Use of glass fibers
Glass is a kind of brittle material known . Interestingly, the glass once heated , drawn into a much finer than a human hair fiber glass After that, it seemed to have completely forgotten his own nature and become like synthetic so soft and tough even more than the same thickness of the stainless steel wire !
Then , the glass fiber dim place it
Glass with glass fiber twisted rope, can be said to be " the king of justice ." Thick as a finger glass rope , actually be able to lift a truck loaded with goods ! Seawater corrosion of the glass rope afraid , not born rust , so as mooring ropes , cranes, slings and very appropriate . rope made of synthetic fibers , although prison, but it will melt at high temperatures , while the glass rope was not afraid , therefore , the use of glass Shengte another ambulance safety .
Glass fiber is organized , able to weave all kinds of glass fabric - glass cloth , glass cloth both afraid of acid, alkali not afraid , so the cloth used as a chemical factory , very good. Recent years, many factories have made of glass instead of cotton cloth , sack cloth, making bags. such bags not mold and rot , moisture and corrosion , durable, very popular with people welcome, and also save a lot of cotton and linen . has exquisite pattern large sheets of glass Qiangbu with an adhesive to the wall a nice, eliminating the need for paint and maintenance , as long as the dirty cloth across it, they immediately became clean the walls .
Both fiberglass insulation, and heat-resistant , so it is very good insulation. Currently, the majority of our motors and electrical plants have made extensive use of glass fiber insulation . One hundred 6,000 kilowatt turbine , which used glass fiber insulating parts do actually reached more than eighteen hundred pieces ! thanks to fiberglass insulation, both to improve the motor performance , but also reduces the size of the motor , the motor also reduces the cost really threefold .
Another important use of fiberglass and plastic is to manufacture all kinds of glass fiber composites . Example, the layers of glass cloth soaked in hot melt the plastic , compression molding since become famous " glass ." fiberglass even tougher than steel , not only will not rust, and corrosion , and weighs only a quarter of the same volume of steel , so use it to manufacture boats , cars, trains shell and machine parts, not only can save a lot iron and steel , and also due to lighten the car, the weight of the boat itself , so that the effective load greatly improved due to not rust, can save a lot of maintenance costs.
If the glass melting, with high-speed airflow or flame blown it thin and short fibers , which became the glass wool . Had a moisture superfine wool , more than 200 together only a hair so thick . glass wool insulation with a strong nature , 3 cm thick glass wool , and its ability to compete insulation equivalent to 1 meter thick brick wall ! glass wool sound-absorbing effect is also very good , so it is used in many industrial sectors insulation, noise, heat , vibration and filtering materials .
Fiberscope emerged in recent years , allowing physicians to directly observe stomach, duodenum , heart, and other organs situation which is also the glass fiber contribution of light from one end of the glass fiber into a curved glass fiber , when the light forward to reach the inner surface of the glass fiber , it is totally reflected to the diagonally opposite the inner surface , and so forth reflect the light like walking zigzag bridge -like twists and turns , and finally from one end to the other end of the course, the actual use is to tens of thousands of glass fibers bundled together to form a glass fiber rods in order to prevent the light in fiber rods between "leak" , but also fiber rods wrapped in a layer outside the low refractive index of the material , as long as both ends of the glass fibers densely arranged in the same order , the optical image without distortion can be from one end to another end . lighting using an external power supply , fiber rods installed in the front lens , the latest "full visual style " fiber microscope , the observation window can move look , you can also become a side angle of rotation can also be fitted with miniature cameras or color TV for teaching or multiplayer consultation purposes.
In addition , the use of an optical fiber made of glass fibers for telephone communication , are also completely successful. Its capacity , transmission loss is minimal, from electromagnetic interference , which can save metallic copper , but also the transmission of images for TV telephone .
Indeed, many uses of glass fibers , with the rapid development of modern science and technology , glass fiber will make more contributions .
