The preparation of b, reinforcement body:
Get the 1/4 split reinforcement internal mold that step a prepares, steel construction positioner is used to be fixed on chimney air flue cylindrical shell by reinforcement internal mold, then use 3 to 4 layers to infiltrate the short of resin and cut felt, reinforcement internal mold and cylindrical shell are bonded together, after solidification, remove steel construction positioner, then by step identical above, other 3 1/4 reinforcement internal molds installations are bonded on cylindrical shell, then the interface of each reinforcement internal mold is used 3 to 4 layers short and cut the complete ring stiffener internal mold of the bonding formation of felt one, then according to the size of mode diameter in chimney air flue cylindrical shell and ring stiffener, pass through computer program, a point hop count is set etc., adjustment is wound around dolly starting position, ring stiffener internal mold rotates the winding yarn driving and infiltrate resin, winding dolly automatically moves back and forth, be wound around yarn to spin on cylindrical shell winding, until be wound to the thickness of setting.
Preferably, the entirety of above-described fiber glass reinforced plastic chimney flue is wound around the preparation method of reinforcement, and the reinforcement internal mold (1) described in step a can adopt isophthalic or vinylite to make.
Preferably, the entirety of above-described fiber glass reinforced plastic chimney flue is wound around the preparation method of reinforcement, and the resin described in step b is consistent with the structure sheaf resin of cylindrical shell.
Preferably, the entirety of above-described fiber glass reinforced plastic chimney flue is wound around the preparation method of reinforcement, and step a prepares reinforcement internal mold (1) and do not need to carry out polyurethane foam.
Beneficial effect: compared to the prior art the preparation method of the Wrapping formed reinforcement of entirety of fiber glass reinforced plastic chimney flue provided by the invention has the following advantages:
The preparation method of the Wrapping formed reinforcement of entirety of fiber glass reinforced plastic chimney flue provided by the invention, according to the design feature of chimney air flue reinforcement, by the preparation method of great many of experiments screening reinforcement internal mold, then by the Wrapping formed preparation technology of great many of experiments screening reinforcement body, whole process operability is strong, fiber glass reinforced plastic chimney and reinforcement body can be Integratively formed, and mechanical property is more excellent; Semicircle reinforcement cross section is smooth gently, can effectively avoid stress raisers phenomenon, do not need in preparation process to carry out polyurethane foam to reinforcement, greatly can reduce the installation difficulty of reinforcement internal mold, and can do mechanization operation, production efficiency is higher, and cost is lower, and continuous winding silvalin makes reinforcement can ensure structural intergrity and the surface that can obtain smooth and beautiful appearance, can overcome many deficiencies of prior art.
