Description

Technical Field

[0001] This utility model relates to the field of thermal pipeline support technology, specifically to an aerogel coating structure for a thermal pipeline support. Background Technology

[0002] Thermal pipelines play a vital role in industrial production and urban heating, and their supports, as key components supporting the pipelines, need to possess excellent performance to ensure the safe and stable operation of the pipeline system. In existing thermal pipeline support structures, thermal insulation performance is a problem that urgently needs to be addressed.

[0003] Traditional insulation materials and structures often struggle to maintain efficient insulation performance over a wide temperature range, leading to significant heat loss and increased energy consumption and operating costs.

[0004] Meanwhile, during long-term use, thermal pipeline supports are subject to various external forces and environmental erosion, which can easily lead to wear and corrosion, affecting the service life of the supports and the safety of the pipeline system.

[0005] Especially at the corners and edges of the support, stress concentration makes them more prone to damage. Furthermore, existing insulation coating structures have limitations in overall performance, such as insufficient strength and weak bonding with the substrate, failing to meet the increasingly stringent requirements for thermal pipeline supports.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: an aerogel coating structure for a thermal pipeline support, comprising a support substrate and an aerogel insulation coating;

[0010] The aerogel insulation coating has a thermal conductivity of ≤0.02W / (m·K) and a temperature resistance range of -200℃ to 600℃.

[0011] The thickness of the aerogel insulation coating is 1-3mm, and it is sprayed or brushed onto the surface of the support substrate to form a continuous insulation layer.

[0012] The aerogel insulation coating is also filled with fiber-reinforcing particles, and the outside of the aerogel insulation coating is also coated with a wear-resistant protective layer.

[0013] The aerogel insulation coating has a thickened area at the contact point between the support substrate and the pipe, and the thickness of the thickened area is 1.5 times that of other locations.

[0014] As an improvement, a primer layer with a thickness of 50–200 μm is provided between the support substrate and the aerogel insulation coating.

[0015] As an improvement, the aerogel insulation coating is made of a hydrophobic aerogel material.

[0016] As an improvement, the fiber-reinforcing particles are ceramic fibers or glass fibers.

[0017] As an improvement, the wear-resistant protective layer is composed of an inorganic coating.

[0018] (III) Beneficial Effects

[0019] The advantages of this utility model compared with the prior art are: the aerogel insulation coating in this application has an extremely low thermal conductivity and a wide temperature range, which enables the thermal pipeline support to effectively reduce heat loss, improve energy utilization efficiency, and reduce operating costs under different temperature environments.

[0020] The addition of fiber-reinforced particles and a wear-resistant protective layer significantly improves the strength and wear resistance of the coating, enabling it to resist wear and erosion from the external environment and extend the service life of the coating and the support.

[0021] The thickened areas at the corners and the application of a primer layer enhance the bond between the coating and the substrate, effectively disperse stress, reduce coating damage, and improve the stability and reliability of the entire support structure. Attached Figure Description

[0035] In specific implementation, this utility model

[0036] Aerogel coatings, as thermal insulation materials for thermal supports, have the following advantages and disadvantages compared to conventional materials such as rock wool, glass wool, and polyurethane: Advantages:

[0037] High thermal insulation efficiency: Aerogel itself has an extremely low thermal conductivity (usually ≤0.02W / (m·K)), and the coating form can adhere tightly to the surface of the support, reducing heat loss from gaps. It is especially suitable for supports with complex structures (such as irregular parts and corners), and its coverage is better than that of boards or rolls.

[0038] Lightweight: Its density is much lower than that of materials such as rock wool and aluminum silicate, so it hardly increases the extra load on the support structure and has little impact on the load on the support structure.

[0039] Easy to apply: Can be sprayed or brushed directly without cutting or splicing, can adapt to irregular shapes of brackets, saving construction time, and is especially suitable for on-site repairs or small space operations.

[0040] Wide temperature range: High-temperature resistant aerogel coatings can withstand temperatures from -200℃ to 600℃ (or even higher), making them suitable for medium and high temperature thermal pipeline supports. They also maintain stable performance at high temperatures and are not prone to aging.

[0041] Good waterproof and moisture-proof properties: High-quality aerogel coatings usually have a certain degree of water repellency, and their thermal insulation performance decreases less after being exposed to moisture than that of ordinary rock wool and glass wool.
