Know more about reconstituted wood
Reconstituted wood The production process mainly includes log debarking and cutting, log fiberization, phenolic resin impregnation, drying before impregnation and paving after impregnation, forming, etc. . According to the restructuring wood molding process, it can be divided into: cold pressing and hot curing process and hot pressing process.
When peeling and cutting fast-growing logs, the peeling and cutting process should be designed according to the wood texture and product performance requirements. Because the fast-growing artificial wood has the disadvantages of more lateral organization, more knots, soft materials and higher growth stress, it is possible to learn the defibrillation of veneer from the controllable bamboo fiber separation technology , And adjust the decomposition machine according to the characteristics of the wood. The number of times of reorganized wood tooth gap and disintegration, the veneer prepared by this technology has a more regular shape, the reorganized wood fiber does not break and the thickness is uniform. Most of the fast-growing wood veneers will have different degrees of point or line cracks on the surface after decomposition, making it more conducive to the adhesion and penetration of moisture. Or using fiber treatment technology can also achieve the effect of increasing the surface area and improving the quality of recycled wood. Dyed veneer, furniture leather also pay attention to this aspect.
Technology wood manufacturers remind you that the drying of reconstituted wood before impregnation usually adopts a combination of air drying and conventional drying, in order to control the moisture content at a certain level , Please make the immersion of the veneer more even. The drying after immersion usually adopts a mesh belt dryer. In order to avoid curing of the adhesive, the drying temperature should not be too high.
After the hot pressing process of the blank assembly method is impregnated and dried, the reconstituted wood veneer is laid along the wood grain direction, which helps to maintain the uniformity of the overall density of the slab and improve the utilization rate of recycled wood.
Technology wood manufacturers tell you that although the cold-pressing heat curing process has higher production efficiency and lower energy consumption, it is easy to keep the adhesive at low temperature for a long time due to the slow heating speed Carry out pre-curing, so that the performance of the product decreases and becomes unstable. The hot pressing process compensates for the defects of the cold pressing and heat curing process to a certain extent. The temperature rise rate is very fast, but it also has disadvantages such as high energy consumption.
