AI Technical Summary
Existing air-raid shelter doors are difficult to transport, require advanced installation techniques, are difficult to maintain, and are difficult to convert between peacetime and wartime use, thus failing to meet the demand.
Using polymer composite material pultrusion molding technology, raw materials such as epoxy resin, graphene composite material, basalt fiber and glass fiber are used to prepare door frame profiles through dip-coating and suspension tensioning processes. Combined with curing agent and release agent, lightweight, corrosion-resistant and high-temperature resistant standardized components are formed.
It reduces packaging and transportation costs, simplifies installation requirements, improves the corrosion resistance and aging resistance of door frame profiles, realizes standardized production of polymer composite materials, reduces the need for later maintenance, and enhances the bending strength and airtightness of door frame profiles.
