Abstract

The invention provides a production process for microfiber glass wool. The production process is characterized by comprising the following steps: recovering waste glass, cleaning and crushing the waste glass until the diameter of the waste glass is less than 30 mm and preparing feldspar, sodium carbonate and borax, wherein the percentages of the above-mentioned raw materials are that feldspar 10 to 15%, sodium carbonate 3 to 4%, borax 9 to 10% and the waste glass 71 to 80%; weighing the raw materials according to the percentages and mixing the raw materials so as to prepare a mixture; fusing the mixture to obtain uniform, pure and transparent molten glass; guiding the molten glass to a wire drawing bushing plate for wire drawing, wherein drawn wires are guided into flames produced by an injection combustor of an injection combustion chamber; and preparing microfiber glass wool with a diameter of 0.5 to 2 mu m from the glass wires by using flames produced by the injection combustor. According to the invention, the production process for the microfiber glass wool is simple and utilizes the waste glass to produce the microfiber glass wool with light weight and a uniform diameter, thereby realizing cyclic usage of resources and conservation of production cost.

Description

A kind of micro-fiber glass wool production technique

Technical field

The present invention relates to glass wool manufacture craft, particularly relate to a kind of micro-fiber glass wool production technique.

Background technology

Micro-fiber glass wool, it has light weight, insulation, fire prevention, sound-absorbing, mothproof, antiseptic property, be widely used in chemical industry, metallurgy, light industry, electric power, oil and building trade, but the production method of micro-fiber glass wool is very complicated at present, glass wool diameter deviation is large, have a strong impact on the quality of glass wool and glass wool goods, limited the development of glass wool goods.

Summary of the invention

The technical problem to be solved in the present invention is to provide a kind of production simple, and utilize cullet to produce light weight, the uniform micro-fiber glass wool production technique of diameter.

The technical scheme adopting is:

A production technique, this production craft step is as follows:

(1) reclaim cullet, clean, be broken into diameter and be less than 30mm, prepare feldspar, soda ash, borax;

(2) starting material batching per-cent: feldspar 10 ~ 15%; Soda ash 3 ~ 4%; Borax 9 ~ 10%; Cullet 71 ~ 80%.

(3) by batching per-cent, take raw material and cullet, and mix, make compound;

(4) by compound fusing, obtain even, pure, transparent glass metal;

(5) glass metal is directed to bushing wire drawing, its wire drawing causes in the flame of blowing burner ejection of jet combustors;

(6) with the flame of blowing burner ejection, glass yarn is made to the micro-fiber glass wool of 0.5-2 μ m.

The micro-fiber glass wool that the present invention makes, produce simple, and utilize cullet to produce light weight, diameter is even, realizes resource circulation utilization, save production cost, the development of favourable glass wool goods.
