Rock wool insulation board wholesale / exterior wool board wool board, based on a selection of high quality basalt as main raw material, acquired after thawing, using international advanced system of four roller centrifugal cotton process, the high temperature basaltic melt cotton rock thrown pull a non-continuous fibers 4 ~ 7μm, and then adding a certain amount of the binder in mineral wool fibers, anti-dusting oil, water repellent, after settling, curing, cutting and other processes, according to different uses made of different density series products. Range of applications in the petrochemical industry - heat insulation and sound absorbing oil, electricity, chemical industry, construction industry, noise reduction equipment - building walls, walls, roof insulation and acoustic noise insulation envelope mining industry - industrial furnaces, ovens, large-caliber tank insulation and fire prevention and ship the product specifications / Product Specifications Thickness / Thickness mm Density / Density kg / m3 60-75 80-95 100-115 120-130 140-160 170-190 200 30 √ √ √ √ 40 √ √ √ √ √ 50 √ √ √ √ √ √ √ 60 √ √ √ √ √ √ √ 80 √ √ √ √ √ √ √ 100 √ √ √ √ √ √ √ wool board is also in moisture-proof foil surface sticky, black (white) glass cloth folder tendons and moisture-proof glass fiber mat and other decorative veneer. 1, the insulation performance: rock wool insulation performance is good [1], the basic characteristics of slag wool products ,, at normal temperature (about 25 ℃) of their thermal conductivity is usually between 0.03 ~ 0.047W / (moK). 2, combustion performance: rock wool, slag wool products of combustion performance depends on how many of the flammable adhesive. Rock wool, slag wool itself belongs to inorganic silicate fibers, non-flammable, in the course of processing into products, and sometimes adding organic binders or additives, the combustion performance of these products will have some impact. 3, noise performance: rock wool, slag wool products have excellent sound insulation and sound absorption properties, their absorption mechanism is such articles having a porous structure, when the sound waves, the effect of the flow resistance due to friction, so that the acoustic energy absorbed part of the fiber, overcast hinder the transfer of sound waves. Range of applications in the petrochemical industry - heat insulation and sound absorbing oil, electricity, chemical industry, construction industry, noise reduction equipment - building walls, walls, roof insulation and acoustic noise insulation envelope mining industry - industrial furnaces, ovens, large-caliber tank insulation and fire protection of the ship flew Hebei wool board insulation Refractories Co. ___ Wholesale / exterior wool board
