Integration timber

Integration timber is a large format, large-sized solid wood panel made from high-quality solid wood sawn timber as raw material, which is processed to remove wood defects (knots, decay, cracks, etc.), small pieces of wood are processed into standard wooden strips, and then connected by finger tenons, glued and pressed, and sandblasted to a fixed thickness.

Production process

The production process of integrated materials determines their performance stability, and the complete process is as follows:

Raw material screening and processing: Select solid wood sawn timber such as pine, oak, birch, fir, walnut, etc., and remove defects such as decay, insect infestation, and knots; Perform drying treatment to control the moisture content of the wood at 8%~12% (suitable for indoor use environment) to prevent subsequent deformation.

Processing of wooden strips: cutting dried wood into equal width and thickness specification wooden strips; Perform finger tenon processing on both ends of the wooden strip (forming tenon heads similar to finger interlocking) to increase the joint contact area and improve the connection strength.

Glue application and splicing: Apply environmentally friendly adhesive (commonly water-based polyurethane adhesive, modified urea formaldehyde adhesive) evenly at the tenon joint, and splice the wooden strips together through the tenon joint to form a continuous board blank.

Pressure curing: Place the spliced blanks into a cold press or hot press machine and apply pressure to tightly bond the finger joints; According to the type of adhesive, control the pressure (usually 0.8~1.2MPa) and curing time to ensure complete curing of the adhesive layer.

Thickness determination and sanding: Cut the cured board to ensure uniform thickness; Through multiple sanding processes, the surface is made smooth and even, meeting the requirements for finishing or direct use.

Inspection and grading: Check the splicing quality, moisture content, appearance defects, etc. of the board, and classify them according to the grade (excellent product, first-class product, qualified product).

Material Classification

The material of integrated wood mainly depends on the solid wood raw materials used, and is commonly classified as follows:

Classified by Wood Type

Cork integrated material: made from pine (white pine, red pine, camphor pine), fir, poplar and other raw materials, with a light texture, easy processing, and low cost, suitable for making cabinets, backboards, and mid-range furniture.

Hardwood laminated timber: made from oak, birch, walnut, cherry wood, and water chestnut as raw materials, with a hard texture, beautiful texture, and high strength, suitable for making high-end furniture door panels, tabletops, and decorative lines.

Divided by splicing method

Finger jointed laminated timber: The most common method is to use finger tenon joints, which have high strength and can achieve infinite length splicing.

Flat jointed laminated timber: The two ends of the wooden strips are directly connected, with a simple process, but the strength is lower than that of finger joints, and it is mostly used in non load bearing parts.

Classified by adhesive type

Adhesive composite material: a conventional product that uses adhesive for splicing, with high adhesive strength and good stability.

Glueless laminated timber: a high-end product that uses the fiber mesh or physical extrusion splicing of the wood itself, with extremely high environmental protection level, but the production process is complex and the cost is high.

Performance Characteristics

Retain natural wood characteristics: with the natural texture, texture, and environmental friendliness of solid wood, the decorative effect is natural and warm; It can undergo secondary processing such as painting, dyeing, and veneering.

Good dimensional stability: Through reasonable splicing methods and moisture content control, the defects of natural solid wood that are prone to deformation and cracking are overcome, and large panel materials can also maintain stability.

Excellent strength performance: The tenon joint increases the bonding area, and the longitudinal strength can approach or even exceed that of natural solid wood; The overall mechanical performance is uniform and the load-bearing capacity is good.

Controllable environmental performance: High quality composite materials use E0 and ENF environmentally friendly adhesives, with extremely low formaldehyde emissions; Non adhesive composite materials can achieve zero formaldehyde release, meeting high-end environmental protection needs.

High utilization rate of wood: Splicing small pieces of wood into large-sized boards reduces wood waste, conforms to the concept of environmental protection and energy conservation, and reduces the cost of using large-diameter solid wood.

Application scenarios

Furniture manufacturing: high-end solid wood furniture cabinets, door panels, tabletops, chair surfaces, etc., such as wardrobes, cabinets, dining tables, bed frames, etc; It can also be used to make children's furniture (with high environmental requirements).

Indoor decoration: wall decorative panels, ceilings, door frames, window frames, decorative lines, etc., create a natural and warm spatial atmosphere; It can also be used to make stair treads and handrails.

Customized Home Furnishings: Cabinet panels, open bookshelves, display cabinets, etc. in whole house customization, balancing environmental friendliness and aesthetics.

Wooden structure buildings: beams, columns, wall panels, roof panels, etc. of lightweight wooden structure buildings, some outdoor composite materials (treated with anti-corrosion) can be used for terrace floors and fences.

Crafts and musical instruments: small crafts, wooden carved bases, as well as parts such as the body and keys of some musical instruments (requiring uniform material and good stability).
