Differences between rock wool and glass wool

Nowadays, people have higher and higher requirements for building materials, because the quality of houses is very important, and the structure of houses directly affects our personal safety. Now let's introduce the difference between raw materials and technical production of glass wool and rock wool.

Rock wool:

Exquisite rock wool products are made of basalt as the main raw material, which is melted at high temperature, made of inorganic fibers through centrifugal equipment, then added with special adhesives and swung to form thermal insulation materials through special equipment and changes in fiber arrangement of optical fiber dustproof oil felt. According to different uses, it can be processed into rock wool board, blanket, rock wool pipe shell and other produts.

Glass wool:

Glass wool is a centrifuge which is made of glass as the main raw material and mixed with various other materials in a certain proportion. After the glass furnace is fully melted, the solution is melted and put into the casing. Driven by the rotating speed of the centrifuge, the high-speed operation of the centrifuge is to throw the glass fiber under the action of the high-temperature high-speed flame tensile flow to further the glass flow. Then spray adhesive cotton tape, under the action of negative pressure wind, is attached to the resin binder fiber and deposited on the moving mesh belt to form a unified cotton felt. Then, it is cured in a constant temperature oven. After the curing process is completed, the product type, cut into a predetermined product shape, and then packaged.
