Processing method of K9 ultrathin glass

Abstract

The invention relates to the technical field of optical glass processing, in particular to a processing method of K9 ultrathin glass, which comprises the following steps: cutting a thick and heavy K9glass brick raw material to obtain a K9 glass sheet as a semi-finished product for later use; then, subjecting the obtained K9 glass sheet to polishing and thinning for multiple times to obtain K9 ultrathin glass, wherein the process specifically comprises the steps of physical thinning, attaching and fixing, chemical thinning, cleaning, mechanical thinning and peptizing; cutting and inspecting afinished product; and finally, packaging and storing the finally obtained product. The advantages of physical thinning, chemical thinning and mechanical thinning are brought into full play, the thinning speed is high, the thinning thickness is controllable, and the K9 ultrathin glass with the ideal thickness and the flat and smooth surface is obtained; and by the adoption of a top-spraying waterfall flow type chemical thinning method, an etching solution can be recycled, energy and cost are saved, the automation degree of industrial production is improved, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of optical glass processing, in particular to a processing method of K9 ultra-thin glass. Background technique [0002] In the past 20 to 30 years, the optical industry has developed rapidly and has become the focus of emerging industries in the world. The design and manufacture of optical components and the like have undergone tremendous changes along with the development of optical technology. With the continuous development of the field of optical glass, the demand for optical glass is also increasing. [0003] K9 optical glass has unparalleled advantages in the optical field due to its excellent optical properties, and is a typical optical material. It has much higher characteristics than ordinary glass, and is mostly used in filters, telescopes, etc. In the existing market, K9 glass is often used in the processing of various accessories because of its permeability similar to crystal , After cutting a...

Problems solved by technology

[0005] At present, the thinning technology of glass mainly includes physical thinning technology and chemical thinning technology. Among them, the surface of physical thinning and grinding is flat and smooth, and the thickness can be precisely controlled. It does not require special chemical treatment, but generally takes a long time. , and is only suitable for the thinning of small-sized glass, which is not conducive to mass production and hinders its development; while the chemical thinning speed is faster, the surface is more uniform, and the thinning speed can be controlled by adjusting the acidity of the etching solution and time And thickness, very suitable for industrial production, but the surface of chemical etching is difficult to control, which is also a major problem that limits its application
