Surface artificial board surface paint spraying process

Abstract

The invention discloses a surface artificial board surface paint spraying process, which is carried out according to the following steps of (1) paint mixing; (2) color printing; (3) drying and primer adhesion; (4) paint curing; (5) first pass of finish spraying and coating; (6) second pass of finish spraying and coating; (7) paint leveling; (8) semi-curing; and (9) complete curing. A spraying curtain film of a spraying and coating machine is generated through the pressure of a diaphragm pump, the thickness is convenient to regulate, in addition, the distribution is uniform, the paint surface thickness is uniform, during spraying and coating, the highest conveying speed can reach 80m per minute, the surface paint of the wood board is uniform, and meanwhile, the coating thickness of the paint is also reduced. The surface artificial board surface paint spraying process has the advantages that paint films with uniform thickness and glossiness are formed on the surfaces of wood door products through spraying and coating, and in addition, the spraying and coating quality and the production efficiency are effectively improved through the surface artificial board surface paint spraying process.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a process of surface coating surface paint on artificial boards. Background technique [0002] Wood-based panel products are widely used in furniture manufacturing and interior decoration because of their large format, uniform material, not easy to deform, good physical and mechanical properties and mechanical processing properties, and have become a part of people's production and life. an important material. Wood-based panels are boards or molded products that use wood or other non-wood plants as raw materials, are separated into various unit materials by certain mechanical processing, and are glued with or without adhesives and other additives. Mainly include plywood, shaving (crumb) board and fiberboard and other three categories of products, wood-based panels can also improve the comprehensive utilization of wood, 1 cubic meter of wood-based panels can replace 3 to 5 cubic...

Problems solved by technology

The common problems of the coating process of the curtain machine are: uneven thickness of the coating film, difficult to control the thickness, pitting on the surface of the coating film, small circular pits on the surface of the coating film, small bubbles on the surface of the coating film, unstable coating film, and broken film , the coating film is "orange peel-like", the gloss of the paint film is uneven, etc.
