Feasibility report of hollow plastic building formwork equipment
Feasibility report of hollow plastic building formwork equipmentThe PP plastic hollow building template production line can range from 8-18mm in sheet thickness, and the sheet width can be customized to 915-1220mm according to customer requirements. Its products have smooth surface, small dimensional error, and have many advantages such as nailability, planing, corrosion resistance, and strong flame retardancy.
The PP plastic hollow building template production line consists of a single-screw extruder or twin-screw extruder, hydraulic screen changer, metering pump mold, sizing plate, primary tractor, cooling bracket, secondary tractor, cross-cutting machine, automatic drop Plate manipulator composition.
1. Features and advantages of hollow plastic building formwork
lower the cost. Turnover of hollow building formwork has reached more than 50 times
Energy saving and environmental protection. The hollow building template has no harmful gas release, and the template can be repeatedly processed and regenerated after it is scrapped.
Smooth and neat. The surface of the hollow building template is smooth and flat, and the demoulding effect exceeds the technical requirements of the clear water template, eliminating the need for secondary plastering.
Stable and weatherable. The hollow building template is anti-aging, acid and alkali resistant, corrosion resistant, and has a small expansion coefficient.
Superior performance. The hollow building template has high strength, good toughness, no cracking, no delamination.
Lightweight and easy to install. Light weight and easy to install, each weighs 14-15KG, which is only one-half of the wooden template, saving time and effort for workers.
Recycling at a high price. After the template is scrapped, the company can recycle it at a high price.
Convenient storage. The hollow building template is cold-resistant, high-temperature resistant, and insect-proof, and no special treatment is required for storage.
Easy demoulding. The mold release does not need to brush the mold release agent, and it is easy to release the mold.
Strong variability. The template can be cut, cut, and drilled arbitrarily.

V. Comparison of the use cost of hollow plastic construction formwork and wood formwork (bamboo and wood formwork) in 3 buildings
Hollow composite plastic template
Wood template (bamboo and wood template)
Cost of the first building:
7500㎡x100yuan/㎡=750000yuan
Above ground: 7500㎡x30yuan/㎡=225000yuan.
Above ground: At least 3 batches of templates are required for a 30-story building, and the above ground cost is: 225000x3=675000 yuan
Underground: 1000㎡x3x20 yuan/㎡=60,000 yuan.
Total: 675000+60000=735000 yuan.
Cost of the second building:
1. The apartment type is the same, the utilization rate is 100%, and the cost is: 0;
2. Take the different types of houses as an example: the utilization rate is 70%, and the cost is: 7500㎡x30%x25=56250 yuan (the old trade-in price is 25 yuan/㎡)
Same cost as the first building template, 735,000 yuan
Cost of the third building:
Same as the cost of the second building.
The same cost 735,000 yuan
Total cost of 3 buildings
750000+56250+56250=862500 yuan
Recycling: 7500㎡x30 yuan/㎡=225000 yuan (recycling: 50 yuan/sheet)
The actual use cost is: 862500-225000=637500 yuan.
735000×3=220500 yuan.
