Abstract
The invention discloses a production process of an environmental-friendly quartz tube. The production process includes: adding essential element materials into quartz sand and mixing, dipping the mixture in hydrofluoric acid having a concentration of 50% for 1-2 min, drying the mixture, subjecting the dried mixture to smelting, burning and tube pulling, subjecting the quartz tube to primary vacuum high-temperature dehydroxylation, doping titanium, europium and cerium into the dehydroxylated quartz tube, performing high-temperature burning and tube pulling, subjecting a firmed tube to vacuum high-temperature dehydroxylation, detecting the quartz tube and preparing into a finished products if the quartz tube is qualified in detection. The production cost is low. The quartz tube can effectively filter ultraviolet ray in short-wave band lower than 340 [mu]m, reduce generation of ultraviolet ray harmful to human body, and reduces generation of ozone, thus achieving effects of environment protection.
Description
Technical field
The present invention relates to a kind of production technique of environmental protection silica tube, relate in particular to a kind of harmful short wave ultraviolet and carry out the effectively production technique of the environmental protection silica tube of filtration.
Technical background
There is following defect in the production method of silica tube of the prior art: the purity of raw material quartz sand is high, originate in doping unreasonable, the silica tube of producing can not reach good filter effect to ultraviolet filtration, in the time of long-time use, it produces harmful shortwave, and human body is produced to harm.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of simple and easy, with low cost, effectively ultraviolet ray below filter 23 40 μ m of producing is provided, reach the production technique of the environmental protection silica tube of controlling short wave ultraviolet generation.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of production technique of environmental protection silica tube, to adding the mixing of adulterating of necessary element material in quartz sand, mixture is soaked to 1-2 minute in 50% hydrofluoric acid, after baking mixture, carry out melting calcining trombone slide, silica tube is carried out to the processing of preliminary vacuum high-temperature deshydroxy, deshydroxy silica tube Doped with Titanium, europium, cerium are carried out to high-temperature calcination trombone slide, to becoming pipe to carry out the processing of vacuum high-temperature deshydroxy, silica tube is detected, detect after qualified and prepare finished product.
The mixture mixing in described doping step comprises aluminum oxide, boron oxide, barium oxide and Lithium Oxide 98min, and described titanium, europium, cerium are respectively titanium oxide, europium nitrate and cerous nitrate.
In described melting calcination process, by first working chamber vacuum-treat, then working chamber's temperature is risen to 2000-2500 DEG C, keep constant after, carry out the roasting of 4-5 hour, in roasting process, keep inner vacuum state.
Described vacuum high-temperature deshydroxy treatment step is the product after having calcined to be carried out to the vacuum high-temperature deshydroxy of 1200-1300 DEG C, and the deshydroxy time keeps 2-4 hour.
Compared with prior art, the beneficial effect having is: low production cost, and silica tube can be effectively by the ultraviolet filtering of the following short-wave band of 340 μ m, and the ultraviolet ray that reduces harmful human body produces, and can also reduce the generation of ozone, reaches the effect of environmental protection.
Embodiment
Embodiment, a kind of production technique of environmental protection silica tube, in quartz sand, peace ratio adds aluminum oxide, boron oxide, the mixing of adulterating of the element material such as barium oxide and Lithium Oxide 98min, utilize mixing and blending machine to carry out the uniform stirring of 20 minutes, , mixture after stirring is carried out to 50% hydrofluoric acid dips 1-2 minute, raw material after mixture is dried carries out high-temperature smelting pot melting calcining trombone slide, in described melting calcination process by first working chamber vacuum-treat, then working chamber's temperature is risen to 2000-2500 DEG C, keep constant after, carry out the roasting of 4-5 hour, in roasting process, keep inner vacuum state, silica tube is carried out to the processing of preliminary vacuum high-temperature deshydroxy, vacuum high-temperature deshydroxy treatment step is the product after having calcined to be carried out to the vacuum high-temperature deshydroxy of 1200-1300 DEG C, the deshydroxy time keeps 2-4 hour, to deshydroxy silica tube adulterated TiOx, europium nitrate and cerous nitrate are carrying out high-temperature calcination trombone slide, to becoming pipe to carry out the processing of vacuum high-temperature deshydroxy, silica tube is detected, detect after qualified and prepare finished product.
