Problems solved by technology

[0003] And alkali-free glass fiber, also known as E glass fiber, refers to glass fiber with low content of alkali metal oxides, and the glass fiber produced in the existing production process of alkali-free glass fiber yarn is weak in high temperature resistance and resistant to high temperature. The shear performance and corrosion resistance are poor, and it is difficult to meet the needs of some special places

Description

technical field [0001] The invention relates to the field of glass fiber yarn, in particular to a production process of an alkali-free glass fiber yarn. Background technique [0002] Glass fiber is a kind of inorganic non-metallic material with excellent performance. It has many kinds, good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. The seven kinds of boronite are made of raw materials through high temperature melting, wire drawing, winding, weaving and other processes. It is composed of hundreds or even thousands of monofilaments. Glass fibers are usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy; [0003] E-glass fiber, also known as E-glass fiber, refers to glass fiber with low alkali metal oxide content, while the glass fiber produced in the existing E-glass fiber yarn production proces...
