open paint what are the advantages and disadvantages of wooden doors?
1. Definition of open paint
open paint (mainly nitrocellulose lacquer) is a finishing process that completely reveals the pipe holes on the wood surface. Its main component is polyurethane (PU), with small concentration, showing obvious wood holes and clear texture, the paint coating amount is small, Matt, and the natural texture is strong, which can be repaired twice. However, it has high cost and high requirements on spraying technology, which requires six or seven times or even more than ten times.
2. Advantages and disadvantages of open paint
open paint refers to being able to see the natural characteristics of wood grain, just changing the color. This is a common finishing method in European and American countries, that is, coloring the wood with pigment dispersion on the processed substrate, then polishing, primer and then transparent finish paint. The basic process is as follows: polishing -- Primer -- polishing -- bottom coloring -- second degree primer -- polishing -- surface embellishing -- topcoat but open paint is excessively dependent on the texture of the original wood substrate, so it is relatively strict and harsh in material selection, therefore, open paint is a painting process that completely reveals the Brown holes on the surface of wood. It shows that the wood holes are obvious, the texture is clear, and the natural feeling is strong. However, it has high cost and high requirements for spraying technology, generally speaking, making open paint requires that the Brown holes of wood must be deep and obvious, such as oak and Manchurian ash.
Open paint wooden door shopping tips
1. Look at the appearance (paint surface and veneer)
high-quality open paint wooden door paint surface is full and smooth, rich and natural, the paint film transparency is good, the texture of the surface is clear and realistic, the physical properties of the appearance are clear, the inferior open paint wooden door paint film is dry and obscure, exposed paint, bubble, pinhole, there are many ripples, particles, etc., the transparency of the paint film is poor, the surface texture is vague, and the appearance of wood is obscure and difficult to distinguish.
The reason why the inferior open paint wooden doors are like this is, on the one hand, the paint quality selected by the manufacturer is poor, and the process and equipment are not closed; On the other hand, the wood skin selected by the manufacturer has many flaws, so the transparency of the coating is deliberately reduced, to cover sound knot, holes, decay, discoloration, cracks, indentation and other defects on the surface.

2. Weight (whether the weight is appropriate)
good open paint wooden doors should not be too light. Compared with open paint wooden doors with the same specifications and the same surface materials, it is hard to say that open paint wooden doors with too light weight are high quality open paint wooden doors, because the core material is mostly soft (such as poplar), the pipes and pores in the wood are relatively large; Or the core material inside is too small, making the open paint wooden door not strong enough, the strength and impact resistance of this open paint wooden door are relatively poor, and the sound insulation effect is not good.
3. Look at the veneer or solid wood splicing place
the veneer or solid wood splicing of high-quality open paint wooden doors is processed with fine processing, and no trace of combination can be seen. However, the veneer or solid wood splicing of inferior open paint wooden doors is rough, and the splicing is obvious, even cracking and dislocation occur.
4. Look at the flatness of open paint wooden doors
high-quality open paint wooden doors have strict requirements on material selection, process control and factory inspection. The surface of finished open paint wooden doors is flat and straight, and the appearance is perfect after installation. Inferior open paint wooden doors have strict requirements on materials, the requirements of process and inspection are very low, and the warpage of finished open paint wooden doors is relatively large. After installation, it can be obviously observed that open paint wooden doors and door frames cannot be aligned.
