Cov txiaj ntsig ntawm basalt fiber yog dab tsi?
Ua ntej tshaj, peb yuav tsum nkag siab tias nws yog dab tsi. Hais yooj yim xwb, basalt fiberyog ib qho fiber txuas ntxiv uas tsim los ntawm kev siv cov pob zeb basalt ntuj ua cov khoom siv raw zoo; tom qab dhau los ntawm kev yaj kub siab, nws raug rub sai sai los ntawm platinum-rhodium alloy bushings. Nws cov khoom siv raw muaj ntau thiab pom yuav luag txhua qhov chaw thoob plaws ntiaj teb. Lub hauv paus, nws yog ib qho fiber silicate ntuj; nws cov txheej txheem tsim khoom tsis muaj ntxiv Tshuaj lom neeg cov neeg pabcuam, qhov tseeb uas muab nws nrog qee yam tshwj xeeb intrinsic yam ntxwv.
Tom ntej no, kuv yuav piav qhia txog ntau yam tseem ceeb ntawm kev siv Basalt Fiber taw tes los ntawm taw tes.
1. Cov Khoom Siv Kho Tshuab Zoo Kawg Nkaus
Cov fiber basalt qhia txog lub zog kho tshuab zoo heev. Nws muaj lub zog tensile siab heev, sib piv rau ntau yam fibers reinforcing. Nws cov elastic modulus - ib qho cim qhia txog nws qhov kev tiv thaiv rau elastic deformation - kuj nyob rau theem siab. Qhov no txhais tau tias cov khoom sib xyaw ua ke uas tau txhawb nqa nrog basalt fiber tuaj yeem tiv taus kev tawg thiab zam kev deformation ntau dhau thaum raug rau sab nraud, yog li ua kom pom kev ruaj khov zoo heev. Kev sib xyaw ua ke ntawm lub zog siab thiab modulus siab ua rau nws muaj txiaj ntsig tshwj xeeb rau cov ntawv thov uas muaj cov qauv sib dua, thauj khoom.
2. Kev Tiv Thaiv Thermal Zoo Tshaj Plaws thiab Kev Ruaj Ntseg
Qhov no yog ib qho txiaj ntsig zoo heev ntawm cov fiber basalt. Nws muaj ntau qhov kub thiab txias, muaj peev xwm tiv taus qhov kub siab thaum tswj kev ua haujlwm ruaj khov txawm tias nyob hauv qhov chaw kub qis. Tshwj xeeb, nws muaj ntau yam zoo rau kev siv mus sij hawm ntev, nrog rau kev kam rau siab dua rau kev raug cua sov luv luv. Tsis zoo li qee cov organic fibers, nws tsis yaj lossis hlawv ntawm qhov kub siab, thiab kev puas tsuaj ntawm nws lub cev thiab cov khoom siv kho tshuab tshwm sim qeeb qeeb. Ntxiv mus, nws muaj cov thermal conductivity qis, muab qib ntawm kev rwb thaiv tsev thermal thiab kev tuav cua sov. Cov yam ntxwv no ua rau nws zoo rau cov ntawv thov uas yuav tsum tau ua kom tau raws li cov kev cai tshwj xeeb txog kev tiv thaiv thermal.
3. Kev Ruaj Ntseg Tshuaj Zoo thiab Kev Tiv Thaiv Kev Sib Tsoo
Vim nws cov silicate xwm, basalt fiber muaj zog inertness thaum raug rau cov tshuaj lom neeg. Nws ua rau muaj kev tiv thaiv zoo rau ob qho tib si acidic thiab alkaline cov tshuaj; qhov tseem ceeb, nws qhov ruaj khov hauv alkaline ib puag ncig zoo dua li lwm cov inorganic fibers hauv nws chav kawm. Nws kuj muaj kev tiv thaiv dej zoo heev, ua kom ntseeg tau tias nws cov kev ua tau zoo tsis yooj yim poob qis hauv cov av noo lossis dej hauv qab. Qhov kev tiv thaiv corrosion no tso cai rau nws ua haujlwm tau zoo rau lub sijhawm ntev hauv qhov chaw nyuaj - xws li cov uas pom hauv kev ua tshuaj lom neeg lossis kev lag luam marine - yog li ua rau lub neej kev pabcuam ntawm cov khoom sib xyaw.
4. Cov Khoom Siv Dielectric Zoo Tshaj Plaws thiab Wave Transparency
Cov fiber basalt yog ib qho hluav taws xob tsis zoo, muaj qhov siab resistivity thiab surface resistivity, nrog rau dielectric constants qis thiab dielectric loss tangents. Qhov no ua rau nws "pom tseeb" rau electromagnetic waves, qhia txog cov khoom zoo heev ntawm kev xa xov wave. Tus cwj pwm no tseem ceeb heev hauv cov teb uas xav tau electromagnetic shielding lossis wave transparency - piv txwv li, hauv qee yam khoom ntawm cov khoom siv sib txuas lus.
