Nkag siab txog Basalt Fibers PartⅠ

Tshuaj muaj pes tsawg leeg ntawm basalt
Nws yog paub zoo tias lub ntiaj teb crust yog tsim los ntawm igneous, sedimentary thiab metamorphic pob zeb.Basalt yog ib hom pob zeb uas tsis muaj zog.Igneous pob zeb yog pob zeb tsim thaum magma erupts underground thiab condenses rau saum npoo.Igneous pob zeb uas muaj ntau tshaj 65% SiO₂yog cov pob zeb acidic, xws li granite, thiab cov uas muaj tsawg dua 52% S0 yog hu ua pob zeb yooj yim, xws li basalt.Nruab nrab ntawm ob yog cov pob zeb nruab nrab xws li andesite.Ntawm cov khoom siv basalt, cov ntsiab lus ntawm SiO₂yog feem ntau ntawm 44% -52%, cov ntsiab lus ntawm Al₂O₃yog nruab nrab ntawm 12% -18%, thiab cov ntsiab lus ntawm Fe0 thiab Fe₂0₃yog nyob nruab nrab ntawm 9% -14%.
Basalt yog cov khoom siv hluav taws xob refractory nrog lub melting kub tshaj 1500 ℃.Cov ntsiab lus hlau siab ua rau fiber ntau bronze, thiab nws muaj K₂O, MgO and TiO₂uas ua lub luag haujlwm tseem ceeb hauv kev txhim kho cov dej tsis zoo thiab kev tiv thaiv corrosion ntawm fiber ntau.
Basalt ore belongs rau volcanic magma ore, uas muaj ntuj tshuaj stability.Basalt ore yog ib qho khoom siv raw khoom rau kev ntxiv, melting thiab zoo ib yam.Tsis zoo li iav fiber ntau lawm, basalt fiber ntau cov ntaub ntawv raw khoom yog ntuj thiab npaj ua.

Nyob rau hauv xyoo tas los no, ntau txoj haujlwm tshawb fawb tau ua tiav los tshuaj xyuas cov ores tsim nyog rau kev tsim cov khoom siv basalt fiber ntau txuas ntxiv, tshwj xeeb tshaj yog rau kev tsim cov basalt fibers nrog cov yam ntxwv (xws li lub zog txhua yam, tshuaj lom neeg thiab thermal stability, hluav taws xob rwb thaiv tsev, thiab lwm yam), tshwj xeeb ores yuav tsum tau siv tshuaj muaj pes tsawg leeg thiab fiber ntau txoj kev.Piv txwv li: qhov ntau ntawm ore tshuaj muaj pes tsawg leeg siv nyob rau hauv zus tau tej cov basalt fiber ntau yog qhia nyob rau hauv lub rooj.

