Characteristics and application of anti-static laminated board

The construction industry has always been a big market for the application of film-coated panels and the main driving force for the development of the color panel industry. With the application and development of film-coated boards in the construction industry for more than 30 years, more and more film-coated board products have been born and play an increasingly important role in the construction industry. The characteristics and applications of electrostatic film-coated boards are introduced as follows:
1. The generation of static electricity The molecules of different substances, the atoms and the different moments of mutual attraction to electrons can generate charges, which are called static charges. Even small static charges can generate high static voltages. In general, polymers with more groups tend to carry positive charges, and vice versa, they tend to carry negative charges. Static electricity is everywhere in our daily life. For example, when a person walks through a synthetic carpet in an air-conditioned room, a charge accumulation of 0 volts can be generated, and when the car door is opened in winter, the hand will feel clicked. The surface of conductors and semiconductors can also generate static electricity, but because the charge can be transferred on the surface and inside the material, there will be no accumulation of static charge on the surface. The polyester or fluorocarbon on the surface of the film-coated board is a high-molecular polymer, which is an insulating material. Once it is charged, it is difficult to remove.

2. The harm of static electricity a. Adsorbs dust and dust; b. Reduces the surface and performance of the product; c. Causes static discharge and causes combustion.
3. The working principle of anti-static color steel plate The electrostatic principle of the electrostatic film-coated plate is to add conductive materials to the insulating polyester coating, so that the original insulating coating becomes a semiconductor. With the installation of the grounding wire of the construction project, it can be The static electricity generated on the surface of the coated steel plate due to air convection and clothing friction can be introduced into the ground and disappear, thereby achieving the effect of static electricity.
4. Anti-static coated panels are mainly used in places with static electricity, high cleanliness, dust-free and sterile. For example: computer and server rooms, circuit board workshops, electronic production sites such as semiconductors and silicon chips, equipment production plants, production and use sites in the field of microelectronics, chemical factories, nuclear industry sites, photographic production and use sites, etc.
5. The performance of antistatic coated steel plate a. The processing performance and durability are comparable to ordinary polyester; b. The chemical resistance and solvent resistance are slightly higher than ordinary polyester; c. The surface resistance (Ω/CM2) is 10 of 6 power to 10 to the 9th power (ordinary polyester is about 10 to the 3rd power).
