What is the process of powder coating?

The powder coating process is a dry painting process that is mainly used for metal coating. There are several methods for applying powder. The most commonly used method is to spray electrostatically charged particles of pigment and resin on an electrically grounded piece. The heat is used to melt the powder, causing the flow, creating a thin film and finally dry on a hard, scratch resistant shell.

As with any painting task, the most important step in the process of coating the surface preparation powder is. Before applying the powder coat, the metal surfaces are thoroughly cleaned to remove oils, dirt and grease. After cleaning the metal, it is generally rinsed and serves an acid bath that etch the surface. Its up or slightly rough surface helps ensure proper adhesion and even distribution during the powder coating process.

The next step in the process is the real application of powder. The application method differs depending on the type of powder used. The main types of media usedH In the powder coating process are thermoplastic powder and a thermoset polymer. Both types of powder rely on cure of heat, but do so in different ways. The hot metal causes the powder to melt, flow and then harden when cooling. Thermoplastic powder is not subject to any chemical change because it solidifies. This means that the finished work can often be re -heated to equalize any thin or uneven places at the finish.

Thermoset polymer is applied to work at the room temperature and then cured in the oven. Part is heated and held for a specified period of time at 320-410 degrees Fahrenheit (about 160-210 degrees Celsius). During this time, the polymer will undergo a chemical change known as "amplification". The healing of the thermoset polymer occurs in four phases, including melting, flowing, creating a gel and finally cure on a hard shell.

For powder coating EXIt will be inspired by several types of weapons that can be used in the process of coating the powder. In general, everyone achieves the same result in different ways. These powder coating tools are designed to fluid medium colors and electrostatically charge particles when they leave the weapon. The main difference from one weapon style to the next is the method used to introduce a charge.

Some powder coat experts also use a piece of equipment called a fluid bed during the powder process. The basic fluid bed system includes a tank for holding the powder, a charge for insertion and low air pressure supply. When the air enters the tank, the charged powder is fluid or suspended in the air column and often resembles a boiling liquid. The part then immerses in the suspended powder and then cured. The fluid bed method allows powdered water to apply a stronger coat of one application.

The

powder process contributes to a piece of greater thickness than traditional painting methods. This is particularly important for items, toTheré should be together after the powder coating. If the working piece is dismantled into a powder coating, it may require some grinding or grinding when assembling.
