Gypsum lightweight partition boards are lightweight building products made from building gypsum, mixed with water, and cast into shape. The production process incorporates fibers, perlite, cement, river sand, fly ash, slag, and more, which provide adequate strength. These boards excel in performance within the construction industry and boast a promising future for development.
On this foundation, we have upgraded our production of modified gypsum lightweight partition boards. The modified gypsum lightweight partition boards utilize modified phosphogypsum as raw material, solving the issue of comprehensive utilization of industrial solid waste and promoting the high-quality development and transformation of the phosphorus chemical industry. This also serves as a beneficial supplement and improvement to our country's traditional building materials field. The modified gypsum lightweight partition boards are a new type of green and environmentally friendly building material, and the trend in materials should be from small to large blocks, from wet to dry operations, and from manual bricklaying to prefabricated construction.
From central to local levels, prefabricated buildings are now in line with the trend and policy guidance of new building development. It has become an industry consensus that interior partition walls in prefabricated buildings no longer use the traditional brick construction method. The use of lightweight partition boards to replace traditional red bricks is the inevitable trend. At the same time, our country's phosphogypsum has low heavy metal pollution and radioactivity. Building materials products made from this material have significantly lower internal and external radiation indices compared to the existing building materials popular on the market, even surpassing European standards. They fully meet the requirements for A-grade building materials.
Moreover, building gypsum is an energy-efficient product. Producing one ton of gypsum powder can reduce energy consumption by approximately 45% compared to producing one ton of cement, and can cut investment by over 50%.
During the production of gypsum wallboards, there is essentially no discharge of three wastes. In use, gypsum wallboards not only do not produce harmful substances to humans but also utilize the unique properties of gypsum to adjust indoor humidity, preventing termite infestation.
Utilizing gypsum wall panels can increase the effective usable area of buildings. Generally, the wall thickness can be reduced by half, resulting in an approximately 5% increase in effective usable area.
Switching to gypsum wall boards instead of traditional clay bricks will not damage arable land. Currently, our country produces over 700 billion clay bricks annually, destroying approximately 21-28 million acres of farmland. Replacing 10% of clay with gypsum material would reduce land destruction by an additional 20,000-30,000 acres each year.
Using gypsum wallboards can save a substantial amount of cement and steel. Compared to brick-and-mortar structures, the adoption of gypsum wallboard framing saves approximately 150 tons of cement and 400 tons of steel per 10,000 square feet of building area.
Modified gypsum lightweight partition walls offer the following advantages:
The wall is crack-free, with no cracks in the masonry.
Gypsum wallboard boasts a low shrinkage coefficient, eliminating the risk of wall cracking, and superior quality compared to cement products.
2. Lightweight
Gypsum lightweight partition walls weigh just one-third of brick walls and one-fifth of concrete walls, effectively reducing the building's self-weight, minimizing economic foundation investment, and facilitating transportation and construction, thereby lowering the overall construction cost.
High strength
Above 4.5-7.0MP compressive strength, with tenon anchor connections at wallboard junctions, the overall load-bearing capacity exceeds that of common brick masonry.
4. Suspended Load Capacity
The single-point suspension capacity exceeds 1000 Newtons, making it safe and convenient to hang shelves, cabinets, overhead water tanks, and flat radiators from it.
5. Increased Usage Area, Higher Occupancy Rate for Owners
Gypsum wall panels can increase usable space. Calculations show that a 100 sq. ft. room using 90mm wall panels can gain an additional 5 sq. ft. of usable space compared to using 240mm solid clay bricks.
6. Excellent soundproofing performance
Gypsum is inherently an excellent building material with both soundproofing and sound-absorbing properties, capable of blocking 36-42 decibels of noise.
Fire resistance performance is still good.
Gypsum is non-combustible, offering excellent fire-retardant properties and is an ideal fire-resistant material. It does not produce toxic gases and poses no risk of wall cracking during a fire.
8. Excellent thermal insulation properties highlighted
Gypsum wallboard boasts a thermal conductivity rate of 0.12 W/mK, just one-tenth that of concrete, significantly reducing the need for air conditioning. A 9cm thick gypsum wallboard is equivalent to a 24cm brick wall, meeting national standard requirements without insulation material.
9. Excellent Seismic Performance
Gypsum lightweight partition boards are precisely aligned during installation with male and female tenons. The two boards are both interconnected as a single unit and offer shock-absorbing properties. They feature a low modulus of elasticity, allowing for rapid absorption of impact energy, and possess excellent seismic resistance.
10. Easy construction, increased efficiency and reduced costs
Factory prefabricated, on-site assembly, fast construction speed, high labor efficiency; on-site construction requires no reinforcement, no structural columns, no lintel for doors and windows, no hoisting equipment, no framing, minimal hardware and support components, no need for plastering, avoids wet work, less construction waste, simple operation, saves labor costs, reduces auxiliary expenses.
Gypsum wall panels are钉able, sawable, planable, drillable, and repairable, making them convenient for pre-burying water and electrical pipelines, as well as for door and window installation and joint treatment. They are very easy to process. No need for painting, lightweight wall panels can reduce costs and save time in raw materials, labor, and construction due to the elimination of the need for large amounts of cement mortar for finishing.
Gypsum wall panels feature precise dimensions, smooth surfaces, and accurate tenon and mortise fittings, allowing construction workers to operate without professional training or specialized equipment, significantly reducing costs.
Wangshi Building Materials Co., Ltd. in Xi'an produces modified gypsum lightweight partition boards, widely used in interior and exterior partition projects. These boards serve as interior and exterior walls, roof panels, and more in over 5,000 major domestic and international construction projects. Easy to install, with grooves for better flatness, they can be directly applied with joint compound on finished walls without the need for plastering, offering a moderate price.
