Automatic powder coating line

Automatic powder coating line

For a full-fledged and automated process of applying powder paint, an automatic powder coating line is used in production.

AUTOMATIC LINE INCLUDES:

– spraying chamber;
– polymerization oven;
– drying oven;
– conveyor of the transport system.
– surface preparation line;
– recuperation system.

PRINCIPLE OF OPERATION

The automatic powder coating line allows obtaining a high-quality polymer coating even on very difficult surfaces. For this, the product goes through several stages before obtaining a stable polymer film. Let’s take a closer look at each of the stages:

AUTOMATIC LINE INCLUDES

Washing chamber

The first stage in surface preparation is cleaning, degreasing and etching with various chemical solutions. The washing chamber serves for this.

We produce different types of sinks:

Линия подготовки поверхности струйного типа

When designing the line, a place is provided for tanks with liquids for chemical cleaning, it can be located under the sink. The product passes through several compartments and sequentially, in order, is processed with the preparations necessary for the technology.

Drying chamber

After the metal has been chemically treated and rinsed, it must be dried at a temperature of 100 °C – 130 °C. Therefore, after the washing chamber, the product goes along the conveyor to the drying chamber.

The drying chamber is of four types, depending on the energy carrier: electricity, gas, diesel, solid fuel heating.

Heating method is convective. The drying chamber is equipped with a heating unit and has ventilation.

Thanks to the intensive circulation of hot air, the metal heats up and dries quickly.

The product that has passed through the drying chamber becomes completely dry.

This process is mandatory, since the quality and uniformity of the future applied powder layer depends on drying.

Spraying chamber

The spray booth creates ideal conditions for painting.

Externally, the chamber can be made of powder-painted ferrous metal, galvanized steel or plastic. The internal joints of the chamber are sealed and have large radii of rounding, which allows you to quickly and effortlessly clean the chamber when changing color.

The spraying chamber consists of a working chamber, a filter unit, a cyclone, a fine air purification unit, which allows you to leave warm air in the workshop and a control panel.

Thanks to the final filter block, the degree of air purification is maximized. Loss of paint no more than 5-6%: this paint, which has collected in the lower part of the cyclone, can be reused.

Cyclone

A cyclone is connected to the spraying chamber. It is designed to separate the air from the paint, which is sucked in from the spraying chamber.

Centrifugal air currents are created inside the cyclone body, created by the fans of the filter unit. Due to this, the powder particles settle along the inner walls of the cylinder and the cone.

A sieve is installed in the lower neck of the cyclone for cleaning secondary powder from debris, which automatically feeds into the main tank with paint.

The air purified from large particles of powder goes into the final filter through the hole in the upper part of the cyclone and is returned to the workshop.

Polymerization oven

With the help of a polymerization oven, the paint sprayed onto the surface is hardened. Polymerization process: when the oven heats up, the paint begins to melt, forming a viscous film. When heated in a powder paint polymerization oven, it penetrates into all surface irregularities and hardens, forming a polymer coating layer with the maximum adhesion rate.

The product warms up evenly over its entire area (the temperature difference does not exceed 5 ° C).

The type of furnace heating is provided in 4 variants, depending on the client’s capabilities: electricity (heating elements), gas, diesel, solid fuel heating.

The polymerization oven is controlled through the control panel, which allows you to automate the control process.

In the oven, the optimal air flow rate is thought out, which does not blow off the paint from the surface.

There are several types of polymerization ovens:

Quartz lamp curing oven

Печь полимериации на кварцевых лампах

Thermoblock polymerization oven

Печь полимеризации на термоблоке

Automatic conveyor

A special transport system is used to move products along the entire line. The quality and speed of the transport system directly affects the performance of the product painting. When choosing a system, the main indicators are speed, carrying capacity, square meters that need to be painted per shift.

We can manufacture a conveyor, both in a floor version and with an air-rail movement.
