Embodiment Construction
[0029] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.
[0030] refer to Figure 1 to Figure 6
[0031] A method capable of glass melting, high-temperature viscosity measurement and vertical drawing of glass fibers, the steps are as follows:
[0032]Step (1): Cut the glass sheet into 20mm~30mm square samples, use a 200ml platinum crucible to hold the glass sheet, and the lifting mechanism will slowly send the crucible into the heating furnace at a heating rate of 10°C / min. When the furnace temperature reaches 1300°C , slowly put the stirring rotor into the molten glass for stirring at a stirring speed of 20r / min to remove air bubbles, and continue to heat up to 1580°C, and keep stirring for 30min;
[0033] Step (2): According to Method A in ASTM-C965 "Standard Opera...

The invention relates to a method and system capable of glass melting, high-temperature viscosity measurement and vertical drawing of glass fibers. The steps of the method are as follows: heating and melting the glass and stirring it; testing the viscosity of the glass liquid at a specific cooling rate value; set the temperature of the glass drawn fiber according to the glass viscosity value; draw the glass fiber by the vertical upward method. The system includes a frame, on which there is a rotating platform driven by a driving mechanism. A furnace body is arranged below the rotating platform. The furnace body is divided into a heating furnace room and a holding furnace room by a partition. The crucible for placing glass samples, the crucible is driven up and down by the lifting mechanism, the partition plate is provided with a relief hole for the crucible to enter the holding furnace room, and the lower part of the rotating platform is provided with a stirring mechanism, a vertical pull-up mechanism and a viscosity testing mechanism at intervals . The method and the system can realize the testing of glass viscosity and quickly determine the suitable temperature value for the glass fiber prepared by the vertical upward method by using the tested viscosity value.
Description
technical field [0001] The invention relates to a method and system capable of glass melting, high-temperature viscosity measurement and vertical drawing of glass fibers, and is suitable for the technical field of glass materials. Background technique [0002] Glass materials should be annealed during the forming process and reprocessing process. The annealing process mainly includes the annealing limit temperature (ie, the softening point temperature), the annealing point temperature and the lower limit temperature of the annealing point (ie, the strain point temperature). The softening point temperature, annealing point temperature and strain point temperature of glass are all measured by glass fiber elongation in a heated state, and the softening point temperature Tsoftening is based on ASTM C-338 "Standard Test Method for Softening Point of Glass" Standard method measurement and GB / T 28195-2011 "Glass softening point test method", the standard requires that the glass fi...
