Definitions
- This operation consists in eliminating as much as possible gaseous inclusions of various sizes, called “broths”, bubbles or “chips”, the presence of which in the final product is often strictly controlled and sometimes prohibitive.
- gaseous inclusions of various sizes, called “broths”, bubbles or “chips”, the presence of which in the final product is often strictly controlled and sometimes prohibitive.
- the quality requirements in terms of refining are very strict for automotive applications (in particular windshields, which must ensure perfect visibility), and even more stringent for applications of flat glass in the electronic field, in particular as flat screen substrates such as liquid crystal screens (LCD), the presence of gaseous inclusions can then disturb the electrical operation and / or deform certain pixels constituting the image.
- These gas inclusions have several origins. They mainly come from the air trapped between the grains of the pulverulent matter and from degassing due to certain chemical reactions occurring during the glass melting step.
- the molten glass is preferably brought back to a substantially atmospheric pressure by the effect of its own gravity, an effect possibly coupled with an effect of centrifugal force, and then flows out of the mobile device in rotation. towards a forming stage.
- This step of the process is carried out in the lower zone or cavity, preferably cylindrical, located under the vacuum compartment, and at the lower end of which is located the or each glass outlet orifice.
- the rotation plays a role of homogenization until the step of removing the glass from the rotating device. It has in fact been observed that the shear stresses undergone by the glass due to the rotation considerably increase the chemical homogeneity of the glass, this much more effectively than can be done by homogenization by means of mechanical agitators sometimes called “stirrers”. ". In addition, a beneficial effect on the refining is also observed due to these same shear stresses, manifested by a fragmentation of the bubbles still present in a multitude of small invisible or easily absorbable bubbles in the glass. Above 500 revolutions / minute, the feasibility on an industrial scale is however compromised.
