Description

Technical Field

[0001] The invention belongs to the technical field of edge sealing equipment, and in particular relates to an edge sealing equipment for a wood product formaldehyde test specimen. Background Art

[0002] Formaldehyde emission is an important safety and environmental indicator for measuring the quality of wood products. It has always attracted the attention of consumers and the entire wood-based panel, flooring, and furniture industry. It is the parameter that consumers pay the most attention to when purchasing wood products. Many countries at home and abroad have made strict limit regulations on formaldehyde emission in the form of laws, regulations, and standards.

[0003] Wood products based on wood materials, such as plywood, particleboard, fiberboard, laminated wood, finger-jointed wood and blockboard, often emit formaldehyde to varying degrees during use, and this slow release takes a long time. For general wood-based panels, the formaldehyde released mainly comes from adhesives such as urea-formaldehyde resin and phenolic resin. In the process of detecting the amount of formaldehyde released from artificial boards and their products, it is often necessary to saw the artificial boards into test specimens of a certain size, and then seal the edges of the test specimens after sawing. For example, the Chinese standard GB18580 "Limits of Formaldehyde Emission from Artificial Boards and Their Products for Indoor Decoration and Renovation Materials" and GB / T17657 "Test Methods for Physical and Chemical Properties of Artificial Boards and Facing Boards" require that the test specimens be sealed with formaldehyde-free aluminum tape, and the ratio of the unsealed length L to the surface area of ​​the specimen is 1.5m / m 2 . For the test pieces with the size of 0.5m×0.5m, the unsealed length of each test piece is 0.75m. For the floor samples, one side of the test piece is sealed with aluminum foil, and all sides are sealed with aluminum foil. Other international formaldehyde emission testing standards for artificial boards and their products, such as: EU standard EN717-1, international standards ISO12460-1, ISO12460-3, American standards ASTM D 6007, ASTM D 5582, etc., all have clear requirements for the edge sealing of test pieces.

[0004] In the prior art, the self-adhesive aluminum foil is often manually sealed on the side of the test piece. However, the edge sealing accuracy of the test piece is poor, the edge sealing operation time is long, the work efficiency is low, and in the manual operation process, it is easy to appear outside the pasting, the aluminum foil is uneven, and even the test piece is scrapped due to mis-pasting or over-pasting, which not only affects the subsequent work, but also has a significant impact on the test results; in addition, the self-adhesive aluminum foil tape is thin and hard, and the operator is often easy to scratch his hands when pressing the edge sealing. Therefore, there is an urgent need for an edge sealing device for wooden formaldehyde test pieces that can solve the existing problems. Summary of the invention

[0005] The purpose of the present invention is to provide an edge sealing device for wood product formaldehyde test specimens in view of the deficiencies in the prior art. The device has high specimen edge sealing accuracy, is easy to operate, and has strong applicability.
