The processing of plexiglass is very simple to scratch, which results in our impression that acrylic products will be scratched. In fact, not all acrylic products are simply scratched. The surface hardness of acrylic materials is differentiated by grades, and only organic materials with low hardness grades Glass processing is simple to distinguish the hardness grades of plexiglass processing and inspection methods: Since we talked about the hardness of plexiglass processing, the following Pinfeng acrylic processing factory will tell us: how to distinguish the surface hardness of acrylic. The hardness of plexiglass processing is generally divided into from low to high: 2B, 1B, HB, 1H, 2H, 3H, and the hardness that can reach 3H surface hardness is considered to be quite high.
If you want to know the hardness of plexiglass processing, the most professional way is to use a hardness tester to check, so the measured data is highly accurate; if there is no such equipment, it does not matter, the pencil is not The numbers 2B, 1B, HB, 1H, 2H, 3H are also printed. The easiest way is to scratch the acrylic surface of the corresponding type of pencil in turn. The one that can leave scratches on the plexiglass processing corresponds to the pencil. That hardness.
