1. The surface hardness of plexiglass (acrylic) is equivalent to that of aluminum, so scratch should be avoided when using or processing. Generally, the surface of plexiglass plate is protected by kraft paper or transparent film, and it should not be torn.
If it is scratched, the original glossy surface can be restored by polishing technology.
2. The thermal deformation temperature of PMMA is about 100 ℃, and the continuous temperature should not be higher than 90 ℃. It is easy to deform under high temperature and cannot be placed in the place with continuous high temperature.
3. Plexiglass (acrylic) is easy to static electricity and absorb dust. Clean with soft cotton cloth dipped in 1% soapy water.
4. The organic glass (acrylic) casting board has a certain expansion coefficient, so it must be considered to leave enough expansion gap when installing the plexiglass (acrylic) board.
