The high-temperature thermal insulation coating technology is among the most advanced in the world, with a temperature resistance capability reaching up to 1800°C. This innovative coating is a high-performance composite ceramic material designed for thermal barrier applications. Originally developed for military use, it has now been adapted for multifunctional civilian applications. Over the years, domestic coatings—such as wood coatings, coil coatings, anti-corrosion coatings, and special-purpose coatings—have achieved significant technological breakthroughs, with a growing emphasis on green and environmentally friendly solutions.
Thermal insulation coatings are now evolving rapidly, especially in the field of high-temperature insulation. These coatings are engineered to withstand extreme heat while offering excellent heat transfer resistance. Unlike traditional insulation materials, they represent a new generation of thermal protection systems, driven by advancements in materials science, aerospace, automotive, military, petrochemical, metallurgy, power generation, and construction industries.
As industrial demands grow, so do the performance requirements for these coatings. They must not only operate at higher temperatures but also function in harsher environments. Additionally, they need to be thin, resistant to vibration, fatigue, and sudden temperature changes, while maintaining strong erosion resistance. Traditional materials often fall short in meeting these modern demands, which is why high-temperature insulation coatings have become essential.
Key performance characteristics of high-temperature thermal insulation coatings include:
1. **High Temperature Resistance**: The coating must withstand temperatures above 600°C. Some advanced products, like those from Beijing Zhisheng Weihua Chemical Company, can endure up to 1800°C.
2. **Low Thermal Conductivity**: The thermal conductivity should be below 0.06 W/mK. For instance, ZS-1 high-temperature insulation coating has a thermal conductivity of just 0.03 W/mK, making it ten times more efficient than traditional materials.
3. **Environmental Friendliness**: These coatings are water-based, inorganic, and free from harmful VOCs. ZS-1 is non-toxic, odorless, and safe at both high and normal temperatures.
4. **Energy Efficiency**: The energy-saving rate should exceed 30%. ZS-1 can reduce heat loss by up to 60%, significantly improving energy efficiency.
5. **Corrosion and Pressure Resistance**: The coating must be hard and durable, protecting substrates from corrosion, wear, and impact.
6. **Fine Raw Materials**: The main components must be finely ground, typically above 50 mesh, with some materials requiring over 500 mesh for optimal performance.
7. **High Solid Content**: The solid content should be above 50%, with ZS-1 exceeding 90%.
8. **Strong Adhesion**: The coating must adhere well to surfaces, with good thermal expansion properties. ZS-1 offers excellent adhesion and durability.
ZS-1 high-temperature insulation coating is a water-based inorganic material composed of nano-ceramic hollow microbeads and silica-alumina fibers. It can withstand temperatures ranging from -80°C to 1800°C, with a thermal conductivity of only 0.03 W/mK. It effectively blocks infrared radiation and heat conduction, achieving an insulation efficiency of around 90%. It keeps internal heat inside objects and prevents external heat from affecting cold materials. It also provides noise reduction, fire resistance, wear resistance, and long service life.
Applications of high-temperature insulation coatings include:
- Reducing mold surface temperatures in injection molding machines.
- Lowering flue and exhaust pipe temperatures, improving emissions and reducing condensation.
- Insulating building walls for energy savings of over 60%.
- Protecting ladles from heat loss during transport.
- Enhancing industrial furnace efficiency by reducing heat loss by more than 30%.
- Insulating hot water tanks and dyeing tanks to cut energy costs.
- Preventing heat loss in steam and heat pipelines, achieving energy savings of up to 95%.
These coatings are revolutionizing industries by improving efficiency, safety, and sustainability. Companies like Beijing Zhisheng Weihua continue to innovate, developing high-end, eco-friendly products that meet global standards. Their commitment to quality, innovation, and brand reputation ensures they remain at the forefront of thermal insulation technology.
