preparation example Construction
[0038] The upper and lower glasses are prepared from flat glass, and the preparation method further includes: preparing the flat glass into convex toughened glass by using a mold in a bending furnace through the gravity of the glass itself or the external pressure.
[0039] The preparation method further comprises:
[0040] The first step is to cut two pieces of flat glass of the required size according to the shape and size of the convex tempered vacuum glass to be produced, and perform edge grinding, chamfering, cleaning and drying;
[0041] 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 furnace. When the temperature is lowered to room temperature, the upper and lower glasses in the shape of co...
Embodiment 1
[0133] Embodiment 1: 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 vacuum glass to be produced. A piece of flat glass and a piece of low-emissivity glass, after grinding, chamfering, cleaning and drying, use printing technology to print low-temperature glass powder paste on the two pieces of glass to form an edge banding frame, and the upper glass has an edge banding The frame and the lower glass have two edge-seal frames, and 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 be fitted Between the two edge-sealed frames of the lower glass; secondly, put the two pieces of glass into the mold, place t...

A piece of flat glass and a piece of low-emissivity glass, after grinding, chamfering, cleaning and drying, use printing technology to print low-temperature glass powder paste on the two pieces of glass to form an edge banding frame, and the upper glass has an edge banding The frame and the lower glass have two edge-seal frames, and 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 be fitted Between the two edge banding frames of the lower glass; secondly, put the two pieces of glass into the forming mold, w...
