Vim li cas cov khoom fiberglass tag nrho yuav tsum tau tws strand lev?
Hauv kev lag luam fiberglass reinforced yas,chopped strand levyog ib yam khoom tseem ceeb uas tsis tseem ceeb. Txawm hais tias nws yog lub plhaub sab nraud ntawm cov cua turbine hniav, cov khoom sib sib zog nqus ntawm cov khoom siv hauv tsheb, lossis cov khoom siv xws li cov dab da dej thiab cov tais da dej, CSM plays lub luag haujlwm tsis tuaj yeem txhawb kev ua tau zoo, kev ua tau zoo, thiab kev tsim khoom ntawm ntau FRP khoom.
Chopted Ncaj Strand Mat Cov yam ntxwv: Ib qho tseem ceeb hauv kev txiav txim siab FRP kev ua tau zoo
Chopted strand lev yog ib yam uas tsis yog -woven muaj- zoo li cov khoom ua los ntawm chopping thiab dispersing iav fibers. Nws cov txiaj ntsig tseem ceeb nyob hauv peb qhov ntev: wettability, yooj, thiab uniformity. Piv nrog rau cov iav fiber ntau zoo tib yam, cov fibers ntawm CSM yog random thiab tsis yog - faib ncaj qha, tshem tawm tag nrho qhov sib txawv ntawm lub zog ntawm warp thiab weft cov lus qhia, kom ntseeg tau tias tag nrho cov kev ntxhov siab nyob rau hauv FRP cov khoom thiab tiv thaiv cov cheeb tsam tawg.
Los ntawm qhov kev xav ntawm CSM kev ua tau zoo, lub zog tensile yog qhov tseem ceeb: cov ntsiab lus ntawm cov resin ntau dhau ua rau cov khoom siv tawv dhau, kev nyuaj ntawm kev tsim kho, thiab pov tseg ntawm resin thiab lwm yam khoom siv; resin cov ntsiab lus tsis txaus ua rau xoob iav fibers, cuam tshuam cov khoom muaj zog. Emulsion-raws li tws strand lev, vim nws cov khoom ntawm nws cov emulsion binder, muaj kev hloov tau zoo heev rau tes nteg- txheej txheem. Nws yog ib qho yooj yim rau cov neeg ua haujlwm sib kis thiab txiav, thiab tsim cov plua plav fiberglass tsawg, ua rau nws yog ib qho kev xaiv rau me me - mus rau nruab nrab -batch ntau lawm thiab cov khoom siv.
Core Applications: Cov ntaub ntawv tseem ceeb uas npog ntau qhov chaw
1. Cov neeg nqa khoom tseem ceeb rau tes nteg- cov txheej txheem nce: Qhov no yog qhov chaw siv dav tshaj plaws rau cov khoom siv strand. Tes nteg-up relies on manual layering and resin impregnation. Cov kev ntxhib los mos ntawm tws strand lev yooj yim ua raws li qhov chaw nkhaus, ua kom muaj kev sib haum xeeb rau cov chav da dej thiab cov khoom siv kho kom haum, ua kom cov khoom flatness.
2. Cov khoom siv sib zog ua kom muaj zog: Hauv cov khoom siv hauv tsheb, cov khoom siv cua turbine, thiab lwm yam kev lag luam, chopped strand lev hloov qee cov ntaub ntawv tuab, txo cov khoom hnyav thaum tuav lub zog tensile thiab flexural txaus, ua tau raws li qhov xav tau ntawm cov khoom siv hnyav tsis tau siab - cov khoom muaj zog.
3. Corrosion thiab hnav- tiv thaiv txheej tiv thaiv: Thaum cov khoom siv fiberglass siv rau hauv cov tshuaj thiab corrosion- tiv thaiv ib puag ncig, chopped strand lev tuaj yeem ua ke nrog cov resin los tsim cov txheej tiv thaiv ntom ntom, uas thaiv kev nkag mus ntawm cov kua qaub, alkalis thiab dej vapor, thiab txuas ntxiv lub neej kev pab cuam ntawm cov khoom. Qhov no yog ib qho laj thawj tseem ceeb vim li cas lwm cov khoom siv txhawb zog yog qhov nyuaj los hloov.
