Kev nthuav dav cua sov ntawm cov khoom siv hluav taws xob nruab hnub nrig cuam tshuam ncaj qha cuam tshuam rau kev nyuaj ntawm kev tsim kho, kev tsim kho tus nqi, thiab kev xav txog kev ua haujlwm tsis muaj dej tom qab ua tiav txoj haujlwm. Yog li ntawd, hauv lub ru tsev nrog cov khoom siv coiled thiab cov xim tha xim, kev nthuav dav cua sov ntawm cov khoom siv teeb pom kev zoo yog qhov tseem ceeb tshaj plaws uas yuav tsum tau txiav txim siab hauv kev tsim thiab tsim kho. Cov cua sov nthuav dav ntawm FRP daim ntawv nruab hnub nrig yog 2.6 × 10-5cm/cm/℃ thiab cov cua sov nthuav dav coefficient ntawm cov xim hlau ntawv zoo ib yam, qhov kev txav chaw txheeb ze tshwm sim los ntawm kev hloov pauv txias thiab cua sov tsawg dua, thiab nws tsis yooj yim xau dej vim deformation. Qhov ntsuas cua sov nthuav dav ntawm PC lub hnub ci vaj huam sib luag yog 6.75 × 10-5cm/cm/℃, uas yog kwv yees li 5 npaug ntawm cov xim hlau. Qhov sib txawv ntawm qhov kub ntawm cov xim hlau ntawv ru tsev sib txawv heev. Qhov kev txav chaw txheeb ze ntawm daim ntawv PC tshwm sim los ntawm kev nthuav dav cua sov thiab kev cog lus loj dhau, ua rau muaj kev sib cuag xoob lossis ntuag lossis deformed ntsia hlau qhov thiab dej tawm. (Cov cua sov nthuav dav coefficient ntawm cov xim hlau ntawv yog 1.25 × 10-5cm/cm/℃)
2. Kev sib koom ua ke FRP nruab hnub nrig tuaj yeem hloov kho raws li xav tau kom ua tiav cov ntu ntawm cov xim xim hlau, thiab tus nqi qis, yooj yim thiab nrawm, thiab kev hloov kho lub sijhawm tsuas yog xav tau 2 hnub. PC daim ntawv feem ntau yog lub vaj huam sib luag tiaj tiaj, nrog ob peb ntu xaiv los ntawm, uas tsis tuaj yeem phim lub ru tsev xim hlau zoo heev, thiab kev kho kom haum yog kim thiab siv sijhawm.
3. Tus nqi tsim kho thiab dej tsis qab. Vim tias FRP daim ntawv teeb pom kev tuaj yeem hloov kho kom haum raws ntu ntu raws li qhov xav tau, tsuas yog me me ntawm tus kheej tapping ntsia hlau thiab daim kab xev silicone xav tau rau kev teeb tsa, yog li kev teeb tsa tau yooj yim, nrawm, tus nqi qis, thiab zoo. dej tsis qab. Vim yog daim ntawv PC Nws yog ua los ntawm cov ntawv tiaj. Txhawm rau kom sib tshooj nrog cov xim hlau los xij, yuav tsum muaj lwm cov txheej txheem pabcuam. Cov ntawv hlau xim ntawm lub ru tsev yog cov duab yoj, uas ua rau cov pob qij txha nyuaj rau tuav. Tus nqi tsim kho yog siab, siv sijhawm thiab siv zog. Qhov siab tshaj plaws tuaj yeem tsuas yog 6 meters. Yog li ntawd, cov pob qij txha yuav tsum tau kho nrog aluminium blanking, thiab cov sub-purlins yuav tsum tau ntxiv rau ntawm cov khoom, uas ua rau kev tsim kho tus nqi thiab nyuaj. Tsis tas li ntawd, vim yog qhov ua kom sov siab nthuav dav coefficient, kev nthuav dav ua ntej nthuav dav yuav tsum tau muab xam thaum tsim kho. Khaws. Yog li nws yog qhov yooj yim heev ua rau cov dej ntws tawm.
