Manufacturer specializing in the production of tinfoil rock wool boards

Manufacturer specializing in the production of tinfoil rock wool boards - Scope of application of rock wool insulation boards
- Rock wool products are widely used and are suitable for construction, petroleum, electric power, metallurgy, textiles, national defense, transportation and other industries. They are ideal for pipeline storage tanks, Ideal material for heat and sound insulation of industrial equipment such as boilers, flues, heat exchangers, fans, vehicles and ships.
- Rock wool insulation board uses natural rock and blast furnace slag as the main raw materials, plus a certain amount of auxiliary materials. It is melted and blown at high temperature to produce fibers, which are then used to make rock wool products. The maximum operating temperature of rock wool can reach
℃. Rock wool boards, rock wool felts, rock wool pipe shells, rock wool granular wool, etc. made from it can withstand high temperatures and are suitable for insulation of industrial high-temperature equipment. , At present, rock wool is also widely used in the external wall insulation, fire prevention, and heat insulation of buildings.
- Before the construction of external wall insulation begins, the base surface of the wall is required to meet the construction requirements of the external insulation system. If it does not meet the requirements, the following inspections and treatments are required: If the wall is dusty, powdery, or dirty, it is required to be cleaned. If there is oil stain, it is required to clean it with detergent and wait for it to dry. If the surface layer is loose, it is required to remove it. If there is a leveling layer, It is required to check on site whether the bonding strength between the leveling layer and the wall meets the requirements.
- The maximum service temperature of rock wool board refers to the maximum temperature allowed for its long-term use. The softening point of rock wool board fibers is
-, and there will be no change after long-term use at
-.
- Hard rock wool board is called hard rock wool board because its hardness is higher than rock wool board. The so-called hardness actually refers to the density of rock wool board. The higher the density of rock wool board, the better. The hardness is relatively high. The hardness of normal rock wool boards cannot be higher than that of hard rock wool boards.

- Advantages of rock wool insulation board:
- , thermal insulation performance. Good thermal insulation performance is the basic characteristic of rock wool
,
- Under normal temperature conditions
(
- Around ℃
)
- Their thermal conductivity
-, combustion performance. The burning performance of rock wool depends on the amount of flammable binder in it. Rock wool itself is an inorganic silicate fiber and is non-flammable. During the process of processing into products, organic binders or additives are sometimes added, which will have a certain impact on the combustion performance of the products.
- , sound insulation performance. Rock wool has excellent sound insulation and sound absorption properties
,
- Its sound absorption mechanism is that this product has a porous structure. When sound waves pass through the rock wool insulation board, friction is generated due to flow resistance. Part of the sound energy is absorbed by the fibers, hindering the transmission of sound waves.
