High-quality Acrylic Sheet features are as follows:
1. Optical recognition After opening the lighting function with mobile phone lighting, the lights are relatively pure, and the mouth of the acrylic sheets are not yellow or blue. 2. The color of the Pmma Sheet mouth The mouth (edge of the plate) of the excellent and transparent acrylic board should be transparent. If the yellow and colorful hair become hazy or white, it must be a sub -product. If the color of the board is yellow, it should be produced by retracting the garbage regeneration material. 3. Soft glue edge discernation In order to prevent collision, the new board and good materials are packed with soft glue edges. Therefore, this can be used as the difference between recovering materials and new boards, but the pouring board itself will have PVC gum edge. Pay attention to the PVC and acrylic interface. If it is obviously too yellow, it is too yellow. Or obvious whitening is also a regenerative crack. 4. Facial feel By touching the acrylic board, if the acrylic board is smooth, rounded, delicate, and feels good, it is not easy to leave the traces of fingers. 5. Appearance testing The appearance of a good Acrylic Plate is more beautiful, good light transmittance, there will be no numbness, less crystal points, and no bad phenomenon such as yellow and contraction. On the contrary, bad materials are so -called retracting material production boards. The appearance is poor. There are many anesthesia, there are more crystals, there are more impurities, and the quality is difficult to guarantee. 6. Listening If the sound of the tap pmma board is unclear and dull, it is true. On the contrary, if the tap statement is clear, the PS board should not be an acrylic board. It is also necessary to pay attention to the market for many domestic acrylics, and the price is relatively cheap. It is most likely that the PS board is pretending to be an acrylic board. 7. Burning with fire If there is a blue flame when burning, it is confirmed that it is acrylic. If the black smoke is dripped, it is a PS board or a secondary product. After the burning is finished, press it with a hard object and leave. The drawing is the best way to pour the board.