5. Kev Sib Haum Xeeb thiab Kev Nyab Xeeb rau Ib puag ncig uas Tus Neeg Siv Txaus Siab
Txij li cov khoom siv raw mus rau cov khoom tiav, tag nrho lub neej ntawm basalt fiber yog tus cwj pwm los ntawm nws tus phooj ywg ib puag ncig. Nws cov khoom siv hluav taws xob tsawg thiab tsis tsim cov pa roj phem. Cov khoom nws tus kheej tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis khaus thaum kov cov tawv nqaij tib neeg; ntxiv rau, nws tsis tsim cov hmoov av uas ua rau tib neeg noj qab haus huv thaum lub sijhawm tsim khoom lossis siv. Thaum pov tseg, nws tuaj yeem rov ua dua tshiab rau hauv lub voj voog geological ntuj yam tsis ua rau muaj kuab paug, ua rau nws yog cov khoom siv "ntsuab" quintessential.
6. Kev Tiv Thaiv Dej Ntuj thiab Kev Nqus Tau
Cov fiber basalt Nws muaj ib qho chaw du thiab tsis yooj yim hydrophobic, ua rau nws nqus dej tsawg heev. Qhov no ua kom cov khoom siv los ntawm nws ua haujlwm ruaj khov txawm tias nyob hauv qhov chaw noo. Thaum raug kev kho tshwj xeeb, nws qhov chaw tshwj xeeb tuaj yeem nce ntxiv, ua rau nws muaj peev xwm nqus tau zoo rau qee yam tshuaj - ib qho tshwj xeeb uas qhib rau nws siv rau hauv cov teb xws li kev lim dej thiab kev tiv thaiv ib puag ncig.
Tau kawg, tsis muaj cov khoom siv uas tsis muaj nws cov kev txwv. Basalt fiber muaj qee qhov kev txwv; piv txwv li, nws cov txheej txheem tsim khoom xav tau qib siab ntawm kev sib xws hauv cov khoom siv raw, txhais tau tias cov khoom ntawm basalt los ntawm ntau qhov chaw sib txawv yuav qhia txog kev hloov pauv. Tsis tas li ntawd, lub zog sib txuas ntawm cov fiber thiab resin matrices feem ntau xav tau kev ua kom zoo dua los ntawm kev kho qhov chaw. Ntxiv mus, nws cov nqi tsim khoom tam sim no tseem siab dua li cov ntawm qee cov fibers tsim tawm ntawm qhov loj heev ntawm kev lag luam. Kev daws cov teeb meem tshwj xeeb no yog qhov tseem ceeb rau kev tshawb fawb thiab kev siv zog ua lag luam hauv cov lag luam cuam tshuam.
Hauv kev xaus, basalt fiber sib xyaw ua ke ntau yam zoo tshaj plaws - suav nrog lub zog siab, kev tiv taus cua sov zoo heev, kev tiv taus corrosion, cov khoom rwb thaiv hluav taws xob, thiab kev phooj ywg ib puag ncig - rau hauv ib yam khoom. Cov yam ntxwv no tau ua rau nws pom kev siv tau thoob plaws ntau qhov chaw: hauv kev thauj mus los ntawm txoj kev, nws yog siv los txhawb cov pob zeb thiab kho thiab txhawb cov choj thiab cov chaw ntawm txoj kev; hauv kev tsim kho, nws yog siv rau hauv kev tsim cov khoom siv hluav taws kub thiab cov khoom rwb thaiv cua sov, nrog rau cov ntaub thaiv phab ntsa; hauv kev tiv thaiv ib puag ncig, nws yog siv los tsim cov hnab lim dej kub thiab cov khoom siv adsorption; hauv cov khoom siv hauv dej hiav txwv thiab tsheb, nws yog siv los tsim cov khoom sib xyaw ua ke; thiab hauv kev lag luam hluav taws xob thiab hluav taws xob, nws ua haujlwm hauv kev tsim cov khoom siv hluav taws xob, cov khoom rwb thaiv tsev, thiab ntau ntxiv. Nws cov kev cia siab ntawm daim ntawv thov txuas ntxiv mus txuas ntxiv mus raws li cov thev naus laus zis hauv qab no loj hlob tuaj.
Raws li cov fiber ua tau zoo "hloov pauv" los ntawm pob zeb volcanic, basalt fiber tau maj mam tsim ib qho chaw tshwj xeeb rau nws tus kheej hauv ntiaj teb ntawm cov ntaub ntawv engineering, ua tsaug rau nws cov khoom sib xyaw ua ke. Nws qhia tau hais tias qhov xwm txheej ntawm qhov muaj txiaj ntsig tuaj yeem siv tau li cas - los ntawm lub zog ntawm cov thev naus laus zis niaj hnub - thiab hloov pauv mus rau hauv cov ntaub ntawv tshiab uas pab txhawb kev nce qib ntawm lub zej zog. Saib rau pem hauv ntej, thaum cov txheej txheem npaj txuas ntxiv txhim kho thiab kev tshawb fawb txog kev siv tob zuj zus, peb tuaj yeem cia siab tias yuav pom "xov pob zeb" no ua lub luag haujlwm tseem ceeb hauv ntau qhov xwm txheej.
