However, the cost is high, and the spraying technology is highly required, requiring more than six or seven times or even ten times.
2. The advantages and disadvantages of open paint
Open paint means that you can see the natural characteristics of the wood grain, just change the color. This is a commonly used coating method in European and American countries, that is, the wood is colored with a water-based color paste on the treated substrate, and then polished and topped Paint, and then apply transparent topcoat, the basic process flow is: sanding-primer-sanding-base coloring-second primer-sanding-surface repair color-top paint but the open paint is too dependent on The texture of the original wood substrate is relatively strict and demanding in terms of material selection.

Open lacquered wood door purchase skills
1. Look at the appearance (lacquer and veneer)
The high-quality open lacquered wooden door has a full and smooth paint surface, rich and natural, and the paint film has good transparency. The texture of the surface material is clear and realistic, and the physical properties of the appearance are at a glance. There are many ripples and particles, the transparency of the paint film is poor, the surface texture is fuzzy, and the appearance of the wood is difficult to distinguish.
The reason for the low-quality open-lacquered wooden door is that, on the one hand, the paint selected by the manufacturer is of poor quality, and the craftsmanship and equipment are inadequate; on the other hand, the veneer used has many flaws, so the transparency of the coating is deliberately reduced to cover the surface.

Compared with several open lacquered wooden doors of the same specification and the same surface layer material, the open lacquered wooden door with too light weight can hardly be said to be a high-quality open lacquered wooden door, because the core material used is mostly softer (Such as poplar), the pipes and pores in the wood are relatively large; or the core material inside is too small, making the open lacquered wooden door not strong enough. This kind of open lacquered wooden door has poor strength and impact resistance, and has no sound insulation effect. it is good.
3. Look at the joints of veneer or solid wood
The veneer or solid wood splicing of high-quality open lacquered wooden doors are processed finely, and no bonding traces can be seen, while the veneer or solid wood of low-quality open lacquered wooden doors is rougher, and the splices are more obvious, and even cracks and dislocations appear.

High-quality open lacquered wooden doors have strict requirements on material selection, process control and factory inspection. The finished open lacquered wooden doors have a flat and straight surface and a perfect appearance after installation. Inferior open lacquered wooden doors have low requirements on materials, processes and inspections. The degree of warpage is large, and it is obvious that the open lacquered wooden door cannot be aligned with the door frame after installation.
