Method for producing high-zirconium alkali-resistant glass fibers from waste alkali-resistant glass fiber filaments and glass melting furnace

Abstract

The invention relates to a method for producing high-zirconium alkali-resistant glass fibers from waste alkali-resistant glass fiber filaments and a glass melting furnace, belonging to the technical field of production of alkali-resistant glass fibers. The method and the glass melting furnace are mainly used for solving the problems in the current landfill artificial-drawn waste filament treatment that the environment is polluted and the cost is increased. The method is mainly characterized by comprising the steps of: (1) selecting zirconium-containing alkali-resistant waste glass fiber filaments; (2) picking out the surfaces and inner layers of the zirconium-containing alkali-resistant waste glass fiber filaments on a platform one by one; (3) putting the picked zirconium-containing alkali-resistant waste glass fiber filaments in a vessel with flowing tap water for soaking, flipping and flushing; (4) draining, and then crushing; (5) cleaning again so as to remove a small amount of iron impurities; (6) fragmenting; (7) drying, and then, melting and clarifying; (8) flowing out of draining ports of a platinum drain board so as to form filament roots; and (9) winding the filament roots on filament tubes under the high-speed traction of a drawing machine, thereby producing crude alkali-resistant glass fiber filaments with the diameter of 10-15 microns. The method has the characteristics that the waste filaments are utilized, the pollution to the environment caused by the waste filaments is avoided, the rate of finished products of drawing is increased, and the production cost is reduced; and the method is mainly used for producing the alkali-resistant glass fibers from the waste glass fiber filaments.

Description

technical field [0001] The invention belongs to the technical field of alkali-resistant glass fiber production. In particular, it relates to a method for producing alkali-resistant glass fiber by using waste glass fiber and a special platinum substitution furnace. Background technique [0002] During the production process of alkali-resistant glass fiber, a large amount of human-drawn waste will be generated. At present, the treatment of human-drawn waste is basically done by landfill. There are following deficiencies in the disposal mode of this landfill people pulling waste silk, the one, pollute environment; The 2nd, increase cost. Since the waste silk produced in the production process of alkali-resistant glass fiber contains iron and other impurities, it is impossible to use the waste silk to produce alkali-resistant glass that meets the use standards by using existing or properly modified melting furnaces and existing production processes fiber. It is a problem that...
