The bonding of acrylic products is a key process in acrylic processing. How to show the clear and transparent characteristics of organic glass, reflect the value of acrylic tobacco and wine packaging crafts, and maximize the level and taste of acrylic crafts, the bonding technology plays an important role.
The bonding of plexiglass board is mainly affected by two aspects, one is the applicability of the adhesive itself, the other is the bonding skills.
There are many adhesives in the domestic and foreign markets, mainly including two types: one is two-component, such as universal glue and epoxy resin; the other is single component, such as CHCl3 (chloroform). Generally speaking, the two-component adhesive realizes the bonding through the curing reaction, and the single component adhesive realizes the bonding by the final volatilization of a solvent.
The two-component adhesive is characterized by good bonding effect, no bubble, no whitening and high strength after bonding. The disadvantages are complex operation, difficulty, long curing time, slow speed, and difficult to adapt to the requirements of mass production. The general single component adhesive is characterized by fast speed, which can meet the process requirements of mass production. The disadvantage is that the bonded products are easy to produce bubbles, easy to whiten, and poor weather resistance, which directly affects the appearance and product quality of plexiglass products. Therefore, in the processing of plexiglass products, how to select the appropriate adhesive to improve the quality of plexiglass products Grade and grade is a big problem that must be solved first in the bonding process.
