Abstract
The invention discloses a process for producing environment-friendly quartz tubes. The process comprises the following steps: adding necessary element materials into quartz sand for doping and mixing the raw materials, performing smelting, calcining and drawing, performing preliminary vacuum high-temperature dehydroxylation treatment on the quartz tubes, dopping TiO2 in the dehydroxylated quartz tubes for performing high-temperature calcining and drawing, performing vacuum high-temperature dehydroxylation treatment on the finished tubes, detecting the quartz tubes and preparing the finished product after the quartz tubes are detected to be qualified. The production process is low in cost, the prepared quartz tubes can effectively filter ultraviolet rays at the wave band of 220 mu m or below, ozone which is harmful to a human body is reduced, and an environment-protecting effect is achieved.
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 production technique that reduces ozone generation and filter the environmental protection silica tube of certain wave band.
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 ozone, and human body is produced to harm.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of produce simple and easy, with low cost, can effectively filter the ultraviolet ray below 220 μ m, reach the production technique of environmental protection silica tube of controlling ozone 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 necessary element material mixing raw material that adulterates to carry out melting calcining trombone slide in quartz sand, silica tube is carried out to the processing of preliminary vacuum high-temperature deshydroxy, to deshydroxy silica tube doped Ti, O2 carries 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.
The mixture mixing in described doping step comprises aluminum oxide, boron oxide, calcium, magnesium, iron, barium oxide, sodium oxide, potassium oxide and Lithium Oxide 98min.
In described melting calcination process, by first working chamber vacuum-treat, then working chamber's temperature is risen to 2000-2500 ℃, 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 ℃, and the deshydroxy time keeps 2-4 hour.
Compared with prior art, the beneficial effect having is: low production cost, silica tube can, effectively by the ultraviolet filtering of the following wave band of 220 μ m, reduce the ozone generation of harmful human body, 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, calcium, magnesium, iron, barium oxide, sodium oxide, the mixing of adulterating of the element material such as potassium oxide and Lithium Oxide 98min, utilize mixing and blending machine to carry out halfhour uniform stirring, raw material after stirring is carried out to 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 ℃, 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 ℃, the deshydroxy time keeps 2-4 hour, to deshydroxy silica tube doped Ti, O2 is 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.
