1. Lub teeb yuag thiab lub zog siab
Qhov ntom ntawm FRP profile yog li 1.7, uas yog 4 ~ 5 npaug sib zog dua li cov hlau, tab sis nws lub zog loj heev. Nws lub zog tensile yog 350 ~ 450MPa, uas yog ze rau cov pa roj carbon zoo tib yam. Lub zog khoov yog 388mpa thiab khoov modulus ntawm elasticity yog 20900mpa. Yog li ntawd, steel hauv ob sab phlu tsis tas yuav tsum tau muaj zog ntxiv. Tom qab kev sim, cov cua siab tsis kam ntawm FRP qhov rais tuaj yeem ncav cuag 5.3kpa, uas siab tshaj qib ntawm Qib 8 hauv thoob ntiaj teb gb/t7106-2002 tus qauv.
2. Kev txuag hluav taws xob thiab thermal rwb thaiv tsev
Lub thermal conductivity ntawm FRP profile yog 0.39w/m · K, uas tsuas yog 1/100 ~ 1/1000 ntawm hlau. Nws yog cov khoom siv thermal rwb thaiv tsev zoo heev. Tsis tas li ntawd, FRP profile yog qhov qhib lub vev xaib, thiab txhua qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob Los ntawm kev tshuaj xyuas, qhov kub hloov pauv coefficient ntawm FRP casement qhov rais (ib lub thav duab ob lub iav qhov rais) k0=2.2w/ (M2 · K), uas yog qib 8 hauv lub teb chaws tus qauv gb/t8484-2002 ; Lub tshav kub hloov coefficient ntawm FRP casement qhov rais (ib lub thav duab peb iav qhov rais) k0=1.8w/ (M2 · K), uas belongs rau qib 9 hauv lub teb chaws tus qauv gb/t8484-2002; Lub tshav kub hloov coefficient ntawm iav fiber reinforced yas casement qhov rais (ib thav duab peb lub qhov rais iav, tsis tshua muaj hluav taws xob iav) k0=1.3w/ (M2 · K), uas belongs rau qib 10 hauv lub teb chaws tus qauv gb/t{ {20}}.
3. Kev ua haujlwm zoo sealing
Thaum lub sij hawm sib dhos txheej txheem ntawm FRP qhov rooj thiab qhov rais, lub kaum sab xis kho txais cov txheej txheem nplaum thiab ntsia hlau txuas. Nyob rau tib lub sijhawm, txhua qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob. Tsis tas li ntawd, cov qauv tshwj xeeb profile muaj kev sib khi zoo. Nws tau raug sim los ntawm lub teb chaws kev tsim kho engineering zoo saib xyuas thiab tshuaj xyuas qhov chaw, Beijing kev tsim kho khoom vaj khoom tsev cov khoom lag luam zoo saib xyuas thiab chaw soj ntsuam thiab Beijing kev tsim kho engineering zoo tshuaj xyuas qhov chaw raws li, thiab huab cua nruj tau mus txog qib 5 hauv lub teb chaws tus qauv gb. /t7107-2002; Cov dej nruj yuav tsum ncav cuag qib 3 hauv lub teb chaws tus qauv gb/t7107-2002.
4. Kev noj qab haus huv, kev tiv thaiv ib puag ncig ntsuab thiab kev txuag hluav taws xob zoo kawg nkaus
Cov txiaj ntsig ntawm FRP qhov rooj thiab qhov rais profiles ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hauv tsev loj hauv GB {{0}}} txwv ntawm radionuclides hauv cov khoom siv hauv tsev. Cov txiaj ntsig kev xeem yog 0.2, qhov ntsuas pom sab hauv yog 0.2, thiab qhov ntsuas sab nraud yog 0.2.
5. Zoo suab rwb thaiv tsev nyhuv
Raws li kev ntsuam xyuas ntawm lub teb chaws kev tsim kho engineering zoo saib xyuas thiab chaw soj ntsuam, qhov hnyav lub suab rwb thaiv tsev RW ntawm hom FRP ob lub iav thiab peb lub iav qhov rais cua acoustic meter ncav cuag 36dB thiab 39db raws li, thiab lub suab rwb thaiv tsev kev ua tau zoo yog qib 4.
6. corrosion kuj
FRP yog cov khoom zoo heev corrosion-resistant. Nws muaj kev tiv thaiv zoo rau cov kua qaub, alkali, ntsev thiab feem ntau cov organic tshuaj, dej hiav txwv thiab av noo, thiab kuj muaj kev tiv thaiv rau kev ua ntawm cov kab mob. Cov yam ntxwv no tshwj xeeb tshaj yog siv rau hauv cov nag, av noo thiab ntug hiav txwv dej, nrog rau cov chaw uas muaj corrosive media.
7. Kev ruaj ntseg zoo
Lub linear expansion coefficient ntawm FRP profile yog 7.3 × 10-6 / degree, qis dua steel thiab aluminium alloy, 1/15 ntawm yas. Yog li ntawd, qhov loj ntawm kev ruaj ntseg ntawm FRP lub qhov rooj thiab qhov rais yog qhov zoo, thiab qhov kev hloov ntawm qhov kub thiab txias yuav tsis cuam tshuam qhov kev hloov pauv ntawm lub qhov rooj thiab qhov rais.
