Embodiment 1
[0053] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.
[0054] (2) Use a mechanical drill or a laser drilling machine to make a vent hole with a diameter of 2mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.
[0055] (3) Make isolation support points on the rear substrate glass by screen printing. Use amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a coefficient of thermal expansion slightly smaller than that of the glass panel and an organic solution to prepare a rheological slurry suitable for screen printing. Then use the screen printing method to print wet film dots with a diameter of about 0.5mm and a thi...
Embodiment 2
[0063] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.
[0064] (2) Use a mechanical drill or a laser drilling machine to make a vent hole with a diameter of 1mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.
[0065] (3) Make isolation support points on the rear substrate glass by screen printing. A slurry with rheological properties suitable for screen printing is prepared by using amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than that of the glass panel and an organic solution. Then use the screen printing method to print wet film dots with a diameter of ab...
Embodiment 3
[0073] (1) Cut, edge and clean the original glass plate according to the required size. The original glass plate can be ordinary float glass, tempered glass, various coated glass, self-cleaning glass, low-emissivity glass, high visible light transmittance glass and so on.
[0074] (2) Use a mechanical drill or a laser drilling machine to make an exhaust hole with a diameter of 3mm on a glass plate. This piece of glass is called the front substrate glass. Correspondingly, the other piece of glass is called the rear substrate glass.
[0075] (3) Make isolation support points on the rear substrate glass by screen printing. A slurry with rheological properties suitable for screen printing is prepared by using amorphous low-melting glass powder (hereinafter referred to as low-melting glass powder A) with a thermal expansion coefficient slightly smaller than that of the glass panel and an organic solution. Then use the screen printing method to print wet film dots with a diameter o...
