What are the advantages and disadvantages of reflective film?
3, the product surface has a strong reflection of ultraviolet function, can effectively avoid winged aphids, thrips and other pests, and mitigate pests and diseases.4, effectively reduce soil temperature during the day and effectively raise ground temperature at night.
Has the following characteristics:1, increase crop yield and color.2, inhibit weed growth and reduce production costs.
Material classification and advantages and disadvantages:1, economic reflective film: (advertising level, commercial level) / license plate / maritime levelThe reflective principle of this series of reflective films is the same as the engineering level.2, engineering grade reflective film: the performance of this series of reflective film belongs to the People's Republic of China Department of transportation issued JT-T279-1995 standard fourth grade reflective film, reflective film is enclosed in a durable. The material has been used to make traffic signs since the early 1950s. In the small traffic flow and low speed area of motor vehicle, the engineering reflective film still has certain application.Engineered reflective films are suitable for general road traffic signs, i.e., regular, grade two, grade three, grade four, road and temporary use signs. Generally divided into pressure-sensitive and heat sensitive type of two. Using similar ink, screen printing technology can be used to make all kinds of patterns.
4, the diamond grade reflective film: the performance of this series of reflective film belongs to the People's Republic of China Department of transportation issued JT-T279-1995 standard first and second grade reflective film, reflective principle of it which is different from the engineering and high grade reflective film glass microsphere reflection principle, the latest technology but the use of reflective microcrystalline cube.Each of the diamond cubes in the diamond reflector is joined and arranged, and there are more than 930 cubic corners in the area of a square centimeter of material. The thin layer of microcrystalline cubic layer is sealed to form an air layer, so that the incident light forms an internal total reflection, so that the best reflection effect can be achieved without the aid of the metal reflector. Comparison of engineering grade reflective film and high strength diamond grade reflective film made of high hardness wear-resistant polycarbonate material and crystallite cube technology and traditional, reflecting its performance not only doubled, but also greatly improves the performance of wide angle. The brightness of diamond reflective film is more than six times of that of engineering, and it is more than three times higher than that of high strength.The reflective film is a new kind of reflective material formed by the combination of the reflecting layer formed by glass beads and other high polymer materials such as PVC, PU, PET, acrylic and PC.The main point to identify the quality of reflective film: film material, the Pearl rate reflecting coefficient of glass beads, beads, death rate, color uniformity, weatherability, adhesive viscosity etc..
