1. Introduction and market prospects of PVC wood-plastic building template project
(1) Product background
Building template is an important tool for concrete structure engineering construction. In cast-in-place concrete structure engineering, formwork engineering generally accounts for 20%-30% of the concrete structure engineering cost, 30%-40% of the engineering labor cost, and about 50% of the construction period. Formwork technology directly affects the quality, cost and benefit of project construction, so it is an important content to promote the progress of my country's construction technology.
At present, the main formwork for construction in my country is wood formwork. According to the statistics in 2009, the market size of wood plywood formwork was 300 million square meters, its annual output was 77.3 million square meters, and the market size of bamboo plywood formwork was 122 million square meters. The annual output is 31.4 million square meters. At present, China's total timber demand is more than 100 million cubic meters, while the market supply is only more than 60 million cubic meters, with a gap of about 40 million cubic meters. The formwork alone requires more than 3 million cubic meters of wood. my country's timber resources are scarce, and importing timber will cost a lot of foreign exchange. At present, there are two ways to solve this problem: on the one hand, it is to encourage the import of wood; on the other hand, it is to seek wood substitutes through the research and development of new materials. Wood-plastic template has become the preferred substitute. Many foreign countries such as the United States and Canada have invested heavily in the development of wood-plastic projects.
The production scale of my country's construction formwork industry will maintain a growth rate of about 10% in 2010; the average annual growth rate of production scale of my country's construction formwork industry will be around 15% from 2011 to 2012; by the end of 2012, the output of my country's construction formwork industry will reach 220 million About square meters. The average annual total demand for construction formwork panels is conservatively calculated to be more than 200 billion yuan, and it is increasing at an average annual rate of 9-12%. In the next 2-3 years, wood-plastic building templates will occupy 30%-50% of the market share, and the output value will reach about 60-100 billion. The market prospect is very broad.
(2) Performance comparison of common building templates
1. The wooden formwork was the first to be used. Because a large amount of wood is consumed, and the disassembly formwork is easy to split, the loss rate is relatively high, and the general turnover is 4-6 times. For our country where forest resources are not abundant, we should seek alternative products.
2. Steel formwork: The advantage is that it can save a lot of wood, but it also has many unsatisfactory points:
(1) The cost is high, the average price is 280 yuan/square meter, which is much higher than the price of wood-plastic template;
(2) Bulky, inconvenient construction and lifting, and difficult to disassemble. The area of a single template is not large, and there are many splicing blocks in use, which is time-consuming and laborious;
(3) The steel formwork has a strong affinity with cement. When the formwork is removed, it is easy to peel off the surface of cement products such as columns or beams, which affects the quality;
(4) The steel template is easy to rust.
3. Advantages of PVC wood plastic building template:
①Can save a lot of wood;
②It has advantages in convenience and safety of construction;
③WPC does not require maintenance and can be recycled, so production costs can be greatly reduced, and many key problems in engineering can be solved.
(Three) PVC wood plastic template performance and advantages
Wood plastic formwork processing WPC formwork application
PVC wood-plastic template is a new type of environmental protection material compounded by plant fiber and PVC resin.
The annual output of plastic products in my country exceeds 40 million tons. Ranked second in the world, about 13.84 million tons of waste plastics are produced every year. The output of domestic agricultural plant fiber is tens of millions of tons, wood materials are more than 1 million tons, and other natural fibers are also 5-10 million tons, which provides a rich raw material foundation for the development of my country's PVC wood-plastic template.
1. Features of PVC wood-plastic composite materials:
(1) There are wide sources of materials and low value.
(2) Wood-plastic products are artificial overall synthetic products, and the product process and formula can be adjusted randomly according to the requirements of use, so as to produce materials with different properties and shapes, and the utilization rate of its profile is close to 100%.
(3) The wood/plastic base material of PVC wood plastic material and its commonly used additives are environmentally safe, non-toxic and harmless, and there will be no side effects during the production and processing process, so it does not pose any harm to the human body and the environment.
(4) The maintenance cost is extremely low, and the product life span is several times that of ordinary natural wood,
(5) Scrap products and recycled waste products of PVC wood plastic materials can be 100% recycled, and will not affect product performance.
2. Advantages of PVC wood plastic building template
(1) There are wide sources of raw materials, low overall cost, and certain competitiveness in the market;
(2) The basic performance is equivalent to that of wood, which can be sawn, nailed, and corrosion-resistant, and its products have better durability than wooden and bamboo building templates;
(3) The product assembly is flexible and can be changed according to the specific requirements of the market and users;
(4) High reuse rate and recyclable;
(5) Not afraid of insect bites, acid and alkali resistance, aging resistance, not easy to absorb water, and easy to peel off from concrete.

5. Feasibility analysis of PVC wood-plastic building template project
(1) Basic composition of raw material formula and raw material cost analysis:
1. Analysis of basic composition of raw material formula:
Name Percentage Reference Price
PVC resin powder 10% 6300 yuan/ton
Wood flour 5% 700 yuan/ton
CaCO3 25% 900 yuan/ton
Functional additives 10% 15,000 yuan/ton
Recycled material 50% 3500 yuan/ton
Total raw material cost: 4140 yuan/ton
2. Analysis of processing cost: electricity fee + labor + water consumption + other = about 600 yuan/ton
3. Total cost: 4140 yuan/ton+600 yuan/ton=4740 yuan/ton=4.74 yuan/kg
4. The cost of a single board (take 1830×915×15mm board as an example, weight 16.5 kg): 4.74 yuan/Kg×16.5Kg/piece=78.21 yuan/piece
(2) According to the profitability analysis of a production line, the number of employees and the tax paid to the state:
1. Output value: calculated at 500 sheets/day
Annual output: calculated on the basis of 300 days of annual production, an annual output of 150,000 sheets
Annual production value: 150000×120 yuan/sheet = 18000000 yuan (calculated based on the current market price of 120 yuan/sheet)
2. Annual profit: 150,000 sheets × (120 yuan / sheet-78.21 yuan / sheet) = 6,268,500 yuan
3. Number of labors: 4 workers are employed per shift, and production is divided into 2 shifts every day, totaling 8 workers
(3) According to the normal business scale of the company, five production lines are needed to meet the market demand of a county. If the sales channels radiate to surrounding counties and cities, the business scale of the company will need to be expanded accordingly. Calculated according to the company's operating scale of 5 production lines:
1. Annual production value: 18 million yuan × 5 production lines = 90 million yuan
2. Annual profit: 6,268,500 yuan × 5 production lines = 3,1342,500 yuan
3. Number of employees: a total of 52 jobs can be provided for the society
Production workers: 8 people × 5 production lines = 40 people
