Imathiriyeli entsha ye-inorganic eluhlaza esebenza kakhulu kwifayibha iBasalt Fiber

Yintoni iFayibha yeBasalt?
Ifayibha ye-Basalt yifiber eqhubekayo eyenziwe ngelitye le-basalt yendalo njengeyona nto iphambili.Emva kokunyibilika kwi-1450-1500 ℃, izotywa ngeplatinam-rhodium alloy drawing bushing ngesantya esiphezulu.Umbala ngokubanzi umdaka kwaye unokukhanya kwesinyithi.Iqulunqwe ngeeoksidi ezifana ne-silicon dioxide, i-aluminium oxide, i-calcium oxide, i-magnesium oxide, i-iron oxide kunye ne-titanium dioxide.Ifayibha yeBasalt ineepropathi ezininzi ezigqwesileyo ezinje ngokuqina okuphezulu, ukugqunywa kombane, ukuxhathisa umhlwa, ukumelana nobushushu obuphezulu, ukulwa nokuguga, njl., kwaye iyahambelana kakuhle nokusingqongileyo kwaye ayivelisi ungcoliseko lwesibini.Ke ngoko, yimathiriyeli entsha yokhuseleko lwendalo eluhlaza esebenza ngokuphezulu.
ilizwe lam lidwelise i-basalt fiber njengenye yeentsinga ezine eziphambili (i-carbon fiber, i-aramid fiber, i-ultra-high molecular weight polyethylene, i-basalt fiber) yophuhliso oluphambili.Iimfuno zohambo ngenqwelomoya kunye neminye imimandla inamathuba abanzi okusebenza.
Inkqubo yokuvelisa i-basalt fiber
Ilitye lendalo le-basalt elenziwe ngokugqabhuka kwentaba-mlilo lisetyenziswa njengento ekrwada, lityunyuziwe kwaye lifakwe kwiziko lokunyibilika, lifudunyezwe kwindawo etyhidiweyo ye-1450 ~ 1500 ° C, kwaye litsalwe ngokukhawuleza nge-platinum-rhodium alloy wire drawing bushing, kunye ne-basalt fiber. iveliswa ngolu hlobo.
Ngamafutshane, inkqubo yokwenza i-basalt fiber "kukutsala" ilitye elinzima le-volcanic basalt kwisilika kwiqondo lokushisa eliphezulu.
Ububanzi befiber ye-basalt eveliswa yiteknoloji ekhoyo inokufikelela kwi-6 ~ 13μm, encinci kuneenwele.
Inkqubo yokuvelisa kwayo iboniswe kumzobo ongezantsi.

Magma atyhidiweyo

Umzobo
Njenge-amorphous inorganic silicate substance, i-basalt fiber inexesha elifutshane lokuvelisa, inkqubo elula, akukho manzi amdaka amashishini kunye negesi yenkunkuma, kunye nexabiso eliphezulu elongezelelweyo.Yaziwa ngokuba "yinto entsha eluhlaza" kwinkulungwane yama-21.

Ukusebenza okugqwesileyo kwe-basalt fiber
Imicu ye-basalt ecocekileyo yendalo eqhubekayo inombala wegolide kwaye ibonakala njengeesilinda ezigudileyo kunye ne-cross-section ejikelezayo.Ifayibha ye-Basalt inoxinano oluphezulu kunye nobunzima obuphezulu, ngoko inokumelana nokunxiba okugqwesileyo kunye nokomelela kokuqina.Ifayibha ye-Basalt yinto ye-amorphous, kwaye ubushushu benkonzo yayo ngokuqhelekileyo bu-269 ~ 700 ° C (indawo yokuthambisa yi-960 ° C).Iyaxhathisa iasidi kunye nealkali, inokumelana okuqinileyo kwe-UV, i-hygroscopicity ephantsi, kunye nokuxhathisa okulungileyo kokusingqongileyo.Ukongeza, ineenzuzo zokugquma okulungileyo, ukuhluzwa kobushushu obuphezulu, ukuchasana nemitha kunye nokungenwa kakuhle kwamaza, uzinzo lobushushu bobushushu, ukucoceka kokusingqongileyo kunye nomlinganiselo obalaseleyo wokusebenza kolwakhiwo kumgangatho wesakhiwo.

