The difference between ordinary glass and plexiglass

The difference between ordinary glass and plexiglass

What plexiglass that? Plexiglass is an important development earlier thermoplastic, it has excellent light transmission properties, so that we are now the latest glass, then what is the difference between ordinary glass and plexiglass is it? 


1, a high degree of transparency: plexiglass is the best polymer transparent material, light transmission rate of 92%, high transmittance than glass. Plexiglass and the difference between ordinary glass, known as the small artificial sun sun lights the lamp is made of quartz, because quartz completely through the UV. Only through ordinary glass, 0.6% of ultraviolet rays, but was able through the plexiglass 73%. 

2, light weight: plexiglass density 1.18kg / dm3, the same size of the material, and only half the weight of ordinary glass, aluminum (of the light metal) of 43%. 

3, high mechanical strength: relative molecular mass of plexiglass approximately 2 million, it is a long-chain polymers, and the formation of molecular chains is very soft, so the strength of the plexiglass is relatively high, tensile and impact the ability of 7 to 18 times higher than ordinary glass. Plexiglass difference between ordinary glass, there is a heated and stretched-treated glass, in which the molecular chains arranged very orderly, and the toughness has improved significantly. With a nail into this plexiglass, even if the nail penetration, and no cracks on the plexiglass. The difference between ordinary glass, plexiglass, plexiglass after the breakdown of this same bullet will not break into pieces. Therefore, stretching processing plexiglass can be used as bullet-proof glass, also used as a military aircraft cockpit cover. 

4, ease of processing: plexiglass can be used not only for cutting lathe, drill press to drill, and can use acetone, chloroform and other appliances bonded into various shapes, can also blow molding, injection, extrusion and other methods of plastic molding processing to National Cheng Kung University cockpit cover, small and other kinds of dentures and denture products. 

5, the difference in performance: the thickness of ordinary glass is more than 15 cm will become green one, and could not see anything through the glass. Via one meter thick plexiglass can also clearly see the opposite things. Because of its light transmission performance is quite good, plus ultraviolet light can penetrate, so used to manufacture optical instruments. 

Plexiglass There is another amazing performance: a curved plexiglass rods, as long as the curvature of less than 48 degrees, the light can be projected like water through the pipes as it came along. Ray can detours, how interesting! With this stunt it becomes a light transmitting glass manufacturing surgical instruments treasures.
