Several common bonding process for acrylic products
Acrylic bonding technology is also very important, the following several of our common bonding process, a simple analysis of their actual operational experience.
1, docking: the two need to dock the plexiglass plate on the operating platform level, close, and stick a tape at the bottom, leaving a gap of not more than 0.3mm wide to prepare for the adhesive coating. With a syringe from the side of the adhesive evenly from the gap into the injection until all filled, to be completely cured after the tape can be removed.
2, facade bonding: Facade bonding is the most widely used adhesive technology, in the production of various plexiglass IT electronic digital display products are widely used. First, the surface to be bonded should be wiped clean. It is best to use the mold to achieve bonding, so that the adhesive does not shaking, help to improve the quality of bonding. The thickness of 3mm plexiglass plate bonding, can be padded into thin metal wire, the use of capillary action to complete the bonding, the adhesive before curing out of metal wire, or adhesive tape can be used, and then adhesive bonding method .
3, beveled adhesive: bonding slope must be used 90 degrees angle by the mold, in order to prevent the sticky surface shift. Apply adhesive should be uniform, slow. To be completely cured before removing 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 injection of the right amount of adhesive. The other piece of plexiglass plate side of the oblique contact with the adhesive coated plexiglass plate, and then evenly slow down, from one side of the bubble out to complete the bonding. Plexiglass adhesive can erode the surface of the plexiglass plate, and leave hard to eliminate the traces, so you can stick with adhesive tape to protect the site without bonding. Grease, dust, or stomata can prevent even coating of the adhesive from leaving bubbles. An excessively small amount of the adhesive may cause the adhesive to contract into the air. The direct blowing causes the edge of the adhesive surface to whiten due to the volatilization of the adhesive. Indoor humidity, temperature, and so on the plexiglass plate bonding has a direct impact.
