Production system and production method of high-strength glass fibers

Abstract

The invention discloses a production system and a production method of high-strength glass fibers, and belongs to the technical field of inorganic non-metallic materials. The production system comprises a mixing device, a heating device, a tank furnace wire drawing device, an infiltration wire collecting device and a glass fiber forming device, wherein glass fiber raw materials are uniformly mixed through the mixing device and are pneumatically conveyed to the tank furnace wire drawing device, the tank furnace wire drawing device is heated through the heating device to melt the raw materials, then wire drawing forming is performed to obtain glass fiber precursors, the surfaces of the glass fiber precursors are coated with an impregnating compound, and the precursors are collected to obtain a precursor cake. All the raw materials in the glass fiber act together, so that the prepared glass fiber not only has better tensile strength, but also has higher elastic modulus.

Description

technical field [0001] The invention relates to the technical field of inorganic non-metallic materials, in particular to a production system and production method of high-strength glass fibers. Background technique [0002] Fiberglass is an inorganic non-metallic material with excellent performance. It has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but it is brittle and poor in wear resistance. It is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, and weaving. The diameter of the single filament is several 1 micron to more than 20 microns, which is equivalent to 1 / 20-1 / 5 of a hair, and each bundle of fiber filaments is composed of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and...

AI Technical Summary

Problems solved by technology

[0003] The high-strength glass fiber composition in the prior art has a relatively high molding temperature, and the components and their proportions added to the formula are unreasonable, which will easily lead to performance degradation or pollution

For example, the addition of antimony oxide as a clarifying agent will affect human health; Fe 2 o 3 The introduction of components can easily lead to phase separation of the glass, resulting in poor stability and mechanical strength; too high a magnesium oxide content will increase the crystallization tendency of the glass

In addition, the raw materials are mixed unevenly in the conventional production process of glass fiber, and the equipment is complicated.
