Theoretically, high-gloss curtain coating machines can use water-based paints, but certain conditions and equipment adjustments must be met. The key lies in the ability to consistently control the paint's flowability, drying speed, and gloss recovery.

Whether a curtain coating machine needs a UV curing machine depends on the coating system used. If the curtain coating machine uses UV-curable coatings, then a UV curing machine is necessary; if it uses thermosetting or air-drying coatings, a drying oven or natural drying line can be used.

A curtain coating machine is a device that applies coatings by utilizing the principle of a free-falling liquid stream. A roller coating machine, conversely, is a coating device that transfers paint onto a workpiece surface through mechanical contact.

UV paint differs from traditional solvent-based or water-based paints; its viscosity characteristics, reactivity, and curing mechanism are more complex. Therefore, it must be used with a specially designed UV curtain coating machine.

Basic Configuration (Suitable for small and medium-sized furniture factories) Production line process: • Feeding → Dust removal → Curtain coating machine → Leveling → UV curing machine → Unloading

Ideal workpieces for curtain coating machines typically possess the following characteristics: • High surface flatness • Regular geometry • No obvious depressions or protrusions • Ability to pass through the liquid curtain zone at a constant speed These conditions indicate that curtain coating machines are inherently more suitable for planar or simple geometric shapes.

That adjusting the coating thickness mainly relies on the balance between flow rate, viscosity, and conveyor speed. This means that a curtain coating machine can achieve both thick and thin coatings, provided the parameters are set correctly.

The coating thickness of a curtain coating machine is determined by both the liquid flow rate and the conveying speed. If the flow rate is too high and the speed too slow, the coating thickness increases, and the surface tension is insufficient to support gravity, easily leading to sagging.

Furniture panel surfaces typically require a smooth, even surface, consistent color, and good adhesion and abrasion resistance. The Curtain Coating Machine's coating method perfectly meets these requirements.

The curtain coater machine is not a "universal device." It is more suitable for continuous, flat, and flexible material coating processes. For three-dimensional workpieces or irregular surfaces, traditional spray coating still offers greater flexibility.
