Kev tshuaj xyuas qhov zoo ntawm basalt fibers rau cov kav dej siab

Basalt fiber ntauComposite high-pressure yeeb nkab, uas muaj cov yam ntxwv ntawm corrosion tsis kam, lub teeb yuag, siab zog, tsis tshua muaj siab rau thauj cov kua thiab lub neej ntev kev pab cuam, yog dav siv nyob rau hauv petrochemical, aviation, kev tsim kho thiab lwm yam teb. Nws cov yam ntxwv tseem ceeb yog: kev tiv thaiv corrosion rau H2S, CO2, dej ntsev, thiab lwm yam, tsis tshua muaj kev tsim kho, tsis tshua muaj siv quav ciab, kev ua haujlwm zoo, ntws coefficient yog 1.5 npaug ntawm cov yeeb nkab steel, thiab tib lub sijhawm, nws muaj lub zog zoo heev, lub teeb yuag, tsis tshua muaj nqi installation, tsim kev pab cuam lub neej ntawm ntau tshaj 30 xyoo, thiab nyob rau hauv tej yaam num, thiab txawm siv 5 xyoo tseem tsis muaj teeb meem. Nws cov ntawv thov tseem ceeb yog: roj av, roj av thiab cov kav dej tshiab; Cov dej phwj tuaj, cov kav dej hauv qab thiab lwm cov kav dej siab siab; petrochemical txheej txheem pipelines; oilfield dej phwj tuaj thiab kev kho dej khib nyiab xa mus kav; hot springs yeeb nkab thiab lwm yam.

Cov txheej txheem tseem ceeb:
Kev sib piv thiab qhov sib txawv ntawmfiberglassthiab basalt fiber ntau cov yeeb nkab:
(1) tib lub ntsiab lus fiber ntau, tib txoj kev pavement, tib yam khoom siv thiab nws cov txheej txheem los xyuas qhov sib txawv ntawm hydrostatic siab ntawm basalt fiber / iav fiber pipeline (DN50PN7, piv txwv li, EP / CBF siab tsis kam ntawm li 30MPa, EP / GF siab tsis kam ntawm txog 25MPa); tib theem ntawm siab, cov basalt fiber ntau txheeb ze rau iav fiber ntau kom txo cov pavement ntawm 10%, 20% los xyuas qhov tseeb theem ntawm hydrostatic siab tsis kam (rau DN50PN7) Piv txwv li, txo 2 txheej EP / CBF siab tsis kam ntawm txog 25MPa).
(2) Kev sim tom kawg tom qab txo txoj kev pavement kom txo tau tag nrho cov khoom siv raw kom txo cov nqi khoom tau raug tswj, qib siab ntawm cov yeeb nkab tseem ua tau raws li qhov yuav tsum tau ua, tus nqi ntawmfiberglass pipelinetxheeb ze tsis muaj qhov nce ntxiv.

Basalt fiber ntau siab yeeb nkab kev ua tau zoo:
(1) zoo heev corrosion kuj
Basalt fiber ntauhigh-pressure pipeline qauv muab faib ua txheej txheej, txheej txheej txheej thiab txheej txheej tiv thaiv ntawm peb ntu. Ntawm lawv, cov txheej hauv ob sab phlu muaj cov ntsiab lus siab resin, feem ntau ntau dua 70%, thiab cov ntsiab lus ntawm nws cov txheej sab hauv resin-nplua nuj txheej yog siab li ntawm 95%. Piv nrog rau cov yeeb nkab steel, muaj ntau yam zoo corrosion kuj, xws li ntau yam muaj zog acids thiab alkalis, ntau yam inorganic ntsev, oxidizing media, hydrogen sulfide, carbon dioxide, ntau yam surfactants, polymer daws, ntau yam organic solvents, thiab lwm yam, tsuav yog xaiv ib tug zoo resin matrix, siab siab pipeline ntawm basalt fiber ntau muaj zog, ntev basalt fibers, thiab lwm yam. HF tsis suav nrog)
(2) Kev qaug zog zoo thiab kev ua haujlwm ntev
Basalt fiber ntau high-pressure pipeline tsim kev pab cuam lub neej yog ntau tshaj 20 xyoo, thiab qhov tseeb, feem ntau tom qab ntau tshaj 30 xyoo ntawm kev siv yog tseem zoo, thiab nyob rau hauv nws cov kev pab cuam lub neej yog tsis muaj txij nkawm.
(3) Kev kub siab-cov kabmob muaj peev xwm
Qhov qub siab ntawmbasalt fiber ntauhigh-pressure pipelines yog 3.5MPa-25MPa (txog 35 MPa, raws li cov phab ntsa thickness thiab suav), piv nrog rau lwm yam uas tsis yog-hlau pipelines, lub siab-resistant muaj peev xwm yog siab dua.
(4) Lub teeb yuag, yooj yim installation thiab kev thauj mus los
Basalt fiber high-pressure yeeb nkab tshwj xeeb lub ntiajteb txawj nqus yog hais txog 1.6, tsuas yog cov yeeb nkab steel lossis cam khwb cia hlau yeeb nkab 1/4 ~ 1/5, daim ntawv thov siv tau qhia tias, nyob rau hauv tib lub siab sab hauv, tib txoj kab uas hla, tib qhov ntev ntawm FRP yeeb nkab, nws qhov hnyav yog li 28% ntawm cov yeeb nkab steel.
(5) siab zog, tsim nyog txhua yam khoom
Basalt fiber ntau cov yeeb nkab axial tensile lub zog ntawm 200 ~ 320MPa, ze rau cov yeeb nkab steel, tab sis ntau tshaj li lub zog ntawm 4 zaug, hauv cov qauv tsim, cov yeeb nkab hnyav tuaj yeem txo qis, kev teeb tsa yooj yim heev.
(6) Lwm yam khoom:
Tsis yooj yim rau nplai thiab siv quav ciab, tsis tshua muaj dej tsis kam, zoo hluav taws xob rwb thaiv tsev, kev sib txuas yooj yim, siab zog, tsis tshua muaj thermal conductivity, tsis tshua muaj thermal stress.
