Rock wool product description:
Rock wool board is made of high-quality natural rock (such as basalt dolomite) as the main raw material. The raw material is melted by Cupola at a temperature greater than 1450 C. A small amount of binder is injected into the discounter of four-roll centrifuge to solidify and heat up, and then processed into blanket-like tubes and sheets of rock wool insulation.
insulation
Exterior wall rock wool slag ball content is low, cotton filament is slender and flexible, so low thermal conductivity has good thermal insulation effect.
Fire resistance
Because it uses natural rock as raw material, which is superior to non-flammable building thermal insulation material in high temperature resistance and does not produce toxic gases or melting droplets in fire, it is used in building structure and equipment thermal insulation to form a fire protection barrier, effectively delaying the spread of fire.
Sound absorption and noise reduction
A large number of slender and flexible rock wool fibers form multi-void interconnection structure and numerous micro-voids exist. The internal structure makes rock wool have the physical characteristics of high-efficiency sound absorption, noise reduction and elastic shock absorption. The intrusive liquid h_3H value of rock wool board on Zhengfeng external wall is neutral or weak alkaline. It is not corroded to carbon steel, aluminum alloy, copper, stainless steel, cast iron and other metal equipment as well as components of buildings.
Health and environmental protection
Exterior wall rock wool board does not contain asbestos. CFC or HCFC are not used in the production process, which is harmful to the environment. It does not have the growth environment of microorganisms and does not breed fungi.
Water-repellent and moisture-resistant
The external wall rock wool board was exposed to the environment of 50 C and 95% relative humidity for 96 hours. The volume water absorption rate was less than 0.2% and the water repellency rate was less than 1% and more than 98% according to the test quality.
Energy saving
More high-quality thermal insulation material, rock wool can greatly improve the energy-saving efficiency of the whole building and equipment, reduce the consumption of cold and heat media by more than 85%, not only save energy, but also reduce the cost of energy savings achieved by using Zhengfeng rock wool as thermal insulation material. It can simply and effectively reduce the energy production needed for heat energy, power supply and so on. It is to reduce the whole society. A direct and low-cost means of reducing greenhouse gas emissions. The passive application of high quality and high efficiency thermal insulation layer in building and equipment thermal insulation provides important emission reduction potential for the sustainable development of energy and environment.
Rock wool board is a kind of inorganic fiberboard made from basalt through a series of processes such as high temperature melting, fibrosis treatment and product post-processing. Rock wool board is a new building material with excellent insulation, sound absorption, fire resistance and light weight. Rock wool board is internationally recognized as the main energy-saving material in the "fifth conventional energy source". Every 1 m3 of rock wool board products used in equipment for thermal insulation can save an average energy of 2500 calories/hour, equivalent to saving 3 tons of standard coal per year. Every ton of rock wool board is used for thermal insulation in buildings, which can save at least one ton of petroleum energy a year.
Rock wool board has been imported from abroad since the end of 1950s, but it has been staying at the stage of producing mineral wool. Although China's mineral wool industry has developed in recent years, there is still a big gap between the overall production level and technology of rock wool products in developed countries, which can not meet the GB/T 25975-2010 standard for external wall insulation. Guorui Company has introduced advanced technology from abroad and relied on itself at the same time. As a leading technical force, Guorui's construction rock wool board fully meets the GB/T 25975-2010 standard, and meets or meets the relevant standards of developed countries such as Europe and the United States, by adopting international advanced four-roll high-speed centrifuge, pendulum technology and three-dimensional cotton spreading method and scientific and fine management.
Rock wool composite board is made of basalt and other natural ores as the main raw materials. Rock wool board is melted into fibers at high temperature, added appropriate amount of binder and solidified. Rock wool board products are suitable for industrial equipment, construction, ship insulation, sound insulation and so on.
