What are the spraying requirements of different spraying equipment？

With the continuous improvement of the scientific level, various coating products are also increasing. How to choose the appropriate spraying equipment for construction is a problem that every construction worker needs to pay attention to. Only by choosing the right spraying equipment can our painting be more energy-efficient, efficient and perfect. Today, we will learn the classification and characteristics of spraying equipment. Generally speaking, fluid spray equipment can be divided into three categories:

Air Spray Equipment
This equipment has a low paint utilization rate, and the paint transfer efficiency is only about 30%. Wave spraying is often prone to rebound and overspray. It not only wastes paint, but also causes considerable pollution to the environment. Since the paint is in direct contact with the compressed air, it is necessary to purify the compressed air, otherwise the moisture and grease in the compressed air will mix with the paint, resulting in bubbles, whitening and discoloration of the paint.

High pressure airless spraying equipment
Using this equipment can make the user more satisfied with the construction efficiency, because this equipment can improve the adhesion of the paint and prolong the service life of the paint. High-pressure airless spraying adopts high-pressure spray atomization, so that the coating particles can obtain strong kinetic energy, and the coating particles can reach the gap of the workpiece through this kinetic energy, thereby making the coating more dense, enhancing the mechanical bite force with the workpiece, and improving the adhesion. , effectively prolong the service life of the coating.

Electrostatic spraying equipment
Electrostatic spraying can be used in combination with air spraying and mixed gas spraying, and their respective advantages are integrated into a new spraying method. When a DC high voltage is applied between the grounded workpiece and the gun, an electrostatic field is created. When the negatively charged coating particles are sprayed on the workpiece, they are uniformly deposited on the workpiece surface after colliding with each other. Coating particles dispersed near the workpiece are still within the range of the electrostatic field. However, electrostatic spraying has certain requirements on the viscosity and conductivity of the coating. Not all coatings are suitable for electrostatic spraying, and equipment investment is also large.

When users use spraying equipment, they must be clear about their own needs, so as to better use this type of equipment. At the same time, different construction environments have different requirements for spraying equipment, which requires all users to pay attention to it!
