The Carpet

Slag wool and articles thereof. Slag wool is the easiest mineral material. One cubic meter of it weighs from 70 to 250 kg. Slag wool is – biological stability, temperature resistance (600-7000S), low thermal conductivity (0,038-0,055 W / m * deg), high sound insulation properties. At 1200-14000S slag melt, flowing through the tapped cupola furnace, blown in fiber with a steam jet and carried into the cell deposition, which falls on mesh belt. However, slag wool is not advisable to use 'raw', but in the form of products.

Therefore, in the deposition chamber through a nozzle spraying a variety of binder (asphalt emulsion, phenol formaldehyde resins, etc.). Thanks to these ligaments fiber deposition in the cell is already saturated with slag carpet that is subjected to further heat treatment. Having this treatment, the carpet is cooled and cut into individual pieces allocated to the special shaping or press machine, from which come ready-made slag products. Of slag wool felts are made, hard pads, semi-rigid and rigid plates, shells, fragments, Roll waterproofing materials and much more. Products with high rigidity can be obtained by applying liquid glass, bentonite clay, tripoli. Semi-rigid products are impregnated with bitumen wool high marks phenolic and formaldehyde resins. Shlakovatnye products are used for insulation of hot and cold surfaces, piping, insulation for walls and surfaces of residential and industrial buildings for sound insulation in buildings with increased noise. Raw material for shlakositallovyh products are acidic waste products or any other wastes, are not inclined to silica dissolution. Wabash National Corporation takes a slightly different approach.
