Buying materials is most afraid of buying plates without quality assurance. After all. a plate is not cheap. Take the acrylic plate as an example. The board can vary from a few hundred to a thousand. How to buy a safe board. the following suggestions are for reference:
1. transparency identification
When a good acrylic sheet is exposed to white light. the light that is transmitted is very pure. without yellowing or bluing. and the light transmittance of the good sheet is greater. The pure new material acrylic board has a pure color appearance and the recycled board has a yellowish appearance.
2. thickness identification
One of the important characteristics of acrylic sheets is thickness. Generally speaking. how thick is enough thickness. the thickness must be asked when purchasing. This is a key factor. The pure new material acrylic board has excellent surface hardness and scratch resistance. and does not stimulate the smell when cutting; the surface of the recycled board is easily scratched. and the odor is irritated when cut.
3. fire identification
Good acrylic is not suitable for burning and does not produce an unpleasant odor during processing. Many materials on the market are posing. and this can be tried with the scrap they say. When the pure new material acrylic plate is heated by thermoforming. bubbles and deformation are not easily generated; when the regenerative plate is heated by thermoforming. it is easy to have bubble deformation.
4. roasted soft identification
Good acrylic blistering plates can be separated even if they are attached together. and the poor materials are very difficult to separate when they are baked together. The pure new acrylic sheet has long-lasting adaptability to paint and ink; the recycled board is sensitive to paint and ink. and is prone to silver streaks or cracks.
5. soft edge identification
The new plates and good materials are factory-packed with soft edges. for the purpose of preventing rubbing. So this can be used as a different method of recycling materials and new sheets.
6. quality identification
Plate manufacturers usually provide samples and actual products. which can be checked according to the color and some parameters.
