Abstract

The invention discloses a production method of a low-hydroxylic bactericidal deodorant quartz tube. The production method comprises the following steps of 1, selecting high-purity quartz as a main material for production of the low-hydroxylic bactericidal deodorant quartz tube, and rhenium trioxide, titanium dioxide, europium sesquioxide and potassium dioxalate as auxiliary materials for production of the low-hydroxylic bactericidal deodorant quartz tube, wherein SiO2 content of the high-purity quartz is great than or equal to 99.95% and the quality of each one of rhenium trioxide, titanium dioxide, europium sesquioxide and potassium dioxalate is 0.1 to 5% of that of the high-purity quartz, 2, mixing uniformly the main material and the auxiliary materials by stirring and drying at a temperature of 200 DEG C by an oven to obtain a mixed material, 3, putting the mixed material into a continuous melting furnace to carry out melting at a temperature of 1800 to 2000 DEG C and carrying out direct production of a bactericidal deodorant quartz tube by traction produced by a tube drawing machine, and 4, putting the produced bactericidal deodorant quartz tube into a vacuum dehydroxylation furnace to carry out dehydroxylation at a temperature of 800 to 1050 DEG C for 3 to 8 hours to obtain a low-hydroxylic bactericidal deodorant quartz tube. The low-hydroxylic bactericidal deodorant quartz tube prepared by the production method has bactericidal and deodorant functions and is colorless and transparent, and thus enlarging a use scope of quartz tubes.

Description

technical field [0001] The invention belongs to the technical field of inorganic nonmetals, and in particular relates to a production method of a low-hydroxyl sterilizing and deodorizing quartz tube. Background technique [0002] As we all know, the traditional production method of sterilizing and deodorizing quartz tubes is the coating method, but at present, the continuous melting method is mostly used to produce sterilizing and deodorizing quartz tubes, for example: a red quartz tube, which uses high-purity quartz doped with rare earth element oxide triphosphorus Alum, europium oxide and magnesium oxide, alum triphosphide, europium oxide and magnesium oxide are respectively 0.1-5% of the quality of high-purity quartz. After mixing and drying, they are put into a continuous melting furnace to directly produce red quartz tubes. This method can only Produce a red quartz tube; two blue quartz tubes, which use high-purity quartz doped with rare earth oxides of alum triphosphid...
