Description

Section bonding process with tight splicing

Technical Field

The invention relates to the technical field of profile processing, in particular to a profile bonding process with tight splicing.

Background

The processing and production popularity of the section bar is very high, and different processing methods and process flows are usually provided correspondingly in order to adapt to different products.

In the production of identification plates, a considerable number of profiles, the number of acrylic sheets being relatively large, also have to be used. The method generally comprises the steps of rough machining, cutting, polishing and the like of the acrylic plates, chamfering operation is carried out on the edge parts of the acrylic profiles according to the requirements of production drawings, and glue is coated at the chamfering positions of the two acrylic plates so as to realize bonding between the two acrylic plates.

However, in a long-term construction operation, a problem that strength and appearance are greatly affected occurs, that is, many bubbles with different sizes are easily generated on a chamfered surface coated with glue, and the reason for this is that flatness of the chamfered surface is not enough, and splicing between two acrylic plates is not tight enough, so that even if the glue seeps out from a seam, a gap cannot be completely filled, and the glue is too hard to dry, so that bubbles generated by "core wrapping" are generated.
