No. Glass is a product of silica and other chemicals fused together in hail oranges, and its production raw materials are mainly composed of soda ash, limestone, quartz and other chemicals. Its cost is low, easy to form, the source is suitable for the large-scale production of Dawu pants, can produce glass bottles and jars, flat glass, utensils, bulbs, etc.

Plexiglass belongs to plastics, and it belongs to organic synthetic materials.

Organic synthetic materials play a vital role in daily life, agriculture and industrial production.

Be.

Plexiglass belongs to plastics and is an organic synthetic material. Organic synthetic materials mainly refer to the synthesis of small molecule organic compounds, such as olefins, into macromolecular polymers through chemical synthesis. There are many varieties of organic synthetic materials, synthetic plastics, synthetic fibers, and synthetic rubber are the three major synthetic materials we usually refer to.

Plexiglass performance advantages:

1. Plexiglass has high transparency.

Plexiglass is crystal clear, not inferior to ordinary glass at all, and has a high degree of transparency, some people have done experiments, as long as the thickness of ordinary glass exceeds 15 cm, it will be a piece of emerald green in front of you, you can no longer see things clearly through such glass, and even if the plexiglass has the thickness of 1 meter wide stove, you can still see the opposite thing clearly through it.

2. Plexiglass has good light transmittance.

Plexiglass can emit a crystal luster in the sun, with excellent light transmittance, the light transmittance of a transparent plexiglass can reach 93%, much higher than ordinary glass, and the ultraviolet transmittance is as high as 73%, which is more than 100 times that of ordinary glass, in addition to good light transmittance, its light diffusion and light conductivity are also excellent, so it is often used to make lighting equipment and advertising boards.

1.A basic introduction to plexiglass.

Plexiglass, also known as acrylic, is a common plastic material. It is colorless and transparent, with high hardness, strong impact resistance, and good weather resistance, and is often used in automobiles, construction, home and other fields. It is mainly made of polymethyl methacrylate (PMMA), which is a synthetic material.

2.Synthesis of plexiglass.

Plexiglass is synthesized by chemical reactions. The main raw material is methyl methacrylate (MMA), which is polymerized by adding initiators and stabilizers to obtain polymethyl methacrylate. Then, the polymethyl methacrylate is formed into a green body by mechanical or thermal processing, and then post-treatment processes such as heat treatment, stretching, and cutting are carried out to finally obtain plexiglass.

3.Classification of plexiglass.

Plexiglass can be divided into many types according to different production processes and uses, such as ordinary plexiglass, ultra-weather-resistant plexiglass, embossed plexiglass, bulletproof plexiglass, etc. Each type of plexiglass has its own unique properties and uses.

4.Applications of plexiglass.

Plexiglass has a wide range of applications. In the field of construction, plexiglass can be used to make cubicles, ceilings, walls, stairs, etc., and can also be used as an option for building exterior materials such as sunrooms, swimming pools, billboards, etc. In the automotive industry, plexiglass can be used as a material for lamp covers, windows, mirrors, etc.

In addition, plexiglass can also be used to make various trophies, decorations, display cabinets and other daily necessities.

5.Conclusion.

Based on the production process and composition of plexiglass, it can be concluded that plexiglass belongs to the category of synthetic materials. Although its composition contains organic matter, the polymethyl methacrylate obtained by chemical synthesis can no longer be classified as natural organic matter, so the chemical properties of plexiglass are different from natural organic matter. Therefore, plexiglass can be considered as an organic synthetic material.

6.Advantages of plexiglass compared to other materials.

The advantages of plexiglass are its transparency, durability, UV protection, impact resistance, etc. Compared to glass, plexiglass is more resistant to falls. Compared to other polymeric materials, plexiglass has better transparency and a longer service life.

7.The environmental friendliness of plexiglass.

Plexiglass is a green and environmentally friendly material. In the production process, the concept of circular economy can be adopted for ** reuse, so as to reduce waste. In addition, plexiglass can achieve low-carbon environmental protection, long service life, anti-aging, anti-corrosion and other advantages, which also makes it one of the most widely used polymeric materials.

8.The development prospects of plexiglass.

With the continuous development of science and technology, the application field of plexiglass will continue to expand. In the field of high-tech industry and environmental protection, plexiglass will be more widely used, and its production process will be continuously improved, so as to improve its product quality and performance.

It is a kind of polymer compound, and its chemical name is polymethyl methacrylate. Plexiglass has good transparency, chemical stability, weather resistance, and it is also easy to stain. More than that, the machine glass can be used in machinery, construction, and medical industries, and it can be used for common windows and fruit bowls in our lives.
