Laminated veneer lumber is mainly made of wood, with simple workmanship, low chemical composition, strong environmental protection, and has a lot of satisfaction in the use process. The production of laminated veneer lumber in China is basically manual, with low production efficiency and unstable quality. With the expansion of demand, manual production of European standard quality laminated lumber has been difficult to meet the requirements, and the mechanization of laminated veneer lumber production has been realized. Imminent. At the same time, the General Office of the State Council forwarded the notice from the Reform Commission and other departments on accelerating the promotion of timber conservation and substitution opinions, clearly requesting all industries to accelerate the implementation of timber conservation and substitution technologies, and make green products. Laminated veneer lumber is widely used in warehouses, warehousing, logistics, food, beverages, beer, medicine, textiles, automobile manufacturing, electronic appliances, hardware machinery, logistics centers, etc.
To check the quality of laminated veneer lumber, we must identify it from the following four aspects:
1. Check whether the material of the laminated veneer panel is made of wood. It is best to use imported eucalyptus veneer;
Second, check the appearance of laminated veneer lumber to see if the edges are straight, the wall thickness is substantial, the size is standardized, and the color is consistent, and to ensure that the laminated veneer does not have problems such as splicing, wormholes, and defects.
3. Check whether the inner sandwich material of the laminated veneer lumber has cracking, bubbling, and whether the core board has large gaps.
4. Check whether the grade of laminated veneer lumber meets the standard, and avoid low-grade boards impersonating high-grade boards;
The standardization of laminated veneer lumber can bring huge social and economic benefits. The standardization rate of laminated veneer lumber in my country is much lower than that of developed countries. Therefore, we should vigorously promote the production of standardized laminated veneer lumber and accelerate the construction of supporting standards for standardized laminated veneer lumber. Standardized laminated veneer lumber can be reused multiple times, making the cost of using laminated veneer less than one-tenth of that of disposable boards. It can also increase the volume utilization rate of loading and inventory, and improve logistics efficiency. Significantly reduce logistics costs.
