In addition, since it is the use of phosphogypsum harmless treatment were wet production, it does not require phosphogypsum dehydration and drying lightweight partition board equipment, so does not require expensive equipment investment, so we can say light compartment the advent of wallboard technology will open a new chapter of comprehensive utilization of phosphogypsum, 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, incorporated pf 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 lightweight partition MILL, siding pouring through the pipeline, leveling, scientific conservation, which has high degree of automation, specifications varieties . 2. The construction speed: easy to install, roof, grid plate, floor plate with lifting welding, faster method than concrete cast more than 8 times; wall using lightweight partition board assembly welding machine, than block wall five times faster than can greatly shorten the construction period. Wall paneling can be sawed, nailed, drilled, can be cut, random manufacturing building structure. 3. Good sound insulation waterproof fire performance: sound insulation up to 45dB, this sheet has a self waterproof, fire resistance of less than 2.5 hours. Anti-freeze-thaw cycles or more 25 times, moisture resistance and other test items are up to national standards.
