Glass packaging industry to compete with paper product containers and plastic bottles and other new packaging materials and containers, glass bottle production enterprises in developed countries has been committed to product quality and more reliable, more beautiful appearance, lower cost, the price cheaper.
In order to achieve these objectives, the development trends of foreign glass packaging industry is mainly manifested in the following aspects:
Improve labor productivity
The key to improve the glass bottle manufacturing labor productivity is how to improve the forming speed of glass bottle. Molding machine is now generally take the developed countries way is to use multi group, drip feed. Large kiln, and high-speed molding machine, ability must have a large number of stable supply of high quality glass liquid, drop the temperature and viscosity of the best molding conditions to meet the requirements of.
Adopting advanced energy-saving technology
To save energy, improve melt quality, prolong the furnace to make another way of energy saving is to increase the amount of broken glass, broken glass foreign the added amount of 60% - 70%. The ideal is to use 100% of the broken glass, to achieve "ecological" glass production target.
Improve the production concentration
In order to adapt to the glass packaging industry is facing a new challenge other packaging products caused by severe competition situation, a lot of glass packaging production enterprises began to carry out mergers and reorganization, improve concentration of glass container industry, to optimize the allocation of resources, improve economies of scale, reduce the disorderly competition, enhance the development ability, it has become the current world trend of the glass packaging industry.
Germany Obedand company production of glass bottles, 80% is the disposable bottle lightweighting. The precise control of composition of raw material, melting the whole process of precision control, small mouth blowing pressure technology (NNPB), the advanced technology of bottle cold end spraying, online detection, is the fundamental guarantee for the realization of lightweight containers. Some countries are developing new and surface enhanced technology, trying to further reduce the bottle weight.
Therefore, the composition of raw material must be very stable, the developed countries of the glass bottle production enterprises with the standard raw material refining are provided by the raw material production enterprises special. Ensure furnace thermal parameters of melting quality to use digital control system, realize the whole process of optimal control. |
