Manual spray guns I wouldn't know much about ordinary people, but for those who are involved in decoration construction, they are familiar with the decoration tools. It is a kind of more professional equipment. It will only be used in professional situations. We will not see it in our daily life. Next, we will specifically explain the principle of the manual spray gun , and how to use the spray gun. 
The principle of manual spray gun
1. We have rarely used or seen manual spray guns in our lives, but in order to be able to better understand its related advantages and principles, we look specifically at the basic situation of manual spray guns. Manual spray gun, as its name suggests, is a two-handed painting equipment. The paint referred to here refers to a variety of paints, not paint. Manual spray guns are spray paint tools. It is mainly used for the surface treatment of products. Strictly speaking, manual spray guns are a kind of painting equipment. 
2, the other is the problem of the principle of manual spray gun, we continue to understand, first of all it is the use of compressed air, and then the paint becomes a small atomized droplets, so that when used like a spray, then Spray on the surface of the object with the airflow. The manual spray gun is mainly composed of a nozzle, a spray gun and a gun body. At the same time, the manual spray gun needs to be connected with a pneumatic device so that the air pressure will make the paint atomize.
How to use spray gun
1, before using the spray gun, we must first do some related preparations, the air intake port of the gun body to install a compressed gas source, and then connect the trachea, adjust the pressure 0,45-0, 5Mpa pressure. Charge the paint with the corresponding diluent and mix it up and adjust the viscosity to "Ford Cup No. 4" 17-24S. The paint with impurities needs to be filtered and then the paint is introduced into the paint tank. Adjust the fog width, rotate the fog adjusting screw clockwise until it is tightened to obtain a circular cross section. If you rotate counterclockwise, you can obtain the width of the elliptical cross section you require, and according to actual needs Adjust the length. 
2, when the spray gun is used to adjust the amount of spray, then first adjust the amount of switch to the right direction, so that the needle plug to reduce the open stroke, the paint output is reduced, counterclockwise rotation, ejected The volume gradually increased. The air conditioning will rotate the air conditioning screw clockwise, the air volume will gradually decrease, and the air volume will increase gradually as it rotates counterclockwise. When you use it, slightly move the trigger to open the valve, but the needle plug does not open and the compressed air is blown out of the airflow nozzle. At this time, you can blow off the dust on the exterior and continue to move the trigger backwards. The spray nozzle sprays paint mist.
3. After the spray gun has been used, it needs to be cleaned and maintained. The leftover material in the spray gun canister is cleaned out, cleaned with thinner, and the thinner is poured into the paint can for eruption. To clean the paint road, until the paint inside the spray gun is clean and clean, otherwise the remaining paint inside the gun paint will dry up and block, damage the spray gun, wash clean and dry with a clean soft cloth. Do not use sharp Metal Wire through the nozzle and air nozzle holes, otherwise any damage will cause abnormal spray, spray gun can not be soaked in the diluent for a long time when cleaning. The main parts of the spray gun are made of aluminum alloy and brass raw materials, so it is not suitable to touch the acidic and alkaline medium to prevent corrosion damage. 
The above introduction to the principle of the manual spray gun and related content of how to use the spray gun are introduced here. I hope this helps everyone.
