Acrylic sheet bonding techniques are also very important. The following are some common bonding techniques to analyze their practical skills.
First, docking
Place two acrylic sheets to be docked horizontally on the operating platform, close them, and stick a tape on the bottom to leave a gap of no more than 0.3mm to prepare the adhesive. Use a syringe to inject the Kelly adhesive from the side evenly and slowly from the gap until it is fully filled. After the film is fully cured, remove the tape.
Second, the facade bonding
Facade bonding is one of the most widely used bonding techniques and is commonly used in the manufacture of various acrylic products. First wipe the surface to be bonded clean. It is better to use the master to achieve the bonding so that the adhesive does not shake, which is beneficial to improve the quality of the bonding. The bonding of the acrylic sheet within a thickness of 3 mm can be achieved by directly injecting the Kelly Bond directly and slowly from the side with a syringe. Acrylic sheet bonding with a thickness of more than 3mm can be padded into a thin metal wire, and the bonding can be completed by capillary action. The wire can be drawn before the adhesive is cured, or the tape can be protected by sticking to the part that does not need to be adhered, leaving Apply adhesive to the adhesive part, and then insert it into the acrylic plate to squeeze out the bubbles.
Third, the bevel bonding
The bonding bevel must be at a 90 degree angle to prevent displacement of the surface to be bonded. It should be uniform and slow when applying Kerrybond. The master can be removed after it has been fully cured.
