How Does Electrostatic Spray Gun Work?
In order to understand how an electrostatic spray gun works, you first have to understand how electrostatic discharges work. Electrostatic discharges happen when two substances come into contact with one another. The electrical charge within the substance which is creating the electrostatic release will either draw the charged particles away from the other or keep them in contact with one another. When this happens, you will find that the object has a small “bar” of static charge. This is very important because when the charge runs through the object, you are left with the object being charged.
So how does the electrostatic discharge happen? There are many different theories on this, but the simplest one is that an object is conducting when it has a small amount of charge. You can see this by touching your finger to a piece of glass and then touching the object next to it. If you finger is still static free, then the object isn’t conducting and the glass is conducting.
Electrostatic charges may occur because objects with higher charge ratings are more prone to becoming discharged than lower charge objects. It’s sort of like water running down a drain, or higher charge batteries being more difficult to start. These discharges may not be permanent. The only way to know for sure is to have an electrician check it out.
How does an electrostatic discharge occur? When you first put the electrostatic discharge spray gun to the test, you should hold the gun near the object to discharge it. You shouldn’t touch the tip to the object or to any metal surfaces because you could conduct charge while touching the object. The discharge should only last a few seconds or less.
How long does an electrostatic discharge last? Some of these devices can have a life expectancy of up to one year. There are discharge devices that have a life expectancy of three years or more. This is because the discharge tube is often deep enough that it doesn’t take long to discharge all of the charge that was put into the device.
What happens if there’s an incorrect amount of charge? This is one of those things where sometimes a test isn’t perfect. Sometimes a discharge doesn’t occur because the gun didn’t discharge all of the charge that was put into the object. In this case, you have to replace the gun.
Where should I look for signs of a problem? The discharge tube should go into the venting system of the unit. This is one of the most common locations for this type of discharge.
Should you be using one of these? You should only use one of these in situations where you need to provide a static shield for certain materials. You wouldn’t want to have to use an electrostatic spray gun on something that’s electrically conductive. However, you could use one of these on something that’s not conductive and then have something that’s both electrically and conductive.
Can you just place anything on the surface of the object and it will discharge? Yes, you can. However, you have to make sure that you place something that isn’t conductive on the part of the object that it’s going to discharge onto. If you put something like a coat of paint on the object, you run the risk of it being electrostatic.
How do I know when I’ve done it right? When you get the gun to discharge, you’ll hear a small pop. This is because the charge has gotten into the object and is releasing that charge.
Is it expensive to buy an electrostatic spray gun? It’s not expensive to buy the gun in general, but it’s a bit pricey to buy one with the best features. There are some guns that feature a faster firing rate, higher durability, and other features. For the best bang for your buck though, go with a cheaper model and make sure that it’s able to handle the job that you need it to do.
How many bottles do I have to spray per hour? You have to spray a large area at a time in order to be able to get good results. Also, this assumes that you’re using the gun in an open area like a workshop. If you want to be able to discharge it effectively in a closed area such as a room, you need to increase the number of bottles.
