How much do you know on rock wool blanket/board?
Rock wool is made from natural rock such as basalt, diabase and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500°C. And the melts lava is then pour to high speed spinners through which the melts get into fibers.
At the same time, the phenolic binder containing silicon and mineral oil etc are sprayed onto the surface of each fiber homogeneously.
The just fiberized fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as board, mat and pipe section etc with different usage.
Features and advantages of products
A:High quality and extra fine, low slag-ball content and low coefficient of heat conductivity;
B:Wide range of bulk density (40kg-200kg/m3 ),wide range of specifications with all data being within/better than national standards;
C:Wide range of applications for construction ,petroleum,electric power metallurgy,textile,national defence,transportation and other industries. Ideal material for heat insulation and sound insulation of industrial facilities such as tank,boiler,flue ,heat exchanger,blower,vehicles and ships etc;
D:Owing to its large-scale production and advanced technology the products are salable in home market,espacially for large and key projects . the products are also sold to more than 10 countries/regions abroad.
Applications
Rock wool blanket:it's used for heat insulation and sound absorption of large pipeline,construction wall and roofs.
Rock wool glass cloth felt:it's used in large industrial equipment and construction structure with the properties of antiproperties anti--break and easy for construction.Furthermore,it has dust proof for construction wall.
Rock wool wire netting felt: it's used in strong shake and high temperature conditions.it's usually recommended to be used as insulated materials of boiler,shipping,valve and large irregular pipelines.
For other specific applications either in the industry or the construction (roofs, walls) the product can be proposed in boards. They offer higher mechanical resistance properties.
It is possible to have one face reinforced with aluminum foil either for the boards or for the blanket.
