Lightweight partition boards are a new type of energy-saving wall material. They resemble hollow floor slabs in appearance but feature male and female tenons on both sides. Installation is simple: just stand the boards upright, apply a small amount of joint mortar to the male and female tenons, and then align and assemble them. Made from industrial waste such as dephosphorized gypsum, lightweight steel slag, fly ash, and other materials, they are cured through pressure steam treatment. Lightweight partition boards offer numerous benefits, including light weight, high strength, multiple environmental protections, thermal insulation, sound insulation, humidity regulation, fire resistance, quick construction, and cost reduction for walls. The inner layer is equipped with well-arranged thermal insulation and sound-absorbing inorganic foam materials or other insulation materials. The boards are produced through a continuous casting, leveling, and scientific curing process, with high automation and a variety of specifications and types.
