With the development of market economy, in the use of glass bottles is more and more big, began to shift from past furniture food to handicrafts, ornaments, such as glass technology is improving little by little every day, light, environmental protection is the development trend, however, the bottle burst problem has always been a difficulty in glass bottles suppliers, how to reduce the burst rate is also a basic standard in production.
1. When the pressure in the bottle is too large, a certain amount of carbon dioxide will be released at too high a temperature. When the gas in the glass bottles suppliers reaches a certain amount in the closed container, it will press the inner wall of the package, and the blasting problem will occur when it exceeds the bearing capacity.
2, thermal shock, high temperature sterilization process and then cooling process glass bottles have experienced high and low temperature sudden change, better than the non-uniformity of glass bottles caused by the difference between thermal expansion and contraction, easy to cause broken bottles, glass bottle thermal shock tester RCY-02 glass bottle thermal shock test instrument.
3, internal stress, stress that exist in a glass bottle has the thermal stress and structural stress, thermal stress in glass production process after secondary annealing can eliminate, structural stress in the process of annealing annealing cannot be eliminated, it will forever keep in glass products, glass products by itself in the structure stress if more than able to withstand the mechanical strength, Products will not produce rupture, the difference between glass bottles custom-made structure stress and thermal stress method is the annealed products, using YLY-02 polarizing stress meter inspection, first measured the original stress size, and then put the products in the boiler for precision annealing, if after precision annealing, the stress is still not eliminated, At this time, the stress retained in the product can be considered as the structural stress caused by the uneven chemical composition of glass caused by the uneven melting of glass.
