Acrylic bonding method
The bonding process of acrylic products plays a crucial role in the processing of acrylic products. Bonding technology plays an important role in dealing with the clear and transparent characteristics of acrylic and reflecting the value of acrylic tobacco and alcohol packaging crafts. The permeability of the bond greatly improves the grade and taste of acrylic crafts. In fact, PG acrylic has in-depth research and rich experience in how to correctly use bonding technology.
It is important to note that the quality and effectiveness of bonding depends not only on the correct process steps, but also on the quality of the adhesives and sealants used. Therefore, we always insist on the use of high quality bonding materials to ensure the best quality and effect of the final product. In addition, we will also carry out special bonding treatment according to the characteristics and needs of different products, in order to maximize the quality and taste of products.
The bonding of acrylic plate is mainly affected by two aspects, one is the applicability of the adhesive itself; The second is the technique of bonding.
There are many acrylic plate adhesives in the domestic and foreign markets, there are two main types, one is two-component, such as universal adhesive, epoxy resin; There is also a single component, such as CHCl3(chloroform). Generally speaking, the two-component adhesive is bonded by curing reaction, and the single-component adhesive is the final volatilization of a solvent to achieve bonding.
The advantage of the two-component acrylic adhesive is its excellent bonding effect, no bubbles after bonding, no white, and high strength. However, its operation process is more complex, more difficult, the curing time is long, the speed is slow, so it is difficult to adapt to the needs of large-scale production.
In contrast, the general single-component acrylic adhesive has the advantage of rapid curing and meeting the production process requirements of mass products. However, the products after bonding are easy to produce bubbles, white, and poor weather resistance, which directly affects the external beauty and product quality of acrylic products.
Therefore, in the processing of acrylic products, how to choose the right adhesive to improve the grade and grade of acrylic products has become a key issue to be solved in the bonding process.
Docking acrylic is actually a technical job, you know? Sometimes two boards need to be joined together, and this is the time to pay attention to the method. First, place the two acrylic plates to be joined horizontally on the operating platform, close them, and stick a tape on the bottom. Then, leave a gap, the width is not more than 0.3mm, used to apply the adhesive. Then, using a syringe, carefully pour the adhesive evenly and slowly from one side through the slit. Don't fill it too fast or too fast. Make sure it's full. Once fully cured, you can remove the tape and complete the docking. This process seems simple, but every step should not be sloppy!
Facade bonding is a very common bonding technique. We often use it in the production of various acrylic electronic digital display stands. First, we need to clean the surface that needs to be glued. If you want to make the bond stronger, you can refer to some methods, such as using a mold, so that the bond will not shake, to help improve the bond quality.
For the bonding of an acrylic plate with a thickness of 3mm, you can try to insert a thin metal wire and use the capillary action to complete the bonding. Pull out the wire before the adhesive cures, or you can glue the tape first and then apply the adhesive. These are some common methods that can help you complete the bonding of acrylic sheets.
The third is inclined plane bonding: the inclined plane must be bonded at a 90 degree Angle to prevent the surface from shifting. The acrylic adhesive should be applied evenly and slowly. Do not remove the mold until it is fully cured. The fourth is surface bonding: plane bonding is a more special bonding method. First of all, the adhesive surface is wiped clean and placed horizontally, and an appropriate amount of adhesive is poured on it. Place one side of the other acrylic plate diagonally onto the acrylic plate that is coated with the adhesive, and then lower it evenly and slowly, driving out the air bubbles from one side to complete the bonding. Acrylic adhesive can erode the surface of the acrylic plate and leave traces that are difficult to eliminate, so you can use a self-adhesive tape to protect the parts that do not need to be glued.
