Exterior Wall Rock Wool Insulation Board
Yu Ou Nuo exterior wall rock wool insulation board has good heat insulation effect, low thermal conductivity, high A1 fire rating, non combustible, strong high temperature shrinkage resistance, high quality and low price, convenient construction and installation, remarkable energy saving effect, and higher quality-price ratio!
Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
Features of Exterior Wall Rock Wool Board
1. Fireproof: The raw material of rock wool board for exterior wall is natural volcanic rock, which is non combustible building material and fireproof material.
l It has the highest fireproof grade A1, which can effectively prevent the spread of fire.
l The size is very stable and will not stretch, shrink or deform in case of fire.
l High temperature resistance, melting point higher than 600 ℃.
l No smoke or combustion droplets / debris come in fire.
l No substances and gases harmful to the environment will be released in the fire.
2. Thermal insulation: The fiber of external wall rock wool board is slender and flexible, and the slag ball content is low. Therefore, it has low thermal conductivity and excellent thermal insulation effect.
3. Noise Reduction: Rock wool is an ideal sound insulation material. A large number of slender fibers form a porous connection structure, which determines that Shikeda rock wool is an excellent noise reduction material.
4. Hydrophobicity: Hydrophobic rate of hydrophobic rock wool products can reach 99.9%; water absorption is very low, no capillary permeability.
5. Moisture resistance: The volume moisture absorption rate of rock wool is less than 0.2% in the environment of high relative humidity, and the mass moisture absorption rate is less than 0.3% when tested according to the method of ASTMC1104or ASTM1104M.
6. Noncorrosive: The chemical property of rock wool is stable, the pH value is 7-8, it is neutral or weak alkaline, and it has no corrosion to carbon steel, stainless steel, aluminum and Other metal materials.
7. Safety and environmental protection: Rock wool does not contain asbestos, CFC, HFC, HCFC and other substances harmful to the environment. It will not be corroded or produce mildew and bacteria.
Precautions for rock wool board
1. We should pay attention to rain proof, stop building work in rainy days.
2. For cold insulation, it is necessary to add moisture-proof layer. Under the condition of low temperature, it is necessary to use rock wool without resin for heat insulation, and its moisture-proof layer must also be fireproof
3. When the temperature exceeds a certain temperature, such as 200 ℃, the insulation must add appropriate protection, so that the thickness and unit density of rock wool board will not change.
4. For the insulation of rock wool products for large diameter and flat plate equipment, when the temperature exceeds 200 ℃, we must bear in mind the instructions of the rock wool board manufacturer: add insulation nails, and the outer protection (with a spacing of about 400mm) should be tight.
5. Proper coating is acceptable for equipment, insulation nails and pipes to be insulated for corrosion protection. In addition, there should be no leakage. This can achieve better results.
6. If the finished rock wool board is easy to be mechanically worn in the case of outdoor thermal insulation, it should be covered with metal or plastic. Then pay attention to the joints and the Sealing of the joints, and add glue seal when necessary. The stacking part of the wrapping layer should not be less than 100 mm.
7. When the thermal insulation object is placed at 90 degrees and has a certain height, the thermal insulation layer of Exterior Wall Rock Wool Insulation Plate must have positioning pin or support ring, and the space must not be greater than 3 meters, so as to prevent the thermal insulation material from sliding downward when there is vibration.
8. In order to minimize the heat loss, the joints of rock wool board and felt must be closely connected. If there are multi-layer insulation, the cross joints need to be interwoven to avoid forming a thermal bridge, and the cold bridge must be isolated.
Application Scope of Rock Wool Board
It is widely used in petrochemical, textile metallurgy, power transportation, construction agriculture and other fields
