Embodiment Construction

[0098] The technological feature of the present invention is that each layer of veneer of the plywood is coated with glue on one side, and the shape and size of the veneer are not limited, and they can be overlapped with each other when forming blanks, so that each veneer can be connected with the adjacent The veneers can be glued together, which improves the bonding strength of the boards. The waste small pieces of veneers are used to reduce the diameter to 1.5 cubic meters of logs to produce 1 cubic meter of plywood formwork, which greatly improves the utilization rate of wood by 56%.

[0099] In order to make the surface of the template smooth, water-resistant and durable, the present invention pastes a layer of resin-impregnated paper mold on the base material of veneer glued plywood to make it smooth and durable.

[0100] The single-side gluing process has the following advantages:

[0101] The traditional double-sided gluing process produces plywood with odd-numbered lay...

Abstract

A method for producing the plywood with the wood plys whose one surface is coated by resin includes such steps as sawing log short, boiling in water, removing bark, spinning cutting, cutting fly, drying, ageing, coating resin on one surface of each ply, ageing, laminating, pre-pressing, trimming, hot pressing, trimming, sawing edge, sticking a paper immersed in resin, and classifying.

Description

Technical field: [0001] The invention relates to a production method of plywood, which belongs to the technical field of wood processing. technical background: [0002] Plywood is a kind of wood-based panel, and clear water formwork is a high-quality formwork made of plywood. It is a mold with smooth surface and high precision for concrete used in house construction. With the development of the construction industry and the improvement of building grades, the quality requirements for building formwork are getting higher and higher, and clear water formwork is the product that meets high-quality buildings. [0003] The gluing process of conventional plywood production is double-sided gluing, and the requirements for the veneers on the glued layer are whole sheets or straight-edge splicing, and end joints and lap joints are not allowed, especially for adjacent unglued veneers. Overlap joints are not allowed when slabs are assembled. If there is an overlap joint, there will b...
