The main function of ESD warning tape
We often use tape in our daily lives. Have you heard of ESD warning tape? ESD warning tape is easy to see on the floor or floor of the workshop and is generally used for warning purposes, that is, to identify an important item or area. In order to facilitate the manager's management of the workshop. Made of anti-static OPP material. It has the characteristics of discharging static charge and has transparency. When in use, only electrostatic voltage below 100V (generally tape ≥5000V) is generated, which greatly reduces the electrostatic hazard caused by product packaging. It is made by coating pressure-sensitive glue with antistatic agent on the surface of OPP film, and after antistatic treatment. Characteristics of ESD warning tape:
1. Strong viscosity, can be used on ordinary cement floor;
2. Compared with painting on the ground, the operation is simpler;
3. It can be used not only on ordinary floors, but also on wooden floors, tiles, marbles, walls and machines (and painting on the ground can only be used on ordinary floors);
4. The paint cannot draw two-color lines.
ESD warning tape can be used for floor area warnings, packaging box sealing warnings, product packaging warnings, etc. The color is black on yellow background, Chinese and English warning slogans, and the viscosity is oily extra-high viscosity rubber glue. The surface resistance of the anti-static warning tape is 106- 109 ohm, warning tape is used to identify warning areas, segment risk warnings, label classification, etc. There are black, yellow, red, and white lines to choose from; the surface is resistant to wear, can accept high-flow pedals, and has good adhesion. Certain anti-corrosion, acid-base properties, anti-wear.
ESD warning tape can be divided into: yellow and black twill reflective warning tape, red and white twill reflective warning tape, yellow and black regular pattern reflective warning tape, red and white regular pattern reflective warning tape, solid color reflective warning tape, reflective car sticker, etc.
The color of the whole roll of the good tape is not much different from the color of the one after it is unrolled. This is because the good tape has a strong masking property and there is no color overlap. To apply impurities to the film of doped inferior tapes, only the relatively backward direct gluing method is used, so there are often large impurity particles that are not completely dissolved and jamming occurs. Therefore, the tape often has problems during use. line. Another way to distinguish is to look at the surface of the tape. Many tapes have bubbles when they are just slit into a finished product. The bubbles will basically dissipate after being placed for a week. The surface of the tape with pure tincture glue is smooth without any white spots. Some tapes doped with impurities have a lot of irregularly distributed white spots, which cannot be removed by hand pressure, which is different from air bubbles.
