Temporary shading is the installation of lightweight curtains, plastic blinds or pendants at the window, while sexual shading is the installation of sunshades in various forms at the window. The facilities of sexual sunshade system can be divided into active form and fixed form according to whether the components can be disassembled and moved. In recent years, the active sunshade system is widely used in buildings in our country, and the angle of the sunshade can be adjusted freely according to the annual seasonal change or the all-day sunshine change. Because of the strong flexibility of this facility, it can also be easily removed in order to get sunshine and avoid blocking the sun in the cold season. Today, with the rapid development of science and technology, there are all kinds of heat reflection glass, such as sunlight control film, coated glass, low emissivity film glass and so on.

Thank you for watching, please reprint and indicate the source of the wide source greenhouse. Thank you for your cooperation. The multi-span greenhouse greenhouse is an upgrade style of the single arch greenhouse, due to the ultra-high utilization rate of the multi-span greenhouse greenhouse and the level of mechanization automation. Secondly, from the control system of the multi-span greenhouse greenhouse, electric sunshade, electric film, window opening, ventilation, electric heat preservation and electric fan water curtain have been realized. The control ability of the greenhouse is more stable and reasonable, the work efficiency is higher, do not need too much manual operation, only need to press the switch of the distribution cabinet, looking at the production in some backward areas ten years ago or even now. This is a great progress for facility agriculture in our country. Secondly, the interior of our multi-span greenhouse can be equipped with mechanized automatic fertilizer spraying machine, automatic seeder and even Internet of things control is now a very common system.

The importance of glass greenhouse. Temperature is the basic condition to ensure the normal growth of crops. Greenhouse is a thermal insulation agricultural facility for the normal and rapid growth of crops. Heat preservation is an important work in greenhouse agricultural production, so suitable covering materials must be selected. Generally speaking, glass greenhouse is better than glass greenhouse, glass greenhouse can play a decorative role in appearance, and the aging and damage problems of glass greenhouse can be relatively small compared with plastic greenhouse; in terms of performance, due to the complexity of the environment, glass greenhouse can resist various loads (wind load, snow load, etc.). Aluminum alloy (or stainless steel) + plexiglass, ordinary glass, low-cost bamboo ponds and plastic films with beautiful and durable, windproof, rainproof, sunscreen, heat preservation effect and cost, can also be equipped with sunshade and sprinkler system. Plants usually need plenty of light and better glass. Of course, the one-time investment cost of plastics is lower, but the later maintenance cost is also higher, and plastics are easy to age.

two。 Sunshade. The membrane structure Suzhou parking shed adopts polycarbonate material with high impact resistance, and its strength is about 200 times that of glass. The raw materials are imported from Germany and processed in China. Through the double-sided co-extrusion process, the anti-ultraviolet material (UV) is added, which can effectively block more than 98% of the ultraviolet rays, protect the car surface paint, effectively control the continuous rise of the interior temperature, and in direct sunlight. The temperature in the car can reach more than 60 ℃ and can be effectively reduced to about 40 ℃ after installation. At the same time, it also has flame retardant effect, and can be used normally for more than 30 years in the environment of-30 ℃ to 60 ℃ (137 ℃ thermal deformation). The downcomer is made of high-strength aluminum alloy and has a unique user-friendly design to avoid the second pollution to the car and you when the roof water falls to the ground. The structure is reasonable and easy to clean, and it is convenient for the Suzhou parking shed with membrane structure to remove dirt from the pipe.

Although the dashboard is not a full LCD screen, it is equipped with a large area head-up display system, and the left side of the semi-suspended structure of the multimedia screen is connected with the dashboard sunshade. Although the steering wheel has a four-spoke structure, it has a strong sense of science and technology, and the most added point is, of course, the push-button electronic shift mechanism, which directly enhances the luxury of the new Sonata. The power system may be the biggest difference between the domestic version and the overseas version. The Korean version will use the new naturally aspirated engine, while the domestic version may mainly drive turbocharged power.

2. Thermal commonality first of all, it refers to the connection between different kinds of metals or between metals and non-metals by heating metals and manipulating the principle of thermal expansion or thermal melting. For example: aluminum sheet for copper core of computer radiator, embedded welding of horn net, composite of steel-plastic pipe, sealing of aluminum foil (toothpaste skin), motor rotor, electric heating pipe sealing and so on. 4. Automotive supplies industry: the automotive supplies industry continues to develop new cars and adopt different car interior accessories, the use of high packaging equipment technology is mainly used for car sunshade panels, car door panels, car airbags, car floor mats, car anti-skid mats, automobile leather pressing, and so on.

The overhead ventilated roof is widely used in hot summer and cold winter areas in China, especially in the hot and rainy summer, which shows its superiority. The principle of the ventilated roof is to set up a ventilation room layer on the roof. On the one hand, the outer layer of the ventilation room layer is used to block the sun, such as a closed or ventilated air room layer, and the sunshade intercepts the sun directly shining on the roof. The radiant heat makes the roof heat transfer twice, avoiding the direct action of solar radiant heat on the enclosure structure, on the other hand, using the effect of wind pressure and hot pressure, especially natural ventilation, the solar radiant heat absorbed by the upper and lower surfaces of the sunshade in contact with the air is transferred to the air with the wind. The greater the wind speed, the more heat the roof takes away, and the better the thermal insulation effect is, the greater the thermal insulation capacity of the roof is. So as to reduce the effect of outdoor heat on the inner surface.

According to the management of medium-and long-term weather forecast, in case of continuous low temperature, the temperature of the mushroom house / shed should be kept above 8 ℃ ~ 10 ℃. The main measures for heat preservation and warming include: thickening the roof cover at night; hanging blankets on doors; closing doors and windows for heat preservation in the morning and evening; opening doors and windows around noon in sunny days; opening only leeward vents for short-term ventilation in rainy and snowy weather; in cold or windy weather, close doors, windows and vents to prevent cold air from attacking. When the weather is fine, open the cover to increase the temperature of the light, when the light is strong, it is best to set up a sunshade net under the greenhouse film and above the bacterial stick to protect the light and heat. If there are heating facilities such as hot air stove, the temperature of the mushroom room / shed can be increased by heating, but attention should be paid to prevent the smoke from being discharged into the shed and cause poisoning. In addition, the ditch cleaning and drainage of the mushroom shed should also be done to reduce the humidity in the greenhouse in the rainy season and improve the mushroom quality.
