Paint spraying and powder spraying are two completely different painting methods. Paint spraying is to use compressed air to disperse liquid paint (commonly known as paint mist particles) to adhere to the surface of the coated object, while powder spraying is to use compressed air to disperse powder mist particles under the action of high-voltage electrostatic force to adhere to the surface of the coated object through the electric field.

The correct name for powder spraying is electrostatic powder spraying, which can not be simply completed with a spray gun. The electrostatic powder spraying equipment consists of a powder supply bucket (powder is supplied by compressed air), a high-voltage electrostatic generator and an electrostatic powder spray gun. The types mainly include outdoor powder and outdoor powder. The indoor powder is mainly epoxy resin type. The outdoor powder is mainly polyester resin type; And paint are two ingredients.

The paint is analyzed and calculated according to: polyurethane paint: the solid content of the paint is 40%, the cost of the paint is 50 yuan, the air spraying can spray: 6 square meters, about=8 yuan/square meter, and the primer is about 7 yuan/square meter; The total cost of at least two spraying operations is about 15 yuan/square meter.

The powder is analyzed and calculated according to the epoxy powder: the spraying thickness is about 60um, and the solid without solvent is 100%. (Zero emission can be achieved, and the powder can be recycled) The cost of powder coating is 20 yuan/kg, 1 kg of powder can be sprayed for 8 square meters, and the total cost is about 2.5 yuan/square meters. The powder needs to be solidified, needs heat energy, and the heating cost is 1 yuan/square meter. However, large workpieces are machine chassis, peripheral shells, electrical boxes and other products, and the thickness is thick, The heating cost is about 3 yuan/square meter, and the total powder spraying cost is 5.5 yuan/square meter.

Other cost analysis:

Water curtain cabinet or dry paint spraying room is required for painting, because 30-40% of the paint is wasted, and this paint also needs to be treated. The treatment cost is about 0.5 yuan/square meter, the utilization rate of powder is basically 100%, and the recycled gas is discharged indoors, without treatment cost; The paint contains formaldehyde, toluene, xylene and other harmful substances, which cause great harm to workers, and the secondary spraying increases a lot of manpower and material resources; Workpieces sprayed with powder: the coating is thick, which can cover some, and the paint can not make traces; In addition, the coating after powder curing is hard, not easy to touch, and the machine equipment is more high-end.
