Analysis of the advantages of aerogel insulation felt in the field of outdoor pipe insulation
As a building insulation, fireproof and waterproof integrated material, the aerogel insulation felt breaks the traditional building materials with a single function - waterproof, non-insulation, heat preservation, and non-waterproof. Once the waterproof layer appears leaking insulation layer, it will lose the heat preservation function. Aerogel insulation felts have significant advantages over other single-function insulation or waterproof materials:
1. Aerogel insulation felt has a multi-purpose function, and has many functions such as heat preservation, waterproof, sound insulation and vibration absorption.
2. Excellent thermal insulation performance. It is the insulation material with the lowest thermal conductivity (≤0.016) and the highest thermal resistance of all building materials in China. The thermal conductivity is only 1/3 of that of EPS foamed polystyrene board.
3. Aerogel insulation felt has ideal water repellency. The spraying method is adopted to achieve continuous and seamless joint of waterproof and thermal insulation layer, forming a seamless roof and an integral outer wall thermal insulation shell, which is excellent in waterproof and impermeability.
4. It has stable chemical properties, long service life and no pollution to the surrounding environment. It also has A1 grade non-combustible performance, which can effectively block the entry of air, the spread of fire, and good fire safety performance.
As the only new building materials for thermal insulation, fireproof and waterproof integration, the application of aerogel insulation felt in the domestic construction industry is still in the initial stage.
Aerogel insulation felt outdoor pipe insulation has high-efficiency insulation, waterproof, anti-corrosion, heat insulation, sound insulation, flame retardant, cold resistance, anti-corrosion, light capacity, high strength, simple and quick construction, and is not afraid of plant root thorns. It has become a construction and transportation. Indispensable materials such as thermal insulation, waterproof plugging and sealing in industrial sectors such as petroleum, chemical, electric power and refrigeration. Aerogel insulation blanket direct buried insulation pipe is used for indoor and outdoor pipelines, central heating pipelines, central air conditioning pipelines, chemical and other industrial pipeline insulation, cold preservation engineering, oil pipeline engineering, steam transportation and other pipeline projects. The aerogel insulation blanket directly buried thermal insulation pipe can directly reduce the heat loss in the 0.6-1.2 m frozen soil layer by more than 40% compared with the ordinary pipeline, and the working service life is more than 3-5 times higher than other adiabatic anticorrosive materials, and the service life can be It reaches 30-50 years.
