Wall, furniture, car paint is very common in daily life, there is a common characteristic is that the paint on the surface of the wall and furniture will fall off for a long time, and the car will encounter the phenomenon of paint friction when driving. So we need to repair the paint, and the tool we need to repair the paint is the paint spray gun. What are the atomizing methods of the paint spray gun?
Wina mechanical reminder, paint spray gun in the choice of atomization, should take into account the following factors:

(1) Type of paint
The type of paint used determines the atomization pattern and the atomization method that should be adopted. Some coatings are more suitable for external mixing, and some are more suitable for internal mixing.
 
(2) Air consumption during atomization
The selected air nozzle consumption should be lower than the air supply of the air compressor, only in this way to ensure that the paint spray gun atomization can be fully supplied with compressed air, otherwise the air supply can not be met. Practical experience shows that for the electric air compressor, every 1hp(745.7w) increase in power can produce 4ft3(0.113m3) more compressed air with pressure of 10001b/in2(689.476kpa). The greater the air consumption of the air cap, the greater the spraying capacity of the coating, the faster the speed of covering the workpiece. Gas consumption of various pneumatic equipment at pressure of 100psi.
 
(3) Air cap and paint nozzle must be used together
Because not all air caps can be used with any kind of paint nozzle, so we should choose the nozzle that can be used. The user can know the correct nozzle collocation from the information provided by the equipment supplier. Each manufacturer of spraying equipment generally produces a variety of special paint nozzles, and describes in the data can be matched with the special air cap situation.
 
(4) atomization pressure
Refers to the air pressure used in the atomizing spray gun, the pneumatic pressure of the atomizing paint spray gun increases, and the required gas consumption will also increase. Generally, the air consumption at 207kpa, 345kpa and 483kpa is indicated in the data provided by the manufacturer of pneumatic tools. Because the higher the atomizing pressure is, the larger the gas consumption is, the larger the amount of the atomized paint is, so the gas consumption of the air cap should match the gas production force of the air compressor. For the air cap with small air consumption (air consumption), a small air compressor can be used, and for the nozzle with large air consumption with multiple holes, a high-power air compressor should be used.
