Reflective material terminology explanation

Reflective materials are indispensable for making reflective products (such as reflective vests worn by traffic police or sanitation factories, reflective warning signs used on roads, vehicle license plates, and some common safety warning signs). Reflective materials can be used in dark environments because Its bright reflective effect provides a warning to everyone, thus greatly improving the safety factor.

At present, reflective materials for civilian use are reflective fabrics, reflective lattice sheets, reflective printing cloths, and the like. The lifespan of reflective materials is also very different, generally according to the manufacturer's process, the use of time is 3 to 7 years.

Reflective materials, the main technical indicators are retroreflective, retroreflective coefficient, incident angle, observation angle, glass beads technology, micro-prism technology, pressure sensitive adhesive, water film test method, etc., the specific terminology explained as follows:

Retroreflection: When a beam of light strikes a certain surface, the reflected light returns to the source along the opposite direction of the incident light.

Retroreflection coefficient: The retroreflection coefficient is the main parameter used to describe the retroreflective performance of retroreflective materials, and the retroreflectivity varies with the observation angle and the incident angle.

Incidence angle: usually refers to the angle between the incident light and the normal of the signboard surface.

Observation angle: usually refers to the angle between the incident light and the incident light reflected by the signboard back to the viewer.

Glass bead technology: refers to the reflective unit in the reflective material is the main glass beads, the need to plate behind the glass beads metal reflective layer. This is an early reflection technology and represents engineering grade reflective films and high-strength grade reflective films.

Micro Prism Technology: The reflective element in the reflective material is a triangular prism, which allows the incident light to achieve multiple total reflections in the prism. No metal plating is required, and the reflective efficiency is higher than the glass bead technology. Is the development trend of modern reflective technology, on behalf of the product is super-grade reflective film and diamond grade reflective film.

Pressure-sensitive adhesive backing: refers to the adhesive's performance is sensitive to pressure, as long as the adhesive is applied a certain pressure, can produce a certain degree of adhesive strength.

Water film test method: It is a simple and effective method used to test whether the aluminum plate is clean in the sign making process. The specific operation is: Pour clear water onto the aluminum plate. If the water flows smoothly and quickly, it means that it has been cleaned; if there is water droplets attached to the aluminum plate, it means that it is not clean yet. Continue cleaning.
