3M inkjet cloth is made of PVC powder, liquid plasticizer and other raw materials, which are fully mixed by calendering, and then bonded to the base cloth under the pressure of high-temperature hot rollers. It is characterized by good surface finish and uniform light transmission, and has advantages in indoor lighting cloth. However, due to the limitation of equipment, the width is generally not more than 3 meters. The 645 and 945 lamp box cloths developed by American 3M Company are all produced by this process.
Second, the difference between 3M spray-painted cloth and ordinary lamp cloth:
1, the outdoor ultraviolet exposure years are different.
The outdoor weatherability of high-quality film is 5 years to 10 years, while ordinary painting can only last about 10 months outdoors.
2. The saturation of color is different after lighting with light source.
Ordinary inkjet lamp cloth is very light and light in color after being polished at night, which is seriously distorted. However, the surface color saturation of 3M film light box is high, and the color is bright and soft after turning on the light, which is pure and eye-catching. Beautiful and conspicuous.
3. The strength of cloth is different.
Ordinary ink-jet lamp cloth is very poor in texture, thin and poor in tear resistance. Not only can it not resist typhoons, but it is also easy to make ends meet under a small external force every day. High-quality special lamp cloth for film pasting has good light transmittance, excellent flatness, typhoon resistance and long-term outdoor conditions.
4. The outdoor aging resistance of the two models is different.
Ordinary spray painting will turn yellow after one year until it turns black. High-quality film-coated lamp cloth can ensure that it will not turn yellow outdoors for three years, and the back of the lamp cloth has special mildew-proof treatment (see the parameters of 3M lamp cloth), which can ensure that the lamp box will not grow mildew and form yellow spots in rainy season.
5.。 The difficulty and effect of site construction are different.
Ordinary lamp cloth is thin and brittle, and it is easy to wrinkle during transportation and construction, resulting in lasting damage, while 3M film-coated lamp cloth is thick, hard and soft, and it is flat as a board after being hung tightly, with excellent effect.
