Teflon (PTFE) construction membrane material:
As a new kind of building material, PTFE fiberglass membrane has been recognized as the "sixth building material" after brick, stone, concrete, steel and wood. The membrane structure is the new generation building after "brick wood structure, reinforced concrete structure and steel structure".
Membrane structure is a new form of building structure, which integrates architecture, structural mechanics, fine chemical engineering, material science, computer technology and so on. Its surface can be changed with the architect's design needs, combined with the overall environment, building a landmark image project.
Under the sunlight, the interior of the building covered by the membrane is full of natural diffuse light. There is no strong contrast between the lighting surface and shadow. The indoor space visual environment is open and harmonious. At night, the lights in the building illuminate the night sky through the roof membrane, and the shape of the building shows a dreamlike effect.
The main characteristics of film material are: light weight, high intensity, fireproofing, good capability of self-lustration, not impacted by the ultraviolet radiation, resisting impotence caused by bend, resisting contorts, resisting aging, long using life; and it has high light permeating rate and low heat absorbing rate. Because of the invention of this membrane material, the membrane framework constructions become the permanent construction.
Application:
Sports and leisure venues, exhibitions, Expo halls, terminals, high-speed railway stations, shopping malls, schools, office buildings, hospitals, villas, residential buildings, factories, cars, trains, ships and other indoor and outdoor construction sites. It can meet the special functional requirements of different customers, such as fire prevention and non flammability, heat insulation and energy conservation, environmental protection, sunshade, ultraviolet resistance, light regulation, local air purification, hydrophobic antibacterial, anti mildew, self-cleaning and other special functional requirements.
