The origin of the "two hybrid theory": In the early 1950s, an international conference on the glass industry was held. At that meeting, an engineer put forward the famous argument of "two mixers". That is to say, in the manufacturing process of the glass, two times of mixing is carried out. First, the solid mixture of the powder in the compounding process accounts for 70% of the importance; the second is that the liquid mixture in the melting process is 30% important. Because the glass liquid at high temperature is still very viscous, it is not as easy to homogenize as people think; while the powder at normal temperature is easier to mix evenly. The arguments of the two mixers have inspired endless memories of glass manufacturers and engineers... At that time, the mechanical and electronic technology had already reached a high level. Therefore, after the 1950s, the electromechanical compounding production line came into being, and it was quickly promoted in various countries.
This international conference is an important meeting to promote the rapid development of the world glass industry, and it is also a big leap in people's understanding of glass manufacturing technology. It has a milestone in the history of international glass manufacturing.
(2) Glass manufacturing begins with awareness and philosophy, finally quality and environmental protection
It is very important for people to have sufficient understanding and good ideas before starting to the goal. The backwardness of products and technologies stems from the backwardness of understanding and ideas;
From the current point of view, most glass companies have not paid enough attention to the control of raw material composition, particle size and moisture, and are still subject to the constraints of raw material suppliers, which is one of the bottlenecks for manufacturing high quality glass products;
At the same time, it does not pay attention to the technical research of process links and details and takes measures. The design and manufacture of glass kiln still stays in the stage of individual heroism. Various "four new technologies" have not been fully applied, such as kiln structure optimization design and materials. Application, thermal insulation, bubbling, electric fluxing, endoscopic monitoring, emission treatment, waste heat utilization, automation control, etc. At present, there is no perfect modern large-scale glass kiln model for learning and reference, and it is also manufacturing high-quality glass. One of the bottlenecks is very weak, and national standards, industry standards, corporate standards and norms are still behind the times. The standard of technological progress must be preceded, and the backwardness of standards is the bottleneck that hinders development.
Enterprises and their products are ultimately tested by market quality and social environment.
(3) 10 classic requirements for mixing solids
Particle size of glass raw materials: 60% to 80%, >85%, especially mineral raw materials;
Composition of glass raw materials: stable, especially the control of feldspar and silica sand minerals;
Water content of glass raw materials: <8~10%, the focus is on silica sand and feldspar;
Weighing accuracy of glass raw materials: 1% to 1/3000
Feeding sequence: silica sand + soda ash + feldspar + auxiliary materials and small materials mixing time: 3 ~ 5 minutes mixing uniformity: ≥ 96 ~ 98%
Mixture moisture content: 5 to 7%
Broken glass: particle size ≤ 50mm, after mixing or conveyor belt to join blanking distance: ≤ 1 meter drop above 10 items is a classic quality requirement, the enterprise should achieve standardized control.
According to the "two mixers" theory, uniform glass is produced, and the cold solid mixing work should account for 70%, and it is easier to do well. The key is to know.
