Reflective film is one of the most widely used antireflective materials in today's society. Including white, yellow, red, green, blue and so on a variety of colors, to meet the needs of everyone. The reflective film uses a special process to combine the reflection layer formed by the glass bead and the polymer materials such as PVC and PU, which is a novel reflective material. What are the requirements for the use of the reflective film?
First of all, packaging requirements: each volume should not be less than 45.72 meters, the number of each roll length direction of the joint shall be not more than three, each volume of not more than four, more than 10 meters long and short. The membrane surface rough, sharp objects prohibited the use of brush, prohibited the use of chemical solvent scrubbing, so as not to damage the membrane surface.
Secondly, the film requirements: apply the 300# sand paper to the bottom plate before applying the film, then wash it repeatedly with the washing of ordinary detergent or laundry powder, then rinse the panel with clean water, until the bottom plate is completely dried, then it can film. The service life of the reflective film for manufacturers commitment period of use, the actual service life and use the material, environment, use and storage, processing and other factors of correct processors, with index of weathering performance of reflective film.
Finally, appearance requirements: it must conform to the provisions of JT/T279< highway traffic sign plate >. For old brand refurbishment logo, we must clear all old reflective film and reattach the new reflective film. The old aluminum sheet must be grinded and smoothed, the packaging requirements of the reflective film and the good bond strength with the new reflective film.
The reflective film has an important use in the road traffic safety industry. The stage scenery, the famous brand, the license plate and so on are also used. The reflective film has good solubility, salt spray corrosion resistance, impact resistance, flexural performance and high and low temperature resistance. It has won a consistent high praise by virtue of its excellent performance. The different levels of the reflective film are suitable for different industries.
1. The engineering grade reflective film is suitable for the traffic signs of the general road, that is, the usual, two, three, four, and temporary signs. Generally, it is divided into two kinds: pressure sensitive type and thermosensitive type. The use of the same kind of ink screen printing technology can make all kinds of patterns. Enclosed is a durable reflective film. Life is generally 3~7 years, according to the manufacturer's different.
2. The diamond grade reflective film is suitable for traffic signs of high grade highways and urban roads. In normal use, the luminance retention value after 10 years is at least 50% of the initial brightness value. The use of the same kind of ink screen printing technology can make all kinds of patterns. The luminance of the diamond grade reflective film is more than six times that of the engineering grade, and is more than three times of the high strength grade. The operating temperature is generally required at 18 to 28 degrees C.
3, high strength reflective film is suitable for traffic signs of general roads, namely, the usual highway, level 1, two, three, four grade roads and temporary signs. Application of MD1800 series acrylic Meida bread film reflective film, 1500 series of PET mask. The surface figures are 2 kinds of rhomboid and honeycomb. The life span is generally 10 years. It is suitable for aluminum plate and steel plate.
