The acrylic display stand has high mechanical strength. The relative molecular mass of acrylic plexiglass in the acrylic plexiglass display stand is about 2 million. It is a long-chain polymer compound, and the chain forming the molecule is very soft. Therefore, the strength of acrylic plexiglass is relatively high, tensile and resistant The impact ability is 7-18 times higher than ordinary glass. There is a kind of acrylic plexiglass that has been heated and stretched, in which the molecular chains are arranged in a very orderly manner, which significantly improves the toughness of the material. Use nails to drive into this acrylic plexiglass, even if the nail penetrates, there will be no cracks on the acrylic plexiglass. This kind of acrylic plexiglass will not be broken into pieces after being penetrated by bullets. Therefore, the stretched acrylic plexiglass can be used as bulletproof glass, and also as a cockpit cover on military aircraft.
The high transparency of the acrylic display stand. Acrylic plexiglass is currently the most excellent polymer transparent material, with a light transmittance of 92%, which is higher than that of glass. The tube of the sun lamp called the artificial little sun is made of quartz, because quartz can completely transmit ultraviolet rays. Ordinary glass can only transmit 0.6% of ultraviolet rays, but acrylic plexiglass can transmit 73%.
