How to choose barrier explosion-proof materials

Both metal filling materials and non-metal filling materials will have a good explosion-proof and explosion-proof effect on the fuel tank, and no charge accumulation will occur during use. How to choose materials? The advantages of the mesh aluminum alloy filling material are: long life and easy maintenance; good compatibility with oil products; good thermal conductivity; no pollution after scrapping; but the oil products after filling explosion-proof materials will be slightly heavier. The advantages of the mesh polyurethane filling material are: light weight; low cost; but compared to aluminum alloy materials, its volume and the adsorption residue of fuel occupy a part of the available device capacity.
