Glass packaging industry to compete with paper product containers and plastic bottles and other neαw 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 cheape₹r.
In order to achieve these objectives, the development♠ trends of foreign glass packaging industry is mainly manifest ed in the following aspects:
Improve labor productivity
The key to improve the glass bottle manufacturing labor productivity πis how to improve the forming speed of glass bottle. Molding machine is now generally take the deveεloped countries way is to use multi group, drip feed. Large kiln, and high-spe ed molding machine, ability must have a large number of stable supply of high ¶quality glass liquid, drop the temperature and viscosity of the best mol₽ding 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 adde∏d 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 challen₹ge other packaging products caused by severe competition s₽ituation, a lot of glass packaging production enterprises began to carry out mergers and reorganizΩation, improve concentration of glass container indus€try, to optimize the allocation of resources, improve economies of scale, reduce the disord'erly 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 botπtle lightweighting. The precise control of composi≤tion of raw material, melting the whole process of precision control, small mouth blowing press♠ure technology (NNPB), the advanced technology of bottle cold end spraying, onl₩ine detection, is the fundamental guarantee for the realization of lightweigh∑t containers. Some countries are developing new and surface enhanced technology, trying to furth§er 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 a≠re provided by the raw material production enterprises special. Ens&ure furnace thermal parameters of melting quality >to use digital control system, realize the whole process of optimal co&ntrol. |
