Clean and decontaminate the fire detector shell to ensure that the fire detector shell is clean, dust-free, and free of contaminants, and then perform anti-static treatment on the fire detector shell. The process is to configure anti-static paint as required and pour it Into clean glassware. The pouring amount is appropriate to submerge the height of the fire detector shell; the fire detector shell prepared for anti-static treatment is immersed in the anti-static liquid as a whole, and then taken out, drained, placed on the rack to dry, and cannot be inverted or tilted Place it to prevent the antistatic liquid on the surface of the casing from forming a sag or uneven thickness.
After the anti-static treatment of the surface of the fire detector shell, its surface resistance will be reduced to (5 ~ 15) × 106 ohm cm, so that the electric field on the outer surface of the fire detector can be basically uniformly distributed, and the phenomenon of static charge accumulation can be greatly cut back. In the subsequent operation process, the anti-static coating should be prevented from being damaged by external forces to ensure the protection of the anti-static film. Anti-static measures for workshops, equipment, etc. All conductors in the cleaning plant should be connected to the ground, and no insulated conductors are allowed; the electrostatic potential of the insulation in the cleaning plant should not exceed 1kV, otherwise it will cause electric shock and damage fire detection Devices and instruments; the ground in the cleaning plant building adopts static conductive rubber floor, its volume resistivity is 1 × 107-1 × 1010 ohm cm, and a layer of soft copper braided metal is laid between the conductive rubber floor and the plant floor Net; static conductive rubber floor, work surface, and seat cover pads should be statically grounded. The seat cover pads use anti-static fabrics and reliable static grounding with metal parts; staff wear anti-static work clothes and wear anti-static Wristband.
