performance 
It can work stably at temperatures within 600℃ for a long time, without any deformation or powdering of the structure. It is highly suitable for high-temperature oil transportation pipelines and steam systems in petrochemical plants. 
4. Reduced thickness, making construction more convenient 
Under the same insulation effect, the thickness of the aerogel insulation blanket is only half or even less than that of traditional materials. It not only saves space but also reduces the load on the equipment, and has higher installation flexibility. 
5. Environmentally friendly and safe, with long lifespan 
The material is free of asbestos, does not cause dust irritation, and does not release any volatile harmful substances. It has excellent aging resistance and can last for over 20 years. The maintenance cost in the later stage is low. 
III. Application Scenarios 
Hydrophobic high-silicon oxygen-containing gel insulation blankets are widely used in the petrochemical industry: 
High-temperature pipeline systems: such as oil pipelines, gas pipelines, and steam pipelines, aim to reduce heat loss and prevent condensation; 
Storage tanks and reaction vessels: Provide a uniform and stable insulation layer for large tanks, enhancing energy efficiency; 
Heating furnaces, heat exchange equipment: Acting as a thermal insulation barrier on the outer layer of high-temperature equipment, enhancing the safety of system operation; 
Maintenance projects for oil refineries and chemical plants: Replace old rock wool and glass wool to achieve energy-saving upgrades and renovations. 
IV. Energy Conservation and Economic Value 
Practice has shown that by adopting the aerogel insulation system, the overall heat loss of petrochemical plants can be reduced by 20% to 40%, resulting in significant annual energy savings. Moreover, due to its excellent waterproof and anti-corrosion properties, the maintenance frequency is reduced, the downtime for maintenance is shortened, and the overall usage cost is lower. 
Under the backdrop of the "dual carbon" strategy and the construction of green factories, the hydrophobic high-silicon oxygen gel insulation blanket, with its characteristics of "high efficiency and energy saving, long-term moisture prevention, safety and environmental protection", provides a systematic and intelligent insulation solution for petrochemical pipelines and storage tanks. It is not only an innovative replacement for traditional insulation materials, but also a new direction for industrial energy conservation in the future.
