Problems solved by technology
In this process, the quality requirements for the flatness and thickness of the glass surface are very strict. The strengthened glass needs to be cut, ground, and polished before it can be strengthened. This process requires sophisticated measuring instruments, and the sample preparation and testing operations same cumbersome
The final test cycle is long and the cost is high

Embodiment Construction
[0017] Referring to the accompanying drawings, a method for testing the depth of glass chemical strengthening treatment is especially suitable for glass that can be strengthened. This method is based on the test of homogeneous glass filaments, and specifically includes the following steps:
[0018] A. Melt the homogeneous glass substrate sample and make glass filament according to the glass filament processing technology, measure and record the diameter range of the glass filament;
[0019] The specific steps of making glass wool are:
[0020] ① Ignite the mixed gas of natural gas and oxygen, control the flame by adjusting the flow of natural gas and oxygen, first reduce the flame, and preheat the glass sample with tweezers, so as to prevent the glass sample from being overheated due to the high temperature inside and outside the glass. Uneven, cracking occurs;
[0021] ② After the glass sample is preheated, increase the flame, burn one end of the glass, and preheat the drawi...

Abstract
A method for testing the depth of glass chemical strengthening treatment, which is suitable for glass that can be strengthened. The method is based on the test of homogeneous glass filaments, and includes the following steps: melting a homogeneous glass substrate sample, and making glass filaments according to the glass filament processing technology, Measure and record the diameter range of the glass filament; soak the glass filament in 380-450°C, 99.9% potassium nitrate solution for 4-10 hours, then take it out, cool naturally, wash, and dry; cut the above glass filament into segments, at least one end After grinding and polishing, the sample to be tested is formed; with the help of a high-power microscope and a full-wave plate set between the high-power microscope and the sample to be tested, the position of the interference area in the glass filament is observed and photographed, and the strengthening depth of the glass filament is measured and recorded with the aid of a microscope ruler; repeat Complete the determination of each sample and record it, and calculate the arithmetic mean value of all structure depths to determine the strengthening depth. The method of the invention can make the detection of glass chemical strengthening depth simple and fast, and the test data is accurate.
Description
technical field [0001] The invention belongs to the field of glass physical and chemical performance testing, and relates to a method for testing the depth of glass surface strengthening treatment, in particular to a method for testing the depth of surface strengthening after a glass fiber model is chemically strengthened. Background technique [0002] With the development of science and technology, the application range of cover glass in touch screen has become more and more extensive, from the operating system of factory equipment for industrial use, electronic query facility for public information query to mobile phone, PDA, digital camera, etc. of consumer electronics All can see the touch screen. During the use of touch screen products, it is inevitable to contact, rub, scratch, and touch other objects. As a result, the surface of the display screen is rough and the smoothness is reduced, which affects the use effect and is more likely to cause the screen to break and b...
