Acrylic sheet

Acrylic, also known as PMMA or plexiglass, is derived from English acrylic (acrylic plastic), and its chemical name is polymethyl methacrylate.
It is an important plastic polymer material that was developed earlier. It has good transparency, chemical stability, weather resistance, easy dyeing, easy processing, and beautiful appearance. It has a wide range of applications in the construction industry. Plexiglass products can usually be divided into cast plates, extruded plates and molding compounds.
 

Characteristic

1. With crystal-like transparency, the light transmittance is above 92%, the light is soft, and the vision is clear. Acrylic colored with dyes has a good color development effect.

2. It has excellent weather resistance, high surface hardness and surface gloss, and good high temperature performance.

3. It has good processing performance, which can be used for thermoforming or mechanical processing.

4. It has a light transmittance comparable to glass, but the density is only half that of glass. In addition, it is not as fragile as glass, and even if it is broken, it will not form sharp fragments like glass.

5. The wear resistance is close to that of aluminum, with good stability and corrosion resistance to various chemicals.

6. It has good printability and sprayability. The use of appropriate printing and spraying techniques can give acrylic products an ideal surface decoration effect.

7. Flammability: It is not spontaneously combustible but is flammable and does not have self-extinguishing property.

Bonding method

1. Butt joint: Place two plexiglass plates that need to be jointed horizontally on the operating platform, close together, 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. 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 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 and other profiling to prevent the displacement of the bonded surface. The adhesive should be applied evenly and slowly. The master can be removed only after it is completely cured.

4. Plane 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 adhesive, and then put it down evenly and slowly, and drive out the bubbles from one side to complete the bonding. The plexiglass adhesive can erode 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 air blowing will make the edges of the bonding surface white due to the volatilization of the adhesive.
Indoor humidity, temperature, etc. all have a direct impact on the adhesion of plexiglass panels.
