1. Frame and mask:
The main components of the large light box are steel and plastic structures. The double frame of the base is welded with steel or stainless steel. The pattern cover is made of glass plate, organic glass plate, and light box cloth. The main components of the small-sized door, rod, and hanging light boxes are injection molding frames, and the pattern covers are mostly made of glass, plexiglass, or transparent plastic plates.
2. Pattern printing carrier:
According to the structure and production process of the print carrier of the light box, synthetic paper, inkjet film, self-adhesive adhesive film, light box canvas and other materials can be used (see Table 2).
Table 2
Material type Material name or variety
Film silver glossy film, back spray light box film, back spray wear-resistant film, pure white glossy ink-jet film, transparent transparencies
Paper-jet high art watercolor paper, high toughness photo paper matte photo paper, poster paper, transparent
Self-adhesive self-adhesive self-adhesive white glossy PVC, self-adhesive white matte PVC, self-adhesive transparent film
Light Box Canvas Pure White Gloss Art Canvas, Paulis Canvas, All Weather Outdoor Tape, All-Day Fake Outdoor Durable Fiber Cloth, All Weather Outdoor Self-adhesive Glossy Fabric
3. Auxiliary light facilities:
The auxiliary light of the light box (commonly known as lighting) is based on the structure of the pattern screen, the printing material, the thickness of the printing ink layer, and the pattern width. In the past, common fluorescent lamps were used. With the application of new lamps and lanterns, the auxiliary light of the light box has also evolved from a single lighting to various types of lighting. The resulting picture quality, uniformity and softness have been greatly improved.
Galavnized ground anchors are simple piles used for fixing pull lines or temporary fixation during construction. They are composed of one or more spiral bearing plates attached to the central axis. When in use, the ground anchors are rotated into the ground by rotating the ground anchors. In the following, the tensile force between the ground anchor spiral blade and the soil layer is used to achieve a fixed effect.
Spiral ground anchors are widely used in the construction of large poles and towers because of their large torque, short installation period, and stability of different soils.
Screw ground anchor application
Install transmission towers in the field
In long-distance power transmission lines, spiral ground anchors can be used to fix the bottom of high-voltage power transmission towers in environments with difficult transportation, high water levels, swamps, soft foundations, etc., and can cope with harsh outdoor environments and soils such as sand and gravel. Tower.
Installation of communication towers and power towers
Spiral ground anchors are suitable for the stabilization of the bottom of large communication towers and power towers due to their multi-angle structural torque and tensile force, with a tensile force of 80 kilolbs. The tower foot/iron column is fixed on a steel support composed of multiple spiral ground anchors or on a platform where multiple spiral ground anchors are combined together and poured into concrete, and the overall tower body is stable.
