Description
Technical field
The utility model belongs to TFT-LCD glass production field, relates to a kind of platinum channel.
Technical background
The Main Function of platinum channel in the TFT-LCD production process is clarification, homogenizing, cooled glass liquid, and the glass metal of qualified high-quality is provided to next procedure.
Platinum channel plays very important effect in the production process of base plate glass, but the platinum channel cost is high, cost is expensive, and thermopair is fragile when building by laying bricks or stones causes building by laying bricks or stones expense and improve, in use, and the platinum channel cracky; It will be for moulding provides the glass metal of stablizing high-quality, so in case damage and will cause an immeasurable loss.Platinum channel easily brings platinum volatilization and the problem of the glass defect that produces-platinum particle.Existing platinum channel MaLS is only 18 months, and the life-span is shorter.
The utility model content
The purpose of this utility model is to provide a kind of platinum channel, to solve platinum channel cracky, the problem that the life-span is shorter.
For achieving the above object, the utility model adopts following technical scheme:
A kind of platinum channel comprises platinum channel body and the structure brick layer that the platinum channel body is wrapped up, and is filled with Al between described platinum channel body and structure brick layer
2O
3Powder.
The utility model further improves and is, described structure brick layer is provided with through hole, is inserted with the thermopair of measuring the platinum channel body temperature in through hole.
The utility model further improves and is, the quantity of thermopair is at least 2.
The utility model further improves and is, described structure brick layer ecto-entad is followed successively by high alumina insulating brick-layer, alumina bubble brick layer and α-aluminum oxide brick layer.
With respect to prior art, the beneficial effects of the utility model are:
By the structure brick layer to platinum channel body parcel is set, and fill Al between structure brick layer and platinum channel body
2O
3Powder has extended 6-9 months work-ing life of platinum channel, has guaranteed the safety in production when platinum channel is produced glass metal.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein 1 is α-aluminum oxide brick layer, and 2 is the alumina bubble brick layer, and 3 is the high alumina insulating brick-layer, and 4 is the platinum channel body, and 5 is through hole, and 6 is Al
2O
3Powder.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of platinum channel comprises platinum channel body 4 and the structure brick layer that platinum channel body 4 is wrapped up, and is filled with Al between platinum channel body 4 and structure brick layer
2O
3Powder; Structure brick layer is provided with through hole 5, is inserted with the thermopair of measuring platinum channel body 4 temperature in through hole; The quantity of thermopair is at least 2; Structure brick layer ecto-entad is followed successively by high alumina insulating brick-layer 3, alumina bubble brick layer 2 and α-aluminum oxide brick layer 1.
Wherein in platinum channel body 4, the zirconium white disperse is formed the dispersion oxidation zirconium in the platinum molecule.
The building method of the utility model platinum channel comprises the following steps:
1) processing of platinum channel body surface
Look for the space of a cleaning in treating processes, on-the-spot staff wears clean garment, hair is taken in clean garment, with clean non-dust cloth, wiping is carried out on the platinum channel surface, until the surperficial foreign of platinum channel body 4 and visibility dust, with industrial alcohol, the platinum channel body surface is carried out wiping again, with the wide pure aluminium silicate silk ribbon of 10-20mm, platinum channel body 4 surfaces is comprehensively swathed after wiping is completed, guarantee that platinum channel body 1 is not exposed to outside.
2) make structure brick layer
Make the structure brick layer of parcel platinum channel body 4, structure brick layer is followed successively by high alumina insulating brick-layer 3, alumina bubble brick layer 2 and α-aluminum oxide brick layer 1 from outside to inside.
3) build by laying bricks or stones
At first all thermopairs are carried out combing, must hold the thermopair root and carry out combing in carding process, then the import porcelain tube that thermocouple wire is worn diameter 3mm is entered, galvanic couple silk head exposes at least that the standby connection line of 30mm uses, and thermopair is carried out label confirm, and mark.After the thermopair combing is complete, thermopair is extended exhibition directly, recycle silicon acid aluminum casing all carries out thermopair coated.Finishing heat galvanic couple after coated completing is the through hole of thermopair level by structure brick layer.In this process galvanic couple can not bend, distortion, reserve expansion space to galvanic couple.
Then, platinum channel body 4 is put into structure brick layer, and platinum channel body 4 positions are corrected, use at last Al
2O
3Powder 6 perfusions.Guarantee in filling process evenly, in order to avoid cause passage in use to cause product quality problem owing to cramming inhomogeneous this 4 inequality of being heated of platinum channel that causes.Build by laying bricks or stones and platinum channel is comprehensively checked after completing, and connect its auxiliary facility, platinum channel enters to be produced the temperature rise period.The material that the characteristics that in platinum channel bottom construction brick layer, insulating brick is higher according to distance platinum channel body 4 nearlyer temperature adopt is different, the insulating brick of bottommost is the high alumina insulating brick, being alumina bubble brick above the high alumina insulating brick, is the α-aluminum oxide brick above alumina bubble brick.In the passage temperature-rise period, note the thermopair changing conditions.
Platinum channel of the present utility model provides qualified glass metal to play considerable effect to tank furnace process optimization, stable and downward operation.
It is short the work-ing life under hot environment that the utility model has solved platinum channel, reduced glass defect-platinum particle, the damage of having avoided thermopair to bring when building by laying bricks or stones, saved expense, got rid of in passage building process and use procedure, because building method is improper, expand and the problem of the damage that oxidation brings platinum channel body and thermopair.
The utility model is the zirconium white disperse to be formed the disperse zirconium in the platinum molecule; form protective layer at the platinum body surface; can strengthen the anti-volatility of platinum body under hot environment; and enhancing platinum body intensity; but prolongs life 6-9 month; the glass defect that effective minimizing is caused by the recovery of platinum body-platinum particle 20-30%, production brings great economic benefit to base plate glass.In the passage temperature-rise period, note the thermopair changing conditions.But the platinum channel building process carries out clean the process work-ing life of extending channel and the safety in production of passage to the platinum surface, to the processing of thermopair be for reduce thermopair heat up and production process in damage, platinum channel is built the lagging material that adopts unlike material by laying bricks or stones and namely can be saved cost and do not affect passage normal production not only but also can optimize via process.
