preparation example Construction
[0042] The upper and lower glasses are prepared from flat glass, and the preparation method further includes: preparing the flat glass into a convex glass by using a mold in a bending furnace through the gravity of the glass itself or an external pressure.
[0043] The preparation method further comprises:
[0044] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the convex low-altitude glass to be produced, perform edge grinding, chamfering, cleaning and drying, and use a stencil to print low-temperature glass on the welding surface of the glass Powder preparation edge banding frame;
[0045] In the second step, put the processed two pieces of flat glass into the forming mold, put them into the hot bending furnace, raise the temperature to the softening temperature of the glass, rely on the gravity of the glass itself or the external pressure to make the glass downward to form a convex surface, and then put it into the ...
Embodiment 1
[0134] Embodiment 1: see figure 1 , the low-altitude glass is composed of an upper convex glass 1 and a lower convex glass 2, both of which have edge-sealed frames, and the peripheries of the two glasses are welded together by low-temperature glass solder 3, and the middle is a low-altitude layer. The production method is as follows: First, cut two pieces of flat glass of the required size according to the shape and size of the low-altitude glass to be produced, and perform edge grinding and chamfering. After cleaning and drying, use printing technology to paste low-temperature glass powder on the two pieces of glass. Printed edge banding frame, wherein the upper glass has one edge banding frame, the lower glass has two edge banding frames, the size of the upper glass edge banding frame is between the two edge banding frames of the lower glass, the upper and lower glass After the glass is combined, the edge sealing strip frame of the upper glass can be fitted between the two e...
Embodiment 2
[0137] Example 2: see figure 1 , the two pieces of glass are tempered glass or semi-tempered glass, one of which is still low-emissivity glass, and there are edge-sealed frames on the two pieces of glass. The production method is as follows: First, cut the required size according to the shape and size of the low-altitude glass to be produced. A piece of flat glass and a piece of low-emissivity glass are edged, chamfered, cleaned and dried, and the low-temperature glass powder paste is printed on the two pieces of glass by screen printing technology to form an edge band frame. The upper glass has a There are two edge-seal frames and lower glass edge-seal frames, the size of the upper glass edge-seal frame is between the two edge-seal frames of the lower glass, after the upper and lower glass are combined, the edge seal frame of the upper glass can Fitted between the two edge-sealed frames of the lower glass; secondly, put the two pieces of glass into the mold, place them in a h...