Xwm tau muab lub zog tseem ceeb ntawm basalt ore.Nyob rau hauv tej yam ntuj tso tej yam kev mob, basalt ore undergoes enrichment, homogenization ntawm tshuaj Cheebtsam thiab melting nyob rau hauv qhov tob ntawm lub ntiaj teb.Txawm tias qhov xwm txheej xav thawb basalt ore mus rau saum npoo ntawm lub ntiaj teb nyob rau hauv daim ntawv ntawm roob rau tib neeg siv.Raws li kev txheeb cais, kwv yees li 1/3 ntawm lub roob yog tsim los ntawm basalt.
Raws li kev soj ntsuam cov ntaub ntawv ntawm cov tshuaj muaj pes tsawg leeg ntawm basalt ore, basalt raw cov ntaub ntawv yog yuav luag tag nrho cov thoob lub teb chaws, thiab tus nqi yog 20 yuan / tuj, thiab tus nqi ntawm raw cov ntaub ntawv yuav raug ignored nyob rau hauv lub zus tau tej cov nqi ntawm basalt fiber.Muaj cov chaw mining tsim nyog rau kev tsim cov basalt fiber ntau txuas ntxiv hauv ntau lub xeev hauv Suav teb, xws li: plaub, Heilongjiang, Yunnan, Zhejiang, Hubei, Hainan Island, Taiwan thiab lwm lub xeev, qee qhov tau tsim cov basalt fiber ntau txuas ntxiv ntawm cov khoom siv kuaj.Suav basalt ores txawv ntawm European ores.Los ntawm ib qho kev xav ntawm geological, Suav basalt ores kuj yog "cov tub ntxhais hluas", thiab lawv tsis muaj cov yam ntxwv tshwj xeeb, uas yog, lub npe hu ua thawj ore nti.Los ntawm kev txheeb xyuas ntawm Suav xeev xws li Sichuan, Heilongjiang, Yunnan, Zhejiang, thiab Hubei, txoj kev kawm ntawm basalt ores nyob rau hauv nruab nrab thiab qis mus txog ntawm tus dej Yangtze, Hainan thiab lwm cheeb tsam qhia tau hais tias tsis muaj thawj pob zeb nyob rau hauv cov basalt ores. , thiab tsuas muaj qee cov xim daj hlau oxide nyias txheej ntawm qhov chaw.Qhov no muaj txiaj ntsig zoo rau kev tsim cov basalt fiber ntau tas li, thiab cov khoom siv raw khoom thiab cov nqi ua haujlwm tsawg.
Basalt yog ib qho inorganic silicate.Nws tau raug tempered nyob rau hauv volcanoes thiab furnaces, los ntawm cov pob zeb tawv mus rau mos fibers, lub teeb teev, thiab tawv tuav.Cov khoom muaj qhov kub thiab txias tsis kam (> 880C) thiab tsis kub tsis kam (<-200C), thermal conductivity (kub rwb thaiv tsev), suab rwb thaiv tsev, nplaim retardant, rwb thaiv tsev, tsis tshua muaj noo noo nqus, corrosion kuj, hluav taws xob tsis kam, siab tawg zog, Tsawg elongation, siab elastic modulus, lub teeb yuag thiab lwm yam kev ua tau zoo thiab kev ua haujlwm zoo heev, Nws yog cov khoom siv tshiab tag nrho: nws tsis tsim cov tshuaj lom hauv cov txheej txheem tsim khoom thiab kev ua haujlwm, thiab tsis muaj cov pa khib nyiab, dej khib nyiab, thiab pov tseg. residue paug, yog li nws yog hu ua tsis muaj kuab paug "ntsuab industrial khoom thiab cov khoom tshiab" nyob rau hauv lub xyoo pua 21st.
Piv nrog cov iav fiber ntau, uas yog siv dav hauv kev tsim kho, tshuaj lom neeg kev lag luam thiab lwm yam lag luam, nws yog qhov pom tseeb tias basalt fiber ntau thiab nws cov ntaub ntawv sib xyaw muaj lub zog txhua yam, zoo lub cev thiab tshuaj lom neeg, thiab tuaj yeem siv los ua cov khoom lag luam siab.Piv nrog rau lwm cov ntaub ntawv, tag nrho cov kev ua tau zoo ntawm ob yog sib piv.Qee cov khoom ntawm basalt fiber ntau zoo dua li cov pa roj carbon fiber ntau, thiab nws cov nqi tsawg dua li ib feem kaum ntawm carbon fiber raws li tus nqi lag luam tam sim no.Yog li ntawd, basalt fiber yog ib qho tshiab fiber ntau nrog tus nqi qis, kev ua haujlwm siab thiab kev huv zoo tshaj plaws tom qab carbon fiber, aramid fiber thiab polyethylene fiber.Tebchaws Asmeskas Texas Basalt Continuous Fiber Industry Alliance tau taw qhia tias: "Basalt txuas ntxiv fiber ntau yog tus nqi qis rau cov pa roj carbon fiber ntau thiab muaj cov khoom zoo heev.Qhov tseem ceeb tshaj plaws, vim hais tias nws yog muab los ntawm ntuj ore tsis muaj additives, nws yog nyob deb ntawm tsuas yog ib puag ncig muaj kuab paug thiab tsis muaj tshuaj lom.Carcinogenic ntsuab thiab noj qab haus huv iav fiber ntau cov khoom muaj kev lag luam dav thiab kev thov ua ntej "
Basalt ore tau muab tso rau saum npoo ntawm lub ntiaj teb rau ntau lab xyoo thiab tau raug rau ntau yam huab cua.Basalt ore yog ib qho ntawm cov muaj zog silicate ores.Fibers ua los ntawm basalt muaj lub zog ntuj thiab ruaj khov tiv thaiv corrosive media.Durable, hluav taws xob insulating, basalt ore yog lub ntuj thiab ib puag ncig zoo huv si raw khoom.
