With the development of urban construction and industry, the production and use of flammable and combustible hazardous chemicals are more and more important in industrial development and people's life. However, dangerous chemicals are often subject to accidents during storage and transportation, and the resulting losses are often immeasurable. Therefore, barrier explosion-proof materials for inhibiting or reducing the occurrence of explosion phenomena in the storage and transportation processes of dangerous chemicals are used, wherein alloy barrier explosion-proof materials are particularly widely applied.

Most of the traditional alloy barrier explosion-proof materials are of laminated structures, and the barrier explosion-proof materials of the structures are easy to break due to vibration and poor in acid and alkali resistance. For example, methanol and methanol fuels cannot corrode steel and stainless steel for a short period of time, but can corrode aluminum, brass, tin, copper, zinc and the like. The alloy mesh-shaped barrier explosion-proof material mainly comprises metals such as aluminum and magnesium, and has certain corrosion resistance, but has the problems of oxidation and aging, and the materials become brittle once aging, form fragments and fall into fragments when being vibrated, so that oil products are polluted or oil pipelines are blocked. Therefore, the alloy mesh barrier blast resistant material needs to be replaced periodically, increasing cost and labor. In addition, the process of the layered structure barrier explosion-proof material made of the alloy material is also complex, for example, the aluminum alloy barrier explosion-proof material is made of aluminum alloy foil through slitting and net pulling, then the net-shaped material is wound and finally filled and formed, the manufacturing process is complex, the net of the aluminum foil is damaged in the manufacturing process, and the corrosion rate is increased.

But this structure is not integrated into one piece, leans on tenon fourth of the twelve earthly branches structure to connect, has increased the instability, and the density and the degree of consistency in explosion-proof hole can't guarantee simultaneously.

In conclusion, the existing layered barrier explosion-proof material has the problems of oxidation and aging, and the material is easily damaged in the manufacturing process; and the spherical barrier explosion-proof material cannot achieve the optimal explosion-proof effect in the aspects of the density and the uniformity of explosion-proof holes.

Therefore, in order to avoid pollution to oil products or blockage of oil pipelines, barrier explosion-proof work is well done, and a nonmetal barrier explosion-proof unit which is convenient for mass production, can be integrally formed and has a spatial net structure is needed to solve the problems.
