Cement surface rock wool composite board supplier specifications Rock wool board is made of basalt and other natural ores. The rock wool board is melted into fiber at high temperature, added with an appropriate amount of binder, and cured. Rock wool board products are suitable for thermal insulation and sound insulation of industrial equipment, buildings and ships.
In 2002, a high-tech automatic mineral wool flat plate production line was introduced, with an annual output of 12,500 m3. Rock wool boards are widely used in ships, metallurgy, power, construction and other industries.
Cement surface rock wool composite board supplier manufacturer ship insulation board: used for ship's thermal insulation and fire insulation;
Hydrophobic insulation board: used in vehicles, mobile equipment, cold storage engineering, air-conditioning pipes, and heat insulation and fire prevention in humid environments and applications that have certain requirements for moisture resistance.
Rock wool board for building has excellent fire resistance, heat insulation and sound absorption performance. It is mainly used for insulation and sound insulation of building walls and roofs; fire prevention and noise reduction of building partition walls, firewalls, fire doors and elevator shafts.
Anhui Huangshan Mortar Rock Wool Composite Board factory direct sale improves the anti-disturbance performance of the concrete by shortening the concrete interference period, reducing surface cracks and increasing the self-healing rate. The results show that when the penetration resistance is 3.528.0 MPa, the concrete is disturbed. The strength of concrete is greatly reduced.At this time, the use of coagulation-type functional additives to shorten the disturbed period of concrete can achieve good results; crack resistance and toughening additives have a certain control effect on the surface cracks of concrete; the addition of an appropriate amount of expansion agent can significantly improve Self-healing rate of concrete.
The external wall composite rock wool board products complete the production process of the entire board from sizing, main materials, spreading, compounding, and re-pressing at one time. The products produced are about 30--40 in the outer insulation process, and the main features are formed at one time. Money, insulation system, convenient installation.
Rock wool board features:
The raw material of fireproof rock wool is natural volcanic rock, which is a fireproof material for non-combustible building materials.
Thermal insulation rock wool fibers are slender and flexible, and the content of slag balls is low. As a result, the thermal conductivity is low, and it has an extremely thermal insulation effect.
Sound-absorbing and noise-reducing rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shi Keda rock wool is an excellent sound-absorbing and noise-reducing material.
Water-repellent water-repellent rock wool products have a water-repellent rate of 99.9%; extremely low water absorption and no capillary penetration.
Moisture resistance Rock wool has a volumetric moisture absorption rate of less than 0.2% under a relatively high humidity environment. According to ASTMC1104 or ASTM1104M method, the mass moisture absorption rate is less than 0.3%.
