Basalt Fiber ntau: Sab saum toj 10 Qhov Zoo Tshaj

Basalt fiber ntauyog ib tug nruam fiber ntau ua los ntawm ntuj Basalt Pob Zeb. Lub pob zeb yog yaj ntawm 1450 ° C-1500 ° C thiab ces kos los ntawm platinum-rhodium alloy bushing ntawm kev kub ceev. Ntshiab basalt fiber ntau yog xim av. Nws yog ib yam tshiab ntawm inorganic, eco-friendly, high-kev ua tau zoo fiber ntau muaj oxides xws li silicon dioxide, aluminium oxide, calcium oxide, magnesium oxide, hlau oxide, thiab titanium dioxide. Basalt tsis tu ncua fiber ntau tsis tsuas yog muaj lub zog siab, tab sis kuj boasts cov khoom zoo xws li hluav taws xob rwb thaiv tsev, corrosion kuj, thiab kub-resistant. Tsis tas li ntawd, nws cov txheej txheem tsim khoom tsim cov khoom pov tseg tsawg thiab ib puag ncig muaj kuab paug, thiab cov khoom pov tseg tuaj yeem degrade ib txwm tsis muaj teeb meem, ua rau nws yog cov khoom siv ntsuab tiag tiag thiab eco-friendly. Tuam Tshoj tau teev cov basalt fiber ntau ua ib qho ntawm plaub qhov tseem ceeb fibers rau txoj kev loj hlob (nrog rau carbon fiber, aramid, thiab ultra-high molecular hnyav polyethylene) thiab tau ua tiav kev lag luam ntau lawm. Nruam basalt fiber ntau yog tam sim no dav siv nyob rau hauv fiber-reinforced composites, kev sib txhuam cov ntaub ntawv, shipbuilding, automotive kev lag luam, thiab high-kub thiab tiv thaiv daim ntaub ntawv.

1. Raw Khoom Muaj Ntau

   Basalt fiber yog tsim los ntawm pob zeb basalt, uas muaj nyob rau hauv ntau qhov ntau ntawm lub ntiaj teb thiab lub hli. Qhov no ua rau cov khoom siv raw cov nqi qis.

2. Eco-Friendly Khoom

   Basalt pob zeb yog cov khoom siv ntuj tsim. Nws cov txheej txheem tsim khoom tsis tso tawm boron lossis lwm yam alkali hlau oxides, yog li cov plua plav thiab cov pa luam yeeb tsis muaj cov khoom tsis zoo thiab tsis ua rau cov huab cua phem. Cov khoom tseem muaj lub neej ntev, ua rau nws tus nqi qis, kev ua haujlwm siab, thiab cov khoom siv ntsuab tshiab huv si.

3. Kub-kub thiab dej tsis kam

   Tsis tu ncua basalt fiber ntau tuaj yeem ua haujlwm hauv qhov kub ntawm -269 ° C txog 700 ° C (nrog rau qhov muag muag ntawm 960 ° C). Qhov no zoo tshaj gfiber ntau (-60 ° C txog 450 ° C) thiab carbon fiber (max 500 ° C). Qhov tseem ceeb, basalt fiber khaws 80% ntawm nws lub zog qub tom qab ua haujlwm ntawm 600 ° C thiab tsis ntsws ntawm 860 ° C. Nws tseem tuav lub zog siab tom qab raug rau 70 ° C dej kub.

4. Zoo heev tshuaj Stability thiab Corrosion Resistance

   Basalt fiber muaj cov khoom xws li K₂O, MgO, thiab TiO₂, uas txhim kho nws cov tshuaj tiv thaiv corrosion thiab dej. Nws muaj tshuaj ruaj khov dua li iav fiber ntau, tshwj xeeb tshaj yog nyob rau hauv alkaline thiab acidic ib puag ncig. Basalt fiber qhia tau hais tias txawm zoo dua rau alkali corrosion nyob rau hauv saturated Ca (OH)₂ daws thiab xis mas.

5. High Elastic Modulus thiab Tensile Strength

   Basalt fiber ntau elastic modulus (9100-11000 kg / mm) yog siab dua li ntawm E-iav fiber, asbestos, aramid, polypropylene, thiab silicon fibers. Nws lub zog tensile (3800-4800 MPa) yog ntau dua li cov loj-tw carbon fiber, aramid, PBI fiber, steel fiber, boron fiber, thiab alumina fiber, thiab yog piv rau S-iav fiber. Nrog rau qhov ntom ntawm 2.65-3.00 g / cm³ thiab Mohs hardness ntawm 5-9, nws muaj kev hnav zoo heev thiab tensile reinforcement. Nws lub zog txhua yam nyob deb tshaj li ntuj thiab hluavtaws fibers, ua rau nws yog ib qho khoom siv zoo tshaj plaws.

6. Kev ua tau zoo ntawm lub suab rwb thaiv tsev

   Nruam basalt fiber ntau muaj lub suab zoo heev thiab lub suab nrov absorbing zog. Nws lub suab nqus coefficient nce ntxiv nrog zaus. Piv txwv li, cov khoom siv suab nrov ua los ntawm 1-3 μm txoj kab uas hla basalt fibers (nrog rau qhov ceev ntawm 15 kg / m³ thiab thickness ntawm 30 mm) muaj suab nrov coefficients ntawm 0.05-0.15 ntawm 100-300 Hz, 0.22-0.59 ntawm 0.75 Hz ntawm 0.040. 1200-7000 Hz.

7. Prominent Dielectric Properties

   Nruam basalt fiber ntauLub ntim resistivity yog qhov kev txiav txim ntawm qhov loj dua li E-iav fiber ntau, muab nws cov khoom zoo heev dielectric. Txawm hais tias basalt pob zeb muaj ze li ntawm 0.2% conductive oxides, tshwj xeeb nto kho nrog sizing tus neeg sawv cev tuaj yeem txo qhov dielectric poob tangent los ntawm 50% piv rau iav fiber ntau, thiab nws qhov ntim kuj tseem siab dua.

8. Ntuj Silicate Compatibility

   Nws disperses zoo thiab bonds muaj zog nrog cement thiab pob zeb. Nws thermal expansion thiab contraction coefficients zoo ib yam, thiab nws muaj huab cua tsis zoo.

9. Tsawg Moisture Absorption

   Basalt fiber muaj qhov nqus noo noo qis dua 0.1%, uas yog qis dua aramid fiber, pob zeb ntaub plaub, thiab asbestos.

10. Tsawg Thermal conductivity

    Basalt fiber ntau thermal conductivity yog 0.031-0.038 W / m·K, uas yog qis dua aramid fiber, aluminium silicate fiber, E-iav fiber, pob zeb ntaub plaub, silicon fiber, carbon fiber, thiab stainless hlau.
