Bubbles appearing on the glass bottle is a flaw in the appearance, which greatly affects the appearance and is a serious quality problem. Therefore, it is not allowed to appear bubbles on the glass bottle during production. What is the reason? The bubbles appearing on the glass bottle can effectively avoid the generation of bubbles during production.
In fact, there are many reasons for the bubbles on the glass bottle:
First, reboiling bubbles, that is, after the glass solution is clarified, the composition of the gas medium in the kiln changes, and the temperature of the glass liquid fluctuates at a certain time, and the decomposed gas will be precipitated from the clarified glass. This gas is in the glass. The bubbles formed are called reboiling bubbles (or secondary bubbles, regenerative bubbles);
Second, the electric heating furnace produces air bubbles, most of which are caused by electrode oxidation, the operation of feeding materials and the corrosion of refractory materials by glass, which cause external air bubbles, and the glass bottle itself is melted, which comes from the formation of batch materials;
Third, refractory material bubbles refer to the chemical and physical effects of refractory materials and glass to produce bubbles; fourth, metallic iron bubbles refer to the use of machinery, ironware, molds and other iron materials falling into glass bottles during the operation process. , Gradually dissolved, the carbon contained in the iron interacts with the gas in the glass to generate bubbles.
Fourth, stirring bubbles refer to the bubbles generated by stirring the glass bottle liquid at a static temperature or under the action of a feeder. Fifth, post-processing bubbles refer to the bubbles generated by heating and heating glass bottles after secondary processing
