Cov txheej txheem pultrusion molding yog extrude cov iav fiber txuas ntxiv impregnated nrog resin kua nplaum thiab lwm yam khoom siv txuas ntxiv xws li daim kab xev iav, polyester nto felt, thiab lwm yam. Ib txoj kev rau kev tsim cov iav fiber reinforced yas profiles los ntawm kev kub kho hauv lub cub tawg curing. Kuj hu ua cov txheej txheem pultrusion txuas ntxiv. Cov kav dej tseem ceeb tsim khoom, rods, profiles, phaj thiab lwm yam iav fiber reinforced yas.
Qhov zoo ntawm cov txheej txheem pultrusion molding yog: cov khoom siv yooj yim, tus nqi qis, kev tsim khoom siab, yooj yim los tsim cov kab ntau lawm tsis siv neeg, thiab cov khoom ruaj khov zoo; tuaj yeem ua si tag nrho rau lub luag haujlwm ntawm cov ntaub ntawv txhawb nqa, cov khoom siv kho tshuab siab, tshwj xeeb tshaj yog lub zog ntev thiab modulus; kev siv cov khoom siv raw zoo, tus nqi siab, tsis muaj kev pov tseg ces kaum; lub zog ntev thiab transverse ntawm qhov profile tuaj yeem hloov kho kom haum rau ntau yam kev siv; nws qhov ntev tuaj yeem txiav raws li qhov xav tau.
Cov resins siv dav hauv cov khoom pultruded yog unsaturated polyester resins, ua raws li epoxy resins, uas feem ntau yog siv rau cov khoom uas muaj cov khoom siv kho tshuab siab thiab cov cua sov tsis kam, ntxiv rau vinyl ester resins, phenolic resins, thermoplastic resins, thiab lwm yam. Cov kev cai ntawm pultrusion molding txheej txheem rau cov kua nplaum resin yog: viscosity qis, yooj yim nkag mus rau hauv cov khoom siv reinforcing; lub sijhawm ntev gel (feem ntau yuav tsum siv ntau dua 8 teev), kho sai, kom ua tau raws li qhov yuav tsum tau ua ntawm kev molding tas mus li; kev nplaum zoo, Lub shrinkage kho yog me me; qhov yooj ywm zoo, thiab cov khoom tsis yooj yim tawg.
Daim ntawv thov ntawm epoxy resin composite pultrusion profile
Cov khoom siv epoxy resin composite pultrusion feem ntau yog siv rau:
1) Lub teb hluav taws xob tam sim no yog qhov chaw siv dav tshaj plaws thiab yog ib qho ntawm cov chaw tseem ceeb ntawm kev txhim kho. Xws li cov pas nrig tso pa tawm ntawm lub tshuab hloov pauv cua, cov pas nrig insulator siab, cov raj tiv thaiv cable siab, cov khib cable, cov ntaiv insulating, cov pas nrig insulating, ncej, cov neeg tiv thaiv kev taug qab, cov khib faib cable, cov khoom siv lub cev muaj zog, thiab lwm yam.
2) Kev lag luam tshuaj tiv thaiv xeb yog qhov kev lag luam loj hlob sai tshaj plaws hauv xyoo tas los no. Cov khoom lag luam ib txwm muaj xws li: cov qauv txhawb nqa yeeb nkab, cov pas nrig nqus dej, cov kav dej siab hauv qhov, cov khoom siv kho dej khib nyiab, cov baffles tshuaj lom neeg, cov ntaiv, cov tes tuav platform, cov plag tsev grille, thiab lwm yam hauv tshuaj lom neeg, roj av, ntawv, metallurgy thiab lwm yam chaw tsim khoom.
3) Hauv kev tsim kho vaj tse, nws feem ntau yog siv rau cov qauv teeb, cov qauv siab lossis cov qauv tshwj xeeb. Xws li cov qauv chav txav tau, cov ntaub ntawv rau cov qauv qhov rooj thiab qhov rai, trusses, cov choj teeb, railings, cov tsev pheeb suab, cov qauv qab nthab, cov qauv boron loj, thiab lwm yam.
4), kev ua si thiab kev lom zem xws li cov pas nrig nuv ntses, cov pas hockey, snowboards, ncej vaults, hneev thiab xub, thiab lwm yam.
5) Cov chaw thauj mus los xws li cov chaw nres tsheb, cov thav tsheb thauj khoom, cov tsheb thauj khoom txias, cov chaw caij tsheb, cov chaw thauj khoom, cov khoom siv bumpers, decks, cov neeg tiv thaiv txoj kev tsheb ciav hlau hluav taws xob, thiab lwm yam.
6) Hauv thaj chaw muaj zog, nws feem ntau yog siv rau cov khoom siv hnub ci, cov hniav cua turbine, thiab cov kav dej roj.
7) Hauv thaj chaw aerospace, xws li cov kav dej rwb thaiv tsev rau dav hlau thiab spacecraft, cov khoom siv lub cev muaj zog rau spacecraft, cov dav hlau sib xyaw I-beams, cov kab trough thiab cov kab plaub fab, cov pas nrig khi dav hlau, cov pas nrig txuas, thiab lwm yam.
