Kev tshuaj xyuas ntawm daim ntawv thov ntawm cov fibers basalt txuas ntxiv mus rau hauv cov cim qhia kev taw qhia
Thaum piv rau tus kheej Tshuaj lom neeg lossis cov khoom siv kho tshuab, cov fibers high-tech nrog cov yam ntxwv zoo dua rau kev txuas ntxiv musbasalt fiber(CBF) tuaj yeem pom. Txawm li cas los xij, thaum xav txog kev ua tau zoo, CBF tshwm sim ua qhov zoo tshaj plaws "versatile" fiber. Tshaj li nws lub zog siab, modulus siab, thiab cov yam ntxwv siab heev, CBF qhia tau tias muaj kev tiv thaiv zoo rau acid / alkali corrosion, kub heev, hluav taws xob, thiab oxidation. Nws kuj qhia tau tias muaj kev rwb thaiv tsev thermal / acoustic zoo heev, kev ua haujlwm lim dej, hluav taws kub retardancy, siab compressive thiab shear zog, nrog rau kev hloov pauv zoo rau ntau qhov chaw. Cov khoom no ua rau nws muaj txiaj ntsig zoo hauv kev txo qhov hnyav ntawm cov qauv thaum tsim cov tshiab Cov Khoom Siv Sib XyawsXav txog qhov chaw ua haujlwm thiab cov yam ntxwv ntawm cov khoom siv pab navigation, CBF thiab nws cov khoom sib xyaw ua ke muaj cov txiaj ntsig sib txawv rau kev tsim cov buoy bodies, beacon structures, thiab cov cim zoo tshaj plaws:
(1) Lub teeb yuag thiab muaj zog heev
Piv rau hlau, CBF muaj zog tensile peb npaug (ntau tshaj 1,000 MPa) thaum tswj tau tsuas yog ib feem plaub ntawm cov hlau qhov ceev. Qhov no ua rau kev thauj mus los, kev tsa, thiab kev saib xyuas yooj yim dua nrog kev txuag nyiaj ntau. Nws cov modulus elastic zoo, lub zog tensile, thiab elongation thaum tawg ua kom muaj kev ruaj khov ntawm cov qauv thaum muaj kev sib tsoo me me nrog cov nkoj.
(2) Kev Tiv Thaiv Kev Sib Tsoo Zoo Tshaj Plaws thiab Lub Neej Ntev
CBF ua pov thawj tias nws tiv taus cov tshuaj lom neeg zoo heev rau cov kua qaub, alkalis, ntsev, thiab cov chaw nyob hauv dej hiav txwv. Cov khoom siv yeeb nkab uas tsim los ntawm CBF yog tsim los rau lub neej ua haujlwm 50 xyoo, nrog cov kws tshaj lij khoom siv hauv Kaus Lim Qab Teb kwv yees tias nws yuav siv tau ntev tshaj ib puas xyoo. Cov khoom siv pab txhawb nqa kev tsav nkoj uas ua los ntawm CBF tshem tawm qhov xav tau cov txheej tiv thaiv xeb lossis kev tiv thaiv cathodic. Nws qhov kev ua tau zoo hauv kev lag luam tsim nkoj hauv Suav teb - siv dav hauv cov hulls, chav tsev cav rwb thaiv tsev, thiab cov qauv saum toj kawg nkaus - ua pov thawj tias nws tiv taus xeb dej hiav txwv zoo heev.
(3) Kev Siv Nyiaj Zoo thiab Kev Txij Nkawm Tsawg
Siv cov khoom siv basalt ntau uas tau muab faib thoob plaws ntiaj teb, CBF cov khoom siv raw muaj ntau dua li cov khoom siv hlau. Nrog rau cov thev naus laus zis tsim khoom loj hlob los ntawm Tuam Tshoj Lub Tebchaws 863 Program, nws cov nqi tsim khoom tau sib piv rau E-iav fiber. Kev ruaj khov tshuaj lom neeg ntawm CBF tshem tawm cov kev xav tau kev saib xyuas ntau zaus xws li kev tshem xeb thiab pleev xim dua rau cov hlau buoys, yog li txo cov nqi siv lub neej, kev siv zog ua haujlwm, thiab kev cuam tshuam rau ib puag ncig. Cov hlau buoys tam sim no hauv cov dej sab qaum teb Suav xav tau kev tshem tawm biofouling txhua xyoo, pleev xim dua, thiab xa mus los ntawm cov nkoj loj - cov txheej txheem uas muaj kev txhawj xeeb txog ib puag ncig thiab kev puas tsuaj. Cov hlau ib txwm muaj lossis FRP beacons raug kev txom nyem los ntawm kev saib xyuas luv luv, cov nqi siab, lossis cov teeb meem deformation, thaum cov polyethylene buoys hnyav molecular siab ntsib cov kev txwv nqi.
