Examples
In this embodiment, a method for rapidly testing the sealing performance of a TFT glass sealant is provided, so as to visually evaluate the sealing performance of the sealant in TFT glass, and further compare the sealing performance of different TFT glass products.
As shown in fig. 1, a flow chart of a method for rapidly testing the lifetime of a TFT glass sealant according to the present application is shown, and the method for testing the present application will be described in detail with reference to fig. 1 below:
a rapid test method for the sealing performance of TFT glass sealant comprises the following steps:
s10: pouring the prepared colored solution into a container 1, taking TFT glass, soaking the TFT glass in the colored solution, placing the container 1 into a vacuum box, and vacuumizing to remove the air pressure value X1MPa. Preferably, to ensure experimental accuracy, the TFT glass needs to be completely immersed in the colored solution. Further, in order to simulate the state of glass at atmospheric pressure, the colored solution is completely exposed to the container 1.
In this embodiment, the absolute value of the air pressure value X1 or X2 in the vacuum pumping box is preferably controlled to be 0-0.1 MPa. In some preferred embodiments, the absolute value of the air pressure value X1 or X2 is 0.090-0.098 MPa, further, when the product to be tested is put in, for the accuracy of the experiment, it is required to check that the performance and appearance of the sample are not problematic, that is, to check the tightness of the product to be tested, and to see whether the appearance of the product to be tested is damaged.
S20: and continuously soaking the TFT glass in the colored solution, taking out the TFT glass after 72 hours, cleaning the colored solution by using a cleaning solution, and observing whether the colored solution enters the TFT glass.
Preferably, at least 10 TFT glasses can be simultaneously accommodated in the container 1 containing the colored solution at each test. It is further preferred that, as shown in fig. 2, in order to realize simultaneous detection of 10 TFT glasses, snap points 11 are symmetrically provided on opposite sides of the container 1 for resting the TFT glasses. It will be appreciated by those skilled in the art that the shape of the snap-on point 11 may be designed as a circle, rectangle or square, TFT glass may be placed on the snap-on point 11, placed in the container 1, placed layer by layer in the container 1, the colored solution fully submerges the product under test, exposed in the container 1, i.e., the container 1 is not provided with a cover plate, the solution is exposed, and then the container 1 with the TFT glass placed thereon is placed in a vacuum drying oven, evacuated, and tested in a simulated atmospheric environment. In this embodiment, 10 pieces of glass to be tested are put into the test device at a time. In some preferred embodiments, more than 10 glass to be tested may be placed at a time, or of course, less than 10 glass to be tested may be placed at a time, where the number of samples to be tested placed will not affect the test results, and therefore, there is no excessive restriction.
Preferably, when observing whether a colored solution is entered into the TFT glass, it is also necessary to confirm whether bubbles are entered into the TFT glass. If there is a bubble, this will affect the observation. Therefore, in the observation, on one hand, whether red ink enters or not is observed, and whether air bubbles enter or not is also observed, and the air bubbles enter to also indicate that the sealing property of the TFT glass sealant is affected. Furthermore, the colored solution can be red ink, the cleaning liquid can be acetone solution, and the acetone solution can well clean the colored solution, so that the observation result is prevented from being wrong.
S30: if no colored solution is observed to enter, continuously soaking, and increasing the air pressure value pumped by vacuum pumping; until the colored solution enters the TFT glass, the test is finished, the TFT glass sealant is failed, the pumped-off air pressure value X2MPa when the sealant is failed is recorded, and the person skilled in the art can understand that the larger the X2 value is, the better the sealing performance of the TFT glass sealant is represented.
By comparing at least 10 test samples, recorded X1 or X2, the sealant properties of the comparative TFT glass can be visually assessed using the present method. Wherein one standard atmospheric pressure=0.1 MPa. The minimum extracted air pressure value is 0 and the maximum air pressure value is 0.1MPa, namely, the atmospheric pressure is completely extracted in the limit state.
After the test was completed, the sealing results of 10 TFT glass samples at atmospheric pressure were shown in the following table:
remarks: the remaining value is the remaining air pressure value, and the more the air pressure is extracted, the smaller the remaining air pressure value is; the smaller the residual value, the better the representative performance; 0.1 =1x10_1; 0.01 =1x10 -2 ；0.001＝1x10 -3 ；0.0023＝2.3x10 -3 ；0.00023＝2.3x10 -4 ；1x10 -4 ＝0.0001；3.2x10 -4 ＝0.00032；0.0001<0.00032；
By comparing experimental data, 0.0001, i.e. 1x10, is good -4 The TFT glass has good sealing performance.
From the above examples, a comparison of the sealing properties of 10 samples can be visually compared. According to the method, the sealing property of the TFT glass is represented by the atmospheric pressure resistance value of the TFT glass sealant, the sealing property of the TFT glass can be rapidly detected by the method, and further the sealing property of the sealant between different samples can be rapidly evaluated and compared, so that the sealing property of the TFT glass can be intuitively evaluated in the early stage of a project, and the problem that a test product is likely to be applied in an extreme environment can be conveniently tested. Here, it should be noted that, in the embodiment, the TFT glass 1, the TFT glass 2, and the TFT glass 3 to be tested are different types of glasses, and are used for different projects, so that the service lives of the TFT glass 1, the TFT glass 2, and the TFT glass 3 are greatly different.
