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. Martha MD1800 series acrylic reflective mask, reflective film which applies to the 1500 series of PET film industry. 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.
More people will pay attention to it:
The types of reflective film signs can be divided into two types: wet corrosion and dry corrosion. Wet corrosion refers to the corrosion of metals in the presence of water, and dry corrosion refers to the corrosion of dry gases in the presence of no liquid water. Because water is generally present in the atmosphere, chemical solutions are often used in chemical production, so wet corrosion is the most common, but the harm caused by dry corrosion can not be ignored.
Etching is also called etching: any metal can be etched. Etching is of quality standard. There are different requirements in etching speed, etching flatness, etching roughness, brightness, side corrosion and etching cost.
In general, any corrosion of the metal surface, all sub light, for light, will use the polishing process, in fact, whether it is chemical polishing or electropolishing, also is a kind of corrosion, but the corrosion of the weak.
In order to get a brighter surface after the first corrosion, there must be two conditions:
1, the original surface is brighter.
2, it is necessary to have the ingredients and proportions of bright corrosion.
Metal corrosion nameplate: available aluminum, aluminum alloy, stainless steel and copper. It can be applied to different types of corrosion reflective film labels. What are the different etching characters and professional corrosion background colors? The effect can be divided into words, convex and concave, etc. the quality is good and the price is favorable.
