How Do Acrylic Products Stick

- Jan 03, 2018-

Acrylic products bonding is an acrylic processing in a crucial process in the link, how to show the characteristics of clear and transparent organic glass, acrylic tobacco packaging value to arts and crafts, the maximum enhance the grade of the acrylic handicraft and savour, bonding technology has played a pivotal role.

The adhesion of the organic glass plate is mainly affected by two aspects, one is the applicability of the adhesive itself.

Two is the technique of adhesion.

There are many adhesives in domestic and foreign markets. There are two main types, one is double component, such as the universal glue and epoxy resin.

There is also a single group, such as CHCl3 (chloroform).

In general, the adhesives of the bicomponent are realized by curing reaction, and the adhesive is the final volatilization of the solvent.

The two component adhesives are characterized by good adhesion and no bubble, white and strong strength after bonding.

The disadvantages are complex, difficult, long curing time, slow speed, difficult to adapt to mass production requirements.

While one-component adhesive is characterized by fast and can meet the technological requirements of batch production, the disadvantage is that after the adhesive products are prone to bubbles, prone to white, poor weather resistance, which directly affect the outside of the organic glass is beautiful and the quality of the products, therefore, in the machining process of organic glass products, how to choose the suitable adhesive, organic glass products grade and level, is in the bonding process must first solve a big problem.

In addition, the technique of adhesion is also very important. Here are some of our common adhesion techniques, and briefly analyze their actual operating experience.

1. Docking: place the two pieces of organic glass plates on the operating platform, close together, and glue a piece of adhesive tape at the bottom, leaving a gap of not more than 0.3mm wide to prepare the adhesive.

Use the syringe to inject the adhesive from the side evenly and slowly from the slit, until the whole filling is fully cured, then remove the adhesive tape.

2. Facades: the facade is adhered to the most widely used adhesion technology and is widely used in the production of various organic glass IT digital display shelves.

The surface that should be adhered to should be wiped clean first.

It is better to use die to achieve adhesion, so that the adhesion is not sloshing, which can improve the quality of adhesion.

Organic glass adhesive thickness is 3 mm, pad into fine wire, using capillary action complete bonding, drawn wire before the adhesive curing, or can use adhesive tape, and adhesive coating adhesive method.

3. Inclined surface adhesion: it is necessary to use the 90 degree Angle to avoid the displacement of the adherent surface.

The adhesive should be uniform and slow.

The mold can be removed when completely cured.

4. Surface adhesion: plane bonding is a special kind of bonding method.

First, the adhesive surfaces will be cleaned and placed horizontally, with a proper amount of adhesive.

On the side of the other piece of organic glass plate, contact the organic glass plate with the adhesive, and then put it down uniformly and slowly, and then push the bubble out and finish the adhesive.

The organic glass adhesive can erode the surface of the plexiglass and leave a trace that is difficult to remove, so you can use the adhesive tape method to protect the area that does not need to be glued.

Grease, dust, or stomata can interfere with the uniform coating of adhesives and leave bubbles.

Too little use of adhesives can bring the glue into the air when it contracts.

A direct blow will cause the edge of the adhesive to be whitened by the volatilization of the adhesive.

Indoor humidity, temperature and so on have a direct effect on the adhesion of organic glass plates.
