Hard rock wool board pricing @News Center Director in charge of phone and fax [Note]: This number is strictly for customer inquiries only. We decline all promotional activities and sales-related calls. Rock wool board is primarily crafted from high-quality basalt as the main raw material. After being melted at extreme temperatures, it undergoes the internationally recognized four-roll centrifugal cotton process. This process transforms the basalt into fibers measuring between 4 to 7 micrometers in length. Subsequently, specific amounts of binders, dustproof oils, and water-repellent agents are mixed into the fibers. These materials are then subjected to processes such as settling, solidifying, and cutting, resulting in a diverse range of products with varying densities based on their intended use.
Applications span across various sectors: petrochemical industries utilize it for equipment insulation, soundproofing, and noise reduction in oil, electricity, and chemical facilities. In construction, it serves as insulation, soundproofing, and noise reduction for building partitions, curtain walls, roofs, and enclosures. Industries like mining and manufacturing employ it for furnace linings, ovens, large storage tanks, ship insulation, and fireproofing.
Key features of rock wool board include:
1. Surface Quality: Smooth and flawless, ensuring practicality.
2. Non-flammable: Ensures safety in fire-prone areas.
3. Thermal Load Shrinkage Temperature: Up to 643 degrees.
4. Hygroscopicity: 3.9%.
5. Organic Content: 2.9%.
Standard parameters for rock wool board: 1522. Material: colored steel plates, rock wool board. Apparent Density: 120 kg/m³. Thermal Conductivity: 0.04 W/(m·K). Maximum Operating Temperature: 80°C. Brand: Tiandi. Dimensions: 950, 1150 mm. Implementation Standards: GB. Moisture Absorption Rate: 3.9%. Made from basalt and other natural ores, rock wool board is melted into fibers at high temperatures and combined with appropriate binders, offering excellent insulation and soundproofing capabilities. Widely used in ships, metallurgy, power, and construction industries, it ensures efficient energy savings while maintaining a high cost-performance ratio.
Marine and hydrophobic rock wool insulation boards incorporate hydrophobic additives during production, providing superior moisture resistance. Marine rock wool boards are ideal for ship thermal insulation and fireproof partitions, whereas hydrophobic rock wool boards are suited for vehicles, mobile equipment, cold storage, air conditioning ducts, and environments requiring moisture control. Construction-grade rock wool boards excel in fireproofing, thermal insulation, and sound absorption, primarily used for wall and roof insulation, as well as fireproofing and noise reduction in partitions, firewalls, fire doors, and elevator shafts. The thermal insulation performance of rock wool insulation boards remains exceptional, particularly under normal temperatures, outperforming other insulation materials. Additionally, its soundproofing capabilities make it popular in Europe and North America.
When installing rock wool insulation boards, consider these points:
1. Ensure proper insulation of pipelines, keeping surfaces dry, free of grease and rust. Protective coatings may be applied when necessary.
2. To minimize heat loss, ensure all board and felt joints are tightly sealed. Stagger joints in multi-layer insulation to prevent thermal bridges.
3. For outdoor or mechanically worn areas, focus on joint integrity, using adhesive seals if needed, with overlaps of at least 100mm.
4. Add moisture-proof layers on cold surfaces, and use resin-free rock wool at extremely low temperatures, ensuring fireproofing of moisture-proof layers.
5. Over 200°C, provide adequate protection to avoid changes in thickness or bulk density due to expansion.
6. For large-diameter or flat-wall equipment exceeding 200°C, install insulation nails and ensure a tight outer cover.
7. For vertically placed heat preservation objects, use positioning pins or support rings spaced no more than 3 meters apart to prevent sliding during vibration.
8. Avoid outdoor insulation work on rainy days; if unavoidable, take rain protection measures.
Improper handling can render rock wool ineffective despite its installation.
Color steel rock wool board composite panels:
A new building material featuring colored rock wool board as the outer layer and rock wool, fireproof, and flame-retardant insulation as the core layer. It boasts lightweight design, excellent thermal insulation, sound absorption, and sealing properties. Easy to construct, it offers a shorter construction cycle, lower overall costs, bending resistance, corrosion resistance, and an attractive appearance.
Characteristics of rock wool board:
(1) Thermal Insulation: Thermal conductivity = 0.035W/m²K.
(2) High Strength: Can act as both retaining and load-bearing structures, with bending and compression resistance. Most buildings do not require beams and columns.
(3) Bright Colors: No surface finishing required. The color steel plate's anti-corrosion layer lasts 10-15 years, while the color galvanized sheet's lasts 30-45 years.
(4) Flexible Installation: Panel widths come in 950 and 1150 types. The surface can be pressed or left unpressed. Lengths are customizable per user requirements, reducing construction time by over 40%.
It is extensively used in the ceilings and partitions of steel structure workshops and portable homes.
