FRP yeeb nkab technical standard ntau lawm muaj peev xwm

Peb ua haujlwm ze nrog ntau lub koom haum International Standards xws li International Organization for Standardization (ISO), European Standards (EN), British Standard Institute (BSI), Deutsches Institut für Normung (DIN), American Society for Testing and Material (ASTM), American Society of Mechanical Engineers (ASME), American Water Works Association (AWWA) thiab American Petroleum Institute (API) kom txuas ntxiv txhim kho peb cov kav dej sib xyaw ua haujlwm thiab ua kom muaj kev ua raws li kev lag luam zoo tshaj plaws thiab cov qauv.

Peb txuas ntxiv filament winding tshuab yog qhov pov thawj tshaj plaws hauv kev lag luam yeeb nkab sib xyaw.Cov kav dej yog tsim los ntawm lub tshuab filament txuas ntxiv.Lub tshuab no muaj ib lub mandrel tsim los ntawm lub helical qhov txhab nruam steel band, txhawb nqa los ntawm cov kab teeb uas tsim cov duab cylindrical.Raws li lub mandrel tsim lem tsim ib tug multi-layered structural phab ntsa ntawm yuav tsum tau thickness.

Cov txheej txheem txuas txuas txuas ntxiv ua rau peb tsim cov kav dej nrog txoj kab uas hla mus txog DN 4000 mm.

Cov kav dej yog tsim los siv cov txheej txheem helical (reciprocal) filament winding txheej txheem los ntawm impregnated iav fiber reinforcement nrog resin yog siv rau hauv precision steel mandrel nyob rau hauv ib qho kev cai qauv.Rov ua daim ntawv thov ntawm wetted fibers ua rau muaj ntau txheej txheej txheej phab ntsa kev tsim kho ntawm qhov xav tau tuab.

Cov txheej txheem helical winding ua rau peb tsim cov kav dej nrog txoj kab uas hla mus txog DN 1600 mm.

Cheebtsam ntawm Composite Materials Qhov kev xaiv ntawm fiber ntau tswj cov khoom ntawm cov khoom sib xyaw.Carbon, iav, thiab Aramid yog peb hom fibers loj uas siv hauv kev tsim kho.Cov khoom sib xyaw feem ntau muaj npe los ntawm kev txhawb nqa fiber ntau, piv txwv li, CFRP rau Carbon Fiber Reinforced Polymer.Cov khoom tseem ceeb tshaj plaws uas sib txawv ntawm cov hom fiber ntau yog nruj thiab tensile hom.

Hom Fiber Reinforced Polymer (FRP)
1. iav Fiber Reinforced Polymer (GFRP)
Cov iav fiber ntau yog tsim los ntawm kev sib xyaw silica xuab zeb, limestone, folic acid thiab lwm yam khoom me me.Cov sib tov yog rhuab kom txog thaum nws melts ntawm txog 1260 ° C.
Tom qab ntawd cov iav molten raug tso cai ntws los ntawm qhov zoo hauv platinum phaj.Cov iav strands yog txias, sib sau ua ke thiab mob.Cov fibers yog kos los ua kom muaj zog taw qhia.Tom qab ntawd cov fibers yog woven rau hauv ntau yam ntaub ntawv rau siv nyob rau hauv composites.

Raws li ib qho txhuas cov txiv qaub borosilicate muaj pes tsawg leeg, iav tsim fibers raug suav hais tias yog qhov tseem ceeb ntawm kev txhawb nqa rau polymer matrix composites vim lawv cov khoom siv hluav taws xob siab, tsis tshua muaj kev cuam tshuam rau cov dej noo thiab cov khoom siv tshuab siab.

iav feem ntau yog ib qho kev cuam tshuam zoo fiber ntau tab sis hnyav dua li carbon lossis aramid.Cov iav fibers muaj cov yam ntxwv zoo sib npaug lossis zoo dua li cov hlau hauv qee hom.
