xov xwm

Basalt fiber roving (feem ntau yog hais txog untwisted roving) yog ib qho ntawm cov khoom siv tseem ceeb siv rau hauv kev tsim cov basalt fiber composite reinforcement (tom qab no hu ua basalt composite reinforcement). Raws li cov ntaub ntawv tshiab tshaj plaws rau pej xeem, nws cov ntawv thov, cov txheej txheem tsim khoom, thiab cov txiaj ntsig kev ua tau zoo yog raws li nram no:

Kev Txhais thiab Kev Siv ntawmBasalt Composite Reinforcement

Kev txhawb nqa basalt fiber composite yog ib hom kev txhawb nqa uas tsis yog hlau uas tsim los ntawm kev siv basalt fiber ua cov khoom siv txhawb nqa thiab cov resin (xws li epoxy resin lossis unsaturated polyester) ua lub matrix, los ntawm cov txheej txheem xws li pultrusion, winding, lossis curing.

Nws yog siv rau hauv kev tsim kho vaj tse los hloov cov hlau txhawb nqa ib txwm muaj, xws li hauv kev txhawb nqa cov qauv pob zeb, cov choj, txoj kev, thiab kev tsim kho hauv dej hiav txwv, muab cov txiaj ntsig suav nrog kev tiv thaiv corrosion, lub teeb yuag, lub zog siab, cov khoom tsis muaj hlau nplaum, thiab kev rwb thaiv hluav taws xob.

Lub Luag Haujlwm ntawm Basalt Fiber Roving hauv Composite Reinforcement

Kev Txhawb Nqa: Kev roving tsis sib ntswg muaj ntau cov filaments sib luag ua ke, muab kev sib zog sib npaug. Nws yog qhov tsim nyog rau kev tsim cov txheej txheem xws li pultrusion thiab winding, ua kom zoo dua lub zog tensile thiab elastic modulus ntawm cov khoom sib xyaw ua ke.

Kev Sib Tw Txheej Txheem: Raws li tus qauv hauv tebchaws GB / T 25045-2025, cov kab rov tav tsis sib txuas (haum rau cov txheej txheem xws li pultrusion thiab winding) yuav tsum muaj lub zog tawg ntawm ≥ 0.45 N / tex thiab lub zog tensile ntawm ≥ 2500 MPa tom qab resin impregnation, yog li ua tau raws li qhov xav tau siab ntawm kev txhawb nqa composite.

Kev Kho Mob Nto: Txhawm rau txhim kho kev sib txuas ntawm cov tshuaj resin, kev roving feem ntau yog kho nrog tus neeg sawv cev kho qhov chaw (xws li tus neeg sawv cev txuas) ua ntej cov tshuaj impregnation.

Cov Txheej Txheem Npaj Ib Txwm Muaj

• Kev Npaj Fiber: Xaiv cov qauv uas ua raws li tus qauvbasalt fiber roving(ib txoj kab uas hla ntawm cov fiber feem ntau yog 7–13 μm).
• Kev Kho Mob Nto: Txheej lossis impregnate nrog tus neeg sawv cev tshwj xeeb los txhim kho kev sib txuas ntawm cov fiber-resin.
• Resin Impregnation: Dhau qhov roving los ntawm lub dab dej resin kom nws puv nrog thermosetting resin (xws li epoxy lossis vinyl ester).
• Kev Moulding thiab Curing: Pub cov roving rau hauv lub pultrusion tuag thiab kho nws hauv qab cua sov kom tsim tau ib qho stiffener nrog cov duab cross-sectional xav tau.
• Kev Ua Tom Qab: Txiav, tshuaj xyuas, thiab ntim cov khoom siv los tsim cov khoom sib xyaw ua tiav.
