What kind of wood board is formaldehyde-free? What is the material of blockboard?

Blockboard has good screw holding power, high strength, and has the characteristics of hardness, sound absorption, and heat insulation. It also has low moisture content, is easy to process, and has a wide range of uses. The characteristics of blockboard are mainly determined by the core board structure. It is usually used in furniture manufacturing, sewing machine tables, carriages, ships, and other production and construction industries. Many friends have asked what kind of blockboard is formaldehyde-free, so let's take a detailed look at the introduction of Encyclopedia Knowledge Network.

What kind of wood board is formaldehyde-free

During the production process of boards, glue is required, and glue generally contains formaldehyde, so generally boards contain formaldehyde. Ketian water-based boards use water-based adhesives instead of traditional urea-formaldehyde glues, but during the production and transportation process, they are inevitably exposed to formaldehyde, so strictly speaking, there are no truly formaldehyde-free boards, only more environmentally friendly boards.

What is the blockboard used for?

Uses of blockboard: furniture, doors, windows and frames, partitions, false walls, radiator covers, curtain boxes, door frames, etc.

Blockboard, commonly known as core board, wood core board, woodworking board, is made of two veneers glued together. The total thickness of the veneers glued on both sides of the blockboard shall not be less than 3 mm. The corner defects of various blockboards shall not exceed 5 mm in width within the nominal width and shall not exceed 20 mm in length. The middle wood board is made of high-quality natural wood boards that are heat-treated and processed into wood strips of certain specifications, which are spliced ​​by a boarding machine. The spliced ​​wood boards are covered with two layers of high-quality veneers on both sides, and then glued and pressed by cold and hot presses.

What is the material of blockboard?

Blockboard refers to a special type of plywood made by gluing and pressing wood strips or hollow boards as the core, and covering two or more layers of plywood on both sides. The characteristics of blockboard are mainly determined by the core structure. It is widely used in furniture manufacturing, sewing machine tables, carriages, ships, etc. and in the construction industry.

Blockboard has good screw holding force, high strength, and has the characteristics of being solid, sound absorbing, and heat insulating. It also has a low moisture content, is easy to process, and has a wide range of uses.
