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

Cov fiber basaltCov yeeb nkab sib xyaw ua ke muaj cov yam ntxwv ntawm kev tiv taus corrosion, lub teeb yuag, lub zog siab, tsis tshua muaj kev tiv taus kev thauj 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: kev tiv taus corrosion rau H2S, CO2, dej ntsev, thiab lwm yam, tsis tshua muaj qhov sib sau ua ke, tsis tshua muaj quav ciab, kev ua haujlwm zoo, cov coefficient ntws yog 1.5 npaug ntawm cov yeeb nkab hlau, thiab tib lub sijhawm, nws muaj lub zog zoo heev, lub teeb yuag, tus nqi teeb tsa qis, lub neej tsim qauv ntau dua 30 xyoo, thiab hauv qee qhov project, thiab txawm tias siv tau 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; kev txhaj tshuaj dej phwj tuaj, cov kav dej roj downhole thiab lwm yam kav dej siab; cov kav dej ua haujlwm petrochemical; cov kav dej xa dej phwj tuaj thiab cov kav dej kho dej khib nyiab hauv av; cov kav dej kub thiab lwm yam.

Cov Txheej Txheem Tseem Ceeb:
Kev sib piv thiab qhov sib txawv ntawmfiberglassthiab basalt fiber siab siab yeeb nkab:
(1) cov fiber ntau yam, tib txoj kev, tib cov khoom siv thiab nws cov txheej txheem los xyuas qhov sib txawv ntawm qhov siab hydrostatic ntawm basalt fiber / iav fiber pipeline (DN50PN7, piv txwv li, EP / CBF siab tsis kam ntawm txog 30MPa, EP / GF siab tsis kam ntawm txog 25MPa); tib theem ntawm siab, cov fiber basalt piv rau cov iav fiber kom txo qhov kev taug kev 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) Qhov kev sim tom qab txo txoj kev pavement kom txo tau tag nrho cov khoom siv raw kom txo cov nqi khoom tau raug tswj, qib ntawm kev tiv thaiv siab ntawm cov yeeb nkab tseem ua tau raws li qhov xav tau tsim, tus nqi ntawmcov kav dej fiberglasspiv rau qhov tsis muaj kev nce ntxiv tseem ceeb.

Basalt fiber siab siab yeeb nkab ua tau zoo dua:
(1) kev tiv thaiv corrosion zoo heev
Cov fiber basaltCov qauv kav dej siab siab muab faib ua peb ntu: txheej sab hauv, txheej qauv thiab txheej tiv thaiv sab nraud. Ntawm lawv, txheej sab hauv muaj cov roj hmab ntau, feem ntau ntau dua 70%, thiab cov roj hmab ntawm nws cov txheej sab hauv muaj cov roj hmab ntau txog li 95%. Piv nrog cov kav dej hlau, nws muaj kev tiv thaiv corrosion zoo dua, xws li ntau yam kua qaub thiab alkali muaj zog, ntau yam ntsev inorganic, oxidizing media, hydrogen sulfide, carbon dioxide, ntau yam surfactants, polymer solutions, ntau yam organic solvents, thiab lwm yam, tsuav yog xaiv cov roj hmab zoo, cov kav dej siab siab ntawm cov roj basalt tuaj yeem tiv taus ntev (cov kua qaub concentrated, alkali muaj zog, thiab HF tsis suav nrog)
(2) Kev ua haujlwm qaug zog zoo thiab lub neej ntev
Lub neej ua haujlwm ntawm cov kav dej basalt fiber siab yog ntau tshaj 20 xyoo, thiab qhov tseeb, feem ntau tom qab siv ntau tshaj 30 xyoo nws tseem zoo li qub, thiab nws lub neej ua haujlwm tsis tas yuav saib xyuas.
(3) Muaj peev xwm siab siab
Qib siab ib txwm ntawmbasalt fiberCov kav dej siab yog 3.5MPa-25MPa (txog li 35 MPa, raws li phab ntsa tuab thiab suav), piv nrog lwm cov kav dej uas tsis yog hlau, lub peev xwm tiv taus siab dua.
(4) Lub teeb yuag, yooj yim installation thiab kev thauj mus los
Qhov hnyav tshwj xeeb ntawm cov yeeb nkab basalt fiber siab yog li 1.6, tsuas yog cov yeeb nkab hlau lossis cov yeeb nkab hlau cam khwb cia yog 1/4 ~ 1/5, daim ntawv thov qhia tau tias, nyob rau hauv tib lub siab sab hauv, tib lub cheeb, tib qhov ntev ntawm FRP yeeb nkab, nws qhov hnyav yog li 28% ntawm cov yeeb nkab hlau.
(5) lub zog siab, cov khoom siv kho tshuab tsim nyog
Basalt fiber high-pressure yeeb nkab axial tensile zog ntawm 200 ~ 320MPa, ze rau cov yeeb nkab hlau, tab sis ntau dua li lub zog ntawm kwv yees li 4 zaug, hauv kev tsim qauv, yeeb nkab qhov hnyav tuaj yeem txo qis heev, kev teeb tsa yooj yim heev.
(6) Lwm yam khoom:
Tsis yooj yim rau nplai thiab quav ciab, tsis tshua muaj kev ntws tsis kam, zoo hluav taws xob rwb thaiv tsev, kev sib txuas yooj yim, lub zog siab, tsis tshua muaj thermal conductivity, tsis tshua muaj thermal kev ntxhov siab.
