Problems solved by technology

In the past, the fillers used were alumina powder solution or alumina hollow sphere solution, which are prone to precipitation effect, and after sintering, the top is loose and the bottom is dense, which affects the uniformity of the temperature distribution of the platinum delivery device
If water is not added to these two fillers, and only alumina powder or alumina hollow balls are used, the sintering temperature will be too low or sintering will not be possible.

Embodiment Construction

[0032] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0033] see figure 1 , the present invention comprises platinum conveying device 101, and the periphery of platinum conveying device 101 is provided with thermal insulation material 102, and thermal insulation material 102 carries out support and heat preservation; Leave the gap of 5~50mm between platinum conveying device 101 and thermal insulation material 102, add in this gap ZrO 2 The filling material 103 is based, wherein the filling material 103 is first dried at 100-140° C. for 3-5 hours to remove moisture; then added to the gap and sintered at 1100-1600° C. for 2-4 hours.

[0034] In terms of mass percentage, the filling material includes ZrO 2 : 50~80%, Al 2 o 3 : 3~15%, SiO 2 : 10-30%, water glass: <10%, of which the Baume degree of water glass is 9.9-45°Bé, which is liquid and easy to flow, so that the filling material can penetrate into the gap...

Abstract

The invention relates to a platinum delivery device for electronic glass manufacturing, as well as a preparation method and a filling material of the platinum delivery device. The filling material comprises the following substances in percentage by weight: 50 to 80 percent of ZrO2, 3 to 15 percent of Al2O3, 10 to 30 percent of SiO2 and less than 10 percent of water glass. The filling material is added into a gap between the platinum delivery device and a heat-preservation material, and because the filling material is in a loose state at 1,100 DEG C or less, and is free of sintering, the expansion of platinum is facilitated, and the service life of the platinum delivery device is prolonged; the sintering of the filling material is started from 1100 EDG C, and the filling material can be completely sintered at 1,600 DEG C,, so that volatilization loss after the oxidation corrosion of a platinum material is reduced; in addition, sintering uniformity is ensured, so that temperature distribution in the platinum delivery device is uniform, the quality of glass is effectively improved, and the application range is wide.

Description

technical field [0001] The invention relates to the field of electronic glass manufacturing, in particular to a platinum conveying device for electronic glass manufacturing, a preparation method and a filling material thereof. Background technique [0002] In the manufacture of electronic glass, during the heating process of the platinum delivery device, the platinum will expand and its strength will decrease. If it comes into direct contact with the insulation material, it will cause damage to the platinum delivery device. Therefore, there should be a certain gap between the platinum delivery device and the thermal insulation material to buffer and protect its expansion, while avoiding direct contact between the device and the thermal insulation material. [0003] During the manufacturing process of glass, the water in the molten glass is decomposed at high temperature, and the hydrogen ions (H + ) overflows through the platinum medium, while the oxygen ions (O 2- ) is en...
