What are the bonding methods of pc board?

The PC sheets is resistant to weak acids. It is made of polycarbonate as the main component and adopts the co-extrusion technology CO-EXTRUSION. It shows that the PC board is resistant to neutral oil, not strong acid, not durable, and not resistant, and it needs to be coated with UV. Just work. But with high temperature resistance and good lighting effect, PC polycarbonate sheet (also known as polycarbonate hollow board, glass caplon board, PC hollow board) is processed by high-performance engineering plastics-polycarbonate (PC) resin It has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame resistance, anti-aging, etc. It is a high-tech, extremely excellent comprehensive performance, energy-saving and environmentally friendly plastic sheet, and it is currently widely used in the world. Building materials have advantages that other building decoration materials (such as glass, plexiglass, etc.) cannot match. 1. Butt joint: Place two plexiglass plates that need to be jointed horizontally on the operating platform, close them, and stick a tape on the bottom, leaving a gap not greater than 0.3mm wide for the application of adhesive. Use a syringe to inject the adhesive uniformly and slowly from one side into the gap until it is completely filled. After it is completely cured, remove the tape. 2. Facade bonding: Facade bonding is the most widely used bonding technology, which is widely used in the production of various plexiglass IT electronic digital display products. First, wipe clean the surface to be bonded. It is best to use a master mold to achieve bonding, so that the bonded object does not shake, which is beneficial to improve the quality of bonding. Plexiglass plates with a thickness of 3mm can be bonded with thin metal wires. The bonding can be completed by capillary action. The metal wires can be drawn out before the adhesive is cured, or adhesive tape and then adhesive can be used for bonding. .

3. Bevel bonding: The bonding bevel must use a 90-degree angle to prevent the displacement of the bonded surface. The adhesive should be applied evenly and slowly. After it is completely cured, the master can be removed. 4. Surface bonding: Plane bonding is a special bonding method. First, wipe the sticky surface clean and place it horizontally, and pour an appropriate amount of adhesive on it. Place one side of another plexiglass board diagonally in contact with the plexiglass board coated with the adhesive, and then lower it evenly and slowly, and drive out the bubbles from one side to complete the bonding. Plexiglass adhesive can corrode the surface of the plexiglass board and leave traces that are difficult to eliminate. Therefore, you can use a self-adhesive tape to protect the parts that do not need to be bonded. Grease, dust or pores will prevent the uniform application of the adhesive and leave bubbles. Using an excessively small amount of adhesive will bring in air when the adhesive shrinks. Direct blowing will cause the edges of the bonding surface to turn white due to the volatilization of the adhesive. Indoor humidity, temperature, etc. all have a direct effect on the adhesion of plexiglass panels.
