How to choose the right aerogel material?

First clarify the three prerequisites of use temperature, application scenarios, and service environment, then match the core indicators of thermal conductivity, temperature resistance grade, and flame retardant performance, select the right product form for construction, and finally balance compliance and full life cycle cost.
When water-based aerogel thermal insulation coatings are used for steel structure roofs, how to balance low thermal conductivity with long-term weathering and pulverization resistance?

Using hydrophobic modified nano-aerogel powder compounded with silica-acrylic emulsion system, the total thickness of the dry film is controlled within 2000-3000 μm, and the thermal conductivity can be less than or equal to 0.04W/(m · K), while meeting the 3000h resistance to artificial aging without powdering.
How can the heavy anti-corrosion coating in the marine splash area deal with the long-term cathode peeling problem under high salt spray and high initialization conditions?

The use of low surface treatment high zinc epoxy zinc-rich primer + glass flake modified epoxy intermediate paint + fluorocarbon topcoat system can meet the service requirements of ISO 12944 C5-M corrosive environment for more than 15 years.
In the integrated project of waterproof, anti-corrosion and thermal insulation, how to avoid the problem of poor compatibility between the waterproof layer and the subsequent surface layer, and the problem of biting the bottom and desticking?

The epoxy waterproof system based on the same resin is selected to match the anti-corrosion and heat insulation surface layer of the same system to ensure that the adhesion between the layers is ≥ 5MPa, and the problem of inter-layer compatibility failure is solved from the root cause.
Why can hydrophobic aerogel insulation materials reduce the risk of corrosion under insulation layer (CUI) of petrochemical pipelines at the root?

Aerogel hydrophobicity ≥ 99%, no capillary water absorption effect, can eliminate water accumulation and condensation in the insulation layer, while the thermal conductivity is only 1/5 of the traditional rock wool, and the thickness is reduced by more than 70% under the same insulation effect, which greatly reduces the water vapor penetration path and blocks the core inducement of CUI corrosion from the source.
What is the upper temperature limit for long-term safe use of aerogel insulation materials of different systems in industrial scenarios?

The upper limit of the long-term use temperature of conventional hydrophobic silica aerogels is 650 ° C, the composite ceramic fiber system can be raised to 1000 ° C, the composite alumina whisker system can stably withstand the ultra-high temperature condition of 1200 ° C, and the cryogenic aerogel can be adapted to the low temperature insulation scene of -200 ° C.
What are the core key technical indicators that polyurea materials need to meet for high-speed rail bridge decks and photovoltaic roof waterproofing projects in alpine areas?

Aliphatic polyurea system should be selected, with low temperature flexibility ≤ -40 ° C without cracks, tensile strength ≥ 20MPa, elongation at break ≥ 450%, impact resistance ≥ 10J, performance decay rate ≤ 5% after 15 freeze-thaw cycles, and excellent UV weather resistance.
What are the core market access requirements for new waterproof, anti-corrosion and thermal insulation materials exported to Central Asia, Eurasian Economic Union countries?

It is necessary to obtain the EAC certification of the Eurasian Economic Union (CU-TR certification), provide product performance test reports and certificates of origin that comply with the technical regulations of the Union, complete the product conformity declaration, and achieve "one certification, five countries pass". Some countries need to complete additional local product registration and filing.
What is the core quality control node in the integrated construction of high-temperature industrial pipeline anti-corrosion and insulation?

The core control nodes are: base rust removal up to Sa2.5 level, first construction of temperature-resistant hydrolysis-resistant polyurea anti-corrosion primer, then paving hydrophobic aerogel insulation layer, and finally waterproof outer protective layer, strict control of inter-layer adhesion, insulation layer joint sealing and drainage structure design, to prevent water vapor infiltration.
