Hauv nroog cua sov, kev siv hluav taws xob nruab nrab ntawm kev thauj mus los, thiab kev siv geothermal, kev rwb thaiv tsev thiab corrosion tsis kam ntawm cov kav dej ncaj qha cuam tshuam rau kev siv hluav taws xob thiab kev ua neej nyob. Nrog rau kev sib sib zog nqus ntawm lub zog-txuag kev kho dua tshiab, ib hom tshiab ntawm cov kav dej sib xyaw ua ke sib sib zog nqus, siab zog, corrosion tsis kam, thiab thermal conductivity tsawg yog maj mam hloov cov khoom siv yeeb nkab thiab ua qhov kev xaiv zoo tshaj plaws rau engineering tej yaam num. Qhov no yog qhovFRP rwb thaiv tsev yeeb nkab-cov yeeb nkab sib xyaw nrog cov iav fiber reinforced yas raws li cov txheej txheem sab hauv thiab sab nrauv thiab muaj kev ua haujlwm siab - txheej rwb thaiv tsev nyob nruab nrab.
Kev tsim kho tshiab
Thaum cov kav hlau ib txwm muaj lub zog siab, lawv tau yooj yim corroded nyob rau hauv cov av noo, kub, los yog acidic / alkaline av ib puag ncig, thiab lawv cov thermal conductivity ua rau kub poob thaum lub sij hawm thauj mus los. Cov ntaub ntawv pov thawj qhia tau hais tias qhov kub poob ntawm cov kav xa hluav taws xob muaj peev xwm qee zaum tshaj 10%, uas ua rau muaj hluav taws xob loj heev. FRP rwb thaiv tsev kav siv ib tug "sandwich" qauv: lub puab fiberglass reinforced yas txheej yog resistant rau media corrosion thiab tsis scale, xyuas kom meej cov kua dej ntws; Cov txheej hauv nruab nrab yog polyurethane lossis phenolic ua npuas ncauj nrog cov thermal conductivity tsawg li 0.03 W / (m·K), txo qhov kub thiab txias; txheej txheej fiberglass txheej ua raws li lub plhaub tiv thaiv, tiv thaiv kev cuam tshuam thiab UV hluav taws xob, tso cai rau kev faus hauv av ncaj qha yam tsis tas yuav tsum muaj cov trench ntxiv.
Qhov kev tsim no tsis tsuas yog daws qhov kev sib tw ob ntawm kev rwb thaiv tsev thiab kev tiv thaiv corrosion, tab sis kuj tseem txo cov yeeb nkab hnyav -tsuas yog 1/4 ntawm cov yeeb nkab steel ntawm tib qhov tshwj xeeb, yog li txo nqi tsheb thauj mus los thiab kev teeb tsa. Qhov tseem ceeb tshaj plaws, nws cov phab ntsa hauv lub du yuav txo tau cov dej tsis kam, tiv thaiv kev tsim cov nplai thaum lub sijhawm ua haujlwm ntev - thiab txuag kwv yees li 15% ntawm lub zog siv.
Daim ntawv thov
Hauv kev tsim kho engineering tam sim no, kev laus thiab corrosion ntawm cov yeeb nkab sib txuas yog qhov tseem ceeb ntawm kev ua haujlwm tsis zoo. FRP rwb thaiv tsev kav, nrog rau lawv cov tshuaj tiv thaiv corrosion, tuaj yeem tiv taus acid, alkali, thiab ntsev yaig hauv av. Txawm tias nyob rau hauv lub sijhawm ua haujlwm ntev -, cov phab ntsa sab hauv tseem du thiab tsis yooj yim ntsuas, yog li ua kom muaj kev thauj mus los tau zoo thiab txo qis kev siv hluav taws xob.
Tsis tas li ntawd, lub Hoobkas- qauv tsim ua ntej yog lwm qhov tseem ceeb ntawm cov khoom no. Vim tias cov txheej txheej rwb thaiv tsev yog ua ntej- molded ntawm lub Hoobkas, tsuas yog kev kho mob sib koom ua ke yuav tsum tau ua thaum lub sijhawm ntawm - qhov chaw teeb tsa, uas tsis tsuas yog ua kom lub voj voog kev tsim kho tab sis kuj zam cov teeb meem zoo cuam tshuam nrog cov tsoos ntawm - site fabrication.
Tam sim no, cov khoom no yog dav siv nyob rau hauv lub nroog centralized cua sov, kub caij nplooj ntoos hlav tsheb thauj mus los, petrochemical, thiab av qhov chaw tshav kub twj tso kua mis systems. Tsis tas li ntawd, vim nws qhov kev tiv thaiv corrosion zoo heev, nws lub neej tsim kev pabcuam tuaj yeem ncav cuag ntau dua 30 xyoo, thiab nws lub neej tag nrho - tus nqi voj voog yog qis dua li cov kav hlau uas xav tau kev saib xyuas tsis tu ncua.
Kev xaiv thiab kev xav txog kev yuav khoom
Rau cov tswv ntawm qhov project, peb yuav tsum tau txiav txim siab thaum xaiv FRP rwb thaiv tsev kav: kev khiav hauj lwm kub, siab ntsuas, thiab rwb thaiv tsev txheej thickness. Cov xov xwm sib txawv yuav tsum muaj cov kab ke sib txuam; Piv txwv li, zoo tib yam epoxy resin yog haum rau kub hauv qab 120 degree, thaum phenolic los yog vinyl ester resins xav tau rau siab - kub. Tsis tas li ntawd, kev kho rwb thaiv tsev ntawm cov pob qij txha yog qhov tseem ceeb rau kev tsim kho; siab -cov ntaub ntawv zoo sib xws tuaj yeem ua kom ntseeg tau tias tag nrho cov kav dej sib txuas tsis muaj cov txuas hniav txias.
Nrog rau kev nce qib ntawm "dual carbon" lub hom phiaj, siab - zog ua haujlwm - txuag cov ntaub ntawv tau txais txiaj ntsig los ntawm txoj cai faib nyiaj. Yog tias koj tab tom npaj rau qhov project tshiab lossis kho dua tshiab, tej zaum koj yuav xav kawm ntxiv txog cov lus qhia tshwj xeeb thiab tus nqi ntawm cov kav dej fiberglass. Peb zoo siab tos txais koj hu rau cov kws tshaj lij kev lag luam rau cov kev daws teeb meem los ua kom koj lub cev muaj zog ntau dua - ua haujlwm tau zoo thiab ruaj khov.
