What is the bulk density of rock wool A grade fireproof material?
Rock wool board capacity of 80-200 range
General 120KG / cubic meter
Rock wool A grade fireproof material bulk density of 80Kg to 200Kg. Rock wool originated in Hawaii. When the first volcanic eruption in Hawaii Island, the island's residents found a ray of melting on the ground after the soft texture of the rock, which is the first human recognition of rock wool fiber, rock wool production process, in fact, is a simulation Hawaii volcanic eruption of this natural process, rockwool products are used high-quality basalt, dolomite as the main raw material, after 1450 ℃ high temperature melting after the use of international advanced four-axis centrifuge high-speed centrifugal fiber, while spraying a certain amount of bonding Agent, dust-proof oil, hydrophobic agent collected by the collection machine, through the pendulum method, plus three-dimensional method of cotton after curing, cutting, the formation of different specifications and use of rock wool products. Bulk weight is also known as severe. There are two kinds of understanding: 1, refers to the weight of objects within the unit volume, commonly used in engineering refers to the weight of a cubic, such as the weight per unit volume of soil. 2, said the object due to gravitational attraction and gravity characteristics, for homogeneous fluid, refers to the role in the unit volume of gravity.
60-220kg general use of different local requirements so different capacity
