Embodiment Construction

[0036] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0037] A process for processing an outer tube of a vacuum tube, the process comprising the following steps:

[0038] a. Outsourced raw materials: purchase existing quartz, borax, calcite, Glauber's salt, sodium hydroxide, nano-scale titanium powder and nano-scale barium carbonate as raw materials in the market;

[0039] b. Production of the outer tube: put quartz, borax, calcite, mirabilite, sodium hydroxide, and nano-scale titanium powder into the glass through melting and filtering, then put in nano-scale barium carbonate and stir evenly, and finally press the film to press the raw materials into glass Outer pipe semi-finished products and exhaust nozzles;

[0040] c. Round head firing: soften and melt the outer tube in...

Abstract

The invention provides a machining process of a vacuum pipe outer pipe, and belongs to the technical field of glass manufacturing. The technical problem that the production efficiency of an existing vacuum pipe outer pipe is low is solved. The machining process of the vacuum pipe outer pipe includes the following steps of a, raw material outsourcing; b, outer pipe manufacturing; c, round head firing; d, deflator connecting; e, annealing; and f, drying and cleaning. The machining process has the beneficial effect that the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of glass manufacturing, in particular to a processing technology for an outer tube of a vacuum tube. Background technique [0002] Traditional glass tubes used to make vacuum tubes need to be manually inspected for appearance, straightness, concentricity, wall thickness, length, diameter, scratches, surface deformation, etc., and then the qualified products are cleaned and dried. The traditional cleaning process is to clean the glass tube. The sequence is to spray it with tap water first, then wash it with cleaning solution, and finally wash it with deionized water to ensure the cleanliness of the glass tube before coating, and then enter the drying step. [0003] However, cleaning in this way is time-consuming, and a large amount of water resources will be wasted at the same time, and the process is too complicated, which reduces the output. Contents of the invention [0004] The purpose of the present i...
