Process for manufacturing basalt capillary tube by using stretching method

Abstract

The invention discloses a process for manufacturing a basalt capillary tube by using a stretching method, and relates to the technical field of manufacturing of hydrogen storage capillary tubes. The method comprises the following steps: S1, selecting a proper basalt ore raw material, adding the basalt ore raw material into a crusher for crushing, screening the crushed basalt through a screening machine with a 200-300-mesh screen, removing large-particle basalt, and storing the basalt raw material cleaned by deionized water in a stock bin for later use; and S2, conveying the basalt stored in the step S1 to a quantitative feeder through a lifting conveyor, and feeding the basalt into a unit melting furnace. The hollow basalt microtube prepared by the method has the characteristics of high strength, corrosion resistance, acid and alkali resistance and the like; the basalt capillary tube is very suitable for being used as a high-pressure hydrogen storage material, the viscosity of basalt molten liquid is reasonably adjusted, the preparation quality is improved, the preparation uniformity of the capillary tube is guaranteed, and the phenomenon that the inner diameter of a local pipelineis large or small in the wire drawing process due to insufficient viscosity is avoided.

Description

technical field [0001] The invention relates to the technical field of making hydrogen storage capillary tubes, in particular to a process for making basalt capillary tubes by stretching. Background technique [0002] With the development of economy and society, non-renewable energy such as petroleum and coal can no longer meet the needs of human beings. Hydrogen has a high combustion calorific value, and the combustion products are non-polluting and recyclable, so it is the most potential new energy source. [0003] The key to realizing large-scale and widespread application of hydrogen energy lies in the research and development of cheap and efficient hydrogen production technology and safe and efficient hydrogen storage technology. The industrial production of hydrogen through electrolysis of water is an effective means to obtain clean and sustainable energy hydrogen fuel on a large scale. The research on efficient hydrogen production electrode catalytic materials and ef...
