Powder explosion suppressant for suppressing titanium powder explosion and preparation method of powder explosion suppressant

Abstract

The invention relates to a powder explosion suppressant for suppressing titanium powder explosion and a preparation method of the powder explosion suppressant, and belongs to the technical field of explosion suppressants. The powder explosion suppressant for suppressing titanium powder explosion is composed of a plurality of powder materials, and the powder explosion suppressant comprises the following components in percentage by weight: 13.2%-26.5% of ammonium dihydrogen phosphate, 17.4%-30.9% of sodium pyrophosphate decahydrate, 15.3%-28.2% of bismuth subcarbonate, 10.6%-23.7% of stannous chloride, 3.9%-8.6% of sodium methyl silicate and 5.8%-10.2% of sodium hexametaphosphate. According to the powder explosion suppressant for inhibiting the titanium powder explosion, all the components are matched according to a special proportion, so that the powder explosion suppressant has a very good synergistic explosion suppression effect, and the powder explosion suppressant for suppressing the titanium powder explosion further has the advantages of being good in explosion suppression performance, small in dosage, easy to prepare and the like; The powder explosion suppressant for suppressing the explosion of the titanium powder is particularly suitable for an explosive region of the titanium powder, and the explosion risk is reduced.

Description

technical field [0001] The invention relates to an anti-explosion agent, in particular to a powder anti-explosion agent for suppressing the explosion of titanium powder and a preparation method thereof. Background technique [0002] Titanium powder is an inevitable product in the production and processing of aerospace, spraying, metallurgy, fireworks and other industries. It not only causes occupational diseases and endangers the health of employees, but also has explosive properties. Once an explosion occurs, it will cause casualties and property losses. Serious threat to safe production. Titanium powder explosion suppression technology is an important means to prevent titanium powder explosion, and the core of explosion suppression technology is to research and develop anti-explosion agent with better explosion suppression performance. [0003] At present, limestone is a common powder explosion suppressant for titanium powder explosion. When titanium powder explodes, lime...

AI Technical Summary

Problems solved by technology

[0003] At present, limestone is a common powder explosion suppressant for titanium powder explosion. When titanium powder explodes, limestone powder is spread to reduce the oxygen concentration, so as to achieve the purpose of inhibiting the flame propagation of titanium powder explosion. However, limestone is easy to get wet and agglomerate and lose its flying ability , which weakens the effect of extinguishing flames, resulting in low explosion suppression efficiency and insufficient explosion suppression performance of rock powder
