    Polarizing stress meter to solve the problem of broken glass bottles Glass bottle packaging is a common form of packaging in drug packaging, especially for injection drugs, such as ampoules, infusion bottles, control molded glass bottles, etc., which are basically packed with glass bottles It is mainly because of the chemical stability and excellent mechanical properties of glass containers However, the glass bottle is easy to produce internal stress in the process of production The stress refers to that when the glass is deformed due to external factors (stress, humidity, temperature field change, etc.), it needs to use the internal stress detector of the glass bottle for detection, In order to resist the effect of external factors, the internal forces of interaction between the parts in the glass are produced, and the glass is tried to recover from the position after deformation to the position before deformation Therefore, the glass bottle manufacturers usually use annealing treatment after the glass bottle is formed to heat and cool the glass bottle again to eliminate the residual stress However, even after annealing treatment, a part of internal stress will remain in the glass bottle, which usually exists at the bottom edge or shoulder of the glass bottle, and often causes the glass bottle to break in the process of filling or transportation The stress in the glass bottle is generally divided into thermal stress, structural stress and mechanical stress It can be tested with yly-05 glass bottle polarizing stress meter produced by Jinan Saicheng Jinan Saicheng analyzes the causes of various stresses: thermal stress is caused by temperature gradient This is because glass is a kind of amorphous product solidified by high-temperature melting and rapid cooling, so in the production process, the temperature change of each part of the glass bottle can not be uniform, so it will generate thermal stress The thermal explosion of glass is caused by too much thermal stress; the impact fracture of glass is caused by too much mechanical stress of glass bottle caused by mechanical impact force or impact force; the self explosion of glass is caused by too much internal stress of glass yly-05 glass bottle polarizing stress meter Test principle: an instrument used to check the internal stress of glass or the birefringence effect of crystal by the interference principle of polarized light Because the instrument is equipped with sensitive color plate and uses 1 / 4 wave plate compensation method, the instrument can not only measure the internal stress of glass qualitatively or semi quantitatively according to the interference color sequence in polarization field, but also accurately and quantitatively measure the internal stress value of glass (for more details, please consult Jinan Saicheng instrument)
