The formula of high flint glass bottles

High flint glass bottles, also called crystal white glass bottles. Different olfactory has different formulas for it, and all keep it secret. But the mainly raw material is the same.

Today I will tell you one of the formula for the high flint glass bottles.

The rate of the contents in the high flint glass bottles is 20% cullet and 80% mixed batch. And the mixed batch including 51% - 54 % quartz sand, 8% -10% feldspar, 7% -9% calcite, 1% -2% fluorspar, 14% -16% sodium carbonate, 5% - 8% dolomite, 0.65% - 0.81% salt, some selenium powder and cobalt powder. And the rate of selenium powder and cobalt power is optional.  

Using this formula can make improve the glass bottles’ appearance quality and physical and chemical property. It’s also can reduce the furnace melting temperature, reduce the energy consumption. This is very friendly for the environment.

The high flint glass bottles can show the quality of products inside as its high transparency. The glass bottles are very clear, without any impurity, and it looks fancy.

There are many kinds of high flint glass bottles, and which bottles are suit for high flint material in the production? There are wine bottles, beverage bottles, juice bottles, cooking oil bottles, olive oil bottles, camellia oil bottles, water bottles and so on.

This high flint glass bottles are suitable for fully automated mass production. The rsglassbottle.com has invested 2 production lines of the most advanced 8S fully automatic machine for making the high flint glass botles. Its production scale is the moderate and production technology is mature, very suitable for mass production in any batches.

The processing of high flint glass bottles as following: The silica sand, soda ash, limestone, and others raw material are weight and mixing with a definite proportion in the batch plant, then send them by the transport equipment to the hopper at the melting furnace. The mixed raw materials will become glass melt under the 1,550^oC in the melting furnace. The glass melt will be sent to the glass bottle - forming machine via the feeder and will be shaped according the designed bottle shape. After the bottle is shaped, them will enter the annealing furnace to annealing the bottles.

The heat treatment of flint glass bottles is through the annealing,  quenching and other processes to eliminate or produce the internal stress of the glass bottles, split or crystallization, and change the structure of the glass bottles state. The high flint glass bottles are soda-lime glass bottles, they are very friendly for the enviroment, more and more people love them. 

The chemical and physical composition of different glass bottles

Different composition can make different glass, and different glass can make different glass bottles.Today I will tell you the chemical and physical compostion of different glass bottles.

According the mainly composition of glass, the glass bottles usually be divided into oxide glass bottles and nonoxide glass bottles.

About the nonoxide glass, there are extremely rare in the types and quantities. The nonoxide glass are including chalcogenide glass bottles and halide glass . Most of the anions of chalcogenide glass are sulfur, selenium, tellurium and so on, they can cut offer short wavelength light and through the yellow, red, and near, far infrared light. Their resistance is low, with the characteristics of switching and memory. The halide glass with low refractive index, low dispersion, widely used as optical glass.

About the oxide glass , they are divided into silicate glass , borate glass , phosphate glass and so on. The silicate glass refers the glass bottle which basic composition is SiO₂, they are used for a widely range. 

Usually according to the SiO2 and alkali metals, alkaline earth metal oxides of different content in the glass, the glass is divided into: quartz glass, high silica glass, soda-lime glass, lead silicate glass, aluminosilicate glass, borosilicate glass and so on.

1. Quartz glass. The content of SiO₂ is more than 99.5%. It’s has low coefficient of thermal expansion, high temperature resistance, chemical stability, through the ultraviolet and infrared light, high melting temperature, big viscosity, difficult to shape. They are used for semiconductors, electric light sources, optical communication, laser and other technologies and optical instruments.

2. High silica glass. The content of SiO₂ is about 96%. Its property is similar as the quartz glass.

3. Soda- lime glass. The main components of soda-lime glass is SiO2, and also has 15% Na₂O and 16% CaO. As their cost is low, easy to shape, its suit for mass production. Its production accounted for 90% of practical glass. The glass can be used as glass bottle jar, glass bulb and so on. The glass bottles manufactory rsglassbottle.com usually use this glass to make all kinds of glass bottles, glass jar, glass container and so on. 

4. Lead silicate glass. The main components of lead silicate glass is SiO₂ and PbO. It can be used as glass bulb, crystal glass container, and so on as it with high refractive index and high volume resistance, and the metal has a good wetting.

5. Aluminosilicate glass. Its main components is SiO₂ and Al₂O₃. It can be used for bulb, High temperature glass thermometer, Chemical combustion tube and so on.

6. Borosilicate glass. This glass main components is SiO₂ and B₂O₃. It’s has good heat resistance and chemical stability, can be used for cooking utensils and so on.

The above are the different glass bottles with physical and chemical composition. If you want to know more information, welcome to contact with us.

• The main process specification

Generally speaking, the main production workshop of glass bottle manufactory is including ingredients workshop, melting workshop (including furnace), broken glass processing workshop, machine repair workshop, raw materials workshop, packaging materials workshop and so on. And with a complete set of public works there is a gas station (heavy oil, gas pressure regulating station), air compressor station, transformer room, water pumping stations, sewage treatment station, platform and services facilities, dormitory, Office, dining room, bathroom and other monomers.

The processing of making the glass bottles should as bellowing: The silica sand, soda ash, limestone, and others raw material are weight and mixing with a definite proportion in the batch plant, then send them by the transport equipment to the hopper at the melting furnace. The mixed raw materials will become glass melt under the 1,550^oC in the melting furnace. The glass melt will be sent to the glass bottle - forming machine via the feeder and will be shaped according the designed bottle shape. After the bottle is shaped, them will enter the annealing furnace to annealing the bottles. After annealing in the lehr, the glass bottles is strictly checked on automatic inspection machine and visually inspect each bottle to confirm quality by skilled technicians. The glass bottles will be packing and shipment if the bottles are meeting the requirements.

(1) Batch plant: In this plant, there is generally has a warehouse for the all kinds raw mateiral, lifting equipment, weighing equipment, mixing equipment and so on. Its work is to weighting and mixing the mineral and chemical materials with proporation become to glass batch. The mainly raw materials of glass bottles are quartz sand, sodium carbonate, borax, broken glass and so on.

(2) Melting plant: This plant is the main production workshop for the glass bottles. In generally speaking, there are glass melting furnace, forehearths, bottle-shape machine, annealing furnace, inspection, packing and shipment and so on. At present, the workshop generally uses two layers (three layers of local) layout, forming equipment (bottle machine), annealing furnace, inspection and packaging equipment placed on the second floor.

• The processing technique of glass bottles

The processing technique of glass bottles as bellowing

1. The pre-processing of raw materials. Frist, we should make the block raw material ( such as quartz sand, sodium carbonate, limestone, broken glass and so on) to power. Dry the damp materials, and remove the iron from the raw meterials. This step is very important, it’s make sure the glass bottle quality.

2. The making of glass batch. The right glass batch can make the good glass bottles.

3. The melting of glass melt. The glass batch in the kiln or furnace for high temperature heating, so that the glass batch become the liquid glass with uniform, no bubbles and meeting the molding requirements.

4. Shape the glass bottles. The liquid glass enter the bottle mold, and shape the glass bottles according the mold.

5. Heat treatment. Through the annealing, quenching and other processes to eliminate or produce the internal stress of the glass bottles, split or crystallization, and change the structure of the glass bottles state.
