Muaj peb hom fiberglass grating ntau lawm txheej txheem: reciprocating fiber ntau winding, nruam fiber ntau winding, thiab centrifugal casting.
Reciprocating Fiber Winding (ib txoj kev kho - ntev): Hauv cov txheej txheem no, lub tank impregnation reciprocates nrog lub mandrel rotating. Ntev fiberglass filaments yog nteg ntawm ib lub kaum sab xis ntawm lub mandrel axis. Lub kaum sab xis winding yog tswj los ntawm qhov sib piv ntawm lub impregnation tank qhov txav ceev mus rau mandrel txoj kev sib hloov ceev. Translational txav ntawm lub impregnation tank yog computerized electromechanical tswj. Tus naj npawb ntawm cov khaubncaws sab nraud povtseg maj mam nce mus txog thaum tsim cov phab ntsa tuab. Tom qab winding, cov resin nyob rau hauv cov khoom yog yeej kho. Tom qab kho, lub mandrel raug tshem tawm ntawm lub fiberglass raj.
Continuous Fiber Winding (ib txoj hauv kev txuas mus ntxiv): Hauv cov txheej txheem no, lub raj txav los ntawm qhov chaw noj mov uas muab cov khoom sib xyaw ntawm cov cob-impregnated untwisted roving, tws fiberglass fibers, thiab resin xuab zeb. Lub raj yog tsim raws li lub mandrel txuas ntxiv mus.
Cov txheej txheem centrifugal casting (ib txoj kev ruaj khov- ntev): Hauv cov txheej txheem no, txiav iav fiber reinforcement thiab xuab zeb tau muab tso rau hauv cov pwm hlau ruaj rau cov kabmob. Unsaturated resin nrog lub catalyst yog txhaj rau hauv ib kawg ntawm cov pwm, impregnating qhov cuab lub zog. Under centrifugal force, the resin displaces air from the fibers and fillers, creating a dense, non-porous composite material. Vim yog lub zog centrifugal, ib tug du, resin- nplua nuj txheej txheej sab hauv ntawm cov yeeb nkab phab ntsa, uas tom qab ntawd kho ntawm qhov kub thiab txias. Cov kav dej uas siv cov qauv no tseem hu ua fiberglass reinforced yas (FRP) xuab zeb-cov kav dej.
Muaj ntau ntau cov tuam txhab lag luam thoob ntiaj teb siv cov txheej txheem fiber ntau reciprocating dua li cov siv ob txoj kev. Ib qho laj thawj yog tias cov kav dej FRP tsim los siv cov txheej txheem no muaj ntau yam kev siv thiab kev siv tau zoo dua.
