What are the common methods for surface treatment of plywood?

The common methods for surface treatment of plywood include planing, sanding, and scraping. ‌
Planing method: The uneven parts of the plywood surface are cut off by a machine to achieve a smooth and even surface. This method is suitable for treating plywood surfaces with high roughness.
Sanding method: By grinding sandpaper or grinding heads on the surface of plywood, the surface roughness and unevenness are eliminated to achieve a smooth and polished effect. This method is suitable for situations where precise surface treatment is required.
Scratching method: By using certain machinery and equipment to scrape off the hair on the surface of plywood, a smooth surface effect is achieved. This method is suitable for situations where there are many fine hairs on the surface of plywood.
In addition, surface treatment of plywood can also be carried out through the following methods:
Moisture proof treatment: Improve the moisture resistance of plywood during storage, transportation, and construction sites.
Anti corrosion treatment: reduces the risk of mold growth and cyanosis.
Flame retardant treatment: Improve the fire rating of plywood.
Painting: Use fully colored opaque coatings, semi transparent coloring agents, or clear varnish.
These methods can effectively improve the appearance quality, service life, and processing performance of plywood, making it more widely used in fields such as construction and furniture.
