Description

Technical Field

[0001] The invention belongs to the technical field of nacelle covers, and in particular relates to an application process of a reusable material on a nacelle cover. Background Art

[0002] The nacelle cover usually refers to the protective shell covering the outside of the nacelle of the wind turbine mechanical equipment. Its main function is to protect all components in the nacelle from the external environment and ensure the normal operation and service life of the equipment.

[0003] The design of the nacelle also needs to consider aerodynamic performance to minimize wind resistance and improve the fuel economy and performance of the equipment. Especially on high-speed equipment, the shape, size and surface parameters of the nacelle will have a significant impact on the basic aerodynamic performance.

[0004] Early cabin covers were mostly made of traditional materials such as inorganic glass and steel. These materials have basic wind-blocking and protective functions, but have disadvantages such as heavy weight, fragility, and poor process performance.

[0005] With the development of material science, composite materials have gradually become the mainstream materials for cabin covers. Common composite materials include fiberglass, carbon fiber composites, glass fiber composites, etc. These materials have excellent properties such as light weight, high strength, chemical corrosion resistance, electrical insulation, and microwave transparency, which can meet the high requirements of cabin covers for material properties.

[0006] In the above-mentioned material problem, the present application provides a process for applying a reusable material to a cabin cover. Summary of the invention

[0007] To achieve the above object, the technical solution of the present invention is as follows: A process for applying reusable materials to the nacelle cover, Paul follows the following steps; Step 1: Debug the metal die; fix the metal die to the press, connect the upper and lower metal die to the temperature controller, set the temperature to 150~180℃, and adjust the press parameters, including pressing speed, rising speed, etc. Step 2: Start the press; separate the upper metal mold into a positioning cover, put the pre-cut plastic plate into the lower metal mold, brush a layer of unsaturated resin, and put a layer of 300g / m2 alkali-free chopped felt + paper honeycomb; Step 3: Filling with glue: Use a polyurethane glue filling unit to spray polyurethane into the paper honeycomb, pay attention to controlling the amount, and then cover it with a layer of 300g / m2 alkali-free chopped felt; Step 4: Manually operate the unit; the personnel start the press after reaching the safety position, press the upper metal mold down, and leave the cover for about 8 minutes to ensure that the resin and polyurethane are completely cured; Step 5: Demolding and processing the product; after the product is removed, use a utility knife to cut off the burrs and apply the inner surface gel coat; Furthermore, a polyurethane glue pouring unit, a press, a metal-matching mold and a mold temperature controller were used in the process of debugging the metal-matching mold.

[0008] Furthermore, the thickness of the cut plastic plate is 1mm, the color is RAL7035, and the material is PA6, PC, ABS, etc.; this material is suitable for most cabin covers.

[0009] Furthermore, the size of the paper honeycomb can be selected within the range of 10 mm, 15 mm and 20 mm.

[0010] Furthermore, polyurethane uses two groups of black materials and white materials. The white material uses polyether polyol, while the black material uses dicyanate.

[0011] Furthermore, when demolding, the operator uses an external release agent.

[0012] The beneficial effects of the present invention are: Compared with the prior art, the present invention improves the production efficiency of products by debugging the metal matching mold. At the same time, the metal matching mold is covered with metal incisions and exhaust holes. The burrs of the products can be exempted from cutting after demolding. The 300g / m2 alkali-free chopped felt + paper honeycomb solution is adopted to cancel the ordinary mesh cloth. On the one hand, the surface quality can be improved. On the other hand, the metal incisions provided in the metal matching mold can facilitate the cutting of burrs. There is no cutting dust in the whole production process, and there is no need to cut burrs. At the same time, the size and loss of the materials can be controlled. Intelligent production can be used for batch production first to reduce labor loss.

[0013] The present invention reduces the generation of solid waste during the production of cabin covers and fairings by optimizing the product material structure. At the same time, the solid waste can be recycled and reused, thereby reducing the manufacturing cost during the product production process and improving the company's competitiveness in the industry.
