The wood board (commonly known as the Big Core board) is the plywood with solid plank core, its vertical (with the core plate to differentiate) The flexural compressive strength is poor, but the transverse flexural pressure strength is higher. Now most of the market is solid, glue, double-sided sanding, five layers of blockboard, is currently decorated with one of the most commonly used plate.Chemical Sheet
Personal view: In fact, the quality of the wood board is good for the environmental coefficient is also guaranteed, but the cost is higher, plus the late paint and other processes, will be more or less an environmentally friendly products become less environmentally friendly. Fine wood Board grip screws good, high strength, with quality, sound absorption, insulation and other characteristics, Blockboard water content is not high, between 10%-13%, processing simple, for furniture, doors and windows and sets, partitions, false walls, heating cover, curtain box, etc., the most widely used.Chemical Sheet
Because of the heavy use of the urine aldehyde gum in the production process, the formaldehyde release is generally high, and the environmental standard is generally low, which is why most of the wood board smells pungent. Currently on the market most of the woodworking board production Jerry-building, in the splicing of solid wood bar when the gap is large, the plate internal cavity, if in the gap to nail, there is basically no grip nail force. The wood board inside the timber is longitudinal splicing, so the strength of the strong bending pressure is poor, long-term stress will lead to the plate obviously transverse deformation.Chemical Sheet
Wood plate inside the material is not the same, the density is different, only after simple drying treatment, easy to warping deformation, structure distortion, deformation, affect the appearance and use effect. Due to the rough surface of the wood board, therefore, woodworking site processing, in the surface of the treatment is usually used in large quantities of glue or paint, so this plate made of furniture is very environmentally friendly, this is why the decoration of the main reason for the taste is very stimulating, this kind of site-made furniture is carcinogenic and lead to gene mutation of the culprit, The damage to the human body is very big.Chemical Sheet
