As a new industry, membrane structure It has been widely used in various industries. Today, we will mainly look at the film structure sunshade. The sunshade is mainly used to protect vehicles from direct sunlight. Under direct sunlight, especially in summer, the sun is very poisonous. It can be said that the membrane structure sunshade is an effective way to maintain vehicles. If the car is often exposed to the sun, its service life is easy to shorten, so this can show that Membrane structure sunshade The importance of
Membrane structure sunshade What are the benefits? There are many advantages of using membrane structure to make sunshade, which are mainly reflected in the following aspects.
1. Good sunshade effect: people's demand for sunshine varies with seasons. In winter, people yearn for sunshine. In summer, people hate sunshine, because the hot sun will damage outdoor objects. It is unnecessary to worry about this problem when using the film structure sunshade. It can effectively block the sun, let the sun be reflected by the film structure when it shines on the sunshade, and ensure that the temperature under the shed is not too high.
2. Effective UV protection: It is not enough to reduce the temperature in the sunshade. The film structure sunshade can also effectively protect against UV 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 as safe as if they were placed in a cool room in hot summer.
3. Beautiful and elegant: besides being strong and practical, the film structure sunshade 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 ultimate 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 degree, which makes the two-way force performance 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 between the unloading curve and the loading curve gradually decreases, the degree of nonlinearity decreases, and the stress-strain relationship tends to be linear.
