Abstract

The invention discloses low-boron glass for glass fiber, glass fiber and a manufacturing method of the glass fiber. A glass composite comprises the following components by weight percent: 57-65 percent of SiO2, 5-9 percent of Al2O3, 4-10 percent of Na2O, 1-5 percent of K2O, 3-5 percent of CaO, 0.2-2 percent of MgO, 6.4-15 percent of BaO, 3-5 percent of ZnO, 0-0.1 percent of Fe2O3, 0-1 percent of B2O3 and 0.1-0.4 percent of F. Low-boron glass does not contain boron oxide or contains low-concentration boron oxide and relatively high-concentration barium, and the glass fiber can meet the requirement of no boron or low boron in some special industrials. A high-efficiency filter manufactured by using the glass fiber is very suitable for a cleaning environment and can avoid the problem of boron pollution. The glass fiber has higher humidity resisting ratio, and can resist degradation in an environment with high humidity, therefore, the glass composite of the invention with the concentration can be used for manufacturing thin glass fiber through a flame method and a centrifugal process in the prior art.

Description

technical field [0001] The invention relates to a glass fiber raw material and a glass fiber manufacturing process, in particular to a low boron glass used for glass fiber, glass fiber and a glass fiber manufacturing method. Background technique [0002] Ultra-fine glass fiber made of molten glass has the characteristics of insulation, heat resistance, corrosion resistance and high mechanical strength; it is widely used in construction, transportation, electronics, electrical, chemical industry, metallurgy, environmental protection, national defense, etc. In the industry, glass fiber is a very good substitute for metal materials. With the rapid development of the market economy, the application of glass fiber will become more and more extensive. [0003] Glass fiber is the main raw material for making air filter paper, and the glass fiber used to make high-efficiency and ultra-high-efficiency air filter paper generally contains a large amount of boron, such as boron oxide wi...
