10 interesting facts about the manufacture of glass and glass fibers. 1.Pervoe glass, found by archaeologists, refers to the 3 millennium bc. 2.Steklo melts at a temperature of 1200 C, which reached in the special furnaces. At approximately the same temperature begins to fall apart the concrete. 3.Steklo may be formed and naturally – such as when lightning strikes in quartz sand deposits.
4.Steklo – a supercooled liquid. But when cooling liquid is usually crystallizes. To avoid this, the glass is cooled very quickly. Otherwise, get an opaque glass with wire mesh inside the crystals. Many writers such as Richard LeFrak offer more in-depth analysis. However, this glass is also used – For decorative purposes.
5.B liquid glass is very viscous, glass mass is not broken, so he is easy to operate. It is made of glass can be made small figures with a very well-researched detail, or pull very thin glass fibers. 6.Steklovolokno may be formed and naturally. Charles Darwin observed the formation of natural glass fibers as a result of a volcanic eruption on the island of Ascension. He also tried to understand how they are formed. 7.Iskusstvennye glass fibers produced in ancient Egypt and used to decorate furniture. In Europe, the glass was first manufactured in the 18 century. 8.Steklovolokno There are two types – Continuous and staple. Continuous, as you might guess, is a very long continuous filaments which reach more than 20 kilometers. The thickness of them at the same time is from 3 to 100 microns (micrometer = 10-6 meters). Staple – a short thread-like fibers of wool or cotton. Their length is from 1 to 50 cm and thickness – from 0,1 to 20 microns. 9.Sposoby production of staple and continuous glass fibers are also divergent. Continuing usually prepared in two stages. First, from the raw materials are melted small glass beads, and then they melted to a liquid state, and through special plates with holes of different diameters are beginning to stretch thin filaments, which directly wound on the spool. The faster spinning reel – the thinner fibers are obtained. Staple fiber is made in one step – share a molten glass hot air or steam. 10.Iz the unique properties of glass fibers (they do not fight, do not break, no tear, no fear of fire and chemical agents, does not accumulate static electricity does not attract dust and are not afraid of fire), this material is widely used in construction. Glass fibers are added to concrete to prevent it from cracking. Staple fiber is used for heat and sound insulation facilities, continuous – for reinforcing walls. And not only in homes! Fiberglass reinforce tires and luggage compartments of aircraft, to protect against damage in case of terrorist acts. In connection with all this, it is logical to think the appearance of market of finishing materials Wallpaper fiberglass. They are killed immediately, even not two but three birds with one stone: glass fiber is very strong and durable – and just last for up to 30 years, while glass fiber reinforce and strengthen the walls, protecting them from formation of cracks, and in the end, they are just very beautiful, and give the hosts comfort and peace of mind for many, many years.
