户外广告牌施工说明
In my personal experience, the following materials are needed for the production of outdoor billboards:
(1) Steel structure. Generally, the billboard structure will be made of steel structure, which will have a longer service life and better safety.
(2) Hot-dip galvanizing treatment. Today’s outdoor billboards are recommended to use hot-dip galvanizing treatment, which has a high safety factor in anti-rust and reduces later maintenance costs.
(3) Three-sided flipping. Some outdoor advertisements use a three-sided flipping effect, making the picture three-dimensional and dynamic and attractive.
(4) Some use inkjet printing cloth, the advertising picture is clear and the cost is relatively low.
(5) Billboards that use the light box effect of LED light sources have better effects at night.
If there is a base plate, it is usually tightened from the four sides with ropes. Ordinary small billboards do not have a base plate in the middle. In this case, it is best to use special glue for inkjet printing commonly used on the market. In order to achieve the best viscosity, the following conditions must be met: the billboard should not be too far away from the wall, and the normal distance should be within 1 meter. When bonding, wrap a circle of spray-painted cloth strips around the billboard, double The surface must be fully glued and fixed with 3 seconds glue first. Flattening a picture is a small technical task, and it's best to have someone show you how to do it. First fix the two corners on one side, then on the other side, fix the tightening point on the other two corners, fix the middle, and then the middle of the opposite side. After everything is fixed, if it looks flat, then talk about solidification. The pre mise is that the cloth must be stretched hard in every movement (except for the first point), and finally it will be reinforced.
The outdoor printing fabric is a light box sign fabric composed of two layers of PVC and one layer of high-strength mesh cloth. It is divided into two types: internal lighting and external lighting. Scope of application: indoor and outdoor advertising signs, digital inkjet printing, screen printing, car body awnings, decorative partitions, membrane structures on building ceilings, etc. Width: 1m-3.2m. The material of the inkjet cloth: high-density woven cloth of PP (polypropylene) material, which is the same material as the colorful striped cloth used for wind and rain protection, but the latter is covered with film. Glass fiber should not be used. Glass fiber is generally used in industries such as machine-made asbestos tiles as reinforcement. Inkjet printing cloth generally comes in a roll of 100 meters, and one roll weighs about 100 kilograms. Inkjet printing cloth of different quality levels comes from different raw materials. The thickness of the silk and whether it is high-strength silk are all very important factors. PBC is made in a variety of ways, and the differences in the content of each chemical element will also affect the UV resistance, mildew resistance, and thermal deformation of the inkjet fabric. On the PVC coating, applying an auxiliary transparent acrylic coating is also an option, which can protect the PVC coating.
