Acrylic is an important plastic polymer material developed earlier, which has good transparency, chemical stability and weather resistance, easy to dye, easy to process and beautiful appearance. How to show the clear and transparent characteristics of plexiglass and improve the grade and taste of acrylic crafts to the maximum extent, 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.
The following is a brief analysis of the practical operation experience of several common bonding processes.
1. Butt joint: place two PMMA Plates to be butt joint horizontally on the operation platform, close them, and stick a tape on the bottom, leaving a gap no more than 0.3mm wide for the application of adhesive. Use a syringe to inject the adhesive from one side evenly and slowly into the gap until it is fully filled, and then remove the adhesive tape after it is completely cured.
2. Facade bonding: facade bonding is the most widely used bonding technology, which is widely used in the production of various plexiglass it digital display products. The surface to be bonded shall be wiped clean first. It is better to use the profiling to achieve the bonding, so that the bonding material does not shake, which is conducive to improving the bonding quality. The plexiglass board with a thickness of 3mm can be bonded by inserting fine wire, and the capillary action can be used to complete the bonding. Before the adhesive solidifies, the wire can be pulled out, or the adhesive tape can be used, and then the adhesive can be applied.
3. Inclined plane bonding: the bonding inclined plane must use a 90 degree angle and other profiling models to prevent the displacement of the glued surface. The adhesive shall be applied evenly and slowly. The profiling can only be removed after complete curing.
4. Plane bonding: plane bonding is a special bonding method. First, wipe the surface to be pasted clean, and place it horizontally, and inject proper amount of adhesive on it. Place one side of the other plexiglass plate obliquely on the plexiglass plate which is coated with the adhesive, then put it down evenly and slowly, and drive out the bubbles from one side to complete the bonding.
