Problems solved by technology

[0002] At present, the known fuse brackets are made of ceramics, but the manufacturing process of ceramics is complicated and the precision is not high, and the degree of fit is not good.
These materials have poor insulation at instantaneous high temperature, and the mechanical strength is not enough, and they are explosive, and there is a certain danger in the protection circuit. Often, the circuit is burned due to the quality of the fuse, resulting in immeasurable wealth for the masses. loss

Abstract

The invention relates to a production method of a quartz glass tube for a fuse bracket, the preparation steps of which are as follows: the quartz stone raw material is used to obtain quartz sand; the quartz sand is put into sodium nitrate to remove impurities for the first time, and then carry out High-temperature roasting; after soaking in mixed acid, cleaning, dehydration and drying, aluminum nitrate nonahydrate is used for second impurity removal, and after impurity removal, high-temperature roasting, mixed acid soaking, flotation, dehydration and drying are performed to obtain high-purity quartz sand Add titanium dioxide as an additive to high-purity quartz sand, melt and draw it into a quartz glass tube, and then process it to obtain a finished product. The present invention adopts a scientific and reasonable method to purify raw materials, physically remove impurities, chemically purify, and remove gaseous impurities at high temperature for comprehensive purification to produce high-purity quartz sand that meets product requirements, and then smelts and draws the obtained high-purity quartz sand to produce have to. Moreover, continuous production is possible, the production efficiency is high, and the production cost is low, and the prepared glass tube for the fuse holder has high precision.

Description

technical field [0001] The invention relates to a production method of a quartz glass tube, in particular to a production method of a quartz glass tube for a fuse bracket. Background technique [0002] At present, the known fuse holder is made of ceramics, but the manufacturing process of ceramics is complicated and the precision is not high, and the fit is not good. These materials have poor insulation at instantaneous high temperature, and the mechanical strength is not enough, and they are explosive, and there is a certain danger in the protection circuit. Often, the circuit is burned due to the quality of the fuse, resulting in immeasurable wealth for the masses. loss. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new production method of quartz glass tubes for fuse brackets, which is easy to operate, highly controllable, and can effectively improve the quality of the brackets. [0004] The technical pr...
