From glass to the web, how did the development of chemistry drive history? When "chemistry" is mentioned, many people often look embarrassed, thinking that it is a difficult subject in high school. In fact, our daily routine from waking up in the morning to drinking beer after get off work is actually inseparable from chemistry. Although chemistry is a science that studies the structure, properties and reactions of matter, in the book "The History of the World Is Written by Chemistry: From Glass to Mobile Phones, From Fertilizers to Explosives, An Interesting Introduction to Chemistry" let us see how the development of chemistry driving history? The growth and decline of power and the way of life of various countries have also changed with the synthesis of new substances. The author combines history and chemistry, tells you the past and present of various materials and substances in your life with easy-to-understand text and illustrations, and relevant interesting anecdotes, leading readers to re-experience the mystery and fun of chemistry. The following are the highlights of this book: modern with glass From the time we wake up in the morning to the time we go to bed, we are exposed to an astonishing amount of glass. Turn on the switch after getting out of bed, and the glass-covered fluorescent lamp or LED lamp will illuminate the room. The mirror that reflects your face is also glass. In addition, glass dishes and glasses are indispensable on the table. Look at TVs, smartphones, computers, they all have glass covering their screens. Through the glass windows, sunlight shines into the house, refreshing the atmosphere. Go to work! Whether you are in a car, bus or subway, the windows are made of glass. Of course, workplaces and school buildings also use a lot of glass. Living in modern times, you cannot imagine a living space without glass. Glass is characterized by being transparent and easy to form. In 1959, the Pilkington Company of the United Kingdom introduced a revolutionary invention for the flat glass industry, that is, float glass (also known as "annealed glass"). Float glass is to heat the molten glass in the boiler to about 1600 degrees Celsius, and then pour it into the molten tin slurry. After the molten glass floats on the tin surface, it will spread evenly. The surface of liquid metal is completely smooth, and the flat glass that gradually cools and naturally becomes flat can be continuously led out of the tin bath. Sanding is also not required afterwards, resulting in flat glass that is almost perfectly smooth on both sides. In addition, the upsizing of equipment also improves productivity and promotes energy saving. In order to meet the needs of the automotive industry, the glass industry has produced thin and flat float glass with a thickness of 0.2 to 0.3 mm. Later, the thin plate technology was further developed to produce ultra-thin glass with a thickness of only 0.07 cm to 0.11 cm. . The glass industry is divided into three parts: flat glass, optical glass, and glassware (bottles, household appliances, decorations, etc.), and flat glass is the center of gravity. The disadvantage of glass is that it is hard and brittle, heat-resistant but not resistant to severe temperature changes. Therefore, laminated glass whose shards do not scatter, strengthened glass which shatters into fine particles, and heat-resistant glass which can withstand high temperatures were developed.
