With the development and production, glass also has the distinction between ordinary glass and plexiglass, which has caused some troubles for consumers. Now there are many glass products on the market, and plexiglass is the most recent.

Some years of popular decorative materials, some people think that plexiglass and ordinary glass are no different, this view is actually not correct. What is the difference between plexiglass and ordinary glass? Let's take a look at it together.

First, plexiglass

The raw material of the plexiglass door is plexiglass, and the plexiglass is a polymer transparent material. Its chemical name is polymethyl methacrylate, generally referred to as PMMA, which is formed by polymerization of methyl methacrylate. Has many features that ordinary glass does not have, such as:

1.Aesthetics: The appearance of the plexiglass door is mirror-like, no seams, no wrinkles, exquisite craftsmanship, rich colors and beautiful appearance.

2.light transmission: plexiglass light transmission is very good, after testing its light transmittance to get 96%, and the light projected will be softer.

3.Impact resistance: The impact resistance of plexiglass is more than 200 times that of ordinary glass. It is not a particularly strong external force, and there is basically no problem of fracture and fracture, and the safety is high.

4.long life: plexiglass can ensure that it will not fade after a long time of use, and the quality of the plate has a long service life of 6-13 years.

5.Flame resistance: As a decoration product for building decoration, fire resistance is a must, and plexiglass has good flame resistance, no spontaneous combustion, and even self-extinguishing.

Second, ordinary glass:

Ordinary glass is more exposed, it is a relatively transparent solid material, the main component is silica, is a silicate non-metallic material. Flat glass has

Light transmission, sound insulation, heat insulation, wear resistance, heat preservation, heat absorption, radiation protection, etc., are often widely used in building doors, windows, walls and interior decoration. But as quality gets more and more

Well, the emergence of more and more safe plexiglass, ordinary glass doors are less and less, but there are still many people who choose ordinary glass materials for windows.

The difference between plexiglass and ordinary glass:

1.High transparency: Plexiglass is the most excellent polymer transparent material at present, with a light transmittance of 92%, which is higher than that of glass. The difference between plexiglass and ordinary glass, the lamp of the solar lamp called artificial sun is made of quartz, because quartz can completely transmit ultraviolet rays. Ordinary glass can only pass 0.6% of ultraviolet light, but plexiglass can pass 73%.

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

3.High mechanical strength: The relative molecular mass of plexiglass is about 2 million. It is a long-chain polymer compound, and the molecular chain is very soft. Therefore, the strength of plexiglass is compared.

High, tensile and impact resistant 7 to 18 times higher than ordinary glass. The difference between plexiglass and ordinary glass, there is a heated and stretched plexiglass, the molecular chain

The segments are arranged in a very orderly manner, resulting in a significant increase in the toughness of the material. Nail is nailed into the plexiglass, and even if the nail penetrates, no crack occurs on the plexiglass. Plexiglass and Pu

The difference between the glass and the plexiglass is not broken into pieces after being broken by the bullet. Therefore, the stretched plexiglass can be used as a bulletproof glass and also as a canopy on a military aircraft.

4.Easy to process: plexiglass can not only use the lathe for cutting, drilling machine for drilling, and can be bonded to various shapes of equipment with acetone, chloroform, etc., can also be blow molding, injection, extrusion and other plastic molding methods It is processed into a wide range of products, from aircraft cockpit covers to dentures and trays.

5.The difference in performance: ordinary glass thickness of more than 15 cm, it will turn into a green piece, and can not see things through the glass. The plexiglass can be clearly seen across the 1 meter thick. Because it has a very good light transmission performance, and UV can also penetrate, it is commonly used to manufacture optical instruments. Plexiglass has an amazing performance. A curved plexiglass rod, as long as the curvature is less than 48 degrees, the light can travel along it, like water passing through a water pipe. Light can be detoured, how interesting! With this stunt, it becomes a treasure for the manufacture of surgical light-transmitting glass instruments.
