Generally speaking, two opposite corners are stretched first, four corners are fixed, and then driven from the middle of two long sides. Don't lengthen the first long side, just don't leak the white edge. The remaining long sides are stretched, and the last two short sides are stretched. It doesn't matter if there are some small wrinkles. Just two days in the sun.

Solution 1:

Holes are fixed with screws, usually with tie straps! If not, use all-purpose glue, three seconds (502) and spray glue. If it is the truss or iron frame of outdoor billboard.

Solution 2:

Generally, screw X, if glue is needed: glass glue (silica gel).

Solution 3:

You can use 502 glue.

Solution 4:

520 or all-purpose glue

Extended data:

Spray-painted cloth, commonly known as light box cloth, is a kind of spray-painted material mainly used for outdoor advertising, which is made of PVC as raw material and through a certain production process.

Production method:

1, scraper method

Scraper lamp box cloth technology is that liquid PVC slurry is evenly coated on the front and back sides of the base cloth with several pairs of scrapers, and then completely combined into a whole through drying process, and then cooled and formed. It is characterized by strong impermeability, tensile strength and peeling resistance. Because the scraper method is an integral product, the peeling phenomenon can be eliminated, and the strength of the joint can be greater than the product itself through welding.

At present, the width of light box cloth using this technology can reach 5 meters. Due to the complex manufacturing process, scraper materials generally need post-treatment, and the manufacturing equipment (surface treatment) is relatively expensive, and only a few can be produced in China. In China market, these products are mainly exported, and the prices are relatively high. The number of grams per square meter ranges from 400 grams per square meter to 2000 grams per square meter. The most representative ones are made in China, Zhejiang Jiufang Plastic Industry Co., Ltd. (Jiufang), UNIFLEX made in Korea and SIOEN made in Belgium.

2. Paste method

The sticking method of inkjet cloth is to heat the upper and lower layers of PVC film, adhere it to the middle light-guiding fiber net under the pressure of hot roller, and cool it to form. The biggest feature of this process is excellent ink absorption and strong color expression. Therefore, with the rise of large-scale inkjet industry, it has also brought infinite vitality to this inkjet cloth. At present, this kind of inkjet cloth is basically produced by domestic manufacturers, and its market share in China has exceeded 70%. Due to the mature domestic production technology, the products are exported to many foreign countries.

3550 spray-painted cloth

The base fabric, 500X500D, 9X9, is relatively heavy, with a weight of 320g/m2 to 440g/m2 and a thickness of 30 to 40g/m2. Its main properties are smooth surface, bright and thick spray paint and strong tensile strength.

4520 spray-painted cloth

The base fabric is 200X500D, 18X 12, and the weight is medium, 250g/m2-300g/m2. The thickness varies from 28 ~ 3 1 filament, mainly characterized by smooth surface, bright color, uniform thickness and average tensile strength. ..

5. Calendering method

Calendering method is to fully mix PVC powder with liquid plasticizer and other raw materials, and then adhere them to the base fabric under the pressure of high-temperature hot rollers. It is characterized by good surface finish and uniform light transmission, and has advantages in indoor lighting cloth. However, due to the limitation of equipment, the width is generally not more than 3 meters. The 645 and 945 lamp box cloths developed by American 3M Company are all produced by this process. In addition, Lexi light box cloth developed by LG is also a representative of this technology.
