Lub kaw lus txhawb nqa ua rau muaj kev tswj hwm kev pub thiab kev nruj ntawm cov khoom siv txhawb nqa zoo tshaj plaws. Lub kaw lus rub yog lub luag haujlwm rau rub cov khoom siv txhawb nqa impregnated los ntawm lub pwm tsim, tswj cov qhov ntev thiab cov khoom siv kho tshuab.

Thaum kawg, lub kaw lus kho kom cov resin khov kho los ua cov khoom sib xyaw ua ke kawg. Kev nce qib tsav kev tsim kho tshiab: Kev nqis peev tseem ceeb hauv kev tshawb fawb thiab kev txhim kho tau ua rau muaj kev nce qib tseem ceeb hauv cov khoom siv pultrusion hauv xyoo tas los no. Cov kev tawg tshiab no tau hloov pauv txoj kev pultrusion, txhim kho kev tsim khoom, kev ua haujlwm zoo thiab cov khoom zoo. Nov yog qee qhov kev txhim kho tseem ceeb: Lub kaw lus tswj tsis siv neeg: Cov khoom siv pultrusion niaj hnub no muaj cov tshuab automation tswj hwm los ntawm lub computer uas tuaj yeem tswj tau cov yam ntxwv tseem ceeb xws li kub, resin impregnation thiab kev ntxhov siab. Qib kev ua haujlwm no ua kom muaj kev ua haujlwm zoo sib xws, txo qhov yuam kev ntawm tib neeg thiab ua kom zoo dua kev tsim khoom. Kev Tsim Mould Ntau Yam: Cov qauv pwm txuas ntxiv hloov pauv kom haum rau cov khoom sib txawv thiab qhov nyuaj dua. Cov thev naus laus zis pwm siab heev tuaj yeem tsim cov duab nyuaj, cov duab thiab cov qauv, nthuav dav ntau yam kev siv rau cov khoom sib xyaw pultruded. Cov txheej txheem hloov pauv sai: Kev hloov pauv pwm siv sijhawm ntev tau raug txo qis nrog kev tshwm sim ntawm cov txheej txheem hloov pauv sai hauv cov khoom siv pultrusion. Qhov kev tsim kho tshiab no tso cai rau kev hloov pauv sai ntawm cov qauv khoom sib txawv, txo lub sijhawm tsis ua haujlwm thiab nce kev tsim khoom tag nrho. Lub kaw lus kho kom txuag hluav taws xob: Txhawm rau txhim kho kev ua haujlwm zoo, cov khoom siv pultrusion tam sim no siv lub kaw lus kho kom txuag hluav taws xob. Cov txheej txheem no siv cov khoom siv cua sov zoo heev, kev faib cua sov kom zoo thiab txo kev siv hluav taws xob, ua rau txuag hluav taws xob ntau thiab txo cov nqi.

Cov ntawv thov thiab cov txiaj ntsig: Kev nce qib hauv cov khoom siv pultrusion tau hloov pauv txoj kev tsim khoom ntawm FRP composites thoob plaws ntau yam lag luam: Kev tsim kho thiab kev tsim kho vaj tse: Pultruded composites muaj ntau yam kev siv hauv kev tsim kho thiab kev tsim kho vaj tse. Nws cov khoom sib zog thiab lub zog siab ua rau nws zoo tagnrho rau cov khoom siv xws li beams, kem, gratings thiab rebar. Lub kaw lus kho sai ua kom luv dua cov voj voog tsim khoom, ua rau lub sijhawm tsim kho sai dua. Tsheb thiab Aerospace: Kev lag luam tsheb thiab aerospace tau txais txiaj ntsig los ntawm qhov sib piv zoo ntawm lub zog-rau-qhov hnyav ntawm pultruded composites. Cov ntaub ntawv no txo ​​qhov hnyav, txhim kho kev siv roj thiab ua kom ruaj khov, ua rau muaj kev ua tau zoo dua thiab txo cov nqi txij nkawm. Lub zog rov ua dua tshiab: Cov txheej txheem pultrusion siv rau hauv lub zog cua los tsim cov hniav turbine muaj zog, sib dua thiab tiv taus corrosion. Cov hniav no muab kev ruaj khov zoo dua, tso cai rau kev ntes lub zog siab dua thiab txhim kho kev ua haujlwm ntawm lub zog cua turbine. Marine thiab offshore: Pultruded composites yog cov tshuaj tiv thaiv corrosion heev, ua rau lawv zoo tagnrho rau kev siv marine thiab offshore. Lawv siv rau hauv cov nkoj hulls, offshore platforms, choj Cheebtsam thiab dej hiav txwv corrosion tiv thaiv systems los muab cov kev daws teeb meem pheej yig thiab kav ntev. kev cia siab: Tsav los ntawm kev tshawb fawb thiab kev txhim kho, cov khoom siv pultrusion tau txhim kho tas li. Kev lag luam tab tom tshawb nrhiav cov ntaub ntawv tshiab xws li cov fibers ntuj thiab nanocomposites los txhim kho cov khoom siv kho tshuab thiab kev ruaj khov ntawm cov khoom sib xyaw pultruded.

Ntxiv rau, cov txheej txheem pultrusion tshiab, xws li kev sib txuas ntxiv pultrusion, tab tom raug tsim uas cog lus tias yuav ua rau muaj kev ywj pheej thiab txo lub sijhawm tsim khoom ntxiv. Xaus lus: Kev nce qib sai hauv cov khoom siv pultrusion tau hloov pauv thaj chaw tsim khoom thiab hloov pauv kev tsim cov khoom sib xyaw ua haujlwm siab. Nrog rau cov txheej txheem tswj hwm tsis siv neeg, cov qauv pwm ntau yam, cov txheej txheem hloov pauv sai thiab cov txheej txheem kho kom txuag hluav taws xob, cov khoom siv pultrusion ua rau cov lag luam tsim cov khoom muaj zog dua, sib dua thiab ruaj khov dua. Raws li thev naus laus zis txuas ntxiv mus, cov khoom sib xyaw pultruded yuav tsum ua lub luag haujlwm tseem ceeb hauv kev lag luam xws li kev tsim kho, tsheb, aerospace thiab lub zog rov ua dua tshiab.
