Lightweight partition boards are a new type of energy-saving wall material. They resemble hollow floor slabs in appearance but feature male and female tenon grooves 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 fit them together. Made from industrial waste such as dephosphatized gypsum, lightweight steel slag, fly ash, and more, they are cured through frequency conversion steam pressure. Lightweight partition boards offer numerous advantages, including light weight, high strength, multiple environmental protections, thermal insulation, soundproofing, humidity regulation, fire resistance, rapid construction, and cost reduction for walls. The interior is equipped with well-arranged thermal insulation and sound-absorbing inorganic foamed materials or other insulating materials. The boards are produced through a continuous casting, leveling, and scientific curing process, with high automation and a wide variety of specifications and types.
