Product Description
1, the introduction of rock wool board
Rock wool products take basalt and other natural rocks as raw materials. It is melted into fibers and then be hardened. During the process, suitable amount binder and oil are added. Rock wool products are widely used in shipbuilding, metallurgy, electric power, construction and other industries with good performance of fireproof, thermal insulation, acoustic insulation and energy saving. It is the ideal thermal insulation materials which has been recognized internationally.
2, the features of rock wool board
1,Good Mechanical Property
High-strength rockwool roof panel board has good compressive strength and anti-point load to ensure the smooth of roofs and meet the requirements of carrying people and equipment when constructing.
2,Fire Resistance Property
The melting point of high-strength rockwool roof board reaches 1000 degrees with good ability of shrinkage. It can effectively support building structures at the time of fire to achieve the fireproof function of 1—4 ours.
3,Thermal Insulation Property
Its content of slag ball is low and the fibers slender and flexible. So the board has low thermal conductivity and excellent thermal insulation property.
4,Environmental Property
The raw materials of rockwool board are natural rocks, do not contain any asbestons and it is harmless to human bodies. The harmful materials such as CFC and HCFC which is harmful to the environment never be used in the production process.
3, the production process of rock wool board
Rock wool is made from natural rocks such as basalt and dolomite, which are chosen with high quality. The rocks are melted in a cupola at temperature of more than 1500 degrees, then molten lava is fiberized by a spinner. The inorganic fibers and additives are bonded together using a thermosetting resin to form the final product which is cut into suitable sizes. Wired blanket, pipe cover and faced products are produced by secondary processes.
