Embodiment 1
[0028] A vacuum glass degassing method, its specific steps comprising:
[0029] Step 1: Introduce a set liquid into the vacuum chamber of the vacuum glass, and keep the set liquid in the vacuum chamber for a set time; the set liquid is hydrogen peroxide, periodic acid or dichromic acid, etc. liquid.
[0030] Step 2, heating the vacuum glass to the set temperature, so that the residue in the vacuum chamber reacts with the set liquid and then decomposes and oxidizes;
[0031] Step 3, extracting the residual liquid after the reaction in the vacuum chamber;
[0032] Repeat steps 1 to 3 until the residue in the vacuum chamber is fully decomposed and oxidized.
[0033] Step 4, evacuate the vacuum chamber of the vacuum glass until the vacuum chamber reaches the set pressure.
Embodiment 2
[0035] Such as figure 1 As shown, a vacuum glass degassing device using the above degassing method, which includes a glass plate carrier 12, a liquid storage device 7, a first liquid pump 14, a second liquid pump 13, a heating device 11, and a suction cap 2a , suction cap compression device 4 and vacuum pumping system 8; vacuum glass 1 is placed on the glass plate carrier device 12; liquid storage device 7 passes through liquid pipeline, first liquid pump 14, four-way valve 5, suction cap 2a is connected with the suction port 2 of the vacuum glass; the second liquid pump 13 is connected with the four-way valve 5 and the suction cap 2a with the suction port 2 of the vacuum glass through the pipeline; the vacuum pumping system 8 is connected through the pipeline, the four-way The valve 5 and the suction cap 2a are connected with the vacuum glass suction port 2; The suction cap pressing device can be an electric stretch rod, a hydraulic cylinder or an air cylinder, etc.
