Why do bathroom cabinets shrink and wet?

Why do bathroom cabinets shrink and wet? Many people choose to install solid wood bathroom cabinets. In daily use, we often encounter problems with the shrinking and drying of solid wood bathroom cabinets. The causes and solutions of the problems are plagued by many people. This article will introduce you to this topic, so that you have a correct understanding in life, let's take a look at it with Xiaobian.

Why do bathroom cabinets shrink and wet? It is said that many people do not know

The finest solid wood bathroom cabinets will use solid wood as the main material, and the solid wood material will inevitably have the characteristics of dry shrinkage and swelling. In a certain range, with the change of the moisture content of the wood itself, the size and shape of the wood itself will change. The shrinkage and swelling of the wood is different in different directions, the chord direction is the largest, the second is the radial direction, and the smallest is the longitudinal direction. In general, the chord direction is twice the radial direction, and the chord direction and the radial direction are several tens to hundreds of times in the longitudinal direction.

The shrinkage and swelling of wood varies with tree species and density. Dry shrinkage is an inherent property of wood, which affects the processing and utilization of wood to a large extent. Due to the shrinkage and swelling of the wood, the warping and cracking of the wood are often caused. This should be avoided as much as possible in the processing and utilization of wood.

Control the moisture content of the wood by artificial drying, so that the moisture content of the wood is close to or slightly lower than 2% - 3% of the local equilibrium moisture content, so that the mailbox can reduce the shrinkage and swelling of the wood. This is also the main method for many bathroom cabinet manufacturers to dry wood, the wood moisture in the production of bathroom cabinets is controlled within 8% - 12%.

The size of the diameter-cutting plate is better than that of the string cutting board. However, the production rate of the diameter cutting board is relatively low, the cost is relatively high, and the processing technology is complicated, so the diameter cutting board is rarely used in the bathroom cabinet industry.

The use of mechanical suppression to improve the dimensional stability of the wood by its dry shrinkage anisotropy is a good example of the layered wood texture, which makes the wood contain each other during shrinkage, effectively reducing Dry shrinking to improve stability.

The use of hydrophobic materials to seal the wood using chemicals or paint Deng to treat the surface of the wood radially, to isolate the wood from the environment, the general bathroom cabinet manufacturers will use the end of the treasure to seal the wood of the bathroom cabinet, the wood and the environment Open, so that moisture can not flow freely. The stability of wood after paint treatment is much greater than that of untreated.
