The effect of surface tension on glass bottle products to eliminate streaks
In the melt of glass bottle products, when the surface tension between different parts is different, there will be deformable material transfer, that is, the effect of surface tension, which can eliminate streaks and nodules. The experimental results show that glass with higher surface tension often forms fringe centers in glass with lower surface tension, and maintains its dense morphology，glasscookware.
Therefore, the contrast of surface tension is very important when the glass that is entangled with each other in stripes melts with each other. Glass bottle products that are highly wettable (low surface tension) exhibit substantial mass transfer. The speed at which this glass bottle product spreads around it, that is, its speed per unit time. The increase of the "action radius" increases with the decrease of surface tension and viscosity. Compared with the diffusion speed, this speed is much larger. The repetition of this process plays a decisive role in promoting the homogenization of the melt.
During the melting process of glass bottle products, two adjacent parts on the liquid surface that are in contact with the gas phase at the same time often have such a situation that their surface tension is just opposite to its density, and the surface tension is small and the density is high. Parts always fall into and dissolve in parts with high surface tension and low density.
The result is that the fringes are always contained within the portion with higher surface tension. If the melting is not uniform, the glass body is locally rich in SiO2, or the material containing high A12 O3 is dissolved from the refractory material, which will result in lower density and higher surface tension.
The same is true for the evaporation of Na20 from the melt surface. From this, it can be fully understood that the portion containing Sioz and A12 03 high will cause streaks. In addition, the effect of the kiln gas on the degree of oxidation of the sulfur in the glass will lead to similar results. Sulfur in the form of 803 will strongly reduce the surface tension of the glass, so the glass containing 803 will disperse, while the glass containing S2 will be encapsulated.
