Embodiment 1

[0024] A process for changing the ultimate pressure of flat glass after coating, comprising the following steps:

[0025] 1) Process toughened layer: coat a layer of toughened layer on flat glass;

[0026] 2) Soft material layer processing: process a layer of material with relatively soft chemical properties on the tempered layer;

[0027] 3) Processing anti-reflection film system: the film system is processed on the soft material layer by means of ion source assisted coating;

[0028] 4) Plating waterproof material: After the film system is processed, a layer of waterproof material with a thickness of 12~25nm is plated.

[0029] The vitreous body structure obtained by adopting this process is composed of a waterproof material layer, a film system layer, a soft material layer, a toughened layer and a flat glass layer from the outside to the inside.

[0030] Further, in order to better realize the present invention, the following setting method is adopted in particular: In th...

Embodiment 2

[0037] A process for changing the ultimate pressure of flat glass after coating, comprising the following steps:

[0038] 1. The flat glass is coated with a tempered layer first.

[0039] 2. Process a material with relatively soft chemical properties (BP500, Ti 3 o 5 , SiO 2 Any one of them), changing the tension of the entire glass structure, but will not cause the transmittance of the glass structure to change and do not use ion source (RF source) assistance in the process of processing, and compare the chemical properties on the tempered layer When processing soft materials, the electron gun should be set according to the following parameters: BP500: 8mA, Ti 3 o 5 : 360~300mA, SiO2 2 : 6mA.

[0040] 3. After processing the material layer with relatively soft chemical properties, the film system is processed according to the transmission or emission requirements of the entire glass structure. When processing the film system, an ion source (RF source) is used to assist ...

Abstract

The invention discloses a process for changing the ultimate pressure borne by plane glass after film coating. The process comprises the following steps: 1) processing a tempered layer: coating the plane glass with the tempered layer; 2) processing a soft material layer: processing a layer of material with relatively soft chemical property on the tempered layer; the film system is processed on the soft material layer in an ion source auxiliary coating mode, and the waterproof material is plated after the film system is processed, so that the ultimate pressure borne by the lens can be effectively changed, the pressure after original coating processing is increased to 25-35 Kg from 8-12 Kg, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of plane glass processing, in particular to a process for changing the coating film of the plane glass to bear the ultimate pressure. Background technique [0002] Flat glass processing is now used in all walks of life, in military affairs and in all aspects of life. At present, the lens processing environment is that the ultimate pressure of the glass after coating processing is basically 8~12Kg, so the quality of the product will be easy to appear when it is used. broken features. Contents of the invention [0003] The purpose of the present invention is to design a process for changing the ultimate pressure of flat glass after coating, which can effectively change the ultimate pressure of the lens, from 8~12Kg after the original coating process to 25~35Kg, and improve the quality of the product. [0004] The present invention is achieved through the following technical solutions: a process for changing...
