Glass bottles are produced using mold shapes. Different types of molds can produce glass bottles of different bottle shapes. After some glass bottles are produced, due to quality reasons, bubbles will appear on the bottle body. The larger the volume of the glass bottle, the more clearly it will be reflected. , How did the bubbles in these glass bottles form?
When the glass bottle is melted, all the salts in the material will be decomposed at a high level, and a large amount of gas generated is continuously removed from the melt. The melt needs to continue to debubble 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 the surface tension are added, and the pressure in the kiln is reduced to make the bubbles emerge quickly. But despite this, some bubbles will still remain in the molten glass, and the bubbles appear after the mutual effect between it and the furnace gas but they are not removed as quickly as possible, thus forming residual bubbles.
In order to prevent the quality of the bubbles in the glass bottles, the glass bottle manufacturers strictly follow the regulations of the ingredients to be melted, and adjust the melting degree to improve the type and use time of the clarifying agent, and also clarify the modification of the glass bottle in a timely manner. The composition of the melt reduces the viscosity of the melt and the surface tension, which will effectively prevent the occurrence of bubble quality problems in the glass bottle.
