Powder paints

There are many different types of powder paints. Produced on the basis of various resins and with various additives, in all possible colors according to standard catalogs, but also adapted to special color patterns.

The most common are epoxy, polyester and acrylic paints. They have different physical and chemical properties - always choose the type of paint carefully to meet the requirements of the product to which they are applied.

The process uses dry powder paints in the form of particles of various sizes - generally 10-100 microns.

There is a technology for painting powder coatings with water dispersion, however, it is not widely used due to technological requirements.

Powder painting technique.
There are two main ways of painting with powder paints:- spray painting- immersion painting (in a fluidized bed).Spray painting is done manually for small production batches or automatically for high volume production. The powder coating process is carried out in an installation called the Powder Coating Plant. (GMP).Such a plant can be a standard powder booth for small production and small details, or an industrial installation for large-scale painting, often of large dimensions.

 

Ventilation of powder coating plant


The construction of a well-ventilated cabin should meet the following assumptions:

stop the spread of powder outside the booth,
v> = 0.50 m / sec => kW m3 / h fan
prevent the accumulation of powder that is a potential source of explosion,
allow the disposal of unused powder for reuse or disposal,
be safe during use · increase application efficiency
