Abstract
The invention discloses a production process of glass fibers, and relates to the technical field of production of glass fibers. The production process comprises the following steps: grinding SiO2, Al2O3, B2O3, CaO, MgCO3, ZnO and TiO2 and blending the materials according to certain proportions so as to obtain a batch mixture, melting the batch mixture at high temperature to obtain a molten glass raw material, forming glass balls, eliminating glass balls containing bubbles or impurities and re-melting high-quality glass balls so as to obtain continuous glass fibers. The technical scheme disclosed by the invention is simple in production technology, not high in production condition requirement, high in production efficiency and relatively good in product quality.
Description
Technical field
The present invention relates to glass fibre production technical field, be specifically related to a kind of production technique of glass fibre.
Background technology
Glass fibre is a kind of ceramic of excellent performance, and it is for raw material is through high temperature melting, wire drawing, doff, the technique such as to weave cotton cloth with glass sphere or discarded glass.Finally form various product, the diameter of glass fiber single filament is from several micron to twenties meters microns, be equivalent to the 1/20-1/5 of a hairline, every bundle fiber precursor all by hundreds of even thousands of monofilament form, usually used as the strongthener in multiple material, electrically insulating material and heat-insulating material, circuit substrate etc., be widely used in national economy every field, but the production technique of existing glass fibre is comparatively complicated, working condition requires that the high production efficiency that causes is low, and quality product is not high.
Summary of the invention
It is simple that problem to be solved by this invention is to provide a kind of production technique, the production technique of good product quality and the high a kind of glass fibre of production efficiency.
To achieve these goals, the technical scheme that the present invention takes is: a kind of production technique of glass fibre, comprises following processing step:
(1) selection of raw material, comprises SiO
2, Al
2o
3, B
2o
3, CaO, MgCO
3, ZnO and TiO
2;
(2) a certain proportion of cooperation compound is modulated into by after the raw material pulverizing in step (1);
(3) compound in step (2) is added in cell furnace, after high temperature melting, make the frit of melting, form glass sphere;
(4) check, reject containing bubble or the glass sphere containing impurity;
(5) glass sphere of high-quality is re-started melting, make continuous glass fibre.
Preferably, the raw material added in described step (1) represents with weight percent: 30-50%SiO
2, 4-6%Al
2o
