Problems solved by technology

[0002] The production of traditional glass tubes mainly adopts the method of manual drawing, and the outer diameter of the produced glass tubes is relatively large. Taking the T8 glass tube as an example, the outer diameter of the glass tubes drawn manually is generally 24-27mm, so that the glass tubes It is difficult to solve the problems of outer diameter tolerance and wall thickness tolerance; in addition, the glass tubes produced have burrs at both ends, which brings great disadvantages to operation and transportation, and is easy to scratch hands, feet, etc.

Description

technical field [0001] The invention belongs to the technical field of glass materials, and in particular relates to a 3650nm ultraviolet-transmitting blue-black glass tube and a preparation method thereof. Background technique [0002] The production of traditional glass tubes mainly adopts the method of manual drawing, and the outer diameter of the produced glass tubes is relatively large. Taking the T8 glass tube as an example, the outer diameter of the glass tubes drawn manually is generally 24-27mm, so that the glass tubes The outer diameter tolerance and wall thickness tolerance problems are difficult to solve; in addition, the glass tubes produced have burrs at both ends, which brings great disadvantages to operation and transportation, and is easy to scratch hands and feet. Contents of the invention [0003] The purpose of the present invention is to invent a blue-black glass tube through ultraviolet rays and a preparation method thereof. [0004] The UV-transmitt...
