Infiltration device for glass fiber drawing

Abstract

The invention discloses an infiltration device for glass fiber drawing. The infiltration device comprises a workbench, wherein an infiltration box is arranged on the workbench; an infiltration channel for glass fibers to pass through is arranged in the infiltration box; a glue storage tank is arranged at the bottom of the infiltration channel; a first electric heater is arranged on the side wall of the glue storage tank; a glue spraying pool is arranged on the portion, located above the infiltration channel, of the infiltration box; a glue spraying through hole is formed in the bottom of the glue spraying pool; another first electric heater is arranged in the glue spraying pool; a first wire arranging roller and a second wire arranging roller are arranged on the portions, located on the two sides of the infiltration channel, of the workbench correspondingly; a glue scraping mechanism is arranged at the position, located at the filament outlet end of the infiltration channel, of the infiltration box; a glue solution circulating mechanism is arranged between the glue spraying pool and the glue storage pool; and a traction mechanism for pulling the glass fibers is arranged in the infiltration box. The device has the characteristic of good infiltrating and coating effects, effectively avoids the phenomenon of non-uniform glue scraping, and improves the infiltrating effect of the glass fibers.

Description

technical field [0001] The invention relates to the technical field of glass fiber manufacturing, in particular to a soaking device for glass fiber drawing. 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. ...

AI Technical Summary

Problems solved by technology

Among them, the sizing agent is an indispensable surface treatment material in the production of glass fiber. The quality of glass fiber and the variety of varieties largely depend on the sizing agent. If there is no good sizing agent as a guarantee, it cannot be produced. Produce high-quality, multi-variety glass fibers

However, in the production process of this production technology, when the glass fiber passes through the infiltration equipment process, it is difficult to be fully infiltrated by the molten resin sizing agent inside, and the squeegee effect is poor, so that the thickness of the coating layer varies greatly and is easy to form lumps matter, which leads to the appearance of the product with serious floating fibers and reduces the performance of the glass fiber
