Problems solved by technology

Most of the existing explosion-proof storage containers are made of aluminum alloy barrier explosion-proof materials. Due to the chemical composition of the explosion-proof materials, there are problems and shortcomings: 1. Poor pressure resistance
It is easy to break when encountering liquid or gaseous pressure, which can easily lead to pipeline blockage; 2. Weak corrosion resistance
Because the molecular structure of metal aluminum is not tight enough, it is easy to oxidize when it encounters corrosive liquids and gases such as acid and alkali, and its corrosion resistance is extremely poor.
3. Short service life
Because metal aluminum is easy to oxidize and corrode when it encounters corrosive liquids and gases such as acids and alkalis, and liquid and gaseous pressures, resulting in a short service life; 4. The barrier and anti-knock performance is unstable
The ductility of metal aluminum is weak, and it is easy to deform when it encounters high-pressure liquid and gaseous substances, and has no reducibility of solid substances. After a certain period of use, the adhesion area of ​​flammable and explosive liquid and gaseous substances decreases, resulting in anti-explosive force. to weaken

Abstract

The invention discloses a titanium-magnesium alloy explosion-proof material, which comprises a sheet-like body whose surface is covered with mesh through holes, and its chemical composition includes Ti, Mn, Cr, Si, Zn, Mo, Hf, Sn and Mg; The formula design is unique and reasonable, adding Ti and Mg, and the reasonable ratio of Mn, Cr, Si, Zn, Mo, Hf and Sn alloy element content, effectively improving the corrosion resistance, yield strength and tensile strength , and adopts a double-layer structure, the mesh and the through hole are at a certain angle, so that a number of small compartments with a certain barrier effect are formed in the container, which can not only effectively inhibit the spread of flames, but also have good thermal conductivity, which can quickly Absorb most of the heat released by combustion, so that the final temperature after the combustion reaction is greatly reduced, the expansion program of the reaction gas is reduced, and the pressure value of the container increases very little, which conforms to the effect, has good explosion suppression performance, and is beneficial to Widely promote and apply.

Description

technical field [0001] The invention belongs to the technical field of explosion-proof materials, and in particular relates to a titanium-magnesium alloy explosion-proof material. Background technique [0002] In the storage container of flammable, explosive liquid and gaseous hazardous chemicals, in order to prevent the medium from burning or exploding due to accidents such as static electricity, open flames, and gunshots, an explosion-proof material is filled in the container. Explosion-proof materials are based on the heat conduction theory and the basic conditions for combustion and explosion. The high-porosity honeycomb structure of the material is used to prevent the rapid spread of flames and the instantaneous release of energy. At the same time, the surface effect of the material is used to absorb a large amount of energy and destroy the explosion conditions of the combustion medium. , thus preventing the occurrence of combustion and explosion. [0003] In modern so...
