Embodiment 1

[0026] The wire drawing waste from the pool kiln is winding yarn. Winding yarn refers to the winding process in glass fiber, using glass fiber roving or prepreg tape under tension control to wind on a placement shaft in a predetermined arrangement, and can produce tubular or other hollow shaped products.

[0027] The steps of preparing short glass fibers by utilizing the waste winding yarns drawn from pool kilns are as follows:

[0028] (1) Coarse treatment of the waste wire drawing yarn in the pool kiln: remove 100 kg of the waste wire drawing yarn in the pool kiln to remove surface impurities such as plaster and paper scraps, and dry it in air to make the water content of the wire drawing waste wire in the pool kiln 5%;

[0029] (2) configuration of binding agent: dilute 2kg of epoxy resin binding agent with water to sprayable state, and its weight percent concentration is 15%;

[0030] (3) Spraying of binder: according to the ratio of 15:100 of the weight ratio of binder n...

Embodiment 2

[0034] Spray yarn is prepared from wire drawing waste in pool kiln. Spray yarn means that in the spray process, a spray gun is combined with a portable glass fiber roving chopping machine, the resin and glass fiber are sprayed onto the mold at the same time, and then the impregnated yarn is sprayed with a stick, brush or scraper. The glass fibers of the resin compact and allow it to cure.

[0035] The steps of preparing short glass fibers by using the waste sprayed yarns from drawing in the pool kiln are as follows:

[0036] (1) Rough treatment of waste jet yarn from drawing in pool kiln: select 100kg waste jet yarn from drawing in pool kiln according to specifications and models, remove impurities such as marl and paper scraps on the surface, and dry to make the water content of drawing waste in pool kiln 4% range.

[0037] (2) configuration of binding agent: dilute 2.5kg of polyester resin binding agent with water to sprayable state, and its weight percentage concentration...

Embodiment 3

[0042] The wire drawing waste from the tank kiln is long glass fiber for reinforced plastics. Long glass fiber for reinforced plastics belongs to untwisted roving. In the plastic extrusion granulator, in the specially designed die head, the fiber can be fully expanded to facilitate the thermoplastic resin to penetrate into the fiber and wrap the fiber.

[0043] The steps of preparing short glass fibers by using long glass fibers for reinforced plastics from pool kiln wire drawing waste are as follows:

[0044] (1) Coarse treatment of long glass fibers used in tank kiln wire drawing waste reinforced plastics: 100kg of tank kiln wire drawing waste jet yarn is selected according to specifications and models to remove impurities such as marl and paper scraps on the surface, and dried to make tank kiln wire drawing waste The moisture content of the silk is in the range of 3%;

[0045] (2) configuration of binding agent: the mixture binding agent 3kg of polyvinyl acetate and polyur...

Abstract

The process of preparing short glass fiber with waste tank furnace filament includes the following steps: initial treatment of waste tank furnace filament; compounding adhesive via diluting adhesive with water for spraying; spraying adhesive to waste tank furnace filament or soaking waste tank furnace filament in adhesive and stilling for well absorbing adhesive; forming short glass fiber through cutting, sieving and roasting. The present invention produces useful material with waste and has low production cost.

Description

technical field [0001] The invention relates to the technical field of reuse of wire drawing waste from a pool kiln, in particular to a method for preparing short glass fibers by using the waste wire drawing from a pool kiln. Background technique [0002] Generally speaking, there are two production processes in the glass fiber industry: platinum furnace wire drawing and pool kiln wire drawing. Among them, the drawing process of platinum furnace is relatively backward, and its application is less and less; while the drawing process of pool kiln is more and more widely used. Both processes generate large amounts of glass fiber waste. These waste wires are mainly composed of the hard wires produced before the upper head and the thick wires produced by the end cover of the drawing machine head. The composition of all waste silk is the same as that of glass fiber products. It belongs to silicate materials in inorganic non-metallic materials and is a non-degradable solid pollut...
