Lightweight partition board has a light weight, high strength, multiple environmental protection, thermal insulation, noise, breathing the humidity, fire, rapid construction, lower cost and other advantages of the wall; only one-eighth the weight of solid brick wall, strength of C30, the thermal conductivity is only a third of solid brick wall, acoustic conductivity of only a quarter of solid brick wall, automatically adjust indoor air humidity, saving land occupied by industrial waste, industrial waste to prevent pollution of air and water saving wall cost fifteen to twenty percent, improve construction efficiency three to five times. Also lightweight partition board equipment, because it is harmless use of phosphogypsum were wet production process, without phosphogypsum dehydration and drying, so does not require expensive equipment investment, so we can say light compartment the advent of wallboard technology will open a new chapter in the comprehensive utilization of phosphogypsum lightweight partition board prices, has outstanding environmental significance. Modified lightweight partition board is light burned magnesium oxide, magnesium chloride, silicon, calcium composite cementitious material as the main body, independent research and development of Jinan by adding magnesium Ricardo GX-V series Magnesite modifier lightweight partition board , fly ash and other industrial waste, straw and other plant fibers added made of high-strength lightweight wall materials. Equipped with the rational distribution of the inner insulation, sound-absorbing inorganic foam profile or other insulation materials, wallboard pouring through the pipeline, leveling, scientific conservation, which has high degree of automation, specifications varieties.
