Three Production Methods Of Light Box Cloth
Squeegee method: Scraper method light box cloth process is to evenly coat the liquid pvc slurry on both sides of the base cloth with several anti-scratch blades, and then fully integrate into the whole through the drying process, and then cool and form. The manufacturing process of the light box includes thermal transfer printing, UV printing, inkjet printing, light box fabric tensioning system and profile processing, light box fabric seam processing, thermoforming, slotted characters, computer engraving, etc. On the basis of the traditional bus waiting hall light box, the light box rolling system uses a large rolling system to make the static picture of the waiting hall become rolling, and the functionality is greatly improved. Advertising light box factory electric drill, cross screwdriver, screw, hacksaw, wood saw, shovel hammer, pliers, nails, latex, hook knife, wire saw, plexiglass glue. It has the characteristics of property impermeability, high tensile strength and strong peeling resistance. Because the doctor blade method product is integral, peeling can be eliminated, and the joint can be made stronger than the product itself by welding. At present, the width of the craft light box cloth can reach 5 meters.
Calendering method: The calendering method is to fully stir various raw materials such as PVC powder and liquid plasticizer, and then bond with the base cloth under the pressure of high temperature hot rollers. Its characteristics are good surface flatness, uniform light transmission, and advantages in inner lighting cloth. However, due to equipment limitations, the width generally does not exceed 3 meters.
Lamination method: The use of light box cloth in the lamination method is to form a PVC film with a two-layer structure on the upper and lower sides. Through different heating, it is laminated with the optical fiber mesh in the middle under the pressure of the hot roller, and it is formed by cooling technology. The biggest feature of this production process is that it needs to have an excellent inkjet ink absorption and strong color artistic expression. Therefore, with the rise of large-scale advertising inkjet printing in my country, it also brings infinite vitality to this type of light box cloth. At present, the market share of such light box fabrics in China has exceeded 70%.
