Problems solved by technology

[0002] Since the current ordinary UV filter quartz glass tube has a transmittance of 200-320μM and cannot completely filter out, when it is made into a lamp, part of the ultraviolet rays that cannot be filtered out will cause harm to the human body and accelerate the aging of the car paint.

Abstract

The invention discloses a low-hydroxyl yellow light-filtering quartz tube and a preparation method thereof. The low-hydroxyl yellow light-filtering quartz tube is prepared from the following raw materials by optimal weight percent: 94% to 99% of quartz sand with high purity, 0.1% to 0.5% of cobaltous oxide, 0.1% to 2% of ceric oxide, 0.1% to 0.5% of europium oxide, 0.1% to 0.5% of aluminum oxide, 0.1% to 0.5% of titanium oxide, 0.1% to 0.5% of potassium oxide and 0.1% to 0.5% of sodium oxide. The low-hydroxyl yellow light-filtering quartz tube also has the advantage of being more reasonable in formula matching besides having the advantages of the ordinary ultraviolet-filtering quartz glass tube. According to the testing of a conventional method, the compressive strength of the low-hydroxyl yellow light-filtering quartz tube is greatly improved while the damage of an automobile lamp to a baking varnish is greatly decreased due to the addition of multiple metal oxides and rare earth elements; the safety performance of the low-hydroxyl yellow light-filtering quartz tube is improved at the same time.

Description

technical field [0001] The invention relates to a quartz tube, in particular to a low-hydroxyl yellow filter quartz tube; the invention also relates to a preparation method of the low-hydroxyl yellow filter quartz tube. Background technique [0002] Since the current ordinary UV filter quartz glass tube has a transmittance of 200-320 μM and cannot completely filter out, when it is made into a lamp, part of the ultraviolet rays that cannot be filtered out will cause harm to the human body and accelerate the aging of the car paint. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quartz tube with a more reasonable formula ratio and completely filter harmful ultraviolet rays below 320 μM in view of the deficiencies of the prior art. [0004] Another technical problem to be solved by the present invention is to provide a preparation method of the above-mentioned low hydroxyl yellow filter quartz tube. [0005] The ...
