rock wool
PRODUCT INTRODUCTION
Woqin has launched a revolutionary high-end rock wool product, which is based on an environmentally friendly formula without formaldehyde and acrylic acid, and is specially designed for the high-efficiency thermal insulation needs of industrial, commercial and residential buildings. The product has passed international certifications such as European Union CE and German TÜV, with a fire resistance limit of 2 hours (ASTM E119 standard), a thermal conductivity as low as 0.032 W/(m · K), a density of 130 kg/m ³, and a compressive strength of ≥ 50 kPa. Suitable for extreme high temperature, humidity and complex environments, it meets the requirements of green building LEED certification, and is an energy-saving and safety benchmark in the high-end market.
1. Product Overview
Woqin Company's high-end rock wool is made by melting basalt ore and natural slag at 1600 ℃ and centrifuging them into fibers. There is no formaldehyde adhesive added throughout the process, and the fiber structure is stabilized through inorganic bonding technology. Compared with traditional rock wool, its environmental friendliness, fire resistance, and durability have all been improved by more than 40%, designed specifically for users who pursue zero pollution and high safety.
2. Core Technology Highlights
(1) Formaldehyde free and acrylic acid free formula
VOC emissions are approaching zero: certified by T Ü V VOC Free in Germany, formaldehyde emissions are less than 0.01 mg/m ³ (far below the national standard of 0.08 mg/m ³), and no residual acrylic acid is detected.
Health protection: Suitable for hospitals, schools, and places for infants and young children, to eliminate the risk of respiratory irritation.
(2) Fire resistance limit of 2 hours - the ultimate defense line for building safety
Test standard: Through ASTM E119 fire resistance test, maintain structural integrity for 2 hours under a flame of 1000 ℃, and the temperature of the back fire surface only rises by ≤ 140 ℃.
Application scenarios: firewalls in high-rise buildings, fire-resistant layers in subway tunnels, explosion-proof areas in chemical plants, etc.
(3) Ultra low thermal conductivity, energy-saving efficiency increased by 30%
• Parameter comparison: Thermal conductivity of 0.032 W/(m · K) (traditional rock wool is 0.040-0.045 W/(m · K)), combined with closed cell fiber structure to block thermal bridging effect.
Economy: Taking a 1000 square meter building as an example, the annual heating energy consumption can be reduced by 15% to 20%.
(4) Compressive strength and durability
• Compressive strength ≥ 50 kPa: capable of withstanding heavy equipment loads, suitable for scenarios such as cold storage floors and rooftop photovoltaic bases.
Hydrophobic rate>99%: Water absorption rate<1% (ASTM C1104 standard), no powdering or settling in long-term humid environments.
3. Application scenarios and cases
(1) Industrial sector
Petrochemical industry: used for insulation layer of LNG storage tanks, resistant to -196 ℃ ultra-low temperature and chemical corrosion.
• Power industry: Insulation of high-temperature pipelines in thermal power plants reduces surface temperature to below 50 ℃.
(2) Commercial buildings
Green office building: Combined with BIPV photovoltaic curtain wall system, achieve LEED Platinum energy efficiency certification.
Data center: dual function of flame retardant and sound insulation, noise reduction ≥ 30 dB (ISO 717 standard).
(3) Special environment
• Ships and offshore platforms: Passed EN 13501-1 fire certification, resistant to salt spray corrosion for 2000 hours without deterioration.
4. Environmental Protection and Sustainable Development
Circular economy: 98% of waste materials in the production process can be recycled, and the crushing and regeneration rate after the end of product life is greater than 80%.
- Carbon footprint: Carbon emissions per ton of rock wool production are reduced by 35% compared to traditional processes (certified according to ISO 14064).
