It is recommended that the length of the extension should not exceed 5 meters. Among all the sunshade products, the canopy is a good partner for the sunroom. Outside sunshade electric double-track ceiling curtain: electric double-rail folding ceiling curtain is a sunshade system that can be retracted and put on the top or oblique side glass window frame of indoor lighting roof, that is, double-rail translation system. If the daylighting of the balcony at home is on the middle side, it is recommended not to use full shading curtains, but to use semi-shading curtains, so it is appropriate to choose whether shading is needed or not. The color of the space tends to be simple and pure. Plus the silver-gray sunshade looks like a perfect match.
External shading mainly refers to covering the sunshade net on the outside of the greenhouse, which directly shields the solar radiation outside the greenhouse, which can effectively reduce the temperature in the greenhouse. At the same time, the external shading system can be active. with the continuous development of science and technology, there are more and more kinds of greenhouses, and greenhouses for cultivating all kinds of plants and organisms are also built, and a variety of methods are used to control the temperature in the heat preservation work. every week, when irrigation is carried out, the end of each drip irrigation pipeline is opened in turn, and the fine particles accumulated at the end of the eyedropper are flushed out with high-pressure water. The pipeline must be opened one by one to ensure sufficient pressure,
The components that can be used to lighten the weight of the car are: headrest, dashboard, door lining, steering wheel, tire cover, luggage compartment lining, seat backrest decoration, sunshade, bumper core, air conditioning barrier, carpet support material, roof, side guard, door inner panel energy absorption protection pad, buffer pad, muffler plug-in, rear engine compartment, engine guard.
Of course, the cooling work of the greenhouse in summer can not rely entirely on the greenhouse insulation quilt, but also should take some other measures accordingly. Can cooperate with enhanced ventilation to cool down, but it should be noted that it is best to set up a wind shield in the tuyere to avoid the cold wind blowing directly on vegetable and fruit noodles; you can also use a sunshade net to cool down, and the shading rate of the shading net can be selected according to your needs. The advantage of shading net is that it can not only prevent sunburn vegetables, but also allow part of the light to illuminate the interior of the greenhouse, ensuring the photosynthesis of vegetable leaves; you can also take spray cooling methods.
When the temperature decreases in winter, choose the plastic film with good transparency and strong insulation to cover the windows, doors and ceilings. When the outdoor temperature drops below zero, the windows and doors are covered with a layer of plastic film, and the ground is padded with rice chaff, rice straw or heat sources in the shed. However, attention should be paid to ventilation to prevent the occurrence of diseases. With the increase or decrease of temperature in spring and autumn, the plastic film should be opened or covered appropriately in time. Mainly do a good job of cooling in summer. When it is too hot, open all the windows and vents, turn on the electric fan to cool down when possible, and hang the sunshade net where the sun shines.
2) the intelligent sunshade control system uses the brightness sensor to control the sunshade motor. In the automatic mode, the sunshade system can automatically adjust the opening and rotation angle of the sunshade according to the exposure angle of the sun, the intensity of the light, the size of the wind, the quality of the weather and other factors to judge whether to close or not. The system protects buildings and their users from direct sunlight. Summer can block sunlight, block light, avoid excessive heat passing through windows and reduce indoor temperature; in winter, sunlight can be used to heat indoor, improve indoor thermal comfort, adjust the lighting demand of indoor space, and achieve the purpose of environmental protection and saving air-conditioning operation cost.
This category mainly refers to the use of manually adjustable (including manual adjustment and manual control of electric adjustment) shading facilities (sunshade panels, blinds, curtains, etc.) or selection of transparent materials (such as photoelectric glass, sunshade type Low-e coated glass, etc.) to adjust the angle and length of shade blades according to sunshine angle, sunshine time and environmental conditions in different areas and seasons in order to control light. Keep the strong light outside in summer to reduce the cooling energy consumption, and the warm sunshine in winter into the indoor to reduce the heating load.
Greenhouse heat preservation should be done a good shading work, greenhouse heat preservation in the hot season greenhouse vegetable cultivation should adopt shading cover measures, commonly used shading equipment is sunshade, shading should be selected according to plant species. Short plants choose black shading net to choose gray shading in autumn and winter vegetable cultivation. Because the gray shading can prevent the growth of insects, if the seeds or film delay the cultivation of plants need to use the network. On August 7, when the weather is hot, it can be used in the sunshade net, which is relatively weak in the cold season, does not need lighting or no curtain, and does not shade in the heavy rain season. The heat preservation time of the net greenhouse is not long, and the plants are covered on the surface, especially the dark shade opens the daylighting. When growing mushroom crops, greenhouse heat preservation will not cause fungal crop infection, and the products can be recycled.
At present, spray-free plastics have been successfully used in side skirts, central control panels, DVD panels, glove boxes, sunshades, instrument panels and other automotive parts in the automotive field. Bioplastics bioplastics are produced by using original plants as raw materials, such as sugar cane and corn, under the action of microorganisms. Commonly used plastics generally use petroleum products, and there are often small molecular harmful substances that do not fully react, while bioplastics, due to the use of low-toxic and low-harm renewable raw materials, greatly reduce the VOCs volatilization in the car after turning it into automobile interior parts. In addition, this bioplastic can be used for subsequent use, and is a more environmentally friendly type of plastic.