4. Lub teeb pom kev zoo ntawm lub teeb-kis FRP daim ntawv nruab hnub nrig yog 0-85%. Vim tias qee qhov kev faib ua feem ntawm cov iav fiber ntau thiab cov iav tsis muaj qhov rooj iav tau ntxiv rau polyester, lub teeb yuav tawg tawg thaum nws hla mus, thiab nws yuav tsis tso rau hauv av. Txoj siv tawv yuav tsis tsim qhov ci thiab tuaj yeem muab chaw ua haujlwm zoo. Lub PC ntawv yog ua los ntawm cov ntshiab cob nrog lub teeb pom kev zoo ntawm 0-88%. Thaum lub teeb dhau los ntawm nws, nws yuav tsis tawg thoob plaws, tab sis yuav rov ua dua. Lub teeb yuav tso lub teeb pom kev meej rau hauv av. Thaum tib neeg saib, lawv zoo siab heev thiab ua rau pom kev, thiab lawv tsis xis nyob thaum ua haujlwm.
5. Kev pab lub neej FRP nruab hnub nrig daim ntawv npog nrog 20-micron DuPont Melinex 301 tiv thaiv zaj duab xis ultraviolet, uas tuaj yeem txiav ntau dua 99% ntawm ultraviolet rays thiab tiv taus lwm yam corrosives, tiv thaiv cov substrate los ntawm kev puas tsuaj, thiab ua daim ntawv nruab hnub nrig siv Lub neej luv tuaj yeem ncav cuag tsawg kawg 15 xyoos, tab sis tuaj yeem ncav cuag ntau dua 20 xyoo. PC lub hnub ci daim ntawv siv cov tshuaj tiv thaiv ultraviolet ntxiv rau hauv cov tshuaj los tiv thaiv ultraviolet rays, tab sis tib lub sijhawm, kev ua kom huv ntawm cov ntaub ntawv raw tau txo qis thiab daim ntawv ua haujlwm raug cuam tshuam, yog li kev tiv thaiv ultraviolet tsis tuaj yeem ua haujlwm tau zoo rau ntev, thiab nws yog hnub nyoog yooj yim, tig daj thiab ua nkig.
6. Kev kho qhov chaw Nto ntawm FRP daim ntawv teeb pom kev zoo tau npog nrog lub npe 20 micron polymer zaj duab xis, uas tsis nqa hluav taws xob zoo li qub, tsis nqus plua plav, thiab tuaj yeem ntxuav nrog dej lossis nag. Nws yog ib qho yooj yim los ntxuav, ua kom pom kev zoo thiab huv si rau lub sijhawm ntev, tus nqi kho qis, thiab lub voj voog ntev. Vim yog cov yam ntxwv electrostatic adsorption ntawm PC lub hnub ci vaj huam sib luag, nws feem ntau nqus cov hmoov av hauv huab cua, uas yuav cuam tshuam rau kev sib kis thiab kev zoo nkauj tom qab lub sijhawm ntev. Cov vaj huam sib luag hauv PC muaj qhov ua tsis zoo rau cov kua qaub thiab alkali thiab tsis tuaj yeem ntxuav nrog cov tshuaj ntxhua khaub ncaws. Dej huv Tsis tas li, cov hmoov av electrostatically adsorbed tsis tuaj yeem ntxuav, thiab tus nqi saib xyuas siab.
7. Tear tsis kam thiab lub zog tensile FRP lees txais cov qauv txheej txheem ntawm sab saud thiab qis dua thiab iav fiber ntau ntxiv, yog li nws muaj qhov tsim kua muag zoo thiab lub zog tensile. Lub zog tensile yog 75. Qhov tshwj xeeb ntawm cov qauv txheej txheem ntawm cov ntawv hauv PC ua rau cov neeg pluag tsis kam thiab lub zog tensile, thiab nws yog qhov yooj yim kom raug khawb los ntawm cov hlau burrs thiab cov dej xau, thiab ib puag ncig ntawm cov ntsia hlau qhov kuj yooj yim rau raug dua Lub zog tensile yog 63.
8. Thauj khoom ua tau zoo FRP daim ntawv nruab hnub nrig muaj qhov ua tau zoo, tab sis kev nruj thiab tsis yooj yim khoov. Lub zog khoov yog 125. PC lub hnub ci daim ntawv muaj qhov nruab nrab rigidity, tab sis zoo heev toughness, zoo heev kev thauj mus los thiab tuav kev ua tau zoo; nws tuaj yeem khoov rau hauv ntau yam arcs ntawm qhov xav tau. Lub zog khoov yog 96.
