1. Adopt advanced energy-saving technology
Save energy, improve melting quality, and extend the life of the kiln. Another use of energy saving is to increase the amount of broken glass. The amount of foreign broken glass is 60% -70%. The most ideal is to use 100% broken glass to achieve the goal of "ecological" glass production.
2. Lightweight bottles
In developed countries such as Europe, America and Japan, lightweight bottles have become the leading products of glass jars.
80% of the glass bottles produced by the German company Obeband are lightweight disposable bottles. Advanced technologies such as precise control of raw material components, precise control of the entire melting process, small mouth pressure blowing technology (NNPB), spray cooling of hot and cold ends of bottles and cans, and on-line inspection are the fundamental guarantees for achieving lightweight bottle and cans. Some countries are developing new bottle and can surface enhancement technologies in an attempt to further reduce bottle and can weight. For example, the German sea leaf company coated a thin layer of organic resin on the surface of the bottle to produce a 1L concentrated juice bottle of only 295 grams, which can prevent the glass bottle from being scratched, thereby increasing the pressure strength of the bottle and can by 20%. Film sleeve labels are also conducive to the weight reduction of glass bottles and cans.
3. Improve labor productivity
The key to improving labor productivity of glass bottle manufacturing is how to increase the speed of glass bottle forming. At present, the generally adopted method in developed countries is to select multiple groups and multiple drip forming machines.
