Cherry wood, walnut, eucalyptus... How much do you know about these wood species used as solid wood door wood? Glulam, finger joints... These seemingly unfamiliar terms are probably part of your solid wood door, and they directly affect the quality of your home. Therefore, before choosing a wooden door, it is helpful to first understand their general materials, which will help you choose a more suitable wooden door.
Cherry wood has imported domestically produced points
If you want to buy solid wood doors, the various names of wood on the market may make you faint. They are of various materials, and the scientific names and common names are mixed. It is not easy to distinguish them clearly. According to Wu Shengfu, director of the marketing department of the China National Forest Products Industry Association, wood used for wooden doors (which can be used as both solid wood and surface decorative materials) is Sapele, Pear, Teak, Cherry, Walnut, Maple. Wood, eucalyptus (eucalyptus, oak), ash, hemlock, southwest birch, pine, fir (all above are market names). Among them, cherry wood is imported and domestically produced, and its price is not the same. It is necessary to beware of the “stealing the columnâ€.
Cherry wood: Rosaceae, also known as the American black cherry. Mainly produced in North America, the main products are mainly in the United States. The core material is from deep red to light reddish brown. Wood has good bending properties, low hardness, medium strength and impact resistance. Selected logs can be used to make furniture and cabinet veneers, siding and glossy doors. Cherry wood is relatively expensive due to its beautiful texture and imported large diameter material.
At the same time, there is a kind of wood produced in southern China, Myanmar, Laos - southwestern birch, the texture is between cherry wood and Sapele, known as the domestic cherry wood. The wood has a high hardness and quality, a light brown color, a beautiful wood grain and easy processing. Because of its beautiful cherry wood pattern, its cost is lower than that of imported cherry wood. However, some untrustworthy merchants in the market may be “sweetenedâ€. It is recommended that consumers ask clearly when purchasing, and let the salesperson confirm that they are imported cherry wood and put it into the contract.
Glulam is better than natural wood
In the minds of many consumers, if you choose solid wood doors, natural wood is definitely better, environmentally friendly and beautiful. In fact, solid wood doors have gradually become unrealistic pursuits. The reason is that the current situation of raw material supply does not allow the use of solid wood panels in large quantities, the use of tantalum to produce solid wood doors, the second is that solid wood panels are prone to cracking and deformation, and the third is that woodworking with a combination of tantalum is not easily integrated by modern processing techniques. Wu Shengfu believes that the laminated timber retains the aesthetics of natural wood and has an advantage in physical properties.
According to reports, the glulam (glued wood) is a material obtained by laminating sheets, small squares, etc., which are substantially parallel in the direction of fibers, in the length, width and thickness directions. According to reports, the laminated timber is made of the short size of the solid wood to the required size and shape, so that the small material can be used greatly and the inferior material is excellent. Eliminating wood defects such as knots and decay before gluing can produce materials with few defects. When fitting the board, the wood defects can be dispersed even if there is wood defect. If there is a special need, the plate can be pre-treated with different drugs before gluing. Even if it is long or large, it can have enough chemicals inside to make the material have excellent anti-corrosion, fire resistance and insect resistance.
Compared with natural wood, the laminated wood does not change the structure and characteristics of the wood. It is still a natural substrate, retaining the texture of the natural wood and the appearance is beautiful. From the point of view of physical and mechanical properties, the stability is good, cracking deformation is not easy to occur, and it is superior to natural solid wood in terms of material quality uniformity. In addition, since the raw materials are sufficiently dried, even in the case of large-section and long-sized materials, the moisture content of each part is uniform, and the cracking deformation is small compared with the natural solid wood.
Three methods to identify the board is good or bad
Finger joints are also one of the most important materials for solid wood doors. So what is the material? The finger joint material is made of sawn timber as raw material, which is made by finger pressing and glued and long. It is the length of the wood in the length direction. The finger joint material is made into a finger joint plate after being laterally widened.
The finger joint board is also divided into two sections: no knots and no knots. There are knots in the blink of an eye, no knots in the blink of an eye, and more beautiful. How should consumers identify the quality of the fingerboard? The experts taught three simple and easy methods: First, look at the core annual rings. The finger joints are mostly made of fir and pine wood. The annual rings are more obvious. The smaller the annual rings, the longer the trees are, and the better the materials are. Second, look at the gums. The gums of the finger joint plate are divided into a horizontal type and a vertical type. It is also said that the gums are divided into a dark tooth and a bright tooth, and the horizontal type is a dark tooth. Because the bright teeth are more likely to appear uneven after painting, the dark teeth are better, of course, the processing of the dark teeth is more difficult. Third, look at the hardness of wood. Wood-hard finger joints are preferred because the hard deformation of the material is relatively small and the pattern is more aesthetically pleasing.
