Example Embodiment

[0011] A special anti-quenching quartz glass tube for green submerged liquid. In the high-purity quartz sand for producing the quartz glass tube, the weight of the high-purity quartz sand is taken as the basic weight, and the following raw materials are added:

[0012] Copper oxide 0.1~0.8‰, sodium chloride 0.001~0.01‰,

[0013] Ferric oxide 0.001~0.03‰, potassium nitrate 0.001~0.03‰,

[0014] Europium oxide 0.01~0.05‰, alumina 0.001~0.05‰,

[0015] Chromium trioxide or potassium dichromate 0.1~0.8‰,

[0016] Fully mix the above raw materials with high-purity quartz sand. When adding, first add sodium chloride, ferric oxide, potassium nitrate, aluminum oxide, chromium trioxide or dichromic acid that does not react with high-purity quartz sand at room temperature. Potassium is added to the high-purity quartz sand for mixing; then copper oxide and europium oxide are added to the high-purity quartz sand, and the tail gas is recovered, and then the sand is baked, cooled to room temperature...

Abstract

A green under-liquid special anti-quenching quartz glass tube is disclosed. In production of high purity quartz sands of a quartz glass tube, with the weight of the high purity quartz sands as basic parts by weight, raw materials are added in parts by weight as follows: 0.1-0.8/1000 of cupric oxide, 0.001-0.01/1000 of sodium chloride, 0.001-0.03/1000 of ferric oxide, 0.001-0.03/1000 of potassium nitrate, 0.01-0.05/1000 of europium oxide, 0.001-0.05/1000 of aluminum oxide and 0.1-0.8/1000 of chromic oxide or potassium dichromate. The raw materials adequately mixed with the high purity quartz sands enter into a furnace to smelt and then are drawn to required quartz glass tubes. The green under-liquid special anti-quenching quartz glass tube drawn and molded by the preparation process of integrally coloring the tube wall is uniform in integral coloring of the tube wall, is free from explosion and has high strength. The green under-liquid special anti-quenching quartz glass tube is a super strength anti-quenching quartz glass tube special for underwater or under-liquid lighting appliances.

Description

technical field [0001] The invention relates to a preparation technology of a quartz tube, in particular to a special anti-quenching quartz glass tube for green liquid. Background technique [0002] The thermal expansion coefficient of quartz glass is small, and it has the characteristics of high temperature resistance, ultraviolet and infrared transmission, etc. It has a large market demand and is now more and more widely used in the outer casing of industrial and civil heating products. At present, there is no dedicated quartz glass tube for underwater or liquid lighting appliances. Contents of the invention [0003] The technical problem to be solved by the present invention is to address the deficiencies of the prior art, and propose a special anti-quenching quartz glass tube for green liquid with uniform overall coloring of the tube wall, no tube explosion, and high strength. [0004] The technical problem to be solved by the present invention is achieved through the...
