Problems solved by technology

[0002] Furniture is an essential item for every family, and wooden furniture occupies a large proportion. Due to innate factors, the surface of the furniture has a large number of cracks, insect holes, etc., and it is caused by insufficient drying, splicing, and polishing techniques in the later production. The surface of the furniture is uneven, which affects the appearance and service life of the furniture
[0003] At present, paints are generally painted on the surface of wooden furniture to improve the aesthetics of the furniture and enhance the service life of the furniture. However, the dispersion of traditional paints is poor, and the leveling property cannot meet the needs and cannot meet the needs.
