High-temperature insulation coatings, as their name suggests, are designed to withstand extreme temperatures while providing excellent thermal resistance. Unlike conventional insulation materials, these coatings represent a new generation of advanced materials. With advancements in aerospace, automotive, military, oil and gas, metallurgical, power, and construction industries, the demands on insulation materials have grown significantly. These materials now need to function effectively under even harsher conditions, including higher temperatures, corrosive environments, and rapid temperature fluctuations. Traditional insulation materials often fall short of meeting these rigorous standards, leading to the emergence of high-temperature insulation coatings.
The essential characteristics of high-temperature insulation coatings include:
1. High-Temperature Resistance: These coatings must endure temperatures exceeding 600°C. Some specialized solutions, like those developed by Beijing Zhisheng Weihua Chemical Co., Ltd., can handle temperatures up to 1800°C.
2. Low Thermal Conductivity: The thermal conductivity of high-temperature insulation coatings should not exceed 0.06 W/mK. ZS-1, one such coating, boasts a thermal conductivity of just 0.03 W/mK, making it ten times more efficient than traditional materials. An 8mm thick layer of this coating on an object at 1100°C can reduce its surface temperature from 1100°C to around 100°C.
3. Environmental Friendliness: High-temperature insulation coatings must be inorganic, water-based, and free from harmful volatile organic compounds (VOCs). ZS-1 is entirely made from inorganic materials, non-toxic, odorless, and environmentally safe.
4. Energy Efficiency: As insulating and energy-saving materials, they should improve energy efficiency by at least 30%. ZS-1 can block up to 70% of heat loss, with energy savings potentially reaching 60%.
5. Corrosion Resistance: These coatings must possess a certain level of hardness and corrosion resistance. ZS-1 provides excellent protection against corrosive materials, with high hardness, pressure resistance, wear resistance, and impact resistance.
6. Precision Raw Materials: The primary raw materials used in these coatings should be finer than 50 mesh. For instance, the main component of ZS-1, nano-hollow microspheres, requires a particle size finer than 500 mesh, ensuring uniformity and consistency.
7. High Solid Content: Unlike regular paints, high-temperature insulation coatings require a solid content greater than 50%. ZS-1 boasts a solid content exceeding 90%.
8. Strong Adhesion: The adhesion of these coatings should meet level 1 standards, offering fatigue resistance and adaptability to thermal expansion and contraction. ZS-1's linear expansion coefficient reaches 12 × 10^-6, ensuring stability under varying conditions.
The performance of high-temperature insulation coatings plays a critical role in achieving energy efficiency and meeting national energy-saving goals. In China, energy conservation and emissions reduction are long-term challenges affecting sustainable development. As a leader in high-tech coatings, Beijing Zhisheng Weihua Chemical Co., Ltd. aims to contribute to industrial upgrades, technological innovation, and environmental sustainability. The company is committed to continuously enhancing ZS-1, ensuring it meets the evolving demands of industrial applications with superior performance and exceptional quality.
Industrial aluminum profiles are based on aluminum, adding an appropriate amount of silicon, copper, magnesium, zinc and other alloying elements, through a series of production processes such as high-temperature melting casting and extrusion. Aluminum itself is relatively light, the density is only about one-third of steel, so industrial aluminum profiles with its unique performance advantages and wide applicability, support the efficient operation of many industries, flourish, become a modern industrial manufacturing system in the weight of the basic material. It has the advantages of high strength, corrosion resistance, easy processing and forming, environmental protection and energy saving. Industrial aluminum profiles are widely used in the construction industry, machinery and equipment, automobile manufacturing, aerospace, and electronic products. In summary, I have reason to believe that industrial aluminum profiles will show greater potential and value in a wider range of fields!
