Water-like industrial paint is a common coating method - immersion.

Water-based industrial paint, according to the construction method is divided into roller coating, brush coating, spraying, shower coating, immersion, etc. , today we learn about immersion!
immersion refers to the coating will be completely immersed in the paint liquid, in all parts of the paint liquid will be coated after the paint will be lifted away from the paint liquid, naturally or forcibly so that the excess paint droplets back into the paint tank, in the process of removal, the solution of the thin layer retained on the surface of the work piece, after drying on the surface of the coating to form a coating method. Immersion is divided into manual and mechanical immersion. Manual immersion is used for intermittent small-volume production, and mechanical immersion is used for continuous mass production of assembly lines

. Immersion is more suitable for baking paint such as amino paint.
Some complex parts that require coating are not suitable for spraying or other widely used coating methods, and immersion is a selection process for finishing filled with angles, crevices and other hard-to-reach areas, making them ideal for complex metal components such as blower wheel coating, tool handles, and tool coatings such as storage racks with open geometry.
Immersion Tips
1, before immersion needs to be pre-treated work parts: to ensure that the surface of the work piece is clean, if necessary, can also be sand blasted and polished, increase the adhesion of the work piece can better ensure the coating effect.
2, the viscosity of the coating is one of the key factors of the immersion effect, it directly affects the appearance and thickness of the paint film. The viscosity is low, the paint film is too thin, the viscosity is too high, the level of the coating is poor, so the viscosity should be determined at any time during the immersion operation, the viscosity can be adjusted by supplementing the solvent.
3, after immersion to ensure that the work piece stays at the right time, to ensure that the parts that need to be coated with paint liquid.
4, when pulling out the workware to ensure a constant speed of extraction, without any quivering, can increase the uniformity and smoothness of the coating. The faster the withdrawal, the thicker the film will be before the coating can be reflowed back into the solution, pulling more paint to the substrate. Higher viscosity coatings are also thicker in immersion than low-viscosity coatings, and care is taken to control the extraction speed to ensure a suitable film thickness.
5, put forward after the need to hang the work parts to suitable excess paint drops, otherwise it is easy to film thickness up and down uneven or flow hanging.
the advantages of immersion
1, high paint utilization rate, unlike spraying atomization, the immersion process of excess paint will drip back into the immersion tank, almost no waste.
2 and is suitable for coating more complex work parts.
3, simple equipment, simple operation, small investment, easy to achieve mechanized operation.
4, high production efficiency, coated work parts can be coated both in and out at the same time.
the disadvantages of the coating
1, the variety of applicable coatings is limited, not suitable for fast-drying coatings, otherwise affect the smoothness of the coating film.
2, coating work parts color single, can only be used for color consistent coating, can not set color
3, coating effect in general, coating work parts easy to produce uneven coating thickness or liquid hanging phenomenon, poor coating decoration, only applicable to the appearance of low requirements of the work parts coating.