Imathiriyeli ekrwada eyaneleyo
Ifayibha ye-basalt yenziwa ngokuzoba emva kokunyibilika kwentsimbi ye-basalt, kwaye oovimba be-basalt ore emhlabeni nenyanga banenjongo, kwaye ixabiso lezinto eziluhlaza liphantsi.
Izixhobo ezihambelana nokusingqongileyo
I-Basalt ore yinto yendalo, akukho boron okanye enye i-alkali oxides yensimbi ekhutshwayo ngexesha lenkqubo yokuvelisa, ngoko akukho zinto ezinobungozi zichithwa emsini kunye nothuli, kwaye aziyi kungcolisa umoya.Ngaphezu koko, imveliso inobomi obude benkonzo, ngoko luhlobo olutsha lwezinto eziluhlaza ezisebenzayo zokukhusela okusingqongileyo kunye neendleko eziphantsi, ukusebenza okuphezulu kunye nokucoceka okufanelekileyo.
Ubushushu obuphezulu kunye nokumelana namanzi
Umgangatho wokushisa osebenzayo we-basalt fiber eqhubekayo ngokuqhelekileyo -269 ~ 700 ° C (i-softening point yi-960 ° C), ngelixa i-fiber yeglasi i-60 ~ 450 ° C, kwaye ubushushu obuphezulu bokusebenza kwe-carbon fiber inokufikelela kuphela kwi-500. °C.Ngokukodwa xa i-basalt fiber isebenza kwi-600 ° C, amandla ayo emva kokuphuka angakwazi ukugcina i-80% yamandla ayo okuqala;xa isebenza kwi-860 ° C ngaphandle kokuncipha, nokuba uboya bamaminerali obunokumelana nobushushu obugqwesileyo bunokugcina kuphela ngeli xesha amandla emva kokuphuka.I-50% -60%, uboya beglasi butshatyalaliswa ngokupheleleyo.I-carbon fiber ivelisa i-CO kunye ne-CO2 malunga ne-300 ° C.I-Basalt fibers inokugcina amandla aphezulu phantsi kwesenzo samanzi ashushu kwi-70 ° C, kunye ne-basalt fibers inokulahlekelwa inxalenye yamandla emva kwe-1200 h.
Uzinzo oluhle lweekhemikhali kunye nokumelana nokubola
I-basalt fiber eqhubekayo iqulethe amacandelo afana ne-K2O, i-MgO) kunye ne-TiO2, kwaye la macandelo anenzuzo kakhulu ekuphuculeni ukuxhatshazwa kweekhemikhali ze-corrosion kunye nokusebenza kwamanzi kwifiber, kwaye idlala indima ebaluleke kakhulu.Xa kuthelekiswa nokuzinza kweekhemikhali zefiber yeglasi, ineenzuzo ezininzi, ngakumbi kwimidiya ye-alkaline kunye ne-acidic.Ifayibha ye-Basalt inokugcina ukuchasana okuphezulu kwisisombululo se-Ca (OH) esigcweleyo se-2 kunye nemidiya ye-alkaline njengesamente.Iimpawu zokubola kwealkali.
Imodyuli ephezulu yokuqina kunye namandla okuqina
I-elastic modulus ye-basalt fiber yile: 9100 kg / mm-11000 kg / mm, ephezulu kune-alkali-free glass fiber, asbestos, fiber aramid, polypropylene fiber kunye ne-silicon fiber.Amandla anamandla e-basalt fiber yi-3800-4800 MPa, ephakamileyo kunaleyo ye-carbon fiber enkulu, i-aramid, i-PBI fiber, i-fiber fiber, i-boron fiber, kunye ne-alumina fiber, kwaye ifaniswa ne-S glass fiber.Ifayibha ye-Basalt inobunzima be-2.65-3.00 g/cm3 kunye nobunzima obuphezulu be-5-9 kwisikali se-Mohs, ngoko inokumelana nokunxiba okugqwesileyo kunye namandla okuqina.Amandla ayo omatshini ayodlula kude lee iintsinga zendalo kunye neentsinga zokwenziwa, ngoko iyimathiriyeli efanelekileyo yokomeleza, kwaye iimpawu zayo ezibalaseleyo zoomatshini ziphambili kwimicu emine yokusebenza okuphezulu.
Ukufakwa kwesandi okugqwesileyo
I-basalt fiber eqhubekayo ine-insulation egqwesileyo yesandi kunye neempawu zokufunxa isandi.Iyakwazi ukwaziwa ukusuka kwi-coefficient yokufunxa isandi sefiber kwiifrikhwensi ezahlukeneyo ukuba i-coefficient yokufunxa isandi inyuka kakhulu njengoko i-frequency inyuka.Ngokomzekelo, ukuba i-sound-absorbing material eyenziwe nge-basalt fiber kunye nobubanzi be-1-3μm (ubuninzi be-15 kg / m3, ubukhulu be-30mm) ikhethiwe, i-fiber ayiyi konakaliswa phantsi kwemeko yomsindo we-100-300 Hz. , 400-900 Hz kunye ne-1200-7 000 HZ.I-coefficients yokufunxa isandi semathiriyeli ngu-0. 05~0.15, 0. 22~0.75 kunye ne-0.85 ~ 0.93, ngokulandelanayo.
IiPropati ezibalaseleyo zeDielectric
I-volume resistivity ye-basalt fiber eqhubekayo i-oda lobukhulu obuphezulu kune-fiber ye-glass ye-E, kwaye ineempawu ezintle ze-dielectric.Nangona i-basalt ore iqulethe i-oxide conductive kunye neqhekeza elikhulu eliphantse libe yi-0.2, emva konyango olukhethekileyo lomphezulu kunye ne-agent ekhethekileyo yokumanzisa, i-dielectric loss tangent ye-basalt fiber yi-50% ephantsi kune-fiber yeglasi, kunye nomthamo we-resistiveivity yefiber. Ikwaphezulu kunolo lwefiber yeglasi.
Ukuhambelana kweSilicate yendalo
Inokusasazwa kakuhle ngesamente kunye nekhonkrithi, amandla okubopha olomeleleyo, ukwandiswa kwe-thermal kunye nokunciphisa i-coefficient, kunye nokumelana nemozulu elungileyo.
I-hygroscopicity ephantsi
I-hygroscopicity ye-basalt fiber ingaphantsi kwe-0.1%, ephantsi kune-fiber aramid, i-rock wool kunye ne-asbestos.
I-conductivity ephantsi ye-thermal
I-thermal conductivity yefayibha ye-basalt yi-0.031 W/m·K -0.038 W/m·K, engaphantsi kunefayibha ye-aramid, i-aluminium silicate fiber, i-alkali-free glass fiber, i-rock wool, i-silicon fiber, i-carbon fiber kunye ne-stainless. intsimbi.
Xa kuthelekiswa nezinye iifiber, ifayibha ye-basalt inomsebenzi ogqwesileyo kwiinkalo ezininzi.
