The application and development of fiberglass（II）

Fiberglass is able to weave all kinds of fiberglass fabric - fiberglass cloth. Fiberglass cloth is not afraid of acid and alkali, fiberglass chopped strand mat so the cloth used in chemical factory is very good. In recent years, many factories have adopted fiberglass cloth instead of cotton, cloth sacks, making bags. Such bags not mold and rot, corrosion proof, durable, very popular with people of welcome, and also save a lot of cotton. Beautifully patterned wall covering large sheet of glass paste, using an adhesive to the wall a nice, eliminating the need for paint and maintenance, dirty cloth as long as a touch, immediately become clean the walls.

Glass fiber is insulation and heat, so it is a very good insulating material. At present, the majority of our motors and electrical plants have extensive use of fiberglass insulation. A 6000 kilowatts of turbine generator, fiberglass insulation parts which do actually reach more than eighteen hundred pieces! Thanks to fiberglass insulation, both to improve the performance of the motor, but also reduces the size of the motor, also it reduces the cost of the motor is really threefold.

Another important application of glass fibers is cooperate with plastics, which manufacture all kinds of glass fiber composites. For example, the layers of glass cloth dipped in hot melt plastic, compression molding since become famous "glass steel." FRP even tougher than steel, neither rust, and corrosion, and weighs only a quarter of the volume of the same steel and therefore use it to make ships, 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, the effective load greatly improved. Because not rust, you can save a lot of maintenance costs.

All kinds of Glass fibers with good insulation, heat resistance, corrosion resistance and high mechanical strength, which is an excellent inorganic non-metallic materials. Glass fiber with a diameter smaller and intensity increased as the reinforcement material reinforced plastic applications, the biggest feature is the tensile strength. Tensile strength under the standard condition is 6.3 ~ 6.9 g / d, a wet state 5.4 ~ 5.8 g / d. Density 2.54. Good heat resistance temperature of 300 ℃ no effect on intensity. Has excellent electrical insulation properties, is a senior electrical insulating material, also used in insulation and fireproofing material shield. Generally concentrated alkali corrosion, hydrofluoric acid and concentrated phosphoric acid.

Glass fiber commonly used as a reinforcing material, electrical insulating materials and insulation materials, circuit boards and other economic fields composite materials. Glass fiber is more high-temperature resistant than the organic fibers, non-combustible, corrosion, heat insulation, sound good, high tensile strength, good electrical insulation. But brittle, poor wear resistance. It usually used as Industrial filter materials, corrosion, moisture, heat insulation, sound insulation, shock-absorbing material. It’s a kind of reinforcing material, it can be used to make reinforced plastic or reinforced rubber, glass fibers as a reinforcing material has the following features, these features make the use of glass fibers is more extensive than other types of fibers.
