A u-shaped groove platinum-rhodium alloy bushing plate

Abstract

The invention discloses a U-shaped groove platinum-rhodium alloy leakage plate, which belongs to the technical field of flexible glass forming equipment. The platinum-rhodium alloy leakage plate includes a tank body, and the bottom plate of the tank body is provided with slits for passing glass liquid. The length direction is the same as the length direction of the tank body. The key point is that the slits are divided into sequentially connected first width gradient slits, middle equal width slits, and second width gradient slits from one end to the other end along the length direction. The widths of the width gradient slit and the second width gradient slit gradually decrease from one end close to the middle equal width slit to the other end. The slit with a wide middle and narrow ends can effectively reduce the thickness of the edge of the glass ribbon, increase the effective width ratio of the glass, and make the appearance of the glass plate more even.

Description

technical field [0001] The invention belongs to the technical field of flexible glass forming equipment, and relates to a bushing, in particular to a U-shaped groove platinum-rhodium alloy bushing. Background technique [0002] Flexible glass refers to ultra-thin glass with a thickness of ≤0.1mm that can realize the "roll-to-roll" process. Flexible glass can be bent while having glass's hardness, transparency, heat resistance, electrical insulation, air impermeability, and stable mechanical and chemical properties in oxidative and light environments. The high temperature resistance of flexible glass can meet the requirements of high temperature treatment for some optoelectronic devices. Its outstanding bending performance and winding performance make it possible to use continuous "roll-to-roll" printing technology to prepare various optoelectronic devices. It is the future flexible glass. The preferred substrate for printing optoelectronic devices may lead to essential chan...

Problems solved by technology

The secondary drawing method is to reheat the original glass sheet and stretch it through the traction roller. The secondary drawing method can draw flexible glass below 0.1mm, but due to the limitation of the process, it cannot be produced continuously, and it is difficult to realize industrialization.

[0005] During the slit pull-down method experiment, it was found that the structural design of the platinum-rhodium alloy bushing plate was unreasonable, which would lead to a low proportion of the effective width of the glass
