Problems solved by technology

[0003] However, it is difficult to identify with the naked eye on surface deformation and surface micro-scratches, and specific equipment is required to remove surface deformation and surface micro-scratches. Scratches or micro-deformations on the surface of the inner tube will affect the later heat-absorbing film electroplating. make an impact
[0004] Moreover, the traditional cleaning method is time-consuming and wastes a lot of water resources. The process is too complicated and the output is reduced.

Embodiment Construction

[0035] 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.

[0036] A kind of processing technology of tube in vacuum tube, this processing technology comprises the following steps:

[0037] 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;

[0038] b. Inner tube production: Put quartz, borax, calcite, mirabilite, sodium hydroxide, and nano-sized titanium powder into the melting and filtering, then put in nano-sized barium carbonate and stir evenly, and finally press the film to press the raw materials into glass Inner pipe semi-finished products and exhaust nozzles;

[0039] c. Round head firing: soften and melt the end of the inner tube...

Abstract

The invention provides a machining technology for vacuum pipe inner pipes, and belongs to the technical field of glass manufacturing. The machining technology solves the technical problem that the existing vacuum pipe inner pipe production efficiency is low. According to the machining technology for the vacuum pipe inner pipes, the machining technology comprises the first step of raw material out-purchasing, the second step of inner pipe manufacturing, the third step of round head firing, the fourth step of annealing and the fifth step of drying cleaning. The machining technology 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 of a vacuum tube inner 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, it is difficult to identify with the naked eye on surface deformation and surface micro-scratches, and specific equipment is required to remove surface deformation and surface micro-scratches. Scratches or micro-deformations on the surface of the...
