Glass should be the best packaging

Glass is one of the earliest human invention of artificial materials, is a kind of transparent, high strength and hardness, airtight material. Glass in the daily environment shows chemical inertness, also won't and biological effect, it USES a very wide range.

life with glass is generally belongs to the soda lime glass, quartz sand, soda ash, feldspar, limestone and other ingredients.

glass production technology mainly includes: (1) the raw material preparation. The massive materials ( Quartz sand, soda ash, limestone, feldspar, etc. ) Shattered, damp raw material is dry, will be in addition to iron iron raw material processing, to ensure the quality of glass. (2) material preparation. (3) melted. Glass batch or crucible furnace in pool kiln 1550 ~ 1600 degrees high temperature heating, forming uniform, no bubble, and meet the requirements of the molding liquid glass. (4) shape. The liquid processed into the required shape of glass products, such as tablets, all kinds of vessels, etc. (5) heat treatment. Eliminated by annealing, quenching, such as technology, or producing glass internal stress, split phase or crystallization, and the structure of glass state.

glass bottle is transparent, because of its transparent beauty and reliable chemical stability and barrier property ( With no pollution) As a packaging container, can be high temperature heating, is one of the safest and the most excellent; Green environmental protection advantages of glass can be recycled, waste glass bottle recycling renewable utilization of advantages, has been acknowledged as the best packaging material in the world.

the related research institutions have annual per capita use glass volume as a measure of an important symbol of national civilization degree.

household glass use and consumption per capita in China is quite low compared with the international developed countries, Europe and the United States developed countries use and consumption per capita annual household glass in 50 kilograms, while only about 10 kg per capita. Calculated from the aspects of consumer prices in China use and consumption per capita is less than 100 yuan a year, with Europe and the United States than in some countries, gap in ten times or even dozens of times. China's current production of a wine glass price only a few yuan or ten yuan, European and American countries produce similar glass to hundreds or even thousands of yuan.

weakness of glass is easily broken, the glass bottle production enterprises are taking technology to the production process of glass bottles and equipment modification in order to make the use of glass bottles is more convenient and safe.

glass has been the People's Daily necessities, some become works of art on table, some necessary become family adornment, some used to beautify the body, some become self love collection.

glass as the packing materials. Can make the person & ndash; — Delicious, delicious visible visibility, happy and health.
