Basic knowledge of arm awning canopy

The film material for automobile sunshades is a film material with high strength and good flexibility. The fabric substrate in the center is divided into polyester fiber and glass fiber, while the resins used as coating materials include polyvinyl chloride (PVC), silicone, and polytetrafluoroethylene (PTFE), which are lightweight, flexible, small in thickness, light in weight, and good in light transmittance; Ability to reflect, absorb, and transmit natural light; It is not flammable or flame retardant; It has characteristics such as durability, fire resistance, and good air tightness; The surface of the film is treated with fluorine (coated with PVF or PVDF), which is not sticky and has good self-cleaning performance.

The structural forms of automobile awnings can be divided into steel structures, tension structures, and inflatable structures; According to the characteristics of membrane materials, it can be divided into permanent membrane structures (the service life of membrane materials can exceed 25 years), semi permanent membrane structures (the service life of membrane materials is 10-15 years), and temporary membrane structures (the service life of membrane materials is 3-5 years); According to the composition of the film, it can be divided into PVDF film, PTFE film, and ETFE film.
