Abstract

The invention discloses an explosion-proof wall manufactured through foamed aluminum of a sandwich structure. According to the technical scheme, the explosion-proof wall is characterized in that a foamed aluminum slab of the sandwich structure and having specific characteristics is used for manufacturing the explosion-proof wall, and flame-retardant, and explosion-proof and energy-absorbing characteristics of foamed aluminum materials are used for safety protection of factories or urban districts or equipment. Injury to staff can be effectively prevented when a fire, an explosion and other accidents happen to the equipment, and the explosion-proof wall has the good functions of sound insulation, thermal insulation and electromagnetic shielding.

Description

Technical field: [0001] The invention relates to an explosion-proof wall adopting aluminum foam in a sandwich structure, which belongs to the field of industrial equipment. Background technique: [0002] Aluminum foam is made by adding additives to pure aluminum or aluminum alloy and undergoing a foaming process, which has both metal and bubble characteristics. It has the characteristics of small density, high impact absorption ability, high temperature resistance, strong fire resistance, corrosion resistance, sound insulation and noise reduction, low thermal conductivity, high electromagnetic shielding, and strong weather resistance. Sound insulation, building fire protection and other fields have been applied. [0003] The energy absorption of aluminum foam has good rate-strain characteristics, that is, the greater the strain rate, the greater the energy absorbed per unit volume of aluminum foam, up to 8-30J / cm 3 . This performance of foamed aluminum makes it the most...
