Abstract
The invention provides a preparation method of a quartz glass lens tube. The preparation method includes the following steps that 1, a high-purity quartz raw material ranging from 60 to120 meshes in particle size is placed into a tungsten crucible of a continuous smelting furnace, wherein sio2 is larger than or equal to 99.999%; electrically-molten quartz material liquid is subjected to warm and heat sediment in the tungsten crucible at the temperature of 2200-250 DEG C, and after gas impurities and liquid impurities are discharged through an exhaust vent, the material liquid is formed; 3, a formed quartz tube is cut according to the required dimension of a pipe lens, and the quartz tube for the pipe lens is formed. The preparation method has the advantages that the high-voltage-resistant quartz tube is directly produced through a continuous smelting method, the raw material of the quartz raw material with the sio<2> being larger than or equal to 99.999% is adopted, the transparency of a produced product is improved, the high-voltage-resistance and high-temperature resistance of the product are enhanced, and the high-voltage resistance can be larger than or equal to 20.0 Mpa and 20 times that of ordinary glass; the continuous smelting method is adopted for one-step forming, and the preparation is convenient and easy to implement.
Description
Technical field
The present invention relates to illuminating product technical field, be specifically related to a kind of preparation method of silica glass detector tube.
Background technology
Current oil, chemical industry, chemical fibre, pharmacy, the industrial glass pipe visor of sewage disposal are the main accessories on industrial pipeline device.By glass visor, can observe the response situation of the flow medias such as liquid in pipeline, gas, steam at any time, supervision and supervision are produced, and avoid in process of production security incident occurring.Current pipeline viewing mirror mostly applied thickness is the simple glass pipe between 1-3mm, Φ 50-100mm, as pipeline viewing mirror window glass.But this kind of glass is high pressure resistant lower, hot sudden turn of events temperature < 60 DEG C, easily break and damage, reducing service efficiency, range of application is very limited simultaneously.
Summary of the invention
For solving the problems of the technologies described above, the present invention does further to improve to the method for producing above-mentioned Glass tubing and the steps include:
1) the high-purity quartz raw material (sio2 >=99.999%) of 60-120 order number is dropped in the crucible of continuous induction melting furnace depressed place;
2) through being energized the quartzy feed liquid of melting in the crucible of depressed place through the warm precipitation of 2200 DEG C, after venting hole Exhaust Gas impurity and liquid impurity, feed liquid is carried out shaping;
3) according to the requirement size of pipeline viewing mirror, the silica tube after shaping is cut, forms pipeline viewing mirror silica tube.
Be that the former that feed liquid flows through in continuous induction melting furnace carries out shaping by method shaping for feed liquid in described step (2).
Be that silica tube is pulled down through the tractor of variable frequency control the type of making by method shaping for silica tube in described step (2).
Be 380mm by the diameter of the former core bar in continuous induction melting furnace shaping for feed liquid in described step (2), the diameter of former material platform is 420mm.
Advantage: with the high pressure resistant silica tube of continuous smelting method direct production, be characterized in the starting material selecting quartz raw material sio2 >=99.999%, the product of production is not only enhanced the transparency, and enhances the high pressure resistant of product and resistance to elevated temperatures, high pressure resistant >=20.0Mpa is 20 times of simple glass; Continuous smelting method is one-step moulding, convenient and simple.
Embodiment
1) the high-purity quartz raw material (sio2 >=99.999%) of 60-120 order number is dropped in the crucible of continuous induction melting furnace depressed place;
