The film structure sunshade is useful to resist ultraviolet rays: it is not enough to reduce the temperature in the sunshade. The film structure sunshade can also be useful to resist ultraviolet rays in the sun. Ultraviolet ray is one of the light waves. It can make our skin dark, deteriorate the skin quality, and deteriorate iron, steel, copper, plastic and other objects. After the membrane structure blocks the ultraviolet ray, the objects in the sunshade will be like those in the cool room in the hot summer.
Beautiful and elegant: besides being strong and useful, the film structure sunshade has another advantage, which will be beautiful. Orthotropic: membrane structure has two stress directions, which are non isotropic. The warp fiber of the membrane roll is the roll length, and the weft fiber is the width. The warp and weft have different limited tensile strength, tensile deformation, and tensile force deformation curves; The warp fibers are generally straight lines, and the weft fibers are winding up and down. Therefore, the mirror deformation is small, and the weft deformation is large. After special pre tensioning before coating, the warp and weft fibers have smaller crimp, making the two-way force bearing function similar; Nonlinear: the stress-strain relationship of membrane structure is nonlinear, and its nonlinear strength is related to the membrane structure, stress level and stress times; Inelasticity: the characteristics of membrane structure are related to the load. Under repeated load, the unloading curve and loading curve of membrane structure do not coincide. With the increase of the number of loading cycles, the difference of unloading loading curve gradually decreases, the degree of nonlinearity decreases, and the stress-strain relationship tends to be linear.

With the rapid development of the construction industry, glass awnings can be seen everywhere. What are the factors that affect the price fluctuation of glass awnings?
The price of glass canopy is generally related to the cost of personnel and materials in the market. Glass awnings from different manufacturers have different raw materials and prices.
The use of glass canopy not only has a good decoration function, but also has good sound insulation, wind resistance, heat preservation and other functions, which can withstand the wind and rain for people, so it is also very useful.
Membrane structure sunshade When there are higher specification requirements and 1-2 conditions are met, sunshade measures shall be taken, and the indoor (outdoor) temperature reaches or exceeds 29 ℃; Solar radiation intensity 240kcalm2 · H (1004.6kjm2 · H); Indoor sunshine depth 0.5m; If the indoor sunshine time exceeds 1H, the awning should be used for shading the doors and windows of low rise and multi-storey buildings. Not applicable to external shading of high-rise buildings. The raw materials, thickness, standards, dimensions and forms of sunshade materials, forms and standards of fixing devices, power of motors, power when using electricity and wind pressure of land for film structure sunshade are related to each other. It is necessary to obtain relevant technical data from professional manufacturers according to the specific project conditions, and select after induction and consideration. New design, beautiful color, multi-function hood! Rain proof, sunshade, wind sand. Many electric cars, motorcycles and bicycles are suitable for installation. Let ordinary electric vehicles enjoy the fashion of "cars". Core technology innovation: select high-tech
