For custom furniture, the board should be one of the most important parts. The quality of a board can be defined from four attributes: quiet zone strength, water absorption expansion rate, formaldehyde release, and screw-holding strength. Why are these four attributes so important? Next, I will explain it to you in detail:
1. Static bending strength
What is static intensity? To sum up in one sentence: Static bending strength is an important attribute that determines whether your cabinet will bend or even break during future use.
The static bending strength of the board is related to the raw material. Generally speaking, the physical properties of wood grown in alpine forest areas are more stable. If the growth period of the tree is too short, the static bending strength value will be low, so the optimal tree age is about 15-30 years. In addition, the production process can also have an important impact on the static bending strength of the board. Reasonable technology can make the board structure stable and difficult to warp and deform.
Of course, in fact, in addition to the static bending strength of the cabinet, the deformation of the shelves is also related to the span of the shelves. In order to pursue the so-called effect, some consumers require designers to make the span of some cabinet shelves particularly large. Whether it is The board will probably become curved in the future.
The span of the bookcase in this rendering will definitely bend in actual use. The picture is from the Internet and has been deleted.
2. Water expansion rate
I believe everyone can also know from the literal meaning that this attribute means that your cabinet is "moisture-proof or not".
But a point of view must be corrected here. No matter what type, brand or craftsmanship any board is, it is afraid of water! ! !
If you want cabinets that are not afraid of blisters, there are two ways to do it, one is brick/cement cabinets, and the other is integral stainless steel cabinets!
Therefore, for boards, moisture-proofing actually only ensures that they will not swell and deform under the relatively large air moisture content in the kitchen (there may be a small amount of water in the sink cabinet), which will affect the force balance of the countertop and the hinge holding force. All this is not only related to the water absorption expansion rate of the board, but also related to the edge sealing process after the board is cut.
It is recommended that you pay attention to two points when purchasing cabinets:
Whether the boards used in the cabinets meet the national water absorption expansion rate standards (less than 8%); take a rough look at the edge sealing process of the cabinet brand sample cabinet you purchased: observe whether the edge sealing is smooth, whether there is glue overflow, whether it falls off, etc.
