Description
Technical field
The present invention relates to a kind of devices and methods therefor reducing glass melt viscosity, especially relate to a kind of devices and methods therefor reducing bushing place, centrifugal cotton molten bath glass melt viscosity.
Background technology
Centrifugally glass-wool take glass cullet as main raw material, through fusing, homogenizing and clarifying treatment in high temperature melting furnaces, then glass melt is flowed out by the bushing place in molten bath, enters the centrifugal pan of high speed rotating, by centrifugal action, glass melt is thrown away and makes centrifugally glass-wool.
The diameter of current domestic centrifugally glass-wool is generally more than 7-8 micron, and the heat preservation and insulation of glass wool product is poor.Research shows, Fibre diameter often reduces 1 micron, and thermal conductivity value can reduce by 9.2%.And glass melt viscosity is the most important factor affecting centrifugally glass-wool Fibre diameter, the viscosity of glass melt is lower, and Fibre diameter is more tiny.
The conventional art of current centrifugally glass-wool is the temperature by raising glass melt, reduce the viscosity of glass melt, thus obtain the tiny centrifugal cotton of Fibre diameter, but this method can cause the reduction in centrifugal pan life-span, the increase of production energy consumption, does not meet the policy that national energy-saving reduces discharging.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of device reducing bushing place, centrifugal cotton molten bath glass melt viscosity, comprise molten bath, glass melt, bushing, platinum electrode slice, alternating source device, it is characterized in that placing two platinum electrode slices above bushing, electrode slice is by the external alternating source device of wire.
Another technical problem to be solved by this invention is to provide a kind of method reducing bushing place, centrifugal cotton molten bath glass melt viscosity, is realized by following steps:
(1) fixed placement two platinum electrode slices above bushing, electrode slice is by the external alternating source device of wire;
(2) relation bushing, waits for that the glass melt of front end high temperature melting, homogenizing and clarifying treatment is full of molten bath;
(3) open alternating source device, setting output voltage and output frequency, produce alternating electric field between two electrode slices;
(3) after certain hour, open bushing, glass melt is flowed out from bushing, enters the centrifugal pan of high speed rotating.
Method described above, it is characterized in that output voltage is 220-380V, output frequency is 50-5000Hz, and certain hour is 5-10 minute.
The invention has the beneficial effects as follows and a kind of devices and methods therefor reducing glass melt viscosity is provided, utilize alternating source to produce alternating electric field between two platinum electrodes; Polymer-based group [SiO in glass fluxed melt
