JOESCO blast walls have excellent explosion-proof performance,through the domestic and international recognition of multiple testing and certification;When gas explosion happened,and every wall in a short period of time under a very large explosion load,elastic-plastic deformation will occur,this to its structural reliability is put forward high request.Compared with other kinds of explosion-proof measures, critical wall insulation construction cost is low,set up quickly, the unit of high strength,very adapt to the requirement of explosion protection,suddenly and violently wall used to separate the workspace and living areas,bear the main load of the explosion,to protect workers and production facilities,has a very important role for reducing accident damage.
