FRP Composite Tsheb Lub Cev Vaj Huam Sib Luag

A: Ib qho FRP (Fiberglass Reinforced Plastic / Fiber Reinforced Polymer) cov tsheb sib xyaw ua ke lub cev yog lub siab - lub zog, lub teeb yuag sandwich vaj huam sib luag tau tsim tshwj xeeb rau cov tsheb thauj khoom, cov tsheb thauj khoom, cov tsheb thauj khoom qhuav, tsheb thauj khoom (refrigerated) tsheb, motorhome / RV lub cev, thiab kev tsim kho tsheb tshwj xeeb. Lub vaj huam sib luag muaj xws li: (1) ob daim tawv FRP - siab -lub zog iav-fiber- reinforced polyester los yog epoxy composite ntsib (feem ntau 1.0–2.5mm tuab ib sab) muab ib tug du, cuam tshuam -resistant, weatherproof nto; (2) lub teeb yuag insulating core - XPS (Extruded Polystyrene, kaw- cell foam) los yog nruj PU (Polyurethane, kaw- cell foam), feem ntau 15-100mm tuab, muab lub vaj huam sib luag thickness, thermal rwb thaiv tsev, thiab cov qauv shear zog. Tag nrho cov kev sib dhos yog sib koom ua ke nyob rau hauv kev kub siab hauv xovxwm kub, tsim ib qho kev sib xyaw monolithic uas sib txuas cov puncture resistance thiab weatherproof durability ntawm FRP nrog lub ultralight yuag thiab thermal rwb thaiv tsev ntawm cov tub ntxhais ua npuas ncauj. Qhov no yog qhov tseem ceeb ntawm vaj huam sib luag thev naus laus zis hauv kev lag luam niaj hnub tsheb lub cev tsim khoom, hloov cov khoom siv ib txwm siv (steel sheet, aluminium ntawv, plywood) vim nws lub zog zoo tshaj - rau - qhov hnyav piv, thermal kev ua tau zoo, corrosion resistance, thiab txij nkawm- dawb lifespan.

A: Piv rau steel ntawv lub cev panels:
① Qhov hnyav txo: FRP composite panels txo lub cev hnyav los ntawm 50-70% vs. steel lub cev siv. Lub 13.6m qhuav van trailer lub cev siv FRP/XPS panels txuag 800–1,500 kg vs. steel - ncaj qha nce payload muaj peev xwm thiab txo cov roj noj los ntawm 5–10%.
② Corrosion kuj: FRP yuav tsis xeb. Steel lub cev nyob rau hauv av ntub, ntug hiav txwv dej, los yog lub caij ntuj no (txoj kev- ntsev) tej yam kev mob yuav tsum tau ib txwm los tiv thaiv- kev kho corrosion thiab tseem deteriorate tshaj 5-8 xyoo. FRP lub cev tswj kev ncaj ncees rau 15–20+ xyoo.
③ Thermal rwb thaiv tsev: ua npuas ncauj core panels muab cov rwb thaiv tsev hauv paus (R-tus nqi 3–5 ib 25mm). Steel lub cev muaj xoom rwb thaiv tsev; insulating ib lub cev steel yuav tsum tau ntxiv ib txheej rwb thaiv tsev cais, ntxiv hnyav thiab complexity.
④ Smooth seamless nto: FRP gelcoat muab ib tug du, glossy tag uas yog ib qho yooj yim los ntxuav, tsis ntxiab av, thiab nthuav tawm ib tug hwm hom duab. Tsis muaj rivets, seams, lossis welds pom ntawm sab nrauv.
⑤ Kev cuam tshuam thiab cov hniav tsis kam: FRP panels flex nyob rau hauv kev cuam tshuam thiab rov qab lawv cov duab; steel dents mus tas li. Kev sib tsoo me me uas yuav tsum tau hloov cov vaj huam sib luag steel feem ntau yog cov tshuaj pleev ib ce - tsuas yog ntawm FRP.
⑥ Cov nqi tsim khoom qis dua: FRP lub cev sib dhos yog yooj yim dua thiab nrawm dua li kev siv lub cev steel (tsawg vuam, kev ua haujlwm tsawg dua, cov khoom tsawg dua). Tag nrho cov nqi tsim khoom feem ntau yog 15-25% qis dua.
⑦ Cov duab zoo dua thiab cov khoom lag luam: FRP muab cov khoom siv zoo tshaj plaws rau cov ntaub qhwv lub tsheb, decals, thiab xim piv rau corrugated lossis riveted steel.
⑧ Tsis muaj condensation: cov tub ntxhais ua npuas ncauj + FRP daim tawv nqaij tshem tawm cov teeb meem condensation (hws) ntawm ib leeg - cov tawv nqaij hlau, tiv thaiv cov khoom thauj los ntawm kev puas tsuaj ntawm cov dej noo.
Piv rau aluminium ntawv lub cev panels:
① Tus nqi qis: FRP / XPS panels yog 20-30% tsawg nqi ib m² vs. aluminium honeycomb lossis aluminium ntawv
② Zoo dua thermal rwb thaiv tsev: aluminium yog thermal conductor; FRP ua npuas ncauj core muab rwb thaiv tsev yam tsis muaj txheej ntxiv
③ Tsis muaj galvanic corrosion: txhuas nyob rau hauv kev sib cuag nrog steel chassis Cheebtsam yuav tsum tau cais; FRP yog hluav taws xob tsis yog - conductive
④ Kev kho yooj yim dua: FRP tuaj yeem kho thiab kho ntawm -site; aluminium xav tau tshwj xeeb vuam
