Glass Bottle Production Four Steps

Oct. 24, 2019

Glass bottles, from large bottles to small bottles, are widely used in food, medicine, beverage and other packaging containers. The glass bottle factory pointed out that it can be recycled and reused, and it is a very safe and environmentally friendly packaging container. What is the main production step of glass? A Glass Bottle With Cork Suppliers will come to tell everyone.

The ingredients of the glass bottles are weighed according to the designed materials, and the various raw materials are weighed and mixed evenly in a mixing machine. The main raw materials of glass are: quartz sand, limestone, feldspar, soda ash, boric acid and the like. Glass bottles are highly transparent and resistant to corrosion and do not change in material properties when in contact with most chemicals. The manufacturing process is simple, the shape is free and changeable, the hardness is large, heat-resistant, clean, easy to clean, and has the characteristics of being reusable. Glass bottles are widely used as packaging materials for food, oil, alcohol, beverages, condiments, cosmetics, and liquid chemical products. However, glass bottles also have their shortcomings, such as heavy weight, high transportation and storage costs, and low impact resistance.

The glass bottle is melted, and the prepared raw materials are heated at a high temperature to form a uniform bubble-free glass liquid. This is a very complicated physical and chemical reaction process. The melting of the glass takes place in the furnace.

The glass bottle is formed by converting the molten glass into a solid product having a fixed shape. Forming must be carried out within a certain temperature range. This is a cooling process in which the glass first changes from a viscous liquid state to a plastic state and then to a brittle solid state.

Annealing of the glass bottle, the glass undergoes intense temperature changes and shape changes during the forming process, which changes the thermal stress in the glass. This thermal stress reduces the strength and thermal stability of the glass article. The glass bottle factory pointed out that if it is directly cooled, it is likely to break itself during storage or transportation during the cooling process or later (commonly known as the cold explosion of glass).

General glass bottles are common terms, and they contain many types. The color of glass bottles is roughly divided into: blue, white, high white, white, crystal and so on. The varieties of glass bottles include honey glass bottles, pickles glass bottles, Glass Juice Bottles For Canning, canned glass bottles, wine bottles, health wine bottles, yogurt glass bottles, vases, and the like. Some bottles can be used interchangeably like glass bottles filled with honey to hold pickles, some can not be used interchangeably, can not be canned like wine bottles and so on. From small bottles of 1ML to large bottles of dozens of liters, from round, square, to shaped and handle bottles, from clear, amber, green, blue, black shaded bottles and opaque opaque glass bottles Wait, there are too many to do.

Let's talk about the use characteristics of glass bottles: glass bottles are the main packaging containers for food, medicine and chemical industries. They have good chemical stability; easy to seal, good air tightness, transparent, can be observed from the outside; the storage performance is good; the surface is smooth, easy to disinfect and sterilize; the shape is beautiful, the decoration is colorful; there is certain machinery The strength can withstand the pressure inside the bottle and the external force during transportation; the raw materials are widely distributed and the price is low. The disadvantage is that the quality is large (the mass to capacity ratio is large), the brittleness is large, and it is brittle. However, in recent years, the use of thin-walled lightweight and physical chemical tempering new technologies, these shortcomings have been significantly improved, so glass bottles can compete with plastics, porcelain cans, iron cans, the output is increasing year by year.

The above is about the production steps and characteristics of glass bottles. If you have a need for glass bottles, you can contact us, we can provide you with a variety of bottles including Glass Milk Bottles, welcome you.
