Description
Technical field
The utility model relates to the purification techniques field of glass sand, more specifically, relates to a kind of device of rejecting gas liquid inclusion in glass sand.
Background technology
Silica glass is one-component SiO
2extraordinary high-grade glass, there is fabulous chemical stability, infrared spectra transmitance be high, shock resistance is strong, high temperature resistant (more than 1800 degree Celsius) indeformable, resistance to X-x radiation x, electrical isolation special excellent physics, chemical property.Be extensively production of polysilicon, photoelectric source, electronic industry, optical communication, medical instrument, SiO
2thin-film material, large-scale integrated circuit, laser, aerospace, military industry etc. provide tip materials, are indispensable in high-tech.
In mid-term in last century, people's mineral crystal is raw material production silica glass, can widely apply along with it, and crystal ore deposit close to exhausted, can not meet the fast development of modern high technology industry already.In decades, new batching produced by the silica glass that people have to explore alternative crystal.
Relative to crystal, quartz mine contains more impurity.Its impurity can be divided into structure composition impurity and unstructuredness impurity.Unstructuredness impurity is the impurity outside quartz mine crystal, as surface adhesion thing, associated mineral.Current impurity clearance technique, as: the serial means such as shrend, flotation, pickling, magnetic separation, high-temperature vacuum process, chlorination, superconduction choosing, electric separation, ultrasonication, doping purification can meet silica glass requirement substantially.Structural impurity refers to the impurity formed when quartz mine crystal growth, also referred to as microdefect, as gas liquid inclusion, gas liquid inclusion at room temperature primarily of the two-phase inclusion of liquid phase and small bubbles composition, this be along with during mineral growth by H
2, O
2, N
2, CO, CH
4, CO
2, H
2o etc. are wrapped in the structural impurity formed in quartz crystal, and existing Technology is difficult to eliminate this type of defect at all, and it is also the important factor affecting silica glass purity and performance.
Generally containing fluid inclusion in quartz mine, current existing technique is difficult to remove.
Countries in the world are in the eighties in 20th century, China, the U.S., Japan, Russia, France, Germany etc. all achieve with common quartzy silicon ore deposit by with cleaning after hydrofluoric acid dips, high-temperature calcination, shrend, electric separation, flotation, magnetic separation, " chloroazotic acid " soak the selected processing purifications of means such as even high temperature floatingly boils, high-temperature vacuum process, chlorination, superconduction choosing, ultrasonic wave, doping purification for a long time, makes its acrobatics except gas liquid inclusion reject and can replace crystal completely.But it is still helpless for the rejecting to greatest extent of the gas liquid inclusion in the tiny crystals in glass sand.Even if the product of current U.S. You Niming (Unimin) company of calling oneself with " world standard purity ", micro-about 50PPM is also also had to exist.According to researchs such as Hou Qinglin, the gas liquid inclusion in the so-called glass sand of oneself purification of the quartz mine on the ground such as import Angola of China, Madagascar is still at more than 120PPM.Although also most of gas liquid inclusion can be removed by beating to stick together, still have structural gas liquid inclusion to become scattered about during silica glass sticks together, make to be subject to very big limitation by the purposes of quartz sand production silica glass.
In existing quartz sand, the minimizing technology of gas liquid inclusion mainly contains: soda acid difference of corrosion method, cold/thermal spalling method, chlorination degassing method, microwave radiation-pickling process etc., it removes the effect or not satisfactory of gas liquid inclusion, or it is too complicated, operated and become to there is potential safety hazard, production technique not environmentally.
Prior art is that glass sand is first produced tiny crack by microwave treatment, and then is made impurity in the inclusion of generation tiny crack discharge by acid etching.And utilize the utility model device, by the glass sand regulating the accurate processing condition of microwave treatment to obtain, its gas liquid inclusion content is very low, and amount is also little, successfully abandons acid etching step, avoids the severe of environmental pollution and operational condition.
The utility model apparatus structure is simple, easy to use, Environmental Safety, reject effective, common quartz mine is not only made to replace the mineral crystal of resource exhaustion to become possibility, and can also produce and reduce the glass sand of a more than order of magnitude than gas liquid inclusion content in mineral crystal, for major contribution is made in the raw material replacement upgrading of silica glass.
