The lightweight wall panel is a one-time composite product formed by using a calcium silicate board as a panel and a light core material in the middle. It is a non-load-bearing lightweight composite board for wall construction.
The sandwich wall panel is solid overall, and the lightweight and thin body can improve the practical area of the house and reduce the structural load of the building. The strength of the board can resist impact, strong hanging force, heat insulation, fireproof and waterproof, can be slotted arbitrarily, and the flatness is high without the need to use water and sand. It has the advantages of sound insulation and fire-fighting utility functions, fast installation and fast speed, etc. It is a comprehensive advantage that other wall materials cannot match.
The sandwich wall panel can reduce the occupied area of the wall, improve the seismic capacity and safety performance of the building, reduce the transportation cost, and construct the civilized construction on the site. The lightweight partition board can be recycled and reused, and the short-term construction period can improve the economic benefits and reduce the comprehensive cost.
Cost - efficient Material Usage
The combination of EPS and cement optimizes material usage, reducing waste during production.
Economical in terms of raw materials, providing a cost - effective building solution.
Structural Stability
The panels' construction offers excellent stability, making them suitable for tall buildings where stability is crucial.
Helps in distributing loads evenly across the building structure.
Eco - friendly Production Process
The production of EPS cement sandwich panels involves relatively low - energy manufacturing processes.
Reduces the overall carbon emissions associated with building material production.
EPS cement sandwich panels are significantly lighter compared to traditional masonry materials. The EPS core, with its low density, contributes to the overall lightness of the panel. This makes transportation easier and reduces the load on the building's foundation, enabling the construction of taller and more complex structures.
High Strength
Despite being lightweight, the combination of the outer cement layers and the EPS core results in a panel with high strength. The cement layers provide rigidity and can withstand lateral forces such as wind and seismic loads, while the EPS core offers support and shock absorption.
Good Fire Resistance
Although EPS is combustible, the outer cement layers act as a fire - resistant barrier. With the addition of fire - retardant additives in the production process, these panels can meet different fire - rating requirements. They can prevent the spread of fire for a certain period, providing valuable time for evacuation in case of a fire emergency.

2 Saw board: According to the requirements, the machine can be arbitrarily cut and the width and length of the wall board can be adjusted to reduce the wall panel loss rate.
3 sizing: Use cement and medium sand (1:2) and add construction glue to make a paste. First use the water to brush the concave and convex grooves of the wet wallboard, then apply the polymer mortar to the concave and convex grooves of the wallboard and the floor baseline. .
4 Loading the board: Move the wall board with the good mortar to the loading position, raise the baseline position up and down, and use the iron shovel to lift the wall board from the bottom to make the board and the board tight.
5 In place: Firmly press the wallboard to squeeze the mortar out of the joint to ensure that the mortar is full and temporarily fix it with a wooden wedge.
6 Correction: Check the straightness of the flatness and verticality of 2 meters: the iron shovel adjustment, and then use the wooden wedge and the steel bar to fix it up and down.
7 Stapling: The connection between the wallboard and the wallboard must be anchored with Φ6×200mm steel bars inclined at 45°.
8 Fixing: After correcting with both sides of the 30×30mm wooden wedge, drill the hole at the 45° angle with the impact drill at the 45° angle, and then anchor with Φ6×200mm steel.
9 Grouting: Install the calibrated wallboard with cement mortar (1:2) and add the construction glue to adjust the seam between the upper and lower seams and the board to the polymer paste, and pull out the wooden wedge. The mortar is filled.
10 Slotted embedding pipe: If you want to embed dark pipeline, switch box, etc., you can install it with impact drill or portable electric saw cutting slot, and then fill it with mortar polymer after installation.
11 Door frame: The door frame can be covered with a splint directly on the wall panel, anchored with iron nails and the wall, and decorated with a cover.
12 Plastering Paint: Finally, apply the top coat. If the tile is attached, there is no need to scrape the ash, and the tile can be directly attached to the wallboard with the cement slurry, or the wallpaper, the wood slab, etc. can be directly pasted.
