Glass bubble a few main factors
The glass bubble, must first analyze the sources of the gases in bubble, the interaction of gas and liquid glass, glass fluid physical and chemical properties of the impact of the process of air bubbles or disappear. Glass bubble of several main factors are temperature, time, REDOX state of glass.
1. Temperature
the glass temperature of high and low, directly affects the glass liquid viscosity, surface tension, and the gas solubility in the glass.
in glass melting furnace, glass clarification process was conducted in high temperature hot area, large bubbles growing buoyancy, shrinking small bubbles and absorbed by the glass. Glass hot control method are many, the longitudinal forming longitudinal furnace temperature distribution curve of the glass to form two big circulation convection, the size of the melting rate, the rate of fluctuations, the distribution of fuel and combustion flame, glass factors such as REDOX state can significantly affect the temperature and the temperature of the hot spots of stability. In addition, bubbling technology or help fusion technology can obviously improve the use of glass hot state, promote a clarification of glass.
2. Time
glass bottles of large bubbles floatation process as well as the glass to the small bubble absorption process, must be in certain temperature range and a specific time period to complete.
some factors of the melting process, such as glass melting pool depth, bottom glass temperature, melting rate, glass liquid convection, glass REDOX state, bottom help fuse or bottom bubbling etc, can significantly affect the process of glass bubble disappear. If bubbles disappear time is not enough, eventually will remain in glass bubbles formed in the glass.
3. Glass bottle glass REDOX state
the selection of clarifying agent for glass had a greater influence on the REDOX state, clarifying agent in the process of above 1300 ℃ promote glass bubbles disappear.
in recent years, along with the people environmental protection consciousness enhancement, the improvement of glass products, developed many compound clarifying agent, due to the different function and price, choice of clarifying agent diversified enterprise.
glass COD values daily detection and control, the batch of glass in the stability of the base metal valence state control, the impact to the bottom temperature and glass REDOX state, ultimately affect the gas solubility in the glass.
The rise of the beauty economy has caused cosmetic brands to pay more and more attention to appearance packaging.

Consumer trends are the driving force of packaging innovation, and big data analysis is to combine trend insights with packaging innovation.
In order to attract consumers, in recent years, businesses have put more and more effort on cosmetic packaging, and various novel and exquisite packaging have emerged one after another.
In addition to the production date, manufacturer, etc., what are the secrets of the neglected graphic symbols, words, and numbers on the outer packaging of cosmetics?
In addition to the most common barcodes, there are some unobtrusive small icons on cosmetic packaging that also represent very important information.
This common small open can logo means the shelf life after opening.
