1. different raw materials and processes
glass wool production process:
centrifugal glass wool is made of glass as the main raw material and then mixed with other various auxiliary materials according to a certain ratio and then sent to the glass melting furnace for full melting. the melted solution is discharged through the leakage plate and enters the centrifuge. driven by a high-speed centrifuge, the centrifuge rotates the glass into a thin glass flow. under the action of a high-temperature and high-speed flame, the glass flow is further stretched into fibers, and then an atomized binder is applied. under the action of the negative pressure wind, the fibers with the resin binder adhered to the moving mesh belt to form a uniform cotton felt, and then the thermosetting oven was used to complete the curing process. the product was shaped and cut after being shaped. order the product and then pack it.
rock wool products are made of fine basalt as the main raw material. after high temperature melting, the inorganic fiber is made from high-speed centrifugal equipment, then special adhesive and dustproof oil are added to the felt by the swinging belt and the fiber arrangement structure is changed by special equipment. finally, the new lightweight insulation material made by curing and shaping can be processed into rock wool board, rock wool seam felt, rock wool shell and other products according to different purposes.
2, product performance is different
glass wool has lower bulk density, less slag content, lower thermal conductivity, longer service life and higher fiber toughness. however, the highest temperature of rock wool is about 600 degrees celsius, and glass wool is only about 260 degrees celsius.
3, the product uses different
glass wool is generally used for insulation parts below 200 degrees celsius. it is mostly used for the insulation of general buildings or low temperature pipes. rockwool is generally used for insulation parts with a temperature of 500 degrees celsius. it is mostly used for the insulation of high temperature heat pipes or electric equipment.
