The hollow plastic formwork for construction uses polypropylene resin as the base material, and chemical additives such as curing, strengthening, weather resistance, aging resistance, flame retardants, etc. are added. It has good mechanical properties, good heat resistance, good chemical stability and acid resistance.
The hollow plastic formwork is non-toxic and harmless without the need to worry about using it. No peculiar smell, no poison, no pollution, no toxic or harmful substances during use; resistance to cold and heat, no shrinkage, small expansion coefficient, moisture, no cracks, no deformation, dimensional stability at -10℃ to 75℃; the hollow structure of plastic formwork for construction has high strength, strong impact resistance, and does not break when dropped vertically from a high altitude.
The hollow plastic formwork has no water absorption, no mold, no rot, no rust, and low maintenance cost. The hollow plastic formwork for construction is used in high-rise buildings and super high-rise buildings, and is called plastic beam formwork, plastic upper mold and plastic wall formwork.
1. The hollow plastic formwork is firmly welded during use. When there is no leakage, the surface is smooth and flat, the construction quality is improved, the disassembly and assembly process is simple, so there is no need to use a release agent, and the molding surface does not require adhesion. The concrete plaster is applied to reduce the cost of labor and 50% of excipients.
2. After the construction of the project, the plastic formwork for construction does not need to be deliberately maintained and can be cleaned with clean water, the process is very simple.
