UV board manufacturers on the use of UV board materials

UV board manufacturers about UV board material Woodworking board (commonly known as big core board) is a plywood with a solid wood core. Its vertical (differentiated by the direction of the core board) has poor flexural and compressive strength, but its transverse flexural and compressive strength is relatively high. At present, most of the market is solid, glued, double-sided sanding, five-layer blockboard, which is one of the most commonly used boards in decoration.

advantage:

A. Blockboard has good screw holding power, high strength, strong quality, sound absorption, heat insulation, etc. The blockboard has a low moisture content, between 10% and 13%, and is easy to process. It is used for furniture, doors and windows, and Covers, partitions, false walls, heating covers, curtain boxes, etc., are the most versatile.

B. Because the interior is made of solid wood strips, the requirements for processing equipment are not high, which is convenient for on-site construction

shortcoming:

A. Because wood board uses a large amount of urea-formaldehyde glue in the production process, the formaldehyde emission is generally high, and the environmental protection standard is generally low. This is why most wood board tastes pungent.

B. At present, most of the wood board on the market cut corners during the production, and the gaps are large when splicing solid wood strips, and there are cavities in the board. If nails are nailed in the gaps, there is basically no nail-holding power.

C. The solid wood strips inside the wood board are longitudinally spliced, so the vertical bending and compressive strength is poor, and long-term stress will cause obvious lateral deformation of the board.

D. The solid wood strips inside the wood board have different materials and different densities. After a simple drying process, they are easy to warp and deform; the structure is distorted and deformed, which affects the appearance and use effect.

E. Because the surface of wood board is relatively rough, a lot of glue or paint is usually used when processing the surface at the woodworking site. Therefore, the furniture made from this board is extremely environmentally friendly. This is the main reason why the smell is very irritating during decoration. The reason is that such on-site furniture is the culprit for carcinogenesis and gene mutation, and it is very harmful to the human body.
