Many beverages (including beer, sparkling wine, etc.) contain carbon dioxide co2, also called carbonated gas. Carbon dioxide is carbonic acid when it is soluble in water, which is very weakly acidic. Carbon dioxide is slightly soluble in water under conventional conditions, which means that it is very soluble. The amount of CO2 dissolved in the production of CO2 is greatly increased under pressurized conditions. The pressure of beer is generally higher than that of soft drinks, so Beer bottles are pressure vessels and have special specifications. No one has seen beer in plastic bottles. This is why beer bottles are more valuable than liquor bottles. Carbonated beverages such as cola use ordinary containers, which of course must be acceptable. pressure. What we call "shaking vigorously" actually changes the pressure balance in the container, forming a large amount of carbon dioxide gas to escape. When a good bottle of beer is opened, foam will be sprayed, and it is also because of changes in pressure that cause carbon dioxide to escape. Some people open the beer and see the spray and quickly cover it. This is dangerous. You can only hope that the beer bottle is fully qualified, otherwise it may explode. Of course, the increase in temperature will also reduce the solubility of carbon dioxide, causing the gas to escape.
Because beer contains organic ingredients such as alcohol, and the plastic in plastic bottles is organic. These organics are harmful to the human body. According to the principle of similarity and compatibility, these organics will dissolve in beer. When people drink such beer, they will also be toxic. Organic matter is ingested into the body, thus causing harm to the human body.
Beer bottles must be pressure-resistant and fresh-keeping due to the special nature of beer, so beer bottles are generally dark-colored bottles, and glass bottles have better fresh-keeping performance and pressure resistance than plastic bottles, so glass bottles are currently used. , Now there are plastic bottles (pet beer bottles), not many due to technical reasons. Of course pet is a safe and non-toxic plastic product. The company mainly produces automatic blow molding machines, plastic blow molding machines and other products, welcome to buy.
