Since most coatings use various combustible solvents as diluents, the static electricity generated during spraying is very easy to ignite and detonate the gas of these solvents during discharge. Therefore, how to prevent electrostatic hazards in coating spraying is a problem that can not be ignored. In order to prevent the harm of static electricity in coating spraying, firstly, the spray gun is equipped with a device to eliminate static electricity; The spraying construction personnel should preferably wear anti-static working shoes with resistance of 105 ~ 108, and must not wear insulating working shoes; To prevent the paint from flying, when the thin plate must be laid on the ground or on the back of the coated object, the plastic plate and other insulating materials shall not be used, but the thin plate made of conductive materials shall be used;
