Epoxy anti-static floor is mainly developed for the special requirements of some precision electronic instruments, instruments and other production sites. It can effectively reduce the repair rate and loss of precision electronic products, and effectively reduce low-voltage static electricity to precision electronics. The hazards caused by the product.
We generally classify them by volume resistance, 10-6-100Ω for conductors, 100-1010 for semiconductors, and 1010-1018 for insulators. The resistance of the anti-static floor should be in the range of 105-109 Ω. When making an anti-static floor, not every layer is anti-static, because the resistance of the resin is generally between 1020-108Ω. In order to achieve anti-static effect, it is necessary to add conductive materials, for example, electric carbon black. Conductive mica powder, conductive fiber, alloy powder. The cement floor itself is electrically conductive. Generally, the antistatic primer is insulated, and then the intermediate coating and the topcoat are made conductive, so that the electric charge is dispersed in the plane.
Among such a variety of conductive materials, conductive carbon black is the best, but it is generally used for intermediate coating because of its dark color. Followed by conductive mica powder, because it contains conductive metal, but also has color, and the amount is relatively large, so it is more suitable for thin coating floor. The conductivity of the conductive fiber is very high, because it is actually formed by the probe pattern and the intermediate coated conductive layer, so it is suitable for conductive self-leveling.
