In order to purchase suitable and high-quality glass wool (namely glass wool insulation), you need to pay attention to the correct method. Glasswool contains fiber glass wool, glass mineral wool, etc. Of course, Rockwool (namely rockwool insulation) has its own characteristics, such as sound insulation.
At present, glass wool and rock wool products have become important insulation materials. Various insulation materials are required in homes, industries and major commercial areas. The differences between glass wool and rock wool will be described in detail below.The difference in production process:Glass wool is a kind of artificial inorganic fiber. It uses quartz sand, limestone, dolomite and other natural ore as the main raw materials, and uses chemical materials such as soda ash and borax to melt into glass fibers. In the melted state, they are flung into flocculent fine fibers by external force. The fibers and fibers are three-dimensionally intertwined and entangled with each other, showing many small gaps. This gap can be regarded as a pore, so glass wool can be regarded as a porous material with good thermal insulation and sound absorption properties.
Rock wool products are made of high-quality basalt as the main raw material. After high-temperature melting, inorganic fibers are made by high-speed centrifugal equipment, and then special adhesives are added, and the fiber arrangement structure is changed by special equipment. Quality insulation material.
The difference in production performance:Glass wool has a lower specific weight than rock wool, low content of slag balls, low thermal conductivity, long service life, and high fiber toughness. However, the maximum temperature of rock wool is about 600 she’shi’du, and glass wool is only about 260 ℃.Differences in product use:Glass wool is generally used for insulation at temperatures below 200 ℃. It is mostly used for insulation of general buildings or low-temperature pipelines. Rock wool is generally used for insulation at temperatures of 500 ℃.
