Feasibility report of pp hollow grid construction boardHollow plastic building template equipment
ONE. Characteristics and advantages of hollow plastic building templates
1. Reduce costs. Hollow building formwork turnover of more than 50 times
2. Energy saving and environmental protection. No harmful gas is released from the hollow building template, and the template can be repeatedly processed and regenerated after being scrapped.
3. Smooth and smooth. The surface of the hollow building template is smooth and flat, and the demoulding effect exceeds the technical requirements of the clean water template, eliminating the second plastering.
4. Stable weather resistance. The hollow building template is resistant to aging, acid and alkali, corrosion, and has a small expansion coefficient.
5. Superior performance. The hollow building template has high strength, good toughness, no cracking and no layering.
6. Light and easy to install. Lightweight and easy to install, each piece weighs 14-15KG, which is only half of the wooden formwork, saving time and effort for workers.
7. High price recycling. After the template is scrapped, the company can recycle it at a high price.
8. Easy to store. The hollow building template is cold-resistant, high-temperature resistant, insect-resistant, and does not require special treatment for storage.
9. Easy demoulding. No need to brush the mold release agent for demoulding.
10. Strong variability. The template can be arbitrarily cut, cut and drilled.

V. Comparison of the use cost of hollow plastic building template and wooden template (bamboo template) in 3 buildings
Hollow composite plastic template wood template (bamboo template)
The cost of the first building: 7500x100 yuan / = 750000 yuan above ground: 7500x30 yuan / = 225000 yuan.
Above ground: At least 3 batches of template are needed for 30 floors, above ground cost: 225000x3 = 675000 yuan
Underground: 1000x3x20 yuan / = 60,000 yuan.
Total: 675000 + 60000 = 735000 yuan.
The cost of the second building: 1. Same house type, 100% utilization rate, cost: 0;
2. Take the different apartment types as an example: the utilization rate is 70%, and the cost is: 7500x30% x25 = 56250 yuan (the price for the old one is 25 yuan /) The same as the cost of the first building template, 735000 yuan
Cost of the third building: Same as the cost of the second building. It's also 735,000 yuan
The total cost of 3 buildings is 750000 + 56250 + 56250 = 862500 yuan
Recycling: 7500x30 yuan / = 225000 yuan (recycling: 50 yuan / sheet)
Then the actual cost of use is: 862500-225000 = 637500 yuan. 735000 × 3 = 220500 yuan.
six. Production equipment for hollow plastic building templates

14. Electrical Control System
It can be seen from the comparison that the use of hollow composite plastic formwork is about 35% of the cost of bamboo and wood formwork, which has good economic value and saves construction costs.
Architectural formwork is divided into large board (1220 * 2440) and small board (915 * 1830). The thickness is between 12-18, represented by the thickness of 14. Such a formwork is often used. Let's take this as an example and talk about his costs and profits in an easy-to-understand manner. I believe this is the voice of all investors who want to invest.
The weight of one square is about 8 kg, and the price of PP raw materials is currently about 6500-7000 yuan / ton on the market. The price of this raw material will fluctuate, and the price will be different in different periods of the region. Please pay attention to the price of local materials, so as to more accurately estimate the profit margin.
One large board (1.22 * 2.44) 2.97 square meters * 8 kg / square ----- 23.76 kg * (6500-7000) ------ 154-161 yuan / sheet
A small board (915 * 1830) 1.67 square meters * 8 --------- 13.4 kg * (6500-7000) ----------------- 86-91 Yuan / Zhang
The above is the raw material cost of a large board and a small board. The current market price is about 80 yuan / square. In other words, the big board is 237, the small board is 107, and the profit margin is still very attractive.
Some people will ask about the output, OK, a production line can produce about 600-800 large boards 24 hours a day, and if operated properly, it can be up to about 900 sheets. Then, calculate how much you can earn in a day. Hey, that's quite objective. By the way, I also mentioned that the cost of raw materials was high, and one ton of product would add 300-500 yuan of depreciation for hydropower equipment. It is such an exaggeration, which is still quite objective.
The equipment investment threshold is relatively high. Because the future is bright, if you have this strength, please take action to squeeze out and change the world and squeeze out a better life.
