Plexiglass and ordinary glass look like a family. In fact, they are completely different. The "father" of ordinary glass is silicate, but the "parents" of PMMA are acetone, methanol, sulfuric acid and hydrogen cyanide.
The real name of plexiglass is polymethyl methacrylate. This name is quite awkward, because it is a synthetic polymer, so it is generally called plexiglass.
The character of plexiglass is generally more stubborn than ordinary glass. Although it is half as dense as ordinary glass, it is not as fragile as glass. It is very transparent, glittering and translucent, and has a good thermoplasticity. It can be heated to make it a glass rod, a glass tube or a glass board at any time, because it has a lovely appearance and character, so it has a wide use.
When jet aircraft fly at high speed in the cloud, they often encounter severe vibration, sudden change of temperature and pressure of air flow, which is a severe test for the window glass of the aircraft cockpit. Who can stand this test? Organo glass. If it is a fighter, when the enemy is pursued, the plexiglass is hit by a bullet, and it will not break apart, but only a small hole will not happen again.
Ordinary glass thickness of more than 15 centimeters, it will become green, and can not see through the glass. The plexiglass is 1 meters thick, and can clearly see the opposite things. Because its transmittance is quite good, and ultraviolet radiation can penetrate, so it is commonly used to manufacture optical instruments.
Organic glass products also have an amazing performance, a curved organic glass rod, which, as long as the bend is less than 48 degrees, can be projected along it, like water through the water pipe. The light can take a detour, and how interesting it is! With this stunt, it becomes a treasure for making surgical transmitting glass instruments. Therefore, when doctors operate in the operation room, they need not worry about not seeing clearly.
Plexiglass is light, tough, chemically stable, heated and plastic, so it has a wide range of uses.
