Abstract

The invention discloses a method for producting a superfine glass wool, which comprises the following steps of: reclaiming, washing and crushing cullet; preparing raw materials such as feldspar, dolomite, sodium carbonate and sodium borate, assaying and analyzing the components of the raw materials; counting the dosage of each raw material according to the required proportion of compound in a mixed material; weighing and mixing the raw materials and the cullet to make into the mixed material; founding the mixed material to obtain even, purified and transparent glass liquid; and guiding the glass liquid into a centrifugal machine, and fibering to obtain the glass wool. The method adopts the reclaimed waste glass as main raw material, realizes the cyclic utilization of resources, protects the environment, saves the cost, is simple in operation and not complex, and can prepare the superfine glass wool with small diameter and high flexibility.

Description

technical field [0001] The invention relates to a method for producing glass wool, in particular to a method for producing ultrafine glass wool. Background technique [0002] Ultra-fine glass wool, as a new type of fibrous receiving material, has excellent properties such as light weight, heat preservation, fire prevention, sound absorption, moth resistance, and corrosion resistance. It is widely used in chemical industry, metallurgy, light industry, electric power, petroleum and construction industries. However, at present, the production methods used for ultra-fine glass wool on the market are very complicated, and the diameter deviation of the obtained glass wool is large, and the minimum diameter of the produced ultra-fine glass wool is also 3 μm to 5 μm. This will have a strong impact on the quality of glass wool and its glass wool products, limiting the development of glass wool products. Contents of the invention [0003] Purpose of the invention: the purpose of th...
