Description
Technical field
The present invention relates to sheet glass plated film field, particularly a kind of sheet glass float glass process filming equipment.
Background technology
Online chemical vapour deposition plated film, comprise online LOW-E glass, online TCO glass, self-cleaning film, reflectance coating, solar control film etc., in sheet glass production process, in molten tin bath or annealing section, the elementary gas of film will be formed, or a kind of, several compound is through vaporizer gasification, by reactor, is evenly sprayed onto glass surface, gas and glass surface generation chemical reaction, generate transparent fine and close solid metal compound film at glass surface and form.
Current, sheet glass 90% is produced by floating process.Float glass is that the glass metal after fusing enters molten tin bath through runner, floats in the tin liquor of fusing, and because of self gravitation and glass metal effect of surface tension, self-assembling formation glass ribbon, and be subject to force-extension and regional temperature control is made;
It is large that floatation glass production line has output, and operation is many, produces continuously, high temperature, the feature such as process procedure is many, controlling unit complexity, on sheet glass float line, carry out the new product development of chemical vapour deposition plated film, not only can affect normal production, also can cause huge waste;
The simulation float glass coating wire being formed by glass tempering furnace transformation, sheet glass is by ceramic rod transmission, or by crawler-tread, heating zone was heated to after design temperature for some time, send into plated film section and carry out chemical vapour deposition, then, send into annealing section and carry out anneal; The defect of this equipment is, can not simulate really floatation glass production line, and glass has been that a slice is carried out lower a slice operation later again, can not form continuous glass ribbon; Because glass size is little, speed is fast, time is short and pressing at process plated film reactor air-flow spout for sheet glass, and the plated film gas that sprays to glass does not also form steady air flow, and sheet glass has just passed through plated film device, can not form the stable air-flow of vapour deposition, easily cause plated film inhomogeneous, and plated film air-flow very easily enters the reverse side of sheet glass, make reverse side form rete, affect performance index, affect outward appearance.Plated film device is placed in plated film intersegmental part, affected by high temperature deformation, and it is consistent that the distance between plated film device spout everywhere and sheet glass is difficult to reach, and also easily causes plated film inhomogeneous, high to the material requirements of plated film device, and design, processing, installation difficulty are large; Plated film section is unlimited open architecture, and atmosphere communicates, and cannot simulate protectiveness N2, H2 atmosphere in molten tin bath, and some plated film gas is inflammable and explosive, and plated film section is high temperature, is again open architecture, easily causes the safety problems such as combustion explosion.Through extensively retrieval, not yet find comparatively desirable technical scheme.
