The use of plexiglass in various fields
Plexiglass has the above excellent properties, making it extremely versatile. In addition to being used as a cockpit cover, windshield and chord window on an aircraft, it is also used as a windshield and window of a jeep, a skylight of a large building (which can prevent shattering), a screen for TV and radar, a protective cover for instruments and equipment, and a casing for telecommunication instruments , Telescopes and optical lenses on cameras.
Professional high-quality plexiglass processing manufacturers use plexiglass to produce a dazzling array of daily necessities, such as buttons made of pearl plexiglass, various toys, lamps and lanterns because of the decorative effect of colored plexiglass, which looks exceptionally beautiful.
Plexiglass has another wonderful use in medicine, which is to make artificial cornea. If the transparent cornea of the human eye is covered with opaque material, light cannot enter the eye. This is blindness caused by total corneal leukoplakia, and this disease cannot be treated with drugs.
Therefore, medical scientists envisioned replacing the cornea with white spots with an artificial cornea. The so-called artificial cornea is to use a transparent material to make a lens column with a diameter of only a few millimeters, and then drill a small hole in the cornea of the human eye to fix the lens column on the cornea, and the light enters the eye through the lens column. The human eye can see the light again.
As early as 1771, ophthalmologists used plexiglass to make a lens column and implant the cornea, but they did not succeed. Later, it took only half a year to replace the plexiglass with crystal and it failed. In the Second World War, when some plane crashes, the cockpit cover made of plexiglass on the plane was blown up, and the pilot’s eyes were embedded with shards of plexiglass. After many years, although these fragments were not removed, they did not further cause inflammation or other adverse reactions in the human eye. This incident shows that plexiglass has good compatibility with human tissues. At the same time, it also inspired ophthalmologists to use plexiglass to make artificial cornea. It has good light permeability, stable chemical properties, non-toxic to the human body, easy to process into the required shape, and long-term compatibility with the human eye. Now, artificial cornea made of plexiglass has been widely used in clinical practice.
