Construction process suggestions
The electromagnetic shielding coating can be applied in various ways, such as roller coating, brushing, and spraying. It is easy to operate. The specific construction steps are as follows:
1) Clean up the dust on the base surface and keep the base surface clean and tidy.
2) Stir the coating evenly and then it can be directly constructed.
3) Make a decorative surface layer on the surface of the electromagnetic shielding coating, which does not affect the shielding effect of the product.
Product Introduction
Excellent radiation protection and electromagnetic shielding performance, low resistivity, and good function of eliminating electrostatic load; effectively shields electromagnetic wave interference, has excellent flame retardancy, extremely strong durability and weather resistance: resistant to low temperatures, acids and alkalis, water resistance, anti-corrosion and ultraviolet rays.
Uses
1. Applied in building internal radiation protection (anti-electromagnetic wave, electromagnetic protection coating), anti-electromagnetic wave interference and anti-static, etc.
2. Widely used in hospitals, telecommunications, substations, computer rooms and other large and medium-sized industrial computer rooms, petroleum industry, pharmaceutical factories, laboratories, classified places, electric vehicles, electronic parts production and other industries.
3. Applied to some plastics and rubber plastics that are easily affected by electromagnetic waves, such as the inner surface of plastic casings and chassis of precision instruments and military equipment, to form a conductive coating. Utilizing the conductivity of the coating, it has the characteristics of absorbing, transmitting and attenuating electromagnetic waves like metals, preventing external electromagnetic waves from interfering with the internal circuits and components of the instrument, and also preventing the internal information of the instrument from leaking to the outside.
4. Applied in the production of electromagnetic shielding/(conductive) rubber, conductive gaskets, conductive adhesives, electromagnetic shielding plastics, electromagnetic shielding plates, electromagnetic shielding films, waveguide ventilation plates and various wave-absorbing materials.
