Embodiment approach

[0010] A method for producing ultrafine glass wool, the wool is composed of carbon dioxide and boron trioxide, characterized in that the diameter of the glass wool is less than 2.0 microns. The cotton production method is to heat the raw material to 1200°C ± 80°C and draw it into glass filaments with a diameter of 150 microns to 400 microns, and use a flame of 1560°C to 1980°C to blow the glass filaments when the spray speed is greater than 610 m / s. glass wool.

Abstract

The invention belongs to the field of a superfine glass wool and a manufacturing method thereof. The wool comprises carbon dioxide and boron trioxide, and the diameter of the wool is less than 2 micrometers. The manufacturing method comprises the following steps of: jetting raw materials with the diameter of 150 micrometers to glass silks with the diameter of 400 micrometers by using flames at 1560 DEG C and 1980 DEG C, and then forming the superfine wool when the jetting speed is greater than 610m / s. The superfine glass wool has the advantages of superfine form, uniform diameter, fire protection, sound absorption, heat preservation, insulation and low cost.

Description

1. Technical field: [0001] The invention belongs to the field of glass wool and its production, in particular to an ultrafine glass wool and its production method. 2. Background technology: [0002] At present, there are many glass wool and its manufacturing methods, but there are very few ultra-fine glass wool. In the original production process, there are many additives in the raw materials of the product, and the cost is high. The processing can only be completed by multi-step methods. Fire prevention, insulation, heat preservation, sound absorption, etc., have not been applied to civilian fields. 3. Contents of the invention: [0003] 1. The present invention overcomes the above-mentioned deficiencies, adopts a precise production process control method, and invents and manufactures ultra-fine glass wool cloth with a diameter of less than 2 microns. The production cost is very low, the product has a wide range of applications, and the product has good hand feeling, whit...
