Embodiment 1

[0020] A method for eliminating microbubbles in glass, comprising the steps of:

[0021] (1) Spraying: Pour butyl orthotitanate into the glass cylinder, use a small pump to extract the butyl orthotitanate from the glass cylinder, and spray it evenly to the liquid surface of the glass clarification zone through the nozzle, when the butyl orthotitanate Stop spraying when the ester is covered with the liquid surface in the glass clarification zone;

[0022] (2) Second spraying: After spraying for 15 minutes, observe whether the glass clarification area still contains an organic silicon layer, if it still contains an organic silicon layer, repeat step (1), and continue to spray butyl orthotitanate on the liquid surface of the glass clarification area ;

[0023] (3) Observation: When the silicone layer disappears on the liquid surface in the glass clarification area, stop spraying and observe the changes in the density of bubbles every two hours. When the density of bubbles decrea...

Embodiment 2

[0032] (1) Spraying: Pour butyl orthotitanate into the glass cylinder, use a small pump to extract the butyl orthotitanate from the glass cylinder, and spray it evenly to the liquid surface of the glass clarification zone through the nozzle, when the butyl orthotitanate Stop spraying when the ester is covered with the liquid surface in the glass clarification zone;

[0033] (2) Second spraying: After spraying for 17 minutes, observe whether the glass clarification area still contains an organic silicon layer, if it still contains an organic silicon layer, repeat step (1), and continue to spray butyl orthotitanate on the liquid surface of the glass clarification area ;

[0034] (3) Observation: When the organic silicon layer disappears on the liquid surface in the glass clarification area, stop spraying and observe the bubbles floating up every 2 hours. When the number of bubbles floating up is significantly reduced or the organic silicon layer is visible to the naked eye, repe...

Embodiment 3

[0043] (1) Spraying: Pour butyl orthotitanate into the glass cylinder, use a small pump to extract the butyl orthotitanate from the glass cylinder, and spray it evenly to the liquid surface of the glass clarification zone through the nozzle, when the butyl orthotitanate Stop spraying when the ester is covered with the liquid surface in the glass clarification zone;

[0044] (2) Second spraying: After spraying for 20 minutes, observe whether the glass clarification area still contains an organic silicon layer, if it still contains an organic silicon layer, repeat step (1), and continue to spray butyl orthotitanate on the liquid surface of the glass clarification area ;

[0045] (3) Observation: When the organic silicon layer disappears on the liquid surface in the glass clarification area, stop spraying and observe the bubbles floating up every 2 hours. When the number of bubbles floating up is significantly reduced or the organic silicon layer is visible to the naked eye, repe...

Abstract

The invention discloses a method for eliminating microbubbles in glass. The method comprises the following steps: (1) performing spraying: pouring tetrabutyl titanate into a glass cylinder, pumping the tetrabutyl titanate out from the glass cylinder by using a small-scale pump to be uniformly sprayed to a liquid surface in a glass clarification zone by a spray nozzle, and stopping spraying when the tetrabutyl titanate is completely spread the liquid surface in the glass clarification zone; (2) performing secondary spraying: after spraying is performed for 15-20 min, observing whether the glassclarification zone still contains an organosilicone layer, if the glass clarification zone still contains the organosilicone layer, repeating the step (1), and continuing spraying the tetrabutyl titanate to the liquid surface in the glass clear zone; and (3) performing observing: when the organosilicone layer of the liquid surface in the glass clarification zone disappears, stopping spraying, observing bubble density change every two hours, and when a bubble density is significantly reduced or the organosilicone layer is macroscopic, repeating the step (1) and (2). The method provided by theinvention well eliminates the organosilicone foam layer by adopting the manner that the organic material tetrabutyl titanate capable of reacting with the organosilicone layer is sprayed from the clarification zone, thereby eliminating the microbubbles.

Description

technical field [0001] The invention relates to the field of glass production, in particular to a method for eliminating microbubbles in glass. Background technique [0002] Due to SiO 2 It is the main raw material necessary for glass production, generally accounting for about 70%. Long-term use will produce a layer of organic silicon on the liquid surface in the glass clarification area, which prevents the floating and release of microbubbles. [0003] High-quality glass products have relatively high requirements for micro-bubbles in the glass. For example, lead-free imitation crystal glass requires no bubbles larger than 0.1 mm. [0004] In order to eliminate the micro-bubbles in the glass, the general process is: increase the melting and clarification temperature, reduce the viscosity of the glass liquid, increase the amount of clarifier, and eliminate the micro-bubbles. [0005] On the one hand, these methods will increase the production cost of the glass factory; on t...
