Lightweight partition panels are a new type of lightweight building material that offer excellent sound insulation, thermal insulation, fire resistance, and moisture resistance. They are easy to install, making them a popular choice for many homeowners during renovations.

　　Structure of Lightweight Cement Sandwich Composite Panels

 

　　1. Cement Rock Wool Sandwich Panel

 

　　2. Cement-polystyrene particle mortar sandwich panel

 

　　3. Foamed cement sandwich panels

 

　　4. Cement-expanded perlite sandwich panel

 

　　5. Magnesium Crystal Fire-Resistant and Flame-Retardant Board

 

　　The engineering design firm or the construction contractor shall, in advance, provide the partition panel installation company with the wall plan layout and relevant technical specifications for the partitions, including the following:

 

　　1. Specify the types of partition wall panels selected and their axial distribution; the required wall thickness; the locations of doors and windows and the dimensions of their openings; as well as the routing of service pipelines and the dimensions of any chases.

 

　　2. Clearly define the functional requirements for stud partition walls, including whether waterproofing is required, whether they are intended to support heavy loads, and the measures that must be implemented.

 

　　3. Specify the fire‑resistance and sound‑insulation performance requirements for stud‑type partition walls, among other criteria;

 

　　4. Clearly define the impact‑resistance and seismic‑performance requirements for stud‑type partition walls.

 

　　Lightweight partition panels exhibit excellent hanging strength, fully meeting the standard requirements with measured values of 1000 N. They can be directly fastened with nails or expansion bolts to support heavy loads, and finished with materials such as ceramic tiles or wallpaper.

 

　　Lightweight partition panels boast excellent environmental performance: they are non‑toxic, harmless, pollution‑free, and free of radiation, making them a truly green building material. Installation is also more convenient: the joints are robust, eliminating the need for plastering; the surface can be directly painted, speeding up construction and boosting productivity by 3–5 times. Moreover, they reduce overall construction costs significantly, helping developers and contractors save money. These panels are suitable for a wide range of buildings, including hotels, office towers, shopping malls, public facilities, sports venues, schools, hospitals, factories, and more.

 

　　Experiments have demonstrated that lightweight wall panels, without any additional waterproof finish, can be bonded with cement to form a watertight tank; the back side of the panels remains dry with no visible marks, and no condensation forms even in humid conditions. The facing layer of these lightweight partition panels is an advanced waterproof board, offering excellent water‑resistance and moisture‑proofing, making them suitable for damp environments such as kitchens, bathrooms, and basements.

 

　　From traditional low‑grade plaster to lightweight plaster for statues

 

　　In the past, when applying plaster, gypsum-based undercoats were most commonly used. Manufacturers of lightweight architectural gypsum plaster typically cater to fine interior finishes, while those producing polymer‑enhanced lightweight gypsum plaster are often employed on construction sites as a cement‑based alternative for rough leveling.

 

　　Later, after foreign companies introduced lightweight gypsum to China, its development proceeded rather slowly, as cement mortar was still inexpensive at the time—after all, cost was paramount.

 

　　In 2016, environmental regulations tightened, and manufacturers of lightweight eco‑friendly plaster saw rapid growth; cement prices soared, and in 2017, sand prices also surged. By 2018, prices for virtually everything were climbing, bringing the cost of gypsum mortar nearly on par with—sometimes even below—the cost of cement mortar, thereby highlighting the growing competitiveness of gypsum mortar.

　　Spring has arrived for the entire gypsum mortar market, and machine‑sprayed gypsum is also gaining momentum (in 2018, the retarder company’s business grew by 100% or even 200% compared with 2017 or earlier).

Construction Procedures and Precautions for Rubber Powder–Polystyrene Granule Systems

1. The rubber powder–polystyrene bead insulation mortar consists of rubber powder and polystyrene beads, which are packaged separately in bags. When used, the two components are mixed with water according to a specified ratio (rubber powder to water: 1:2). This material should be mixed as needed and applied within 4 hours.

Characteristics and Key Construction Points of Polymer-Bonded Mortar

Many customers do not fully understand the characteristics and key construction considerations of polymer‑bonded mortar. In this issue, a polymer‑bonded mortar manufacturer from Shandong will share with you the distinctive features of our products.

What are the main properties of graphite polystyrene boards?

Graphite‑polystyrene insulation boards, EPS polystyrene boards, and mechanically bonded rock wool mortar composite panels. The hydrophobic rock wool board serves as the thermal insulation layer, which is anchored to the base wall using a combined adhesive‑and‑mechanical fastening system. It comprises a finishing coat made of skim coat mortar and fiberglass mesh reinforcement, topped with either a decorative mortar finish or a paint coating, forming an A‑class non‑combustible building energy‑saving insulation system.
