The plastic spraying factory introduces the characteristics, operation, cleaning and maintenance of electrostatic plastic spraying equipment

When the plastic spraying processing plant is spraying, the surface plastic spraying cannot be separated from the solvent, because many parts need to use solvent resistant, so that they will not be melted.

The second is that the coating used is flammable and explosive, so many parts of the equipment should be flame retardant and explosion-proof to ensure safety in the production process. Moreover, the coating process requirements are relatively fine, so the equipment precision requirements are also relatively high. In addition, it is easier to plan the surface painting equipment into the production mode of assembly line, because it can save labor. The characteristics of electrostatic plastic spraying mechanical equipment can bring us more convenient benefits in the process of use, and can also save labor and cost.

One is solvent volatilization, which forms a solid coating film after solvent volatilization at room temperature, and can also be heated, such as single component perchloroethylene and nitrocellulose paint. Depending on the type of coating, it can also be heated to 60 ℃ to accelerate drying.

The second is the oxidative polymerization type. After the solvent volatilizes to a certain extent, the coating can absorb oxygen in the air to produce cross-linking reaction, and then it will dry.

The third type is heating curing type. After the solvent volatilizes to a certain extent, it will undergo polymerization and condensation reaction after baking. The last one is the curing agent curing type.

II. Different drying types of powders have different application effects, so we should also take these different factors into account when spraying. Before cleaning, the paint left in the plastic spraying equipment should be used up before cleaning. During cleaning, the solvent shall be injected into the container used by the plastic spraying equipment of the plastic spraying factory to store paint, so that the solvent can fully react with the paint, so that the residual paint inside can be completely cleaned. But when cleaning, don't forget to clean the spray gun. If the spray gun is not cleaned, it will easily cause nozzle blockage, which will affect the spraying effect. When cleaning, the spray gun can be removed first, and then the solvent can be poured in for cleaning.
