Production process of continuous artificial board production line

Abstract

The invention relates to a continuous artificial board production process belonging to the field of manufacturing of artificial boards. The production process of a continuous artificial board production line is characterized by comprising the steps of pre-spreading a base support layer which is equal to a plate blank in width or is slightly wider than the plate blank on a spreading belt of the artificial plate production line, wherein the base support layer adopts a layer of thin paper, or a layer of hot melt adhesive film or a layer of special plastic thin film or tree bark, is integrally formed or is formed by splicing a plurality of pieces of paper or films, and is subjected to gum dipping or release agent spraying; spreading by a spreading section of the belt of the production line, and prepressing by a prepressing machine, wherein the base support layer and the plate blank have certain binding strength; then carrying out hot pressing by a pressing machine to complete the production of the artificial plate finally. According to the production process, the problems of material dropping and steel belt sticking in the production process can be solved, the production cost is lowered greatly, the product quality is stable, one-time forming of the plate can be realized, and finished plates such as laminated boards, veneers and floors can be laminated once.

Description

technical field [0001] The invention relates to a continuous production line of wood-based panels, in particular to a production process of a continuous production line of wood-based panels. Background technique [0002] With the development of society, the requirements for environmental protection are getting higher and higher, and people are increasingly hoping to use non-toxic and formaldehyde-free household products. This requires wood-based panel manufacturers to provide wood-based panel products with higher environmental quality and larger scale, such as wood-based panels produced by more environmentally friendly glue such as low molar ratio UF glue, MUF or MDI glue. Due to the low molar ratio of these glues, the low initial viscosity of the glue, and the low strength of the slab, problems such as chipping, lower surface material drop, and steel strip sticking will occur in the industrial production process, resulting in various quality problems, and it is not suitable...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a production process of a continuous wood-based panel production line, which solves the problems of edge chipping, lower surface material drop, and steel strip sticking in the production process of the current wood-based panel continuous production line due to the low initial viscosity of the glue. , thus leading to defects in quality problems; solve the technical problems of producing veneers, veneers or floors at one time on the continuous production line of wood-based panels, and without the production of pre-cured layers, which can reduce production costs and achieve energy saving and environmental protection
