Especially in some high-end cars and concept cars, natural hemp fiber composites have been used instead of chemical fiber composites such as glass fiber and other chemical fiber composites, such as car interior door panels, miscellaneous boxes, truck floor, spare tire cover, seat backrest, dashboard, seat armrest, roof interior decoration, sunshade panel, luggage compartment decoration board and so on.
“Operation Bright window” is mainly for the management of vehicle driving safety, because the role of windows in addition to ventilation, but also assume the role of line of sight is transparent or not, is one of the important ways for drivers to observe the road. As we all know, the windows of the original car are transparent and colorless. After buying the car, most people will choose to stick a film, and even some car owners like to put on a dark film, so that they can avoid direct sunlight in summer. However, the dark film on the car window has a great hidden danger to the driving safety and is not allowed. According to the “Technical conditions for Motor vehicle Operation Safety” (GB7258-2017), private car window film has the following requirements: 1, the van window shall not be affixed with “specular reflection” sunshade film; 2, the visible light transmittance of the front windshield of the van and the rearview mirror of the driver should be greater than or equal to 70%, and the visible light transmittance of all windows should be greater than or equal to 50%.
The sunshade and heat preservation system on the top of the greenhouse. In order to improve the adaptability of the system, greenhouse construction manufacturers, so that it can be extended to most of the solar greenhouse built in the northwest, Gansu greenhouse construction, the system uses steel cable drive mechanism. Its working principle is that the motor drives the drive shaft to run, and the tight wire sleeve on the drive shaft turns the circumferential motion into linear motion. The aluminum drive card connected with the drive line drives the driving side aluminum profile to move parallel on the curtain line through the word connection, and the driving edge aluminum profile pulls one end of the curtain slowly to unfold and fold, that is, after all is folded, the opening and closing limiter switch is triggered respectively, the motor stops, and the operation is over.
Car interior accessories include dashboard, door guard, steering wheel, seat, ceiling, floor mat, sunshade, storage box, ashtray, etc., as well as some ancillary equipment such as audio, air conditioning, communications, television, lighting and so on. All kinds of equipment, function, shape and structure are very different, how to combine them organically to form a unified, coordinated and beautiful design? These are all things that designers should consider.
It is understood that at present, the materials used in the tea bag of the love cool tea shop are purchased by volunteers for dozens of yuan each; the sunshade used by the tea shop is sent by the China Resources Wanjia supermarket, a community party co-construction unit, on the 10th anniversary of its establishment; the cabinet for the discharge teapot is discarded furniture that others do not want; the old thermal insulation bucket was broken, and this year it has been replaced with a new one from Zhaolongkou street.
This kind of flower planting greenhouse is widely used in most areas, especially in the south. The single-family arch shed is mainly made of plastic-coated steel pipe or galvanized steel pipe, the surface is covered with film, and air vents are added on both sides. The utility model has the advantages of simple structure, low cost, easy construction and maintenance, long service life and strong resistance to wind and snow load. Its biggest deficiency is its low heat preservation capacity and high operating cost in winter, so it is suitable for breeding non-tropical flowers with low temperature requirements. Of course, we can add two-layer film on the original basis, increase the curtain machine quilt and other thermal insulation equipment, sunshade can effectively improve the arch shed temperature.
