1. Easy assembly and disassembly
It is easy and fast to operate with a snap connection; the surface of the template is smooth and clean, it is automatically demoulded, no cleaning and maintenance, and no mold release agent is needed. The surface of the template after use is not sticky with cement, and the template does not need to be cleaned; under the same workload, the construction efficiency Comparable steel formwork increased by 40%; compared with bamboo and wood formwork, construction efficiency can be increased by 40%.
2. Easy to install and disassemble
For the same building area, the hollow building formwork takes about 40% less time than the traditional formwork. The thermal expansion coefficient of the hollow energy-saving building template is very different from that of concrete. After the pouring is completed, the concrete will solidify with the temperature change and the template will automatically detach from the poured concrete. It can be easily removed without knocking, and the working time will be greatly saved.
3. Convenient and safe handling
The density of the hollow building formwork is 0.4 grams/cubic centimeter, which is only 1/21 of the steel material, and the weight is light. A worker can easily take a 900 mm x 1800 mm formwork with both hands, which is very convenient to carry. The formwork will not be deformed or absorb water during use, which can greatly improve the construction safety and its damage rate is less than 1‰.
4. Excellent performance and stability
Polypropylene resin is used as the base material, making it more environmentally friendly Polypropylene resin (PP particles) is a crystalline polymer with regular structure. It is light milky white pellets, odorless, non-toxic, and lightweight thermoplastic resin. It has good mechanical properties, good heat resistance, good chemical stability, and acid resistance. , Alkali and organic solvents. Under the temperature condition of -10℃ to 75℃, it will not shrink, swell, crack or deform, and its size is stable.
5. Green and environmental protection
The hollow plastic board adopts modern HDPE and HDPP materials, which is a light weight (hollow structure) and non-toxic. Plastic is used to replace wood, plastic is used to replace steel, and plastic is used to replace bamboo. It can be recycled more than 50 times. It can be recycled and reused without generating harmful waste and toxic gases, reducing the destructiveness of the environment.
6. Strong plasticity
It can be sawed, planed, drilled, nailed, and combined with accessories to form any geometric shape at random to meet the needs of various forms of building components. Because the hollow plastic template uses a special molding process, any color can be achieved by color mixing through the masterbatch, and the surface is smooth and easy to print.
