Embodiment

[0040] Preparation of hydrogen storage material LaNi 5 Alloy button ingots are formulated according to the design composition, and the metal purity (at%) used is La99.3% and Ni99.9%. Clean the above-mentioned raw materials with an ultrasonic oscillator, then distribute the weight according to the design composition, put the prepared material in a water-cooled copper mold, and melt it in an electric arc furnace under the protection of an argon atmosphere. During the melting process, the alloy is turned over and weighed. Melt five times while carrying out electromagnetic stirring to ensure the uniformity of the alloy. After smelting, seal the alloy ingot in a vacuum quartz tube, put it into a heat treatment furnace, heat it up to 1100°C for 8 hours, and then quench it. LaNi was then performed on this comprehensive test facility 5 Hydrogen storage performance test of hydrogen storage materials, the purity of hydrogen used is 99.99999%. 1 to 2 grams of pulverized samples are pu...

Abstract

This invention relates to a computer controlling device of performance testing of hydric material storage equipped with computer program, and is composed of the main body of computer with controlling programs. The mainframe collects the data of the temperature and the pressure transmitters through the program and the multi-functional data collecting card, and controls the switches of the electrical valve and the electromagnetic valve. And meanwhile, it sends the contact signal to the counting relay. The control program is composed of PCT curve testing module, the temperature and pressure history curve module, the dynamics testing module, the cycle life-span testing module and exiting module. This invention has strong automatic capacity, high reliability, complete testing parameters, high precision of testing, wide applying area, low cost.

Description

technical field [0001] The invention relates to a material performance testing technology, in particular to a computer control device for hydrogen storage material performance testing equipped with a computer program. Background technique [0002] At present, with the depletion of fossil energy sources approaching and human pursuit of a clean environment, hydrogen energy will play an increasingly important role. In recent years, governments of various countries have invested heavily in research on technologies related to hydrogen energy utilization. Judging from the current technological development, the storage and transportation of hydrogen is one of the technical bottlenecks of hydrogen energy utilization. Among them, the research on high-performance hydrogen storage materials is a current research hotspot. During the research process of hydrogen storage materials, it is necessary to continuously measure and evaluate the performance parameters related to the materials. ...
