2015 National implementation of building energy efficiency and structural integration, which is crucial to use the building's exterior insulation board. FS composite insulation board production line is I am referring to Germany and other advanced countries of advanced technology and experience, by trial and the successful development of new products. Exterior is a major innovation to achieve industrial production of insulation board. Is 2015 and the structure of the building energy efficiency efforts to promote the integration of the provinces wall insulation board products. But invest in a FS composite insulation board production line how much money needs to invest? Require much space it? How the economic benefits? I got you a detailed description of these questions; first the equipment components; automatic mixing system, automatic plate making machine, automatic cutting saws, automatic palletizing systems and group drills five parts. Followed confinements conditions and benefit analysis: First, the confinements conditions ① site: 500 square meters production plant material library 300 meters, finished products (shed) / 1000 m. ② water: 14m3 / d. ③ Electricity: capacity 40kw. ④ Staff: 8-12 who need workers. Second, the cost accounting: Cost and Benefit Analysis (by 40 ~ 60mm thick design, saving 65% basis) (1) raw material price of ordinary Portland cement: 0.5 yuan quartz sand: 0.4 yuan admixture: 1.3 yuan Mesh: 1.5 yuan / square meters insulation boards 15-18 yuan / raw material cost per square meter 18-21.7 yuan / m (2) Utilities: water and electricity prices by around average for 0.2 yuan / m (3) Salary: 500,000 ten thousand square meters of production workers need eight people, according to the average price of 1 yuan / square meters (4) Administrative expenses: Staff need four people, the cost is 0.7 yuan / m (5) Selling expenses: according to 2 yuan per square meter Computing (6) Depreciation: Calculated by 1 yuan per square meter (7) factory rents: calculation by 0.8 yuan per square meter per square meter costs 25-27.4 yuan / square meters according to an annual output of 500,000 square meters calculation, 40 ~. 60mm, for example, around 55 to 68 yuan price / square meters, the annual output value of 500 000 m × (55 ~ 68 million) / m = 27.5 million - 34 million yuan of the total cost of 50 million square meters × (21 ~ 25) yuan / = 10.5 million - 12.5 million yuan in total profits = (2750 - 3400) million - (1050 to 1250) million = 1200 to 21.5 million yuan (8) years of tax = (2750 - 3400) million × 6% = 165 to 204 million per year after tax profit of about 1500 to 19.5 million yuan. So much of the profits earned by the need to invest much money, plant, labor, materials, equipment and installation as well as supporting utilities 200-3000000 enough.
