Description

Technical Field

[0001] The invention relates to the technical field of glass fiber production, in particular to a method for producing glass fiber. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance and a wide variety of types. Its advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but its disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. In the glass fiber production process, cold water is often used to cool the molten fibers, and a separate cooling water recovery equipment is required, and the cooling speed is slow.

[0003] A Chinese patent discloses a glass fiber production and processing technology (Announcement No. CN110282870A). The patented technology is equipped with a molding module at the outlet of the material discharge module. The molten glass fiber can be quickly cooled and molded by cold air, so that the material can be discharged and cooled and molded at the same time, which effectively improves the processing speed. The cold air is used as a cold source, which can make the cooling process cleaner and solve the problem that water cooling still needs to be treated. The filter net is provided inside the inlet end of the cooling duct to inhale and filter the air and quickly cool it, so as to serve as a cooling source for cooling and molding the material, making the cooling process cleaner. However, it has certain disadvantages: using the same filter to filter the air for a long time, and using the same filter for a long time without switching, will gradually clog the pores on the filter, increase the risk of equipment blockage and failure, and affect the cooling effect of the glass fiber; and the replacement of the filter is more troublesome, requiring a long period of downtime and waiting, which is time-consuming and laborious.
