Description:

Is it a beer glass bottle ? No,this is a glass bottle to store soft drink. From its shape,you could definately think that it is a beer bottle,however,you could double check its mouth,it is belong to the type of screw,if it was a beer bottle,then that its mouth could be almostly for crown.Except the key point that is different from beer bottle,if you looked carefull,also you could find there are some spots on it neck.It could make your hand much more comfortable when you grabbed the bottle.

Do you know what is annealing and how is annealing proceed ? Actullay, to know more about it, we could follow the aspects of its purpose,equipment and key details.It is a very crucial process that is very important to the quality of glass bottles.Pls see as below:

Purpose:To eliminate harmful residual stress caused by uneven cooling during the molding process, and prevent the bottle from breaking during subsequent processing, filling, transportation or use.Also you could understand by another direction, it is the process of heating a bottle with permanent stress to a temperature at which particles inside the glass can move, and using the displacement of particles to disperse the stress to eliminate or weaken the permanent stress.

Equipment: Annealing furnace (continuous mesh belt annealing furnace)

Heating uniform temperature zone:** Reheat the bottle from the molding temperature (about 500°C) to the annealing point temperature (usually 560°C - 580°C, viscosity about 10¹³ poise).Insulation/stress relief zone: Keep at the annealing temperature for a sufficient time to allow the stress to relax fully.Slow cooling zone: Cool through the strain point temperature (viscosity about 10¹⁴·⁵ poise) at a strictly controlled and very slow rate (such as a few degrees per minute).Fast cooling zone: Cool to room temperature (<70°C) at a faster and safe rate.

Key details: Annealing temperature curve: Accurately set according to glass composition and bottle wall thickness. An unreasonable curve will lead to excessive or uneven residual stress. Temperature uniformity in the furnace:The horizontal and vertical temperature differences need to be strictly controlled. Cooling rate:The slow cooling rate near the strain point is the key to determining the level of residual stress. Hot end coating: Organic tin or titanium compound solution is often sprayed at the entrance of the annealing furnace to form a protective film on the bottle surface to improve scratch resistance and strength.

For this processing, based on above, you could see that hot end coating is belong to it, sometimes, we could say that the hot end coating is processing togther with Annealing. According to our experience, if for large sacle glass factory like us, there is cold end coating. Actually, some of our new customers asked if our glass bottles are scratch proof, for this, as a matter of fact, glass bottle itself is no scratch proof, because the cold painting is no necessary for a glass factory, and many application circumstances is no request for that. However, if it was in the requested circumstances of application, that is necessary. If it was without the processing of cold painting, but it was in the requested circumstances of application, then your bottles would be scratched heavily and spoiled, especially for the bottles that are for the years recycled. But, for us , we can do the cold painting for you, then your bottles would be no any scratch, even for many years.
