The purpose and particularity of wood coating is clear
First, the purpose of wood coating:
1. Protection
HC Coating Network: Once the wood is coated, it is like wearing a beautiful coat, which isolates the direct contact between the wood and the outside air, moisture, sunlight, various liquids and various fungi, preventing the darkness of the wood itself. Decaying and tempering also alleviates the direct effect of external forces such as mechanical shock, so that wood products are not damaged quickly, thus prolonging the life of wood products and indirectly saving wood. For wood products made of inferior wood, due to the protection of the paint, its own defects (worm eyes, thrift, cracks, etc.) are also concealed, which improves the value of inferior materials to a certain extent and improves the utilization rate of wood.
When wood products are made of soft materials (such as pine, fir, etc.), due to their low surface hardness and poor wear resistance, external forces are more likely to cause surface damage. After painting (especially with a coating with better hardness), the surface hardness of the product can be improved to a certain extent, thereby reducing the damage of external force. The formation of a dense coating after coating can prevent the movement of moisture in the wood product due to changes in ambient temperature and humidity, thereby preventing the wood from expanding or shrinking and deforming and cracking. When the surface of the wood is painted, the coating protects the wood product from deformation due to changes in external humidity, minimizing damage.
The coated woodwork is also easy to clean and maintains long-term hygiene.
2, decorative effect
The painted wood products have a pleasant appearance, the surface is smooth and smooth, and has a moderate luster. At the same time, the inherent pattern of the wood is more clearly displayed after painting, which is rich in three-dimensional sense, so that the natural beauty of the wood is perfectly discharged. . For wood with dull shades (poplar, birch, etc.) and particleboard and MDF, different colors can be used to form paints of various colors and styles, as well as various forms such as cracks. .
The painting of wood products not only beautifies the appearance of wood products, but also enhances the added value of wood products, and also beautifies people's living space.
Second, the special characteristics of wood coating:
1. Wood has natural warmth and moderate softness.
And the unique material feel, in order to express the inherent characteristics and beauty of wood texture, wood coating is generally suitable for transparent coating.
2, a wide variety of wood, and has unique properties such as porosity, anisotropy, moisture absorption and dehydration, expansion and contraction, easy to decay and other shortcomings, these changes are easy to reduce the value and service life of wood products. To avoid the influence of so many unfavorable factors, it is necessary to show their natural beauty such as wood texture, texture, color and texture, which has many difficulties for painting.
3, due to the exhaustion of resources, it is impossible to use a piece of wood for the whole piece of furniture, but different wood splicing assembly, color and material texture are very different, in order to obtain a good coating effect, in addition to a deep understanding of the nature of wood and paint In addition, higher application requirements have been put forward for the application of various colored products such as coloring agents and fillers and the matching of various coating equipment.
4, from wood to finished products, painting can best reflect the beauty and value of wood. Therefore, in addition to a full understanding of the product's characteristics, uses and various coating methods, the physical properties, chemical composition, appearance and anatomy of wood should also be deeply understood, and the characteristics of various wood coatings should be recognized. Know that we can produce high quality products.
