Acrylic bonding is the acrylic booth exhibition processing a very critical process, how to show the acrylic clear and transparent features, reflecting the value of acrylic exhibition booth, the maximum increase in the quality of plexiglass acrylic products and taste, bonding technology To play a pivotal role.

Acrylic bonding is mainly affected by two aspects, one is the applicability of the adhesive itself; the second is the bonding skills.

At present domestic and foreign markets have a lot of glue, mainly divided into two kinds, one is two components, such as Wan Nengjiao, epoxy resin; there is a single component, such as CCl3 (chloroform). In general, a two-component adhesive is bonded by a curing reaction, and a one-component adhesive is a solvent that is finally volatilized to achieve adhesion.

Two-component adhesive is characterized by better bonding effect, no bubbles after bonding, no white, high strength. Disadvantages for the operation of complex, difficult, curing time is long, slow, difficult to adapt to the requirements of mass production. The general characteristics of the one-component adhesive is faster, to meet the requirements of production of bulk products, the disadvantage of the adhesive products are easy to produce bubbles, easy to white, poor weather resistance, which directly affect the acrylic booth exhibition External appearance and product quality, therefore, in the acrylic booth exhibition processing, how to choose the right adhesive, improve the grade and grade of acrylic products, bonding process must first solve a big problem.

The following is the bonding skills:

1, docking: the two need to dock the acrylic plate level on the operating platform, close, and in the bottom of a sticky tape, leaving a gap of not more than 0.3mm wide to prepare the coating adhesive. With a syringe to the adhesive from one side slowly and slowly from the gap into the until all filled, to be completely cured after the tape can be removed.

2, facade bonding: facade bonding is the most widely used a bonding technology, in the production of various acrylic IT electronic digital exhibition booth products are widely used. First, wipe the surface to be wiped clean. It is best to use the mold to achieve the bonding, so that the adhesive does not shake, help to improve the quality of bonding. The thickness of 3mm plexiglass plate bonding, can be pad into the fine wire, the use of capillary action to complete the bonding, before the curing agent in the extraction of metal wire, or can be used adhesive tape, and then paste the adhesive method of bonding The

3, the slope of the adhesive: adhesive slope must be used 90o angle, etc., in order to prevent the displacement of the sticky face. Binder the adhesive should be uniform and slow. To be completely cured before they can be removed by the mold.

4, surface bonding: plane bonding is a relatively special bonding method. First, the surface will be wiped clean, and placed horizontally, in the above note the amount of adhesive. Place the other side of the acrylic plate obliquely into contact with the adhesive on the acrylic plate, and then evenly slow down, from the side of the bubble out to complete the bonding. Acrylic processing adhesives can erode the surface of acrylic panels and leave traces that are difficult to eliminate, so they can be used to protect areas that do not need to be adhered. Grease, dust or pores can prevent the coating of the adhesive evenly and leave the bubbles. Too much use of the adhesive will cause the adhesive to shrink into the air. Direct hair will make the edge of the adhesive surface due to the evaporation of the adhesive and white. Indoor humidity, temperature, etc. have a direct impact on the adhesion of acrylic panels.
