Equipment requirements

Mixer requirements:

(1) The structure of the agitating slurry must satisfy the uniform mixing, no mixing dead angle in the pot and a more reasonable drainage device;

(2) The collection point of material temperature and the temperature control accuracy of the temperature controller are reliable

(3) Configuration of dust removal and dehumidification device

Extrusion equipment requirements:

(1) achieving good dispersion and infiltration of wood powder, resin, additives, etc.;

(2) has a good mixing function, the single shear force can not be too high;

(3) A precise and sensitive temperature control system;

(4) There is a good exhaust system, dehydration and devolatilization, so that the product has no bubbles;

(5) The material of the plasticized parts of the equipment is well treated, and the screw, barrel and the like have sufficient wear resistance and service life.

Mold requirements:

(1) Wood-plastic special hanger runner design

(2) No dead angle control accurate

(3) Accurate temperature control

4. Plant structure and hydropower installation

(1) The minimum height of the main workshop is 4 meters, the minimum length is 35 meters, and the minimum width is 6 meters; the minimum area of ​​the mixing workshop and warehouse is 12 meters × 6 meters; the minimum planned area of ​​the plant is not less than 1500 square meters.

(2) The equipment must be cooled during the production process, and the cold air tower (30 tons) can be installed on the outdoor circulating pool. The installation area is 16 square meters and its installation height is at least 1 meter, which is connected to the indoor equipment pipeline. The main pipe can be used with 2, 1/2 or 3 steel pipes, which are set according to the water inlet of the pump on the equipment. The drain pipe can be selected from 110mm PVC pressure pipe and the cooling water (cycle) is 5-8 tons/hour.

(3) The drainage ditch under the fixed table shall be opened according to the installation diagram of the production line.

(4) The total installed capacity of production equipment is 300Kw (one production line).

9, waste formula:

1. The basic materials of wood plastic products are as follows:

(1) waste PVC;

(2) The filler is wood flour and calcium carbonate;

(3) Auxiliaries are stabilizers and foaming agents

2. Cost accounting: cost per ton of building formwork: 5,500 yuan / ton (waste).

We calculate the cost according to the output of 6 tons per day on a production line (the actual manufacturers are more than two production lines, the cost is lower). The data is as follows:

A——The cost of waste PVC building formwork formula is 5,500 yuan / ton

B——Power consumption per ton of product: 685 yuan / ton

C——Integrated management fee per ton of product: 100 yuan/ton

Note:

B=(The power consumption of the mixer is 1000 degrees per day + the power consumption of the extruder is 3800 degrees per day) ÷ 6 tons per day × industrial electricity

According to 0.8 yuan / degree = 548 yuan / kWh

C= The daily comprehensive management fee for a production line is 600 yuan / day ÷ 6 tons / day = 100 yuan / ton

Building template cost per ton = A + B + C = 6285 yuan / ton

3, ex-factory price: 9375 yuan / ton

According to the ex-factory price of Huangshi Hongtai Board in August 2011, the price of three or six feet (1830mm × 915mm × 15mm) is 150 yuan / piece, and the weight is 16 kg / piece, that is, the price per ton is:

150 yuan / Zhang Wei 16 kg / Zhang × 1000 kg = 9375 yuan / ton

4. Profit per ton of product: 3,875 yuan / ton (gross)

9375 yuan / ton (ex-factory price) -5500 yuan / ton (construction template per ton formula cost) = 3875 yuan / ton (gross)

3875 yuan / ton (gross) - 1000 yuan / ton (manual + electricity fee) = 2875 yuan (net profit)

5. Annual profit of a production line: 4.5 million yuan

Annual profit = annual output × profit per ton = 6 tons / day × 300 days × 2,500 yuan / ton (profit per ton) = 4.5 million yuan

※ The raw material price per ton of product is 5,500 yuan / ton, the proportion is 0.65, 36 ft (1830 long × 915 wide × 12 thick) 16 kg, and the raw material cost is 88 yuan / piece. The market price is 150 yuan / piece.
