1. Rock wool is an artificial inorganic fiber made from melted basalt slag wool at high temperature. It has the characteristics of light weight, small thermal conductivity, good sound absorption performance, non-combustible and good chemical stability. 2. Rock wool products include rock wool panel, rock wool blanket, rock wool pipe. 3. Good thermal insulation performance is the basic characteristics of rock wool products. Their thermal conductivity is usually between 0.03 and 0.047 W/(m·K) under normal temperature conditions (about 25 ° C).
Fiberglass cloth rock wool blanket is suitable for large-span industrial equipment and building structures, resistant to breakage and easy to construct, used in building walls is to proof dust. Aluminum foil blanket is especially suitable for original pipelines, small equipment and air conditioning system pipelines. It is often used for wall insulation of light steel structures and construction. Metal mesh sewing blanket is suitable for vibration and high temperature environments. This product is recommended for boilers, boats, valves and large diameter irregular pipes.
