Beijing thermal insulation rock wool pipe fireproof rock wool pipe wholesale price

Sales Telephone 3 Manager Wang 1. Thermal Insulation Performance of Rock Wool Rock wool has good thermal insulation and the basic characteristics of slag wool fabric. Under normal temperature conditions (around ℃), the thermal conductivity of rock wool is generally .3~./ between. Such thermal insulation properties make rock wool an excellent thermal insulation material. 2. The combustion performance of rock wool. The amount of flammable binder determines the flammability of rock wool. Rock wool is an inorganic silicate fiber and is non-flammable. However, during the process of processing into products, organic binders or additives need to be added. These additives will have a certain impact on the combustion performance of the products. Make the product non-flammable. 3. Sound insulation performance of rock wool Rock wool has excellent sound insulation and sound absorption properties. The sound absorption mechanism of rock wool is that this product has a porous structure. When sound waves pass through, friction is generated due to flow resistance, so that part of the sound energy is absorbed by the fibers, hindering the transmission of sound waves. Such properties make rock wool a huge advantage as a sound-absorbing material for equipment and buildings. In today's life, the sound insulation performance of rock wool is applied in many aspects. Rock wool board is made by adding an appropriate amount of binder, dustproof agent, water-repellent agent and other additives to rock wool fiber, and then pressing and solidifying it. According to the production process, rock wool boards can be divided into settlement method rock wool boards, pendulum method rock wool boards and three-dimensional method rock wool boards. Let’s take a closer look at the specific production processes of the three methods. The main production process of the settling method is that the high-temperature melt is centrifugally blown to form rock wool fibers, which are accumulated on the conveyor belt of the settling chamber. After reaching a certain thickness, they enter the curing furnace through the pressure roller, and the rock wool fibers in the settling chamber are It is a planar distribution with poor uniformity of density and binder, which affects the compressive performance and interlayer bonding strength of the board. 3 king managers of sales calls
