What are the different types of powder -coating devices?
There are several types of powder coating devices used for coating metal. The most common types of powder equipment include electrostatic spray gun and fluid bed. They are used to uniformly revive the workpiece with powder and create a chip -resistant finish that is more resistant than the traditional finish. Other types of powder coating include recovery systems, spray cabins and drug furnaces. The basic fluid bed consists of a tank, air supply and plenum or membrane that allows air to pass but not solid. Once the air is introduced into the diaper, the thermoplastic powder is suspended or fluid. The heated workpiece is then immersed in the fluid powder. Some fluid beds also have the ability to electrostatically charge powder, allowing the use of stricter thermoset polymer instead of a thermoplastic powder.
between newer and other convertible types of powder coating are electrostaticSpray weapons. There are three basic types of spray guns powder. They all rely on a fluid bed or tank to hold the powder and air supply to fluidize the powder and deliver it to the weapon. The main difference between these three types of powder coating is the mechanism used for the application of hubs to the thermoset polymer.
The most used powder coating is corona. This type of weapon uses the power source to hand over the electrostatic charge because the powder leaves the weapon. TRIBO weapons create a charge with friction by accelerating the powder by a narrow passage before omitting the weapon and the weapon for charging the bell simply throws the powder from the bell -shaped edge.
Other types of powder coating devices used during the spraying process include spray cabins and EVTIP recovery. The right cabin is a cover that is designed to keep the coating to maintainEl powder contained in one area. The spray powder coating can be small enough to conceive a single operator or large enough to include a transport system for moving a large number of parts.
Many spraying cabins include a recovery system. Usually contained in the cabin shell uses the system for recovering the fan to turn fresh air into the spray cab and prevent exceeding leakage to the stand. This piece of powder coating can also help save money, as the rabted assault can often be reused.
If the thermoset polymer is used, there is another step in the process. The coated part must be cured. This step requires a piece of powder coating device called oven for treatment. It raises the temperature of the part sufficiently high enough to undergo a chemical change called the strengthening. Furnaces of the drug are available either by convection or infrared sections.
