There are many ways to classify the reflective membrane. Among them, the generally accepted classification principle is based on the basic structure of the reverse reflection unit, according to the reverse reflection coefficient of the luminosity performance of the reflective film front. But considering the different processes of the reflective film, some are specially designed to solve the non-positive retroreflection brightness, some are taking into account the performance of both aspects, and some are for the harsh weather conditions of the visual recognition needs, so this classification method, there are also shortcomings. Therefore, familiar with and master a variety of different reflective film application conditions and design functions, it is very necessary.
Traditionally, according to the structure of the reflective unit, the reflective film is divided into two categories, glass bead reflective film and micro-prism reflective film. Each class of reflective film also contains many types, such as micro-prism reflective film, due to the use of more advanced technology, its material selection and prism structure, there are many changes, can cope with more traffic needs. According to the form and technical features of the prism, micro prismatic reflective film can be divided into the remote back reflection ability good cutting Angle prism reflective film, close large Angle back reflection performance good cutting Angle prism reflective membrane, and various aspects demand the prism of reflective film, give attention to two or morethings performance day and bad weather conditions are good type fluorescent prism reflective film, The prismatic reflector film conforming to the traditional engineering retroreflector parameters and so on.
Glass bead reflective film appeared earlier, but its process changes are less, there are two main types, one for lens embedded reflective film, commonly known as engineering grade reflective film; One is a sealed capsule type, commonly known as high-intensity reflective film. In lens embedded type reflective film, due to its appearance has a long history, various manufacturers, in the long manufacturing process, using the lens diameter, density, corrosion resistance of the coating thickness is different, made a lot of kinds of reflective film, such as super engineering grade reflective film, mainly on the basis of engineering grade reflective film, with higher quality of glass bead, and increase the density of the glass bead, To get some brightness; Commonly known as the economic level of reflective film, mainly produced in China, is basically on the basis of engineering grade reflective film technology, by reducing the number of lens (glass beads) and the way of density, the two kinds of reflective film, economic grade reflective film, its reflection ability can't satisfy the need of traffic safety, more is to use in the business world, It is rarely included in the international traffic safety lighting standards.
According to the type of reflective film, reflective film can be divided into heat sensitive adhesive reflective film, pressure sensitive adhesive reflective film and no reflective film. The traditional reflective film used in the field of transportation facilities is mainly pressure sensitive adhesive. The pressure sensitive adhesive can be adhered to smooth, clean surfaces without heating, solvent or other preparation work. Traffic signs are usually pasted on aluminum or aluminum panels. The stickiness of the thermal adhesive is stimulated by heating and applying pressure to the material. Backless adhesive reflective film, usually used for traffic cone reflective tape, temporary roll warning signs and facilities column reflective tape with their own support materials.
