Description
Technical Field
The invention relates to a glass welding method.
Background
Vacuum glass formed by compounding a plurality of glass plates is also a subject of competitive research because of its outstanding sound-insulating, heat-insulating and heat-preserving properties.
In the past, vacuum glass has been made by sealing the edges of glass sheets with various plastic or resin materials. For example, there are patent documents that use organic glass such as PC, ABS, LDPE, PVC, etc. as the sealing material, and there are patent documents that use materials of laminated glass such as PVB, EVA (EN), etc. in which the above materials are placed between two glass plates and then made into a preform together with the glass plates, and then the preform is pressed under appropriate conditions to seal the edges of the glass plates. The process is similar to the process for manufacturing laminated glass, although composite sealing between glass plates can be realized, the gas permeability and the moisture permeability of most plastic and resin materials are far greater than those of glass, moreover, most organic materials are only physically bonded with the surfaces of the glass plates, the bonding parts are difficult to prevent leakage, and once gas (including water vapor) permeates, the sealing strength is directly weakened, condensation in the interlayer and glass mildew are caused. In addition, the aging problem of the organic material also directly affects the service life of the vacuum glass with the passage of time. Therefore, the above method has gradually faded out the production of vacuum glass.
Later, the invention uses low-melting-point glass frit as a sealing material to manufacture vacuum glass, namely: firstly, the low-melting-point glass frit is placed at the position where the edges of two adjacent glass plates are to be sealed, and then the low-melting-point glass frit is melted by flame or electric heat to hermetically connect the edges of the two glass plates. Because the low-melting-point glass material adopted by the process is usually a lead-zinc (PbO-ZnO) glass material, lead metal in the low-melting-point glass material can harm the environment and the human health, and therefore, the low-melting-point glass material has the risk of environmental protection after being used for a long time; in addition, the heating temperature in the sealing process is generally about 400-500 ℃, the glass plate sealed by the process can generate edge thermal stress, and proper annealing treatment is needed, so that the production efficiency is greatly reduced, and the processing cost is increased.
At present, in glass ultrasonic welding, the temperature of a whole glass plate is maintained to be more than 160 ℃, but the glass is deformed and uneven, particularly, the deformation of a rectangular glass plate is more obvious, the glass welding quality is influenced, and the welding speed is slow.
In order to solve the problem of glass deformation, after the glass plate is locally heated by hot air, the local temperature before welding reaches over 160 ℃, the glass is flat and does not deform, and the ultrasonic welding of the glass can be realized. But the welding speed is not ideal, and the welding speed is improved while the welding quality is ensured by increasing the temperature of the ultrasonic welding iron head.
