The shading design should be based on the climate characteristics of the area, the use requirements of the room and the orientation of the window. The effect of sunshade facilities on shielding solar radiation heat not only depends on the shading form, but also depends on the structure, installation location, material and color of sunshade facilities. The shading device can be set to permanent or temporary. Permanent sunshade devices include setting various forms of sunshade panels in the window; temporary sunshade devices include lightweight curtains and various metal or plastic blinds in the window. Permanent shading facilities can be divided into two types: fixed and movable. The movable sunshade facility can adjust the angle of the sunshade according to the change of season, the time of day and the gloom of the sky. Shading measures can also use a variety of heat reflection glass and coated glass, sunlight control film, low emissivity film glass and so on.
A: the advantage of car sunshade is to block the sun, to a certain extent, to reduce the burning heat inside the car, to prevent leather seats and dashboards from being exposed to ultraviolet light, and to increase privacy, and it is not clear to see inside and outside the car. can increase safety factors.
Types include fuel tank, bumper, sunshade seat, door handle, steering wheel, dashboard and so on. Today, abs recycled plastics in the molding processing of plastic products also have a small number of failures, so that its use is bound, the mechanical strength of general plastics may as well be metal. The shrinkage of plastic is higher during molding. The sensitivity of plastic to temperature is much greater than that of metal or other non-metallic data, and the temperature boundary of plastic is much narrower than that of other data. If the plastic is loaded for a long time, even if the temperature is not high, its shape will have “creep”. The gradual plastic activity of plastic parts is unmalleable, resulting in the loss of dimensional accuracy of plastic parts.
So we should adopt the form of deep ploughing. Only in this way can we compare the photosynthesis between plants. It can do a good job of topdressing and the dilution between fertilizers in the later stage. Why should sunshade net be covered in the construction of greenhouse? Prevent rain and release hail. Can reduce the impact of rainstorm and hail, its damage to crops in the shed, cooling in summer and autumn, sunshade net can effectively block the sun, reduce the temperature in the shed, avoid the harm of strong light and high temperature to crops, 3 moisturizing and drought resistance. The speed at which air communicates with the outside world becomes slower. The relative humidity in the shed will become larger, 4 heat preservation and anti-freezing. Covering the sunshade net in winter can provide ground temperature and has the function of preventing frost. Do a good job in the overall heat preservation of the glass greenhouse: (1) if the conditions permit, the construction of semi-underground border surface can improve the soil temperature of the glass greenhouse and play a good role in soil heat preservation.
Although, there are some minor complaints in the process. “before the introduction of the policy, I saw someone cooking hot pot on the lawn, hurting the grass. When they left, they also left some rubbish. ” Ms. Mak, a citizen, said. In view of this situation, according to the person in charge of the Yuntai Garden Management Center of Baiyunshan Scenic spot, the tent area of the park will be in charge of a fixed area, a fixed period of time and a special person. At present, two large lawns in Yuntai Garden are open for citizens to set up tents from 10:00 to 4 pm on weekends and holidays. Members of the public can set up tents and picnics. The garden will also provide sunshade facilities and designate garbage dumping areas. Kites and fire are prohibited on the lawn.
External sunshade system. Installed on the top of the greenhouse, pulled by the motor. Play the role of regulating the greenhouse sunlight regulation, shading, cooling, the system uses gear and rack transmission, press the switch button, the motor starts. The shading net is slowly expanded, and the external shading system can control the shading rate according to the needs of production management. Inner sunshade system, a sunshade screen system installed in greenhouse, and sunshade and heat preservation system in multi-span greenhouse. The internal shading system generally only plays a sunshade role in the south of China. Similar to the function of the external sunshade system. What materials need to be done before the construction of intelligent greenhouse
The turn of the stars of “in the other way, but also the other body” is the last school of the Murong family in Gusu. Car sunshade is a typical representative of this kind of martial arts, it can reflect heat to achieve the purpose of cooling. Place a sunscreen at the front windshield to prevent direct sunlight from raising the temperature in the car. It is understood that sunshades of better quality can reflect more than 70% of the heat.
It is harmonious with blue, white and so on. The top left look is elegant and gentle with a grass-green vest and a white lace dress. And the green dress is more convenient, with a sunshade straw hat as if to go on a picnic.
At the training course, she showed her hand-made pearl bags, straw bags, ribbon crocheted sunshade hats and other finished products. The exquisite hand-woven finished products attracted the attention of everyone in the training course, some people quickly snapped up their favorite bags or hats, and those who started late were filled with regret.
