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

However, the effect of indoor shading is not as good as external shading, it only blocks the light, but not the heat. When the light encounters the inner shading facilities, the radiant heat has already entered the room through the glass, and the glass temperature will rise very high. As for the external sunshade, only that part of the sunlight will reach the outer surface of the glass window directly. In general, bright indoor blinds can only block 17% of the solar radiation heat, while the outdoor horizontal sunshade with an elevation of 45 °south can block 68% of the solar radiation heat. The shading effect of the two is very different.

with a sunshade.

Gansu Sunlight Board Wholesale, Lanzhou Sunlight Board Factory integrates daylighting, heat preservation and sound insulation, which can be used for greenhouse, furniture canopy, office sound insulation, outdoor advertising light box and so on. Foreign countries even appeared in addition to the supporting structure, pure polycarbonate material of large transparent lighting house, a sunshine, crystal transparent, warm and pleasant. In terms of greenhouse construction, there are greenhouses built with sunboards, gables and sidewalls using sunboards; in terms of greenhouse efficacy, there are production-based greenhouses, trade greenhouses dominated by flower trading centers, and greenhouses dominated by scientific research. Sunpanels are a widely used building material and can also be used in sunshades and canopies.

≥ 9 million pixels, including high-definition integrated embedded camera, high-definition lens, outdoor shield, camera built-in network signal lightning protector, power adapter and so on. GMOS deep learning chip is used. Support front window pendant, annual inspection logo, smoking, driver face recognition, cab face matting, sunshade recognition and other detection functions. The face matting function of the master and co-driver is supported. In a single-lane scene, the location, speed, vehicle model, driving direction and license plate type are supported as trigger conditions for snapping. Support human detection, tracking, capture, support front and back capture; in the same video screen, up to 100 moving human targets can be detected at the same time. On the premise that the bayonet detection of human body / face is configured with 3 snapshots, the best image is supported for re-screening.

two。 Facilities are reinforced. First of all, we should do a good job in strengthening the greenhouse and other facilities to prevent the snow from crushing and collapsing the facilities. If the film is damaged, it should be repaired in time. When there is heavy snowfall, the snow on the facility should be removed in time to reduce the pressure on the facility, increase the light transmittance of the film, and reduce the freezing low temperature caused by melting snow. When removing snow, you should gently push it to avoid piercing the greenhouse film. The greenhouse that is crushed and deformed should be strengthened and repaired immediately. If it cannot be repaired, it should be covered with film, grass curtain or sunshade net in time to improve the heat preservation effect.

Automobile manufacturing industry has always been an important consumer market for polyurethane products. The interior decoration of foamed polyurethane plastic for bridge car includes seat cushion, headrest, sound insulation, dashboard, sunshade, door panel, roof lining and so on. Car polyurethane purchased parts include bumper, flow stopper, front and rear ribbon, grille, rear side plate, door panel, fender and so on. The application of polyurethane in automobile is expanding day by day because of its good plasticity and strong application of material properties.
