A production process and equipment for anti-delamination and anti-seepage vertical plywood

Abstract

The invention discloses a production process and equipment for anti-delaminating anti-seepage vertical veneers. The process comprises the steps of cleaning, saw cutting, gluing, overturning, paving, hot pressing, sanding and recombining in sequence, and then the anti-delaminating anti-seepage vertical veneers are obtained. The production equipment for the anti-delaminating anti-seepage vertical veneers comprises an overturning mechanism used for achieving overturning and a pressing and edging mechanism. According to different strength, the upper surfaces and the lower surfaces of the vertical veneers as core boards need to be covered with GMT sheets, SFT sheets, LFT sheets, CFRT sheets and other enhancement layers of different strength, and the strength of the veneers is effectively improved. The veneers have the functions of seepage prevention and wear resistance at the same time. The application range of the veneers is effectively enlarged. The veneers arranged vertically are used as the core boards. The angle between the lamination gluing direction of single veneers and the thickness direction of the veneers is 90 degrees. The problems of delamination and cracking between single veneers are effectively solved. The cost is lowered by utilizing waste veneers. Reutilization of resources is realized. The production process and equipment have good market prospects. The equipment is simple in structure and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of boards, in particular to a production process and equipment for an anti-delamination and anti-seepage water vertical plywood. Background technique [0002] Plywood is widely used in the board industry because of its low manufacturing cost and high strength. Plywood is made of multi-layer veneers pressed by glue, so it contains a lot of glue, resulting in poor heat resistance and waterproof performance; As a result, the board cannot be used. At present, there is a technology in the market to apply waterproof paint on its surface to improve the water resistance. However, after a period of time, the board will still have moisture problems such as water seepage, which cannot be completely solved. Every year, a large amount of plywood is discarded due to problems such as moisture and cannot be reused, resulting in waste of resources. Contents of the invention [0003] Aiming at the deficiencies in the prio...
