Cov yeeb nkab basalt fiber composite siab siab, uas muaj cov yam ntxwv ntawm kev tiv thaiv corrosion, lub teeb yuag, lub zog siab, tsis tshua muaj kev tiv thaiv rau kev xa cov kua thiab lub neej ntev, yog siv dav hauv petrochemical, aviation, kev tsim kho thiab lwm yam teb. Nws cov yam ntxwv tseem ceeb yog: tiv thaiv kev xeb ntawm H2S, CO2, brine, thiab lwm yam, tsis tshua muaj kev sib sau ua ke, tsis tshua muaj waxing, kev ua haujlwm zoo, cov coefficient ntws yog 1.5 npaug ntawm cov yeeb nkab hlau, thaum muaj lub zog zoo heev, lub teeb yuag, tus nqi teeb tsa qis, lub neej tsim ntau dua 30 xyoo, hauv qee qhov project, txawm tias siv 50 xyoo tseem tsis muaj teeb meem. Nws cov ntawv thov tseem ceeb yog: roj av nyoos, roj av thiab cov kav dej xa dej tshiab; cov kav dej siab xws li kev txhaj tshuaj dej phwj thiab cov kav dej roj downhole; cov kav dej txheej txheem petrochemical; cov kav dej phwj thiab kev kho dej khib nyiab hauv roj av; cov kav dej spa, thiab lwm yam.

Kev ua tau zoo ntawm cov kav dej basalt fiber high-pressure:
(1) Kev tiv thaiv xeb zoo heev
Cov qauv ntawm cov kav dej basalt fiber siab siab tau muab faib ua peb ntu: txheej sab hauv, txheej txheem thiab txheej tiv thaiv sab nraud. Ntawm lawv, cov ntsiab lus resin ntawm txheej sab hauv siab, feem ntau siab dua 70%, thiab cov ntsiab lus resin ntawm txheej nplua nuj resin ntawm nws sab hauv yog siab txog li 95%. Piv nrog cov kav hlau, nws muaj kev tiv thaiv corrosion zoo dua, xws li cov kua qaub thiab alkali muaj zog, ntau yam kev daws teeb meem inorganic ntsev, oxidation media, hydrogen sulfide, carbon dioxide, ntau yam surfactants, polymer kev daws teeb meem, ntau yam organic solvents, thiab lwm yam. Tsuav yog cov resin matrix raug xaiv zoo, cov kav dej basalt fiber siab siab tuaj yeem tiv taus lub sijhawm ntev (tshwj tsis yog cov kua qaub concentrated, alkali muaj zog thiab HF)
(2) Kev ua haujlwm qaug zog zoo thiab lub neej ntev
Lub neej tsim ntawm cov yeeb nkab basalt fiber siab yog ntau tshaj 20 xyoo, thiab qhov tseeb, nws feem ntau tsis muaj teeb meem tom qab ntau tshaj 30 xyoo ntawm kev siv, thiab tsis tas yuav saib xyuas thaum lub sijhawm ua haujlwm.
(3) Muaj peev xwm siab siab
Qhov siab ib txwm ntawm cov yeeb nkab basalt fiber siab yog 3.5 MPa-25 MPa (txog li 35 MPa, nyob ntawm phab ntsa tuab thiab suav), uas muaj kev tiv taus siab dua piv rau lwm cov yeeb nkab uas tsis yog hlau.
(4) Lub teeb yuag, yooj yim rau nruab thiab thauj
Qhov hnyav tshwj xeeb ntawm Xuan Yan fiber siab-siab yeeb nkab yog li 1.6, uas tsuas yog 1/4 txog 1/5 ntawm cov yeeb nkab hlau lossis cov yeeb nkab hlau cam khwb cia, thiab daim ntawv thov tiag tiag qhia tau hais tias nyob rau hauv lub hauv paus ntawm tib lub siab sab hauv, qhov hnyav ntawm FRP yeeb nkab ntawm tib lub cheeb thiab ntev yog li 28% ntawm cov yeeb nkab hlau.
(5) Lub zog siab thiab cov khoom siv kho tshuab tsim nyog
Basalt fiber yeeb nkab siab siab muaj zog axial tensile zog ntawm 200-320MPa, ze rau cov yeeb nkab hlau, tab sis lub zog yog li 4 npaug ntau dua. Hauv kev tsim qauv, qhov hnyav ntawm cov yeeb nkab tuaj yeem txo qis heev, kev teeb tsa yooj yim heev.
(6) Lwm yam khoom:
Tsis yooj yim rau nplai thiab quav ciab, tsis kam me me, zoo hluav taws xob rwb thaiv tsev, yooj yim txuas, muaj zog siab, thermal conductivity tsawg, tsis tshua muaj thermal stress.
