Problems solved by technology

However, this type of heating body is used in the field of industrial heating, and there are shortcomings such as light radiation attenuation and low heat radiation efficiency; The low radiation efficiency brought by the heat-generating coating on air convection radiation, but due to the weak interface binding force, it is easy to cause the coating to fall off during the working process, especially in the case of rapid heating and rapid cooling.

Embodiment 1-3

[0036] A method for improving the working stability of a heat-generating coating on a glass substrate, the specific steps are as follows:

[0037] Step 1. Select the substrate material as quartz glass with a diameter of 30 mm and a thickness of 2 mm, totaling 3 pieces, and process the quartz glass under the same process conditions. Before treatment, soak in 5% FH solution for 5 minutes, then rinse with clean water, then ultrasonically clean the quartz glass with deionized water for 10 minutes, and finally place the quartz glass in a mixed solution of acetone and absolute ethanol for ultrasonic cleaning 10min, and then blow dry with nitrogen for later use.

[0038] Step 2. Plasma pretreatment:

[0039] Turn on the power supply of the mechanical pump corresponding to the vacuum port 5, turn on the low vacuum gauge, when the indication of the low vacuum gauge is less than 15Pa, open the gate valve, then turn on the power supply of the molecular pump, and when the indication of t...

Embodiment 4

[0044] The procedure is the same as the above example, except that the alternate coating of low-concentration and normal-concentration exothermic coatings on quartz glass is repeated three times. That is, after coating the low-concentration heat-generating coating slurry 12 each time, bake it at a temperature of 250° C. in a nitrogen-containing atmosphere for half an hour, then apply the same thickness of normal-concentration heat-generating coating slurry 13 , and then continue to Baking at 250° C. for half an hour in a nitrogen-containing atmosphere.

[0045] The product of this embodiment can better improve the stability of quartz glass when used as a heat-generating coating material. From figure 2 It can be seen that, using the method of the present invention, after the ion source treats the quartz glass, micropores are formed on the surface of the quartz glass, and then a heating coating is applied. The effect picture after applying the heating coating is as follows ...

Abstract

The invention relates to a method for improving the working stability of a glass substrate heating coating. The invention aims at improving the thermal stability on the basis of ensuring the excellentradiation efficiency of quartz glass. The method is characterized by comprising the following steps: firstly pre-irradiating a quartz glass substrate by using plasma, forming a micropore on the surface of the quartz substrate, coating a heating coating slurry on the surface, baking for half an hour in the nitrogen-containing atmosphere, finally, evenly coating one or more layers of heating coating slurry with the normal concentration, and drying for half an hour. The method enlarges the contact area between the slurry and the substrate, the processed substrate material does not change the macroscopic optical property of the quartz glass; in addition, the thermal radiation efficiency is improved by 30%, the preparation method is simple and reliable and is easy to implement industrially ona large scale.

Description

technical field [0001] The invention belongs to the technical field of heating coating materials for glass substrates, and in particular relates to a method for improving the working stability of heating coatings for glass substrates. Background technique [0002] Quartz glass is an amorphous material with a single component of silicon dioxide, and its microstructure is a simple network composed of silicon dioxide tetrahedral structural units. Due to the large chemical bond energy and compact structure of Si-O, quartz glass has unique properties, especially the optical properties of transparent quartz glass are excellent, and it has excellent transmittance in the continuous wavelength range of ultraviolet to infrared radiation. [0003] The formation of quartz glass is the result of the high temperature viscosity of its melt. Used in the production of semiconductors, electric light sources, semiconductor communication devices, lasers, optical instruments, laboratory instrum...
