Abstract

The invention provides a production method for a low oxyhydroxide and rare earth doping quartz tube. The production method comprises the following steps: carrying out raw material selection, dilution, stirring, drying, fusion, dihydroxylation and the like. The production method has the following advantages that a craft production flow is simplified, meanwhile, the quality of the quartz tube is further improved, the produced rose-colored, purple and black red quartz tubes meet market requirements; the produced rose-colored, purple and black red quartz tubes are used as the quartz glass tube of an electric heating tube, electric energy can be converted into the heat energy form of a far infrared ray to be transferred, infrared ray thermal transmittance is further improved, electricity consumption is further lowered, and more energy is saved for products.

Description

technical field [0001] The invention relates to the technical field of quartz tube manufacture, in particular to a production method of a low oxyhydroxide and rare earth doped quartz tube. Background technique [0002] Quartz glass tube is a special industrial technical glass made of silica, which is a very good basic material. Quartz glass has a series of excellent physical and chemical properties. , [0003] At present, there are many production methods of quartz tubes, and the types of quartz tubes can be roughly divided into the following types: transparent quartz tubes (outer diameter 1.5mm--300mm), ultraviolet filter quartz tubes, colored quartz tubes, etc. [0004] Patent Publication No. CN103387328B, the invention name is a production method of a low-hydroxyl rose-colored rare earth doped quartz tube, which records the production of a rose-colored quartz tube. The main production steps are roughly raw material selection, stirring, dilution, doping, and baking. Dry...
