Vacuum insulation panels
PRODUCT INTRODUCTION
Hebei Woqin Co., Ltd. is deeply engaged in the field of building energy conservation. The STP vacuum insulation panel it launched breaks through the limitations of traditional thermal insulation materials with aerospace - grade vacuum insulation technology. With an ultra - low thermal conductivity of 0.002 - 0.008W/(m·K), A1 - level fire - proof performance, and an ultra - long service life of 60 years, it has become a "super insulator" in the fields of construction, industry, and cold chain, helping global customers achieve multiple goals such as energy conservation, safety, and space optimization.
# I. Core Performance: Redefining the Benchmark of Thermal Insulation Materials
1. Extreme Thermal Insulation, Peak Energy Efficiency
- The thermal conductivity is as low as 0.002W/(m·K), only 1/15 of rock wool and 1/10 of polyurethane. The thermal insulation effect of 1 cm thickness is equivalent to that of 5 cm of traditional materials, significantly reducing building energy consumption and helping to meet the standards of passive houses (ultra-low energy consumption buildings).
- It can adapt to extreme temperature differences from -200℃ to 600℃, maintaining stable performance in cold storage, industrial high-temperature equipment, and aerospace scenarios, with a heat loss reduction of over 60%.
2. Lightweight, Ultra-thin, and Tough, Optimizing Space
- The thickness is only 3 - 15 mm, 70% thinner than traditional materials, releasing 5% - 10% of the building's usable area. It is especially suitable for high-density urban buildings and renovation projects of old buildings.
- The compressive strength is ≥0.2MPa, and the tensile strength is ≥0.1MPa. It can withstand a negative wind pressure of -12kPa. It has passed typhoon level 12 and earthquake resistance level 8 tests, ensuring reliable structural safety.
3. Fireproof, Moisture-proof, and Durable
- It belongs to Class A1 non-combustible materials and does not release toxic gases when burning. It has passed the national fireproof building material certification, eliminating fire hazards from the source.
- The water repellency rate is ≥99%. The seven-layer composite gas barrier film technology isolates water vapor and corrosion. It has a service life of up to 60 years in high-humidity coastal areas and cold northern regions, with a performance decay of less than 5%.
4. Green and Environmentally Friendly, Circular Economy
- 70% of the core material is industrial waste microsilica powder, and there is no Freon emission during the production process. It has obtained the three-star certification of Chinese green building materials, helping with LEED certification and the three-star rating of Chinese green buildings.
# II. Diverse Scenarios: Comprehensive Applications from Construction to Industry
1. In the Field of Building Energy Conservation
- Exterior Wall Insulation: Replace traditional rock wool/expanded polystyrene boards to achieve "ultra-thin insulation + integrated decoration". For example, the Qingdao China Railway Center (a 237-meter landmark building) uses 15-mm STP boards, reducing the exterior wall weight by 70% and energy consumption by 45%.
- Prefabricated Buildings: Cooperated with Tongji University to develop the reverse casting process, eliminating the outer leaf panel, reducing the wall thickness by 40%, shortening the construction period by 30%, and reducing the cost by 150 yuan/㎡. It is suitable for green infrastructure projects.
- Passive Houses/Ultra-low Energy Consumption Buildings: Measured in an experimental building in Bavaria, Germany, 2-cm STP boards reduced the building energy consumption to 15kWh/(m²·year), meeting the standards of passive houses.
2. In the Field of Industrial Thermal Insulation
- High-temperature Equipment: Insulate the blast furnace pipes and chemical reactors in steel plants, reducing heat loss by 50% and lowering the surface temperature to a safe range, eliminating the risk of scalding.
- Cold Chain Logistics: The VIP insulation box does not require power supply and can maintain a constant temperature of -18℃ for 120 hours in an environment of 35℃. The cold chain loss rate has decreased from 8% to 1.2%, and it has passed the GSP drug transportation certification.
3. Adaptation to Special Environments
- Cold Storage/Low-temperature Storage Tanks: Insulate LNG carriers at -162℃, increasing the cold insulation efficiency by 3 times and avoiding the failure of traditional materials due to vibration. It has passed strict international shipping tests.
- Renovation of Old Buildings: In the renovation project of the Beijing New Children's Palace, the energy efficiency can be increased by 60% without expansion, releasing 50㎡ of usable area and increasing the return on investment by 30%.
# III. Technical Advantages: Quality Assurance under Patent Protection
- Core Vacuum Chamber Technology: Vacuum is pumped to below 0.02Pa to block air convection. Combined with the silicon aerogel core material, "solid-state vacuum" insulation is achieved.
- Intelligent Production: The accuracy of the fully automated production line reaches 0.01Pa. Each board undergoes 1000 bending tests + helium mass spectrometry leak detection, with a 100% factory pass rate.
- Patent Matrix: There are a total of 325 patents (11 international patents), participating in the formulation of ISO 16478 international standards and more than 20 national/industry standards. The technology covers the entire industrial chain of core materials, processes, and construction.
