Composition: The most common type of glass fiber in glass fiber is E-glass. E-glass is aluminoborosilicate glass. The content of alkali metal oxide is less than 1% w/w. It is mainly used for glass fiber reinforcement. plastic.
Other types of glass are A glass (soda lime glass with almost no boron oxide or no boron oxide), E-CR glass (chemical/chemical resistance; aluminosilicate silica with alkali metal oxide less than 1% w/w) Salt, high acid resistance), C glass (soda lime glass with high boron oxide content, used for short glass fibers and insulating materials), D glass (borosilicate glass named after low dielectric constant), R glass (Without aluminosilicate glass) MgO and CaO with high mechanical requirements, and S-glass (aluminosilicate glass without CaO but with high MgO content and high tensile strength.
Name and use: Pure silica (silica), when cooled in the form of fused silica into glass without a true melting point, can be used as a glass fiber for glass fiber, but the disadvantage is that it must work at a very high temperature. In order to reduce the necessary working temperature, other materials are introduced as "fluxing agents" (ie, components that lower the melting point).
Ordinary A glass (alkali metal lime is "A") or soda lime glass that is pulverized and ready to be remelted is the so-called cullet, which is the first type of glass used for glass fibers.
E-glass (called "E" because of its original electrical application), does not contain alkali, and is the first glass formulation used for continuous filament formation. Now, it constitutes most of the world's glass fiber products and is the largest single consumer product of boron minerals in the world. It is susceptible to attack by chloride ions, so it is a poor choice for marine applications.
S glass is used when tensile strength (high modulus) is important ("S" stands for "stiffness"), so it is an important building and aircraft epoxy composite material (called R glass in Europe, in "reinforcement" Called "R"). C glass ("C" stands for "chemical resistance") and T glass ("T" stands for "insulation" (North American variant of C glass)) are chemically resistant; both are often blown glass fibers Found in the insulation class.
