The Difference Of Spray Painting Cloth, Light Box Cloth And Gridding Cloth
Spray painting cloth: commonly known as light box cloth, it is a kind of spray painting material mainly used for outdoor advertising spray painting production with PVC as raw material and certain production process. Including light box cloth, gridding cloth, banner cloth, oil painting cloth, and other digital painting textiles.
Light box fabric: it is a kind of light box signboard fabric composed of two layers of PVC and one layer of high-strength grid fabric, also known as Polaroid fabric. It can be divided into two types: internal lighting and external lighting. The main production methods are knife scratch coating, calendering and sticking. Key points of quality identification of light box cloth: thickness, tensile strength, ductility, weather resistance, light transmittance, flame retardancy, peeling degree, flatness, such as ink-jet, color reduction, etc. The most common large-scale outdoor advertising printing substrate is PVC composite polyester mesh. According to the technology, it can be divided into calendering method, knife scraping method and sticking method. According to different light sources, it can be divided into front light source (front lighting / external lighting) and rear light source (back lighting / internal lighting). The door width is about 1m to 5m, and the thickness is 0.3mm to 1mm. Suitable for solvent / weak solvent and UV ink.
Grid cloth: the mesh cloth is made of alkali or alkali free glass yarn and coated with alkali resistant polymer emulsion. The function is the same as lighting box cloth. Because there are mesh holes on the surface, it can avoid PVC basement membrane falling off due to outdoor wind, which can be used in windy areas. The production process is that polyester mesh (mostly biaxial warp knitted fabric) is impregnated with PVC resin paste and then heated and shaped by air box. The application of grid is more connected with the advertising industry, and the place involved is basically used for advertising of high-rise walls. Features: high strength, good alkali resistance
