Abstract

The invention relates to a production process for glass fiber yarn. The production process comprises the steps: selecting the following raw material ingredients in percentage by weight: 1% to 30% of waste / used beaded glass, 1% to 40% of cullet, 1% to 30% of quartz sand, 22% to 35% of pyrophyllite, 3% to 15% of feldspar, 5% to 13% of borax, 1% to 4% of calcite, 3% to 7% of dolomite, 0.5% to 2% of fluorite, 2% to 5% of mirabilite and 0.2% to 0.5% of composite clarifier; and carrying out processes such as material preparing, melting, drawing, baking and yarn making, thereby producing the high-quality glass fiber yarn. According to the production process for the glass fiber yarn, disclosed by the invention, the waste / used beaded glass and the cullet serve as main raw materials, so that waste resources can be effectively utilized, and the pollution to environments is reduced; and the produced glass fiber yarn is stable in product quality, and the strength of the produced glass fiber yarn can meet requirements.

Description

technical field [0001] The invention relates to a glass fiber, in particular to a production process of a glass fiber yarn. Background technique [0002] Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than 20 microns, which is equivalent to a hair. 1 / 20-1 / 5 of that, each bundle of fiber precursors consists 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 other national economy fields. [0003] Its main components are ...
