Reasons for the formation of air bubbles in the production process of glass bottles

Glass bottles are produced using molds. Different types of molds can produce glass bottles of different shapes. After some glass bottles are produced, due to quality reasons, bubbles will appear on the bottle body. The larger the capacity of the glass bottle, the more clearly it will be reflected. , how do the bubbles in these glass bottles form?

When the glass bottle is melted, all the salts in the material will be decomposed at high altitude, and a large amount of gas will be continuously removed from the melt. The melt needs to continue to eliminate air bubbles when it enters the clarified place. In order to increase the speed of dispelling bubbles, high temperature melting is usually used to reduce the viscosity of the glass liquid, and substances that reduce surface tension are added, and the pressure in the kiln is reduced to make the bubbles pop out quickly. However, despite this, some bubbles will still remain in the molten glass, and bubbles will appear after it interacts with the furnace gas, but they are not eliminated as soon as possible, thus forming residual bubbles.

In order to prevent the quality of glass bottles from bubbles, the valiant group strictly follows the ingredients and melts the regulations, and also adjusts the degree of melting to improve the type and time of clarification, and also finds out the composition of glass bottles in a timely manner. , so that the viscosity of the melt and the surface tension of the melt are reduced, which will effectively prevent the occurrence of bubble quality problems in the glass bottle.
