Some bottles shake too much. They don't explode when they are placed on the ground, and it's hard to say that they will explode in a day or two.
The main reason is that the gas (carbon dioxide) is added to the beer beverage, which has a certain pressure. If the beer bottle is not very strong, the pressure inside will be released and cause an explosion.
There are many factors in the explosion of beer bottles. First, the recycled bottles are out of service. The national regulations prohibit the production and sale of non-B bottles of beer, and suggest that the recycling period of B bottles is two years. However, at present, there are still non-"B" bottles and a large number of "B" bottles that have been out of service in the circulation market. The service life of beer bottles is too long, which is easy to cause scratches, scratches and aging of materials, resulting in a decrease in pressure resistance. Therefore, the probability of detonation of B bottles that exceed the normal service life will greatly increase.
In addition, the poor quality of ordinary beer bottles is also an important factor. Judging from the situation reflected by consumer complaints, the explosion accidents of beer bottles are all concentrated in ordinary beer bottles, and hardcover beer rarely explodes. The reason is that some manufacturers have bought B bottles with low quality and low price in order to save costs.
Unreasonable transportation and storage methods are also a major reason. Some beer production enterprises pack beer in bundles, which leads to violent collision in the transportation of beer bottles, which greatly reduces the mechanical strength of beer bottles and causes hidden cracks. If the beer is improperly stored, if the temperature is too high or exposed to the sun, the gas in the bottle will expand and the air pressure will be too high, and an explosion may occur. The rapid cooling speed of beer and the sudden change of temperature difference cause the pressure resistance of the bottle to drop, and careless collision is also easy to lead to explosion.
