1, the problem of adhesion to dust If the surface of the acrylic mirror is wiped with a dry cloth, there is a tendency to be charged by friction, and it is easy to adhere to the free dust in the air and cause scratches. It is recommended that you use a soft cloth dampened with antistatic agent or methanol containing antistatic agent, gently wipe.

2, the problem of line expansionacrylic mirror, like many plastics, has a linear expansion ratio and must be considered for expansion and contraction due to temperature changes. It is hoped that it can be stored and processed (used) under constant conditions. If there is a temperature difference, for example, at a temperature difference of 2 (the temperature difference of TC, there is about 1.4 mm of expansion and contraction per lm length.

3. Note on temperature: The long-term use temperature of the pmma board is 80 ° C, which will be deformed at high temperatures. Therefore, if you keep the temperature, control it at least 50 °C.

4, Attention to injury, scratching The surface hardness of acrylic resin is almost the same as that of aluminum. Although it is a hard type in plastics, it must be noticed when used. In order to protect the watch, a protective paper is attached to the acrylic resin. In order to prevent scratches and adhesion of dust during use, it is recommended that you use the protective paper as much as possible and then peel off.
