Teflon Roof Structure

The roof steel structure in the terminal 2 building of yancheng nanyang airport has a large span and a considerably difficult construction.

Teflon roof structure. Few solid substances adhere permanently to a teflon industrial coating. What are teflon and pfoa. Teflon industrial coatings are desirable for use across many applications based on the following properties. To ensure construction safety a construction monitoring scheme was.

Building codes and roofs. Polytetrafluoroethylene ptfe a strong tough waxy nonflammable synthetic resin produced by the polymerization of tetrafluoroethylene. The structure supports 190 000 sf of polytetraflouroethylene ptfe fabric a teflon coated membrane installed by birdair that is light in weight yet incredibly durable in keeping out the elements especially the sun.

As a result the low surface adhesion properties in the ptfe structures easily cleaned by rainwater and immune to uv radiation. The article focuses mainly on birdair s contributions to the development of the technology. Ptfe or polytetrafluoroethylene is a teflon coated woven fiberglass membrane that is extremely durable and tolerant of even the most extreme weather elements. This makes it ideal for large scale roof and tensile membrane structures.

Polytetrafluoroethylene ptfe is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. Tacky materials may stick temporarily but almost all substances release easily. This tensile fabric roof material has a life span of over 25 years and is manufactured in. A short history of the use of teflon fabric in the construction industry is available on nasa s technology transfer program s website.

Teflon is a brand name used for a group of man made chemicals the most common of which is polytetrafluoroethylene ptfe. Another popular brand name of ptfe is syncolon by synco chemical corporation. The woven fiberglass gives ptfe coated glass fiber its mechanical strength and providing the membrane with maximum flexibility. According to the project characteristics the construction scheme of the roof steel structure follows the principle of subareas and substeps with the truss lifting in segmentation.

Ptfe is used world wide as the preferred material for large scale permanent tensile structures or structures requiring long life and with specific construction code compliance requirements ptfe has excellent weather temperature and chemical resistance in addition to its durability and strength. It has a wide variety of uses because it is extremely stable it doesn t react with other chemicals and can provide an almost frictionless surface. Where are they found. Ptfe has been in commercial use since the 1940s.

The well known brand name of ptfe based formulas is teflon by chemours. A range of ptfe material types is available that include ptfe coated glass fiber ptfe glass mesh and silicone coated glass fiber.
