The large core board, also known as blockboard, is a versatile wood product commonly used in home decoration. It is manufactured by cutting logs into strips, splicing them together to form a core, and then covering the surface with different materials. Typically, it has a five-layer structure, making it strong and durable. This type of board is essential for wall and ceiling finishes, as well as for fine woodworking projects.
Blockboards are widely used in furniture manufacturing and as a structural frame for doors and windows. The surface material can vary, such as three-ply or five-ply boards, depending on the number of layers. Additionally, they can be classified based on the type of wood used, including species like Liuye, Eucalyptus, and Teak. High-quality blockboards have a smooth, even surface that resists warping and deformation. They can also be sanded easily to achieve the desired finish.
There are two main types of blockboards: one-side and two-side. The two-side boards are often used for decorative purposes, especially in key areas like furniture panels and door frames. When selecting blockboards, it's important to consider their quality, which is typically categorized as "excellent," "first-class," or "qualified." Some companies may use internal grading systems such as A, AA, or AAA, but these are not recognized by national standards and are not officially allowed in the market.
There are various types of wood core boards available, including poplar, birch, pine, and paulownia. Poplar and birch are considered the best options due to their dense texture, strong nail-holding ability, and resistance to warping. In contrast, paulownia has a very light and soft texture, which makes it absorb more moisture and less suitable for long-term use. Once dried, it tends to shrink and deform easily.
Hardwoods, while strong, are difficult to press and may not bond well during the splicing process. They often have poor nail-holding power and are more prone to deformation. Therefore, when choosing a blockboard, it's crucial to evaluate both the type of wood and the quality of the final product to ensure it meets the requirements of your project. Whether for furniture, cabinetry, or structural applications, understanding the characteristics of different blockboards can help you make an informed decision.
