Glass wool production process:
Centrifugal glass wool is the glass as the main raw material and then mixed with various other auxiliary materials in a certain proportion and sent into the glass melting furnace after full melting, the melted solution flows out through the leakage plate and enters the centrifuge. Driven by the high speed centrifuge, the centrifuge runs at high speed to throw the glass into a fine stream of glass, under the action of high temperature and high speed flame, the fine stream of glass is further stretched into fibers, and then atomized binder is applied, and under the action of the negative pressure wind of the cotton net belt, the fibers attached with resin binder settle on the moving net belt, forming a uniform cotton felt, and then by the constant temperature curing oven, the curing process is completed and the product is shaped. After shaping, the product is cut into a predetermined product and then packaged.
Rock wool production process:
Rock wool products are made of exquisite basalt as the main raw material, melted at high temperature, made into inorganic fibers by high-speed centrifugal equipment, then adding special binder and dust-proof oil by swinging belt laying felt and changing the fiber arrangement structure through special equipment, and finally cured and shaped into a new lightweight insulation material. According to different applications, it can be processed into rock wool board, rock wool felt, rock wool pipe shell and other products.
2、Different product performance
Glass wool than rock wool low weight, less slag ball content, low thermal conductivity, long service life, fiber toughness, but the highest use of rock wool high maximum temperature of about 600 degrees Celsius, glass wool only about 260 degrees Celsius.
3、Different product use
Glass wool is generally used for insulation parts below 200 degrees Celsius, mostly for general buildings or low-temperature pipeline insulation, and rock wool is generally used for insulation parts with temperature at 500 degrees Celsius, mostly for high-temperature heat pipeline or electric power equipment insulation.
